    [0001] The invention relates to a method and device for drug delivery and, in particular, to a nebulizer used for drug delivery and to a method for operating such a nebulizer. BACKGROUND OF THE INVENTION
    [0002] Nebulizers or atomizers, as they are sometimes called, are devices that generate a spray or fine aerosol, usually of liquid. A particularly useful administration for nebulizers is to provide a fine spray containing a dissolved or suspended particulate drug for administration by inhalation to a patient.
    [0003] Nebulizers based on a piezoelectric mesh are commonly used to generate aerosols in such a drug delivery device, whereby a piezoelectric element vibrates a mesh to produce the fine aerosol spray. In particular, droplets dispensed in the mesh are vibrated by the piezoelectric element to create the spray. There are two main models in such nebulizers based on piezoelectric mesh. US patents US5938117 and US6983747 disclose a type of model, whereby the piezoelectric element is connected to a mesh element, whereas US patents US6651650 and US6405934 reveal models by which the mesh element is separated from the piezoelectric element. An advantage of having the mesh element separate from the piezoelectric element is that the mesh element is cheaper to manufacture and therefore can be replaced more often.
    [0004] However, a common disadvantage of all piezoelectric mesh-based nebulizers is that a user needs to clean the mesh after use, otherwise the holes in the mesh may be blocked. In the region, there are 5000 2 μm holes in a typical mesh, and it can easily be blocked by particles in the environment or from all saline crystals (that is, since the drugs are usually saline-based).
    [0005] The cleaning method is usually to wash the mesh in warm water with detergent for approximately five minutes, then rinse and dry the mesh. This process can take as long as the treatment of the drug itself, so it is the patient's responsibility. Thus, over time, even with good cleaning, the mesh performance will deteriorate the more holes become blocked - this can typically happen after several weeks. Once the mesh is blocked, it is very difficult to clean the mesh and remove a particle that is housed in an orifice, so it is necessary to replace the mesh. Although the meshes are designed to last up to twelve months, they usually need to be replaced every three months or even monthly for some patients due to poor cleaning.
    [0006] Such a drug delivery device also typically comprises one or more interchangeable parts, for example, interchangeable mouthpieces, interchangeable plunger assemblies and / or interchangeable medication chambers. These interchangeable parts allow a nebulizer to be adapted or customized to better suit the needs of a specific patient. For example, different mouthpieces can be selected depending on the volume of inhalation preferred by a specific user, while different medication chambers can be selected to provide different volumes depending on the drug to be administered.
    [0007] A disadvantage of having such interchangeable parts is that the drug delivery device must know which specific part of a set of interchangeable parts will fit at any given time, so that the drug delivery device is able to control drug delivery properly.
    [0008] It is an object of the present invention to provide a drug delivery system that helps to alleviate or reduce one or more of the disadvantages mentioned above. SUMMARY OF THE INVENTION
    [0009] According to a first aspect of the invention, a nebulizer is provided which comprises a removable component which comprises a data carrier, and a data reader for communicating with the data carrier of the removable component.
    [0010] The removable component can be one of a set of associated removable components. The data reader thus allows the nebulizer to determine which removable component from the set of removable components is attached to the nebulizer, thus allowing the operation of the nebulizer to be properly controlled.
    [0011] According to another aspect of the invention, a method is provided for operating a nebulizer, the method comprising the steps of receiving information from a data carrier associated with a removable component of the nebulizer and controls the operation of the nebulizer based on the information received from the data bearer.

    [0014] According to another aspect of the invention, a medication chamber for use with a drug delivery device is provided, the medication chamber comprising a data carrier for communicating, in use, with a data reader provided in the nebulizer.
    [0015] According to another aspect of the invention, a measuring chamber for use with a drug delivery device is provided, the measuring chamber comprising a data carrier for communicating, in use, with a data reader provided in the nebulizer. The data carrier provides information related to the dose of drug measured to the nebulizer.
