Abstract
The utility model provides a syringe adapter, which belongs to the technical field of a medical appliance. The syringe adapter adopts a three way tube structure, wherein, a straight tube tapered plug sleeve and a straight tube stopper are arranged on the inner wall of one straight tube in sequence from the crossing point of the three way tube to the far tube end of the straight tube; a straight tube tapered plug is arranged between the straight tube tapered plug sleeve and the straight tube stopper, and diameter of the straight tube tapered plug is smaller than the inner diameter of the straight tube; a branch tube stopper and a branch tube tapered plug sleeve are arranged on the inner wall of the branch tube of the three way tube in sequence from the crossing point of the three way tube to the far tube end of the branch tube, wherein, a branch tube tapered plug is arranged between the branch tube stopper and the branch tube tapered plug sleeve, and the diameter of the branch tube tapered plug is smaller than the inner diameter of the branch tube. The other straight tube of the three way tube is the connecting tube of the syringe. The syringe adapter has the advantages that the design is reasonable, the structure is simple, the operation is convenient, and the functions of once puncture and intermittent injection can be realized, and the syringe adapter can be widely applied to various intravenous injections, even to arterial injections.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of syringe adapter.
Background technology
General, when patient need inject more than one injections and this multiple injection because chemical effect and can not mixed once during injection, usually need do the injection of twice above puncture, highly difficult injection operation demand has not been satisfied in the use of the syringe that generally uses at this moment.Even in operation process, also need to develop the requirement that simple and convenient injection device efficiently satisfies current medical development.On the basis of the simple apparatus of unification at present, how designing and developing new equipment or auxiliary device and all the time has been that an important topic to be solved is arranged in the present stage technical field of medical instruments.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of syringe adapter that can realize multiple function of injection is provided.
The technical solution of the utility model realizes in the following manner, this syringe adapter, its structure is that this syringe adapter is a three-way pipe structure, be disposed with straight tube tapered plug holder cover and straight tube block from the tee T intersection point to the direction of the pipe end far away of this straight tube on one of them straight tube inwall of tee T, be provided with the straight tube conical plug between straight tube tapered plug holder cover and the straight tube block, the diameter of straight tube conical plug is less than the internal diameter of straight tube; Be disposed with between arm block and arm tapered plug holder cover, arm block and the arm tapered plug holder cover to the direction of the pipe end far away of arm from the tee T intersection point on the branch pipe wall of tee T and be provided with the arm conical plug, the diameter of arm conical plug is less than the internal diameter of arm.
Another straight tube of tee T is a syringe connection tube.
Straight tube tapered plug holder cover, straight tube block and straight tube are the unitary whole structures, and arm block, arm conical plug and arm are the unitary whole structures.
This syringe adapter integral body is transparent or semitransparent.
The beneficial effect that this utility model is compared with prior art produced is:
This syringe adapter is reasonable in design, simple in structure, easy to use, on the structure of tee T, add the inner block of pipe, stopper and Sai Tuo cover are set, the material that makes in the tee T injected or aspirate by syringe can directed flow, can realize the function of one-time puncture intermittent infusion, be widely used in multiple intravenous injection, even on the intra-arterial injection.

The specific embodiment
Below in conjunction with accompanying drawing syringe adapter of the present utility model is done following detailed description the in detail.
Shown in accompanying drawing 1,2,3, syringe adapter 1 integral body of the present utility model is transparent three-way pipe structure, be disposed with straight tube tapered plug holder cover 4 and straight tube block 6 from the tee T intersection point to the direction of the pipe end far away of this straight tube on one of them straight tube 3 inwall of tee T, be provided with straight tube conical plug 5 between straight tube tapered plug holder cover 4 and the straight tube block 6, the diameter of straight tube conical plug 5 is less than the internal diameter of straight tube 3; Straight tube tapered plug holder cover 4, straight tube block 6 and straight tube 3 are unitary whole structures.Another straight tube of tee T is a syringe connection tube 2.Be disposed with between arm block 8 and arm tapered plug holder cover 10, arm block 8 and the arm tapered plug holder cover 10 to the direction of the pipe end far away of arm from the tee T intersection point on arm 7 inwalls of tee T and be provided with arm conical plug 9, the diameter of arm conical plug 9 is less than the internal diameter of arm 7.Arm block 8, arm conical plug 10 and arm 7 are unitary whole structures.
This syringe adapter is applied in above the syringe, adopt the choked flow of conical plug, make liquid between straight tube and arm, form the state of two kinds of directed flow: the one, when syringe is injected, the arm conical plug upwards withstands arm tapered plug holder cover applying sealing, makes the directed straight tube (as shown in Figure 1) that advances of liquid in the syringe; The 2nd, when syringe pump, straight tube conical plug and straight tube tapered plug holder cover are fitted and are sealed, the liquid (as shown in Figure 4) of the directly directed suction arm of syringe.
Claims (4)
