Device lower end is detachably connected with connecting tube upper end, and piston, push rod are placed in centrifuge tube.Blood plasma in said structure separates and fills
Put complex structure, and blood plasma need to be carried out separate by centrifuge tube, be both needed to be carried out after high cost, and each use and remove
Bacterium, cleaning does not thoroughly easily affect the testing result of blood plasma.
Utility model content
The purpose of this utility model is that provides a kind of disposable plasma separator to solve the above problems.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of disposable plasma separator, deposits pipe, hemofiltration film and plasma collection pipe including whole blood, and described whole blood deposits pipe
Installed above have pressurization lid, and described pressurization covers and is provided with syringe pressurization hole, and described whole blood is deposited pipe lower end and set
It is equipped with described hemofiltration film, described hemofiltration film lower end is provided with described plasma collection pipe, and described plasma collection pipe is mounted below blood
Capping collected by slurry.
In said structure, described whole blood deposits pipe and described plasma collection pipe is aseptic plastic pipe, by anticoagulated whole blood plus
Enter described whole blood and deposit pipe, described pressurization lid is covered and deposits pipe above in described whole blood, syringe needle is penetrated described
Syringe pressurization hole, deposits to described whole blood and pressurizes inside pipe, whole blood under the effect of the pressure, passes through because blood plasma is diluter
Described hemofiltration film, enters described plasma collection pipe, and leukocyte, erythrocyte are then trapped within described hemofiltration film, separates after finishing,
Reverse separator, the capping of described plasma collection is opened, you can convenient extraction blood plasma.
In order to improve the using effect of disposable plasma separator further, described pressurization lid is fixed on by bayonet socket
