Description

Technical Field

[0001] This utility model relates to the field of plasma separator technology, specifically a disposable plasma separator with sample collection function. Background Technology

[0002] A disposable plasma separator is a consumable used in medical blood purification treatment. It is mainly used to separate plasma from blood cell components in the blood through membrane or centrifugal separation technology. Membrane plasma separation utilizes the pore size of hollow fiber membranes or flat sheet membranes to selectively separate plasma as blood flows through them.

[0003] Common plasma separators only separate blood and plasma and transport the blood. After plasma separation, additional sampling is required for testing, which is cumbersome. Therefore, we propose a disposable plasma separator with sample collection function to address these issues. Utility Model Content
