Automatic medical constant-force small splint

Abstract

An automatic medical small splint with constant force features that an air bag is connected with air filling unit, air releasing unit and air pressure acquiring module via air tubes, the frequency output of said air pressure acquiring module is connected to the counter input of a microcontroller, and said microcontroller has the outputs connected respectively to air filling and releasing units and LCD module and the input connected to keyboard.

Description

technical field [0001] The invention belongs to the technical field of medical instruments. Background technique [0002] External fixation with small splints is a common treatment for limb fractures, especially upper limb fractures. The application of small splints must correctly grasp the principles and methods of use, the pressure pad should be placed properly, and the cable ties should not be too loose or too tight. If it is too loose, the fixation will not be firm, and the fracture will easily shift again and affect the healing. If it is too tight, it will easily cause local skin pressure sores, and in severe cases, it will cause ischemic muscle contracture of the limbs, and even gangrene of the limbs. Therefore, after the small splint is fixed, the tightness of the cable tie should be checked frequently, and the splint cable tie and pressure pad should be adjusted in time. The adjustment of the tightness of the splint tie depends entirely on the doctor's experience a...

Problems solved by technology

The adjustment of the tightness of the splint tie depends entirely on the doctor's experience and feel. This subjective impression lacks scientific basis and normative standards. It is completely based on the doctor's experience and operating methods, which is very easy to cause mistakes.

[0003] At present, "a small fracture self-control splint" invented by Luo Ziping in China, which constitutes a pressure switch through the final shaft, ring contacts, springs, etc., designs two sets of pressure switches to control the alarm, and the alarm device emits an alarm sound, replacing the hand feeling with measurement, but Its detection sensitivity is not as good as that of semiconductor electrostatic capacitive pressure sensors, and there is no accurate measurement display; Zhong Yanguan and Zhong Yuquan invented "a practical small splint for fractures". The scale with scale is just to make it easy to adjust the tightness of the cable tie, but it has no measurement standard and no alarm function; Zhao Jiyin invented the "automatic monitoring of small splints", which has high measurement accuracy and has a display function, but has no automatic control function. , adjust the pressure value manually
