    Field of the Invention
    The present invention relates to a replaceable cap for a dosing device and, more specifically, a replaceable cap for a transdermal liquid dosing device, such as an insulin pen. Background of the Invention
    Insulin-dependent diabetics need to adopt a strict prescribed regimen of injections of liquid insulin in order to manage their diabetes. A popular means of insulin delivery is through a reusable transdermal liquid dosing device commonly called an "insulin pen", which includes a plastic syringe with an insulin reservoir and a cap that covers an end close to the syringe from which insulin is delivered via a hypodermic needle.
    It is known through several published studies that, as diabetics need to ingest several daily insulin injections, the injection procedure becomes routine very quickly, in such a way that an individual dose can be easily overlooked. There is, in general, no simple and reliable way to inform using commonly prescribed insulin pens or examining the injection area - whether a given dose has been administered or not. Missing a prescribed dose of insulin or inadvertently taking excessive doses in a short period of time can create serious health risks and complications in the short and long term for a diabetic person, including hyperglycemia and hypoglycemia.
    Several attempts have been made in the past to solve this problem. For example, Nielsen's US 2009/0076458 describes an injection device that, in itself, is capable of emitting a flashing light signal that indicates the time that has elapsed since the last injection. The blinking light is provided on the device body. Although US tries to solve the same problem as the present invention, it has the disadvantage of forcing a diabetic person to abandon and discard their preferred or prescribed insulin delivery system in favor of a new system, which can be economically prohibitive for many users. Another disadvantage of the injection device described in US is the fact that the user would need to learn the meaning of the flashing light sequence used to indicate the time since the last injection. This can be a significant obstacle for some diabetics, particularly for young people or the elderly.
    US 2004/0062148 from Skyggebjerg describes a stopwatch device that includes two parts of the device that protrude from each other and together form a single portable unit. An insulin pen is provided in one part of the device and the two parts of the device are held together when the pen is not in use. Separating the parts of the device causes a control action to be triggered. This solution suffers from the disadvantage that the preferred realization is complex and requires a little sophistication and discipline from the user when using the device, also requiring the transport of a larger and dedicated separate device. In other described embodiments, one part of the device is integral with a cover adapted to cover a distant part of the first device. The specification is silent on any practical means or advantageous cost for detecting the separation of the device parts in that described embodiment or to ensure adequate cooperation between the cover and the distant part of the first device.
    Systems have been proposed in which medication devices are registered with coupling stations that function as control and indication devices, such as WO 03/063754 and WO 99/43283, of which the latter describes a sleeve-like indicating device that can attached to the rear end of an injection pen. These devices suffer from the disadvantage that an additional piece of equipment needs to be used in conjunction with the insulin pen and are generally complex and expensive.
    US 2002/0096543 describes a portable control device for monitoring doses of insulin delivery. In certain embodiments described, a control device is provided as a separate part that can be attached to a conventional cap of an injection pen and the pen body includes a resonance circuit to allow removal of the cap to be detected. The control device includes a transmitter that communicates with a remote console to remind the patient to take the dosages, and uses a system of colored lights to indicate that a dose should be taken. The achievements described are complex to use and understand, may require the disposal or adaptation of existing preferred or prescribed insulin delivery systems, and are also prohibitively expensive for many users.
    The depositor believes that the disadvantages mentioned above are due, at least partially, to the fact that most insulin pens currently used are not used in conjunction with any means that would assist a user in determining whether a given dose has been administered. Object of the Invention
    It is an object of the present invention to provide a replaceable cap for a transdermal liquid dosing device which will, at least partially, reduce some of the problems mentioned above and which will be relatively cost-effective to manufacture and simple to use. Summary of the Invention
    In accordance with the present invention, a replaceable cap is provided for a transdermal liquid dosing device comprising an elongated hollow body with an open first end that can be replaced on a front part of the dosing device from which the liquid is dosed and a second closed end opposite the first end, in which the cap is releasably received over the dosing device, in which the cap body includes a cavity which opens towards the inside of the cap body and which houses a timer coupled to a key and a timer display unit that displays the time counted by the timer unit on an external surface of the lid body, where the key is closed by the presence of a surface on the front of the metering device when the cover is placed over the metering device and the key is opened when the cover is removed from the metering device, the key release operation does cause the timer unit to restart immediately or after a previously determined period of time, and the time since the timer unit's last reset indicates the time since the dosing device was last used, the replaceable cap is characterized by the fact that the elongated hollow body of the lid includes two main parts that are injection-molded plastic and connect to each other to form the lid, in which the cavity is defined at least partially between the two main parts, and in which the two main parts keep the chronometer unit and the key trapped between them.
