Abstract

The present invention belongs to the field of medical equipment with guard function, and includes safe self-destroying injector and safe needle collector. The injector has integral needle head, needle seat and needle cylinder, and has easy-to-fracture base part for destroying the injector and collecting the needle. After the clamping tooth on the push rod is pushed through the slot inside the cylinder, the needle head will be locked. The needle collector breaks the head to destroy the injector and collect the needle. The present invention can avoid the reuse of the injector and avoid prick of the needle.

Description

Full self-destroyed syringe of safety and safety are ruined the pin needle collector

Technical field: this product relates to a kind of medical apparatus and instruments, is a kind of avoiding by the novel injector with (syringe needle, syringe, push rod) full auto-lock function of using the back syringe needle to be stabbed or re-use and the safety shape destruction needle collector of safe collection syringe needle.

Background technology: this product is improved by the disposable syringe that uses in the present medical institutions.Improved main purpose be lower through new design principle in manufacturing cost, use under more convenient, the safer situation and make medical worker, recovery personnel reduce the occupational exposure chance; Avoid stabbing and cause various blood borne diseases (occupation disease such as infectiousness coronavirus, HIV, hepatitis B, hepatitis C) because of syringe needle; Prevent that also lawless person's secondary from using syringe or its parts (syringe needle, syringe, push rod), guaranteed the safe in utilization of syringe technically through full self-destruction and the design of safety collection pin.

Summary of the invention: in order to overcome conventional injector or its parts (syringe needle, syringe, push rod) contingent needle sting in reusing after the injection or unmaking, collecting, transport; This product solves the technical scheme that its technical problem adopted: 1, cement in the syringe needle fusion on the syringe nipple, the syringe needle root is designed to formula easy to break; On the rib of injector push-rod rear portion, be provided with unidirectional latch; There is the reverse latch (or draw-in groove of indent) of annular convex at syringe inwall scale rear portion; When the push rod front end is shifted the bottom of syringe onto; The push rod latch was stuck in the syringe and can't withdraws from after pushing away syringe internal tooth (or inside groove), and push rod, syringe can not be re-used by locked, and syringe needle also can't be reused by locked simultaneously with syringe.2, the matched portable syringe of the specialized designs collection box for needle or pin that unmakes; Establish a folding papillary duct on the totally enclosed box top; To insert the folding papillary duct of the box that unmakes with the syringe needle point behind the Bi Zisuo; Until syringe needle root (being the syringe pars papillaris) the folding papillary duct that submerges fully, side is broken syringe off with the fingers and thumb and can nipple be fractureed, and the syringe needle that fractures falls into the box and by safe collection and transportation, destruction etc. of unmaking.3, can adopt or design various syringe needle, syringe, push rod according to this principle, be widely used in utensils such as various injections, puncture, pin suction, match, prevent that syringe needle from stabbing, stop secondary and use with safety shape destruction collection box for needle or pin.

Description of drawings: Fig. 1 be full self-destroyed syringe coronalplane of safety and transverse section inject the pre-structure state diagram, can freely take out medicine, aerofluxus.Below Fig. 2: (portable) safety shape destruction collection box for needle or pin.Fig. 3,4,5 is respectively three step sketch maps of typical operation.Fig. 3: the full self-destroyed syringe of safety uses the state before complete self-locking fully, the safety collection pin, and at this moment, injection finishes, and push rod, syringe (comprising syringe needle) all are automatically locked.Fig. 4: the state during safety shape destruction collection pin; (with behind the Bi Zisuo) syringe needle point is inserted the folding papillary duct of collection box for needle or pin; Until syringe needle root (being the syringe pars papillaris) the folding papillary duct that submerges fully, because of the syringe needle root is designed to formula easy to break, side is broken syringe off with the fingers and thumb and can nipple be fractureed from the nipple root.Fig. 5: the state of syringe needle after by safe collection, the syringe needle that fractures fall into the collection box for needle or pin (and in time being collected by safety) that unmakes, and depleted syringe is thrown into other collecting bag or collected in the box.

In the full self-destroyed syringe coronalplane of Fig. 1 safety: icon 1 is the safety injector push rod, and icon a is the latch on the push rod incline.Icon 2 is the safety injector syringe, and icon b is the annular latch in the syringe, and icon c is syringe needle root (being the syringe nipple).Icon 3 is the sealing member of push rod front end, and icon 4 is a syringe needle.In the transverse section: scheming B-B is the vertical view (before injecting) of syringe (annular latch level), and icon d is (on the annular latch) little catch in the syringe, in order to block the latch on the push rod incline, prevents in the transportation because of push or push away self-locking by mistake.Figure B '-B ' be the vertical view (during injection) of syringe (annular latch level), and the rotation push rod makes push rod latch interior (on the annular latch) the little catch d of syringe that staggers, and gets final product one and shifts the end onto.In Fig. 2 safety shape destruction collection box for needle or pin, icon e is the folding papillary duct on the safety shape destruction collection box for needle or pin, and icon f is a groove (be used for adorning sucker or sticker, can place fixing on the spot) at the bottom of the box.Icon g is sucker or sticker.

The specific embodiment: 1, injector push-rod rear portion incline is provided with unidirectional latch a; There is the reverse single-phase annular latch b of convex at syringe inwall scale rear portion; The little catch d of convex more is set on b,, prevents in the transportation because of push or push away self-locking by mistake in order to block the latch on the push rod incline.During injection, the rotation push rod makes push rod latch a (on the annular latch b) the little catch d in the syringe that staggers, and gets final product one and shifts the end onto.The push rod latch promptly is stuck in the syringe and can't withdraws from by b after being pushed over syringe internal tooth b, and push rod, syringe can not be re-used by locked.Cement in because of syringe needle 4 merges with syringe nipple c, syringe needle also can't be reused by locked simultaneously with syringe.Be particularly useful for middle and small hospital, private clinic, enterprises and institutions and chamber, rural health that syringe and parts secondary thereof use the vast developing country be difficult to manage taboo.

2, the special supporting design syringe collection box for needle or pin that unmakes, groove f is provided with plastics sucker or rubber suction cups or sticking two-sided sticker at the bottom of box, can place fixing on the spot.Establish a folding papillary duct e on the totally enclosed box top; Bore can just hold the nipple external diameter, and pipe range will equal or be longer than syringe needle root (nipple) length, and tube wall will have certain rigidity; To insert the folding papillary duct of the box that unmakes with the syringe needle point of Bi Zisuo; Until syringe needle root c (being pars papillaris) the folding papillary duct that submerges fully, side is broken syringe off with the fingers and thumb and can nipple be fractureed from the nipple root, and the syringe needle that fractures falls into the box that unmakes; When safety shape destruction collection box for needle or pin is filled to certain proportion, by safe collection and transportation, destruction etc.Small and light because of box body, groove f can adorn sucker or sticker g at the bottom of the box, is convenient to fix.Can place fixingly at any time on the spot, not limited by the electric power manpower, economize the energy, pollution-free, not only be suitable for fixing injection place and use, be more suitable for the active injection needs of mobile treatment such as country doctor, the disaster relief, epidemic prevention website.
