Abstract
The utility model provides a precession type pressure syringe, the structure is composed of a tube shell, an ordinary syringe needle tube, a tube shell upper cover, a screw cap, a screw and a positioning ring, the ordinary syringe needle tube is fixed in the tube shell by the tube shell upper cover and the positioning ring, the lower end of the screw cap is fixed at the upper part of the tube shell upper cover by a thread, the screw is connected with the middle of the screw cap by the thread, the lower end of the screw is extended in the ordinary syringe needle tube and is connected with an injection rubber plug. Compared with the prior art, the precession type pressure syringe has reasonable design, simple structure, easy processing, convenient usage, easy operation, smooth and easy control of the injection speed and so on, so the utility model has very high popularization and using values.
Description
1, technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of screw type pressure injector.
2, technical background
In the clinical treatment of hospital, the method material that some viscosity are bigger that usually adopts injection to fill is expelled to certain position of human body, the in use existing deficiency of the syringe of prior art is because common various injector for medical purpose are just injected water quality or the lower medicine of viscosity, if the big user of viscosity will very big strength just can be finished filling injection, and the very difficult control of the operational stability of the speed of injection and injection, thereby plastic injection quality and therapeutic effect have been influenced.
3, summary of the invention
The purpose of this utility model provides a kind of screw type pressure injector that can be used for the injection of high viscosity medicine.
The purpose of this utility model realizes in the following manner, the needle tubing of ordinary syringe is placed among the Can, top at shell is provided with sctew feeder, by injection plug in the screw rod promotion ordinary syringe of sctew feeder the high viscosity medicine is injected the position that human body need be filled.
Accompanying drawing is the structural representation of screw type pressure injector.
4, description of drawings
With reference to accompanying drawing to explaining below the precessing pressure syringe Zuo of the present utility model.
Precessing pressure syringe of the present utility model, as shown in drawings, its structure is You shell 9, general Logical syringe needle tube 6, shell loam cake 11, nut 3, screw rod 2 and locating ring 4 consist of ordinary syringe Zhen pipe 6 is fixed on shell 9 Zhi Zhong by shell loam cake 11 and locating ring 4, and screw thread is passed through in the lower end of nut 3 Be fixed on the top of shell loam cake 11, screw rod 2 joins by screw thread Yu between nut 3 Zhong, screw rod 2 lower End extends ordinary syringe Zhen and manages 6 Zhi Zhong Yu injection piston 7 joins.
The upper end of the top of Zai shell 9 and screw rod 2 is respectively arranged with operating grip 1,5, Zai shell 9 The lower end has the Yuan hole 12 of stretching out for ordinary syringe needle hub 8, also has on the outer wall of Zai shell 9 Observation window 10.
5, embodiment
Its processing and fabricating of screw type pressure injector of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.The ordinary syringe needle tubing is general disposable syringe needle tubing, and other parts can adopt the metal process for machining to make, and also can adopt the engineering plastics injection moulding to make.
The use of screw type pressure injector of the present utility model is also very simple and convenient, during use the needle tubing of common disposable syringe is placed among the shell, with shell loam cake and locating ring its upper end is pressed abd fixed among the shell then, again nut is screwed in by screw thread with the shell loam cake, screw rod is screwed in the middle of nut by screw thread, injection plug in its lower end and the disposable syringe is fixed together,, the turn screw rod both can drive plug and move up and down in syringe needle tube.Rotate by handle turn screw rod when injection is used and promote the injection plug and move down the high viscosity medicine in the needle tubing is injected out outside the needle tubing.
Screw type pressure injector of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, easy to operate and injection speed easy to use be steadily easy to control, thereby, have good value for applications.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
