Description

New protective mask to prevent infection

Technical field

The utility model belongs to the technical field of medical devices, and specifically relates to a new protective mask for preventing infection.

Background technique

When medical staff conduct face-to-face examinations on patients, the patients may produce droplets, aerosols, etc. due to open respiratory tracts or coughs, which may lead to the spread of the virus. In order to avoid infection of medical workers, medical workers should wear corresponding protective equipment, such as protective clothing, protective masks, etc. when performing relevant operations. The protective mask is a type of respiratory protective equipment that prevents cross-infection and the spread of bacteria through the mouth and nose.

At present, protective masks used at work usually consist of a mask body and an elastic fixing clip fixed on the mask body. Although this structure is simple and easy to wear, it also has certain shortcomings during use. That is, when users with different head circumferences wear masks, the range of head circumferences applicable to the elastic fixing clip is relatively narrow. If the head circumference is too large, wearing the mask for a long time will easily cause the head to be clamped and clamped by the fixing frame. Squeezing may cause pain; if the head circumference is too small, it will be difficult to fix the mask while wearing it, causing the mask to slip.

Utility model content

The utility model aims to solve the above problems and provides a new protective mask for preventing infection.

The utility model is realized through the following technical solutions: a new protective mask for preventing infection, which is characterized in that it includes a fixed belt, a support frame is provided in the middle of the fixed belt, and the mask body is detachably installed on the front side of the support frame , the upper end of the mask body is provided with a square hole, and the support frame is provided with an L-shaped hook. The mask body can be detachably hung on the L-shaped hook through the square hole; one end of the fixed belt is provided with a plurality of The limit hole has a plurality of fixed buckles at the other end. The fixed buckles are buckled in the limit hole. Each fixed buckle includes a connecting column installed on the fixed belt. The rear end of the connecting column is provided with a limiting stop. The block has a plurality of anti-slip rings at the front end; a plurality of ventilation holes are also provided on both sides of the fixed belt.

Furthermore, both the support frame and the mask body adopt an arc-shaped structure adapted to the curvature of the human face.

Furthermore, the fixing straps and fixing buckles are made of silicone material.

Furthermore, the fixing strap and the support frame are connected by bonding.

The beneficial effects of this utility model are:

1. In this new type of use, multiple limit holes and fixed buckles are provided at the end of the fixed belt, and the fixed buckles are adjusted to buckle in different limit holes to adjust the overall fixing range of the fixed belt so that it can be applied to Users with different head circumferences can avoid the squeezing of the head caused by long-term wearing, which improves the user's wearing comfort. In addition, the fixed strap is made of silicone material and has a good anti-slip effect.

2. This utility model detachably installs the mask body on the support frame through a square hole, which effectively prevents cross-infection, and only needs to replace the mask body during replacement, saving usage costs.

Detailed ways

In order to make the purpose, technical solutions and beneficial effects of the present utility model more clear, the technical solutions in the present utility model will be further described below in conjunction with the embodiments.

As shown in Figures 1 to 5, a new type of protective mask for preventing infection includes a fixed belt 1. A support frame 2 is provided in the middle of the fixed belt 1, that is, the fixed belt 1 is bonded to the support frame 2, and the mask body 4 is detachable. type is installed on the front side of the support frame 2, that is, only the mask body 4 is replaced during replacement, which saves usage costs. A square hole 5 is provided at the upper end of the mask body 4, and an L-shaped hook 3 is provided on the support frame 2, through which the mask body 4 passes The square hole 5 is detachably hung on the L-shaped hook 3; one end of the fixed belt 1 is provided with a plurality of limit holes 7, and the other end is provided with a plurality of fixing buckles 8. Generally, the fixing buckles 8 are 2-4, the fixed buckle 8 is buckled in the limit hole 7, that is, by adjusting the position of the fixed buckle 8 in the limit hole 7, the size of the fixed belt 1 can be adjusted. Each fixed buckle 8 includes a connecting column 82 installed on the fixed belt 1. The rear end of the connecting column 82 is provided with a limit stop 81 to prevent the connecting column 82 from sliding off the fixed belt 1. The front end is provided with a plurality of anti-slip rings. 83. The anti-slip ring 83 closest to the fixed belt 1 is used to prevent the connecting column 82 from sliding off the fixed belt 1. The outer anti-slip ring 83 is used to prevent the connecting column 82 from being connected after inserting the connecting column 82 into the limiting hole 7. The post 82 slips out of the limiting hole 7 . In order to improve the comfort of the device, a plurality of ventilation holes 6 are provided on both sides of the fixing belt 1 .

In order to improve the wearing comfort of the user, both the support frame 2 and the mask body 4 adopt an arc-shaped structure adapted to the curvature of the human face.

In order to increase friction and prevent the device from sliding down from the head, the fixing strap 1 and the fixing buckle 8 are made of silicone.

When in use, buckle the mask body 4 on the support frame 2, then wrap the fixing strap 1 around the user's head, select the appropriate limit hole 7 according to the size of the user's head, and buckle the fixing buckle 8 on the limit hole 7 Inside, the device is fixed on the user's head. At this time, the mask body 4 can effectively prevent external germs from spreading through the mouth and nose and avoid cross-infection.

Except for the technical features described in the description, the remaining technical features are known to those skilled in the art.
