Embodiment 1

[0031] Such as Figure 1-2 As shown, a medical anti-aerosol protective headgear of this embodiment includes a head fixing device 1, a face screen 2 and a head cover 3, and the head fixing device 1 corresponds to the forehead and the inner sides of both sides of the forehead in the front half There are spaced flexible support devices 4, and the surface of the flexible support device 4 that does not contact the head fixing device has several recesses 41 distributed at intervals to form protrusions 42 between adjacent recesses 41, so that the flexible support The devices 4 are distributed at intervals, so that when in use, the user's head only touches the protrusion 42 of the flexible support device, which is soft and comfortable, and has the function of absorbing sweat, while the recesses 41 are not close together, which relieves the user from stuffiness and sweating.

[0032] The flexible supporting device is thickened. Specifically, the size of the flexible supporting device 4...

Embodiment 2

[0038] Such as image 3 As shown, a medical anti-aerosol protective headgear of this embodiment includes a head fixing device 1, a face screen 2 and a head cover 3, and the head fixing device 1 corresponds to the forehead and the inner sides of both sides of the forehead in the front half There are flexible support devices 4 at intervals, and the head restraint device 1 is connected with a horizontally outwardly protruding support frame 9 on the outside of the front half corresponding to the forehead and both sides of the forehead.

[0039] In this embodiment, the flexible support device 4 is thickened. Specifically, the size of the flexible support device is: the total length is 20cm-28cm, the thickness is 3.0cm-5.0cm, preferably 3.0cm-4.0cm per piece The length of the flexible supporting device is 2.5cm-5.0cm, the width of the recess is 0.5cm-1.0cm, and the depth of the recess is 1.5cm. Therefore, when in use, the user's head only touches the protrusion 42 of the flexible s...

Abstract

The invention discloses a medical anti-aerosol protective hood. The protective hood comprises a head fixing device, a face screen and a hood, the head fixing device is provided with spaced flexible supporting devices on the front half part corresponding to the forehead and the inner sides of the two sides of the forehead; the flexible supporting devices are spaced and thickened, and / or the outer sides, corresponding to the forehead and the two sides of the forehead, of the front half portion of the head fixing device are connected with supporting frames which horizontally protrude outwards orobliquely protrude downwards. The surface screen is detachably fixed on the head cover or the head fixing device; after the head cover is fixed, the flexible supporting devices and / or the supporting frame indirectly or directly support the face screen, a ventilation space limited by the face screen and located in front of the head of a user is formed in the head cover, an air conveying pipeline connected with an external fan is arranged in the head cover, and / or a plurality of ventilation windows with ventilation holes are arranged on the head cover. The breathable space in front of a wearer is increased, aerial fog is prevented from appearing on the face screen, and the functionality and comfort of the closed hood are improved.

Description

technical field [0001] The invention relates to a surgical protective article, in particular to a medical anti-gas mist protective headgear. Background technique [0002] During clinical operations, medical staff face the risk of infection of various infectious diseases (such as hepatitis B, hepatitis C, AIDS, etc.), and the patient's blood / body fluid / cells, etc., have long-term medical operations (such as surgery) poses a huge threat to the health of medical staff.
