    PATIENT INTERFACE DEVICE FOR ADMINISTER A RESPIRATORY GAS FLOW TO A PATIENT HAVING A FACE, NOSE AND TWO NOSES
    CROSS REFERENCE TO RELATED APPLICATIONS 5 This patent application claims priority benefit under 35 USC Paragraph 119 (e) of North American Provisional Application No. 61 / 263,428 filed on November 23, 2009, the contents of which are hereby incorporated by reference .
    10 HISTORY OF THE INVENTION
    FIELD OF THE INVENTION This concept disclosed relates to patient interface devices and, in particular, to a patient interface device including a single side nasal component to selectively seal only one of the two nostrils of the patient's nose.
    DESCRIPTION OF THE RELATED TECHNIQUE There are several situations where it is necessary or desirable to administer a flow of respiratory gas non-invasively to a patient's airway, that is, without intubating the patient or surgically inserting a tracheal tube into his esophagus. For example, it is known that ventilating a patient using a technique known as non-invasive ventilation. It is also known to administer continuous positive airway pressure (CPAP) or variable airway pressure, which varies with the patient's breathing cycle, to treat a medical condition such as airway resistance syndrome. upper airway resistance (UARS), congestive heart failure and sleep disordered breathing (SDB), such as snoring, epic and sleep apnea syndrome, in particular obstructive sleep apnea (OSA - obstructive sleep apnea).
    Non-invasive ventilation and pressure support therapies involve placing a patient interface device including a mask component on a patient's face. The mask component can be, for example, and among others, a nasal mask that covers the patient's nose, an open interface such as a nasal pillow or cannula having a nasal catheter that is received inside the patient's nostrils, a nasal mask / oral covering the nose and mouth, or a full face mask covering the patient's face. The patient interface device relates a flow generator, such as a ventilator or pressure support device, to the patient's airway, so that a flow of respiratory gas can be administered from the pressure / flow generating device to the airway. patient. A common complaint about patient interface devices is that the mask component is restricted, claustrophobic and / or intrusive to the user. Open interfaces such as, for example, and among others, nasal cannula and various nasal pads, are typically smaller and thus less intrusive. However, the disadvantages associated with such open interfaces include the fact that the airflow can be uncomfortably cold, and can dry out the patient's nasal passages and sinuses. In addition, the open interfaces do not pressurize the upper airway passages like the pressure-controlled sealed interface.
    SUMMARY OF THE INVENTION In one embodiment, a patient interface device is provided and includes a structured coupling for receiving and distributing a flow of respiratory gas, and a nasal component extending out of the coupling, the nasal component including a single element of structured seal to hold and seal only one of the two nostrils of a patient's nose.
    In a particular embodiment, the patient interface device may further include a structured assembly device for securing the patient interface device in a desired orientation with respect to the patient's nose. The mounting apparatus may include a strip, and
    The coupling may include a securing part, where the strip is attached to the securing part. The fixation part may include a first extension and a second extension, in which the first extension extends laterally out of the coupling for fixing one of the corresponding strips on one side of the patient's face, and in which the second extension extends laterally for Eora of the coupling to fix 15 of the corresponding bands on the other side of the patient's face. A method for fitting a patient interface device is also provided. The method includes receiving the patient interface device, wherein the patient interface device includes: (i) a coupling for receiving and distributing a flow of respiratory gas; and (ii) a nasal component that extends towards the Eora of the coupling, the nasal component including a single sealing element. The method further includes securing and sealing a patient's single nostril 25 with the only sealing element. The patient interface device may also include at least one channel and the method may include the step of coupling the channel to the patient interface device coupling to administer the flow of respiratory gas from a flow generator to the device interface device. patient. Preferably, the nasal component of the patient interface device is rotatably coupled to the patient interface device coupling.

