Abstract
The utility model discloses a kind of heart contrast injector, comprise syringe needle, syringe and pintle, it is characterized in that: pintle comprises piston, lead screw and needle handle, described lead screw one end is connected with piston, the other end is connected with needle handle line, described syringe one end is connected with syringe needle, and there is the screw hole supporting with lead screw one end, and lead screw passes from screw hole.The beneficial effects of the utility model are: reduce contrast-medium injection difficulty, the convenient injection speed of controlling, improves medical personnel's work efficiency, reduces medical-risk.
Description
Technical field
This utility model belongs to a kind of syringe, particularly a kind of heart contrast injector.
Background technology
Heart radiography has coronarography and heart (atrium, ventricle) radiography.Coronary angiography is exactly along the artificial entrance of radial artery (wrist place) or femoral artery (thigh place), to prolong the coronary ostium place that row arrives heart with a thin as conduit for hair, then contrast agent (developing) is injected to coronary artery under X-ray, the form of coronary artery inside just can show like this, such as seeing that arteria coronaria has and there is no narrow, speckle etc., but substantially can not check to understand cardiac shape by this, mainly still understand the external morphology of arteria coronaria and the blood flow rate in arteria coronaria.Angiography, during application large bolus injection, has its toxic action of multifactor impact perhaps.During angiocardiography, fast injection during than slow injection poisoning danger increase several times, master is that the height due to contrast agent oozes effect, due to radiography collection thickness, the syringe therefore using clinically promotes relatively effort, and is difficult to grasp suitable speed.
Summary of the invention
This utility model belongs to a kind of syringe, particularly a kind of heart contrast injector.
The technical solution of the utility model is: a kind of heart contrast injector, comprise syringe needle, syringe and pintle, it is characterized in that: pintle comprises piston, lead screw and needle handle, described lead screw one end is connected with piston, the other end is connected with needle handle line, described syringe one end is connected with syringe needle, and there is the screw hole supporting with lead screw one end, and lead screw passes from screw hole., use screw to promote injection, for thickness, and there is the injection of the heart contrast agent of pressure, this design has improved the pattern of traditional flat promoting drug greatly, can be laborsaving, control rate stably, is significant improvement again.
Described needle handle can be strip structure.Such structure is more firm than the common circular configuration finger grip of being more convenient for, and the twisting needle handle of conveniently having an effect, thereby drives shank to promote forward piston, and contrast agent is injected in vivo.
The thickness of described needle handle can be 0.8～1.8cm, and the wide needle handle of crossing residence is all not easy to finger grip and has an effect, and preferred thickness is 1.2cm.
The material of described lead screw is metal, due to contrast agent thickness, is difficult to promote, and adopts the lead screw of metal material to compare than the pintle of ordinary syringe plastic material, and difficult deformation is stressed also even, more can guarantee the uniform velocity of contrast-medium injection.
The material of described lead screw is preferably rustless steel, disinfecting while being convenient to produce, and prevent from getting rusty before use, thereby bring medical-risk.
The beneficial effects of the utility model are: reduce contrast-medium injection difficulty, the convenient injection speed of controlling, improves medical personnel's work efficiency, reduces medical-risk.
Accompanying drawing explanation
Accompanying drawing is surface structure schematic diagram of the present utility model.
In figure 1, syringe needle, 2, syringe, 3, piston, 4, lead screw, 5, screw hole, 6, needle handle
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described further:
As shown in drawings, a heart contrast injector, comprises syringe needle 1, syringe 2 and pintle, it is characterized in that: pintle comprises piston 3, lead screw 4 and needle handle 6, described lead screw 4 one end are connected with piston 3, the other end is connected with needle handle 6, and described syringe 2 one end are connected with syringe needle 1, and there is the screw hole 5 supporting with lead screw 4 one end, lead screw 4 passes from screw hole 5, needle handle 6 is strip structure, and thickness is 1.2cm, and the material of lead screw 4 is stainless steel.
During use, with finger, pinch, and slowly rotate needle handle 6, drive lead screw 4 to move forward, thereby piston 3 promotes contrast agent, be injected in vivo.
The beneficial effects of the utility model are: reduce contrast-medium injection difficulty, the convenient injection speed of controlling, improves medical personnel's work efficiency, reduces medical-risk.