    Still other features of the invention are to provide the key in the form of an electromechanical key that protrudes into the inner side of the lid body to cooperate with the outer surface of the liquid metering device; wherein the two main parts are a cap top and a cap bottom which are made of plastic injection molded material; the top of the lid has a window through which the timer display unit is visible; and the bottom of the lid comprises most of the length of the elongated hollow body.
    Still other features of the present invention provide for the cap top to include a flange with a free end that extends towards the first open end and forms a pocket clip.
    Additional features of the present invention provide the second closed end of the lid with a battery compartment provided therein; the battery compartment is formed on the top cover; and the battery compartment has a cover that snaps into place to keep the battery firmly inside. The cover can be color coded to allow its user to fit the cover with a specific dosing device in order to differentiate between different dosing devices. Still other features of the present invention provide the replaceable cover including a removable non-conductive film initially provided between the battery and an associated electrical battery contact, in which the film extends through a groove at the top of the cover to form a projection tongue that it can, before using the cover, be taken by the user to pull the film out of the battery compartment and allow the battery to fit with the contact, so that the film avoids draining the battery before using the cover. The groove can be provided beside the window at the top of the cover and the film initially supplied extending through the cover display unit, such that the film also acts as a protective layer for the timer display unit. The portion of the film covering the timer display unit may also have digits printed on it to mimic the LCD display, such that the user has an indication of what the display will look like when the battery powers the LCD.
    Still other features of the present invention provide the timer unit including an electronic circuit on a printed circuit board (PCB); and the chronometer unit, the chronometer display unit and the key are assembled together as a single control unit that fits into the cavity.
    Additional features of the present invention provide the timer display unit as an inexpensive four-digit digital liquid crystal display (LCD); the chronometer unit counts from zero; the timer is reset to zero by releasing the key and the timer unit is configured to use, during the first 59 minutes and 59 seconds of elapsed time, the first two digits to count the minutes and the last two digits to count the seconds and then use the first two digits to count the hours and the two second digits to count the minutes.
    Still other features of the present invention provide the cavity with a standard size, such that the same control unit can fit in several different covers, in which each cover has dimensions of the internal surface that fit in a specific type of device dosing, and the control unit is capable of being mass produced for all lids with corresponding increase in economies of scale.
    Still other features of the present invention provide the key including a leaf spring that protrudes into the body; the leaf spring is oriented in such a way that it has a fixed end closer to the first open end of the body and a free end closer to the second closed end of the body, such that the act of inserting the front part of the device into the cover cause the leaf spring to flex towards the cavity without the free end hooking to any feature on the front of the device; and the leaf spring is mounted so as to reach an electromechanical key and activate the key when the leaf spring is bent towards the cavity. The leaf spring can be made of spring steel and can have sufficient bending so that differently shaped front parts of different devices fit with the leaf spring sufficiently to activate the key.
    Additional features of the present invention provide for the restart of the timer unit only after the passage of the previously determined time period, and the previously determined time period is five to twelve seconds, in order to prevent the timer unit from being restarted if the the user only quickly removes the cap, as can occur when the user inspects the liquid level in the dosing device or when the user inadvertently removes the cap for a short time.
    Still other features of the present invention provide the selection of the internal dimensions of the replaceable cover body coinciding with the internal dimensions of the existing cover that is initially supplied together with the device, where the replaceable cover provides closure by identical or very similar force or pressure on the existing cap metering device.
    Still other features of the present invention provide the dosing device to be disposable and the replaceable cap also disposable, but capable of being used successively with respect to at least several disposable dosing devices.
    Additional features of the present invention provide the timer display unit including a battery level indicator or warning that provides an indication when the battery is low. The cover can be disposable after the battery is used up, or the battery compartment cover can be removed to allow the user to replace the battery.