    [0016] According to another aspect of the invention, a plunger assembly is provided for use with a drug delivery device, the plunger assembly comprising a data carrier for communicating, in use, with a data reader provided in the nebulizer. BRIEF DESCRIPTION OF THE DRAWINGS
    [0017] For a better understanding of the present invention and to show more clearly how this can be done efficiently, reference will now be made, by way of example only, to the drawings in which: Figure 1 shows a nebulizer, according to an embodiment of the present invention; Figures 2a to 2c show a mesh assembly of a nebulizer in greater detail, according to another embodiment of the invention; Figures 3a to 3c show a mesh assembly of a nebulizer in greater detail, according to another embodiment of the invention; Figure 4 shows a flow chart that describes the steps performed by an embodiment of the present invention; Figure 5 shows a nebulizer, according to another embodiment of the present invention; Figure 6 shows a flow chart that describes the steps performed by an embodiment of the present invention; Figure 7 shows a flow chart that describes the steps performed by an embodiment of the present invention; and Figure 8 shows a nebulizer, according to another embodiment of the present invention. DETAILED DESCRIPTION OF ACHIEVEMENTS
    [0018] The achievements below will be described in relation to the piezo-mesh device for drug delivery. It is observed, however, that some achievements are not necessarily limited to such a piezo-mesh device for drug administration, for example, the achievements related to nebulizers with interchangeable components, such as inlets and medication chambers. Additionally, it is noted that the term nebulizer can be used interchangeably with the term drug delivery device or atomizer, and it is intended to cover other forms and models of nebulizer in addition to the specific type of nebulizer described below and illustrated in the Figures.
    [0019] Figure 1 shows a nebulizer 1, according to an embodiment of the present invention. The nebulizer 1 comprises a body 3 that receives one or more removable components (i.e. interchangeable parts), such as a mouthpiece 5, a plunger assembly 7 and a mesh assembly 9. The mesh assembly 9 comprises a mesh 9b, which is vibrated by a piezoelectric element to generate a fine spray or aerosol. According to one aspect of the invention, the mesh set 9 also comprises a data carrier 9a. The data carrier 9a communicates with a data reader 11 mounted on the nebulizer 1, for example, on the body of the nebulizer. In this specific embodiment, data carrier 9a comprises an RFID tag (radio frequency-identification and data reader 11 an antenna, each comprising a coil (with Figure 1 showing a cross section of each coil loop, the surfaces of the coil being perpendicular to the image surface). The operation of an RFID tag and an antenna will be apparent to the technician in the subject. The invention is intended to cover the use of any type of RFID tag use system including, among others , passive RFID tags (that is, that are powered from the energy received from the associated antenna), or active RFID tags (that are, that are self-powered.) As discussed later in the patent application, other forms are also provided for data bearer and data reader, without departing from the scope of the invention.
    [0020] Data carrier 9a associated with mesh 9b provides information related to mesh 9b to nebulizer 1, as will be described later in the patent application.
    [0021] In the realization of Figure 1, it can be observed that the body of the mesh set 9 also forms a medication chamber 13. In this way, the data carrier 9a can also be used to provide information related to the medication chamber 13 to the nebulizer 1. The plunger assembly 7 comprises a medication measurement chamber 15. The medication measurement chamber 15 is arranged to feed the drug to be nebulized to the nebulizer nebulizer device, while the medication chamber 13 is arranged to hold and retain any drug in excess of the volume held in the medication measurement chamber 15. This allows a single dose (ie vial) of a drug to be nebulized to be poured into a container, but only the measured volume of the medication measurement chamber 15 to be nebulized during treatment, with the remainder or excess of the drug will be retained in the medication chamber 13. Additional details of the medication measurement chamber 15 and its operation can be found in US patent US2003 / 0146300A1.
    [0022] Although the realization of Figure 1 shows the medication chamber 13 being formed using the mesh set 9, it is observed that the medication chamber can be formed as a separate physical entity, in which the medication chamber would have a separate data carrier to provide information related to the medication chamber to the nebulizer (ie, a data carrier separate from the carrier associated with the mesh).
