Problems solved by technology

However, for the inspection of biochemical items, the advantages of the existing blood collection tubes are difficult to fully reflect. It needs to first put the blood collection tubes into the centrifuge to quickly separate the serum from the blood cells, and then take the blood collection tubes out of the centrifuge. When the tube body oscillates, tilts, or falls over, it is easy to cause the mixing of serum and blood cells, making further detection impossible

Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] see figure 1 , the embodiment of the present invention includes:

[0016] A disposable negative pressure blood collection tube, comprising: a vacuum test tube body 1, one end of the vacuum test tube body 1 is a closed end, and the other end is sealed and connected with the vacuum test tube body 1 through a sealing plug 2.

[0017] A separation colloid 3 is arranged inside the vacuum test tube body 1, and the separation colloid 3 is fixed at the closed end. The volume of the separating colloid 3 is greater th...

Abstract

The invention discloses a disposable negative pressure blood collection tube comprising a vacuum tube body. One end of the vacuum tube body is a closed end, while the other end is hermetically connected with the vacuum tube body through one sealing plug; a separating gel body arranged inside the vacuum tube body is fixed at the closed end. By the arrangement, blood entering a blood collection tube which is simple in structure can be separated rapidly and automatically, reblending of serum and blood cells is avoided, work efficiency is improved, and cost is saved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a disposable negative pressure blood collection tube. Background technique [0002] Blood collection tubes are widely used due to their convenience, safety and quickness. However, for the inspection of biochemical items, the advantages of the existing blood collection tubes are difficult to fully reflect. It needs to first put the blood collection tubes into the centrifuge to quickly separate the serum from the blood cells. However, after the blood collection tubes are taken out from the centrifuge When the tube body oscillates, tilts, or falls over, it is easy to cause the mixing of serum and blood cells, making further detection impossible. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a disposable negative pressure blood collection tube, which can quickly achieve separation and improve work efficiency. [00...
