arm flexion restriction device

Abstract

The invention provides an arm bending limiting device. The arm bending limiting device comprises a first sleeve, a second sleeve, a coil, a control unit, a coil drive circuit, a capacitor and a capacitance detection circuit, wherein the first sleeve comprises an outer periphery wall and an inner periphery wall, and the outer periphery wall and the inner periphery wall are spaced at a preset distance, so that an accommodation space is formed; the second sleeve is inserted into the accommodation space of the first sleeve, the second end of the second sleeve extends to exceed the second end of the first sleeve, and a magnet is formed on the second sleeve; a spring is arranged on the bottom of the accommodation space; the first end of the spring is connected with the bottom of the accommodation space, and the second end of the spring is connected with the first end of the second sleeve; the coil is arranged at the first end of the first sleeve; the outer periphery wall of the first sleeve forms a first electrode plate of the capacitor, the inner periphery wall of the first sleeve forms a second electrode plate of the capacitor, and the second sleeve is configured to be a dielectric medium capable of being inserted between the first electrode plate and the second electrode plate of the capacitor.

Description

technical field [0001] The invention relates to a medical device, in particular to an arm bending limiting device. Background technique [0002] For bedridden patients undergoing intubation, a common problem encountered during nursing is that the patient is agitated and the intubation inserted in the head is pulled out. This creates difficulties in preventing extubation since agitation is difficult to predict in advance. The current conventional practice is that for patients with possible restlessness, their upper limbs are restrained on the hospital bed by restraint belts. Although this method can effectively avoid the occurrence of extubation phenomenon, the patient's upper limbs are tied to the hospital bed from beginning to end, which is psychologically unacceptable to both the patient himself and his family members. Contents of the invention [0003] In view of the above problems, the present invention aims to propose an arm bending limiting device, which can limit ...