    [0023] Figures 2a to 2c show in greater detail a mesh set 9 that is configured differently from the mesh set 9 of Figure 1. Figure 2a shows a plan view of the mesh set 9. Figure 2b shows a side sectional view through section XX of Figure 2a. The mesh set 9 of that specific embodiment is configured so that the data carrier 9a and the mesh 9b are on the same surface, that is, coplanar. This has the advantage of allowing the mesh set 9 to be attached to the drug package. Figure 2c shows a final view of the mesh set 9. It will be appreciated in that specific embodiment that the mesh set 9 does not form a medication chamber 13, as shown in Figure 1, which means that nebulizer 1 would need a medication chamber separate (and possibly a separate associated data carrier, such as a medication chamber).
    [0024] In a further embodiment, not shown in Figures 2a-2c, the mesh set 9 may comprise the mesh 9b, the measurement chamber and the data carrier 9a. The data carrier can provide information about the mesh and the dose measured to the nebulizer which information can be used by a clinician, for example, to check for errors. For example, when the total treatment time for a patient is longer than expected, based on the variation in the nebulizer flow and the carrier's data on the dose of the drug and the volume measurement chamber, the doctor you can conclude that the mesh needs to be replaced.
    [0025] Figures 3a to 3c show an additional alternative configuration of a mesh set 9. Figure 3a shows a side elevation of the mesh set 9, comprising data carrier 9a and mesh 9b. Figure 3b shows a final elevation, while Figure 3c shows a sectional view through the X-X section of Figure 3b. According to this specific embodiment, the data carrier 9a is on a different surface than the 9b mesh, which may be desirable in certain applications, for example, to allow the data carrier 9a to be located closer to a data reader 11 corresponding nebulizer. It will be appreciated that various configurations for mounting data carrier 9a and mesh 9b are possible, depending on the specific patent application and the type of nebulizer being used.
    [0026] The data carrier 9a associated with a mesh 9b of a set of mesh 9 contains information pertaining to the mesh 9b, which can be read by the data reader 11 of the nebulizer 1. For example, the data carrier 9a can be used to identify the mesh type 9b being used. Data carrier 9a may contain information about the intended use or validity of mesh 9b, for example, how many times mesh 9b must be used before it is replaced. Preferably, the entire array of mesh 9 (including data carrier 9a and mesh 9b) is replaced after a predetermined number of uses.
    [0027] Alternatively, if data carrier 9a and mesh 9b are detachably connected to the body of mesh set 9, then data carrier 9a and mesh 9b can be replaced independently of the main body of mesh set 9. For example, the user can purchase a data carrier 9a and a mesh 9b which are replaced as a set by fitting a new data carrier 9a and a new fabric 9b to the existing body of the fabric set 9.
    [0028] The information received by the data reader 11 can be used by the nebulizer for various purposes. According to one embodiment, the information received by the data reader 11 can be used to count the number of times that a specific mesh 9b has been used, and then prevent the nebulizer from being operated after the mesh 9b has been used by a number predetermined times. Mesh 9b can therefore be avoided from being used in the drug delivery device when its intended expiration has expired. Alternatively, or, in addition, the nebulizer can be configured to provide some form of indication or warning to the user, once the intended validity has expired, that is, instead of preventing the nebulizer from being used completely. This type of indication or warning encourages the user to replace the mesh, but without preventing the nebulizer from being used.
    [0029] Figure 4 illustrates the steps that can be performed in a mesh nebulizer that has an associated data carrier, as described above in Figures 1 to 3. The steps shown in Figure 4 can be performed as part of the drug delivery operation. , for example, in response to the user causing the drug administration operation. In step 401, the nebulizer reads the data carrier associated with the mesh. In step 403, the nebulizer reads a data field on the data carrier to verify a sum value related to the use of the mesh and determines whether the sum value is equal to a predetermined value. For example, if a specific mesh is intended to be used 255 times and receives a sum value of 255, which is reduced after each use, step 403 may involve checking whether the sum value has reached zero. Alternatively, if the mesh receives a sum value of zero, which is increased after each use, step 403 may involve checking whether the sum value has reached a predetermined value, that is, 255 in this specific example.
    [0030] If it is determined in step 403 that the sum value is not equal to a predetermined value, then in step 405, the sum value is updated (that is, raised or reduced), and the nebulizer operated to administer a drug, step 407 .
    [0031] If it is determined in step 043 that the sum value is equal to a predetermined value, thus indicating that the mesh has been used a predetermined number of times, the nebulizer indicates in step 409 that the mesh needs to be replaced. This may involve disabling the nebulizer so that the mesh can no longer be used.
