Intelligent hemostatic band and hemostatic method

Abstract

The invention discloses an intelligent hemostatic band. The intelligent hemostatic band comprises a hemostatic band body, a hemostatic controller is mounted on the front surface of the hemostatic bandbody, the hemostatic band body comprises a heat insulation layer and a gas permeable layer, and a shape memory alloy coil is wrapped in the heat insulation layer; the hemostatic controller comprisesa housing, a display screen, a microprocessor, a battery, a sound wave sensor, a timer and a switch; the switch and the sound wave sensor are separately connected to a corresponding input end of the microprocessor, the display screen is connected to a corresponding output end of the microprocessor, the shape memory alloy coil is connected to the corresponding output of the microprocessor through acontrol circuit, and the timer is connected to the microprocessor. The invention also discloses a hemostatic method by using the intelligent hemostatic band. According to the intelligent hemostatic band and the hemostatic method, the intelligentization degree is high, the hemostatic band can be automatically tightened and relaxed according to hemostatic conditions, manual operation is not required, the hemostatic safety and effectiveness are ensured, and the hemostatic band and the hemostatic method are easy to popularize in the market.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intelligent tourniquet and a hemostasis method. Background technique [0002] Whether it is emergency hemostasis or limb surgery, it is necessary to pressurize the limbs to stop bleeding, so as to save lives or create a bloodless incision to facilitate surgery. Usually, elastic tourniquets and inflatable tourniquets are used for hemostasis. [0003] The elastic tourniquet is made of rubber and is manually tightened on the necessary parts of the limbs. It can complete the simple and temporary hemostasis of the limbs, but it is inconvenient for a single person to operate and the hemostatic effect is not good. [0004] The inflatable tourniquet can pressurize the affected limb to stop bleeding through the preset inflation pressure. However, the inflation pressure is estimated by the doctor, and this pressure is not the appropriate arterial compression pressure. Compared with patie...

AI Technical Summary

Problems solved by technology

The pressurization pressure of the tourniquet is based on the arterial compression pressure of the limbs, which can ensure the safety and effectiveness of the tourniquet. The disadvantage is that when the gas is filled, the gas is easy to escape from the interface due to the excessive pressure in the tube, resulting in The pressure filled into the tourniquet air bag is difficult to meet the requirements of hemostasis, not only can not achieve the effect of hemostasis, but also delay the treatment of patients

[0006] In terms of tourniquet materials, traditional tourniquets generally directly contact the skin or are covered with other cloth materials, but these materials are not skin protection materials under high pressure, and serious complications such as skin pressure sores, blisters, necrosis, and even vascular and nerve damage often occur. disease
