Pulse type artificial lung extracorporeal circulation manager

Abstract

The invention discloses a pulse type artificial lung extracorporeal circulation manager. The pulse type artificial lung extracorporeal circulation manager comprises a one-way flowing blood flow storage unit and an electronic compression pump, wherein the blood flow storage unit is made of an elastic material and is used for storing blood subjected to artificial lung oxygenation, the electronic compression pump is controlled by the control unit and compresses the blood flow storage unit through control, so that the blood is rapidly pumped out of the storage unit through the one-way valve, and pulse type blood pulsation is formed. The IABP and the artificial lung are integrated into a whole, meanwhile, an oxygenation effect is generated, the normal physiological state of pulse type blood flow is guaranteed, and the problem that microcirculation perfusion cannot be guaranteed in cardiogenic shock is solved; meanwhile, the number of pipelines of a patient is reduced, the number of circulating supporting instruments used by the patient is reduced, the risk and cost are reduced, and the treatment effect is improved.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a pulse-type extracorporeal circulation manager capable of performing artificial lung and circulatory support at the same time, an artificial heart-lung machine capable of performing gas exchange and heartbeat for circulatory support in place of the lungs, and also relates to a pulse-type extracorporeal circulation manager capable of performing pulse Type blood flow controller for powerful circulatory support. Background technique [0002] In the past ten years, organ replacement and supportive care have been widely used in medicine, among which the most successful and exciting one is the extracorporeal membrane oxygenation (ECMO), which is an extracorporeal cardiopulmonary support device. Especially in severe pneumonia and acute severe heart failure, it has the effect of bringing the dead back to life. In this new coronary pneumonia, artificial lung equipment has made great contribu...

Problems solved by technology

However, the effectiveness of these two methods is limited in severe cardiogenic shock. First, patients with extremely critical conditions basically have no chance of emergency surgery. Effective perfusion pressure, shock that does not improve microcirculation

What's more, the combined use of IABP and artificial lung, due to the different principles, the direction of counterpulsation and blood flow cannot be controlled, and the perfusion pressure cannot be maintained, which may easily lead to decreased cerebral blood flow and abdominal organ ischemia

IABP and artificial lung machinery cannot be matched synchronously, and usually the operating effect is not satisfactory. Once in this situation, there is no more effective method in clinical practice at this stage. We can only wait for the microcirculatory shock to aggravate, which is difficult to reverse, until death

[0006] In addition, both the artificial lung and the auxiliary catheter of IABP need to be placed in the thoracoabdominal aorta, which not only increases ineffective blood circulation, but also affects and restricts each other, making it impossible to achieve the target therapeutic effect

Moreover, many channels and strong support also increase the difficulty of nursing care, and there are huge risks of catheter-related infection, bleeding, and thrombus.
