Composite human body lower limb body surface pressure sensor and using method thereof

Abstract

The invention discloses a composite human body lower limb body surface pressure sensor, which comprises a first composite sensor, two second composite sensors, three third composite sensors and a fourth composite sensor. Each of the first composite sensor, the second composite sensor, the third composite sensor and the fourth composite sensor is composed of an upper film sensor, a sponge material,a Bluetooth transmitter and a lower film sensor, and the upper film sensor, the sponge material and the lower film sensor are fixedly connected in sequence from top to bottom. The Bluetooth transmitter is embedded in the sponge material. The pressure actually generated when the bandage surrounds the limb for a circle can be reflected, the local pressure under the sensor can be detected to be in asafe range, the individual difference of operators experiencing pressure application is avoided, and the problems that the elasticity of the elastic bandage is reduced after multiple times of use andthe pressure is inaccurate after operation according to a surface pressure mark are also avoided, and the curative effect and safety of pressurization treatment are improved.

Description

Technical field [0001] Technical Field The present invention relates to medical devices and more particularly relates to a composite body, the lower extremity pressure sensor and method of use. Background technique [0002] Pressure treatment is a priority intervention for preventing and treatment of venous diseases and lymphatic vessels, is an essential treatment, such as deep vein thrombosis in clinical treatment, hard fat dermatitis, lymphedema and other diseases, as well as other indications, including the prevention of thromboembolism, prevention or permanent swelling of the burn scar soften during pregnancy. Elastic bandage has a certain flexibility, of tension it produces is to rely on the operator during use generated during the degree of leveling. Operator because there are individual differences, the operation when the dressing different way, the pressure generated is not the same. Pressure is too small, no effect, too much pressure may hinder normal limb blood flow whi...

AI Technical Summary

Problems solved by technology

Too little pressure will have no effect, and too much pressure may hinder the normal blood flow of the limbs, which will weaken the treatment effect or even aggravate the condition

In addition, the elastic force of the existing elastic bandage decreases after repeated use. According to the pressure indicator mark on its surface, the actual pressure generated will decrease, and it is difficult to achieve the actual required pressure.

At present, the pressure under the bandage is calculated according to the regular cylinder according to the formula of Laplace's law, but the lower limbs of the human body are irregular bodies, and the bony protrusions and soft tissue textures of various parts are different, which obviously affect the elastic bandage on the local parts of the lower limbs of the human body. resulting final pressure

The actual pressure produced by the elastic bandage is different at each point after the lower limbs of the human body are circled for a week. The traditional pressure sensor obtains the pressure of a local point below it, which does not reflect the actual pressure of the bandage on the circle.
