Background technology
Syringe and syringe needle are widely used injecting apparatus; Yet in actual use, can produce needle point unavoidably and stab accident; This all is a potential danger for doctor, nurse, nurse and for colony that syringe contacts.Because modern medicine proves have tens of kinds of diseases can pass through blood propagation,, might stab because of accidental needle and obtain infection comprising AIDS, hepatitis or the like.In addition, the present disposable aspiration needle that generally uses is reused after might being stolen by junkie or other lawless person after throwing aside, thereby is caused pathophoresis.Design and develop a kind of avoid accidental puncture and use after can be by locked, the unlikely safe syringe set that is repeated to use has become one of important topic that current prevent disease propagates.
Various countries hygiene department has set about making an effort in recent years, to scheme to reduce and even eliminate this threat; And the safety needle of existing various structures is is constantly researched and developed appearance.Americanologist had been crossed the safety needle bill in 2000, and explicit stipulation medical institutions should safe in utilizationly install, to reduce the possibility that acupuncture accident takes place for medical and nursing work person and sufferer in using the syringe process.
Chinese patent application file (application number 01218894.8) discloses a kind of safty pin skull 11 (seeing Figure 20) of syringe.The structure of this needle cover is the long grooving that is shaped on a longitudinal opening in the periphery of a thin wall casing that adapts with the syringe needle shape, and this slot length and syringe needle adapt and laterally receive in the sleeve pipe for syringe needle.During use, user can laterally embed syringe needle in this needle cover and intercalation is fixed; Can obviously reduce the generation of acupuncture accident like this.The deficiency of this needle cover is: need with the hands comparatively trouble of operation simultaneously during use; In addition, needle cover separates with syringe needle easily as an individual components, thereby tight inadequately to the effect of screening of syringe needle, and security performance is not strong.
Summary of the invention
The present invention seeks to overcome the deficiency of above-mentioned background technology, a kind of improvement of safty pin skull is provided, this needle cover should have the syringe needle of can tightly screening, good, the easy to use flexible characteristic of security performance.
Another object of the present invention is that this needle cover should be by locked after use, unlikely being reused.
The technical scheme that the present invention has adopted is: safe syringe set, comprise a pinhead sleeve, and injection needle or injection needle socket; The rear wall of pinhead sleeve is shaped on the long grooving that a longitudinal extension and length and syringe needle adapt; It is characterized in that described injection needle or injection needle socket all embed in the block set that is fixed on a up/down perforation, the place ahead of block set is made uncovered, about be shaped on the chute that above-below direction extends on two seat walls, the top of chute is shaped on the little fork to uncovered direction bending; The bottom of described pinhead sleeve is shaped on two clamps that keep at a certain distance away and be shaped on a straight trough respectively, two clamps down stretch and are parallel with the pinhead sleeve axis, and two clamps are also fixed a pin that embeds described chute respectively makes pinhead sleeve be movably connected on block set; The uncovered position of described block set also is provided with a push pedal that can slide up and down along uncovered edge, the head-bent of push pedal stretches between two clamps, two pins of head embed respectively in the straight trough of two clamps and are slidingly matched, so that moving up and down of push pedal converts the rotation of pinhead sleeve around block set to; Also be provided with an elastic strip on the described pinhead sleeve, the two ends of this elastic strip are connected with the front side of pinhead sleeve inwall respectively and are connected with the needle stand or the injection needle socket of injection needle, make pinhead sleeve have the potential energy that rotates around block set automatically to apply elastic pulling force.
Described pinhead sleeve periphery also wears a rotating case, and the wall portion of this case is shaped on the long grooving that a longitudinal extension and length and syringe needle adapt; With the long grooving that blocks as required on the pinhead sleeve syringe needle is hidden protection, perhaps the long grooving that puts of exposed needle is convenient to syringe needle and is laterally shifted out.
The top of described pinhead sleeve is made outstanding, so that the case that is set on the pinhead sleeve is obstructed and can't slips away.
