The medical cotton layer is filled with hemostatic and disinfectant, and the pressing part 200 can be designed at one time in order to save resources and avoid infection; when in use, the pressing part 200 is replaced, so that the pressing part 200 can press the puncture hole to stop bleeding, when another patient needs to use, the pressing part 200 can be replaced and reused, and of course, the installation position of the pressing part 200 also needs to be disinfected properly.
The body 100 is provided with an elastic expansion piece 10 and a connecting piece 20; the elastic expansion piece 10 can reflect the tensile force applied to the body 100, and the connecting piece 20 is convenient to wear and can also realize the adjustment of the inner diameter of the body 100;
the first part 101 and the second part 102 of the body 100 are connected through an elastic expansion piece 10;
the elastic expansion piece 10 comprises an elastic part 11 and a stretching part 12; the elastic part 11 is positioned in the accommodating groove of the first part 101, and one end of the stretching part 12 away from the elastic part 11 is connected to the second part 102;
the body 100 is connected at both ends by a connecting member 20.
In connection with fig. 2, the stretching portion 12 is provided with a pull scale 120, and the pull scale 120 is used for representing the pulling force applied to the elastic portion 11.
When the stretching part 12 is pulled out, the elastic part 11 is stretched and deformed, so that the outward pulling distance of the stretching part 12 is in a linear relation with the pulling force applied to the elastic part 11; the tensile force is proportional to the stretched length of the elastic portion 11, calculated from F ═ kx.
For example, when the 4 th gear pulling force is required, the pulling portion 12 is pulled out from the receiving groove, and when the 4 th gear is flush with the lower end surface of the first portion 101, the pulling force applied to the elastic portion 11 reaches the 4 th gear pulling force value. As shown in fig. 3, the connector 20 includes a male connector 21 and a female connector 22, and the connection length of the male connector 21 and the female connector 22 can be adjusted.
As shown in fig. 3, the end of the male connection head 21 away from the body 100 is provided with a connection groove 210, and the end of the female connection head 22 away from the body 100 is provided with a connection portion 220.
