Description

Technical Field

[0001] The utility model relates to the technical field of hemostatic instruments for medical emergency use, in particular to a hemostatic device. Background Art

[0002] In medical emergencies, hemostasis is an indispensable part of the first aid process. For patients with severe bleeding, first aid requires hemostasis treatment through bandaging and pressing. When the patient has arterial bleeding, pressure needs to be applied to the proximal end of the bleeding site to slow down the blood flow in the blood vessels, and the wound needs to be bandaged to improve the efficiency of hemostasis.

[0003] In existing medical emergencies, when performing hemostatic treatment on patients with severe limb bleeding, common compression methods are to use elastic rubber bands or manually press the limbs. During the manual compression process, a single medical staff member or patient needs to perform the compression operation for a long time, which can easily cause fatigue, and requires the cooperation of multiple people to perform compression and bandaging. When using rubber bands for compression and binding, due to the certain elasticity of the rubber bands and the high binding requirements, experienced medical staff are required to operate, resulting in low binding efficiency and unfavorable for the rapid implementation of emergency work. Utility Model Content
