Description

Centrifugal boosting type cardio-pulmonary resuscitation auxiliary garment

Technical Field

The invention relates to the technical field of medical auxiliary appliances, in particular to a centrifugal boosting type cardio-pulmonary resuscitation auxiliary garment.

Background

Cardiopulmonary resuscitation is important first aid means, it uses both hands to press patient's chest lung to need medical personnel, and then press through the thorax, kick-back realizes assisting the heart and beat, thereby realize cardiopulmonary resuscitation, but because the pressure of pressing the in-process comes from medical personnel's self gravity mostly, this just leads to the person of rescue who part weight is lighter to press the in-process and can't reach qualified depth of pressing, thereby lead to resuscitating the success rate low, consequently need use cardiopulmonary resuscitation auxiliary clothes to increase person of rescue's pressing force degree.

Novel cardiopulmonary resuscitation auxiliary clothes is used in medical treatment like publication No. CN208480644U, it is provided with the placing bag at the front and the back of auxiliary clothes body, and the lead rubber piece has been placed to the inside of placing bag, and the weight of lead rubber piece reduces in proper order to the bottom of auxiliary clothes body from the top of auxiliary clothes body, the total weight of lead rubber piece does not exceed three kilograms simultaneously, can increase the weight of operator's upper part of the body like this, improve cardiopulmonary resuscitation's rescue success rate, can prolong the time that single high quality chest was pressed simultaneously, also can improve the rescue success rate, but it still has some not enoughly in the use, for example:

1. its mode that increases the person of suing and labouring weight only relies on the weight of plumbous rubber piece to realize, leads to needing the plumbous rubber piece of sufficient volume just can increase the whole quality of supplementary clothes, leads to the whole quality of supplementary clothes great, it carries out daily carrying not convenient for, needs the arm-lifting after the person of suing and labouring single presses simultaneously, ensures the resilience of patient thorax, but fixed plumbous rubber piece quality has increased the arm-lifting degree of difficulty of the person of suing and labouring.

2. When the person of suing and labouring presses, because its arm needs be the straight line and puts, lead to arm department atress great, but current cardiopulmonary resuscitation assists the clothes and lacks the auxiliary stay structure to the arm for press the in-process, the arm appears bending easily, the phenomenon of unloading takes place, thereby influences normal rescue, has certain use defect.

We have therefore proposed a centrifugally-assisted cardiopulmonary resuscitation aid garment that addresses the problems set forth above.
