Abstract

The invention discloses a safety type blood collection needle structure which comprises a shell, a needle bar fixing rod located in the shell and a blood collection needle fixed to the top end of the needle bar fixing rod. The top end of the shell is provided with a needle outlet. The needle bar fixing rod is disengaged from the shell and arranged inside the shell, or a connector with a gap prone to breakage is arranged between the needle bar fixing rod and the shell. According to the safety type blood collection needle structure, the blood collection needle is fixed into the shell, unreasonable exposure of the blood collection needle before being used can be avoided, when the blood collection needle is used, the tail of the needle bar fixing rod is triggered to push the blood collection needle, or the gap prone to breakage is broken, and the blood collection needle can be pushed to penetrate through the needle outlet to conduct blood collection. The safety type blood collection needle structure is simple in structure and low in cost, the purpose of single hand operation and/or being used with a matched lancing device can be achieved in match with different structures, the safe blood collection operation can be effectively guaranteed, and the safety type blood collection needle structure is applied to the field of medical instruments.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a safety blood collection needle structure. Background technique [0002] The current personal blood collection needles are all disposable.
