Foot-operated CPR compression device

Abstract

The invention discloses a foot step type cardio-pulmonary resuscitation pressing device, and relates to the technical field of cardio-pulmonary resuscitation devices. The foot step type cardio-pulmonary resuscitation pressing device comprises a C-shaped supporting plate, a pneumatic piston mechanism and a foot step type air inflation mechanism; a piston push rod in sliding and sealing fit with the inner wall of a piston cylinder is arranged in the piston cylinder; an electromagnetic switch valve as well as an air pressure sensor used for measuring air pressure of a piston cavity is mounted on the top surface of the piston cylinder; the air pressure sensor is connected with the input end of a microprocessor; the output end of the microprocessor is connected with the electromagnetic switch valve; a dual start-up air inflation device comprises a baseplate and two air inflation cylinders mounted on the baseplate in parallel; the output ends of the two air inflation cylinders are both connected with branch air guide pipes; the tail ends of the two branch air guide pipes are both connected with a main air guide pipe; the other end of the main air guide pipe is communicated with the piston cavity of the piston cylinder; one-way valves for guiding the two branch air guide pipes to the main air guide pipe are mounted on the two branch air guide pipes respectively. Through the adoption of the soft structure, the foot step type cardio-pulmonary resuscitation pressing device can sleeve lower limbs, the massage areas are large, and influence on normal walking and work can be avoided.

Description

technical field [0001] The invention relates to the technical field of cardiopulmonary resuscitation devices. Background technique [0002] Cardiac Arrest (Cardiac Arrest, CA) refers to the sudden cessation of beating of the heart caused by various reasons, which leads to the sudden cessation of effective cardiac pump function and effective circulation, causing serious loss of tissue cells throughout the body. Blood, hypoxia and metabolic disorders, if not rescued in time, they will lose their lives immediately. Sudden cardiac arrest is different from cardiac arrest in the terminal stage of any chronic disease. If correct and effective resuscitation measures are taken in time, the patient may be saved and recovered. [0003] Once cardiac arrest occurs, if immediate rescue and resuscitation is not obtained, it will cause irreversible damage to the patient's brain and other vital organs and tissues in 4 to 6 minutes. Therefore, cardiopulmonary resuscitation (CPR) after cardia...

Problems solved by technology

Especially when the patient is lying flat on the hospital bed, since the bed body has a certain height, it is not easy to apply an appropriate pressing force to the patient.
