Description

Adjustable inflatable restraint strap

Technical Field

The utility model relates to the technical field of medical appliances, in particular to an adjustable inflatable restraint strap.

Background

A restraint strap is a tool used to limit the movement of a patient's body or limbs to prevent the patient from self-injuring or injuring others. In the safety management of delirium, dysphoric patients, restraint bands are widely used, but are both protective and dangerous appliances. Therefore, the restraint strap is used to balance patient safety, avoid additional injuries caused by restraint, and facilitate nursing staff to use the restraint strap.

The restraining strap devices commonly used in hospitals today include cotton pads and restraining straps on both ends of the cotton pads. When the restraint strap is used, the cotton pad is fixed on the wrist part of a patient, the tightness of the cotton pad part of the restraint strap is adjusted, then the double-loop knot of the restraint strap is wound on the wrist for restraint, and the tail end of the restraint strap is fixed on a bed rail or a bed edge. Although doctors can adjust the tightness of the cotton pad part according to individual conditions of patients (a finger is suitable to be put in) so as to avoid over loosening or over tightening, when patients with agitation or abnormal emotion move limbs, the restraint bands of the wrist parts can loosen or slip, and the risk of unplanned tube drawing or bed falling is increased. In addition, each time it is necessary to turn over the patient or adjust the tightness of the restraining band, the double loop of the restraining band and the wrist portion fixed to the bed rail is required to be released, which takes a lot of time. Therefore, there is a need to optimize the current restraint strap to improve its safety and convenience.
