Description

Technical Field

[0001] The present invention relates to a mask bulge for a patient interface, the mask bulge being used optionally with a hose between the mask bulge and the patient's face. Background Technology

[0002] In some cases, patients receiving artificial respiration or requiring assisted breathing also require a nasogastric tube to ensure the supply of nutrients, fluids, or medications. The nasogastric tube is typically administered via a soft tube through the mouth or nose. In the case of a conventional breathing mask, significant leakage occurs when the soft tube is guided between the mask and the patient's face. This leakage can usually be reduced only slightly by pressing the mask more firmly against the patient's face; however, this creates a pressure point and results in an uncomfortable mask-wearing experience.

[0003] To improve mask fit when using a nasogastric tube simultaneously, different solutions exist in the prior art. One solution describes a tubing guide within the mask body. While this solution achieves a good mask seal, it does not allow for mask or tubing replacement or removal without the corresponding other parts being removed for extended periods. Another solution describes a separate pad for the tubing, positioned between the mask and the patient's face. This pad can be quickly perceived as a foreign object and hinders optimal, comfortable mask placement. While a notch in a thin sheet within a notch in the lateral region of the mask pad provides improved sealing during tubing use, additional leakage occurs after tubing removal. Summary of the Invention

[0004] The objective of this invention is to provide a mask protrusion for a patient interface that allows for easy replacement or removal of the patient interface or tubing, while providing an optimal seal and comfortable wearing. This objective is achieved through the mask protrusion of the preferred embodiment of this invention.

[0019] In some embodiments of the mask bulge, the segment has at least one end facing the central opening and an end facing the transition region.

[0020] In some embodiments of the face mask bulge, the ends of the segment are rounded. In some embodiments of the face mask bulge, the ends of the segment are semi-circular.

[0021] In some embodiments of the mask bulge, the notch opens toward the center opening.

[0022] In some embodiments of the mask bulge, the endpoints of the notch pointing towards the opening are spaced apart from each other.

[0023] In some embodiments of the mask bulge, the sides of the notch do not contact each other in the end region.

[0024] In some embodiments of the mask bulge, the segmented construction is designed to be placed on a hose and at least partially conforms to the shape of the hose.

[0025] In some embodiments of the mask bulge, the support lip has a bridge nasal region, two lateral regions, and a base region, wherein the support lip extends from the lateral regions toward a central opening and is not connected to each other in the bridge nasal region and the base region.

[0026] In some embodiments of the mask bulge, the support lips extend from the lateral region and from the bridge of the nose toward the central opening and are not connected to each other in the region of the base region.

[0032] It is shown that the features listed individually in the preferred technical solutions can be combined with each other in any technically meaningful way to propose other configurations of the invention. The specification and the invention are characterized and described in detail, particularly in conjunction with the accompanying drawings.

[0033] Furthermore, it should be noted that the conjunction “and / or” used herein, referring to the existence of two features and their relation to each other, always means that in the first configuration of the subject matter according to the invention, only the first feature may exist, in the second configuration, only the second feature may exist, and in the third configuration, not only the first feature but also the second feature may exist.

[0034] A respiratory device is understood to be a device that assists a user or patient in natural breathing, performs artificial respiration on a user or patient, and / or is used for respiratory therapy and / or otherwise affects the breathing of a user or patient. However, a respiratory device is not limited to, for example, CPAP devices and BiPAP devices, anesthesia devices, respiratory therapy devices, (hospital, outpatient, or emergency) respiratory devices, high-flow therapy devices, and cough suppressants. A respiratory device can also be understood as a diagnostic device used for artificial respiration. Diagnostic devices can be used here to detect a patient's medical parameters. A respiratory device is also a device that can detect and optionally process a patient's medical parameters related to or solely with breathing.