    [0032] As mentioned above, as an alternative to prevent the nebulizer from being operated after the mesh has been used for a predetermined number of times, the nebulizer can be configured instead of (or, in addition) providing a warning to the user that the mesh must be replaced. For example, the nebulizer can be configured to provide a visual and / or audible warning when it has reached its expected validity.
    [0033] The nebulizer can also be configured to provide such a warning at a predetermined interval before the mesh reaches the end of its validity, thus advising the user to purchase a new mesh.
    [0034] Preferably, the updated sum value shown in step 405 is stored in data carrier 9a associated with mesh 9b. In this way, data reader 11 acts as a data writer in addition to a data reader. In other words, the data reader 11 (for example, an antenna) is adapted to transmit the data to the data carrier 9a, as well as to read the data from the data carrier 9a. In such an embodiment, the data bearer will include, for example, an electrically erasable memory, since it will be apparent to the technician in the subject, such as an Electrically Erasable Programmable Read Only Memory (EEPROM). Other forms of data carriers, capable of storing and updating a sum value, are also intended to be encompassed by the present invention.
    [0035] As an alternative to what was mentioned, the updated sum value can be stored in the nebulizer itself. With such an embodiment, data carrier 9a may have a simpler form of memory device, such as a Read Only Memory (ROM), which is programmed once during manufacture with a corresponding sum value to the intended validity of the mesh. However, the previous method has the advantage of retaining the sum value with the device that is actually being monitored, which provides a more secure application.
    [0036] It is noted that the data carrier 9a and the data reader 11 can be performed in alternative ways using an RFID tag and an antenna. For example, other means of identification, such as a barcode, DX or serial interface, can be used to communicate information between the mesh and the nebulizer. However, using an RFID tag and an antenna has the advantage of not needing any electrical interconnect contacts, which could otherwise be reduced in the type of environment found within a nebulizer device.
    [0037] In addition to data carrier 9a being used to store information related to the use of the corresponding mesh 9b, it is noted that data carrier 9a can also be used to store other information, such as information related to the drug being dispensed. In other words, since data carrier 9a is used to store information about the use of the nebulizer, data carrier 9a can also be used to store other information related to such use, including the number of drug vials to be used. dismissed. Therefore, if a mesh of the nebulizer is replaced at the same time as the drug container, the data carrier 9a of the mesh can be used to indicate when the drug container needs to be replaced. Additionally, as indicated above in Figure 1, if the mesh set 9 forms part of the medication chamber, then data carrier 9a can also store information related to the medication chamber.
    [0038] Figure 5 shows a nebulizer 1, according to another embodiment of the present invention. The nebulizer 1 comprises a body 3 for receiving one or more removable components, such as a mouthpiece 5, a plunger assembly 7 and a mesh assembly 9, As in Figure 1, the mesh assembly 9 forms the medication chamber 13 (although it is noted that these could be separate physical components, without departing from the scope of the invention). The plunger set 7 comprises a medication measurement chamber 15. According to this embodiment, the mesh set 9 comprises a first data carrier 9a, the inlet 5 comprises a second data carrier 5a, and the plunger set 7 comprises a third data carrier 7a. The first data carrier 9a associated with the mesh set 9 also doubles as the data carrier of the medication chamber for that specific accomplishment. Each of the data carriers 5a, 7a and 9a communicates with a data reader 11 mounted on the body 3 of the nebulizer 1.
    [0039] One or more of the removable components 5, 7 or 9 can be a removable component associated with a set of such removable components (i.e., a shape of the interchangeable part selected from a set of such interchangeable parts). For example, the removable mouthpiece 5 can be from a set of different mouthpieces that can be attached to the nebulizer. The nebulizer comprises the control means for controlling the operation of the nebulizer depending on the particular removable component that is attached to the nebulizer at a given time.
    [0040] For example, Figure 6 illustrates the steps that can be performed in a nebulizer depending on the type of mouthpiece attached to the nebulizer. In step 601, the nebulizer reads the data carrier 5a from the mouthpiece 5. In step 603, the nebulizer determines the type of mouthpiece 5 that is fitted to the nebulizer using the information acquired from the data carrier 5a. Then, in step 605, the nebulizer adjusts or controls the operation of the nebulizer, according to which type of nozzle 5 is fitted to the nebulizer.
