Problems solved by technology

[0004] The defect of the method of one-way centrifugal separation of blood components: because the separation of blood components is completed in the process of blood collection
For example, in the separation method of Fewtlcs-3000plus, the centrifuge container is far away from the centrifuge shaft. During the centrifugation process, the natural pressure inside the centrifuge container cannot be used to press the corresponding blood components to the outside of the centrifuge container.
HAEMONETIL is a broken junction, unable to extend the blood extraction tube to the red blood cell layer

Abstract

The invention relates to a segregation device and method of multidirectional continual blood component, which comprises the following steps: gathering blood by gathering needle (10); pushing the blood to the centrifugal container (12, 30) through the pipe route; setting the external blood flow process pipe system in the multidirectional centrifugal rotary device in connection with blood flow path pipe (6) by several control pumps (1); setting the centrifugal container in the rotational hemisphere (16) of centrifugal rotary device. The driving shaft (33) between rotational hemisphere and centrifugal rotary device is fixed to rotate with rotational hemisphere along its own orbital trace. The device transmits the signal from color comparator sensor (4) to corresponding control system after multidirectional centrifugal separating, which shortens the gathering blood time to improve the gathering rate of blood component and is applied in the clinical blood pathological component separation or improves the clinical curative effect in displacement therapy.

Description

Technical field: [0001] The invention relates to the technical field of blood circulation system removal, and relates to a multidirectional centrifugal continuous blood component separation device and method. Background technique: [0002] In the process of medical and medical activities, when pathological blood components appear in people's blood, clinically for the removal or replacement of blood pathological components, in the process of blood collection, the blood is subjected to gravity centrifugation to separate various blood components. It is the purpose of extracting and collecting a single or certain blood components in the blood in a short period of time during the process of extracorporeal circulation, extracting and collecting blood components from healthy people, or removing blood components from patients. A technology that spread rapidly. [0003] At present, there are many kinds of blood component separation technologies for clinical application, such as the ...
