Cushion pad for nasal mask

Abstract

The utility model discloses a nasal mask cushion pad which comprises a pressure reduction pad body, and the pressure reduction pad body comprises a viscous silica gel layer, an anti-sticking layer connected to the upper surface of the silica gel layer and a release layer detachably connected to the lower surface of the silica gel layer. The upper surface of the pressure reduction pad body is provided with an exposing hole which penetrates through the silica gel layer and the anti-sticking layer and is used for exposing the nose of a patient, and under general conditions, the silica gel layer loses original viscous force in the using process because the surface of the silica gel is polluted or adsorbs impurities such as dust, grease and chemical substances, and the nose of the patient can not be exposed. The viscosity of the silica gel often depends on the cleanliness and microstructure of the surface of the silica gel, any external pollutants may destroy the viscosity, and after the silica gel layer is cleaned with water and a cleaning agent, the microstructure of the surface of the silica gel is recovered, and the viscosity of the silica gel is recovered. Therefore, the decompression pad body can be repeatedly used, the treatment cost is reduced, material waste is reduced, meanwhile, when the decompression pad is used, the silica gel layer is pasted on the face of a patient, tight sealing is formed between the silica gel layer and a nasal mask, and therefore gas leakage of a breathing machine is reduced.

Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a nasal mask buffer pad. Background Art

[0002] A nasal mask generally refers to a device used in sleep apnea therapy, mainly for continuous positive airway pressure therapy. The nasal mask generally covers the patient's nose and sometimes also includes the mouth to provide a sealed interface for the constant airflow generated by the ventilator to enter the patient's respiratory tract unobstructed.

[0003] Since the wearing time of the nasal mask is very long during sleep apnea therapy, in order to reduce the pressure of the mask on the face and prevent red marks or pain on the skin after long-term wearing; at the same time, in order to form a tighter seal and reduce gas leakage. Generally, a buffer pad is added between the nasal mask and the patient's face for buffering. In order to prevent the buffer pad from shifting, a glue coating is generally provided on the side of the buffer pad close to the patient's skin. Currently, the buffer pads on the market are generally disposable, and the adhesiveness of the glue coating will drop significantly after use, resulting in the need to replace a new buffer pad when using the nasal mask again after removing the buffer pad, thus increasing the treatment cost and exacerbating the waste of materials.

[0004] The present utility model is made based on the above situation. Summary of the Utility Model

[0005] The utility model overcomes the deficiencies of the prior art and provides a nasal mask buffer pad that can be reused, thereby reducing the treatment cost.

[0006] The present utility model is achieved through the following technical solutions:

[0007] A nasal mask buffer pad includes a decompression pad body. The decompression pad body includes a silicone gel layer with adhesiveness, an anti-adhesive layer connected to the upper surface of the silicone gel layer, and a release layer detachably connected to the lower surface of the silicone gel layer. An exposure hole is provided on the upper surface of the decompression pad body, which penetrates through the silicone gel layer and the anti-adhesive layer and is used to expose the patient's nose.

[0008] For a nasal mask buffer pad as described above, both the anti-adhesive layer and the silicone gel layer are annular, and covering layers extending from the inner and outer sides of the anti-adhesive layer cover the inner and outer side walls of the silicone gel layer.

[0009] For a nasal mask buffer pad as described above, the silicone gel layer includes a straight segment and arc segments symmetrically arranged on both sides of the straight segment. The first ends of the two arc segments are respectively connected to the two ends of the straight segment, and the second ends of the two arc segments are connected to each other.

[0010] A nasal mask cushion as described above, the connection between the arc segment and the straight segment is rounded, and the connection between the two arc segments is rounded. The radius of the rounded corner at the connection between the arc segment and the straight segment is greater than the radius of the rounded corner at the connection between the two arc segments.

[0011] A nasal mask cushion as described above, through holes are also provided at the positions corresponding to the exposed holes on the release layer.

