Abstract
The utility model belongs to medical apparatus, particularly relates to a syringe needle for dissolving powder medicine for injection. A side tube is added to the original syringe so as to enable the syringe tube to have a one-body-double-tube structure, wherein the two ends of the side tube are respectively opened at one side of the syringe near the needle seat and needle point, the opening of the syringe tube is opened at the other side thereof near the needle point, and the syringe tube is not communicated with the side tube. The needle point adopts a round and smooth solid needle point without opening. When the water for injection is injected into the powder for injection bottle through the syringe needle, the pressure in the bottle increases, and the gas flows out through the side tube. After the medicine is completely dissolved, as the powder liquid for injection is being drawn out, the pressure in the bottle decreases, and the external gas goes into the powder for injection bottle through the side tube. The pressures in and out of the bottle are balanced under the action of the side tube, so that injecting the water for injection and drawing the dissolved medicine liquid become very easy. Therefore, by the adoption of the syringe needle, the medicine dissolving time is saved, the labor intensity of nursing staff is relieved, and the number of the particles falling into the bottle is decreased so as to prevent the contamination.
Description
Technical field:
This utility model belongs to a kind of medical apparatus and instruments, especially relates to the employed syringe needle of a kind of dissolving injectable powder medicine.
Background technology:
According to the difference of medicine stability, many medicines need be made into injectable powder, need during clinical use earlier medicine is dissolved, then intramuscular injection or add the injection of diluent medium-sized vein.Traditional method is to connect the normal injection syringe needle with the 20-30ml syringe to extract water for injection injection powder pin apothecary jar, after treating that medicine fully dissolves, the medicine after the former syringe of reuse will dissolve is extracted out, carries out intramuscular injection or adds the injection of diluent medium-sized vein, operating process is simple, is easy to grasp.But because the influence of positive/negative pressure, often require great effort very much when in the powder syringe and medicine bottle, injecting the medicine after water for injection and extraction are dissolved, generally need to extract out in advance or inject air and finished afterwards, waste time and energy, nurse's palm of being engaged in this work for a long time often all grinds hard cocoon.Because normal injection needle tip inclined-plane repeated localised puncture powder medicine administered by injection thing rubber bottle cap is brought rubber particle in the infusion bottle into easily, pollutes and infusion reaction.
Summary of the invention:
The disclosed purpose of this utility model be exactly the deficiency when being used to dissolve the injectable powder medicine at above-mentioned normal injection syringe needle and provide pass through to change needle point structure and increase by a side pipe make dissolving powder medicine administered by injection thing become easier, more laborsaving, avoided particle contamination simultaneously.
Description of drawings:
Accompanying drawing is a kind of molten medicine syringe needle, is made up of needle stand 1, needle tubing 2, side pipe 3 and needle point 4.It is characterized in that the two ends of side pipe 3 are opened on the close needle stand 1 of a side and needle point 4 places of needle tubing 2 respectively, needle tubing 2 is opened on the opposite side near needle point 4 places, and needle tubing 2 and side pipe 3 are not connected.Needle point 4 is slick and sly shape, and real core does not have opening.
Fig. 1 is the overall structure sketch map of a kind of molten medicine syringe needle of this utility model, wherein: 1-needle stand, 2-needle tubing, 3-side pipe, 4-needle point.
The specific embodiment:
Narrate the implementation procedure of a kind of molten medicine syringe needle of this utility model in conjunction with the accompanying drawings:
A kind of molten medicine syringe needle of this utility model, structure is very simple, only need on the basis of normal injection syringe needle, to improve a little and just can realize, specific practice is: needle tubing 2 is made one two pipes, side pipe 3 diameter 0.2-0.3mm, 3 liang of holes of side pipe are opened on needle tubing 2 one sides respectively near needle stand 1 and needle point 4 places, and needle tubing 2 is opened on the opposite side near needle point 4 places, and needle tubing 2 and side pipe 3 are not connected.Needle point 4 is slick and sly shape, and real core does not have opening.
Use: pricker breaks the injectable powder bottle cap, sterilization, connect after molten medicine syringe needle extracts water for injection with syringe, in the perpendicular insertion people powder injection bottle, it is too dark not sting the people, and opening that should side pipe 3 nearly needle points 4 places enters that 0.5-1.0cm is good in the powder injection bottle, and water for injection is injected in the powder injection bottle, at this moment pressure of the inside of a bottle increases, and gas flows out along side pipe 3 in the powder syringe and medicine bottle.After treating that medicine dissolves fully, begin suction, powder syringe and medicine bottle internal pressure descends, and under suction function, ambient atmos enters in the powder injection bottle along side pipe 3.Whole process makes injectable powder medicine bottle external and internal pressure keep balance by side pipe 3, makes to inject and aspirate to be very easy to.Because needle tubing 2 is opened on a side, needle point 4 is slick and sly shape, has avoided the puncture of common needle tip inclined-plane easily with the shortcoming in the medicine rubber particle band people infusion bottle.
A kind of molten medicine syringe needle of this utility model, reasonable in design, simple to operate, because the needle point slyness does not have opening, avoided microgranule to come off.Make injectable powder medicine bottle external and internal pressure keep balance by side pipe during dissolved substance, injection and suction become and are very easy to laborsaving.Promptly save the molten medicine time, alleviated nursing staff's labor intensity again, and reduced microgranule formation, avoided pollution.