    [0041] The mouthpiece 5 is part of a set of associated mouthpieces that can be used with the nebulizer, for example, depending on the particular preference of the user, or which is the most suitable for administering a specific type of drug.
    [0042] For example, patients can receive one or more mouthpieces with varying strengths to suit their particular preference, such as a first mouthpiece offering a high strength of approximately 14-18 liters / min., A second mouthpiece offering a low strength of approximately 24-36 liters / min., And a third nozzle providing a resistance of approximately 40 - 60 liters / min. The control software on the nebulizer needs to know which mouthpiece is fitted in order to allow the nebulizer to operate correctly, and the data carrier 5a mounted on the mouthpiece can be used to store such information during manufacture.
    [0043] Figure 7 illustrates the steps that can be performed in a nebulizer depending on the type of medication chamber 13 attached to the nebulizer. In step 701, the nebulizer reads the data carrier from the medication chamber 13 (which would be the data carrier 9a in Figures 1 and 5 due to the medication chamber 13 being formed from the mesh set 9 - a data carrier separated and provided when the medication chamber is formed from the physical entity separated from the mesh set). In step 703, the nebulizer determines the type of medication chamber that is fitted to the nebulizer using the information acquired from data carrier 9a. Then, in step 705, the nebulizer adjusts or controls the operation of the nebulizer, according to which type of medication chamber is attached to the nebulizer.
    [0044] The medication chamber 13 is part of a set of associated medication chambers 13 that can be used with the nebulizer, for example, depending on which particular medication chamber is best suited to administer a specific type of drug.
    [0045] In some patent applications, more than one volume of drug can be administered from the same drug package using different medication chambers. In such patent applications, information about the drug dose in data carrier 9a associated with the 9b mesh may not be sufficient for the nebulizer software to accurately determine the dose of the drug. This is improved by adding a data carrier to the medication chamber 13, as described above (or the gauging system) to the medication chamber 13 to uniquely identify the dose of the drug that has been inserted into the device.
    [0046] The nebulizer can be configured to perform other functions based on the information detected by the data reader 11. For example, the nebulizer can be configured to start a treatment only as soon as a predetermined set of components is detected as being attached to the nebulizer, such as when the mesh set 9, the inlet 5, the plunger set 7 and the medication chamber 13 were detected as being present.
    [0047] Although the realization of Figure 5 shows a single data reader 11 being provided for communication with each of the data carriers 5a, 7a and 9a related to the mouth 5, the plunger set 7 and the set of mesh 9 respectively, it is observed that the nebulizer may comprise one or more data readers 11 for communication with one or more data carriers. According to the realization of Figure 1, data carriers 5a, 7a and 9a can be RFID tags, and data reader (s) 11 can be an antenna, although other forms of communication media are also intended to be encompassed by the present invention.
    [0048] The variation of the RFID system can be configured, so that only the assembled components and their associated data carriers are detected by the data reader (s) 11. This has the advantage that the RFID-labeled components located on the proximity, but not fixed to the nebulizer, are not detected by the data reader (s) 11.
    [0049] This can be achieved by designing and positioning the data reader 11 and the associated data carriers 5a, 7a, 9a, so that the field of operation is limited to the shortest variation required and the positioning of the data carriers close to the data reader. Dice.
    [0050] Figure 8 shows an alternative embodiment, whereby the configuration of the nebulizer is adapted to allow the data carrier 7a associated with the plunger assembly 7 to be brought close to the data reader 11, thereby allowing the variation of the system with RFID is reduced, and thus, reducing the possibility of interference from other devices. According to Figure 5, the nebulizer comprises the mouthpiece 5 with an associated data carrier 5a, a plunger assembly 7 with an associated data carrier 7a and a mesh set 9 with an associated data carrier 9a.
    [0051] The nebulizer described in the above achievements can also adopt one or more other strategies to help reduce or prevent the detection of unwanted items by the radio frequency tag usage system. For example, protection can be provided on the side of the data reader 11 that is opposite the side where the data carriers 5a, 7a and 9a are positioned.