[0035] The patient interface can be understood as any part of a respiratory apparatus, or any peripheral device connected to it, that is not explicitly described elsewhere, and is considered for interaction with the patient, particularly for therapeutic or diagnostic purposes. The patient interface can be understood in particular as the face mask of the respiratory apparatus or a face mask connected to the respiratory apparatus. The face mask can be a full-face mask (enclosing the nose and mouth), a total-face mask (enclosing at least the nose, mouth, and eyes), a breathing mask, or a nasal mask (enclosing only the nose). Trachea and so-called nose supports can also be used as face masks. Attached Figure Description

[0054] Figure 1 An exemplary embodiment of the mask bulge 1 is shown in a three-dimensional front view. A lip 14 extends in the mask bulge from a transition region 21 toward a central opening 15, the transition region being exemplarily implemented here as a mask body connector 211, the central opening being completely surrounded by the lip 14. The surface 141 of the lip 14 is configured as a contact surface with the user's facial skin 4 and, particularly, seals tightly against the facial skin when the tube 3 between the mask bulge 1 and the facial skin 4 is not used. Exemplarily, Figure 1The embodiment shown is constructed for connection to the mask body of a patient interface 2, for example, implemented in multiple parts, and for this purpose has a transition region 21 configured as a mask body connector 211. In some embodiments, the patient interface 2 is also implemented as a single piece, that is, the mask protrusion 1 and the mask body are components made of, for example, a single material. In the case of a single-piece patient interface 2, the transition region 21 is, for example, a smooth transition between the mask protrusion 2 and the mask body. The single-piece patient interface 2 can be manufactured, for example, by the 2K method and / or by injection molding. In some embodiments, the transition region 21 is implemented with a greater material thickness and greater rigidity than the lip 14. The lip 14 can be implemented, for example, as a combination of a support lip 143 and a sealing lip 142. The two functions of support (support lip 143) and sealing (sealing lip 142) can also be distributed across two or more lips.

[0055] Figure 2 An exemplary embodiment of a mask bulge with two lips 14 is shown. Here, the outer lip 14 is implemented as a sealing lip 142. The inner lip of the two lips is configured as a support lip 143 and also has a section 16 configured to guide the hose 3. The sealing lip 142 extends from the transition region 21, which is implemented as a mask body connector 211, toward the central opening 15 and completely surrounds the central opening. The support lip 143 also extends substantially from the transition region 21 to the central opening 15 and at least partially surrounds the central opening.

[0056] The support lip 143 has, for example, a greater material thickness than the sealing lip 142. The support lip 143 is also stronger or more rigid (e.g., a result of the greater material thickness) to support the mask bulge 1 or patient interface 2 relative to the user's face. The sealing lip 142 has, for example, a substantially smaller material thickness than the support lip 143 and can flexibly conform to the user's face. The sealing lip 142 is used to initially seal the mask bulge 1 onto the user's facial skin 4. In some embodiments, the material thickness of the sealing lip 142 and / or the support lip 143 may also gradually decrease and / or increase from the transition region 21 toward the central opening. This can result in the sealing lip 142 having a segmental greater material thickness than the support lip 143. That is, the area of ​​the sealing lip 142 with a larger material thickness (e.g., adjacent to the transition region 21) may therefore have a larger material thickness compared to the area of ​​the support lip 143 with a smaller material thickness (e.g., adjacent to the central opening 15). In particular, in embodiments of the mask protrusion 1 having only one lip 14, which is constructed as a combination of a sealing lip 142 and a supporting lip 143, the lip 14 can be varied in terms of material thickness in sections. In particular, the sealing lip 142 can have a particularly small material thickness in the area of ​​the supporting surface on the user's facial skin 4, which, for example, allows for easy matching with the unevenness of the user's face.

