Abstract

The invention relates to a disposable centrifugal type plasma separator; a hemostix, a plasma filter pipeline, a separation cup and a blood storage bag are connected to form a transport channel in sequence; the hemostix comprises a blood taking needle and a catheter which is connected with the blood taking needle; the catheter is provided with a stop flow clip; the plasma filter pipeline comprises a puncture outfit, a blood filter and an air filter; the inputs of the puncture outfit and the blood filter are respectively connected with a tee interface by the catheter; the other end of the tee interface is connected with the catheter in the hemostix; the air filter is connected with one output of the blood filter by the catheter while the other output of the blood filter is connected with the input of the separation cup by the catheter; and the output of the separation cup is connected with the blood storage bag by the catheter. The invention has the advantages that as the disposable plasma collection consumables which are singly packaged originally are assembled, packaged and sterilized in the same purified environment, the risk of sterility connection for the parts is greatly reduced, and the workload of medical personnel is decreased, too.

Description

technical field [0001] The patent of the present invention relates to the relevant technical field of medical devices, in particular to a disposable centrifugal plasma separator. Background technique [0002] Existing domestic collection of human plasma is completed by supporting blood collection devices, plasma pipelines, separation cups, plasma bags, and plasma collection machines. The current medical device companies are all producing and packaging blood collection devices, plasma lines, separation cups, and plasma bags separately, and aseptic connection is required during use, which increases the risk. And the patent of the present invention sterilizes the blood collection device, the plasma pipeline, the separation cup, and the plasma bag after being connected in the purification workshop. It greatly reduces the risk of accessories during aseptic connection and reduces the workload of medical staff. Contents of the invention [0003] The purpose of the patent of the...
