[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. In addition, it is necessary to improve the convenience of disassembly and installation

Abstract

The invention discloses a sealed and detachable blood collection device, which includes an air bag, a connecting cylinder, a floating drive mechanism, a blood collection assembly, and an adjustment assembly; the upper end and surroundings of the connection cylinder are closed, and the lower end is open; Blood vessels, connecting rings, sealing rings, tapered elastic ring membranes, lower blood collection tubes, sealed internal thread rings, sealed pressure rings, sealing rings, snap-in sealing rings; the sealing inner parts around the bottom of the tapered elastic ring membrane of the present invention The threaded ring is screwed and connected to the external threaded ring at the upper end of the lower blood collection tube. The sealing pressure ring around the inner side of the bottom of the tapered elastic ring film is tightly pressed against the upper surface of the sealing ring in the sealing ring groove, and the tapered elastic ring film passes through the surrounding area of ​​the upper end. The snap-fit ​​sealing ring is embedded in the snap-fit ​​seal groove around the lower end of the connecting ring, so that the flexible connection between the tapered elastic ring membrane and the lower blood collection tube is ensured while ensuring the sealing, so that the replacement of the tapered elastic ring membrane more convenient.