[0012] A nasal mask cushion as described above, the shape of the release layer is the same as that of the silicone gel layer, and an extended eaves is provided on the inner edge and / or outer edge of the release layer to facilitate tearing the release layer by hand.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0014] In this case, the decompression pad body is composed of a silicone gel layer, an anti-sticking layer and a release layer. When in use, the release layer is torn off, and it can be pasted around the patient's nose to buffer the nasal mask. Generally, the silicone gel layer loses its original adhesiveness during use, usually because the surface of the silicone gel is contaminated or adsorbed with impurities such as dust, grease, and chemical substances. The adhesiveness of the silicone gel often depends on the cleanliness and microstructure of its surface, and any foreign contaminants may damage this adhesiveness. When the silicone gel layer is cleaned with water and a cleaning agent, the microstructure of the silicone gel surface is restored, and its adhesiveness also returns. Thus, the decompression pad body can be reused, thereby reducing the treatment cost and reducing the waste of materials. At the same time, when in use, the silicone gel layer is pasted on the patient's face to form a tight seal with the nasal mask, thereby reducing the leakage of the ventilator gas.

[0019] The following further describes the present utility model with reference to the drawings:

[0020] As Figures 1 to 3A nasal mask buffer pad as shown, comprising a decompression pad body 1. The decompression pad body 1 includes a silicone gel layer 11 with adhesiveness, an anti-sticking layer 12 connected to the upper surface of the silicone gel layer 11, and a release layer 13 detachably connected to the lower surface of the silicone gel layer 11. An exposure hole 2 is provided on the upper surface of the decompression pad body 1, which penetrates through the silicone gel layer 11 and the anti-sticking layer 12 and is used to expose the patient's nose. The anti-sticking layer 12 is a waterproof layer or a water-repellent layer, and is not easily damaged when the decompression pad is cleaned.

[0021] The decompression pad body 1 is composed of a silicone gel layer 11, an anti-sticking layer 12, and a release layer 13. When in use, the release layer 13 is torn off, and it can be pasted around the patient's nose to buffer the nasal mask. After use, the impurities such as dust, grease, and chemical substances adsorbed on the surface of the silicone gel layer 11 are washed off with water or a cleaning agent, and its adhesiveness can be restored, so that the decompression pad can be reused, thereby reducing the treatment cost and material waste. At the same time, when in use, the silicone gel layer 11 is pasted on the patient's face, forming a tight seal with the nasal mask, thereby reducing the leakage of the ventilator gas.

[0022] In some embodiments, both the anti-sticking layer 12 and the silicone gel layer 11 are annular. Covering layers 121 extending from the inner and outer sides of the anti-sticking layer 12 cover the inner and outer walls of the silicone gel layer 11, thereby restricting the adhesion of the inner and outer walls of the silicone gel layer 11 to other foreign objects. Among them, the anti-sticking layer 12 and the silicone gel layer 11 are approximately isosceles triangles, so as to better fit the patient's nose.

[0023] Furthermore, the silicone gel layer 11 includes a straight segment 111 and arc segments 112 symmetrically arranged on both sides of the straight segment 111. The first ends of the two arc segments 112 are respectively connected to the two ends of the straight segment 111, and the second ends of the two arc segments 112 are connected to each other. Among them, the connection part of the two arc segments 112 corresponds to the root of the patient's nose, and the connection part of the arc segment 112 and the straight segment 111 corresponds to the patient's cheek. The connection part of the arc segment 112 and the straight segment 111 is rounded, and the connection part of the two arc segments 112 is rounded. The radius of the rounded corner at the connection part of the arc segment 112 and the straight segment 111 is greater than the radius of the rounded corner at the connection part of the two arc segments 112, so that the buffer pad can better fit the patient's facial structure.

[0024] In some embodiments, a through hole 131 is also provided on the release layer 13 corresponding to the exposure hole 2. The shape of the through hole 131 is the same as or similar to the shape of the exposure hole 2, and the size of the through hole 131 is slightly smaller than the size of the exposure hole 2. The shape of the release layer 13 is the same as the shape of the silicone gel layer 11. An extension eaves 132 for easily tearing off the release layer 13 by hand is provided on the inner edge and / or outer edge of the release layer 13.

[0025] In some embodiments, the release layer 13 may be a PE release film, and of course it may also be made of other materials facilitating release.

[0026] In some embodiments, the anti-sticking layer 12 may be a PU film. Of course, it may also be made of other waterproof materials.
