Description

cardiopulmonary compression device

technical field

The present invention relates to a cardiopulmonary compression device.

Background technique

According to statistics, more than 350,000 people in the United States lose heart function due to "sudden cardiac arrest" (Sudden Cardiac Arrest, SCA) every year, leading to death, and the mortality rate is as high as 95%. According to the American Heart Association (AHA), approximately 9 million people in the United States currently learn CPR each year. The goal of the American Heart Association is to more than double this figure to 20 million people per year within the next five years. This shows the importance of cardiopulmonary resuscitation.

Cardio-Pulmonary Resuscitation (CPR), which means the combination of artificial respiration and artificial chest massage to maintain respiratory function and heartbeat. Because after 4-6 minutes of brain hypoxia, brain cells begin to be damaged; hypoxia for more than 6 minutes can cause irreversible damage. The purpose of CPR is to enable the blood to carry oxygen to the brain to maintain life. CPR can achieve a certain degree of first aid effect in sudden or unexpected accidents caused by respiratory and cardiac arrest, such as: heart attack, drowning, electric shock, car accident, carbon monoxide poisoning, etc.

Even so, manual CPR, even when done correctly, does not always provide a normal flow of blood to the brain or heart. In addition, inconsistent compression, fatigue, and when the rescuer rotates or moves the patient during CPR can lead to less effective CPR. Therefore, it is the focus of the industry to develop automatic cardiopulmonary compression devices to overcome the limitations of manual CPR, and to provide wide, uniform and consistent compression.

In the prior art, as Michigan Instruments, Inc applied for a U.S. patent in 1999, the patent name and number were High impulse cardiopulmonary resuscitator, US. Pat. No. 6,171,267, as shown in Figure 1. The above-mentioned patent proposes an automatic device for performing cardiopulmonary resuscitation on patients by means of reciprocating action of a piston driven by air pressure. The device mainly presses the patient's sternum partially through the cushion at the front end of the piston, increasing the internal pressure of the chest cavity and allowing the Blood circulation in the body prevents brain death due to lack of oxygen in the patient's brain. The structure of the device 1 mainly includes a base plate 11, a supporting pillar 12, and a cantilever air chamber 13. The air chamber 13 contains a gas flow regulator, a control air valve and a sequence control circuit, and its power is transmitted through the tube. The circuit 14 is connected to an air pressure source (not shown in the figure), and the control circuit can control the compression depth and frequency of the piston 15. When using this device, the height of the cantilever air chamber 13 must be adjusted according to the size of the patient, and the supporting pillar 12 and the bottom plate 11 must be properly fixed. Therefore, it is not suitable for outdoor use in operation and is often placed on a hospital bed. Besides; in addition, because the chest massage method is similar to that of manual force application, there is also the risk of chest rib contusion and fracture during compression, and it cannot provide a relatively uniformly distributed large-area pressure.

In addition, a CPR assisting device 2 disclosed in US Pat. No. 6,398,745 obtained by Revivant Corporation is shown in FIG. 2A and FIG. 2B . The above-mentioned patent proposes an automatic device for performing cardiopulmonary resuscitation on the patient by using a motor to drive a rolling bar to drive the belt around the patient's chest to do a reciprocating unwinding action. A large area of compression increases the pressure difference in the patient's chest cavity and provides more blood flow to internal organs. The device 2 mainly includes a load base 20, a motor drive mechanism 21, a rolling bar 22 driven by the motor, a belt 23 for compression, and a motor control circuit module 24. The motor control circuit module 24 can control the direction of motor rotation, rotation frequency, rotation angle and the actuation of the clutch and brake in the motor drive mechanism 21, and the effect of chest massage can be produced by winding the belt 23 with the rolling bar 22, and because of its compression mode Applying pressure to a large area can reduce injury inside the chest cavity and improve the efficiency of compression. Although this type of cardiopulmonary resuscitation device is a non-invasive emergency medical device, the relevant electrical safety regulations for the electrical control unit used in it are still quite strict, the motor winding mechanism is complicated and easily causes the risk of failure, and the manufacturing cost is relatively increased, etc. class questions.

Based on the above, there is an urgent need for a cardiopulmonary compression device to solve the problems in the prior art.
