Embodiment 1

[0064] The cardiopulmonary resuscitation chest automatic compression equipment disclosed in this embodiment includes an automatic compression device and a control system, such as figure 1 As shown, the automatic pressing device includes a motor 9 , a transmission mechanism 8 , and a pressing head 13 . The compression operation is essentially a linear reciprocating motion. In this embodiment, the transmission mechanism 8 is used to convert the motion of the motor 9 into the up and down linear reciprocating motion of the compression head 13, and the compression head moves up and down to realize chest compression.

[0065] At present, there are many structures to realize linear reciprocating motion, such as: crank slider mechanism, rack and pinion, timing belt, ball screw and so on. The ball screw has high transmission efficiency and high precision, and can realize arbitrary waveform pressing at different motor speeds. Because of its small mass inertia, it is especially suitable ...

Embodiment 2

[0078] The difference between this embodiment and Embodiment 1 is that: Figure 6 , 7As shown, the automatic pressing device in this embodiment includes a box body 7 and a position adjustment structure. In this embodiment, the pressing cantilever 4 is connected to the transmission mechanism through a position adjustment mechanism. The motor 9 is installed in the box body 7, and the position adjustment structure is arranged between the transmission mechanism 8 and the pressing cantilever 4; the position adjustment structure includes a vertical rod 2 and a locking mechanism for locking the vertical rod 2 and the pressing cantilever 4 Mechanism, the vertical bar 2 is fixedly connected with the slide block of the linear guide rail, one end of the pressing cantilever 4 is connected with the vertical bar 2, and the other end of the pressing cantilever 4 is connected with the pressing head 13. The pressing cantilever 4 is a horizontal telescopic structure.

[0079] Such as Figure...

Embodiment 3

[0086] The difference between this embodiment and embodiment one or two is: as Figure 9 As shown, in this embodiment, the pressure sensor 3 for detecting the pressing force is installed at the pressing head 13 . The pressure sensor 3 is installed between the compression head 13 and the compression head connecting screw 11. During chest compressions, the pressure sensor 3 detects the pressure exerted by the compression head on the thorax, which is limited by the chest cavity size of the compression object and the size of the compression head. The sensor requires proper size and good accuracy. In addition, in order to improve the compression effect, the compression head 13 should directly act on the thorax, and the pressure sensor 3 is preferably installed between the compression head 13 and the compression head connecting screw 11, so a miniature pressure sensor is used in this embodiment. Miniature pressure sensors are widely used in the field of precision instruments, with ...

Abstract

The invention relates to the technical field of medical equipment, in particular to a cardio-pulmonary resuscitation thoracic automatic pressing device and a pressing self-feedback system. The systemcomprises an automatic pressing device, a physiologic index detecting module and a control system. The automatic pressing device comprises a motor, a transmission mechanism and a pressing head. The transmission mechanism converts motion of the motor into linear reciprocating motion of the pressing head; a motor and physical index detection module and the control system are electrically connected;the control system achieves starting and stopping control of pressing motions and physiological parameter display and can automatically pressing parameters according to current physiological parameters. The pressing parameters include pressing frequency, pressing depth, pressing waveforms, pressing time and dynamics indexes; the pressing waveforms include sine waves, trapezoidal waves and triangular waves. Automatic thoracic pressing operation can be performed, meanwhile, the pressing depth, frequency and pressing mode can be regulated, the pressing parameters can be automatically optimized according to the feedback physiological parameters, and the independent circulation recovery rate can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic chest compression device for cardiopulmonary resuscitation and a compression self-feedback system. Background technique [0002] 1. Cardiopulmonary resuscitation is the most widely used first aid technology in the world. It uses techniques such as chest compressions, artificial respiration, and electrical defibrillation to rescue emergency and critically ill patients who have stopped breathing and cardiac arrest. The importance of high-quality chest compressions as the main aspect of cardiac arrest resuscitation is self-evident. During chest compressions, changes in compression depth, compression frequency, and compression waveform will affect compression effects. [0003] For the chest compression experiment, the domestic Second Affiliated Hospital of Sun Yat-sen University fully electric control animal cardiopulmonary resuscitation device, the AutoPulse ...
