Therefore, there are many kinds of self-destructive syringes with different structures. However, many of them have extremely complicated designs, which are too expensive or difficult to operate and cannot be widely used. In addition, there are some simple designs, but It may cause major problems such as poor correctness of the injection, or it can still be used repeatedly, or it can be easily recycled for use after disposal. [New content] 15 In view of the above-mentioned shortcomings, the applicant has painstakingly developed the self-destructing self-destructing syringe of this creation, which can achieve the following creation purposes. The main purpose of this creation is to provide a stopper forced self-destructing injector that can keep the stopper inside the syringe after injection and prevent repeated use. 2〇 A second objective of this creation is to provide a stop-and-stop self-destructing injector, which can facilitate the manufacture of components, and facilitate assembly and operation. In order to achieve the purpose of the previous disclosure, this creation provides an anti-blocking and self-destructing syringe, which is connected with a needle. The syringe includes a syringe with a straight body and a receiving hole. The part is continued from the receiving hole to the next page (when the new instruction page is not enough, please note and use the continuation page) -4- M257835 New Manual $ Selling page is formed in the direction of the needle. A hand-held ear is provided at the rear end of the barrel; a forcing member is provided at the inner end of the receiving hole of the syringe, the forcing member has a tube body formed with a rod insertion hole, and a liquid communication hole communicates with the syringe An accommodating hole and an infusion hole, and an inserting edge; a putter 5 has a shaft into which a receiving hole for the syringe can be inserted, an abutment portion is located at the front end of the shaft, and a plug portion is connected to the rod Body, a push-pull part is provided at the rear end for finger push-pull; a stopper has a plug body sealingly moving in the receiving hole of the syringe '; a post hole is correspondingly sleeved on the plug-connecting part of the push rod, The post hole can be inserted into the pipe body of the forcing member by its insertion edge. 10 [Embodiment] In order to better understand the characteristics and effects of this creation, the following examples are illustrated together with the illustrations as follows: Please refer to the first to sixth pictures, a preferred embodiment of this creation Type self-destructing syringe, which is connected with a needle (N); the syringe includes: a syringe (10), a cylinder (11), a receiving cylinder (12), a thrust part ( 13) Connected to the cylinder body (n) is formed by the accommodation hole (12) in the direction of the needle (N), a needle connection part (15) is provided for the installation of the needle (N) and an infusion hole (16) is opened, A hand-held ear (17) is connected to the rear end of the cylinder body (11), and a push rod stop 20 edge (18) is provided near the opening of the accommodation hole (12). A stopper piece (20) is provided at the inner end of the accommodation hole (12) of the syringe (10); the stopper piece (20) has a tube body (2 丨) with a sleeve portion (22) ) Is integrally connected to the inner edge of the accommodating hole (12) of the syringe (10), and a rod insertion hole (23) axially penetrates the official body (21) 'a number of liquid-through holes (24) communicate with the needle The receiving hole (12) of the cartridge (10) -5- M257835 New Manual $ Selling stomach and infusion hole (16), and a plug edge (25). —The push rod (30) has a shaft (31) into which the receiving hole (12) of the syringe (10) can be inserted, an abutment portion (32) is located at the front end of the shaft (31), and a stable plug A portion (33) is connected to the shaft (31), a neck portion (35), a plug portion (36) is connected to the formation 5 to the neck portion (35), and a plurality of concave and convex patterns (361) are provided on A push-pull portion (37) is provided on the outer periphery of the plug-receiving portion (36) at the rear end for finger push-pull. A stopper (40) is made of a material such as rubber and plastic, and has a plug body (41). A two-cylinder sealing edge (42) is formed on the plug body (41) and moves in a sealed manner on the syringe (10). The accommodation hole (12), a stabilizing rod hole (43) are sleeved on the stabilizing 10 plug portion (33) of the push rod (30), and a rod sealing edge (44) is formed on the inner edge of the stabilizing rod hole (43). A neck hole (45) and a post hole (46) are respectively corresponding to the neck (35) and the plug part (36) of the push rod (30), and an insertion hole (47) is available. The pipe body (21) of the forcing member (20) is inserted into the post hole (46). The operation of this embodiment is described as follows: 15 As shown in the third figure, it is the state of the combined installation before being used; and as shown in the fourth figure, the push rod (30) drives the stop The plug (4〇) is pulled back to a predetermined position, which is the same as the state of drug withdrawal. Next, during the injection operation, as shown in the fifth figure, the pusher (30) is pushed to the bottom, so that the stopper (40) injects the medicine solution from the needle; among them, the stopper member 20 (20) The insertion edge (25) at the front end of the pipe body (21) is inserted into the post hole (46) through the insertion hole (47) of the stopper (40), and the plug body (41) of the stopper (40) is subjected to The compression deformation is forced between the accommodation hole (12) of the syringe (10) and the tube body (21) of the forcing member (20). At this time, the plug portion (36) of the push rod (30) is separated from the plug hole (46) of the stopper (40), but the plug portion (33) of the push rod (30) is stable. With the stopper (40) -6-M257835 new instruction manual, the rod hole (43) and rod sealing edge (44) of the new model still maintain a good sealing effect without leaking the medicinal solution backward. Finally, as shown in the sixth figure, the stopper (40) is fastened and clamped on the inner end of the accommodation hole (12) of the syringe (10), and the push rod (30) can be Pull back 5 times easily without moving the stopper (40). Therefore, it is in a self-destructing state, and the syringe (10) and stopper (40) of this injection can no longer be used, and it has the safety of preventing reuse.

The above-mentioned one or a combination of structures has a variety of methods, which will not be described in detail. Another preferred embodiment of this creation, as shown in Figures 8 and 9, shows that it is a syringe with a manual pull-back needle; it is substantially the same as the previous embodiment, except that the pusher is more It has a needle base hook (39); the syringe further includes a needle base (50) mounted on the needle receiving part of the syringe, the needle base (50) has a body (51) and a pull-back hook part (53) It can be pulled by the needle holder hook (39) of the push rod (30), so that the needle holder (50) and the needle can be pulled back to the accommodating hole of the syringe. -7- ^ 35 New Manual $ 卖 Μ In addition, there is a convex hook (27) on the front end of the needle stopper of the syringe, and a stopper edge (48) is also formed on the stopper of the syringe. ) May be supported by the convex hook (27) to assist in stopping the stopper. This creation shows that the display factory and another preferred embodiment, as shown in the tenth and eleventh diagrams, are roughly the same as the syringes with spring-retracted needles; the difference from the previous embodiment is that the spring automatically Retractable needle, in which: the elastic tube has a retracted abutment (19), the retracted abutment (19) has a (55) / 9 ^ and a retracted abutment (193); the needle seat There is even a retracted abutment for the retracted abutment portion (193) of the side syringe. In the seat, the main shooter further includes a spring (60) mounted on the syringe and needle (70), and a retraction control member (70) is sleeved on the syringe; the retraction control member The fc (73) of the variable control crotch is an escape hole for the retracting abutment (19) 15 of the syringe. When used, the retracting control member is rotated to make the retracting of the syringe abutable. The needle seat is elastically deformed to its control part (73), and the bullet seat () can be used to elastically retract and retract the needle seat to the receiving hole of the syringe. According to the above embodiments, the characteristics of this creation can be summarized as follows: I. This creation is a stop-stop, self-destructing syringe, which can be stopped after injection.
