The specific embodiment
Below in conjunction with the specific embodiment, further set forth the present invention.
As shown in Figure 1, it is a kind of needle puncture-preventing remaining needle of the present invention, remaining needle needle stand 5 is connected with catheter block 4, catheter block 4 front end fixed sleevings 2, in the middle of the sleeve pipe 2 is needle tubing 1, needle stand 5 other ends connect exhaust joint 6, exhaust joint 6 has head protector 7, as shown in Figure 2, be provided with an elasticity needle point guard spare 9 in the catheter block 4, needle tubing 1 passes this elasticity needle point guard spare 9, and the needle tubing card that needle tubing 1 is provided with is mixed 13 diameters greater than the hole of threading a needle on these elasticity needle point guard spare 9 rear walls, and this elasticity needle point guard spare 9 is provided with the needle point guard card and mixes 14, this needle point guard card is mixed 14 and be may be stuck on the catheter block draw-in groove 15 that catheter block 4 rear ends are provided with, when needle tubing 1 when catheter block 4 is extracted, this needle point guard card mixes 14 can break away from catheter block draw-in groove 15, elasticity needle point guard spare 9 is extracted catheter block 4 together with needle tubing 1 parcel and needle tubing 1.
As Fig. 3, shown in 4, elasticity needle point guard spare 9 front end needle tubings 1 perforating position can close structure for opening, after the closure, these elasticity needle point guard spare 9 leading portions become the cylindrical shape of closure of openings, the rear wall of this elasticity needle point guard spare 9 is a plane, rear wall is provided with the hole of threading a needle, when needle tubing 1 is drawn out in catheter block 4, the needle tubing card is mixed 13 and is blocked and elasticity needle point guard spare 9 is taken out of by the hole of threading a needle of needle point guard spare 9 rear walls, the needle tubing card mix 13 blocked by the hole of threading a needle on elasticity needle point guard spare 9 rear walls and elasticity needle point guard spare 9 taken out of in, the needle point of needle tubing 1 all recedes into needle point guard spare 9 inner chambers, and the front end of elasticity needle point guard spare 9 closes up under the elastic reaction that designs needle point wrapped, and needle point can not be passed again.Mix the draw-in groove 15 of 14 places (mixing 14 draw-in grooves 15 that are stuck in catheter block 4 in) disengaging catheter block 4 and taken out of by needle tubing 1 easily when elasticity needle point guard spare 9 front ends close up needle point guard spare card when needle point wrapped, thereby reach the purpose of preventing pricking wound because needle point struts elasticity needle point guard spare 9 front ends when stretching out needle point guard spare card then.
Be provided with the fixed core 8 of fixed sleeving 2 among the present invention in the catheter block 4, fixed core 8 is inserted an end of sleeve pipe 2, and catheter block 4 front ends embed catheter block 4 inner chamber fixed sleevings 2 by fixed core 8 with sleeve pipe 2.
Shown in Fig. 5,6,7,8, two embodiment in addition of the present invention, catheter block 4 has activity or fixed tab 3.
Shown in Fig. 9,10, another embodiment of the present invention, on the described catheter block 4 dosing mouth 13 is arranged, dosing mouth 13 is communicated with needle tubing 1 inner chamber, and on catheter block 4, be provided with feather valve pipe 16, this feather valve pipe 16 can be communicated with dosing mouth 13 with needle tubing 1 inner chamber passage sealing and unlimited, dosing mouth 13 opening parts have dosing mouth helmet 12.
The concrete working method of feather valve pipe 16 is among the figure: because of dosing mouth 13 is medicine to be flowed into intravitally by inner chamber, and dosing mouth 13 and inner chamber lead to, and feather valve pipe 16 is exactly the hole that dosing mouth 13 leads to inner chamber to be blocked (in the strong attitude of transfusion) by self elasticity.When with syringe when dosing mouth 13 dosings, push away at syringe and to back down feather valve pipe 16 under the effect of medicine pressure medicine is injected, when having annotated medicine and do not have pressure, feather valve pipe 16 seals the hole with the elasticity of self and is not directed at medicinal liquid and outflows.
Through evidence, a kind of anti-adverse current remaining needle of the present invention has solved the problem of using the blood back flow of remaining needle really, has remedied the deficiencies in the prior art.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
