Face protection device and its supporting frame

Technical field

The present invention relates to the technical field of medical equipment, and in particular to a face protection device and a support frame for preventing bacteria or viruses from contacting medical staff through droplets.

Background technique

At present, when medical staff are dealing with patients with extremely infectious diseases, in order to prevent the medical staff from being infected during the nursing process, the medical staff usually need to wear protective clothing and equipment to prevent infection during the treatment. For example, when dealing with respiratory infectious diseases, viruses or bacteria may be spread through droplets. Medical staff need to wear protective clothing, goggles and masks, and in severe cases, they may also install protective masks.

technical problem

The existing protective mask equipment is generally composed of protective film and head fixing hoop. On the one hand, the existing protective film design does not adequately cover the human face. On the other hand, the protective film, the head fixing hoop and the forehead are left between the face There are gaps, so the overall protection effect is not ideal. In addition, after the existing protective mask is worn, the distance between the protective film and the face is small, which affects the wearing of N95 masks and other protective equipment such as goggles.

In order to solve the above problems, the first object of the present invention is to provide a face protection device that is convenient to wear and has good protection.

Embodiments of the present invention

The first embodiment of the face protection device:

1 and 2, the face protection device 1 includes a cord 12, a transparent cover 13, a support frame 11, and an elastic seal (not shown). The elastic seal is located on the inner side wall 117 of the support frame 11, and the transparent cover 13 One end is connected to the outer side wall 118 of the support frame 11, and the second end of the transparent cover 13 extends away from the support frame 11. The support frame 11 has a forehead support section 115 and two side forehead support sections 114. The first end of each side forehead support section 114 is smoothly connected to one end of the forehead support section 115 through a circular arc section. The two side forehead support sections 114 The forehead support section 115 is arranged symmetrically. The inner side wall 117 of the forehead support section 115 can be pressed against the forehead of the face 2 through elastic seals, and the inner side walls 117 of the two side forehead support sections 114 can be pressed against both sides of the forehead of the face through elastic seals. . The elastic sealing element can be a rubber elastic gasket or a sponge gasket, etc., with a thickness between 1 mm and 3 mm. The support frame 11 is in contact with the face of the human face 2 through the elastic seal, which can reduce the discomfort caused by the pressure on the face, and at the same time prevent the existence of gaps that may cause bacteria or viruses to enter the face.

The second end of each forehead support section 114 has a fixing portion 112, and the cord 12 is detachably bound to the fixing portion 112. In this embodiment, a connecting plate 116 extends from the second end of each side forehead support section 114. The connecting plate 116 is provided with two through holes 113, and the cantilever between the two through holes 113 forms a fixing portion 112. The rope belt 12 can be a rope, a rubber band, an elastic band, etc. The rope belt 12 passes through the two through holes 113 and is detachably bound to the cantilever, that is, on the fixed portion 112, so that the support frame 11 can be tightened by the rope belt 12 It is fixed on the head.

Among them, the main functions of the support frame 11 are: 1. It can be worn on the head; 2. It is used to support the transparent cover 13; 3. The transparent cover 13 covers the curved surface of the face. Therefore, the support frame 11 can be made of three-dimensional printed metal or plastic. , Ceramics, cloth and other composite materials, or produced by injection molding machines through molds, or produced by die-casting or casting methods. The support frame 11 can be made of plastic-like materials, multiple different plastic materials (including soft and hard plastic materials), metal, ceramics, composite materials, and so on. However, in consideration of reducing the load, reducing the discomfort of long-term wearing, etc., the support frame 11 should be made of materials with a lighter specific gravity.

The material used for the transparent cover 13 is a transparent sheet or film that does not block the line of sight, which will be contaminated with viruses or bacteria during use. Therefore, the transparent cover 13 is a disposable material and is disposable. The transparent cover 13 is attached to the outer side wall 118 of the support frame 11 in an arc as a whole. The length of the transparent cover 13 arranged along the outer side wall 118 of the support frame 11 in this embodiment is between 250 mm and 400 mm. 13 The longitudinal height from the first end to the second end is between 100 mm and 400 mm, so that the protective area of the transparent cover 13 is large, and the enlarged longitudinal height extends from the forehead of the face 2 to below the chin, and even to the shoulder position . At the same time, an appropriate arc arrangement is used to cover the face of the wearer's face 2 in the horizontal direction, and both sides extend to the ears, and even extend to the position behind the ears close to the back of the head, so as to achieve a larger range of face coverage and further improve the protective effect. In addition, at least one side of the transparent cover 13 is provided with a coating to increase the corresponding functions, such as an anti-fog coating to prevent the vapor generated by the breathing of medical staff from condensing and blocking the line of sight, and a color-changing coating to remind medical staff to replace new films, etc. Wait.
