Problems solved by technology

[0002] Blood collection tube is a medical device commonly used in hospitals to collect blood for patients. Blood collection tube is generally composed of tube body, rubber plug and cap. Existing blood collection tubes are made of plastic or glass. The tube body of blood collection tube is generally a whole tubular structure, when it is necessary to collect different volumes of liquid, it is necessary to replace the tube body with different specifications and lengths, which brings inconvenience to the use. If a volume-adjustable blood collection tube can be developed, the use flexibility of the blood collection tube will be greatly improved and scope of use

Abstract

The invention discloses a dry and wet separation type blood collecting tube. The dry and wet separation type blood collecting tube comprises a tube body assembly, an inner ring body, an outer ring body, an airbag, a telescopic driving mechanism and a separating mechanism. When the upper tube body floats up and down, an annular drainage plate, an annular telescopic tube and an annular floating plate can be driven to float up and down together at the upper end of the inner ring body, so that liquid flowing out of the upper end of the upper tube body is always discharged from the annular drainageplate of a conical structure with the small upper part and the large lower part into an annular drainage groove, the structure is more stable, and dry and wet separation of the interior of the innerring body is realized.

Description

technical field [0001] The invention relates to a dry-wet separation type blood collection tube. Background technique [0002] Blood collection tube is a medical device commonly used in hospitals to collect blood for patients. Blood collection tube is generally composed of tube body, rubber plug and cap. Existing blood collection tubes are made of plastic or glass. The tube body of blood collection tube is generally a whole tubular structure, when it is necessary to collect different volumes of liquid, it is necessary to replace the tube body with different specifications and lengths, which brings inconvenience to the use. If a volume-adjustable blood collection tube can be developed, the use flexibility of the blood collection tube will be greatly improved and scope of use. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned prior art, the problem to be solved by the present invention is: to provide a dry-wet separation type blood collect...
