Abstract
The utility model belongs to the field of a medical instrument, relates to a cardioangiographice syringe, comprising a syringe needle, an injection pipe and a plunger, the syringe needle is mounted on and communicated with the front of the injection pipe by a syringe needle base, a loop of annular convexity for preventing the fingers from skidding is arranged at the central section of the injection pipe, an axle center pipe connected with the syringe needle base is arranged in the injection pipe, a horn mouth is arranged at the end of the axle center pipe, an axle center hole being in sliding fit with the axle center pipe and sleeved on the axle center pipe is arranged in the plunger, a sealing-plug with a kerf is arranged on the axle center hole at the end of the plunger, and a boosting finger ring is arranged at the end of the plunger by two supporting legs. The utility model has the beneficial effects the cardioangiographice syringe has simple structure and convenient use, the cordis can be sent into the blood vessel without unloading the syringe, the pushing and injecting bearing area can be increased and the pain of the palm of the medical personnel can be relieved, the syringe needle can be firmly fixed to prevent the puncture needle from shifting, and the sealing-plug can effectively prevent the blood from flowing out.
Description
(1) technical field
This utility model belongs to medical apparatus and instruments, relates to a kind of angiocardiography syringe.
(2) background technology
In the therapeutic process of cardiovascular disease, in order to understand the situation of patient's blood vessel accurately, usually contrast agent to be injected blood vessel by injector and carry out angiography, employed clinically at present contrast agent bolus device is similar with ordinary syringe, the handle of core bar is very little, add the contrast agent thickness, medical worker's lifting surface area of hands when injecting contrast agent is little like this, time slightly length will cause palm pain discomfort, syringe rocks easily during operation, thereby makes syringe needle displacement, contrast agent leaks outside, thereby influence diagnoses and treatment, also can cause injured blood vessel, cause puncture failure.Perhaps, directly thrust blood vessel or ordinary syringe is thrust blood vessel with puncture needle, remove needle tubing then and keep syringe needle, insert seal wire again in the syringe needle and send into blood vessel, like this, blood is easy to flow out when inserting seal wire, has not only lost valuable blood, and the pollution work surface, increased work difficulty to the medical worker.
(3) summary of the invention
This utility model is in order to remedy the deficiencies in the prior art, a kind of angiocardiography syringe is provided, and it can increase injects lifting surface area, alleviates medical worker's palm sense of discomfort of aching, and can fixedly secure syringe needle, avoid contrast agent to leak outside and influence diagnoses and treatment, and prevent that blood from flowing out.
This utility model is achieved by the following technical solution:
Angiocardiography syringe of the present utility model, comprise syringe needle, syringe, plunger, front end at syringe is installed by needle holder and the connection syringe needle, its special character is: the syringe middle part is provided with along excircle and prevents to point a circle annular protrusion that skids, the one axle center pipe that links to each other with needle holder is arranged in the syringe, the end of axle center pipe is a horn mouth, in plunger, have and be slidingly matched with the axle center pipe and be enclosed within axle center hole on the pipe of axle center, one sealing-plug that has a cross joint-cutting is arranged on the axle center hole of the end of plunger, also be provided with the boosting finger ring by two supporting legs at the plunger end.
Angiocardiography syringe of the present utility model is having radial blood outlet hole near on the axle center tube wall of needle holder one end.
The beneficial effects of the utility model are, this utility model is simple in structure, easy to use, do not need to unload syringe and just seal wire can be sent into blood vessel by syringe needle, can increase and inject lifting surface area, alleviate medical worker's palm sense of discomfort of aching, can fixedly secure syringe needle, prevent the puncture needle displacement, and sealing-plug can prevent effectively that blood from flowing out.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 blood outlet hole, 2 syringes, 3 plungers, 4 needle holder, 5 boosting finger rings, 6 sealing-plugs, 7 annular protrusions, 8 axle center pipe, 9 horn mouths, 10 axle center holes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Angiocardiography syringe of the present utility model, comprise syringe needle, syringe 2, plunger 3, front end at syringe 2 is installed and the connection syringe needle by needle holder 4, syringe 2 middle parts are provided with along excircle and prevent to point a circle annular protrusion 7 that skids, the one axle center pipe 8 that links to each other with needle holder 4 is arranged in the syringe, the end of axle center pipe is a horn mouth 9, in plunger 3, have and be slidingly matched with the axle center pipe and be enclosed within axle center hole 10 on the pipe of axle center, one sealing-plug 6 that has a cross joint-cutting is arranged on the axle center hole of the end of plunger, also be provided with boosting finger ring 5 by two supporting legs at the plunger end.Near on the axle center tube wall of needle holder one end radial blood outlet hole 1 is being arranged.The cross joint-cutting of sealing-plug is similar to the existing vertical cross joint-cutting of cross bore nipple.
Angiocardiography syringe of the present utility model when carrying out angiography, thrusts blood vessel with syringe needle, and needle handle 7 invests on the skin.Outwards drag plunger 3 by boosting finger ring 5,, illustrate that syringe needle has inserted blood vessel if there is blood to enter syringe by blood outlet hole 1.The sealing-plug 6 that has the cross joint-cutting is convenient to insert seal wire and is prevented that blood from flowing out, and seal wire is managed 8 ends from the axle center horn mouth inserts, and sends into blood vessel through needle holder and syringe needle, finishes the action of delivery guidewire.
Claims (2)
1. angiocardiography syringe, comprise syringe needle, syringe, plunger, front end at syringe is installed by needle holder and the connection syringe needle, it is characterized in that: the syringe middle part is provided with along excircle and prevents to point a circle annular protrusion that skids, the one axle center pipe that links to each other with needle holder is arranged in the syringe, the end of axle center pipe is a horn mouth, in plunger, have and be slidingly matched with the axle center pipe and be enclosed within axle center hole on the pipe of axle center, one sealing-plug that has a cross joint-cutting is arranged on the axle center hole of the end of plunger, also be provided with the boosting finger ring by two supporting legs at the plunger end.
