Description

Technical Field

[0001] The utility model relates to the field of masks, in particular to a medical surgical mask. Background Art

[0002] Medical surgical masks are used to be worn on the mouth and nose of medical staff in the operating room to prevent the spread of dandruff and respiratory microorganisms to open surgical wounds, and to prevent the spread of body fluids from surgical patients to medical staff, playing a role of two-way biological protection. Ear-loop masks will tighten the ears if worn for a long time, so head-mounted masks are used during surgical operations. Most head-mounted masks now have four straps that are tied behind the head, but they require help from others to fasten. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the utility model provides a medical surgical mask.

[0004] The technical solution of the utility model is achieved as follows: a medical surgical mask comprises a mask body, wherein a first ear strap and a second ear strap are respectively provided on both sides of the length direction of the mask body, the number of the first ear strap and the second ear strap are both 2, the end of the first ear strap is fixedly connected to the first fixing part, the end of the second ear strap is fixedly connected to the second fixing part, the first fixing part cooperates with the second fixing part, the first fixing part comprises a rectangular buckle, the rectangular buckle is a cavity structure, one end of the rectangular buckle is fixedly connected to the first ear strap, the other end of the rectangular buckle is an opening structure, a through hole 1 is provided on the top plate of the rectangular buckle, the second fixing part comprises a clip, the clip is a cavity structure, a through hole 2 is provided on the top plate of the clip, the top surface of the bottom plate of the clip is fixedly connected to a vertically arranged spring, and the top of the spring is fixedly connected to a card block.

[0005] The size of the opening at the end of the rectangular buckle is adapted to the size of the buckle.

[0006] The clamping block extends upward to the outside of the second through hole.

[0007] The card block matches with the through hole one.

[0008] The bottom of the clamping block is circumferentially fixedly connected with a limiting plate, and the limiting plate is located below the second through hole.

[0009] The technical solution of the utility model has the following positive effects: the mask body of the utility model is respectively provided with a first ear strap and a second ear strap, and the number is two; when worn on the back of the head, the first ear strap and the second ear strap are fixed to each other, and can be worn crosswise or horizontally; the second ear strap and the second ear strap are fixed by providing the first fixing part and the second fixing part, which can be done by one person and is easy to use; the limiting plate limits the vertical part of the buckle.

[0014] like Figure 1-4 As shown, a medical surgical mask includes a mask body 1, and a first ear strap 2 and a second ear strap 3 are respectively provided on both sides of the length direction of the mask body 1, and the number of the first ear strap 2 and the second ear strap 3 is 2. The end of the first ear strap 2 is fixedly connected to the first fixing part, and the end of the second ear strap 3 is fixedly connected to the second fixing part. The first fixing part cooperates with the second fixing part. The first fixing part includes a rectangular buckle 4, which is a cavity structure. One end of the rectangular buckle 4 is fixedly connected to the first ear strap 2, and the other end of the rectangular buckle 4 is an open structure. A through hole 1 is provided on the top plate of the rectangular buckle 4. The second fixing part includes a buckle 6, which is a cavity structure. A through hole 2 is provided on the top plate of the buckle 6. The top surface of the bottom plate of the buckle 6 is fixedly connected to a vertically arranged elastic Spring 8, the top of the spring 8 is fixedly connected with a card block 9; specifically, this mask is a head-worn mask, the first ear strap 2 and the second ear strap 3 are fixed, and can be crossed with each other or connected horizontally, and the first fixing portion of the first ear strap 2 is fixed to the second fixing portion of the second ear strap 3. The specific operation steps are to insert the buckle 6 from the opening at the end of the rectangular buckle 4. When inserted, the card block 9 is pressed down and the spring 8 is compressed. When the card block 9 enters the position of the through hole 1 5, the compressed spring 8 recovers its deformation and pushes up the card block 9, so that the card block 9 comes out of the through hole 1 5, thereby fixing the first ear strap 2 and the second ear strap 3. The shapes of the through hole 1 5 and the through hole 2 7 are not limited. In this embodiment, a circle is used, and the corresponding cross-sectional shape of the card block 9 is also a circle.

[0015] The size of the opening at the end of the rectangular buckle 4 is adapted to the size of the buckle 6 ; specifically, the buckle 6 must be able to enter from the opening at the end of the rectangular buckle 4 .

[0016] The clamping block 9 extends upward to the outside of the second through hole 7 .

[0017] The clamping block 9 matches with the through hole 1 5 ; specifically, the clamping block 9 should be able to go out from the through hole 1 5 .

[0018] The bottom of the clamping block 9 is circumferentially fixedly connected with a limiting plate 10 , which is located below the second through hole 7 ; specifically, the limiting plate 10 limits the vertical direction of the clamping block 9 .
