Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a lightweight, comfortable, and non-invasive face mask. Background Technology

[0002] In clinical medicine and home care, oxygen masks are widely used in oxygen therapy, nebulization therapy, and respiratory assistance. Traditional oxygen masks typically use headbands or straps to secure the mask to the patient's face. The tension of the straps ensures a tight seal between the mask edges and the patient's facial skin, thus sealing the oxygen supply space.

[0003] However, headbands or straps need to be wrapped around the back of the patient's head or ears for fixation, which is a rather cumbersome process. When worn for a long time, the straps exert continuous pressure on the patient's head and ears, which can easily cause discomfort. In addition, the edges of existing oxygen masks are relatively hard, and when fixed by headbands or straps, they put a lot of pressure on the face. Wearing them for a long time can easily cause local pressure sores or skin damage, especially for infants, the elderly, or patients with facial trauma.

[0004] Meanwhile, due to differences in patients' facial contours and wearing angles, the headband fixation method makes it difficult to achieve a uniform fit between the mask and the face, which can easily lead to local air leakage, affecting oxygen concentration and treatment effectiveness. To ensure a seal, medical staff often need to further tighten the straps, but this can exacerbate the discomfort caused by pressure on the patient's face.

[0005] Therefore, it is necessary to make further improvements to the existing technology. Summary of the Invention

[0006] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide a lightweight, comfortable, and non-invasive face mask.

[0007] To achieve the above objectives, a lightweight, comfortable, and non-invasive face mask according to an embodiment of the present invention includes a fitting component, a face mask component, and a connector.

[0008] The bonding component includes an adhesive patch and a first connecting frame. The adhesive patch is adapted to be pasted on the patient's face and is arranged around the patient's mouth and nose. The first connecting frame is disposed on the surface of the adhesive patch. The mask assembly includes a second connecting frame and a mask body, the mask body being fitted onto the second connecting frame, and the second connecting frame being detachably fastened to the first connecting frame.

[0009] The connector is located on the mask body and is used to connect to an external oxygen pipeline.

[0010] In addition, a lightweight, comfortable, and non-invasive face mask according to the above embodiments of the present invention may also have the following additional technical features: According to one embodiment of the present invention, the adhesive sheet includes a main body and an easy-tear portion.

[0011] The main body has an adhesive surface on one side for attaching the main body to the patient's face, and a through hole in the middle of the main body for accommodating the patient's mouth and nose.

[0012] The tear-off portion is located inside the through hole, and its edge forms a tear-off structure with the main body, so that the tear-off portion can be torn off the main body during use.

[0013] According to one embodiment of the present invention, a first airbag is provided between the first connecting frame and the adhesive sheet, and the first airbag extends circumferentially along the first connecting frame.

[0014] According to one embodiment of the present invention, a second airbag is connected between the second connecting frame and the mask body, and the second airbag extends circumferentially along the second connecting frame.

[0015] According to one embodiment of the present invention, the surface of the first connecting frame is provided with a protrusion, the protrusion extending circumferentially along the first connecting frame, and a slot is provided on the outer side of the protrusion perpendicular to the adhesive piece, the slot extending circumferentially along the protrusion.

[0016] The second connecting frame is sleeved on the outside of the protrusion, and the inner side of the second connecting frame is provided with a plurality of retaining parts along its circumference. When the second connecting frame is sleeved on the outside of the protrusion, the plurality of retaining parts are all retained in the slot.

[0017] During the process of the second connecting frame being fitted onto the protrusion, the retaining part abuts against the surface of the protrusion and undergoes elastic deformation under the pushing action of the protrusion to pass over the protrusion. When the retaining part moves to the position opposite to the slot, the retaining part elastically resets and is engaged in the slot.

[0018] According to one embodiment of the present invention, the end of the holding part is provided with arc-shaped guide surfaces on both sides for guiding it to slide into or out of the card slot.

[0019] According to one embodiment of the present invention, a sealing strip is provided on the second connecting frame. The sealing strip extends circumferentially along the second connecting frame. When the second connecting frame is connected to the first connecting frame, the sealing strip is axially pressed between the second connecting frame and the first connecting frame to seal the mating gap between them.

[0020] According to one embodiment of the present invention, the mask body is made of a transparent flexible material.

[0021] According to one embodiment of the present invention, the side of the adhesive patch away from the second connecting frame is covered with a protective film.

