Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 5, an intravenous infusion apparatus convenient for safe injection comprises a tube body 1, a bottle stopper puncture outfit 2 and a needle 7, wherein a drip cup 3, a speed-regulating switch 4 and a medicine feeding port 6 are sequentially arranged on the tube body 1 between the bottle stopper puncture outfit 2 and the needle 7, the needle 7 is detachably connected with the medicine feeding port 6, and a flow stopping clip 5 is clamped between the needle 7 and the medicine feeding port 6 and used for blocking the circulation of liquid medicine in the tube body 1; one end of the flow stopping clamp 5 is provided with a clamp handle 10, the middle part of the flow stopping clamp 5 is provided with an oval clamp opening 9, and the inner wall of the oval clamp opening 9 is provided with clamp teeth 901 which are arranged in an interrupted spiral manner and are used for clamping and blocking the liquid medicine in the pipe body 1, the flow stopping effect is better through spiral arrangement, and the damage to the pipe body 1 is reduced; a shaping opening 8 is formed in the flow stopping clamp 5 on one side of the oval clamping opening 9, so that the clamped pipe body 1 with clamping marks can be quickly and basically restored to the original state, a torsion spring supporting rod 11 is arranged between the clamping handles 10, a torsion spring 12 is arranged on the torsion spring supporting rod 11, and flat clamping teeth 501 are arranged between the oval clamping opening 9 and the shaping opening 8 and can be conveniently used as a conventional clamp; the flow stopping clamp 5 is clamped on the pipe body 1 through the shaping opening 8.

Wherein, the maximum diameter of oval clamp mouth 9 is greater than the external diameter of body 1, is convenient for realize that oval clamp mouth 9 presss from both sides the clamp of body 1.

Wherein, moulding mouth 8 is whole circularly, and the internal diameter of moulding mouth 8 equals the external diameter of body 1, realizes resumeing by the 1 form of body of pressing from both sides flat, and the port department of moulding mouth 8 is the smooth cambered surface through polishing treatment, and increase port area is convenient for slip extrusion body 1 and resumeing tubular.

Wherein, the bottom side of the flow stopping clamp 5 is provided with a holding groove, which is convenient for hand holding operation.

The longitudinal distance between the clamping teeth 901 in the original state is smaller than the inner diameter of the pipe body 1, and the distance ensures that the clamping teeth 901 can clamp the pipe body 1 flat to achieve the effect of stopping flow.

It should be noted that, the utility model relates to a venous transfusion system convenient to inject safely, when specifically working, at first in the infusion process, if need inject the medicine through the vein, can press from both sides the mode that the flow stopping presss from both sides 5 on the body 1 through moulding mouth 8, change into and press from both sides on the body 1 through oval clamp mouth 9, the interrupted spiral heliciform that is arranged on the inner wall of oval clamp mouth 9 presss from both sides tooth 901 around the body 1 and presss from both sides it tightly at this moment, realize the flow stopping of liquid medicine, open the medicine feeding mouth 6 at this moment and inject the liquid medicine into the pipe through the syringe, then put into medicine feeding mouth 6, again clamp moulding mouth 8 of flow stopping clamp 5 on one side that the body 1 has the clamp mark, then hand grip the flow stopping clamp 5 and slide on the body 1, because the internal diameter of moulding mouth 8 equals the external diameter of body 1, and the body is pressed from both sides the back diameter and is the platykurtic, therefore when moulding mouth 8 slides, the pipe body 1 with the clamping mark can be extruded to the original shape gradually and quickly.
