Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a ventilation mask. Background Art

[0002] Ventilation masks can be used for non-invasive ventilation treatments such as chronic respiratory insufficiency, ventilation improvement, and sleep therapy. Existing ventilation masks usually have the following problems: (1) The internal structure of the mask is complex and not easy to clean. For a mask that is reused by a single patient, it brings great inconvenience. For example, if a patient needs to use the ventilation mask for a long time, the mask will be contaminated during use, and it is difficult to quickly clean and put it back on. Patients with serious conditions and high dependence on ventilation masks need to prepare a spare mask, which brings trouble to the patient. (2) The ventilation mask is often made of silicone to fit the part that fits the patient's face, but in fact, the ventilation mask is limited to the initial design. Not all ventilation mask contours can fit the patient's face. Long-term wear can easily compress the patient's face, causing pressure ulcers on the patient's face, causing swelling and pain in the patient's teeth, and other problems. Utility Model Content

[0003] The present application provides a ventilation mask that can solve the problems of the mask being difficult to clean and the mask being easily pressed on the patient's face when worn for a long time.

[0004] To address the above-mentioned technical issues, the present application provides a ventilation mask comprising a mask body, a connector, and a gel. The mask body comprises a recessed cavity, the inner wall of which is provided with a vent extending through the mask body for exhaust. A hydrophobic coating or a hydrophilic coating is provided on the inner surface of the recessed cavity. One end of the connector is connected to an auxiliary breathing circuit, while the other end of the connector is connected to the mask body and communicates with the recessed cavity. The gel is mounted on the mask body and is arranged to surround the patient's mouth and / or nose and contact the patient's facial skin.

[0005] In one embodiment, the gel is removably connected to the mask body.

[0006] In one embodiment, the ventilation mask also includes a first clip, a second clip and a clip, the first clip, the second clip and the clip are arranged on the mask body, and are arranged in sequence in the direction away from the recessed cavity, the mask body is provided with a first clip, the clip is provided with a second clip, and the first clip and the second clip are snap-connected; the gel body includes gel and a fixing part, the fixing part is clamped between the first clip and the second clip, the gel is fixed on the fixing part, and passes through the clip to be arranged on the side of the clip away from the recessed cavity.

[0007] In one embodiment, the first clip, the second clip, the clamping member, and the gel body are all ring-shaped.

[0008] In one embodiment, the ventilation mask further comprises a support sheet, which is disposed between the mask body and the first clip, and the shapes of the support sheet, the fixing member and the gel are consistent.

[0009] In one embodiment, a hydrophobic coating is provided on the inner surface of the recessed cavity, and the hydrophobic coating is configured as a super-hydrophobic nano-silica coating or a polytetrafluoroethylene coating.

[0013] The ventilation mask of the present application is provided with a hydrophobic coating or a hydrophilic coating on the inner surface of the recessed cavity within the mask body. The hydrophobic coating, due to its hydrophobic properties, can reduce the adhesion of liquids generated in the recessed cavity while the patient is wearing the ventilation mask. Even if the mask needs to be replaced immediately, the hydrophobic properties can reduce cleaning time and minimize the need for spare masks. The hydrophilic coating, due to its properties, can reduce the friction coefficient of the material surface, making the interior of the recessed cavity ultra-slippery, allowing liquids to slide easily off the hydrophilic coating, thereby reducing the adhesion of liquids generated in the recessed cavity while the patient is wearing the mask, thereby reducing cleaning time and the need for spare masks. The ventilation mask is also provided with a gel body, which is used to contact the patient's facial skin. Compared with contact with the patient's facial skin, the gel body has greater elasticity and can better conform to the face of different patients. It can conform to the patient's facial curves while distributing pressure on the patient's face, reducing pressure on the patient's face, and alleviating pressure ulcers on the patient's face, tooth swelling and pain, and other problems.

[0022] Please refer to Figure 1-3 The present application provides a ventilation mask, which includes a mask body 10, a connector 20 and a gel body 30.

[0023] The mask body 10 has a recessed cavity 11 therein, and one end of the connector 20 is used to communicate with the auxiliary breathing circuit, and the other end of the connector 20 is connected to the mask body 10 and communicates with the recessed cavity 11. For example, one end of the connector 20 can be communicated with the auxiliary breathing circuit of the ventilator so that the airflow of the auxiliary breathing circuit can flow into the interior of the recessed cavity 11. One side of the recessed cavity 11 has an opening. When the ventilation mask is in use, the opening of the recessed cavity 11 faces the patient's face so that the airflow entering the recessed cavity 11 can flow into the patient's mouth and nose through the opening. A vent 12 is provided on the inner wall of the recessed cavity 11 that passes through the mask body 10. The vent 12 is used for exhaust so that the patient can expel exhaled carbon dioxide gas. When the ventilation mask is in use, the side of the recessed cavity 11 with the opening faces the patient's face and is placed on the patient's face.

[0024] A hydrophobic coating or a hydrophilic coating is provided on the inner surface of the recessed cavity 11. The hydrophobic coating can be configured as a super-hydrophobic nano-silica coating or a polytetrafluoroethylene coating; the hydrophilic coating can be configured as a polyvinyl pyrrolidone coating. The materials of the hydrophobic and hydrophilic coatings are not limited to those mentioned above and may also be other materials.