    DETAILED DESCRIPTION OF THE EXEMPLARY ACHIEVEMENTS 5 Figure 1 shows the patient interface device 2 according to a non-limiting realization of the revealed concept. The patient interface device 2 includes a coupling component 4 (referred to herein as simply a "coupling") and a nasal component 6 that extends out of it. The nasal component 6 includes a single sealing element 8, which may comprise, for example, and among others, a nasal pad, a nasal insert, a cannula, a nasal mask or any other suitable or known alternative apparatus to provide a sealed interface suitable with a respiratory tract (e.g. nasal passage, nostril) of a patient 300. When patient interface 2 is employed, the only sealing element 8 secures and seals only nostril 1-06 of the two nostrils 1-06, 108 of the patient's nose 104 as shown. The patient interface 2 also includes at least one channel 10 (partly shown in the phantom line in figure 1; also shows channel 110 partially shown in the solid line drawing in figures 3 and 4, and channel 210 in figure 5) for administration. a flow of respiratory gas (usually indicated by the arrow 100 shown in the phantom line drawing in figure 1) from a flow generator 400 (shown in the simplified form in figure 1) in coupling 4 of the patient interface device 2 which, in turn, instead, it receives and selectively distributes the respiratory gas flow 100 in a single nostril 306 of the patient's nose 304. In this way, the patient interface device 2 overcomes the disadvantages of known patient interface devices (for example, among others) , open interfaces, such as a cannula, and closed interfaces, such as a urinary CPAP mask). That is, the patient interface device 2, and in particular the single-sided nasal component 5 thereof, allows the other nostril 308 of the patient's nose 304 to be unobstructed for exhalation and free inhalation, for example, of the surrounding air. . Certainly, the single-sided nasal component 6 allows the patient's nasal sinus cavities 300 to be reheated and moistened, thus improving patient comfort 300 while receiving ventilation therapy. As an added benefit, the patient interface device 2 also reduces audible noise, such as noise caused by patient 300 breathing against air pressure or flow when exhaling.
    It will be appreciated that the concept disclosed to selectively seal only a single nostril 306 from the patient's nose 304 can be employed with any known or suitable type and / or configuration of the patient interface device other than those shown and described here. It will also be noted that the revealed concept can be used in combination with a wide variety of additional or alternative functions to provide any known or suitable type of ventilation support (eg, among others, pressure support) to the patient's desired airway 300 For example, and among others, in the example of figure 1, the nasal component 6 is rotatably coupled to the coupling 4, although such a function is not necessary. Similarly, coupling 4 is shown to include exhalation port 34 in figure 1. However, such an exhalation port 34 is not required, or may alternatively or additionally, be arranged on nasal component 6 or another suitable location on the device of the patient interface
    2. In addition, exhalation port 34 can have any of a variety of configurations, including those found on existing patient interface devices.
    Other elements, such as filters, doors, sensors and any other conventional elements used or for use with
    5 patient interface devices can be used with the patient interface device 2. Continuing to refer to figure 1, it will be noted that the patient interface device 2 still includes a mounting device 12 such as, for example and among others , an adjustable head band 14 and an adjustable axis band 16, which are shown to secure the patient interface device 2 in a desired orientation with respect to the nose
    304 of patient 300. As best shown in figure 2 of the device of the patient interface 2, the exerciser includes a fixation part 18 having a first extension 22 and a second extension 24. The first extension 22 extends laterally out of the coupling 4 for fixation from one of the corresponding bands 14,16 on one side of the patient's face 302, and the second extension 24 extends laterally outward to the coupling 4 in the opposite direction for fixing the corresponding bands 14,16 on the other side of the patient's face 302. In the example in figure 1, the first extension 22 and the second extension 24 include the first compartments
    26, 30 respectively, to receive corresponding parts of the adjustable headband 14, and second compartments 28,32, respectively, to receive corresponding parts of the adjustable shaft band 16. However, it will be noted that any alternative number, type and / or configuration adequate or known assembly device 12 could be employed, without departing from the scope of the revealed concept. see, for example, the patient interface device shown in figures 1-2 is shown in U.S. patent application no. 11 / 811.126 (publication no. 2008/0149105), the contents of which are incorporated by reference.
