AI Technical Summary
Traditional blood collection needles expose the needle tip after use, which can easily lead to puncture wounds for medical staff and may cause secondary harm to patients.
An arterial blood collection needle was designed, comprising a needle hub and a retraction assembly. By utilizing the linkage of a piston, spring, needle, and blood collection tube, the needle automatically retracts after blood collection through the elastic action of a spring, avoiding needle prick injury. The symmetrically arranged needle holders improve operational stability.
It effectively prevents medical staff from being pricked by needles, reduces patient discomfort, improves blood collection efficiency and operational stability, and reduces the risk of occupational exposure.