[0025] The ventilation mask of the present application is coated with a hydrophobic coating or a hydrophilic coating on the inner surface of the recessed cavity 11 in the mask body 10. The hydrophobic coating can reduce the adhesion of liquid generated inside the recessed cavity 11 while the patient wears the ventilation mask due to its hydrophobic properties. Even if the mask needs to be replaced immediately, the hydrophobic property can reduce the cleaning time and minimize the need for spare masks. The hydrophilic coating can reduce the friction coefficient of the material surface according to its properties, so that the inside of the recessed cavity 11 has an ultra-slippery surface, and liquid can easily slide down the hydrophilic coating. Therefore, it can also reduce the adhesion of liquid generated inside the recessed cavity 11 while the patient wears the mask, thereby reducing the cleaning time and reducing the need for spare masks.

[0026] In addition, the existing masks are not effective in maintaining the temperature and humidity during exhalation, and the patient's lips are easily dried out. The ventilation mask of the present application can be coated with a hydrophilic coating inside the concave cavity 11. The hydrophilic coating can retain the temperature and humidity during the patient's exhalation and prevent the patient's lips from drying out.

[0027] The gel 30 is mounted on the mask body 10. The gel 30 can be mounted on the mask body 10 in any manner; it can be fixed or detachably connected to the mask body 10. Examples of connection methods include, but are not limited to, nesting, interference fit, threaded connection, and snap-on connection. The gel 30 is designed to surround the patient's mouth and / or nose, and to contact the patient's facial skin surrounding the mouth and / or nose. The ventilation mask can be used to cover only the patient's nose, only the patient's mouth, or both. Compared to silicone gel, which contacts the patient's facial skin, the gel 32 has greater elasticity and can better conform to the faces of different patients. It can conform to the patient's facial curves while distributing pressure on the patient's face, reducing pressure on the patient's face and alleviating pressure ulcers, tooth swelling, and other issues.

[0028] In one embodiment, the gel body 30 is detachably connected to the mask body 10, and the detachable connection can be, for example, a snap-on connection. The silicone rubber used in existing masks to adhere to the patient's facial skin turns yellow, hardens, and develops an odor over time. It cannot be replaced individually, and replacing the silicone rubber requires replacing the entire mask, which undoubtedly increases maintenance costs for the patient. The ventilation mask of the present application, however, detachably connects the gel body 30 to the mask body 10. After the ventilation mask has been used for a period of time, the gel body 30 can be removed from the mask body 10 and replaced separately, thereby reducing maintenance costs.

[0029] like Figure 2As shown, in one embodiment, the ventilation mask further includes a first clip 40, a second clip 50, and a clip 60. The first clip 40, the second clip 50, and the clip 60 are disposed on the mask body 10, and the first clip 40, the second clip 50, and the clip 60 are all disposed opposite the opening of the recessed cavity 11. The first clip 40, the second clip 50, and the clip 60 are arranged sequentially in a direction away from the recessed cavity 11.

[0030] A first clamping portion 13 is provided on the mask body 10, and a second clamping portion 61 is provided on the clamping piece 60. The first clamping portion 13 and the second clamping portion 61 are snap-connected to fix the first clip 40 and the second clip 50 between the mask body 10 and the clamping piece 60.

[0031] The gel body 30 includes a gel 32 and a fixing member 33. The fixing member 33 is sandwiched between the first clip 40 and the second clip 50. The gel 32 is fixed to the fixing member 33 and passes through the clip 60 to be positioned on the side of the clip 60 away from the recessed cavity 11, thereby covering the clip 60 and contacting the patient's skin. This structure facilitates the removal of the gel body 30 from the mask body 10 when replacement is required. Furthermore, this structure simplifies the installation of the gel 30 and provides a stable mounting structure.

[0032] Furthermore, the first clip 40, the second clip 50, the clamping part 60, and the gel body 30 are all annular in shape, wherein the gel 32 and the fixing part 33 can both be annular. By setting each installed part to be annular, the user can breathe the gas in the recessed cavity 11 through the hole in the middle of the annular structure.

[0033] In one embodiment, the ventilation mask further includes a support sheet 90 , which is disposed between the mask body 10 and the first clip 40 , and the support sheet 90 is consistent in shape with the gel 32 , so that the support sheet 90 can support the entire gel 32 .

[0034] In one embodiment, if Figure 1-3 As shown, the ventilation mask also includes a headband fixing frame 70, which is installed on the mask body 10. The headband fixing frame 70 is used to install a fixing belt. By tightening the fixing belt around the patient's head, the ventilation mask can be tightly fastened to the patient's face.

[0035] In one embodiment, if Figure 2 As shown, the ventilation mask also includes a sealing plug 80. An oxygen hole 14 that penetrates the mask body 10 is also provided on the inner wall of the recessed cavity 11. The sealing plug 80 can seal the oxygen hole 14. The oxygen hole 14 can be connected to an oxygen supply device when oxygen needs to be supplied to the patient. When oxygen does not need to be supplied to the patient, the sealing plug 80 can be used to block the oxygen hole 14.

[0036] The above examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, modifications or substitutions can be made based on the ideas of the present invention.
