The invention discloses a disposable rebound safety blood drawing bag, which comprises a blood drawing part, a reserved sample part and at least one blood bag which are sequentially connected. The blood drawing part comprises an outer cover, a core rod and a blood taking needle. The core rod is inserted in the outer cover, the blood taking need is connected with the lower end portion of the core rod, the blood drawing part further comprises a piston and a needle sleeve, a ring of clamp groove is arranged on the outer wall of the core rod, the piston is clamped between the clamp groove and the outer cover, and the core rod is driven to move relative to the outer cover through the relative movement between the piston and the outer cover. The needle sleeve is sleeved on the lower portion of the core rod and is sleeved on the blood taking needle. The blood drawing part, the reserved sample part and at least one blood bag are respectively and externally connected with a conduit, and the conduits are connected to form a whole through a three way valve. The disposable rebound safety blood drawing bag can effectively avoid puncture accidents of the blood taking needle and greatly reduces medical risks.
Description
technical field [0001] The invention relates to a medical device, in particular to a disposable retractable safety blood collection bag. Background technique [0002] Blood collection bags are currently one of the most sold medical devices in the world. However, it is worth noting that there are millions of human injury accidents caused by broken needles or improper operation of medical staff in hospitals around the world every year. Statistics released by the American Medical Association show that in the United States alone, about 1 million medical staff are accidentally injured by blood collection needles every year, and at least a thousand of them will be infected by hepatitis B virus, hepatitis C virus and HIV attached to the needle. The cost of emergency treatment for medical staff and patients who were stabbed by a broken blood collection needle was US$3,000 per capita. [0003] The medical risks caused by ordinary blood collection needles will not be lower than thos...