[0057] exist Figure 2 The diagram continues to show the bridge of the nose region 11, the lateral region 12, and the base region 13. The bridge of the nose region 11 is the region on which the user's nose rests. The lateral region 12 is located not only to the left but also to the right of the base region 13 and the bridge of the nose region 11; the designation of the second lateral region 12 is not shown for simplicity. The lateral region 12 of the supporting lip 143 is located in the base region 13. Figure 2 The areas shown are not connected or at least partially connected. That is, the support lip, unlike the sealing lip 142, does not completely surround the central opening 15. The transition from the lip 14 to the transition region 21 can be easily seen at the interruption in the base region 13 of the support lip 143. In particular, in a patient interface 2 made of a single part, a smooth transition can be formed at this location, such that the material thickness gradually increases, for example, from the lip 14 to the transition region 21. In some embodiments, it is conceivable that the sealing lip 142 and the support lip 143 extend at least partially as a single lip 14 from the transition region 21 toward the central opening 15 and are separated into separate sealing lips 142 and support lips 143 between the transition region 21 and the central opening 15.

[0058] In some embodiments, the lateral regions 12 of the support lip 143 are also not connected in the bridge of the nose region 11, so that the support lip 143 is constructed only in the lateral regions 12 and at most partially in the base region 13 and / or the bridge of the nose region 11. In some embodiments, the lateral regions 12 of the support lip 143 are also not connected only in the bridge of the nose region 11. In some embodiments, the lateral regions 12 of the support lip 143 are also at least partially connected in the bridge of the nose region 11 and / or the base region 13. For example, the lateral regions 12 toward the central opening 15 may not be connected, while the lateral regions 12 of the support lip 143 toward the transition region 21 are connected to each other. A small material thickness of the support lip 143 in the bridge of the nose region 11 and / or the base region 13 may also be considered.

[0059] In some exemplary embodiments, the sealing lip 142 has a smaller material thickness in the bridge of the nose region 11 compared to other regions. The material thickness is also partially smaller in the base region 13 of the sealing lip 142. In some cases, the base region 13 and the bridge of the nose region 11 have the same material thickness, which is, for example, less than the material thickness in the lateral region 12 of the sealing lip 142. In some embodiments, the material thickness of the sealing lip 142 gradually decreases from the lateral region 12 to the base region 13 and / or the bridge of the nose region 11. In some embodiments, the sealing lip 142 and / or the support lip 143, also presented as a single lip 14, may additionally have a support structure.

[0060] Figure 2 The mask bulge 1 shown has a section 16 in the lateral region 12 of the support lip 143, which is configured for guiding a flexible tube 3 that can be disposed between the mask bulge 1 and the user's facial skin 4. If the flexible tube 3 is not disposed between the mask bulge 1 and the user's facial skin 4, the lip 14 (in embodiments with two lips 14, initially a sealing lip 142) seals the mask bulge 1 against the facial skin 4. It is entirely possible that, for example, in cases of incorrect bearing or incorrect sizing of the patient interface 2 or the mask bulge 1, the support lip 143 may also at least partially rest against and / or contact the user's facial skin 4.

[0061] In other words, the mask bulge 1 with section 16 is considered as a mask bulge for use with a flexible tube 3, for example, for a gastric tube or similar tube. Furthermore, however, the mask bulge 1 can also be used without the flexible tube 3, without having an uncomfortable support or small seal relative to the mask constructed solely for use without the flexible tube 3. The mask bulge 1 shown is exemplarily illustrated as a mask bulge for a face mask for non-invasive artificial respiration; however, some of the technical features can also be used for other mask types, such as for nasal masks or other breathing masks.

