Abstract

The invention discloses an encircling floating-type blood sampling device. The device comprises an air bag, a connecting barrel, a floating driving mechanism and a blood sampling assembly. According to the device, a structure of an original blood sampling tube is changed. An annular cavity is communicated and connected to outside of periphery of a lower end of an upper blood sampling tube, so thatvolume expansion space is arranged to be radial periphery of the blood sampling tube, a problem of overlong height and inconvenient operation caused by axial distribution is avoided. When a connecting ring, a sealing ring, a conical floating ring sleeve and a lower blood sampling tube are driven upwards together by the floating driving mechanism, an overlapping part of the annular cavity and theupper blood sampling tube is increased, so that blood sampling space is compressed, and when the connecting ring, the sealing ring, the conical floating ring sleeve and the lower blood sampling tube are driven downwards together by the floating driving mechanism, the overlapping part of the annular cavity and the upper blood sampling tube is reduced, so that the blood sampling space is enlarged. The encircling floating-type blood sampling device has ingenious structure design and convenient adjustment.

Description

technical field [0001] The invention relates to a surrounding 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] Aiming at the shortcomings of the above-mentioned prior art, the problem to be solved by the present invention is: to provide a surrounding floating blood collection device ...
