Description

Disposable curing molded oxygen mask

technical field

It relates to the technical field of medical devices, and specifically relates to a disposable cured and molded oxygen mask.

Background technique

Generally, airtight oxygen supply or airtight assisted breathing, before breathing is controlled, the mask needs to be close to the face to achieve airtightness. Only when airtightness is achieved, the positive pressure of gas provided by the outside will press the required gas into the airway through pressure conduction. However, each patient's face is different and requires different types of masks to meet the requirements. Ordinary ordinary masks are difficult to achieve complete airtightness, resulting in a small or severe air leak, resulting in poor ventilation or even hypoxia for the patient. This requires a special mask to complete. And there are many types of special hemp masks, less use, high price, less storage and so on. Traditional adjustable face masks often need to be used multiple times because they are usually inflated, which is neither environmentally friendly nor hygienic. It is also expensive and difficult to meet actual use needs. In view of this, to overcome the above defects in the prior art and to provide a new disposable oxygen mask that can fit the facial contours of different patients has become a technical problem to be solved urgently in this field.

Contents of the invention

The purpose of the present invention is to solve the shortcoming in the prior art, and propose a kind of one-time cured molding oxygen mask

In order to achieve the above object, the present invention adopts the following technical solutions: a disposable solidified oxygen mask, which is characterized in that it includes a mask body, an oxygen delivery hole, a gas delivery tube, a sealing part, a fixed side strip, and the middle part of the mask body The oxygen delivery hole is provided, and the gas delivery tube is connected to the mask main body through the oxygen delivery hole; the side edge of the middle part of the mask main body is also provided with the fixed side strips for fixing the face. The sealing part is sequentially arranged along the side edge of the mask main body. The sealing part is composed of an upper layer of the cavity and a lower layer of the cavity. The upper layer of the cavity is arranged in parallel with the lower layer of the cavity to form a cavity interlayer. The cavity The lower layer is provided with a light guiding structure, the light guiding structure includes a light guiding layer made of light guiding material, and a light guiding body, the inner wall of the light guiding body totally reflects the light transmitted inside.

Further, the fixed side strip is an elastic adjustable structure.

Beneficial technical effects of the present invention: by adding a wrapping layer filled with light-cured resin on the edge of the breathing mask, the sealing layer of the breathing mask can be molded and fixed during use, so that the whole mask can fit the contour of the patient's face more, and can Better play a sealing role and make the breathing mask work better. Compared with the traditional inflatable and fitted breathing mask, the invention is disposable, more environmentally friendly, less prone to cross-infection, and at the same time greatly reduces the time for users to adapt, so that users can quickly obtain the proprietary equipment they need.

Detailed ways

In order to further elaborate the technical means and effects that the present invention adopts for reaching the intended invention purpose, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the present invention are described in detail as follows:

A disposable cured and molded oxygen mask, characterized in that it comprises a mask body (1), an oxygen delivery hole (2), a gas delivery tube (3), a sealing part (4), a fixed side strip (7), the mask The middle part of the main body (1) is provided with the oxygen delivery hole (2), and the gas delivery pipe (3) is connected with the mask main body (1) through the oxygen delivery hole (2); the mask main body (1 ) is provided with the fixed side strips (7) on the side of the middle edge for face fixing, and the sealing part (4) is sequentially arranged along the side edge of the mask body, and the sealing part (4) is formed by the upper layer of the cavity (5) and the cavity lower layer (8), the cavity upper layer (5) is arranged in parallel with the cavity lower layer (8) to form a cavity interlayer (9), and the cavity lower layer (8) is provided with A light guiding structure (6), the light guiding structure (6) comprising a light guiding layer made of light guiding material, and a light guiding body, the inner wall of the light guiding body totally reflects the light transmitted inside it.

Further, the fixed side strip (7) is an adjustable elastic structure.

When in use, firstly wear the mask according to the contour of the patient's face, and secondly, use the injection device to inject fluid light-cured material into the cavity interlayer; after the cavity interlayer is filled, the light-cure material will The light-curable material flows out through the hole and is filled between the outer layer of the cavity and the face; after the light-curable material is filled, the light corresponding to the light-curable material is used to irradiate the filled light-curable material through the light guide structure, so that the filled light-curable material The material cures, resulting in a sealing part that conforms to the shape of the face. Ensure the tightness of the mask. After completing the above steps, fix the two side fixing strips on both sides of the face, adjust the tightness of the fixing side strips, and start using.

In this embodiment, the inner wall of the light guide body has the function of total reflection of light, and when the light is transmitted inside, the total reflection phenomenon occurs after the light comes into contact with the inner wall. The light guide can be an optical fiber or other materials with light guide function. Its role is to connect with the external ultraviolet emitting device, so that the photo-curable material in the cavity interlayer can receive ultraviolet light irradiation. When irradiated with ultraviolet light, it can introduce ultraviolet light through any section of the outer side.

Specifically, both the upper layer of the cavity and the lower layer of the cavity are made of flexible medical plastics, which can deform and conform to the curve of the patient's face within a certain range.

The above-mentioned embodiment is only a preferred embodiment of the present invention, and cannot be used to limit the protection scope of the present invention. Any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of the present invention. Scope of protection claimed.