    Still other features of the present invention provide the dosing device in the form of an insulin pen that includes a reservoir and a hypodermic needle provided at the front of the device.
    The present invention extends to a replaceable cover for a transdermal liquid dosing device comprising an elongated hollow body with a first open end that can be positioned on a front part of the dosing device from which the liquid is dosed and a second closed end opposite the first end, characterized by the fact that the body has two main injection-molded plastic parts that connect to each other to form the cover body, in which the two parts hold a control unit trapped between them in a cavity defined between the two parts, where the control unit includes a timer unit, a timer display unit that displays the time counted by the timer unit on an external surface of the body, and a key mechanism, in which the key is configured so that it is activated when the cover is placed on the dosing device and / or when the cover is removed from the device dosing oscillator, actuation of the key causes the timer unit to restart immediately or after a previously determined period of time, in which the time since the last restart of the timer unit indicates the time elapsed since the dosing device was used by the last time.

    Detailed Description with Reference to Figures
    Figure 1A shows a perspective view of a replaceable cap (10) according to the present invention and an associated dosing device (12). The lid comprises an elongated hollow body (14) with a first open end (16) and a second closed end (18) opposite the first end. In this embodiment, the dosing device is a disposable insulin pen that includes a reservoir (20) in which liquid insulin is kept, a plunger (22) at a rear end (24) of the insulin pen and a hypodermic needle (not shown) ) from which insulin is dosed at the end of a front part (26) of the insulin pen. The hypodermic needle has a removable cover (28) to cover the needle. Along the body of the insulin pen and beside the front part, one or more transparent sections (30) are provided through which the level of liquid insulin can be checked by visual inspection. The insulin pen can be a previously existing disposable insulin pen commonly available on the market, which is equipped with an existing cap that can be simply discarded and replaced with the replaceable cap in accordance with the present invention.
    The first open end (16) of the lid can be placed on the front (26) of the dosing device, such that the lid fits over the dosing device and covers the front, as shown in Figure 1B, in which the cap is displayed on the dosing device. The cap is releasably retained on the dosing device and has internal dimensions (not shown) dimensioned to fit a specific type of dosing device, where the internal dimensions are selected to match the internal dimensions of the existing lid initially provided with the dosing device, such that the lid according to the present invention provides closure by identical or very similar force or pressure on the existing lid dosing device.
    Figure 2 shows an exploded view of the components of the replaceable cover (10). The replaceable lid includes two main parts, a lid top (40) and a lid bottom (42) that connect to form the lid. The top of the lid and the bottom of the lid are plastic injection molded components and can be connected together by clips, ultrasonic welding, glue or any other appropriate means. The bottom of the lid forms most of the length of the elongated lid body, and the top of the lid has a rectangular shaped window (44) provided inside. A flange (46) extends along an upper side of the top of the lid (40) towards the first open end (16) to form a pocket clip.
    When assembled, a cavity (48) is formed between the top of the lid and the bottom of the lid. The cavity opens into the interior (50) of the cover body and aligns with the window (44). The cavity houses a control unit (52) that fits tightly into the cavity, is kept trapped by the top of the lid and the bottom of the lid and comprises a printed circuit board (PCB) (51) on which a timer unit ( 54), a key mechanism (56) and a timer display unit (58) are mounted. The PCB can be a single layer PCB, in some embodiments, and can be up to 0.5 mm thick. In this embodiment, the timer display unit (58) is an inexpensive four-digit liquid crystal display (LCD) that displays the time counted by the timer unit, and the timer display unit aligns with the window (44), so that it is visible on the top surface of the lid top. The timer display may include a low battery warning indicator and preferably has no backlight to save energy. The timer unit consists of a microcontroller counter and an oscillating crystal and is preferably a microcontroller with a four-bit masked ROM and low voltage (such as 0.9 to 1.7 V) with a built-in LCD driver. A digital clock integrated circuit can also be used for this purpose.
    At the second closed end (18) of the lid, a battery compartment (60) is formed at the top of the lid. The battery compartment is provided at the second end, so that it is as far away as possible from the liquid insulin reservoir of the dosing device, and is formed as a separate compartment to minimize the risk of contamination of the insulin stored in the insulin reservoir of the pen insulin from any leak in the battery. The battery can be a 1.5 V non-rechargeable silver oxide battery that has enough stored charge to power the control unit for a period of at least several months, such as up to more than twelve months and up to 36 months, in that the cap is therefore capable of being used successively with respect to many disposable insulin pens.
