Description
Technical field
This utility model relates to a kind of technical field of medical instrument, specifically a kind of injector for medical purpose.
Background technology
Syringe is a kind of common medical instruments, is generally made up of syringe needle, syringe and the piston rod that matches, and it uses widely in medical and health industry.Traditional syringe is in use; the distance punctured can not be controlled; namely the internal distance of needle point leading portion insertion of syringe needle cannot be determined; complete in experience and range estimation; puncture apart from the too short or long therapeutic effect that all can have influence on patient, it is also possible to make some normal structures receive injury, for instance neural or skeleton sustains damage; so needing paracentesis depth is done to limit accurately, the health of protection patient.
Summary of the invention
This utility model is a kind of simple and reasonable for structure in order to overcome drawbacks described above to provide, and can control paracentesis depth, facilitate the syringe of puncture procedure.
The technical solution adopted in the utility model is: a kind of injector for medical purpose, including syringe needle, syringe and piston rod, syringe needle is detachably connected to syringe front end, it is characterized in that: also include controlling set and cap stopper, described control set is placed on outside syringe needle, control set and include fixed sleeving and moving casing, fixed sleeving and moving casing are all in hollow tubular structures, fixed sleeving is tightly placed in the outside of syringe needle hypomere, moving casing is arranged on the outside of the epimere of fixed sleeving, moving casing and fixed sleeving are threaded connection, and can move up and down along fixed sleeving, the front end of moving casing is provided with cap stopper, cap stopper is detachable connection with moving casing.
As a kind of preferred structure of the present utility model, described fixed sleeving bottom endoporus is bellmouth, and this bellmouth is corresponding to the tapered needle seat of syringe needle hypomere, and fixed sleeving is by this bellmouth and the tight grafting of syringe needle.
As this utility model another kind preferred structure, described piston rod outer end is provided with prolonging handle, and prolonging handle is Long Circle platy structure, and prolonging handle is vertical with piston rod axis.
This utility model is the control set that is made up of fixed sleeving and moving casing in syringe needle arranged outside, fixed sleeving is fixing for being connected with syringe needle, can the position of up-down adjustment moving casing by rotating moving casing, so just can regulate needle point and expose the length of moving casing, thus controlling the degree of depth of puncture.This utility model is also provided with prolonging handle in piston rod outer end, facilitates the operation to piston push-and-pull when injecting.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
In conjunction with accompanying drawing, this utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, a kind of injector for medical purpose, including syringe needle, syringe 2 and piston rod 3, syringe needle is detachably connected to syringe 2 front end, this utility model also includes controlling set and cap stopper 1, described control set is placed on outside syringe needle, control set and include fixed sleeving 4 and moving casing 5, fixed sleeving 4 and moving casing 5 are all in hollow tubular structures, fixed sleeving 4 is tightly placed in the outside of syringe needle hypomere, moving casing 5 is arranged on the outside of the epimere of fixed sleeving 4, moving casing 5 and fixed sleeving 4 are threaded connection, and can move up and down along fixed sleeving 4, the front end of moving casing 5 is provided with cap stopper 1, cap stopper 1 is connected for detachable with moving casing 5, cap stopper 1 inserts the needle point that can protect syringe needle in the hole of moving casing 5 front end, can also be dust-proof, take away cap stopper 1, rotary moveable sleeve pipe 5, moving casing 5 can be made to move up and down along fixed sleeving 4, when moving casing 5 moves down more, the distance that needle point just exposes is longer, thus the degree of depth punctured can be regulated according to needs of patients.
As a kind of preferred structure of the present utility model, described fixed sleeving 4 bottom endoporus is bellmouth, and this bellmouth is corresponding to the tapered needle seat 6 of syringe needle hypomere, and fixed sleeving 4 is by this bellmouth and the tight grafting of syringe needle.Fixed sleeving 4 and moving casing 5 are made typically by transparent rubber or plastics, and having certain elasticity can tightly be enclosed within outside syringe needle, are also convenient for observing and sterilization.Described piston rod 3 outer end is provided with prolonging handle 7, and prolonging handle 7 is in Long Circle platy structure, and prolonging handle 7 is vertical with piston rod 3 axis.
This utility model carries out injecting or puncturing by regulating needle point exposed length accurately, facilitates patient to play little pin, also facilitates injecting insulin for diabetic patients.The handle of piston rod 3 rear end has been extended by this utility model, during use more smoothly and accurately.
This utility model has simple and reasonable for structure, can control paracentesis depth, facilitates the feature of puncture procedure.