[0062] When the tube 3 is positioned between the facial skin 4 and the sealing lip 142 of the mask bulge 1, the tube 3 extends below or along the section 16, which rests on and / or surrounds the tube 3. Here, the sealing lip 142 located between the section and the tube is deformed by the tube 3 such that the sealing lip 142 extends on the tube 3, at least partially covering and thus largely sealing the tube. This minimizes leakage, particularly compared to a mask bulge without the section 16 considered for guiding the tube. (From...) Figure 2 In an exemplary embodiment, section 16 is implemented as a notch 161, meaning that the support lip 143 has no material in the notch 161. Thus, the surface of the support lip 143 is interrupted in section 16. Section 16 may also be implemented as a thin portion in some embodiments, so that section 16 has a smaller material thickness than the area surrounded by the lip. The width of the notch 161 is preferably greater than the diameter of the hose 3, so that the notch 161 can receive the hose 3. In some embodiments, the portion of the sealing lip 142 disposed between the notch 161 and the hose 3 is also received by the notch 161. The notch 161 deforms the sealing lip 142 such that the sealing lip partially surrounds the hose 3 and seals at the contact points with the hose 3 and the facial skin 4. That is, the sealing lip 142 is guided along the hose 3 and can seal against the user's facial skin 4 next to the hose.

[0063] Furthermore, in some exemplary embodiments, the mask bulge 1 may also have multiple segments 16 that are optionally different in shape and construction. Each lateral region 12 of the lip 14, such as the support lip 143, may have at least one segment 16. Each lateral region 12 of the support lip 143 may also have two or more segments 16, which have different sizes, for example, for different hose diameters. The hose 3 can be guided from the lower left and / or lower right of the mask bulge 1, for example, depending on the location and requirements, through the segments 16 in each of the two lateral regions 12.

[0064] exist Figure 3 The image shows a partially enlarged view of a segment 16 of the face mask protrusion 1, which is an embodiment of a notch 161. Segment 16 extends from an end 162 arranged toward the transition region 21 to a second end 164, which is arranged toward the central opening 15. The notch 161 is further defined by a side edge 165. The notch 161 is characterized in that it contains no material within the boundaries defined by the ends 162, 164, and the side edge 165; that is, the notch is an opening in the support lip 143. Figure 3 In the exemplary embodiment of notch 161 shown, the two ends 162 and 164 are rounded and semi-circular. Side 165 is substantially straight and extends parallel to each other. In other exemplary embodiments, side 165 and / or ends 162, 164 may also have other shapes. Ends 162 and / or 164 may, for example, be flattened or have other geometries and freeform shapes independent of each other. Side 165 may also have a curved orientation independent of each other in some embodiments, for example, extending segmentally into notch 161 or having protrusions. Depending on the length of notch 161, i.e., the extension dimension from end 162 to end 164, side 165 may not be clearly visible, but rather transition into the shape of ends 162 and / or 164. If notch 161 is constructed, for example, as a circular hole, ends 162 and 164 can be considered semi-circular, thus side 165 may not be clearly visible. If not only end 162 but also end 164 is closed, that is, notch 161 is not open toward the central opening 15, then end 164 is also placed on the hose 3, for example.

[0065] The sides 165 are substantially spaced apart by a distance B. This distance B is within the range of the outer diameter of the hose 3, but preferably larger than the outer diameter. In some embodiments, the distance B is also smaller than the diameter of the hose 3. In some embodiments, a plurality of segments 16 or notches 161 are also arranged on the face mask bulge 1, these segments or notches having different distances B between their sides 164, and are thus configured to receive hoses of different diameters. It is also conceivable that, in some embodiments, the distance B decreases, for example, towards the end 162. Thus, for example, the notch 161 can also receive different hose diameters.

[0066] Figure 4 An exemplary mask bulge is shown in a rear view, i.e., from the perspective of observing the transition region 21 of the mask body connector 211. In the exemplary embodiment shown, the support lip 143 has a notch 161 in the lateral region 12, adjacent to the base region 13. An exemplary embodiment is shown in which the lateral regions 12 of the support lip 143 are not connected to each other in the bridge of the nose region 11 and the base region 13. Figure 4The diagram also shows a plane S that extends through the bridge of the nose region 11 and the base region 13. In some embodiments, at least two segments 16 are arranged in the mask bulge 1, the segments being opposite each other about the plane S and having, for example, the same geometry and dimensions (length and width). Two or more segments 16 with different geometries and dimensions may also be arranged, for example, in the lateral regions 12, the segments being arranged symmetrically about the plane S in the opposite lateral regions 12.