    The battery is held in place against a set of electronic contacts (not shown) by means of a cover (64) that clicks into place. The cap is preferably color-coded to allow the user to differentiate between different insulin pens that can be in use at any given time. In some embodiments, the cover is disposable and is intended for disposal after the battery has run out, in which case the cover can be permanently fixed in place by means of glue, ultrasonic welding or deformation of stapling formations. In other embodiments, the cover can be opened by force or unscrewed to replace the battery.
    Figure 3 shows a top plan view of the replaceable cover (10) and the dosing device (12) with the cover on the dosing device and Figure 4 shows an elevation in section along line AA in Figure 3. As shown in In figure 4, the key mechanism includes a leaf spring (70) that partially extends out of the cavity in which the control unit (52) is mounted and protrudes into the interior (50) of the cover body. The leaf spring is oriented in such a way that it has a fixed end (72) closest to the first open end (16) of the cover body and a free end (74) closest to the second closed end (18) of the body. The leaf spring is mounted so as to contact an electromechanical key (76) on the PCB to activate the key when the leaf spring is bent towards the cavity. The act of inserting the front part (26) of the insulin pen (12) into the open end of the cap causes the surface of the front part to contact the leaf spring and cause it to flex towards the cavity and pressure of the key (7 6). As the leaf spring is oriented with its free end closer to the closed end of the body, the free end does not engage in any detail, such as protrusions or shoulders, that may be present on the front part (26) of the dosing, as could happen if the leaf spring were oriented in the opposite direction. The leaf spring is preferably made of spring steel and has sufficient flexion so that all the front parts with different shapes of different insulin pens fit with the leaf spring sufficiently to activate the key.
    Importantly, the cavity (50) in which the control unit (52) fits is selected as being of standard size, in such a way that the same control unit can fit in several different covers according to the present invention, in which each cap has internal surface dimensions such as to fit a specific type of dosing device. Preferably, the dimensions of the inner surface of each type of cap are selected to match the dimensions of the inner surface of the existing cap that is initially supplied in conjunction with that type of insulin pen, and the replaceable cap according to the present invention provides identical or very similar to the existing cap supplied with the pen. Having the standard size cavity allows the same control unit to fit each different type of cover, where the control unit is capable of mass production with the consequent increase in economies of scale. It is also important in this regard that, as mentioned earlier, the leaf spring has sufficient flexion so that all the front parts with a different shape from different insulin pens fit the leaf spring sufficiently to activate the key. The same switch mechanism can be used, therefore, in all control units.
    As also shown in Figure 4, a removable non-conductive film (78) is provided between the battery (80) and one of its associated electrical contacts (not shown). The non-conductive film extends through a groove (84) which is provided next to the window at the top of the lid, and extends through the timer display unit (58) and ends at a projection tongue (86) . The removable non-conductive film will be placed in place during manufacture and is intended to remain in place until the actual use of the cover by a patient. When a patient is ready to use the cap, the tab is held between the thumb and forefingers and the film is pulled out of the timer display and out of the battery compartment, causing the battery to engage with the electrical contacts. The film therefore avoids the waste of the battery before use, greatly increasing the service life of the replaceable cover according to the present invention. The portion of the film covering the timer display unit may also have digits printed on it to mimic the LCD display, such that the user has an indication of what the display will look like when the battery powers the LCD.
    During use, the electromechanical key (76) is activated when the cap is fully inserted over the insulin pen and the key is released when the cap is removed from the insulin pen. Inserting or releasing the key causes the timer unit to restart after the passage of a previously determined period of time, which is preferably five to twelve seconds, preferably more than about eight seconds. After the timer is restarted, the timer display unit resets the LCD to zero, after which the timer unit starts to display the time that has elapsed since the timer was last reset. In this way, the replaceable cap according to the present invention indicates to a patient the time that has passed since the insulin pen was last used.
