Problems solved by technology

[0003] However, the utilization rate of the silk membrane structure in the current membrane oxygenator is not high, mainly because of the poor efficiency of blood diversion and diffusion, blood is easy to accumulate in a certain place in the membrane oxygenator, and only from the silk membrane One part of the structure flows through, and the blood does not flow through other parts of the silk membrane structure

Abstract

The invention relates to a spiral flow-guide integrated membrane oxygenator comprising a lower cover, an oxygenation portion and an upper cover. The lower cover is provided with an air outlet pipe. The oxygenation portion is arranged to the lower cover and comprises a spindle structure, an oxygenation shell and an oxygenation cortina structure, and the oxygenation shell is provided with a blood outlet pipe close to the lower cover. The upper cover is arranged to the oxygenation portion and is provided with a blood inlet pipe and an oxygen inlet pipe. The spindle structure comprises a spindle body and an annular flow guide plate, the spindle body is provided with a first end and a second end, a blood channel is formed between the first end and the upper cover, the annular flow guide plate sleeves the spindle body and is provided with at least one flow guide through hole, and the flow guide through holes of the annular flow guide plate are distributed in the annular flow guide plate. The spindle structure of the spiral flow-guide integrated membrane oxygenator is provided with the annular flow guide plate, the annular flow guide plate guides blood to diffuse through the flow guide structure with the flow guide through holes, contact area and diffusion area of blood and the cortina structure are increased, and utilization rate of the cortina structure is increased.

Description

technical field [0001] The invention relates to the technical field of medical device products, in particular to a spiral diversion integrated membrane oxygenator. Background technique [0002] Membrane oxygenator is a medical device that stops the heart and replaces the lungs. It has the function of regulating the oxygen and carbon dioxide content in the blood. It is an essential medical equipment for cardiovascular surgery, and it is also necessary for the treatment of acute respiratory diseases and the stage of waiting for lung transplantation. medical equipment. The principle of the membrane oxygenator is to draw the venous blood in the body out of the body, exchange oxygen and carbon dioxide into arterial blood after passing through the membrane oxygenator, and then reinfuse the patient's arterial system to maintain the supply of oxygenated blood to the organs and tissues of the human body. During the operation, it temporarily replaces the function of the lung, and at ...