[0022] According to one embodiment of the present invention, the edge of the protective film is provided with an extension to facilitate the removal of the protective film from the adhesive sheet.

[0023] According to an embodiment of the present invention, a lightweight, comfortable, and non-invasive face mask is provided. By using an adhesive patch, the mask is directly attached to the patient's face, replacing the traditional headband or strap-like fixation method. This eliminates continuous pressure on the patient's head and ears from the straps, avoiding pressure sores or skin damage caused by overly tight straps. It is particularly suitable for infants, the elderly, and patients with facial trauma. Furthermore, the first and second connecting frames are detachably fastened, allowing the mask body to be easily removed from the adhesive patch so that the patient can expose their mouth and nose when needed. The invention has a simple overall structure, good comfort, and effectively avoids trauma caused by pressure.

[0024] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] The present invention provides a lightweight, comfortable, and non-invasive face mask according to an embodiment of the present invention, with reference to the accompanying drawings.

[0035] Reference Figures 1 to 10 As shown, a lightweight, comfortable, and non-invasive face mask according to an embodiment of the present invention includes a fitting component 10, a face mask component 20, and a connector 23.

[0036] The bonding component 10 includes an adhesive sheet 11 and a first connecting frame 12. The adhesive sheet 11 is adapted to be pasted on the patient's face and is arranged around the patient's mouth and nose. That is, the adhesive sheet 11 is roughly in the shape of a ring, and its inner space is used to accommodate the patient's mouth and nose. The first connecting frame 12 is disposed on the surface of the adhesive sheet 11. The first connecting frame 12 is preferably a ring-shaped frame made of a material that can be deformed under pressure. Its shape is adapted to the outer contour of the adhesive sheet 11 and is roughly in the shape of an irregular ring of the contour of the mouth and nose of the human face.

[0037] The mask assembly 20 includes a second connecting frame 21 and a mask body 22. The mask body 22 is fitted over the second connecting frame 21, meaning the edge of the mask body 22 is connected and fixed to the second connecting frame 21. The second connecting frame 21 is detachably fastened to the first connecting frame 12. When the second connecting frame 21 and the first connecting frame 12 are engaged, a relatively sealed oxygen supply space is formed between the mask body 22 and the patient's face.

[0038] The connector 23 is located on the mask body 22 and is used to connect to an external oxygen pipeline. The connector 23 can be a standard oxygen supply pipeline interface, such as a tapered connector or a threaded connector, to facilitate quick connection and disconnection with the oxygen pipeline.

[0039] Based on the above, by setting the adhesive patch 11, the mask is directly attached to the patient's face, replacing the traditional headband or strap-on fixing method. This eliminates the continuous pressure of the strap on the patient's head and ears, and avoids pressure sores or skin damage caused by overly tight straps. It is especially suitable for infants, the elderly, and patients with facial trauma. Furthermore, the first connecting frame 12 and the second connecting frame 21 are connected by a detachable fastener, allowing the mask body 22 to be easily removed from the adhesive patch 11 so that the patient can expose their mouth and nose when needed. The overall structure of this invention is simple, comfortable to use, and effectively avoids trauma to the patient caused by pressure.

[0040] Preferably, in one embodiment of the present invention, the adhesive sheet 11 includes a main body portion 111 and an easy-tear portion 112.

[0041] The main body 111 has an adhesive surface on one side for attaching it to the patient's face. The adhesive surface is coated with medical pressure-sensitive adhesive to ensure sufficient adhesion between the adhesive patch 11 and the patient's facial skin, while also facilitating removal from the patient's face after treatment and minimizing skin damage. The main body 111 has a through-hole 1111 in the middle to accommodate the patient's mouth and nose. That is, the position of the through-hole 1111 corresponds to the patient's mouth and nose area to ensure unobstructed breathing when wearing the mask.

[0042] The tearable part 112 is disposed within the through hole 1111, and its edge forms a tearable structure with the main body 111, so that the tearable part 112 can be easily torn off the main body 111 during use. Specifically, the connection between the tearable part 112 and the main body 111 can be formed into a tearable structure by means of dotted lines (i.e., continuously arranged pinholes or cuts along the connection), slits (i.e., linear cuts along the connection), or thinning treatment (i.e., reducing the material thickness at the connection), so that the tearable part 112 and the main body 111 remain connected under normal conditions, but can be neatly separated along the tearable structure when subjected to external force. During use, the tearable part 112 is torn off along the tearable structure to adapt to the patient's facial features.

