The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

By Fig. 1, Fig. 2 as can be seen, the infusion set of present embodiment comprises puncture needle 1, Paracentesis needle holder 4, keeps somewhere flexible pipe 2, keeps somewhere needle stand 3, chemical feed pipe 5, infusion tube 7, medicinal liquid input pipe 8 and calparine cap 9.Puncture needle 1 is fixed on the Paracentesis needle holder 4, forms integrative-structure.Keeping somewhere needle stand 3 is the inner hollow structure, forms a cavity, keeps somewhere flexible pipe 2 and is installed on the indwelling needle stand 3, and the pipe internal cavity of keeping somewhere flexible pipe 2 communicates with the internal cavities of keeping somewhere needle stand 3.The puncture needle 1 that is fixed on the Paracentesis needle holder 4 can enter from the internal cavities of keeping somewhere needle stand 3, penetrate the pipe internal cavity of keeping somewhere flexible pipe 2, the length of puncture needle 1 is for exposing slightly after inserting fully a bit outside keeping somewhere flexible pipe 2, just exposes with the pin hole of puncture needle 1 and is advisable.Chemical feed pipe 5 is arranged on to be kept somewhere on the needle stand 3, chemical feed pipe 5 is provided with check valve 15 with the bottom that indwelling needle stand 3 is communicated with, do not add at chemical feed pipe 5 and to close when being used as medicine, the pipe internal cavity of chemical feed pipe 5 does not communicate with the internal cavities of keeping somewhere needle stand 3, only when dosing, when externally medicinal liquid was exerted pressure by syringe or other medical apparatus and instruments, the pipe internal cavity of chemical feed pipe 5 just communicated with the internal cavities of keeping somewhere needle stand 3, medicinal liquid is entered in the internal cavities of keeping somewhere needle stand 3, thereby be input among the patient body.The top of chemical feed pipe 5 is provided with dosing pipe cap 6, during not dosing, dosing pipe cap 6 is covered chemical feed pipe 5, can prevent that antibacterial, virus, dust etc. from polluting chemical feed pipe 5.Extension is provided with backplate 11 to one or both sides to keep somewhere needle stand 3 bottoms, and the shape of backplate 11 can be different shape, and is for example butterfly-like.Keep somewhere needle stand 3 and be provided with hose connection, keeping somewhere needle stand 3 is connected with infusion tube 7 by hose connection, the other end of infusion tube 7 is connected with medicinal liquid input pipe 8, medicinal liquid input pipe 8 can be common drug liquid input pipe (as shown in Figure 2), have a medicinal liquid inlet, the medicinal liquid inlet seals with calparine cap 9.Medicinal liquid input pipe 8 also can be Y-piece (as shown in Figure 3).Y-piece has two medicinal liquids inlet, and medicinal liquid inlet is with calparine cap 9 sealings, another one medicinal liquid inlet plastic cap sealed, and two medicinal liquids inlets can advance medicine simultaneously, also can be from a medicinal liquid into medicine that enters the mouth.Infusion tube 7 is provided with clamp 10, and clamp 10 is provided with the hole 13 of a diameter greater than infusion tube 7 diameters, and infusion tube 7 is through in the hole 13, and clamp 10 can move on infusion tube 7 flexibly.13 upper ends, hole have a draw-in groove 14, and the width of draw-in groove 14, can make infusion tube 7 distortion cut off the mobile of medicinal liquid and be advisable after infusion tube 7 is snapped in less than the internal diameter of infusion tube 7.In the time will closing transfusion, infusion tube 7 is snapped in draw-in groove 14 interior getting final product.In addition, draw-in groove 14 also can be designed as taper, and 13 marginal position diminishes along the center of circle direction width away from hole 13 draw-in groove gradually from the hole, controls thereby can utilize draw-in groove to block 7 pairs of medicinal liquid flows of infusion tube.When patient performs the operation, this device can be under the prerequisite of a venous transfusion, syringe needle is inserted in the calparine cap 9, and input anesthetis is imported medicine by puncture needle 1, when emergencies such as blood pressure reduction, bradycardia occurring as patient, can pass through the quick administration of chemical feed pipe, realize the purpose of transfusion, loading and quick administration simultaneously, both alleviate patient's wound and misery, reduced medical workers again, made things convenient for the rescue of clinical worker the patient that is critically ill.Also reduce the use of disposable medical article, thereby reduced patient's financial burden, reduced resource consumption, also reduced disposable medical rubbish and formed, reduced environmental pollution.

In addition, in order to solve remaining needle, on the basis of above-mentioned infusion set, be provided with rubber-like sealing stifled 12 at the end (end is meant away from an end of keeping somewhere flexible pipe 2) of the internal cavities of keeping somewhere needle stand 3 in the indwelling problem of vein long period.Referring to Fig. 4, sealing stifled 12 is made by no-toxicity medical elasticity flexible glue, is preferably made by rubber, has high resiliency.Puncture needle 1 can thrust sealing and block up 12, enters into the internal cavities of keeping somewhere needle stand 3, and then enters in the indwelling flexible pipe 2, and after puncture needle 1 was extracted, the high resiliency of sealing stifled 12 made it seal pin hole at once.Like this, when the transfusion loading finishes, transfusion device can be pulled out, by simply handling in 9 pairs of remaining needles of calparine cap, as inject a little normal saline or heparin water, and infusion tube 7 is snapped in the draw-in groove 14 of clamp 10 and make its obturation, blood can not reflux and solidify like this, also can not block and keep somewhere flexible pipe 2, when infusing next time, syringe needle is penetrated calparine cap 9 can be used.Generally speaking, remaining needle can keep about a week, the basic treatment cycle needs that satisfy a surgical patient or common patient, so just alleviated the misery of venous patient repeated localised puncture greatly, and reduce the financial burden, and reduced resource consumption, and also reduced disposable medical rubbish and formed, reduced environmental pollution.

As can be seen from the above embodiments, this utility model embodiment can give under the prerequisite of a venous transfusion of patient by medicinal liquid input pipe, puncture needle and chemical feed pipe, realize simultaneously to patient infuse, loading and the purpose of administration fast.This device had both alleviated patient's wound and misery, had reduced medical workers again, had made things convenient for the rescue of clinical worker to the patient that is critically ill.It is stifled by the end at the internal cavities of keeping somewhere needle stand sealing to be set, remaining needle is kept about a week at vein, the basic treatment cycle needs that satisfy a surgical patient or common patient, so just alleviated the misery of venous patient repeated localised puncture greatly, alleviated patient's financial burden, and reduced resource consumption, also reduced the formation of disposable medical rubbish, reduced environmental pollution.

The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from this utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
