Description
Affiliated technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of Disposable, self-destroying safety injector that is used for clinical intramuscular injection or intravenous administration.
Background technology
Along with the medical science technology constantly develops, because of the syringe construction problem, reuse problems such as syringe problem, syringe pollution problem, needle sharing and offal treatment be improper, cause infectious disease transmission even cause.Research institution's statistics according to the ministry of Health of China subordinate shows, the annual injection of China is above 3,000,000,000 times, accounting for has 30% to be dangerous injection in 10% the inoculation, account in 90% the treatment injection 50% and be dangerous injection, hepatitis and acquired immune deficiency syndrome (AIDS) that the whole nation is propagated by dangerous injection make 390,000 Chinese dead ahead of time, and direct medical cost reaches 1.42 hundred million dollars.In known technology, people are in order to address the above problem, and various syringes have been invented in research, have played certain positive role for preventing dangerous injection, but since the increase that these syringes have cost, strengthened medical expense; The increase operational motion that has, the operator is unwilling to use.A kind of syringe is arranged, after injection finishes, when push rod pulls back; entry needle is recessed in the syringe automatically with push rod, and deflection fixedly is fixed against upper wall in the syringe; unlikely being exposed to outward stabbed other people, need not cover the pin lid again, avoided the most dangerous action; as pushing away before the push rod; entry needle is crooked to be damaged in syringe, has destroyed function of injection, can't reuse; simultaneously can prevent accidental needle sticks, protection is injected on the personnel operation and the safety in the offal treatment personnel work.But need injecting personnel's active operation, this syringe could destroy function of injection, otherwise still reusable, can not guarantee disposable use fully.
Summary of the invention
Need inject personnel's active operation and could destroy function of injection in order to overcome existing syringe, otherwise still reusable, can not guarantee disposable deficiency fully.This utility model prevents the piston pumpback after providing a kind of injection intact automatically, and active operation is damaged syringe needle again, can not reusable once more Disposable, self-destroying safety injector thereby guarantee.
The technical scheme that its technical problem that solves this utility model adopts is: this Disposable, self-destroying syringe, mainly form by syringe, syringe needle, push rod, piston, described piston is connected with a T-shaped round platform support, one end of this support inserts piston inner hole, connect by annular convex on its outer wall and the toroidal cavity in the piston inner hole, be laid with three on the other end circumference along syringe curved surface flexure strip longitudinally.The hands side end of described syringe is provided with the dovetail groove along circumference, is provided with the syringe nipple of band endoporus in the middle of the bottom surface of syringe needle side end, and the diameter of this endoporus is slightly less than the diameter of support endoporus; The needle stand outer wall of described syringe needle is cylindrical, so that insert the endoporus of syringe nipple, is laid with three left-handed inclined-plane convexes on the circumferential inner wall of needle stand.Described push rod leading section is an extension bar, be laid with three projections on the end circumference of this extension bar, the diameter that is provided with after the projection is slightly less than the needle stand diameter of bore, and push rod front end outer surface is shaped on 1-2 tooth right-handed thread, matches with 1-2 tooth right-handed thread that the bracket end endoporus is shaped on and connects.Be respectively equipped with on described needle seat outer wall, syringe outer wall, the pusher grip and indicate groove longitudinally, when adjusting and three's sign groove is aligned, three projections that can guarantee the extension bar end interlace 60 ° with three inclined-plane convexes of the needle stand that inserts syringe nipple endoporus.The thickness sum of the length of curved surface flexure strip and piston is slightly less than the length of the interior dovetail groove of syringe to the syringe inner bottom surface, and when needing with assurance, the end of curved surface flexure strip can snap in the dovetail groove.Adopt the syringe of said structure, when assembled syringe was non-working condition, push rod was outwards extracted out less, in order to avoid embed in the syringe oblique groove, influenced push rod and twitched.Take off the needle body guard shield during use, according to normal running the push rod post-tensioning is extracted medicinal liquid, drawing liquid finishes, and promotes push rod forward, air in the tube is discharged liquid medicine injection.Injection is when finishing, and push rod is then shifted the end onto, and this moment, the end of curved surface flexure strip can snap in the dovetail groove, and piston can not pumpback, and syringe can not use for the second time.And the joint on extension bar top and needle stand are combined closely, push rod is changeed 60 ° according to counter clockwise direction, three projections and the needle stand inclined-plane convex of extension bar end are inlayed closely, push rod also breaks away from piston ring, and loosening needle stand, by push rod syringe needle is brought in the syringe thereupon, change the push rod work angle, before push away then and can damage syringe needle, thereby guarantee to prevent to injure the operator and can not reuse once more, the back gets final product according to the disposable medical offal treatment.
As improvement, this utility model Disposable, self-destroying syringe also has a needle stand joint, and the thin end of this needle stand joint is used to install needle stand, and butt end inserts the endoporus of syringe nipple, is laid with three left-handed inclined-plane convexes on the circumferential inner wall of butt end.During use, three projections of extension bar end are inserted in the needle stand joints, and interlace 60 ° with three inclined-plane convexes on its circumferential inner wall, during rotating push-rod, three projections of extension bar end and the inclined-plane convex of needle stand joint are inlayed closely, thereby can bring the needle stand joint in the syringe into together with syringe needle.Set up the needle stand joint, can satisfy the needs that use the different model syringe needle.
As further improvement, the hands side of the described push rod of this utility model Disposable, self-destroying syringe is uniformly distributed along the circumference three grooves is set; The hands side end of described curved surface flexure strip is dihedral, the end embeds in the interior corresponding recesses of push rod during operation, push rod promotes piston to the syringe bottom, the bight of curved surface flexure strip snaps in the dovetail groove, deviate from the push rod groove end, can prevent effectively that the curved surface flexure strip from deflecting, and it is stable to keep push rod when injection, does not influence push rod after injection finishes and extract out.