[0067] exist Figure 4 The diagram also shows a section AA with a notch 161, which is further shown in... Figure 5 As shown in [the image]. Figure 5 The sealing lip 142 and support lip 143 are seen to run parallel to each other from the transition region 21 or the mask body connector 211 to the central opening 15. In an exemplary embodiment, the sealing lip 142 extends outward so that it can rest against the user's facial skin 4. In an embodiment with two lips 14, the outer lip 14, also known as the lip 14 described below, is furthest from the geometric center of gravity of the mask bulge with the largest surface area. The material thickness of the sealing lip is substantially consistently less than that of the support lip 143. The support lip 143 exemplary has a material thickness that gradually decreases from the transition region 21 toward the central opening 15, thus supporting the mask bulge 1. The smaller material thickness toward the central opening enables, for example, the sealing lip 142 to be supported on the user's face without applying uncomfortable pressure. The material thickness and / or rigidity or strength of the support lip should still be sufficient so that the sealing lip 142 can be guided on the hose 3. In some embodiments, the support lip 143 further serves to ensure that the sealing lip 142 is sealed against the user's facial skin 4 and to support against, for example, unsealing under high breathing pressure. In some embodiments, the mask bulge 1 is made of a single material, wherein different mechanical properties are achieved primarily by varying the geometry and material thickness. In some embodiments, however, portions of the mask bulge 1 may also be made of different materials. For example, a more elastic / stretchable material may be chosen for the sealing lip 142 compared to that for the support lip 143. The support lip 143 may, conversely, be made of a more rigid material. This may, for example, achieve better support and / or shape stability for the support lip 143. The sealing lip 142 may also be more easily guided to seal against the hose 3 by being highly stretchable, wherein the notch 161 of the support lip 143 facilitates that the sealing lip 142 at least partially surrounds the hose 3.

[0068] Figure 6 Showing detailed images Figure 5The portion marked with an X. The outer sealing lip 142 has a smaller material thickness than the inner support lip 143. An example can be seen of a discontinuous or stepped transition from the support lip 143 to the notch 161. In some embodiments, the transition may also be implemented smoothly, meaning the material thickness gradually decreases towards the center of the notch and eventually transitions to a material-free notch.

[0069] Figures 7 to 11 Another exemplary embodiment of the mask protrusion 1 is shown. The mask protrusion 1 here largely corresponds to... Figures 2 to 6 The aforementioned mask protrusion. Unlike the mask protrusion described above, section 16 here is implemented as a thin portion 166. Unlike the notch 161, the thin portion 166 is not an interruption of the support lip 143, but has a significantly smaller material thickness compared to the rest of the support lip 143. In some embodiments, the thin portion 166 is further made of another material, for example, more elastic than the support lip 143.

[0070] In the exemplary embodiment shown, the end 164 of the thin portion 166 extends to the edge 145 of the support lip 143 at the central opening 15, as... Figure 8 As exemplarily shown in the figure. The endpoint 163 of the thin portion 166 can also be seen by the fact that the end 164 of the thin portion is not rounded. Alternatively, it is also conceivable that the end 164 of the thin portion 166 does not extend to the entire edge 145.

[0071] Figure 11 The cross section AA (shown from the cut mask protrusion 1) is shown. Figure 9 )of Figure 10 Detail X. The material thickness of the support lip 143 changes discontinuously in the transition to the thinner portion 166. The discontinuous transition shown here extends in a stepped manner on the inner side of the support lip 143, i.e., on the side away from the user's face. However, the transition may also extend in a stepped manner on the outer side, i.e., on the side facing the user's face. For example, a stepped transition may also be implemented on both sides of the support lip 143.

