Abstract
The utility model discloses an injection syringe with a lateral joint. The injection syringe comprises a body with the joint, the side wall of the body is provided with an opening, an inner barrel body is arranged in the body, a hole in butt joint with the joint is formed in the side wall of the inner barrel body, and a plunger and a push piece are arranged in the inner barrel body. The joint of the injection syringe can be connected with the injection syringe, a medical hose and other joints, an ampoule bottled container is not needed, and injections are directly drawn through the cooperation of the joint and a large-capacity container. The injection syringe is convenient to use and prevents seepage.
Description
Technical field
This utility model relates to field of medical appliances, relates in particular to a kind of side joint syringe.
Background technology
Many injection all adopt ampoule bottle packing clinically, during use, must break ampoule bottle into two with one's hands, easily cause accidental puncture, the ropy words of ampoule bottle also can make glass fragment be spilled in bottle, while needing under special circumstances to use in a large number the bottled injection of ampoule, to break a large amount of ampoule bottles into two with one's hands, increase medical personnel's workload, in extraction process repeatedly, also easily caused pollution.Also have some to adopt other modes, but because injection characteristic can not adopt rubber capping packing, therefore can not utilize syringe to extract.
Utility model content
Goal of the invention: the purpose of this utility model be to provide a kind of with side joint for coordinating injection container or puncture needle
Technical scheme: for achieving the above object, a kind of side of the present utility model joint syringe, comprising that sidewall opening is provided with in the body of joint, described body is provided with inner barrel, and described inner barrel sidewall is provided with the hole of docking with described joint, is provided with plunger and impeller in inner barrel.
This utility model, by body and the inner barrel of combination mutually, is realized the closure of joint perforate by rotation inner barrel.Because inner barrel and body sidewall have corresponding ，Dang hole, hole when the overlap condition, passage is circulation status, can extract injection by joint; Extract after injection, rotate inner barrel, hole is blocked, press impeller and the injection of plunger front end can be injected away from front end pin hole.In order to guarantee that the injection of extraction is drawn onto to plunger front end, need first plunger to be moved to joint and described hole tail end, the passage that injection is entered is exposed in plunger front end cavity, then pulls back impeller extraction injection.
In order to realize the rotation of inner barrel, described inner barrel tail end is provided with the ring rotation handle vertical with body axis.In order to prevent that rotating inner barrel occurs skidding, described rotating handle is provided with anti-skidding teeth groove.
As further optimization of the present utility model, between described inner barrel and body, be provided with at least two group sealing rings and at inner barrel and body sidewall for limiting the groove of sealing ring, thereby guarantee that sealing ring can migration.More particularly, between described inner barrel and body, the both sides near joint are respectively equipped with a sealing ring.Whether the injection that the sealing property of sealing ring directly has influence on syringe absorption there is seepage, as further optimization, described inner barrel outer surface is also provided with the annular sealing member corresponding with described hole size, when rotating inner barrel to assigned address, this annular sealing member is just in time realized the sealing to hole, prevent that the injection of intracavity can outwards overflow through hole from the gap between inner barrel and body when pushing impeller.
Beneficial effect: the joint of a kind of side of the present utility model joint syringe can be connected with syringe, flexible pipe for medical purpose and other joints, does not need to utilize ampoule bottle packaging container, directly coordinates large-rolume container to extract injection by joint.This utility model is economical and practical, easy to use, prevents seepage, has good prospect of the application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that this utility model extracts the operation instruction figure of injection from joint.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is further described.
Shown in Fig. 1, Fig. 2, a kind of side of the present utility model joint syringe, comprises the inner barrel 3 being closely abutted against in the shape body similar to conventional syringe 2, body, and inner barrel is provided with plunger 5 and the impeller 6 being connected.The sidewall opening of body 2 is provided with joint 1, and inner barrel 3 sidewalls are provided with the hole 4 of docking with joint 1.Inner barrel 3 tail ends are provided with the ring rotation handle 7 vertical with body 2 axis, and rotating handle 7 is provided with anti-skidding teeth groove 8.Between inner barrel 3 and body 2, be provided with at least two group sealing rings 9 and at inner barrel 3 and body 2 sidewalls for limiting the groove of sealing ring.Both sides near joint 1 place between inner barrel 3 and body 2 are respectively equipped with a sealing ring 9.
When the opening of hole 4 and joint 1 is during in overlap condition, passage is circulation status, can extract injection by joint 1; Extract after injection, rotate inner barrel 3, hole 4 is blocked, press impeller 6 and the injection of plunger 5 front ends can be injected away from front end pin hole.In order to guarantee that the injection of extraction is drawn onto to plunger front end, need first plunger to be moved to joint 1 and described hole tail end, the passage that injection is entered is exposed in plunger 5 front end cavitys, then pulls back impeller 6 extraction injection.
It should be noted that; joint described in the utility model can be realized by the change of type, shape and structure various ways and extract injection; joint of the present utility model can be used as the special joint with other container collocation; also can be the ordinary couplings for connecting hose; also can be the screwed union that puncture needle is installed; therefore; joint geometry of the present utility model and structure are not limited to subsequent embodiment scope of disclosure, and the joint categories that belongs to the present utility model design all should be in protection domain of the present utility model.
