Description

Mask for operating room care

technical field

The utility model belongs to the technical field of medical auxiliary supplies, in particular to a mask for nursing in an operating room.

Background technique

Medical staff in operating rooms often wear masks to avoid cross-infection with patients, but commonly used masks can only filter out dust particles in the air, but have no blocking effect on viruses and bacteria in the air.

Viruses and bacteria particles are very small, generally less than 0.3 microns in diameter. The masks currently used, whether they are medical masks (represented by various types of surgical masks from 3M in the United States) or ordinary civilian masks, are all made of textiles. . The fabric mesh of the mask is ineffective at isolating viruses and bacteria floating in the air. Despite this, masks are still commonly used in hospitals, because wearing masks can block the spread of liquid droplets in the mouth and nasal cavity, and can prevent dirty hands from accidentally touching the mouth and nose, bringing bacteria or viruses into the human body. If it is required to filter out bacteria and viruses in the air, it is necessary to add multiple layers of microporous filtration to the mask, resulting in poor airflow; or a bulky external filter tank is required to make a fully enclosed respirator to ensure airtightness, such as the current Gas masks, etc., kill bacteria and viruses in the air through the mercury lamp built in the filter tank, and then deliver the sterilized gas to the mask for inhalation by the human body. This mask and respirator will bring many inconveniences during use, such as: difficulty in breathing, because the main air flow channel needs to be filtered layer by layer to cause air flow is not smooth, the user has difficulty breathing, in addition, once the mask or respirator is in contact with the user's If the face is not tightly combined, it is easy to leak air from the side, let alone filter bacteria and viruses.

Therefore, it is necessary to develop a new mask for operating room care, so that it can block viruses and bacteria while allowing the user to breathe smoothly.

Detailed ways

The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

An operating room nursing mask, as shown in Figures 1-3, comprises a mask body and hanging straps 1 symmetrically arranged on both sides of the mask body, and the hanging straps 1 are hung on the user's ears to fix the mask body in use face of the victim.

The mask body is composed of 3-5 layers of gauze that are stacked sequentially from the outside to the inside. The nose of the mask body, that is, the position corresponding to the user's nose, is provided with a rectangular through hole, and the outside of the rectangular through hole is provided with a first filter layer. 2. One side of the first filter layer 2 is movably connected to the outside of the mask body through the first Velcro, and the other three sides are fixedly connected to the outside of the mask body. A second filter layer 3 is provided on the inside of the rectangular through hole. The four sides of the second filter layer 3 are all fixedly connected to the inside of the mask body; a placement cavity with an open end is formed between the first filter layer 2, the rectangular through hole and the second filter layer 3, and a filter sheet 4 is placed in the cavity. And the filter sheet 4 covers the rectangular through hole. When in use, one side of the first filter layer 2 is opened with the first velcro that is connected to the outside of the mask body, the filter sheet 4 is put into the placement cavity, and then the first velcro is closed to make the placement cavity in a closed state to prevent The polluted air is directly absorbed by the human body without being processed by the mask body. Moreover, this movable setting method can also replace the filter sheet 4 at any time, activate or directly replace the filter sheet 4 that is saturated or invalid and then put it into the placement cavity.

The filter sheet 4 includes a honeycomb activated carbon filter layer 5, a nano-silver bactericidal layer 6 and a drying layer 7 arranged sequentially from the outside to the inside. The honeycomb activated carbon filter layer 5 can adsorb particulate matter in the air, and the nano-silver bactericidal layer 6 Bacteria and viruses in the air can be killed, while the drying layer 7 can absorb the moisture in the exhaled air of the human body to keep the mask body dry, which not only avoids the growth of bacteria in a humid environment, but also makes the user feel comfortable.

It should be noted that the thickness of the honeycomb activated carbon filter layer 5 is 1mm, and the aperture of the filter hole on the honeycomb activated carbon filter layer 5 is 10 μm; the nano-silver bactericidal layer 6 is a gauze layer coated with nano-silver; the dry layer 7 It is a highly water-absorbing and hygroscopic fiber layer, and the micropore diameter on the highly water-absorbing and hygroscopic fiber layer is 10 μm. The honeycomb activated carbon filter layer 5 can absorb particulate matter in the air in the mask body, the nano-silver sterilizing layer 6 can kill viruses and bacteria in the air, and the drying layer 7 can absorb the moisture in the exhaled air of the human body to keep the mask The dryness of the main body not only avoids the growth of bacteria in a humid environment, but also makes the user feel comfortable.

In addition, since the honeycomb activated carbon filter layer 5, the nano-silver sterilizing layer 6, and the micropores on the drying layer 7 have relatively large apertures, the air enters smoothly, thereby enabling the user to breathe smoothly.

A metal nose clip 8 is arranged on the top of the rectangular through hole in the mask itself. The metal nose clip 8 can separate a certain distance between the corresponding part of the nose on the mask body and the user's nose, so that the user feels comfortable and can breathe freely. .

The mouth position of the mask body, that is, a circular through hole 9 is provided at the corresponding place of the user's mouth, and a cover 10 is provided on the outside of the circular through hole 9, and the circular through hole 9 and the cover 10 pass through the second Velcro. Cover the connection. A straw can be inserted in the circular through hole 9. During the operation, if the medical personnel want to drink water, they need to take off the mask. This experiment is equipped with a circular through hole 9. If the medical staff drinks water during the operation, they only need to lift the cover 10 and insert the straw into the circular through hole 9 to drink water, which minimizes the medical staff's breathing and droplets. Bacteria to the infection that patient's wound causes, drink water and cover body 10 and get final product, use very convenient.

A soft polysilicone foam strip 11 is provided around the inner side of the mask body. The soft polysilicone foam strip 11 can absorb the cheeks well, prevent polluted air from entering from the side, and has good sealing performance.

In the utility model, the above disclosures are only specific embodiments of the utility model, but the utility model embodiment is not limited thereto, and any changes that those skilled in the art can think of should fall into the protection of the utility model scope.
