Description

Breathing protective head cover

Technical Field

The invention relates to a breathing protection device, in particular to a medical breathing protection device.

Background

The existing medical respiratory protection device is mainly a mask. However, masks have significant drawbacks in several respects:

first, it cannot protect the organs except mouth and nose. Recently, new types of coronavirus pneumonia have been heavily recognized that airborne infectious diseases are likely to be transmitted not only through the mouth and nose, but also through the eyes and other facial organs; therefore, new respiratory protection requirements have not been met by relying solely on masks. Even if the mask is combined with a protective mask or protective eyepieces for use, the problem also exists; the most important problem is that, since such a combination does not form an integral protection system, there are significant leaks of protection at the junction, for example, there are significant gaps between the medical mask and the face shield, which, although having a protective effect against splashed droplets, are still largely exposed to the risk of infection, given that the air is mobile; although the sealing degree of the protective eyepiece is better, the protective eyepiece and the mask have an overlapping part, and the complete sealing at the junction of the overlapping part is difficult to achieve.

Secondly, the use of air filtering materials is not scientific. A person breathes through the mouth, nose, and more precisely, most notably the nose. However, the existing masks cover the entire lower half of the face with expensive air filter material, which is very unscientific because the cheeks are not breathing.

And thirdly, the service life is ultra-low. In order to ensure the safety of respiratory protection, the mask is disposable and can not be used repeatedly at least; this is because bacteria and viruses are likely to be adsorbed in the air filter material of the mask during use of the mask; cleaning and disinfecting the mask can destroy the performance of the air filtration material. However, this practice of discarding the mask used once or several times is wasteful, and is particularly surprising given the large base of mask use in large public health events (such as the current new coronavirus pneumonia epidemics).

Disclosure of Invention

In order to overcome the defects of insufficient protection of the existing mask, unscientific use of air filtering materials, ultra-low service life and the like, the invention provides a medical respiratory protection device.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a respiratory protection hood comprises a hood body and an air filtering module; the head cover main body is a protective device which is made of air-tight soft material and covers the whole head, the air filter module (a module box which is made of air filter material and just covers the nose area can be connected or separated with the head cover main body at the breathing hole through a connecting mechanism, and the head cover main body can be cleaned and sterilized after the air filter module is detached, so that the head cover main body can be repeatedly used.

The shape, size and connector mode of the air filtering module are standardized so as to meet the requirements of batch production and applicability; the thickness and the structure of the filtering material in the air filtering module are set to different specifications so as to meet different requirements of different medical occasions on protection grades;

the breathing port is arranged at the front side of the hood main body and the nose of a wearer, and can be connected or separated with the air filtering module through a connecting mechanism and also connected or separated with the portable oxygen bottle pipeline through the connecting mechanism.

The main body of the hood can be made in a shape conforming to the shape of the head, and the diameter of the neck is smaller than that of the section of the head; a lower end wearing opening is arranged below the hood main body, and a vertical wearing opening is arranged at the rear part; the upper end of the vertical wearing opening is fixed, and the lower end of the vertical wearing opening can be opened, so that the head cover can be opened in an inverted V shape; the vertical wearing opening is closed through a sticking zipper, the sticking zipper has a certain width, and a wearer can adjust the integral tightness degree of the hood; a neckline tightening belt surrounding the neck is arranged along the edge of the lower wearing opening, so that the main body of the head cover is further closed, and the tightness degree of the neck is adjusted; the neckline tightening belt is also provided with a mechanism which is integrally connected with the whole protective clothing below.

The main body of the head cover can also be made into a cylinder shape, the diameter of the neck is larger than or equal to the diameter of the section of the part, the top is closed, a lower wearing port is arranged below the head cover, and a collar tightening band surrounding the neck is arranged along the edge; because the size of the lower wearing opening is large enough, other wearing openings are not needed to be opened.

The main body of the hood can be made of opaque materials, in this case, goggles are arranged on the front side of the hood and at the positions of eyes of a wearer; the frame of the goggles is made of elastic material and is sealed with the main body of the head cover by the existing protective suit seaming technology, the veneering part of the goggle frame adopts a rubber ring which is jointed with the shape of the face, the head of the goggle is encircled by a goggle fixing band to fix the goggles at a proper position, and meanwhile, the goggles can prevent sweat and moisture from entering the eyes; the tightness degree of the goggle fixing band can be adjusted through a fixing band adjusting port, and the fixing band adjusting port is internally provided with a lining for enhancing sealing; the goggles should be outwards convex, and the size is big enough to hold general spectacles for myopia, and the goggles fixed band inboard sets up the recess in order to hold the glasses leg.

The main body of the hood can also be made of transparent material; or divided into upper and lower half parts by taking the forehead of the wearer as a boundary, wherein the upper half part is made of opaque material, and the lower half part is made of transparent material. In this case, the inner visor is not required. The lower half part can be turned upwards and fixed at the top through a neckline tightening belt.

The hood main body can be provided with a food inlet at the mouth of a wearer, is a horizontal opening and is closed by a cover plate with a sticking zipper; the food inlet can provide convenience for the temporary food taking, water drinking and other behaviors of a user needing to wear the food inlet for a long time.

The head cap main body can be internally provided with a head-wearing electronic product; comprises a miniature camera arranged above the front side, and built-in wireless earphones (12) arranged at the two sides and the ear position of a wearer; the electronic products can be operated by a mobile phone program; the back side can be provided with a battery box to provide power supply for the head-wearing audio-visual equipment.

The main body of the head cover can be matched with a one-way exhaust valve. The matching can improve the air pressure and humidity conditions in the hood under the closed environment, so that the wearing is more comfortable.

The invention has the beneficial effects that: the utility model provides a respiratory protection hood, provides the wholeness protection to all organs of head, has improved the using-way of air filter material in respiratory protection device, has improved its economic nature and efficiency, has realized the used repeatedly of respiratory protection device main part, has increased respiratory protection device's suitability and humanized consideration to its intelligent function has been expanded.
