DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 7 As shown, the technical solution adopted in this specific embodiment is: it includes a fixed outer frame 3, a movable slot A is opened on the fixed outer frame 3, and an adjusting tension component 1 is installed at one end of the opening of the movable slot A, a fixed component 2 is provided at the other end of the opening of the movable slot A, a tourniquet 5 is installed on the fixed outer frame 3, and the adjusting tension component 1 includes a supporting shell 13, tourniquet through holes 15 are opened at both ends of the supporting shell 13, and a fixed card 16 is installed at the bottom of the inner cavity of the supporting shell 13, a card movable slot 19 is opened at the bottom of the inner cavity of the supporting shell 13, an adjusting button 11 is movably connected to the card movable slot 19, an active card 18 is installed on the adjusting button 11, and a protective top shell 12 is covered on the supporting shell 13, a limited movable slot 14 is opened on the protective top shell 12, and the adjusting button 11 cooperates with the limited movable slot 14.

[0023] More specifically, the position-limiting movable groove 14 is a movable groove that is wide at both ends and narrow in the middle, and the adjusting button 11 is interference-fitted with the middle of the position-limiting movable groove 14. When the adjusting button 11 is at both ends of the position-limiting movable groove 14, due to the interference fit between the adjusting button 11 and the middle of the position-limiting movable groove 14, the adjusting button 11 will not move unnecessarily.

[0024] More specifically, a leaf spring 17 is provided between the fixed card 16 and the inner wall of the supporting shell 13. The leaf spring 17 can enhance the elasticity of the fixed card 16, thereby increasing the service life of the fixed card 16.

[0025] More specifically, the fixing assembly 2 includes a movable shaft 22, which is mounted on the fixed outer frame 3 through a support bracket 21, a pressing handle 23 is fixedly connected to the movable shaft 22, and a fixing block 24 is installed on the inner side of the pressing handle 23. When the tourniquet 5 needs to be installed on the fixing assembly 2, the staff only needs to open the pressing handle 23, and then pass the tourniquet 5 from under the movable shaft 22, and then press the pressing handle 23, and use the fixing block 24 and the anti-slip protrusion 25 to press the tourniquet 5.

[0026] More specifically, an anti-skid protrusion 25 is installed at the lower end of the fixing block 24 to increase the stability between the fixing block 24 and the tourniquet 5 .

[0027] More specifically, an adhesive sheet 4 is installed between the inner side of the fixed outer frame 3 and the tourniquet 5. The adhesive sheet 4 is used to bond the fixed outer frame 3 and the tourniquet 5, which can ensure the stability between the fixed outer frame 3 and the tourniquet 5 to a certain extent.

[0028] The working principle of the utility model is as follows: when it is necessary to use the tourniquet 5, the medical staff only needs to insert the fixed outer frame 3 and the tourniquet 5 into the part of the patient where the bleeding is required, so that the part of the patient where the bleeding is required is located in the inner cavity of the fixed outer frame 3 and the tourniquet 5, and then, the tourniquet 5 can be pulled to complete the tightness adjustment of the tourniquet 5. When the tourniquet 5 is pulled, the fixed card 16 and the movable card 18 can engage the tourniquet 5 to prevent the tourniquet 5 from moving in the opposite direction and causing the tourniquet 5 to loosen. When it is necessary to loosen the tourniquet 5, the medical staff only needs to turn the adjusting button 11 so that the adjusting button 11 drives the movable card 18 to loosen the tourniquet 5, which is convenient for the medical staff to pull and loosen the tourniquet 5. Among them, when idle, the medical staff can first install the tourniquet 5 on the fixed component 2 to facilitate subsequent use.

[0029] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
