Abstract
The utility model discloses a kind of heart opacifying injection utensil, comprise syringe needle position, 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, and the other end is connected with needle handle, described syringe one end is connected with syringe needle, there is the screw hole supporting with lead screw one end, and lead screw passes from screw hole, and described syringe needle position is also provided with controlled valve, described syringe, near needle handle one end, is also provided with tread plate outside syringe.The beneficial effects of the utility model are: reduce contrast-medium injection difficulty, conveniently control injection speed, improve the work efficiency of medical personnel, improve the comfort level of operator, reduce medical-risk.
Description
Technical field
This utility model belongs to a kind of instrument used for injection, particularly a kind of heart opacifying injection utensil.
Background technology
Heart radiography has coronarography and heart (atrium, ventricle) radiography.Coronary angiography is exactly prolong along the artificial entrance of radial artery (wrist place) or femoral artery (thigh place) the coronary ostium place that row arrives heart with a thin conduit as hair, then contrast agent (developing under X-ray) is injected coronary artery, the form of such coronary artery inside just can show, such as see that arteria coronaria has and do not have narrow, speckle etc., but substantially do not check by this and understand cardiac shape, the main or blood flow rate understood in the external morphology of arteria coronaria and arteria coronaria.Angiography, during application large bolus injection, has its toxic action of multifactor impact perhaps.During angiocardiography, fast injection increases several times than danger poisoning when slowly injecting, and master oozes effect due to the height of contrast agent, and due to radiography collection thickness, the syringe therefore used clinically promotes to compare 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 opacifying injection utensil.
The technical solution of the utility model is: a kind of heart opacifying injection utensil, comprise syringe needle position, 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, described syringe one end is connected with syringe needle, there is the screw hole supporting with lead screw one end, lead screw passes from screw hole, screw is used to promote injection, for thickness, and have the injection of the heart contrast agent of pressure, this design improves the pattern of traditional flat promoting drug greatly, can be laborsaving, again can control rate stably, it is significant improvement.
Described syringe needle position is also provided with controlled valve, and described syringe, near needle handle one end, is also provided with tread plate outside syringe.The use of controlled valve, ensure that in case of high pressures, and syringe does not produce the phenomenon fallen back, thus reduces medical-risk.
Described needle handle can be string configuration.The common circular configuration of such structural rate is more convenient for finger grip firmly, and twisting needle handle of conveniently having an effect, thus drives shank driven forward piston, is injected in vivo by contrast agent.
The thickness of described needle handle can be 0.8 ~ 1.8cm, and the needle handle crossed wider than residence is all not easy to finger grip and has an effect, and preferred thickness is 1.2cm.
The material being also provided with tread plate outside described syringe is preferably latex, can increasing friction force, is convenient to firmly, can improve again the comfort level with contact skin.
The material of described lead screw is metal, due to contrast agent thickness, is difficult to promote, adopts the lead screw of metal material to compare than the pintle of ordinary syringe plastic material, difficult deformation, stressed also even, more can ensure the uniform velocity of contrast-medium injection.
The material of described lead screw is preferably rustless steel, is convenient to disinfecting when producing, and prevents from getting rusty before use, thus bring medical-risk.
The beneficial effects of the utility model are: reduce contrast-medium injection difficulty, conveniently control injection speed, improve the work efficiency of medical personnel, improve the comfort level of operator, reduce medical-risk.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further:
As shown in drawings, a kind of heart opacifying injection utensil, comprise syringe needle position 8, syringe 2 and pintle, it is characterized in that: pintle comprises piston 3, lead screw 4 and needle handle 5, described lead screw 4 one end is connected with piston 3, the other end is connected with needle handle 6, described syringe 2 one end is connected with syringe needle position 8, 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 string configuration, thickness is 1.2cm, the material of lead screw 4 is stainless steel, described syringe needle position 8 is also provided with controlled valve 1, described syringe 2 is near needle handle 6 one end, tread plate 7 is also provided with outside syringe 2, the material of tread plate 7 is latex.
During use, after opening controlled valve 1, left hand refers to pinch tread plate 7, and the right hand refers to slowly rotate needle handle 6, drive lead screw 4 to move forward, thus piston 3 promotes contrast agent is injected in vivo, and then shuts controlled valve 1.
The beneficial effects of the utility model are: reduce contrast-medium injection difficulty, conveniently control injection speed, improve the work efficiency of medical personnel, improve the comfort level of operator, reduce medical-risk.
