Problems solved by technology

[0003] However, the utilization rate of the silk membrane structure in the current membrane oxygenator is not high, mainly because the blood diversion and diffusion efficiency is not good, 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 membrane type oxygenator which comprises a lower cover, an oxygenation portion and an upper cover. The lower cover is provided with an air outlet tube, the oxygenation portion is arranged in the lower cover and comprises a mandrel structure, an oxygenation housing and an oxygenating silk film structure, the oxygenation housing is provided with a blood outlet tube, and the blood outlet tube is close to the lower cover. The upper cover is arranged on the oxygenation portion and is provided with an eddy structure, a blood inlet structure and an oxygen inlet tube, and the eddy structure corresponds to the mandrel structure. The mandrel structure comprises a mandrel body and an annular guide plate, the mandrel body is provided with a first end and a second end, a blood channel is formed between the first end and the eddy structure, and the mandrel body is sleeved with the annular guide plate. The mandrel structure of the membrane type oxygenator is provided with the annular guide plate, the annular guide plate guides blood diffusion, the contact area and the diffusion area of blood and the silk film structure are increased, and the utilization rate of the silk film structure is improved.

Description

technical field [0001] The invention relates to the technical field of medical device products, in particular to a 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 the same time provides the d...
