technical field

The utility model relates to a blood centrifugal bowl, in particular to a centrifugal bowl with a collection part, which can be made into a small blood centrifugal bowl and has a larger main centrifugal part, which can increase the blood volume inside and has better separation of blood components.

Background technique

Existing blood centrifugation bowls are usually used to separate various components in blood, and there are quite a lot of forms. However, in the prior art, blood centrifugation bowls are all made into large blood centrifugation bowls, and blood centrifugation can only separate blood centrifugation. High-concentration platelet plasma and platelet-poor plasma cannot be directly separated from plasma and high-concentration platelet plasma, because the boundary between the two is less obvious. Moreover, the structure of the blood centrifuge bowl is simple, usually with a smooth shell and core, which is easy to separate Turbulent flow is generated during the centrifugation process, and blood components cannot be separated accurately.

If you want to directly separate high-concentration platelet plasma and platelet-poor plasma, you can usually only use a traditional centrifuge to store the blood in a centrifuge tube. After the centrifugation is completed, use the operator to insert the syringe into the centrifuge tube for extraction. The collection method is manual. Collection, red blood cells are more likely to be extracted during the extraction process, and high-concentration platelet plasma and platelet-poor plasma cannot be collected in large quantities.

In addition, when the existing blood centrifuge bowl is used with an optical sensing device, blood components cannot be separated accurately. Because of its large volume, it requires a large amount of blood samples and cannot completely separate blood components.
