AI Technical Summary

Technical Problem

Existing orthopedic restraint devices are prone to excessive compression or excessive gaps when manually adjusting the pressure, which can affect blood circulation and fracture stability, increase the risk of micromovement, and cannot adapt to the limb remodeling changes during the callus growth process.

Method used

It employs an automatic pressure limiter, including a pressure sensor, airbag, controller, and solenoid valve. By detecting and adjusting the pressure inside the airbag in real time, and in conjunction with a removable breathable liner and angle adjustment mechanism, it dynamically adapts to changes in limb circumference during callus growth, providing stable support and comfortable fixation.

Benefits of technology

It provides continuous and stable support to the fracture site, avoids excessive pressure or loosening, ensures smooth blood circulation in the limb, and improves patient comfort and rehabilitation efficiency.

Abstract

The invention relates to the technical field of orthopedic instruments, in particular to a constraint nursing device for the orthopedics department. The constraint nursing device for the orthopedics department comprises a first chuck, a second chuck and a connecting rod; a connecting rod is fixedly connected to the front end of the first chuck, a second chuck is rotatably connected to the outer side of the connecting rod and located in front of the first chuck, a first restraining mechanism is arranged on the top of the first chuck, a second restraining mechanism is arranged on the left side of the second chuck, and automatic pressure limiters are detachably connected to the first restraining mechanism and the second restraining mechanism. A fixing band and a lining on a U-shaped plate corresponding to a fracture part are replaced by a mounting ring with a built-in air bag, the internal pressure of the air bag is detected in real time through a pressure sensor, a controller automatically triggers an air pump and an electromagnetic valve to inflate and deflate, and the shaping change of the limb circumference along with swelling fading in the callus growth process is dynamically adapted.
