Further, referring to fig. 1-4, based on the above, when the bottom layer 120 is disposed, in order to facilitate the chitosan hemostatic sponge layer 130 connected to the bottom layer 120 to be attached to the place to be hemostatic, the bottom layer 120 is adhered to one end of the elastic band 110 along the extending direction of the elastic band 110. In this way, the connection between the first connection portion 111 and the second connection portion 112 can be facilitated, and the use of the tourniquet 100 can be facilitated.

In this embodiment, when the first connecting portion 111 and the second connecting portion 112 are disposed, the first connecting portion 111 and the bottom layer 120 are located at the same end of the elastic band 110 and are respectively located at two side surfaces of the elastic band 110; and the second connection portion 112 is located at the other end of the elastic band 110. Furthermore, the first connection portion 111 and the second connection portion 112 may be connected by bonding, such as: the first connection portion 111 and the second connection portion 112 may be adhered by a hook and loop fastener; specifically, the first connecting portion 111 is a hook and loop fastener burr, and the second connecting portion 112 is a hook and loop fastener burr; or, the first connecting portion 111 is a hook and loop fastener, and the second connecting portion 112 is a hook and loop fastener.

In the process of connecting the first connecting portion 111 and the second connecting portion 112, in order to facilitate the adjustment of the position of the elastic band 110 according to different patients and the adjustment of the amount of pressure applied to the compression pad 121 by the elastic band 110, the length of the first connecting portion 111 is smaller than the length of the second connecting portion 112 along the extending direction of the elastic band 110.
