Problems solved by technology

[0003] For the inflatable counterpulsation device, it has the following obvious and unchangeable defects: 1. The response of the high-pressure inflatable counterpulsation action is not timely, and the counterpulsation pressure cannot be automatically controlled and adjusted automatically; 2. The best one cannot be automatically adjusted according to the effect of the counterpulsation Counterpulsation volume; 3. Different counterpulsation modes cannot be used according to the specific conditions of different patients; 4. Large volume, many equipment, and loud noise
Due to the inability to fully meet the high requirements of medicine for external counterpulsation, it is difficult to popularize external counterpulsation, and it is even more difficult to enter the family for health care purposes.
[0004] As for the servo hydraulic counterpulsation device, it also has obvious unchangeable defects: the hydraulic system has high sealing requirements, and once the leakage cannot be remedied, the parts must be replaced; it is inconvenient for the patient to use

example 1

[0027] Example one ( figure 2 ):

[0028] Respectively set ECG sensor 5a or pulse sensor 5b, blood flow sensor 7, and three groups of pressure sensors 6 (a.b.c) and connect to expandable industrial control PC (PLC) 8, design corresponding control program, according to ECG (or pulse ) signal sends an action command to the servo motor controller 10 at the best time, and after receiving the action command, the servo motor controller 10 sends an independent direction and speed command or a stop command to the three groups of servo motors 1 (a.b.c). The servo motor 1 (a.b.c) transmits the rotational energy to the three sets of ball screws 2 (a.b.c) respectively according to the commanded direction and speed, and the three sets of ball screws 2 (a.b.c) convert the rotational energy of the servo motor 1 (a.b.c) into different Direction and speed of the linear action force respectively drive the three sets of closed pressure deformation transmission devices 3 (a.b.c) for compression...

example 2

[0029] Instance two ( image 3 );

[0030] Instead of using three sets of closed air pressure systems with servo control and action, this example uses a set of closed air pressure system with servo control and action to counterpulse the calf, thigh, and buttock air bags. The servo motor 1, the servo motor controller 10 and the ball screw 2 form a single precise action system, and the calf air bag C 1(2) and thigh air pack B 1(2) , thigh air bag B 1(2) And buttocks air bag A 1(2) One side is connected with pipeline 14 respectively, and the closed pressure deformation transmission device 3 is connected with the calf air pressure bag C by pipeline 4 1(2) , calf air bag C 1(2) Attach Thigh Compression Pack B 1(2) , thigh air pack B 1(2) Then connect the hip air bag A 1(2) . The single precise action system 1, 2 drives the closed pressure deformation transmission device 3, and sequentially adjusts the calf air bag C 1(2)) , thigh air bag B 1(2) And buttocks air bag A 1(...

example 3

[0031] Example three ( Figure 4 ):

[0032] A simple counterpulsation system can only compress the lower limbs and accelerate the venous return of the lower limbs to the heart, and its effect is limited. Thus, in( figure 2) on the basis of adding a set of servo-closed air pressure beating system D in the heart area. Its movement is opposite to that of the lower limb counterpulsation in terms of timing. When the heart contracts, that is, when the lower limb counterpulsation releases pressure, the heart area servo-closed air pressure pulsation system performs a positive beat, which strengthens the heart's ability to pump blood outward and enhances the blood supply capacity of the arteries. , so that the blood supply of each important organ is directly strengthened, and it also has the function of directly flushing the arteries, which makes up for the helplessness of the existing external counterpulsation on the arteries. Together with the lower limb counterpulsation, the ne...

Abstract

The invention discloses a closed pneumatic type in-vitro positive pulsation and counter pulsation device for servo control and action. The device is formed by adding an in-vitro positive pulsation system of a chest cardiac area into an in-vitro counter pulsation system; a servo motor is provided with a ball screw to form a power system; a closed pressure deformation transmission device is used for transmitting pressure to a human body through the ball screw and pneumatic pressure packets to realize positive pulsation and counter pulsation; and relevant information is acquired, and the positive pulsation and the counter pulsation are precisely controlled through a control system. Compared with the prior art, the closed pneumatic type in-vitro positive pulsation and counter pulsation devicecomprises the following outstanding characteristics that: a cardiac positive pulsation system is added to completely realize the positive pulsation and the counter pulsation; a closed pneumatic system is simple and practical; closed pneumatic pressure is combined with a servo system to simply realize precision and controllability; the closed loop control of the positive pulsation and the counter pulsation is realized by blood flow detection; the pressure control of pneumatic packets is realized by pressure detection so as to control the amount of the positive pulsation and the counter pulsation; and a set of servo pneumatic system is used for the counter pulsation to three groups of pneumatic pressure packets, electrocardial detection is replaced by pulse detection, and the device is convenient to use and has a simple structure.

Description

technical field [0001] The invention relates to an external counterpulsation device, which does not use the current inflatable counterpulsation, nor uses liquid as the energy transfer mode, but uses the servo control principle to drive the sealed gas to carry out Extracorporeal positive and counterpulsation devices for pressure transmission. Background technique [0002] At present, most of the external counterpulsation devices at home and abroad use compressed air for inflatable counterpulsation. For example, the external counterpulsation devices disclosed in Chinese patents 91103893.1, 02225981.3, and 03210740.4 are all counterpulsation devices that are inflated by compressed air, but except for Chinese patent ZL200910107880.1, a servo system is used to push a closed hydraulic system to counterpulsation , and similar to the present invention. The present invention uses the servo system to promote the closed air pressure system to come forward and reverse, and there are d...
