Description

A kind of mask for magnetic resonance examination

Technical field

The utility model relates to the technical field of masks, in particular to a mask for magnetic resonance examination.

Background technique

A mask is a sanitary and anti-epidemic product. It is generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper and other materials. , currently in the medical field, in order to reduce the spread of bacteria and personal hygiene and safety, general medical staff and patients are required to wear masks. Current masks are mainly composed of non-woven fabrics, elastic ropes and metal battens. The metal battens can ensure the edge of the mask It fits the face closely to reduce the spread of bacteria. However, during the patient's magnetic resonance examination, we found that the metal wires in the mask affected the magnetic resonance examination.

After searching, according to the patent number "CN214509577U", a special mask for nuclear magnetic resonance is provided, which involves the technical field of medical supplies and solves the technical problem in the existing technology that the metal strips in the mask may harm the patient during nuclear magnetic resonance. The device includes a mask body and a skin fitting part, wherein the mask body is connected to the skin fitting part. It is used to cover the user's mouth and nose to prevent the user from inhaling germs.

The above-mentioned magnetic resonance masks mainly use elastic cords to fit the mask to the face. However, when fitting through elastic cords, we found that the fit is prone to incompleteness. At the same time, the pressure of the elastic cords affects the wearer's comfort and cannot To meet the current requirements for magnetic resonance masks, we have designed a mask for magnetic resonance examinations.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

The utility model provides a mask for magnetic resonance examination as shown in Figures 1-5, including a mask body 1. The top and bottom of the front of the mask body 1 are fixed with fixed sleeves 2, between the two fixed sleeves 2 The sleeve is connected with an elastic band 3. A jack 6 is provided on the top of the mask body 1. A plastic nose bridge strip 7 is connected to the inside of the jack 6. The tops of both sides of the back of the mask body 1 are fixed with release adhesive pieces 4. Release paper 8 is adhered to the surface of the release adhesive sheet 4 .

According to Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5,

The mask body 1 is composed of a first non-woven fabric layer 9, a melt-blown fabric layer 10, a filter cotton layer 11 and a second non-woven fabric layer 12. The filter cotton layer 11 is bonded to the top of the second non-woven fabric layer 12. The top of the cotton layer 11 is bonded with the melt-blown cloth layer 10, and the top of the melt-blown cloth layer 10 is bonded with the first non-woven fabric layer 9. Through the four-layer structure design, the protective performance of the mask body 1 is improved.

The size of the plastic nose bridge strip 7 is the same as the size of the socket 6, so that the plastic nose bridge strip 7 can be stably placed inside the socket 6. The plastic nose bridge strip 7 is a flexible silicone strip.
