Abstract
The utility model relates to a medicine injecting device without a needle, which comprises a T-shaped pipe, wherein an elastic pad is arranged in a medicine adding hole of a three-way interface of the T-shaped pipe, and the middle part of the elastic pad is provided with a cut. A clamping hoop is fixed on the medicine adding hole of the three-way interface of the T-shaped pipe. A protective cover is buckled on the clamping hoop so as to have a protective function, and the clamping hoop is connected with the protective cover. In common conditions, the straight cut of the elastic pad is in a closed state. Under the action of outer force, the straight cut of the elastic pad is opened and the front end of a syringe is convenient to pass. Because the T-shaped pipe 1 is connected to a medical pipeline, a pushing handle of the syringe is pushed by operators and liquid medicine is injected in the medical transfusion pipeline through the straight cut 5 which is opened. When used, the utility model has the advantages of safety, environmental protection, convenient operation, etc.
Description
Affiliated technical field
This utility model belongs to medical instruments field, relates to infused drug device in medical tubing.
Background technology
Traditional mode of adding medicine in medical tubing, the general syringe of band syringe needle that adopts is injected into medicine in the T shape pipe that has the rubber interface, then by medical tubing input human body.Its shortcoming: one, T shape interface tube rubber repeatedly punctures through syringe needle, very easily falls foam, and causes blood (medicine) liquid seepage and pollution thus; Its two, adopt the syringe needle puncture, easily medical personnel are damaged; Its three, with after discarded syringe needle be not easy to destroy, cause environmental pollution.
Summary of the invention
The purpose of this utility model provides a kind of needleless medicine-filling device that does not need with the syringe needle puncture.
The purpose of this utility model is achieved in that a kind of needleless medicine-filling device, comprises T shape pipe, and a word otch is arranged in the middle of the flexible pad in the three-way interface dosing hole of T shape pipe, cushion; Clip is fixed on the three-way interface dosing hole of T shape pipe.Over cap is buckled on the clip, plays a protective role, and clip can be connected with over cap.Under normal conditions, cushion one word otch is in closure state; Under external force, cushion one word otch is opened, and the front end of being convenient to syringe passes through.
Adopt this utility model, have safety, environmental protection, advantage such as easy to operate.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Figure 1A is a front view of the present utility model, and Figure 1B is a vertical view of the present utility model;
Fig. 2 is a T shape tubular construction sketch map;
Fig. 3 is the cushion structural representation;
Fig. 4 is clip and over cap structural representation.
Wherein: 1-T shape pipe, 2-cushion, 3-clip, 4-over cap, 5-one word otch
Specific embodiments
1 one kinds of needleless medicine-filling devices of embodiment (seeing Figure 1A, Figure 1B) are provided with cushion 2 (seeing Fig. 2, Fig. 3) in the dosing hole of T shape pipe 1, a word otch 5 is arranged in the middle of the cushion 2; Cushion 2 can adopt macromolecule medical silica-gel or elastomeric material to make.Clip 3 is fixed on the top, three-way interface dosing hole of T shape pipe 1.Over cap 4 is buckled on the clip 3, plays anti-pollution and guard block effect, clip 3 can with over cap 4 (see figure 4) that is flexible coupling.During use, the operator opens over cap 4, and the syringe of hand-held needleless with syringe front end puncture cushion 2, opens a word otch 5 of cushion 2; One word otch 5 tightly blocks the syringe front end based on elasticity.Because T shape pipe 1 is connected in the medical tubing, operator's push injection device pushes away handle, just medicinal liquid can be injected the medical infusion pipeline by a word otch 5 of opening.After adding medicine and finishing to extract syringe, a word otch 5 of cushion 2 recovers closure states, covers over cap 4 at last again.
Claims (2)
1, a kind of needleless medicine-filling device comprises T shape pipe, it is characterized in that flexible pad in the three-way interface dosing hole of T shape pipe, and a word otch is arranged in the middle of the cushion; Clip is fixed on the three-way interface dosing hole of T shape pipe.
2, a kind of needleless medicine-filling device according to claim 1 is characterized in that over cap is buckled on the clip, and clip can be connected with over cap.
