Description

Coil structure applied to mixed liquid continuous centrifugal separation system

Technical field

Whether it is scientific research or medical clinical practice or industrial production, and more, it is necessary to continuously centrifuge the mixed liquid, such as separating blood from whole blood into a single cell component. Blood collection agencies and research institutes usually use centrifugation to separate individual components from a mixture of multicellular components for clinical treatment, scientific research, or preparation of raw materials. Most commonly, whole blood is separated from red blood cells, granulocytes, monocytes, platelets, and plasma by a centrifugal separation system, or the frozen red blood cells after thawing are washed to separate red blood cells and washing liquid.

The working principle of the centrifugal separation system is: The centrifuge, the infusion pump and the controller device introduce the multi-cell component mixed liquid into the soft bag of the separation drum through the infusion line, and simultaneously rotate the separation drum at a high speed to drive the soft drum of the separation drum in rotation. The liquid and cell particles in the mixed liquid of the multi-cellular component are rotated at high speed. These liquid and cell particle components are subjected to the centrifugal force field, and then various components are subjected to centrifugal sedimentation movement, and according to the respective density or specific gravity or the sedimentation coefficient. The layer, when the equilibrium of the centrifugal sedimentation is reached, the concentrically formed single component layers are formed from the radial circumferential surface to the axial center from the high density to the low enrichment.

In the continuous centrifugal separation system of the mixed liquid, the material and the separated product need to be continuously input and output by centrifugation through a closed hose, and the hose drawn from the separation drum is rotated and wound by the high-speed rotation of the separation drum, the hose The other end is fixed outside the centrifugal separation system. Therefore, one end of the hose is rotated at one end and a coil structure is required to realize unwinding and unwinding of the hose. Due to the existence of this coil structure, a material such as a mixed liquid such as whole blood is introduced into the rotating separation drum, and a separated product such as a liquid single component liquid is withdrawn from the rotating separation drum under centrifugal conditions.

There are mainly patents related to the coil structure applied to blood centrifuge equipment in the prior art. US Patent No. 5,360,542. In this patent, the coil structure mainly comprises a bottom frame, a rotatable top bracket, and a top suspension bracket for hanging the separation drum. A flexible shaft is fixed from the chassis to the two bearings on the side of the top bracket and then extends into the separation. At the bottom of the drum, the end of the flexible shaft is a square head that projects into a square groove at the center axis of the separation drum. The flexible shaft has a hollow structure, and a plurality of conveying hoses are arranged inside, that is, the hose and the flexible shaft are integrated. Based on the above structure, the power rotates the top bracket to drive the flexible shaft to generate the torsional power, and transmits the power to the separation drum to cause the same direction of rotation, and at the same time, the hose that is in the same direction as the flexible shaft is unwound.

The above structure has the following disadvantages: Due to the integrated arrangement of the flexible shaft and the hose, the flexible shaft and the hose become the disposable use materials for blood separation, thereby greatly increasing the use cost of the centrifugal separation, especially the flexible shaft hose. The cost of making the combination is very high. Summary of the invention
