Abstract

The utility model discloses an angiocardiography injector which comprises an injector and a needle, wherein the injector is internally provided with a piston; a push rod is connected onto the piston; a ring-shaped baffle is arranged on the outer wall of the injector along the circumferential direction; a push-pull ring is arranged at the tail end of the push rod; furthermore, the injector and the needle are connected through a hose; and a holding part is arranged on the part, adjacent to the needle, of the hose. The angiocardiography injector is simple in structure and convenient in use; and during the use of medical personnel, the phenomena of stress and pain do not occur, so that the stability of the angiocardiography injector can be ensured.

Description

The angiocardiography injector

Technical field

This utility model relates to the medical instruments technical field, relates in particular to a kind of angiocardiography injector.

Background technology

In the therapeutic process of cardiovascular disease,, usually to contrast agent be injected human vas and carry out angiography in order to understand the situation of patient's blood vessel exactly; The used apparatus of this process promptly is an injector, and employed clinically at present injector is compared with common syringe, and its volume is little; Add that contrast agent itself has higher viscosity; So the medical worker often need use bigger power when injecting contrast agent, and because the contact area of injector and hands is less, easy palm to the medical worker causes compressing pain after injecting for a long time; Influence medical worker's manipulation accuracy; In case syringe and syringe needle shake, cause contrast agent to leak outside easily, influence diagnoses and treatment.

The utility model content

This utility model technical problem to be solved is: a kind of angiocardiography injector is provided, can produce compressing pain to medical worker's hands in use.

For solving the problems of the technologies described above; The technical scheme of this utility model is: the angiocardiography injector; Comprise syringe and syringe needle, be provided with piston in the said syringe, be connected with push rod on the said piston; Its circumferencial direction of outer wall upper edge of said syringe is provided with ring baffle, and the end of said push rod is provided with the push-and-pull ring.

Preferably, said syringe and syringe needle are through hose connection, and the position near said syringe needle on the said flexible pipe is provided with the portion of gripping.

After having adopted technique scheme; The beneficial effect of this utility model is: owing on its circumferencial direction of the outer wall upper edge of syringe, be provided with ring baffle, and the end of push rod also is provided with the push-and-pull ring, and then the medical worker can withhold forefinger and middle finger on said ring baffle when injecting contrast agent; Thumb inserts in the said push-and-pull ring simultaneously; Like this, not only strengthened the contact area of injector and hands, and it is more reliable and more stable to operate; No matter be to promote push rod or pulling push rod this moment, can not cause compressing pain to medical worker's hands.

Because syringe and syringe needle are through together hose connection, the position near syringe needle on flexible pipe is provided with the portion of gripping, and then the medical worker is when injecting; Can one hand-held syringe, one hand-heldly grips portion, waits when syringe needle thrust human body; No matter how syringe rocks; As long as the medical worker stably holds the portion of gripping, syringe needle just can not shake, and guarantees that contrast agent can not leak outside.

Description of drawings

Below in conjunction with accompanying drawing and embodiment this utility model is described further:

Accompanying drawing is the structural representation of this utility model embodiment;

Among the figure: 1. syringe needle; 2. grip portion; 3. flexible pipe; 4. syringe; 5. piston; 6. ring baffle; 7. push rod; 8. push-and-pull ring.

The specific embodiment

Shown in accompanying drawing, be a kind of embodiment of angiocardiography injector, this injector comprises syringe 4; The inside of said syringe 4 is provided with piston 5, is connected with push rod 7 on the said piston 5, is connected with syringe needle 1 at the front end of said syringe 4 through flexible pipe 3; Simultaneously be provided with the portion of gripping 2 near the position of said syringe needle 1 at said flexible pipe 3, like this, when the medical worker carries out contrast agent bolus to patient; Can hand the said portions 2 that grip by a hand-held syringe 4,, no matter how said syringe 4 rocks; Said syringe needle 1 can both keep stable in patient's body, avoid contrast agent to leak outside.

Its circumferencial direction of outer wall upper edge of said syringe 4 is provided with ring baffle 6, and the end at said push rod 7 is provided with push-and-pull ring 8 simultaneously, when the medical worker injects contrast agent; Can forefinger and middle finger be withheld on said ring baffle 6, thumb inserts in the said push-and-pull ring 8, so then; Not only strengthened the contact area of injector and hands; And it is more reliable and more stable to operate, and no matter be to promote said push rod 7 or pulling push rod 7 this moment, can not cause compressing pain to medical worker's hands.

This angiocardiography injector is simple in structure, easy to use, and the medical worker can not produce the phenomenon of compressing pain in use, thereby can guarantee the stability of contrast agent bolus.

This utility model is not limited to the above-mentioned specific embodiment, and all are based on the technical conceive of this utility model, and the structural improvement of having done all falls among the protection domain of this utility model.

Claims

1. the angiocardiography injector comprises syringe and syringe needle, is provided with piston in the said syringe, is connected with push rod on the said piston, it is characterized in that: its circumferencial direction of outer wall upper edge of said syringe is provided with ring baffle, and the end of said push rod is provided with the push-and-pull ring.

2. angiocardiography injector as claimed in claim 1 is characterized in that: said syringe and syringe needle are through hose connection, and the position near said syringe needle on the said flexible pipe is provided with the portion of gripping.