[0043] Advantageously, in one embodiment of the invention, a first airbag 13 is provided between the first connecting frame 12 and the adhesive piece 11, the first airbag 13 extending circumferentially along the first connecting frame 12.

[0044] Thus, by placing a first airbag 13 between the adhesive patch 11 and the first connecting frame 12, the compressibility and elastic deformation of the gas inside the airbag form a soft air cushion buffer layer between the first connecting frame 12 and the patient's face. This effectively absorbs and disperses the pressure of the first connecting frame 12 on the patient's face, preventing the rigid connecting frame from directly pressing on the patient's facial skin. Even after prolonged wear, it is less likely to cause pressure marks or pain. The first airbag 13 extends circumferentially along the first connecting frame 12, forming a continuous annular air cushion around the mouth and nose. The gas inside the airbag can undergo corresponding local deformation according to the contour differences of different areas of the patient's face. The airbag is compressed more in protruding areas and expands to fill in concave areas, thereby achieving an adaptive fit to the patient's facial contours.

[0045] Specifically, the first airbag 13 is disposed between the surface of the first connecting frame 12 facing the adhesive piece 11 and the adhesive piece 11, that is, the first airbag 13 is sandwiched between the first connecting frame 12 and the adhesive piece 11. The first airbag 13 extends circumferentially along the first connecting frame 12, that is, the first airbag 13 has a ring-shaped or approximately ring-shaped hollow bladder structure, and its extension trajectory is adapted to the contour of the first connecting frame 12. The internal filling medium of the first airbag 13 is preferably air, but it can also be filled with inert gas or other gaseous media with good compressibility, utilizing the good compressibility and flowability of the gas to achieve cushioning and self-adaptive fitting functions. The first airbag 13 can be connected and fixed to the adhesive piece 11 and / or the first connecting frame 12 by adhesive bonding. For example, the upper surface of the first airbag 13 is bonded and fixed to the lower surface of the first connecting frame 12, and the lower surface of the first airbag 13 is bonded and fixed to the upper surface of the adhesive piece 11.

[0046] Preferably, in one embodiment of the present invention, a second airbag 24 is connected between the second connecting frame 21 and the mask body 22, and the second airbag 24 extends circumferentially along the second connecting frame 21.

[0047] Thus, by setting a second airbag 24 between the second connecting frame 21 and the mask body 22, when the mask body 22 is subjected to external force collision or compression, the second airbag 24 absorbs and buffers the impact energy through its own compression deformation, effectively slowing down the transmission of external force from the mask body 22 to the second connecting frame 21 and the patient's face, reducing the risk of impact injury to the patient's face from external force, and significantly improving the safety of use.

[0048] Specifically, the second airbag 24 is disposed between the second connecting frame 21 and the mask body 22, that is, the upper end (or outer side) of the second airbag 24 is connected to the edge of the mask body 22, and the lower end (or inner side) of the second airbag 24 is connected to the second connecting frame 21. The second airbag 24 extends circumferentially along the second connecting frame 21, that is, the second airbag 24 has a ring-shaped or approximately ring-shaped hollow bladder structure, and its extension trajectory matches the contour of the second connecting frame 21. When the mask body 22 is placed on the second connecting frame 21, the second airbag 24 is located at the connection interface between the two.

[0049] Advantageously, the internal filling medium of the second airbag 24 is preferably air, but other inert gases may also be used. The material of the second airbag 24 is preferably a flexible film material, such as medical-grade polyvinyl chloride, thermoplastic polyurethane, or silicone film, to ensure that the second airbag 24 has good flexibility and elastic deformation capability.

[0050] Preferably, in one embodiment of the present invention, the surface of the first connecting frame 12 is provided with a protrusion 121, the protrusion 121 extends circumferentially along the first connecting frame 12, and a slot 122 is provided on the outer side of the protrusion 121 perpendicular to the adhesive piece 11, the slot 122 extends circumferentially along the protrusion 121.

[0051] The second connecting frame 21 is sleeved on the outside of the protrusion 121. Multiple retaining portions 211 are provided circumferentially on the inner side of the second connecting frame 21. When the second connecting frame 21 is sleeved on the outside of the protrusion 121, all of the retaining portions 211 are engaged within the retaining groove 122. Preferably, the retaining portions 211 and the second connecting frame 21 are integrally injection molded, utilizing the elastic deformation capability of the plastic material itself to achieve the engaging function.

