The push rod 60 is pushed, and the push rod 60 can push the piston rod 40 to move in the direction close to the head of the syringe 10, and the piston 50 will also move in the direction close to the head of the syringe 10, so that the piston 50 pushes the hemostatic gel 30 to move in the direction close to the membrane cover 11, and the hemostatic gel 30 can squeeze the membrane cover 11, and the hemostatic gel 30 will reach the roller 20. The hemostatic gel 30 is applied to the part to be hemostatic by the roller 20, so as to help improve the uniformity of the hemostatic gel applied to the part to be hemostatic, so that the part to be hemostatic can stop bleeding quickly and effectively. Furthermore, the hemostatic gel 30 is applied to the part to be hemostatic by the roller 20, and the hemostatic area of the hemostatic device can also be increased, so as to achieve effective hemostasis when the bleeding point is unclear.

The hemostatic gel 30 is applied to the part to be hemostatic by the roller 20, which helps to improve the uniformity of the application of the hemostatic gel to the part to be hemostatic, so that the part to be hemostatic can stop bleeding quickly and effectively. Furthermore, by applying the hemostatic gel 30 to the part to be hemostatic by the roller 20, the hemostatic area of the hemostatic device can also be increased, so as to achieve effective hemostasis when the bleeding point is unclear.
[0054] It should be noted that in the embodiment of the utility model, the first connecting member 70 is fixedly connected to the position of the injection tube 10 close to the head and the second connecting member 80 is fixedly connected to the position of the injection tube 10 close to the head, wherein the fixed connection means that the first connecting member 70 and the second connecting member 80 do not move relative to the injection tube 10.

[0059] In some embodiments, along the extension direction of the injection tube 10, there is a first distance L between the head of the injection tube 10 and the roller 20, satisfying 0.2cm≤L≤1cm.
[0060] like Figure 1 , Figure 3 and Figure 4As shown, along the extension direction of the injection tube 10, there is a first distance L between the roller 20 and the head of the injection tube 10. In the embodiment of the utility model, the first distance L is set to be greater than or equal to 0.2 cm to prevent the roller 20 from blocking the head of the injection tube 10, resulting in the hemostatic gel 30 being unable to flow out of the head of the injection tube 10, affecting the normal use of the hemostatic device. The first distance L is set to be less than or equal to 1 cm to prevent the roller 20 from being too far from the head of the injection tube 10, resulting in the hemostatic gel 30 being unable to reach the roller 20, and the hemostatic device cannot be used normally.
[0061] Exemplarily, along the extension direction of the injection tube 10, the first distance L between the head of the injection tube 10 and the roller 20 can be set to 0.2 cm, 0.4 cm, 0.6 cm, 0.8 cm, 1 cm, etc.