The uncovered position dual-side of described block set is made arc along the lower semisection of bead, so that the edge, the left and right sides of push pedal carries out movement in a curve after embedding bead.
Go back horizontal fixed one blend stop on the described block set, an elasticity volume bar that matches with described blend stop is then fixed in the back of push pedal, and elasticity volume bar also is shaped on return bend; So that colluding, return bend holds the lock structure that forms needle guard behind the described blend stop.
Straight trough on described two clamps is parallel with the axis of pinhead sleeve respectively.
Use principle of the present invention is as follows:
1, resting state: each position component as shown in figure 14 at this moment.
2, opening process: earlier this safe syringe set is set on (as shown in figure 20) on the syringe 5, then rotates case 1 the long grooving 1-1 on the case is alignd with the long grooving 2-1 of pinhead sleeve 2; User can be held syringe by one hand then, with the thumb 3a position of (direction shown in the arrow A among Figure 15) pushing tow push pedal 3 forward, make its drive pulling force that pinhead sleeve overcomes elastic strip along the bead on block set dual-side edge to front slide (sliding among the chute 4-1 of pin 2-31 on the pinhead sleeve clamp simultaneously) in block set; Because bead is curved, so push pedal and pinhead sleeve also move toward uncovered direction (right direction of Figure 15) in the time of front slide; When pinhead sleeve advanced certain distance, the pin 2-31 on the pinhead sleeve clamp just slipped into chute 4-1 to the right in the little fork 4-11 of uncovered direction bending (being to bend among Figure 15); After this when the thumb of user unclamps pushing to push pedal, because pin 2-31 can not be moved down by jacking at the place, little fork of chute 4-1, pinhead sleeve just clockwise rotates under the pulling force effect of elastic strip, and the syringe needle in the pinhead sleeve also begins laterally to deviate from (shown in Figure 16) from the long grooving 2-1 of syringe needle jacket wall portion; Clockwise rotate more than 90 degree until pinhead sleeve, the syringe needle in the pinhead sleeve is also fully laterally deviate from (shown in Figure 17) from the long grooving 2-1 of syringe needle jacket wall portion; So just can carry out conventional injection operation.
3, close closed procedure: after the injection operation was finished, user still can be held syringe by one hand, with the 3b position of thumb pushing tow push pedal forward 3, pinhead sleeve again backward rotation to original position, make syringe needle once more laterally from long grooving 2-1 enter in the pinhead sleeve; Thumb unclamps push pedal then, and in the pulling force of elastic strip and stopping under the cooperation of thumb, the pin 2-31 on the pinhead sleeve clamp 2-3 just enters the chute 4-1 on the block set and moves down along this chute, and whole pinhead sleeve moves down and drops down onto original position (Figure 14 position); Then, only need rotate case 1 once more the long grooving 1-1 on the case and the long grooving 2-1 of pinhead sleeve 2 are staggered, the long grooving of pinhead sleeve be blocked sealing fully get final product.
4, lock-out state: when safe syringe set is in Figure 14 position, pull back push pedal 3 to SBR (shown in Figure 180) with thumb; And then the application of force presses down and the 3b position of the push pedal 3 of pulling back, and makes blend stop 7 on the block set slip into return bend 8-1 (shown in Figure 19) on the elasticity volume bar 8; Because return bend colludes the pulling blend stop reach of push pedal is obstructed, pinhead sleeve has obtained locking because of moving.
The invention has the beneficial effects as follows:, thereby use fool proof because this safe syringe set can block syringe needle reliably; And only need singlehandedly make just this safe syringe set of energy opening and closing of operation, more convenient and flexible during use, can significantly improve the efficient of injection work; In addition, adopt pin chute syndeton between several parts of this safe syringe set, be connected firmly, protection is reliable; Add the lock structure that is disposed, avoided illegally re-using of syringe needle effectively, prophylactic propagation is had very positive meaning.
