Abstract

The utility model provides a symmetrical arrangement has first ring and second ring on pulling injector's the injection syringe, is provided with the third ring on pushing away the handle, and three ring can hold three fingers, makes extraction that operating personnel can singlehanded completion liquid medicine and injects, has avoided the delay of time. Still being provided with the lantern ring on the injection syringe, playing the effect of control push rod stroke, can not make the plug deviate from the injection syringe, guarantee that the injection syringe inner chamber does not have external gaseous entering, moreover, just the medicine is injected when finishing at once, and the lantern ring can contact with the third ring, and the lantern ring blocks that it continues to inject forward to push away the handle, and at this moment, the plug leaves proper amount safe space with the bottom of injection syringe, has guaranteed the interior a small amount of gas of injection syringe and can not follow the liquid outlet and enter into other medical equipment. The liquid outlet and the circular cone locking male joint of injection syringe peg graft, and the inner wall of circular cone locking male joint's the other end has screw thread locking mechanical system, can other medical equipment screw threads lock connection.

Description

A kind of injector

Technical field

This utility model relates to medical instruments field, particularly relate to a kind of for injection liquid or The injector of contrast solution.

Background technology

Coronarography is the one of diagnosis coronary atherosclerotic heart disease (coronary heart disease) Plant conventional and effective method, need during radiography contrast solution is injected into cardiovascular, Thus can clearly the lumen of vessels of trunk coronarius for whole left or right and branch thereof be shown Illustrate, it will be appreciated that blood vessel exists with or without stenotic lesions, to diseased region, scope, serious Degree, the situation etc. of blood vessel wall are made and being clarified a diagnosis, determine therapeutic scheme (get involved, perform the operation or Medical treatment), may further be used to judge curative effect.Generally need to use during injecting contrast solution The contrast solution making outside to utensils such as syringes enters into cardiovascular, but common syringe, One-handed performance cannot be realized aspirating contrast solution or medicinal liquid when, cause the delay of time.

Utility model content

For above-mentioned technical problem, this utility model provides a kind of one-handed performance that realizes Injector.

For solving above-mentioned technical problem, this utility model adopts the technical scheme that: carry For a kind of injector, this injector includes syringe, push rod and push handle, described injection pipe box Being located on described push rod, one end of described push rod is connected with described push handle, described syringe Be provided with finger ring in described push handle, described finger ring is used for accommodating finger, described finger ring bag Include and be positioned at the first finger ring and second finger ring of described syringe lateral symmetry distribution and be positioned at institute State the 3rd finger ring in push handle.

Alternatively, described injector also includes circular cone lock male joint, described circular cone lock male Joint includes the first port and the second port, the first described port and described syringe top Liquid outlet grafting.

Alternatively, it is provided with screw thread inside the second port of described circular cone lock male joint.

Alternatively, the other end of described push rod is connected with plug.

Alternatively, the length of the end face from the top of described plug to described 3rd finger ring is less than The length of the socket of described syringe.

Alternatively, the afterbody of described syringe is provided with the collar.

Alternatively, described syringe uses Merlon material to make and described syringe is transparent.

The syringe having the beneficial effect that injector that the injector that this utility model provides is brought There are two finger rings, push handle have a finger ring, three finger rings can penetrate three fingers, real Existing one hand control syringe to the suction of liquid with inject.Additionally, due to the afterbody of syringe It is provided with the collar, plug will not be made to deviate from syringe, it is ensured that syringe inner chamber is without ambient atmos Enter, and, when injecting medicine, when medicine will have been injected, the collar stops that push handle continues Continuing and inject forward, plug will not be completely pushed to bottom syringe, has bottom plug and syringe Appropriate safe space, will not be pushed into the gas within syringe and to be connected with liquid outlet Among other armarium, it is ensured that its safety.The liquid outlet of injector is locked by circular cone Male contact is connected with other armarium, and circular cone lock male joint has screw thread, can be with same The conduit thread lock of other armarium that injector is connected connects, it is to avoid injector Come off and the seepage of injector and other armarium junction.

Detailed description of the invention

Fig. 1 is the overall structure schematic diagram of injector, as it is shown in figure 1, circular cone lock male connects 1 is connected with syringe 2, and syringe 2 outer wall is marked with the scale of 1-12ml, and pipe Transparent, it is simple to observe, it is possible to the volume of liquid with precise control, body uses Merlon (PC) Material, material is hard, and intensity is high, it is possible to bearing enough pressure, syringe 2 is set in and pushes away On bar 4, one end of push rod 4 is connected with plug 3, the other end of push rod 4 and push handle 5 It is connected, push handle 5 is disposed with the 3rd finger ring 6 that can accommodate finger.

Fig. 2 is the structural representation of syringe, as in figure 2 it is shown, syringe have liquid outlet 7, Symmetrically arranged first finger ring 8 and second at the close collar on the collar 10 and syringe outer wall Finger ring 9, when extraction or injection liquid, can put three finger thumbs, forefinger and middle finger Enter in first finger ring the 8, second finger ring the 9, the 3rd finger ring 6, can be easily with three fingers Control the sliding stroke of push rod, singlehanded extraction or medicine injection can be realized, easy to operate.Entering When injecting of row medicine, owing to (not wrapping from the top of plug 3 to the end face of the 3rd finger ring 6 Include the 3rd finger ring) length less than the length of socket of syringe, so the most just medicine pushes away When noting complete, the collar 10 can contact with the end face of the 3rd finger ring 6, and the collar 10 stop pushes away Handle 5 continues to inject forward, and now, plug 3 leaves appropriate with the intracavity bottom of syringe Safe space, even if push handle 4 all shifts bottom onto, fits tightly with the collar 10, plug 3 Also will not fit with the intracavity bottom of syringe, it is ensured that a small amount of gas in syringe will not be from Liquid outlet 7 enters in the miscellaneous equipment being attached thereto, and then avoids the gas in syringe In entrance human body, it is ensured that the safety of operation.

Fig. 3 be the front view of circular cone lock male joint, Fig. 4 be a left side for circular cone lock male joint View, as shown in Figure 3, Figure 4, circular cone lock male joint 1 have the first port 11, Two-port netwerk 12, liquid outlet 7 grafting of the first port 11 and syringe, the second port 12 with Other armarium connects, and the second port 12 is internal has thread lock structure, it is possible to same Miscellaneous equipment thread lock that injector is connected connects, it is to avoid coming off and even of injector Connect the appearance of the Drug leakage problem at place.
