AI Technical Summary
The existing connection method between the infusion set and the infusion bottle is prone to detachment due to pulling, which affects the treatment effect.
An infusion set with an anti-drop buckle was designed, comprising a clamping component and a control component. The infusion set clamps the bottle stopper by expanding and contracting the clamp plate, and uses an elastic cord to connect the infusion set to the infusion bottle to prevent it from falling off.
It effectively prevents the infusion set from separating from the infusion bottle, avoids the needle from contacting non-sterile areas, and improves adaptability and safety during use.
