Blood taking needle device capable of separating blood taking needle

Abstract

The invention discloses a blood taking needle device capable of separating a blood taking needle. The blood taking needle device comprises a needle tube sleeve, a needle tube, a cannula, a hose, a blood transfusion soft head and a buckle. The connecting depth of the cannula is limited through the limiting circular plate; a limiting circular ring and a connecting column are used for connecting with the cannula; the cannula body can be quickly connected with or separated from the limiting circular ring and the connecting column through the connecting circular plate and the connecting hole; the clamping shaft extends into the circular hole in the upper end of the connecting column, so that the connecting column can be fixedly connected with the connecting circular plate; and the clamping shaft can be quickly pulled out of the connecting column through the oval hole of the clamping plate, so that the connecting column is separated from the connecting circular plate. By means of the invention, the blood taking needle can be rapidly separated, medical staff can collect blood for a patient on the premise that cleanliness and sanitation are guaranteed, the mental and physical burden of the patient is relieved, and meanwhile the production and recycling cost of the blood taking needle can be reduced.

[0002] With the advancement of medical technology, all kinds of advanced medical devices have provided great convenience for people. More and more people have begun to do regular physical examinations. Blood tests are indispensable in the process of all aspects of examinations. ;According to statistics, blood collection needles are currently one of the most consumed medical devices on the market; blood collection needles used in most hospitals are mostly thrown directly into the centralized processing box, but the protective sleeve of the blood collection needle needs to be put into In order to prevent the recycling personnel from being stabbed by mistake, this leads to the medical staff being easily stabbed when the protective cover is put back on, or the recycling personnel are stabbed due to the protective cover not being firmly fixed and falling off during recycling, which greatly increases the number of personnel injuries. chance of infection

[0003] The needles and hoses of blood collection needles are made of different materials. After recycling the used blood collection needles, it is difficult to separate the needles and hoses of the blood collection needles. It takes a lot of work to separate the needles and hoses of two completely different materials. Disposal can make resources be used again, and the cost of recycling increases instead. As a disposable blood collection needle, the cost of recycling will increase the use cost of the hospital and the cost of seeing a doctor for patients. The relationship between doctors and patients cannot be further improved.
