Description
Technical Field
The invention belongs to the technical field of medical appliances, and particularly relates to a blood taking needle holder.
Background
Blood collection needles and blood collection tubes are known as indispensable tools in the blood collection process. In the past, the traditional syringe is commonly used for drawing blood, and then the blood is transferred to a blood collection tube for examination and other operations; in recent years, vacuum tube one-step direct blood sampling is becoming a more advanced blood sampling means. The vacuum tube one-step direct blood sampling adopts a double-head blood taking needle, a needle holder and a blood taking device of a vacuum blood taking tube three-sleeve. The existing needle holder mainly comprises a blood taking needle connecting seat and a blood taking tube outer sleeve, wherein the blood taking needle connecting seat is arranged at the front end of the outer sleeve, after the double-head blood taking needle is installed and fixed, one end of the blood taking needle is positioned at the front end of the needle holder and used for puncturing, and the other end of the blood taking needle is positioned in the outer sleeve of the needle holder and used for being connected with a vacuum blood taking tube to take blood in a matched mode. After blood collection, the needle holder and the double-head blood collection needle can be separated by simultaneous operation of both hands, and the blood collection needle is disposed of, so that the operation is troublesome and complex, and the exposed needle also has a great unsafe factor. If the needle holder and the blood taking needle are not separated, the two sets are processed simultaneously, and the needle holder can be used once just like the blood taking needle, so that the blood taking cost is also increased. In addition, the fixing mode of the existing blood taking needle holder is mainly fixed through a spring or threads and the like, but after the blood taking needle holder is used for multiple times, the joint of the blood taking needle and the needle holder is easy to loosen, the blood taking needle is easy to fall off in the blood taking process, the problem that the blood taking needle is turned and moved in the blood taking process is not well controlled, the working state of the blood taking needle is also not well controlled, and potential safety hazards are brought to blood taking of patients.
