Abstract

An angiocardiography injector belongs to the technical field of medical apparatus and has the technical scheme that the injector includes a pinhead, an injection tube, a piston and a mandrel. The angiocardiography injector is characterized in that the tail end of the mandrel is fixedly provided with a ring; a fixing wing is fixedly arranged on the pinhead. The angiocardiography injector has simple structure, is convenient for use, can enlarge the stressed area of bolus injection when angiocardiography is carried out, lighten the uncomforting feeling of ache palm of the medical staff as well as can firmly fix the injection tube to avoid a contrast media leaking to affect the diagnosis and treatment.

Description

The angiocardiography injector

Technical field:

This utility model belongs to technical field of medical instruments, is a kind of angiocardiography injector specifically.

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 make the syringe needle displacement, contrast agent leaks outside, thereby influences diagnoses and treatment.

Summary of the invention:

The purpose of this utility model provides a kind of when carrying out angiography, can increase and inject lifting surface area, alleviates medical worker's palm sense of discomfort of aching, and can fixedly secure syringe needle, avoids contrast agent to leak outside and influences the angiocardiography injector of diagnoses and treatment.

The technical solution of the utility model is: comprise syringe needle, syringe, piston and core bar, it is characterized in that being fixed with finger ring at the core bar end, be fixed with fixed-wing on the syringe needle.

The beneficial effects of the utility model are: this utility model is simple in structure, and is easy to use, when carrying out angiography, can increase and inject lifting surface area, alleviate 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.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

Among the figure 1, syringe needle, 2, syringe, 3, piston, 4, core bar, 5, finger ring, 6, fixed-wing.

The specific embodiment:

Comprise syringe needle 1, syringe 2, piston 3 and core bar 4, it is characterized in that being fixed with finger ring 5, be fixed with fixed-wing 6 on the syringe needle 1 at core bar 4 ends.When carrying out angiography, syringe needle 1 is thrust blood vessel, fixed-wing 6 invests on the skin, and thumb pierces into to inject in the finger ring 5 and gets final product.

Claims (1)

1, angiocardiography injector comprises syringe needle (1), syringe (2), piston (3) and core bar (4), it is characterized in that: be fixed with finger ring (5) at core bar (4) end, be fixed with fixed-wing (6) on the syringe needle (1).
