Abstract
The utility model relates to a disposable needleless drug-adding three-way tube which comprises a three-way seat, and a transverse channel penetrates the inside of the three-way seat; and a drug-adding connector, a sealing rubber plug and a spring are also included. A hollow ladder-shaped hole is arranged in the drug-adding connector, and the drug-adding connector is in threaded conection with a connector with external taper; and the sealing rubber plug and the spring are installed in the ladder-shaped hole of the drug-adding connector, one end of the spring is propped against the three-way seat, while the other end of the spring is propped against the sealing rubber plug so as to seal one end of the ladder-shaped hole. The drug-adding three-way tube is changed into the needleless drug-adding three-way tube, and the structure is improved, so that the risk of puncture wound from the needle is avoided, and the pollution of the needle tube to the liquid medicine is reduced.
Description
Technical field
This utility model relates to the transfusion device accessory that uses in a kind of medical treatment, the threeway of particularly a kind of disposable use Needleless dosing.
Background technology
In the medical procedure of each medical institutions, transfusion is one of therapeutic modality of using always.And along with the variation of conditions of patients, often need be in normal infusion process the different medicinal liquid of filling.Common dosing mouth generally all needs to be with the pin apparatus to puncture, and in use, medical personnel's plug that pin need be punctured may cause pricking wound, moreover the use of needle tubing, has introduced the risk of needle tubing to liquid medicine contamination again.So it is very important designing a kind of chemicals dosing plant that need not the participation of needle tubing.
The utility model content
Technical problem to be solved in the utility model provides the threeway of a kind of disposable use Needleless dosing, this disposable use Needleless dosing threeway can insert transfusion device and use for clinical dosing, and is simple in structure, easy to use, and need not the participation of needle tubing, rationally safety.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
The threeway of disposable use Needleless dosing comprises the threeway seat, and an interconnection that runs through is arranged in this threeway seat; It is characterized in that, also comprise
Dosing connector has the stepped hole of a hollow in the described dosing connector, described dosing connector with have the external taper joint screw thread and be connected;
An one sealing plug and a spring, sealing plug and spring are installed in the stepped hole of described dosing connector, and an end of described spring props up described threeway seat, and the other end withstands the sealing plug, to seal up an end of described stepped hole.
Spring of the present utility model adopts taper spring, and a wherein large diameter end props up described threeway seat body, and an end of minor diameter withstands described sealing plug.Adopt taper spring, can apply a higher power, thereby guarantee that the sealing plug can seal up dosing connector well to the sealing plug.
This utility model dosing connector is provided with the locked groove that is connected with the infusion apparatus that has the external taper joint, and infusion apparatus can be connected with dosing connector stabilized seal ground.
The infusion apparatus that this utility model and syringe or other have the external taper joint use that matches so that the medicine in the infusion apparatus is introduced the threeway seat, makes things convenient for dosing; Concrete grammar is: described Needleless dosing threeway allows directly to adopt syringe or other to have the infusion apparatus of external taper joint, inserts or screw-in locking-type nipple, and spring is pushed away downwards, and the cork position descends, and heparin or other liquid can normally be imported; After liquid was totally lost, after pulling out infusion apparatus and leaving the locking-type nipple, spring was upspring automatically, rise on the cork position and restore, and with Needleless dosing threeway sealing, no liquid is leaked.
The beneficial effects of the utility model are, the dosing threeway becomes the Needleless dosing threeway, and structure improves, and have so just avoided the pricking wound risk and have reduced the pollution of needle tubing to medicinal liquid.

Fig. 2 is the cutaway view of the disposable use Needleless dosing of this utility model threeway.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth this utility model.
Referring to Fig. 1, Fig. 2, the threeway of disposable use Needleless dosing, it comprises threeway seat 1, dosing connector 2, sealing plug 3, spring 4.Have in the threeway seat 1 interconnection that runs through is arranged in the threeway seat.Dosing connector 2 with have external taper joint infusion apparatus and be threaded.
The stepped hole that has a hollow in the dosing connector 2, this stepped hole comprise first hole 21 and second a slightly little hole 22 of diameter that diameter is big slightly, and the free end in first hole 21 is provided with female thread so that with have external taper joint infusion device and be threaded.Dosing connector 2 is provided with the locked groove 23 that is connected with the infusion apparatus that has the external taper joint, and infusion apparatus can be connected with dosing connector 2 stabilized seal ground.This locked groove 23 can be slot or spin slot.Sealing plug 3 is inserted into second hole 22 from first hole, 21 sides, forms the sealing to dosing connector 2; Spring 4 is installed in first hole 21, and an end of spring 4 props up threeway seat 1, and the other end withstands sealing plug 3, to seal up dosing connector 2.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in the foregoing description and the description just illustrates principle of the present utility model; this utility model also has various changes and modifications under the prerequisite that does not break away from this utility model spirit and scope, and these changes and improvements all fall in claimed this utility model scope.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
