Blood centrifugal separation equipment

Abstract

The invention discloses blood centrifugal separation equipment which comprises an outer cylinder, an inner cylinder, a liquid guide pipe, a first tissue fluid box and a second tissue fluid box, the inner cylinder is rotationally connected to the interior of the outer cylinder, and the liquid guide pipe is located on the side wall of the outer cylinder and the side wall of the inner cylinder; the side wall of the end, located outside the outer cylinder, of the liquid guide pipe is connected with an adjusting box through a liquid outlet pipe and is in fluid communication with the adjusting box, and the adjusting box is connected with the first interstitial fluid box and the second interstitial fluid box through a first liquid inlet pipe and a second liquid inlet pipe and is in fluid communication with the first interstitial fluid box and the second interstitial fluid box; by means of the device, a large amount of blood can be centrifugally layered at a time, tissue fluid of different layers flows out through the liquid guide pipe, the tissue fluid needed by the different layers can be extracted only through one liquid guide pipe, the tissue fluid can be rapidly extracted, the device can conduct centrifugal treatment on the blood of different specifications and different masses, and the operation is easy and convenient. The specification and the size of the inner cylinder do not need to be changed, and the blood extraction efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of blood separation. Specifically, it is a blood centrifugal separation device. Background technique [0002] Blood centrifugation is a method of separating blood components by gravity centrifugation. After blood separation, it is stratified into plasma, white blood cells, platelets and red blood cells from top to bottom. At present, when the stratified tissue fluid is extracted The method of manual extraction is often used. Medical staff first extract tissue fluid from top to bottom, and store different layers of tissue fluid through different vessels. In such cases, it is necessary to rely on medical staff to identify the amount extracted, which is prone to interstitial fluid mixing. Therefore, the manual collection method not only wastes a lot of manpower, but also leads to incomplete collection of tissue fluid. SUMMARY OF THE INVENTION [0003] Therefore, the technical problem to be solved by...

[0002] Blood centrifugation is a way to separate blood components by gravity centrifugation. After blood separation, it is stratified into plasma, white blood cells, platelets and red blood cells from top to bottom. At present, when extracting the stratified tissue fluid , the method of manual extraction is often adopted. The medical staff first extracts the tissue fluid from top to bottom, and stores different layers of tissue fluid in different containers. Phenomenon, so the manual collection method not only wastes a lot of manpower, but also leads to incomplete collection of interstitial fluid