    For example, and among others, figures 3-5, respectively, show two alternative non-limiting embodiments of the patient interface device according to the principles of the present invention. In particular, the embodiments of figures 3-5 illustrate the minimum that the structure of the patient interface device 102 (figures 3 and 4), 202 (figure 5) can be. Thus, it will be observed that according to the revealed concept, an effective pressure or flow interface is provided with a minimally invasive or intrusive form. In addition, patient comfort is enhanced in that one of the patient's nostrils 308 remains free and thus free to inhale and exhale to keep the patient's sinus cavities warm and moist. In the example of figures 3 and 4, the patient interface device 102 includes a coupling 104 and nasal component 6, which extends out of it and includes a single sealing element 108. The single sealing element 108 secures and seals the single corresponding nostril 306 of patient's nose 304. Channel 110 is structured to be coupled to coupling 104 to provide fluid communication with the flow generator (not shown, but see flow generator 400, shown in simplified form in figure 1) . The assembly device 112 of the patient interface device 102 includes a head band 114, which is suitably attached to the coupling 104 in the fixing parts 118 and 120. It will be noted that while the only exemplary sealing element 108 is shown as the pad nasal or cushion than any other known or suitable sealing element (eg, but not limited to, nasal insertion; cannula; nostrils - external mask envelope) or method (eg, adhesives; suction; pressure against a flexible member) could be employed, without leaving the scope of the revealed concept. In the example of figure 5, the patient interface device 204 includes an even more minimalistic design (for example, compact; non-intrusive) in which a channel 210 5 extends out of a coupling 204 and is secured by the fixing parts 218 , 220 (for example, among others, bands; loops) of head band 14 of the mounting apparatus
    12. In this way, channel 210 extends along the adjacent face of side strip 214 adjacent to the patient's face
    302. The nasal component 206, and in particular the single sealing element 208 thereof, extends out of the coupling 4 to secure and seal only a corresponding nostril 306 of the patient's nose 304. It will be noted that the only sealing element 208 , the nasal component 206, the coupling 204 and / or channel 210, or any combination thereof, may, although not necessarily, comprise a single continuous piece of the appropriate material (for example, among others, plastic, silicone, gel or rubber) .
    Now with reference to figure 6, a device of the patient interface 400 according to another embodiment of the present invention is shown. More specifically, in this exemplary embodiment, the patient interface 400 includes a coupling component 404 and a nasal corriponent 406, in which a valve element 408 is provided in the coupling components. The valve element 408 is a one-way valve having a valve flap 410 that selectively opens and closes the opening 412 as indicated by arrow 414. The valve flap 410 is coupled to the coupling component 404 in any suitable form of forage that is tilted in the closed position during exhalation and is open during at least part of the inhalation phase of the respiratory cycle. A hinge spring, for example, can be used to couple valve flap 410 to coupling component 404.
    In use, valve element 408 opens to the atmosphere using inspiration so that the user receives a gas flow from the gas supply 5 through the 10O channel, as indicated by arrow 416 and the gas supply entering the device from the patient interface through valve element 408, as indicated by arrow 418. This configuration is useful in situations where the use cannot receive an adequate gas supply from the gas supply alone. Suppose, for example, that a user is receiving a fixed gas flow rate 416 in his left nostril and the rest of the gas he / she needs during each breath from the right nostril under normal conditions. Suppose, then, that the right nostril is blocked, which may be due to nasal congestion, allergies and / or external forces, such as a pillow or mattress pushing or blocking the right nostril. In this situation, the user may attempt or wish to inhale more gas than is being provided by gas flow 416 alone. In this case, the flap of valve 410 would open during inhalation, due to the reduced pressure within the part of the coupling 404 with respect to ambient atmospheric pressure, thus allowing a flow of secondary gas 418 to be provided to the user's left nostril. While a single valve element is shown in figure 6 having the single flap configuration, it should be understood that the present invention provides for additional valve elements. In addition, the valve element may have other configurations, such as a butterfly valve, a ball valve etc. Finally, the valve element can be provided at other locations in the patient interface device and / or in channel 10 so as to allow additional gas flow in the patient interface device when the gas flow 4.16 is not sufficient to meet with the patient's demand. It is to be understood that the valve element 408 can be provided in the exhaust port 34. Figures 7A and 7B illustrate another embodiment of a patient interface device 420 according to the 5 principles of the present invention. In this embodiment, the patient interface device 420 is reversible with respect to its placement on the user so that the user can select which nostril is sealed by the nasal component 406 depending on the orientation of the patient interface device. In other words, the patient interface device 420 is configured to be placed on the user to seal the left nostril (figure 7A) when placed on the patient in a first position, or to seal the right nostril (figure 7B) when placed on the patient in a second position, which is inverted, "folded" or mirrored from the first position. That is, when a first side of the patient interface device 420 faces a patient as shown in figure 7A, nasal component 406 seals the left nostril. When the device's interface
    20. Patient 420 is folded and used in another way, nasal component 406 secures and seals the right nostril, with the first side 408 of the patient interface device now away from such a patient. Thus, it can be seen that this embodiment of the present invention allows the user to select which nostril to seal and thus merely change how he / she wears the patient interface device. Certainly, suitable head guard couplings should be provided on the patient interface device to allow the user to choose any orientation for using the patient interface device.
