An electric pneumatic hemostat

Abstract

The invention discloses an electropneumatic hemostat, comprising: a belt body; a first elastic belt attached to one end of the belt body; a second elastic belt attached to the other end of the belt body; A buckle, which is arranged between the first elastic strap and the second elastic strap, can surround the strap into a ring; a plurality of airbags, which are arranged inside the strap; an inflation device , which are respectively connected to the airbag through a plurality of ventilation tubes, and can inflate the airbag; the inflation flow valve, which is arranged on the ventilation tube, can control the inflation speed of the inflation device. The electric pneumatic hemostasis provided by the present invention The belt body is fixed by the self-tightening buckle, and the elastic belt can be wound through the reel, and the size of the belt body fixing ring can be changed arbitrarily. It is suitable for any part of the body and exerts pressure on the hemostat through the air bag. The invention also provides a control method of the electric pneumatic hemostat.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an electric pneumatic hemostat. Background technique [0002] Blood loss is a leading cause of death in emergencies, when the injured are alone or when medical help is not on the way. In such cases, the use of a tourniquet to stop the loss of blood from the injured arm or leg is known to stop the bleeding. Often in an emergency, when the injured person is alone, he or she must use only one hand to apply a tourniquet to stop the blood flow to an arm or leg. A typical tourniquet is a bandage that is tightly tied or wrapped around a limb such as an arm or leg in an attempt to stop severe bleeding or bleeding in emergency situations. [0003] The patent application document with application number 201480029113.2 discloses a tourniquet that is light, compact, and suitable for one-handed operation. However, the fixing effect and pressure of the tourniquet still need to be applied b...

[0003] The patent application document with application number 201480029113.2 discloses a tourniquet that is light, compact, and suitable for one-handed operation. However, the fixing effect and pressure of the tourniquet still need to be applied by medical staff, and it is difficult to precisely control it

[0004] The patent application document with the application number 201510506510.0 discloses a tourniquet provided by the present invention. By adopting a special gas generating device, the inflation operation only needs to be pressed once. The operation is very convenient, and the inflation time is short. to 1 second, but the platen is prone to position changes during inflation

Detrimental to pressure control of the tourniquet
