Abstract
The utility model discloses a kind of cardio angiographic unfolder, it is provided with piston in injection tube, the rear side of piston is provided with push rod, it is characterized in that: the inner magnetic sleeve being provided with an annular in injection tube, be equipped with an outer magnetic sleeve outside injection tube, outer magnetic sleeve and inner magnetic sleeve can along the axial synchronous slides of injection tube by magnetic attraction effect; Described piston nose is provided with the round platform protruded forward, and this round platform can insert in the endoporus of inner magnetic sleeve.Its structure is simple, convenient to use, can ensure that contrast agent is even, ensure contrasting effects in long bolus infusion processes.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of cardio angiographic unfolder.
Background technology
Angiocardiography is a kind of the most frequently used method of Diagnosis and Treat cardiovascular disease.Clinical usual employing syringe is injected, and due to contrast agent often comparatively thickness, other medicaments can be adopted to carry out diluting rear injection, time longer upon injection, contrast agent is skewness in syringe, and common syringe does not stir the function that is mixed, and then affects contrasting effects.
Utility model content
For overcoming above-mentioned technical problem, it is simple that this utility model provides a kind of structure, easy to operate, in contrast agent bolus process, can carry out the cardio angiographic unfolder stirred.
For realizing above-mentioned technical purpose, this utility model is by the following technical solutions: a kind of cardio angiographic unfolder, comprise injection tube, piston is provided with in injection tube, the rear side of piston is provided with push rod, it is characterized in that: the inner magnetic sleeve being provided with an annular in injection tube, be equipped with an outer magnetic sleeve outside injection tube, outer magnetic sleeve and inner magnetic sleeve can along the axial synchronous slides of injection tube by magnetic attraction effect; Described piston nose is provided with the round platform protruded forward, and this round platform can insert in the endoporus of inner magnetic sleeve.
This utility model has following beneficial effect: in contrast agent bolus process, outer magnetic sleeve can be utilized to move in injection tube to drive inner magnetic sleeve, play certain stirring action, avoid skewness to contrast agent; At the end of injecting, the round platform in piston front enters in the endoporus of inner magnetic sleeve, avoids contrast agent too much residual in injection tube.Its structure is simple, convenient to use, can ensure that contrast agent is even, ensure contrasting effects in long bolus infusion processes.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is the structural representation at the end of contrast agent bolus.
In figure, 1, injection tube, 2, inner magnetic sleeve, 3, outer magnetic sleeve, 4, round platform, 5, piston, 6, push rod, 7, endoporus.
Detailed description of the invention
Shown in Fig. 1,2, a kind of cardio angiographic unfolder disclosed in this utility model, it comprises injection tube 1, piston 5 is provided with in injection tube 1, the rear side of piston 5 is provided with push rod 6, it is characterized in that: the inner magnetic sleeve 2 being provided with an annular in injection tube 1, be equipped with an outer magnetic sleeve 3 outside injection tube 1, outer magnetic sleeve 3 and inner magnetic sleeve 2 can along the axial synchronous slides of injection tube 1 by magnetic attraction effect; Described piston 5 front end is provided with the round platform 4 protruded forward, and this round platform 4 can insert in the endoporus 7 of inner magnetic sleeve 2.
In contrast agent bolus process, outer magnetic sleeve 3 can be utilized to drive inner magnetic sleeve 2 mobile in injection tube 1, certain stirring action is played to contrast agent, avoids skewness; At the end of injecting, the round platform 4 in piston 5 front enters in the endoporus 7 of inner magnetic sleeve 2, avoids contrast agent too much residual in injection tube 1.Its structure is simple, convenient to use, can ensure that contrast agent is even, ensure contrasting effects in long bolus infusion processes.
