Description

A protective headgear for fixing a ventilator mask

Technical Field

The utility model relates to the technical field of medical instruments, and specifically relates to a protective headgear used for fixing a ventilator mask.

Background Art

The ventilator mask fixing headgear currently used is made of inelastic nylon material, with three nylon buckles extending from the forehead and the left and right ears, connected to the mask. By adjusting the tightness of the three nylon buckles, the mask is fixed and pressed to ensure that the mask is firmly attached to the face and the mechanical ventilation effect of the ventilator is guaranteed. In this fixing method, the three nylon buckles are connected to the mask through the forehead and the left and right ears. When the mask is pressed, it will bring pressure to the head, the sides of the ears and the cheeks on both sides, causing pain to the patient, and even long-term compression will cause medical device-related pressure injuries. For this reason, a protective headgear for fixing a ventilator mask is proposed.

The utility model provides the following technical solutions: a protective headgear for fixing a respirator mask, comprising a head fixing cover assembly 1, the upper part of the head fixing cover assembly 1 corresponds to the forehead, and the upper part of the head fixing cover assembly 1 is symmetrically fixedly connected with a forehead fixing belt 2, and the forehead fixing belt 2 is fixed to the wearer's forehead. The two symmetrical forehead fixing belts 2 are respectively worn on both sides of the wearer's forehead. Compared with the existing vertical pressure belt, it is more comfortable to wear and also makes the pressure on the forehead part evenly distributed, thereby reducing the relatively large pressure on a certain part of the forehead. The lower part of the head fixing cover assembly 1 corresponds to the lower jaw, and the lower part of the head fixing cover assembly 1 is symmetrically fixedly connected with a lower jaw fixing belt 3, and the lower jaw fixing belt 3 is fixed on both sides of the wearer's lower jaw. The outer wall of the forehead fixing belt 2 is provided with a first adhesive patch and a first adhesive seat 4, and the outer wall of the lower jaw fixing belt 3 is provided with a second adhesive patch and a second adhesive seat 5. The belt 2 crosses the connecting ring of the upper part of the respirator mask, and the lower jaw fixing belt 3 crosses the connecting ring of the lower part of the respirator mask. When wearing the protective head cover, first align the respirator mask with the mouth and nose of the wearer, and fix the forehead fixing belt 2 to the forehead of the wearer through the first bonding and the first bonding seat 4, and then fix the lower jaw fixing belt 3 to both sides of the wearer's lower jaw through the second bonding and the second bonding seat 5, so that the head fixing cover assembly 1 is fixed to the back of the wearer's head, and the respirator mask is fixed to the wearer's mouth and nose. The wearing method of the protective head cover fixes the respirator mask on both sides of the forehead and the lower jaw, and the dimension of the fixing belt is adjustable. When the respirator mask is pressed tightly, it will not bring greater pressure to the forehead or the periphery of the ears or a certain part of the cheek. The head fixing cover assembly 1 is used in combination with the fixing belt to be firmly worn and more comfortable to wear. The head fixing cover assembly 1 has a more comprehensive wrapping property for the back of the head, so that the head cover is firmly fixed as a whole, and the pressure on the back of the head is also reduced to a certain extent.

Specifically, the head fixing mask assembly 1 includes a head fixing belt group and an outer cover surface 101. The head fixing belt group and the outer cover surface 101 are detachably connected. The head fixing belt group fits the wearer's head. According to usage needs, the outer layer mask 101 can be removed and only the head fixing belt group is retained.
