Abstract
The utility model relates to a medical appliance, particularly a syringe, which is provided with a syringe needle, a syringe needle seat, a syringe tube, a piston and a push-pull rod, wherein the syringe needle is fixed at the front end of the syringe needle seat, the front end of the syringe tube is provided with a connected opening of the syringe needle seat, and the syringe needle seat is fixed on the connected opening of the syringe needle seat on the front of the syringe tube; the piston is arranged in the syringe tube, and the push-pull rod is fixed on the piston; the rear end of the syringe needle is provided with an outlet, a liquid medicine sleeve is arranged in the outlet, and the open end of the liquid medicine sleeve is hermetically fixed with the outlet of the syringe needle seat. The utility model has the advantages of novel and reasonable structure design, convenient installation and operation, shapely configuration and easy operation. When the utility model is used, the liquid medicine is pumped in the syringe tube and is not directly contacted with the inner wall of the syringe tube, and the syringe tube, the piston, and the push-pull rod can be reused for a long time.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of syringe.
Background technology
People need carry out Drug therapy when sick, modal is to have an injection.When having an injection, syringe is after using once, and the inner chamber of the overcoat of syringe can contact with liquid medicine, for fear of cross infection, if will reuse, just tackle syringe itself and carry out disinfection, and disinfecting process is more numerous and diverse.What generally use when having an injection at present is disposable sterilized injector, and this syringe major part is made of plastics, and cost is low, and it is discarded to be about to whole syringe after having beaten, and disposable sterilized injector can not be recycled because of remaining liquid medicine is arranged, can only be with it buried or burn.It is estimated that China 1 year needs with 15,000,000,000 above disposable sterilized injectors, so much amount syringes discarded is the great waste to the energy, not only inconvenience but also take manually during processing, and the while has also been caused great pollution to environment.
Technical scheme
The purpose of this utility model is that a kind of medical and health standard that can reach of proposition again can reusable environment-protecting type aseptic injector.
The purpose of this utility model is achieved in that environment-protecting type aseptic injector, have cone, overcoat and core bar, the front end of core bar is provided with piston, piston is arranged in the overcoat, and the overcoat front end has the cone holder, and cone is fixed on the cone holder, cone front end fixed needle, the cone rear end has counterbore, is provided with the liquid medicine cover in the counterbore, the opening of liquid medicine cover and the counterbore end sealing and fixing of cone.
In most preferred embodiment of the present utility model:
Also be fixed with spring before the described piston, the buffer substrate tablet of being made by the silica gel sheet is set before the spring.
The inwall of described cone holder has identical tapering with the outer wall of cone, and all dwindles to the core bar direction from syringe needle, and tapering is 6: 100, and cone closely is fixed in the cone holder.
The opening that the described liquid medicine of being made by rubber finger sleeve overlaps is enclosed within the counterbore end of cone.
The utility model has the advantages that structural design is new reasonable, easy to install, elegant in appearance, easy and simple to handle, liquid medicine is drawn in the syringe and does not directly contact with the syringe inwall when having an injection, thereby syringe, piston and push-pull bar are reused for a long time.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of environment-protecting type aseptic injector as shown in Figure 1, have cone 1, overcoat 2 and core bar 3, the front end of core bar 3 is provided with piston 4, piston 4 is arranged in the overcoat 2, and overcoat 2 front ends have cone holder 21, and cone 1 is fixed on the cone holder 21, cone 1 front end fixed needle 11, cone 1 rear end has counterbore 12, is provided with liquid medicine cover 5 in the counterbore 12, the opening of liquid medicine cover 5 and the counterbore 12 end sealing and fixing of cone 1.Also be fixed with spring 6 before the piston 4, buffer substrate tablet 7 is set before the spring 6.The inwall of cone holder 21 has identical tapering with the outer wall of cone 1, and all dwindles to the core bar direction from syringe needle, and cone 1 closely is fixed in the cone holder 21.Liquid medicine cover 5 is rubber finger sleeves.Buffer substrate tablet 7 is silica gel sheets.The opening of liquid medicine cover 5 is enclosed within counterbore 12 ends of cone 1.
The glass syringe that environment-protecting type aseptic injector external form and tradition are used is basic identical, overcoat and core bar are made by hard glass.Cone is made with polyethylene by annotating.The characteristics of this utility model maximum are on this cone, and the conical surface of this cone (6: 100) is at its outer surface, and at small-sized medical latex cover of conical surface suit, and the head of rubber finger sleeve is inhaled into the inner chamber of cone in advance when assembling.The head that needs only during use overcoat inserts cone, the cone that have syringe needle and rubber finger sleeve this moment just becomes one with overcoat, during use, along with pulling out gradually of core bar, the head of rubber finger sleeve can plough under the inner chamber of overcoat automatically from the inner chamber of cone under the effect of pull of vacuum, liquid medicine enters rubber finger sleeve simultaneously, along with pulling out of core bar, liquid medicine can constantly be followed constantly dilating of rubber finger sleeve and constantly enter, and is sucked end up to liquid medicine.Just can inject this moment.After injection finished, the head of rubber finger sleeve can enter the inner chamber of cone again automatically under the effect of core bar pressure.Take off and throw into special garbage can as long as will justify the diet body with tweezers from the overcoat head this moment.This shows, liquid medicine also can take place directly to contact in the overall process that is sucked and injects with overcoat and core bar, therefore, the injection tool that overcoat and core bar can life-time service with regard to can be used as a kind of need not disinfecting, depleted only is this very little part of cone.
In addition, an envelope seat of being made up of silica gel sheet and spring is housed at the top of core bar, and it has acted on sealing and buffering effect, also more can see clearly simultaneously on the outer reticule that puts.
Before the use, cone during use, as long as open box, inserts overcoat on the cone conical surface, just can equally with traditional injection use with in 50 the one group box that is sealed in a particular design.
This utility model utilizes rubber finger sleeve to dilate coefficient to reach 7-8 characteristics doubly; carry out ingenious design; set up an envelope seat simultaneously; it is strong to make the environment-friendly type syringe have waste discharge gas ability; energy resource consumption is low, and is easy to operate, good hand touch; the characteristics very favourable to environmental conservation are the medical apparatus and instruments of a new generation's injection both at home and abroad.