[0072] In some embodiments, the transition to the thin portion 166 can also be formed by gradually reducing the material thickness. The starting end of the thin portion 166 can be, for example, the starting or ending end of the gradually decreasing portion. A transition region to the thin portion 166 can also be defined. The thin portion 166 is typically implemented with a substantially uniform material thickness; however, in some embodiments, the material thickness can also be varied within the thin portion 166.

[0073] The thin portion 166, compared to the remaining support lips 143, exhibits significantly less rigidity and / or stiffness, either by incorporating a smaller material thickness or by selecting an alternative material, and is more malleable compared to the remaining support lips 143. This reduced rigidity and / or greater malleability allows the support lips 143 to position or guide not only the thin portion 166 but also the sealing lip 142, at least partially around the hose 3. The sealing lip 142 is deformed by lateral regions implemented with greater rigidity and / or thickness on the sides 165 and ends 162 of the support lips 143, such that a portion of the sealing lip 142 is placed on the hose 3 and pressed or pulled against the side of the hose 3 to the user's facial skin 4 and abuts there.

[0074] If multiple segments 16 are arranged on the mask bulge 1, these segments may be partially constructed as notches 161 and also partially constituted by thin portions 166. In some embodiments, additional thin portions 166 in the sealing lip 142 may be arranged, for example, below or parallel to the notch 161 in the support lip 143. In some embodiments, the sealing lip 142 may have a notch 161, and the support lip 143 may have thin portions 166. Furthermore, it is also conceivable, for example, that the sealing lip 142 and the support lip 143 have overlapping thin portions 166 and / or notches 161. It is also conceivable that the overlapping segments have different geometries and / or dimensions. For example, a segment 16 of the sealing lip 142 may be implemented as wider and / or longer than a segment 16 of the support lip 143 (i.e., the distance between ends 162 and 164). It is also conceivable that a segment 16 of the support lip 143 is wider and / or longer than a segment 16 of the sealing lip 142.

[0075] exist Figures 12 to 16 Another exemplary embodiment of the mask protrusion 1 is schematically shown in the figure. Figures 12 to 16 The embodiment shown differs from the aforementioned embodiment in that section 16 is a notch 161 opening toward the central opening 15. That is, the end 164 of the notch 161 extends to the edge 145 of the support lip 143, wherein the endpoints 163 of the notch 161 are not directly connected to each other and at least do not contact each other when no mechanical load (e.g., caused by the mask protrusion 1 being placed on the user's face and the bandage being tightened) is applied to the mask protrusion 1.

[0076] When using the tube 3 between the mask protrusion 1 and the user's facial skin 4, the sealing lip 142 at least partially covers or presses onto the tube 3 through the notch 161. The sealing lip 142 can be deformed by the tube 3 in the section 16, which is here as the notch 161, and thereby at least partially surrounds the tube 3.

[0077] exist Figure 17The front view shows an exemplary embodiment of the mask protrusion 1. The mask protrusion 1 has a lip 14 implemented as a combination of a sealing lip 142 and a supporting lip 143. In the illustrated embodiment, the lip 14 has segments 16 implemented as notches 161 in two lateral regions 12. The two notches 161 are opposed about a plane S passing through the base region 13 and the bridge of the nose region 11. The segments 161 open toward a central opening 15 and thus form an interruption in the surface of the lip 14. When the tube 3 is used with the mask protrusion 1, the notch 161 can receive the tube 3, such that the side 165 of the notch 161 extends along the side of the tube onto the user's facial skin 4. In some embodiments, the endpoints 163 of the notch 161 can be shaped such that the endpoints also extend toward each other without mechanical load (acting on the mask protrusion), but do not contact each other. If the endpoint 163 is shaped such that, for example, it forms a partial circle, the endpoint can rest against the facial skin 4 below the tube 3 and thereby further reduce leakage of the mask bulge 1 if necessary.