    Figures 8A and 8B show a patient interface device 440 in accordance with yet another embodiment of the present invention that also provides the ability to select which nostril to attach and seal. In this embodiment, the user does not need to change the orientation of the patient interface device as in the realization of figures 7A and 7B, 5 but instead changes the physical configuration of the patient interface device. For this purpose, the patient interface device 440 includes a first port 450 and a second port 452 provided on coupling 444. In a first configuration shown in figure 8A, which is used to seal the first nostril, a nasal component 446 is selectively coupled to the first port 450 and the second port 452 is blocked via a plug 454. In a second configuration, shown in figure 8B, which is used to seal the second nostril, the nasal component 446 selectively coupled to the second port 452 and the first port 450 is blocked with plug 454. This embodiment of the present invention allows the user to adjust or configure the patient interface device 44.0 so that the nasal component grips and seals the nostril of his choice.
    While figures 8A and 8B illustrate an exemplary technique and configuration for the doors, the plug and the nasal component, it can be seen that the present invention observes a wide variety of techniques and configurations for these components. For example, the plug and the nasal component can be formed from a unitary structure that is inverted or turned to provide two different configurations. As shown in figure 9, the present invention further notes that coupling 444 may include a single port 460 defined on coupling 464, with a single nasal component 462 being adapted to be selectively disposed on port 460. When nasal component 462 is asymmetric that when the nasal component is arranged on port 460 in the first configuration, the component
    14/15 nasal seals the first nostril, and when the nasal component 462 is folded or inverted, as indicated by the arrow 464, so that it is disposed in the second configuration, the nasal component 4 seals the second nostril.
    5 While only a few different possible techniques have been revealed to alter the position of the nasal component so that the user can select which nostril to seal, it should be understood that the present invention observes a wide variety of other techniques to control or change the position of the nasal component to provide this user with selectivity. For example, channel 10 can be selectively fixable on either side of the coupling part with the other side being blocked to change the orientation of the nasal component.
    Figure 10 illustrates yet another embodiment of the present invention. In this embodiment, the patient interface device 470 includes a coupling component 474 and a nasal component 476, and a stabilizing component
    478. The nasal component 476 serves the function of the nasal components discussed above, that is, to attach a seal to one of the user's nostrils. The stabilizing component 478 attaches to the other nostril, but still serves the purpose of providing a stable patient interface on the face and user; and does not seal, that is, it does not communicate with a flow of gas carried through channel 10 to a user's airway. Instead, the stabilizing component 478 is opened to the atmosphere, for example, providing an exhaust outlet or door
    480. The gas charged through channel 10 does not enter the stabilizing component 478, for example, there is a wall or other physical barrier between each side of the coupling component
    474. Port 480 can have any configuration, size, shape and location, as long as it provides communication of the stabilizing component 478 to the ambient atmosphere. The present invention further notes that port 480 can be configured and arranged to suit any desired structural and flow characteristics. For example, in one embodiment, port 480 is configured and arranged to reduce flow resistance, thus providing relatively open communication between the nostrils of the
    The user and the ambient atmosphere. Although the revealed concept has been described in detail 10 for the purpose of illustration based on what is currently considered to be the preferred and most practical achievements, it should be understood that such details are for this purpose only and that the invention is not limited to the disclosed achievements , but, on the contrary, it aims to cover the 15 modifications and equivalent provisions that are within the spirit and scope of the attached claims. For example, it should be understood that the present invention notes that, to the extent possible, one or more functions of any embodiment can be combined with one or more functions of any other embodiment.
