Abstract

The utility model provides a transfusion device easy to see blood return, comprising a transfusion needle 1, a drip pipe 2, a transfusion pipe 3, a regulating switch 4, a joint 5 for an injection needle head and the injection needle head 6. The utility model is characterized in that at least one compressor 7 out of a pipe is additionally arranged below the drip pipe 2 to the injection needle head 6. When the utility model is used, transfusion liquid is filled into a transfusion pipeline below the liquid level of the drip pipe, the regulating switch is closed to block liquid flow, the compressor below the regulating switch is fastened, and injection is processed after a plurality of liquids are dripped from the injection needle head. The injection course is completed, and the effects that the phenomenon of the blood return is easy to see and the transfusion liquid is prevented from existing in tissues are obtained.

Description

A kind of easy viewing blood return transfusion device
This utility model belongs to the medical Transfusion device technical field.
The disposable medical transfusion device is one of medical apparatus commonly used at present, its basic structure is by transfusion needle, dropper, tube for transfusion, by-pass cock and injection needle are formed, before intravenous operation, must make from dropper liquid is flat and inject again in the pipeline of injection needle, to be full of input liquid, and full of liquid in the tube for transfusion, injection needle enters behind the vein difficulty and sees the blood backflow phenomenon, the operator is difficult to then determine whether syringe needle enters vein, treating method commonly used is the extruding tube for transfusion, discharge section liquid, cause negative pressure to be beneficial to observe blood back, if but injection needle does not enter vein, the liquid intravasation surrounding tissue of discharging makes angiectopia, sink etc., increase the further difficulty of puncture; Or cause the part to be swollen with, and must change injection position again, increase patient's the misery and the trouble of operation, so this is a technical problem that urgency is to be solved.
This utility model is intended to propose a kind of easy viewing blood return transfusion device, reaches both easy for looking back flow of blood phenomenons, can avoid importing liquid again and be present in effect between tissue.
A kind of easy viewing blood return transfusion device that the utility model proposes comprises transfusion needle, dropper, tube for transfusion, by-pass cock, injection needle joint and injection needle, it is characterized in that at dropper to increase compressor outside at least one pipe between injection needle.
The form of compressor is varied, and can increase clamp or cap bag or cingulum or increase another by-pass cock, or by at least simultaneously having the pipeline in an above duct to add stopper or clasp; Also can merge compressor and by-pass cock, promptly install one again and regulate spiral shell or cingulum or cap bag or clamp or have at least a segment length to go out the base plate, side plate etc. of former switch, also can the same manner merge with compressor and entry needle joint or with dropper in same switch baseplate bottom.
Because a kind of easy viewing blood return transfusion device that the utility model proposes, comprise transfusion needle, dropper, tube for transfusion, by-pass cock, injection needle joint and injection needle, it is characterized in that at dropper between injection needle, to increase compressor outside at least one pipeline, the form of compressor is varied, can increase by-pass cock in addition, or clamp, or cap bag etc., also can be compressor and by-pass cock, or merge with dropper, be full of input liquid with pipeline with dropper liquid is flat during use down to injection needle, close by-pass cock blocking-up liquid stream, the compressor of fastening by-pass cock below, after oozing several drop of liquid from injection needle, inject again, unclamp compressor then, make and form a vacuum zone in the tube for transfusion, if injection needle has entered vein, then see obvious blood back phenomenon easily, if injection needle does not enter vein, then can continue puncture to syringe needle along the vein direction, until blood back occurring, finish injection process, can improve intravenous operating technology, reach both easy for looking back flow of blood phenomenons, can avoid importing liquid again and be present in effect between tissue.
Below in conjunction with embodiment and accompanying drawing this utility model is further described.
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the structural representation of another embodiment of this utility model;
Fig. 3 is the structural representation of the another embodiment of this utility model.
With reference to Fig. 1, a kind of easy viewing blood return transfusion device that the utility model proposes, comprise transfusion needle 1, dropper 2, tube for transfusion 3, by-pass cock 4, injection needle joint 5 and injection needle 6, it is characterized in that at dropper between injection needle, to increase compressor 7 outside at least one pipe, compressor 7 is to increase another by-pass cock below the by-pass cock 4 of transfusion device, sterilization routinely before the use, transfusion needle is inserted in the infusion bottle, open by-pass cock 4, discharge dropper air until syringe needle 5 below 2, make and be full of input liquid in the tube for transfusion, close by-pass cock 4 blocking-up liquid stream, the compressor 7 of fastening by-pass cock 4 belows, after oozing several drop of liquid from injection needle 6, unclamp compressor 7 after syringe needle thrust body tissue, make and form a vacuum zone in the tube for transfusion 3, if injection needle 6 has entered vein, then see obvious blood back phenomenon easily, if injection needle 6 does not enter vein, then can continue puncture to syringe needle along the vein direction, until blood back occurring, finish injection process, so can improve intravenous operating technology, reach both easy for looking back flow of blood phenomenons, can avoid importing liquid again and be present in effect between tissue.
