Problems solved by technology

However, this needle shield cannot prevent others from reusing after use, that is, after the introduction needle is withdrawn, the spring clip can also be removed from the needle shield without damaging the needle shield or the spring clip, and then replaced. The introduction needle is reinserted into the catheter for reuse

Abstract

The present invention relates to a safety device which is used for a guide pipe and a leading needle component, the safety device is provided with a spring clamp (50), the spring clamp is provided with at least one first clamping part (52), at least one second clamping part (55) and a catch (53), when the leading needle is drew out, the first clamping part is irreversibly meshed with a first clamped part (47) which is arranged on a needle cage (40), the catch (53) moves to the position in front of the distal end of the leading needle, and a limit device (80) can limit the distal end of the leading needle 31 not to move to the outside of the needle cage. The safety device of the present invention can prevent the reuse of the spring clamp, the needle cage or the components.

Description

technical field [0001] The present invention relates to a catheter and introducer needle assembly, and more particularly, to a safety device for a catheter and introducer needle assembly. Background technique [0002] Intravascular catheters, especially intravenous catheters (IV catheters), are usually used to infuse fluids, such as common saline, various drugs, and nutritional injections, etc., to patients, or to draw blood from patients. Peripheral venous catheters are usually short, measuring two inches or less. The most common type of catheter is a peripheral IV catheter over an introducer needle. This over-the-needle peripheral venous catheter is assembled on an introducer needle with a sharpened tip. The catheter and the introduction needle are assembled such that the needle tip of the introduction needle extends beyond the tip of the catheter and the inclined surface of the needle tip portion of the introduction needle faces upward. [0003] The catheter and introd...
