The specific embodiment
As Figure 1-3; the safe intravenous infusion indwelling needle assembly comprises needle tube sheath 1, indwelling needle assembly 3, tubulose safety protective cover body 2 and piercing assembly 4; described piercing assembly 4 comprises needle tubing seat 402 and piercing needle 401; piercing needle 401 is fixed on needle tubing seat 402 front ends; indwelling needle assembly 3 comprises catheter block 302 and inlying catheter 301; inlying catheter 301 is fixedly installed on catheter block 302 front ends, and catheter block 302 sides are provided with puncture needle wings 303, can be one or both sides.Protective sleeve body 2 is circular tube shaped in this specific embodiment, and length is longer than piercing assembly 4, to guarantee that piercing assembly 4 is hidden in inside fully.Described needle tube sheath 1 and catheter block 302 clampings, described needle tube sheath 1 removably connects with catheter block 302, needle tubing seat 402 can be truncated cone cylindrical or that front end is smaller, the diameter of needle tubing seat 402 cooperates with safety protective cover body 2 inner bore diameter clearance, described piercing assembly 4 can be arranged in protective sleeve body 2 inner chambers axially slidably, described piercing assembly 4 has the dormant state that is in the inner chamber front end and is in the rear state of using of inner chamber the inner in protective sleeve body 2 inner chambers, safe intravenous infusion indwelling needle assembly 3 also is provided with flexible restoring organ or latching device and pressing type tripping mechanism, in this specific embodiment, be arranged with Compress Spring 5 at described needle tubing seat 402, described needle tubing seat 402 rear end surfaces are provided with the shoulder rank, described Compress Spring 5 rear ends are against on the described shoulder rank, Compress Spring 5 front ends are against on the inwall of protective sleeve body front end and make described piercing assembly 4 have the elastic force of piercing assembly 4 being pushed to inner chamber the inner under dormant state, consist of thus described flexible restoring organ, as shown in Figure 4; Certainly; an extension spring can also be set in the inner of protective sleeve chamber body; one end of extension spring is connected on the described needle tubing seat 402, and the inner that the other end is connected to the protective sleeve chamber body consists of described flexible restoring organ, but this structure can cause the protective sleeve body length to lengthen.Described protective sleeve body 2 is provided with guide chute 201 vertically; described needle tubing seat 402 outer walls are provided with radial projection 4021; described projection 4021 matched in clearance in guide chute 201 and the end be exposed at outside the protective sleeve body 2; be provided with vertically seesaw spare on described protective sleeve body 2 outer walls; preferably near front end; corresponding with the position of needle tubing seat 402 under the dormant state; described seesaw spare 6 is provided with the hook 601 that matches with projection 4021 with corresponding section, described projection 4021 position on an end of protective sleeve body 2 rear ends; hook 601 is towards protective sleeve body 2 tube walls; described hook 601 catches on the inner that projection 4021 stops piercing assemblies 4 to slide to protective sleeve body 2 inner chambers and consists of described latching device; described seesaw spare 6 other ends are release end 602; need leave the gap of pressing between release end 602 and protective sleeve body 2 tube walls; thereby consist of described pressing type tripping mechanism; when pressing release end 602; the other end upwarps; hook 601 breaks away from projection 4021; piercing assembly 4 can slide to the inner of protective sleeve body 2 inner chambers and be protected, as shown in Figure 5.Safety intravenous infusion indwelling needle assembly is not only easy to use; and since piercing assembly 4 behind the inner that slides to the protective sleeve chamber body; piercing needle 401 also is in the Compress Spring 5 simultaneously, expose the absolutely not guide chute 201 from protective sleeve body 2, so safety is higher.Cause original piercing assembly 4 to slide to protective sleeve body 2 interior intracavity in order to prevent owing to bumping release end 602 by mistake; described release end 602 is near needle tube sheath 1, and described needle tube sheath 1 is provided with the block 101 of pressing the below that extends to release end 602 towards release end 602 1 sides.Certainly; latching device neither be unique; also other modes can also be arranged; as: as described in needle tubing seat 402 be provided with the radial spring cavity volume; be provided with successively helical spring and column unlock button in the described radial spring cavity volume, under the dormant state, position corresponding with the radial spring cavity volume on the protective sleeve body outer wall is provided with button hole; described unlock button end passes from button hole exposes, and described unlock button exposed parts is that the inclined-plane arranges the described latching device of formation towards protective sleeve body tip one side.After finishing the puncture action; only need singlehanded capable of being unlocked by pressing button; unlock button is pressed towards the radial spring cavity volume; when in being depressed into chamfered portion and button hole, contacting; because the elastic force of Compress Spring 5 and the effect on inclined-plane on the described needle tubing seat 402; thereby unlock button can further be moved back release in the spring cavity volume radially, and piercing assembly 4 can slide to the inner of protective sleeve chamber body and be protected.