[0052] During the process of the second connecting frame 21 being fitted onto the protrusion 121, the retaining part 211 abuts against the surface of the protrusion 121 and undergoes elastic deformation under the pushing action of the protrusion 121 to pass over the protrusion 121. When the retaining part 211 moves to be opposite to the slot 122, the retaining part 211 elastically resets and is locked into the slot 122.

[0053] Thus, through the snap-fit ​​between the retaining part 211 and the slot 122, assembly can be completed simply by pressing the second connecting frame 21 axially without the need for any external tools. Disassembly can be completed by holding down the adhesive piece 11 and pulling the second connecting frame 21 outward. This enables rapid assembly and disassembly of the mask body 22, significantly improving clinical operational efficiency, and is especially suitable for emergency situations requiring rapid response. Multiple retaining parts 211 are distributed circumferentially along the second connecting frame 21 and are all engaged within the same annular slot 122, forming a multi-point uniform limiting. After the retaining part 211 is engaged in the slot 122, the slot 122 provides axial limiting for the retaining part 211. Without deliberate pulling by external force, the second connecting frame 21 will not detach from the first connecting frame 12 due to accidental traction or changes in patient position, ensuring a safe and reliable connection.

[0054] Preferably, in one embodiment of the present invention, the end of the retaining part 211 is provided with arc-shaped guide surfaces 2111 on both sides for guiding it to slide into or out of the card slot 122. Specifically, one end of the retaining part 211 is connected to the inner wall of the second connecting frame 21 (i.e., the root of the retaining part 211), and the other end is a free end that protrudes toward the center of the second connecting frame 21. The arc-shaped guide surfaces 2111 are provided on both sides of the free end of the retaining part 211 along the circumferential direction of the inner wall of the second connecting frame 21, that is, the arc-shaped guide surfaces 2111 are located on both circumferential sides of the free end of the retaining part 211.

[0055] Thus, by providing arc-shaped guide surfaces 2111 on both sides of the end of the retaining part 211, during assembly, the arc-shaped guide surfaces 2111 first contact the surface of the protrusion 121, transforming the original sharp, rigid contact into a smooth, arc-shaped sliding fit. This effectively reduces the frictional resistance when the retaining part 211 passes over the protrusion 121, allowing the operator to complete the assembly with only a small amount of pressure, making the operation easier and more convenient. The arc-shaped guide surfaces 2111 also make the stress distribution of the retaining part 211 more uniform during deformation under stress, avoiding localized stress concentration caused by sharp corners, effectively preventing cracks or breakage of the retaining part 211 due to repeated stress, and extending the assembly and disassembly life of the connection structure.

[0056] Preferably, in one embodiment of the present invention, the second connecting frame 21 is provided with a sealing strip 212, the sealing strip 212 extends circumferentially along the second connecting frame 21, and when the second connecting frame 21 is connected to the first connecting frame 12, the sealing strip 212 is axially pressed between the second connecting frame 21 and the first connecting frame 12 to seal the mating gap between the two.

[0057] Thus, when the second connecting frame 21 and the first connecting frame 12 are engaged, the sealing strip 212 is axially pressed between them. Through its own elastic deformation, it fills and seals the gap between them, forming a continuously extending circumferential sealing strip. This effectively prevents oxygen gas from leaking outwards from the connection point, ensuring the airtightness of the oxygen supply space and the effectiveness of oxygen therapy. The sealing strip 212 is elastic and, when compressed, can deform according to the actual gap between the first connecting frame 12 and the second connecting frame 21—more deformation for larger gaps and less deformation for smaller gaps—thereby automatically compensating for the fit tolerances between the two connecting frames. This reduces the requirements for machining precision and simplifies the manufacturing process.

[0058] Advantageously, the sealing strip 212 can be integrally molded with the second connecting frame 21 through a two-stage injection molding process (i.e., two-color injection molding), so that the sealing strip 212 and the second connecting frame 21 are integrated into one unit, eliminating the need for separate assembly and ensuring a firm connection that will not fall off or shift during repeated disassembly and assembly. The sealing strip 212 can also be fixed to the end face of the second connecting frame 21 by means of adhesive bonding or embedding.

