Membrane oxygenator

Abstract

The invention discloses a membrane oxygenator. The membrane oxygenator comprises a blood storage device and an oxygenator body. A connecting pipe is arranged on the lower portion of the blood storage device in a protruding mode, the tail end of the connecting pipe is connected with a connecting shaft which is connected with a rotary table in a clamped mode, the rotary table is connected with a blood inlet pipe in a clamped mode and communicated with the connecting shaft, and the tail end of the blood inlet pipe is connected with the oxygenator body; the oxygenator body comprises an oxygenation chamber and a blood discharge chamber, the oxygenation chamber is communicated with the blood discharge chamber in an integrated mode, the oxygenation chamber and the blood discharge chamber are in an inverted-V-shaped structure, and a blood discharge pipe is arranged on one side of the lower end portion of the blood discharge chamber in a protruding mode. Due to the facts that the connecting shaft is arranged below the blood storage device and the blood inlet pipe is driven by the rotary table on the connecting shaft to rotate, the oxygenator can rotate back and forth. When the membrane oxygenator is used, blood is oxygenated through the oxygenation chamber so that an operation can be performed. After the operation, the rotary table rotates so that blood left in the oxygenation chamber can flow into the blood discharge chamber freely, and the blood is recycled through flow guide of the blood discharge pipe. The membrane oxygenator is simple in structure, convenient to use and capable of ensuring that the blood is stably recycled.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a membrane oxygenator. Background technique [0002] As we all know, the membrane oxygenator is a medical device that stops the heart and replaces the lungs. 2 and CO 2 The function of content is the necessary 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. Its principle is to lead the venous blood in the body out of the body, and then perform internal oxygenation after passing through the temperature-changing system of the membrane oxygenator. 2 and CO 2 Exchange into arterial blood, and then reinfuse the patient's arterial system, maintain the supply of oxygenated blood to human organs and tissues, temporarily replace the role of the lungs during the operation, and provide doctors with a quiet, bloodless, and clear operating environment for easy i...

Problems solved by technology

[0004] The blood in the traditional oxygenation chamber still has a small amount of residual blood after surgical treatment, while the oxygenation chamber and the blood storage tank are connected in a fixed way. At this time, if the blood needs to be reused, the entire membrane type The oxygenator device is detached from the bracket and poured into other containers for reuse. The operation is not only cumbersome, but also increases the damage to the blood during the transfer process, which in turn affects the quality of the subsequent blood supply.