    The reason why the timer is preferably not restarted immediately by inserting or releasing the key is the fact that users of insulin pens sometimes quickly remove the cap from the insulin pen to merely check the levels of liquid insulin through the sections. transparent (30), without insulin injection. This action typically takes just two or three seconds, while the insulin injection action typically takes at least twelve seconds. In addition, the user may inadvertently remove or partially remove the cap for a short period, just as when dealing with pens or other devices. Therefore, it is considered that, if the cap has been removed for a longer time than previously determined, the user has taken a prescribed dose of insulin and the timer is restarted. In this way, simply observing the display unit of the digital timer, the patient can confirm the time that has elapsed since the last dose took place, in order to avoid the anxiety of imagining whether the previous dose has been forgotten or if the previous dose has just been taken and reduce the risk of accidental overdosing or underdosing.
    In the preferred embodiment, the four-digit LCD counts upward from zero and uses the first two digits to count the minutes and the last two digits to count the seconds during the first 59 minutes and 59 seconds after the last time the timer has been reset. When the timer reaches sixty minutes, the first two digits are used to count the hours and the second two digits are used to count the minutes. In this way, it is possible to use only a four-digit LCD instead of a more expensive six-digit LCD, still being able to indicate the seconds to the user during the first hour after the last dose of insulin.
    Figure 5 is a state diagram showing the states in which the control unit may be. When packed, the control unit is in a packed condition (100), during which nothing is displayed on the LCD, as the battery is disconnected. After removing the film, the control unit enters a reset state (102) during which the timer is reset and maintained at zero and all segments of the LCD flash. The pressure of the key, as occurs when the key is placed on the insulin pen for the first time, causes the control unit to enter a "cap placed" state (104) during which the timer runs and the time of operation is displayed on the LCD. During the "cap placed" state, the four-digit timer will use the first two digits for the minutes and the last two digits for the seconds during the first 59 minutes and 59 seconds of elapsed time and therefore uses the first two digits for the hours and the last two digits for the minutes, as explained above. The timer can be configured to count up to 99 hours and 59 minutes. If the key is released after the "capped" state, as when the cover is removed, the control unit enters an intermediate state (106). During the intermediate state, the timer continues to run for a previously determined period, which can be, for example, eight seconds. If the key is pressed again before the end of the previously determined period (as if the cover is quickly replaced after removal), the control unit enters the "with cover" state (104) again. If, however, the cover is not replaced within the previously determined period, the control unit enters the reset state (102) and the timer is restarted and maintained at zero with all segments of the LCD flashing as previously described.
    The present invention provides a simple, cost-effective replaceable cap for a dosing device by which a patient can confirm the time that has elapsed since the last dosing took place. The present invention does not require a user to carry any additional equipment, as the cap simply replaces the existing cap that is provided with the dosing device. No special instructions need to be followed, no timing scheme using flashing lights or other non-numeric indicators needs to be learned and memorized and no change in the procedure for using the dosing device needs to be performed by the patient. The slap can be easily used by anyone familiar with a digital watch, which should include the very young and the very fragile. In addition, as the internal dimensions of the replaceable cover are selected to coincide with the internal dimensions of the original cover that is replaced, the cover according to the present invention has the same feeling of closing by force or pressure as the original cover, and the key does not interfere in any way with the security with which the cover fits the dosing device. The top of the lid and the bottom of the lid can be made by means of basic two-part injection molding and, since no moving part needs to be molded into the lid, the lid can therefore be shaped very cost-effectively. As the cavity into which the control unit is fitted is standard across all different types of covers, control units can be mass produced, which further reduces the cost of covers.
    Although the present invention has been described with reference to specific embodiments, it will be appreciated that the present invention is not limited to the described embodiment and that variations can be made without departing from the scope of the present invention. The key does not, for example, need to include a leaf spring, but it may include a dome wrench or a conductive elastomeric wrench. In other embodiments, a capacitive sensor can detect the presence of the front part of the insulin pen without the need for physical contact or a moving part, which would facilitate the sealing of electronic components. An optical sensor could also be used by reflecting a beam from an internal surface of the lid that would be interrupted by the insulin pen or detection of ambient light. The replaceable cap according to the present invention can be used with other types of dosing devices, such as epinephrine autoinjectors, antiretroviral pens or other dosing devices that make use of a replaceable cap. The timer unit does not need to count upwards, but it can count downwards, in order to indicate the time remaining until the next dosage.
