Pneumatic-controlled pneumatic cardiopulmonary resuscitator, pressing-breathing automatic switching system and method thereof

Abstract

The invention discloses a pneumatic-controlled pneumatic cardiopulmonary resuscitator, a pressing-breathing automatic switching system and a method thereof. According to the invention, a gas source enters a left and right pulse-controlled valve through a first pneumatic-controlled valve, and than enters a second pneumatic-controlled valve for controlling the action of pressing heads; the gas source simultaneously enters a first counting valve, such that a pressing frequency is counted; when the pressing frequency reaches a set value, the gas source enters a third pneumatic-controlled valve through the first counting valve for controlling a breathing apparatus to blow; the gas source simultaneously enters a second counting valve, such that a breathing frequency is counted; the gas source simultaneously returns to the first pneumatic-controlled valve to pause the action of the pressing heads; when the breathing frequency reaches a set value, the gas source enters a fourth pneumatic-controlled valve through the second counting valve for triggering the first pneumatic-controlled valve, such that action of the pressing heads is recovered; the gas source simultaneously returns to the third pneumatic-controlled valve to pause the breathing apparatus from blowing. The steps are repeatedly circulated, and pressing and breathing are automatically switched according to preset ratios. Because no electric-controlled element or electronic component is used, the labor intensity of emergency staffs is reduced, resuscitation success rate is improved, and safety and reliability of the cardiopulmonary resuscitator are improved.

Description

technical field [0001] The invention relates to the field of a pure air-controlled pneumatic cardiopulmonary resuscitation machine and a control system for full switching between compression and breathing. More specifically, the improvement relates to an air-controlled pneumatic cardiopulmonary resuscitation machine and a system and method for automatic switching between compression and breathing. Background technique [0002] There are two main control principles of current cardiopulmonary resuscitation equipment: one is the electro-pneumatic type, and the technical part relies on electronic chips to control; the other is the air-controlled pneumatic type. Since high-purity oxygen is often used in first aid, this means that there are limitations in the application of electronic control components; in addition, general cardiopulmonary resuscitation may also cooperate with defibrillation with high voltage, which will also affect Even damage electronic components.

Problems solved by technology

[0004] However, traditional air-controlled pneumatic equipment can only achieve independent compression functions, and does not have a fully automatic compression-breath synchronization function; To achieve a separate continuous pressing mode, you need to stop the control switch to complete 2 breaths when breathing, which increases the labor intensity of the ambulance personnel and prolongs the rescue time; while the air-controlled pneumatic equipment outside China, such as the old Saab 1007, It can only achieve the automatic breathing function of 5:1 compression and breathing, which does not meet the new regulations of the AHA Cardiopulmonary Resuscitation Guidelines 2010 Edition, and the new Saab 1008CCV has changed from air-controlled pneumatic to electro-pneumatic

[0005] Therefore, prior art still needs to improve and develop
