Voice prompt manual cardiopulmonary resuscitator

Abstract

The invention relates to a medical appliance, in particular to a voice prompt manual cardiopulmonary resuscitator used in first aid and rescue of cardiac arrest cases. The major technology adopts manual operation that: a user can hold a handle by hand to press down an adjustable pressing rod at a frequency of 100times / minute; thus, a pressing column is driven to move up and down 4 to 5cm, and a pressing rubber head presses the lower part of a breastbone to move up and down 4 to 5cm in the same way, thereby reaching the goal of cardiac compression; moreover, when moving up and down, the pressing column pulls an air-compressing rack and an air sac cover to move downwards periodically at a frequency of 10times / minute; and a ventilation change-over switch at the upper end of the air-compressing rack can be adjusted to ensure that 300 or 600ml air in an air sac enters the respiratory tract of a patient through a chassis air sac blow vent, an air division check valve, and the like; thus, an inspiratory process of the patient is completed. The voice prompt manual cardiopulmonary resuscitator has the advantages of simple structure, easy manufacturing, low price and no restriction on using condition.

Description

technical field [0001] The invention relates to a medical device, more specifically, it is a manual cardiopulmonary resuscitation machine for emergency rescue of cardiac arrest cases with voice prompts. Background technique [0002] At present, the vast majority of medical institutions in my country, especially small and medium-sized hospitals at the grassroots level, use manual CPR to rescue cardiac arrest cases. Manual CPR is almost the only way for cardiac arrest before and outside the hospital. Factors such as difficulty in controlling the rhythm and frequency, and difficulty in maintaining the amplitude and frequency lead to a low success rate of rescue, especially when the operation is performed by a single person, because heart compressions are often forced to be interrupted, and the operator is prone to fatigue and other factors, resulting in a lower success rate of rescue. Cross-infection between doctors and patients is prone to occur. A few hospitals use cardiopulmon...

Problems solved by technology

[0002] At present, the vast majority of medical institutions in my country, especially small and medium-sized hospitals at the grassroots level, use manual CPR to rescue cardiac arrest cases. Manual CPR is almost the only way for cardiac arrest before and outside the hospital. Factors such as difficulty in controlling the rhythm and frequency, and difficulty in maintaining the amplitude and frequency lead to a low success rate of rescue, especially when the operation is performed by a single person, because heart compressions are often forced to be interrupted, and the operator is prone to fatigue and other factors, resulting in a lower success rate of rescue. Cross-infection between doctors and patients is prone to occur. A few hospitals use cardiopulmonary resuscitation machines to rescue cases of cardiac arrest. However, there are all kinds of cardiopulmonary resuscitation machines that rely on power such as electricity (electric) and gas (pneumatic). It can only be used in hospitals, and there are problems such as inconvenient use, complicated operation, and high price, which obviously restrict the popularization of cardiopulmonary resuscitation machines

At present, there is no voice prompt manual cardiopulmonary resuscitation machine for sale in the medical device market
