Problems solved by technology

These costs are also unacceptable to domestic patients
[0006] This is the difficult situation faced by domestic cardiovascular physicians: on the one hand, there are a large number of patients who need to be treated; on the other hand, it is difficult for foreign products to enter the domestic market, and there are no mature products available in China.
As a result, in many clinical situations, doctors lack powerful weapons and can only witness patients who could have been cured being swallowed by the disease

Embodiment 1

[0047] see figure 1 Shown is a specific embodiment of a balloon counterpulsation-driven mechanically assisted circulation device with valves described in this application. The mechanically assisted circulation device includes: a drainage pipeline 10, an input valve 20, and a balloon counterpulsation system , a blood storage chamber 60, an output valve 70 and an infusion line 80, wherein,

[0048] The balloon counterpulsation system includes: a control system 40, an alarm system 50 and a balloon 30, the balloon 30 is connected with the control system 40 and the alarm system 50 through a balloon catheter 31, the balloon 30 is filled with a working medium, the working medium is gas or liquid, the volume of the balloon 30 is 0.1ml to 500ml, and the counterpulsation frequency of the balloon 30 is 1 beat / min to 100000 beats / min, so The counterpulsation pressure of the balloon 30 is 1 mmHg to 300 mmHg;

[0049] The balloon 30 is located in the blood storage chamber 60, and the two ...

Embodiment 2

[0066] The application examples of applying the mechanical assisted circulatory device of the present application to the extracorporeal mechanical assisted circulatory device are provided below, see figure 2 .

[0067] exist figure 1 On the basis of the illustrated embodiment, when the input valve 20, the balloon 30, the blood storage chamber 60 and the output valve 70 are placed outside the body, the input end of the drainage circuit 10 is connected to To the vein or right atrium, the output end of the drainage line 10 is connected to the blood storage chamber 60 through the input valve 20, the blood storage chamber 60 is connected to the infusion line 80 through the output valve 70, and the output end of the infusion line 80 is connected to vein or artery. From the drainage line 10 to the infusion line 80, the blood flow direction can be from vein to vein, or from vein to artery, for example, the input end of the drainage line 10 can be connected to jugular vein, femoral ...

Embodiment 3

[0073] The following provides an application example of applying the mechanical assisted circulatory device of the present application to the internal mechanical assisted circulatory device-left ventricular balloon counterpulsation system, see image 3 .

[0074] On the basis of the above-mentioned embodiment 1, when the input valve 20, the balloon 30, the blood storage chamber 60 and the output valve 70 are placed in the body, the input valve 20, the balloon 30 , the blood storage chamber 60 and the output valve 70 are located in the left ventricle or the aorta, the drainage pipeline 10 is located in the left ventricle through the aortic valve orifice, and the infusion pipeline 80 is connected to the aorta, The infusion line 80 is located in the aorta to infuse blood into the aorta.

[0075] In this embodiment, the drainage pipeline 10 enters the left ventricle across the aortic valve, and the other end of the drainage pipeline 10 is connected to the blood storage chamber 60...

Abstract

The invention discloses a balloon counterpulsation driven mechanical auxiliary circulating device with valves. The balloon counterpulsation driven mechanical auxiliary circulating device with the valves comprises drainage pipelines, a feeding valve, a balloon counterpulsation system, a blood storage chamber, a discharging valve and infusion pipelines, wherein the balloon counterpulsation system comprises a control system, an alarm system and a balloon; the balloon is connected with the control system and the alarm system through a balloon catheter; the balloon is positioned in the blood storage chamber; two ends of the balloon catheter are respectively connected to the balloon positioned in the blood storage chamber as well as the control system and the alarm system which are positioned on the outside via the infusion pipelines or the drainage pipelines; and the control system controls counterpulsation frequency of the balloon through the balloon catheter, provides a driving force for the blood storage chamber for discharging blood during counterpulsation of the balloon, and controls blood discharge capacity of the blood storage chamber. When the feeding valve, the balloon, the blood storage chamber and the discharging valve are placed in the outside, an external mechanical auxiliary circulating device is formed; and when the feeding valve, the balloon, the blood storage chamber and the discharging valve are placed in the body of a patient, an internal mechanical auxiliary circulating device is formed.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a mechanically assisted circulation device driven by a valved balloon counterpulsation. Background technique [0002] With the aging of the population, there are more and more heart failure patients, and almost all heart diseases will eventually lead to heart failure. The high cost of heart failure treatment places a heavy burden on society as a whole. Heart failure treatment methods are limited and the effect is not ideal. Especially for patients with advanced heart failure, the effect of drug therapy is very poor, and the effect of heart transplantation is good. However, transplantation faces problems such as severe shortage of donors, immunosuppression after transplantation, and expensive drugs. Therefore, after years of development, transplantation treatment still cannot solve the fundamental problem. . The emergence of Mechanical Circulation Support (MCS...