    [0052] In the embodiments described above, data transmission with RFID could be interrupted by an external RF source, such as the piezoelectric element used to vibrate the mesh, or by mobile phones that are within close proximity. However, the former does not have a degrading effect on the operation of the RFID system, since the RFID tags are read normally before the drug administration operation itself, that is, before the piezoelectric circuit is activated, and thus, before such interference is present. The interference from other sources, such as mobile phones, can be overlaid using data correction techniques commonly found in wireless technology, since it will be apparent to the technician on the subject.
    [0053] The RFID system can consist of an integrated circuit with a copper coil, which can be encapsulated in a thin plastic film. This can typically comprise a product that is approximately 10 mm in diameter and approximately 1-2 mm thick. It will be appreciated, however, that other dimensions can also be used depending on the specific nebulizer and without departing from the scope of the invention.
    [0054] The RFID tag can be integrated into a plastic housing mechanically, when filling, or overmolding to produce a hermetically sealed assembly, as shown in Figures 2a to 2c or 3a to 3c. This plastic that houses can also incorporate the necessary mesh for the generation of aerosol, which is typically 10 mm in diameter and 0.025-0.5 mm thick, this can also be mechanically assembled or overmoulded. This generates a set typically 35 x 20 mm and 2-3 mm thick or if the components are assembled coaxially with a diameter of 25 mm and 2-3 mm thick. It will be appreciated, however, that other mounting arrangements and configurations can be used without departing from the scope of the invention.
    [0055] It is noted that data carriers can also be added to other removable components of the nebulizer, such as ID cards or labels.
    [0056] Table 1 below illustrates some parameters of the reader coil and label coils that can be used, for example, in a nebulizer, according to an embodiment of the invention.
    [0057] It is also noted that the RFID tag associated with the mesh can contain several fields related to the mesh and / or the drug and / or the administration system. For example, a "Remaining bottle count" field can be used to determine when the label can no longer be used, as it is reduced each time a treatment is administered.
    [0058] Although the achievements described above have been made in relation to interchangeable mouths, medication chambers or meshes, it will be appreciated that the invention is equally applicable to any other interchangeable part of a drug delivery device, and in particular interchangeable parts of a set of such interchangeable parts.
    [0059] The term "removable component" is intended to cover a part or component of the nebulizer, by which part it contributes to the actual function of the nebulizer, rather than the part that does not work, such as the real drug to be dispensed. In other words, at least part of the removable component is a physical part of the actual nebulizer, which contributes to the physical work of the nebulizer.
    [0060] In addition, while the embodiments of Figures 1 and 5 show a nebulizer with a removable mesh assembly, a removable mouthpiece, a removable plunger assembly and a removable medication chamber, it will be appreciated that not all of these components need necessarily be removable, or be of sets of interchangeable parts. For example, in the realization of Figure 1, the mouthpiece and the medication chamber can be fixed components, instead of removable components.
    [0061] It will be appreciated from what has been said that RFID tags are ideally suited for the described accomplishments, since they do not need electrical contacts that can be affected by saline drugs, generally used in medicated products to be inhaled, that would otherwise be efficient alternative realizations, such as DX or serial interfaces that require electrical contacts. RFID tags are also more suitable than bar codes, since the bottle count can be reduced on the label itself after each treatment, which is safer than reading a bar code and reducing the count on the system itself administration. However, as mentioned above, the invention is not limited to RFID tags only, and that other identification systems can be used without departing from the scope of the invention.
    [0062] It is also observed that the invention can be used with piezo-mesh type nebulizers, in which the piezoelectric element and the mesh are connected, or with piezo-mesh type nebulizers, in which the piezoelectric element and the mesh are formed separately.
    [0063] It should be noted that the achievements mentioned above illustrate rather than limit the invention, and that those skilled in the art will be able to design various alternative embodiments without departing from the scope of the appended claims. The word "comprising" does not exclude the presence of elements or steps other than those listed in the claim, "one" or "one" does not exclude a plurality, and a single processor or other unit may fulfill the functions of several units referred to in the claims. No reference sign in the claims should be interpreted in a way that limits its scope.