[0059] Specifically, the cross-sectional shape of the sealing strip 212 is not limited and can be circular, O-shaped, D-shaped, lip-shaped, or rectangular, etc. In a preferred embodiment, the cross-section of the sealing strip 212 is D-shaped or lip-shaped, with its flat side facing the second connecting frame 21 and its arc-shaped surface or lip facing the first connecting frame 12. Under pressure, the arc-shaped surface or lip can better fit with the surface of the first connecting frame 12, enhancing the sealing effect. Furthermore, the height of the sealing strip 212 (i.e., the axial protrusion) is preferably 0.5mm to 2mm, so as to ensure sufficient compression while avoiding the second connecting frame 21 from failing to snap into place due to excessive protrusion.

[0060] Preferably, in one embodiment of the present invention, the mask body 22 is made of a transparent flexible material.

[0061] Thus, the mask body 22 is made of transparent material, allowing medical staff to directly observe the real-time condition of the patient's mouth and nose without removing the mask during treatment. This includes lip color, mucosal condition, presence or absence of secretions or vomit, respiratory rate and amplitude, etc., which helps to detect changes in the condition in a timely manner and take corresponding measures, ensuring the safety and monitorability of the treatment process.

[0062] Specifically, the mask body 22 is made of a medical-grade polymer material with good light transmittance and flexibility. The light transmittance of the mask body 22 is preferably above 85% to ensure that medical personnel can clearly observe the patient's mouth and nose area through the mask body 22. The material hardness of the mask body 22 is preferably Shore A hardness of 30A to 80A, ensuring sufficient flexibility to adapt to facial contours while also possessing a certain structural strength to prevent the mask body 22 from excessively collapsing and adhering to the patient's mouth and nose area during wear, thus affecting breathing.

[0063] Preferably, in one embodiment of the present invention, the side of the adhesive patch 11 away from the second connecting frame 21 is covered with a protective film 25.

[0064] Thus, the protective film 25 covers the adhesive surface of the adhesive patch 11, effectively isolating the adhesive surface from the external environment when the mask is not in use, preventing dust, impurities or foreign objects from adhering to the adhesive surface, avoiding loss of adhesiveness or reduction of adhesiveness due to contamination before use, and ensuring that the adhesive patch 11 can form a firm and reliable bond with the patient's facial skin when used.

[0065] Specifically, the main body 111 of the adhesive patch 11 has two opposing sides, one side being the adhesive surface for adhesion to the patient's facial skin; the other side is the non-adhesive surface for connection to the first connecting frame 12. A protective film 25 covers the side of the adhesive patch 11 away from the second connecting frame 21, i.e., it covers the adhesive surface of the adhesive patch 11, isolating the adhesive surface from the external environment. The size of the protective film 25 is adapted to the adhesive surface; that is, the shape and size of the protective film 25 match the shape and size of the adhesive surface to ensure that the entire area of ​​the adhesive surface is covered by the protective film 25, avoiding localized exposure. The protective film 25 is a release film, with a release agent (such as silicone oil or fluorinated release agent) coated on the side facing the adhesive surface. This provides a moderate release force between the protective film 25 and the adhesive surface, ensuring that it adheres firmly to the adhesive surface during storage and transportation without detaching on its own, and can be easily removed with appropriate force when needed, leaving no adhesive residue or release agent on the adhesive surface after removal, thus not affecting the bonding performance of the adhesive surface.

[0066] Preferably, in one embodiment of the present invention, the edge of the protective film 25 is provided with an extension 251 to facilitate the removal of the protective film 25 from the adhesive sheet 11.

[0067] Thus, by providing an extension 251 at the edge of the protective film 25, the user can easily pinch the extension 251 to tear it off without having to pry it off with their fingernail. Especially when the adhesive surface is strong or the protective film 25 is tightly attached to the adhesive surface, the extension 251 provides a clear point of force application, effectively reducing the difficulty of tearing off and improving the efficiency of preparation before wearing the mask.

[0068] Specifically, the extension 251 is disposed at the edge of the protective film 25, extending outward from the edge of the protective film 25 and integrally formed with the protective film 25. The extension 251 protrudes beyond the edge of the adhesive sheet 11, that is, the extension 251 does not contact the adhesive sheet 11 or only partially contacts it when the protective film 25 covers the adhesive sheet 11. Therefore, the extension 251 is not sticky, making it easy for the user to pinch and operate.
