Electric control pneumatic cardio-pulmonary resuscitation machine

Abstract

The invention relates to an electric control pneumatic cardio-pulmonary resuscitation machine and belongs to the field of medical machinery. The machine is used for cardio-pulmonary resuscitation emergency treatment for sudden cardiac arrest of a patient. The electric control pneumatic cardio-pulmonary resuscitation machine structurally comprises a rigid fixing press bow and an equal-altitude back plate. The press bow is composed of fixing rods with scale display, movable sliding rails, a press piston cylinder, a resetting spring and a recessed face press head. The press bow is connected with fixed locks on movable sliding rails on two sides of the equal-altitude back plate through the fixing rods on two sides and is capable of moving vertically through the two fixing rods. A chip control circuit board, an electromagnetic valve, a pressure adjusting valve, a stabilizing air storage cylinder and the like are arranged in the equal-altitude back plate. The equal-altitude back plate has certain inclination, so that doctors can conveniently open an air channel of the patient. The machine utilizes the principle that the machine is controlled by chip circuit board program, press and ventilation are accurately controlled by an electromagnetic valve, press depth and ventilation quantity are controlled by a pressure adjusting valve, system pressure can be compensated by a stabilizing air storage cylinder, and continuous pressure output and ventilation can be ensured. The machine is suitable for cardio-pulmonary resuscitation emergency treatment of the patient suffering from pre-hospital cardiac arrest and in-hospital cardiac arrest.

Description

[0001] Technical field: electric control pneumatic cardiopulmonary resuscitation machine, used for cardiopulmonary resuscitation of patients with sudden cardiac arrest, including automatic heart compression and synchronous ventilation functions for patients. The invention belongs to the field of medical equipment. Background technique: [0002] The clinical manifestations of patients with sudden cardiac arrest are sudden cessation of breathing and heartbeat. Cardiac arrest causes blood circulation in the patient's body to stop, and brain cells and other tissues and organs are hypoxic and die. According to statistics, the success rate of emergency resuscitation for patients with sudden cardiac arrest in my country is less than 1%, and the number of deaths due to cardiac arrest without effective cardiopulmonary resuscitation is more than one million every year, and the number of calls to "120" is the most in the entire medical system patients in cardiac arrest. Cardiac arrest pa...

Problems solved by technology

In the process of clinical practice, the problems of concentrated response are as follows. First, structural application: Due to structural defects, most of them are "C"-shaped structural designs, which cannot be used well with emergency stretchers, and the first aid outside the hospital is limited. , is limited to use in hospitals; some compression depths cannot be continuously adjusted and cannot display effective compression depths; second, environmental applications: some are designed with LCD screens and ordinary batteries, and these components will fail in harsh outdoor environments , causing security issues

Third, functional application: in clinical application, there are three main functional problems that commonly occur: first, when compression and ventilation alternate, the compression is not in place, and the rebound is not in place; the second is that breathing must stop when pressing; When breathing, the compression is interrupted; the compression and ventilation functions cannot be completed synchronously; the third is that the compression depth and ventilation volume cannot be continuously adjusted, and it is not suitable for different groups of people.
