Description
Technical field
This utility model relates to a kind of assist device of syringe, belongs to technical field of medical appliance structures.
Background technology
At present, when the conduit arterial chemotherapy Embolization (TACE) of passing through is injected iodized oil with microtubular, because of the microtubular diameter is 2.5-3.0F (0.83-1mm), thin and the iodized oil thickness of internal diameter, therefore using ordinary syringe injects iodized oil and requires great effort very much, increase the operation technique difficulty, and can not control the speed that iodized oil is injected, increase operation risk.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, provide a kind of reasonable in design, simple installation, sterilization convenient, durable, reusable, and can be used with existing syringe, may command is injected the syrings driver of speed.
This utility model is to realize by the following technical programs:
A kind of assist device of syringe, its special character is to comprise that pipe fitting 1 and part are rotatably connected in the push rod 2 in the pipe fitting 1, the inwall of pipe fitting 1 is provided with female thread, the bar wall of push rod 2 is provided with the external screw thread that uses with the screw-internal thread fit of pipe fitting 1, by rotation push rod 2, can make push rod 2 advance or fall back along pipe fitting 1 inwall, the mouth of pipe place of pipe fitting 1 is connected with and is used for block 3 that itself and syringe jacket pipe 4 are connected together; Because it is pipe fitting 1 and push rod 2 adopts helicitic textures, therefore not only laborsaving but also be convenient to control and inject speed;
Described block 3 is barrel-shaped, the bottom offers the opening 8 that is used to insert syringe jacket pipe 4, the diameter of opening 8 is greater than the diameter of syringe jacket pipe 4 and less than the diameter of syringe jacket pipe 4 afterbody syringe jacket crimpings 7, block 3 can be fixed as one syringe jacket pipe 4 and pipe fitting 1;
The inwall of described block 3 is provided with female thread, and the outer wall of pipe fitting 1 is provided with the external screw thread that uses with block 3 screw-internal thread fit;
Use for convenience, the afterbody of described push rod 2 is provided with the bar shaped handle 6 of length greater than pipe fitting 1 diameter;
The assist device of described syringe is to be made by metal material, and sterilization is convenient.
This utility model reasonable in design according to the laborsaving principle of spiral, can promote injection rod easily, has reduced the difficulty of operation technique, is convenient to the control speed of injecting simultaneously and improves operation safety, has sterilize convenient, low, the reusable advantage of cost.
