Blood collection test tube

Abstract

The invention discloses a blood sampling test-tube. The sampling test-tube comprises a tube body, wherein a conical cylinder is arranged in the tube body, and a plurality of strip-shaped grooves are formed in a side surface of the conical barrel. By adopting the technical scheme, the blood sampling test-tube can store a separated serum sample in an inner cavity of the conical barrel, so that the liquid surface of serum is relatively high, and the serum sample can be easily detected by a serum detection instrument.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a blood collection test tube. Background technique [0002] At present, in the medical and health industry, the utensils used to collect whole blood are generally disposable blood collection tubes, because the detection of many items requires only serum, if the serum and blood cells cannot be separated in time, it will cause serious damage to the results of many testing items Therefore, it is particularly important to preserve the separated serum. [0003] Serum separation gel is a viscous fluid, its structure contains a large number of hydrogen bonds, and a network structure is formed due to the association of hydrogen bonds. Under the action of centrifugal force, the network structure is destroyed and becomes a fluid with low viscosity. When the centrifugal force disappears, the network structure is re-formed. It returns to a high-viscosity fluid. This property is called th...

Problems solved by technology

[0004] At present, the utensils commonly used to preserve the separated serum are mainly disposable plastic centrifuge tubes (commonly known as "disposable plastic bullets") and other types of disposable test tubes, but these existing test tubes have the following defects: first, due to a The volume of permanent plastic centrifuge tubes is generally only 0.5-1.5ml, because the volume is too small, it is easy to lose, and the cover is not well sealed, which may easily lead to liquid leakage and pollution; secondly, although other types of disposable test tubes use rubber stoppers, the sealing performance is basically It can be guaranteed, but often due to the limited volume of separated serum, the liquid level of serum samples stored in other types of disposable test tubes is too low, which makes it difficult for many precision instruments for detecting serum to detect serum samples, so the serum must be manually separated. The sample is sucked into the reaction cup, and then tested by the serum testing instrument, which brings the inconvenience of serum testing
