Problems solved by technology

[0006] In order to overcome the deficiencies of existing masks such as insufficient protection, unscientific use of air filter materials, and ultra-low service life, the present invention provides a medical respiratory protection device, which uses a hood to protect all organs of the head as a whole, and at the same time reduces the size of the air filter. The use area of ​​the material is reduced, and the air filter material is made into a module box independent of the main body of the hood. The main body of the hood can be cleaned and disinfected after the air filter module is removed, so that it can be reused

Embodiment 1

[0040] See attached figure 1 , attached figure 2 , attached image 3 , The respiratory protective headgear of this embodiment includes a headgear main body (1) and an air filter module (2).

[0041] The main body of the hood (1) adopts the same material as the existing medical protective clothing, and adopts a shape conforming to the shape of the head to wrap all the head organs, and the diameter of the neck is smaller than the section diameter of the above part; The wearing mouth (7) has a vertical wearing mouth (8) at the rear; the upper end of the vertical wearing mouth (8) is fixed, and the lower end can be opened, so that the headgear can be opened in an inverted V shape; the vertical wearing mouth (8) passes through The pasted zipper is closed; the pasted zipper has a certain width, and the wearer can thus adjust the overall tightness of the hood; the lower end of the vertical wearing mouth (8) is fixed with a neckline drawstring (9) on both sides, crossing around the...

Embodiment 2

[0049] See attached Figure 4 , The respiratory protective headgear of this embodiment includes a headgear main body (1) and an air filter module (2).

[0050] The main body (1) of the hood is made of a cylinder, the diameter of the neck is greater than or equal to the section diameter of the above part, the top is closed, the lower end is provided with a wearing opening (7) below, and a rope-type neckline drawstring (9) around the neck is provided along the edge. ), thereby closing the hood main body (1), and adjusting the degree of tightness of the neck; because the lower end wearing mouth (7) size is large enough, it is not necessary to open other wearing mouths.

[0051] The main body (1) of the hood is divided into upper and lower parts with the wearer's forehead as the boundary, wherein the upper part is made of existing protective clothing materials, and the lower part is made of soft, high-strength, high-toughness transparent material with a certain thickness. Plastic...

Abstract

The invention discloses a respiratory protection head cover. The respiratory protection head cover comprises a head cover main body and an air filtering module, wherein the head cover main body is a protective device made of an airtight soft material and covers the whole head, and the air filtering module is a module box made of an air filtering material and exactly covers a nose area; the modulebox can be connected with or separated from the head cover main body at a breathing opening through a connecting mechanism, and the head cover main body can be cleaned and disinfected after being separated from the air filtering module, and therefore the head cover main body can be repeatedly used; the head cover main body is further provided with a connecting mechanism connected with other protective devices, and head-mounted electronic equipment can be configured according to needs. According to the respiratory protection head cover, all head organs are integrally protected, the using mode of the air filtering material in a respiratory protection device is improved, so that the economical efficiency and efficiency of the respiratory protection head cover can be improved; and meanwhile, arespiratory protection device main body can be repeatedly used, applicability and humanization consideration of the respiratory protection device are improved, and therefore an intelligent function of the respiratory protection head cover can be expanded.

Description

technical field [0001] The invention relates to a respiratory protection device, in particular to a medical respiratory protection device. Background technique [0002] Existing medical respiratory protection device mainly is mouth mask. However, masks have obvious defects in the following aspects: [0003] 1. It cannot provide protection for organs other than the mouth and nose. The recent raging novel coronavirus pneumonia has made people deeply aware that airborne diseases are likely to be transmitted not only through the mouth and nose, but also through the eyes and even other facial organs; therefore, masks alone can no longer meet the new respiratory protection requirements. Even if the mask is used in combination with a protective mask or protective goggles, there are problems; the main problem is that because this combination cannot form an overall protective system, there will be obvious protective loopholes at the joint, for example, there is a gap between the me...
