Abstract
The utility model discloses a cardiovascular intervention injector. The cardiovascular intervention injector comprises a needle tube, wherein a joint is arranged at one end of the needle tube, a blocking sheet is arranged at the end part of the needle tube, a piston rod is arranged in the needle tube, a piston is arranged at one end of the piston rod, a push head is arranged at the other end of the piston rod, a fixed ring is fixedly arranged on the blocking sheet, a bolt is in threaded connection with the fixed ring, a screw cap is arranged in the fixed ring, and the thread matched with the screw cap is arranged on the piston rod. When the cardiovascular intervention injector works, after the push head is rotated, the piston rod rotates, the piston is pushed to advance or retreat, the cardiovascular intervention injector can be held conveniently by medical staff due to the arrangement of a holding ring, and the piston which advances in a spiral manner can reduce the labor intensity of the medical staff.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of cardiovascular interventional injector.
Background technology
At present, when to patient, carrying out cardio-vascular interventional therapeutic, mostly adopt syringe to inject medium clinically, owing to getting involved slightly thickness of medium, operate so very complicated, waste time and energy, to medical personnel, increased great work difficulty.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency for technique scheme, when offering patient and carrying out cardio-vascular interventional therapeutic, and time saving and energy saving a kind of cardiovascular interventional injector.
Addressing the above problem the technical solution of the utility model is:
A kind of cardiovascular interventional injector, comprise needle tubing, an end on described needle tubing has joint, and the end of needle tubing has catch, is provided with piston rod in needle tubing, one end of piston rod is provided with piston, the other end is provided with cuts somebody's hair, and on described catch, is fixed with ring for fixing, and bolt has been threaded on described ring for fixing, be provided with nut in described ring for fixing, there is the screw thread matched with nut on described piston rod.
Below to further improvement in the technical proposal:
Described needle tubing is socketed with outward holds ring, and described holding on ring has groove.
Described distance of holding between ring and catch is 10.5 millimeters.
During work, rotation is cut somebody's hair, and piston rod rotates, and promotes piston-advance or retreats, hold ring the setting party medical personnel's assurance, the piston that spiral advances has reduced medical personnel's labor intensity.
Below in conjunction with drawings and Examples, technique scheme is described further.
The accompanying drawing explanation
The structural representation that accompanying drawing 1 is a kind of cardiovascular interventional injector in this utility model embodiment;
The structural representation of accompanying drawing 2 for cutting somebody's hair.
In figure:
The 1-needle tubing; The 2-joint; The 3-piston; The 4-piston rod; 5-holds ring; The 6-groove; The 7-catch; The 8-ring for fixing; The 9-bolt; The 10-nut; 11-cuts somebody's hair.
The specific embodiment
Embodiment, as shown in Figures 1 and 2, a kind of cardiovascular interventional injector, comprise needle tubing 1, an end on described needle tubing 1 has joint 2, and the end of needle tubing 1 has catch 7, is provided with piston rod 4 in needle tubing 1, one end of piston rod 4 is provided with piston 3, the other end is provided with cuts somebody's hair 11, on described catch 7, is fixed with ring for fixing 8, and bolt 9 has been threaded on described ring for fixing 8, be provided with nut 10 in described ring for fixing 8, on described piston rod 4, there is the screw thread matched with nut 10; Outer being socketed with of described needle tubing 1 held ring 5, and described holding on ring 5 has groove 6; Described hold ring 5 and 7 of catch apart from being 10.5 millimeters; Cut somebody's hair 11 cross section is cross.
During work, rotate and to cut somebody's hair 11, piston rod 4 rotates, and promotes piston 3 and advances or retreat, hold ring 5 the setting party medical personnel's assurance, the piston 3 that spiral advances has reduced medical personnel's labor intensity.
