AI Technical Summary
Existing blood sampling methods have drawbacks such as the risk of needle prick with syringes and the need for two people to operate them, and the frequent unscrewing of the cap is labor-intensive.
A blood bottle opening device including an electric screwdriver and an opening sleeve was designed. The opening sleeve enables single-person operation through a clamping spring and anti-slip ridge structure, while the electric screwdriver provides rotational force to unscrew or tighten the blood bottle cap.
It enables single-person operation, safely and efficiently opening and tightening blood bottle caps, reducing manual labor costs and avoiding needle prick risks and frequent operations.
