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 a tube body and a cap. Existing blood collection tubes are made of plastic or glass. The tube body of a blood collection tube is generally an integral 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 flexibility and range of use of the blood collection tube will be greatly improved.

Abstract

The invention discloses a radial and axial double-floating blood collection device, which includes an air bag, a connecting cylinder, a floating drive mechanism, a blood collection assembly, and an adjustment assembly; When the ring rotates upwards on the lower blood collection tube, the extrusion ring moves upward, so that the extrusion ring squeezes the conical elastic ring film into the inner side of the extrusion ring, so that the conical cavity "temporarily disappears", thereby discharging The air in the conical cavity, and then send the lower end of the lower blood collection tube into the blood collection container, and then adjust the internal thread ring to rotate downward on the lower blood collection tube to drive the downward movement of the extrusion ring. The high-elastic conical elastic ring The membrane will recover quickly, so that the conical cavity "reappears". At this time, the air bag is released, and the liquid can be pressed into the upper blood collection tube, the lower blood collection tube, and the conical cavity, so that the exhaust function is realized. Use more convenient.

Description

technical field [0001] The invention relates to a radial and axial double floating blood sampling device. 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 a tube body and a cap. Existing blood collection tubes are made of plastic or glass. The tube body of a blood collection tube is generally an integral 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 flexibility and range of use of the blood collection tube will be greatly improved. . Contents of the invention [0003] In view of the shortcomings of the above-mentioned prior art, the problem to be solved by the present invention is: to provide a radial and axial double-floating...
