Problems solved by technology

[0003] However, since the joint between the blood collection tube and the cap is entirely based on friction, the cap often breaks away from the blood collection tube in advance during the centrifugation process, causing blood to splash.

Embodiment Construction

[0010] Such as figure 1 As shown, the centrifuge filter disc of the present invention is used in conjunction with the centrifuge sleeve pipe, and the filter hole 1 corresponding to the centrifuge sleeve pipe is arranged at the bottom of the dish 3, and the diameter of the filter hole 1 should be greater than the diameter of the blood collection tube 4 and smaller than the blood collection tube tube The diameter of the cap is 5, and the disc edge 2 rides on the outer periphery of the centrifuge casing.

[0011] Such as Figure 4 As shown, the outer side of the blood collection tube 4 of the invention has a protruding rib 6, and the inside of the blood collection tube cap 5 has a groove 7, and the protruding rib 6 and the groove 7 are matched.

[0012] The depth of the pan bottom 3 is consistent with the height of the cap 4 of the blood collection tube.

[0013] When the centrifuge is working, the filter hole blocks the tube cap of the blood collection tube. When the rotation ...

Abstract

The invention relates to a filter disc of a centrifugal machine. The filter disc of the centrifugal machine is matched with a bushing of the centrifugal machine in use, a filter hole corresponding tothe bushing of the centrifugal machine is formed in a chassis, the diameter of the filter hole is greater than that of a blood sampling tube but smaller than that of the cap of the blood sampling tube, and the disc edge is overlapped to the periphery of the bushing of the centrifugal machine. The filter disc of the centrifugal machine provided by the invention is characterized in that a protrudingrib is arranged on the outer side of the blood sampling tube, a groove is formed in the inner side of the cap of the blood sampling tube, and the protruding rib is matched with the groove. As a result of mutual action of the protruding rib and the groove, the automatic uncapping opportunity is more accurate, and blood splashing as the cap is separated from the blood sampling tube in advance is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a matching device of a centrifuge and a centrifuge filter disc. Background technique [0002] At present, negative pressure blood collection tubes are widely used in the medical field to collect blood from patients, mainly using the negative pressure sealed in the blood collection tubes to extract blood from patients. The sealing device is generally a cap, and the centrifugal sleeve of the centrifuge is now mostly made of stainless steel. It has the advantages of high strength, heat resistance and no deformation, but there is no cap. The negative pressure blood collection tube is sealed by the cap. After the blood is centrifuged in the centrifuge, the blood collection tube is taken out. The operator needs to remove the caps one by one, and the workload of removing the cap is very heavy. Large, the operator pulls out the tube cap for a long time, which is easy to cause physical an...
