Description

Multifunctional blood collection tube

Technical Field

The utility model relates to a medical consumptive material technical field especially relates to a multi-functional heparin tube.

Background

With the progress and development of modern medicine, rapid in vitro testing and diagnosis is a trend, and blood sampling assay as a conventional and necessary way plays an important role in diagnosis and treatment of diseases and prognosis judgment.

Substances in blood are often required to be separated after the blood collection process is finished, blood cells are damaged in a conventional centrifugal separation mode, so that the blood cells are difficult to collect, and the blood plasma separation operation on the upper layer often causes the blood cells to be sucked to the blood cell layer by mistake to influence the experimental result.

Among the prior art, the separation of plasma and blood cell adopts interior outer tube structure more, and the position between the interior outer tube of heparin tube leans on the plug fixed, but this kind of connection is not firm, and when plug elasticity is not enough or open the plug in-process, the blood sampling inner tube often can be because with the plug between the frictional force not enough and drop in the outer tube body, lead to the blood sampling failure, the blood cell filters out the back because be in interior tube body messenger's separation operation difficulty. In the relevant heparin tube, blood sample handles and need to open the plug and operate, and this just needs plug and mouth of pipe to be active connection, because blood collection back, the vacuum in the body disappears, and the blood taking needle pierces and takes out the plug easily when plug end is pulled out, causes blood pollution, threatens medical personnel's safety simultaneously.

Therefore, it is necessary to provide a new multifunctional blood collection tube to solve the above technical problems.
