Abstract
The utility model provides an internal pressure medicine storage type powder-injection combined feeding syringe characterized in that the syringe is provided with a solute bottle (14) and a solvent bottle (7) with internal pressure. A communicating tube (10) is arranged between the solvent bottle (7) and the solute bottle (14). The solvent bottle (7) and the solute bottle (14) are in sliding cooperation. The communicating tube (10) is a hollow body whose two ends are provided with pointed ends. The communicating tube (10) is provided with a limit plate (11). The structure design of the syringe is novel and unique with convenient and simple operation to reduce the nurse's operation procedure to avoid error. The entirety is in aseptic packaging with single use and low cost. The utility model is in particular suitable to be used for the hospital nurse to conduct intramuscular injection of powder-injection intramuscular injection and medicine feeding to the transfusion bottle and other daily uses.
Description
Technical field
This utility model relates to a kind of intrinsic pressure medicine storage type injectable powder combination medicine adding syringe.
Background technology
Injector for medical purpose in the past and medicine bottle and diluent all are relatively independent.When the nurse gives patient infusion powder (as penicillin etc.), penetrate medicine bottle again after will extracting diluent out with syringe earlier, releasing diluent dissolves powder, and then inhalation syringe could be implemented to inject.The whole operation process is more with thing, the program complexity, and syringe is polluted easily, also occurs adorning wrong medicine and the phenomenon that causes malpractice through regular meeting, nurse's operation is required extremely tight, and it is a bit careless to have, and nurse's mental pressure is too big.Domestic someone once applied for the patent of " injectable powder band pressing bottle formula syringe ", was that powder is loaded on an inner bag, relies on the Spina jujubae push away the handle front end to puncture inner bag medicated powder is mixed with diluent in the solute bottle under pressure, could implement behind the mixing to inject.Though this syringe is simple in structure, but still there is not satisfactory part.
The content of utility model
The technical problems to be solved in the utility model is for overcoming deficiency described in the prior art, and a kind of novel structure, intrinsic pressure medicine storage type injectable powder combination medicine adding syringe simple to operate are provided.
Technological improvement plan of the present utility model is: this syringe is provided with a solute bottle and has intrinsic pressure solvent bottle, is provided with a connecting pipe between solvent bottle and the solute bottle.
Further technological improvement of the present utility model is: described solvent bottle and solute bottle are for being slidingly matched.Communicating pipe is the ducted body of two ends band tip.On communicating pipe, be provided with banking stop.Outside the two prong heads that are connected with the solute bottle, be provided with the screw-like needle guard of making by flexiplast.In the said solvent bottle diluent is housed.
Because this syringe adopts by a communicating pipe two containers that solvent and solute are housed respectively being communicated with under external force, its structural design is unique novel, can make diluent under intrinsic pressure effect by injecting communicating pipe in the solute bottle, dissolve behind the mixing directly medicated powder to patient infusion or add in the infusion bottle, operate simple especially, for the nurse, can reduce operation link, the phenomenon of wrong medicine more can not occur adorning, alleviate nurse's psychological burden.Cause has added the screw-like needle guard of being made by flexiplast outside two prong heads, thus aseptic degree height, more can contaminated or cross-contamination.This syringe just according to dosage requires required medicated powder and corresponding diluent to pack into when producing, and whole syringe is aseptic packaging, and operation link does not contact outside air, and disposable use, does not have the probability of using repeatedly.This syringe is lower compared with the integrated cost of normally used medicated powder, ordinary syringe and diluent, main is simple to operation, reduce nurse's labor intensity, there is not the transfer of powder or diluent, be fit to large-scale production, and can be made into and be with intrinsic pressure or non-pressurized version, be specially adapted to hospital nurse carry out the injectable powder intramuscular injection, to infusion bottle dosing or the daily use by the dosing of infusion bottle conduit.

The specific embodiment
As shown in Figure 1, this utility model mainly is to be made of solvent bottle 7, solute bottle 14, two prong head 13, communicating pipe 10, piston 4.Wherein, piston 4 is loaded in the solute bottle 14, in the solvent bottle 7 that is filled with pressure and diluent 6 is housed be positioned at piston 4 tops, be equipped with the sealing plug of making by medical grade rubber or other nontoxic rubber 5,2 at the port of solvent bottle 7 and solute bottle 14.The two ends of communicating pipe 10 and two prong heads 13 are tip, and an end of two prong heads 13 inserts in the sealing plug 2; And the end of communicating pipe 10 inserts in the sealing plug 5, and its other end then stretches in the pit of piston 4.Protective sleeve 8 covers on outside solvent bottle 7 and the button 9, and cooperates with solute bottle 14 upper edges.On communicating pipe 10 and two prong head 13, all be fixed with banking stop 11,12.What solute bottle 14 terminations connection one was thin makes screw-shaped needle guard 1 by flexible non-toxic plastic.This embodiment is that solvent bottle 7 is inserted in a kind of structure in the solute bottle 14.
Fig. 2 shows another embodiment of the present utility model, is a kind of structure of solute bottle 14 being inserted in solvent bottle 7, and all the structure with Fig. 1 is identical for all the other.
Fig. 3 is another embodiment of the present utility model.Wherein solvent bottle 7 is identical with the external diameter of solute bottle 14, but on solvent bottle 7 and solute bottle 14 outer walls, be with a sleeve pipe 16, and be provided with a bulge loop 15 in the interior upper edge of solute bottle 14, increase and piston 4 is ejected in order to solute bottle 14 internal pressures after avoiding solvent bottle 7 and solute bottle 14 by communicating pipes 10 conducting, in fact piston 4 has been played position-limiting action.
The structure of communicating pipe 10 is not limited to the hollow structure of two ends tip, also can be horizontally installed with plunger valve with holes on communicating pipe 10, and the twisting valve handle can make solvent bottle and the conducting of solute bottle; Can also directly make solvent bottle and the conducting of solute bottle by the version that spurs or promote plunger valve with holes.
This syringe just according to dosage installs required medicated powder 3 during fabrication in the solute bottle, the diluent 6 of the corresponding dosage of in the solvent bottle, packing into, and give sufficient pressurising force in the solvent bottle.When maybe needing the infusion bottle dosing for patient infusion, remove protective sleeve and press button down, under external force, will make when the solvent bottle moves downward communicating pipe upwards to puncture sealing plug 5 and puncture piston downwards, thereby make solvent bottle and the conducting of solute bottle.Because the effect of solvent pressure of the inside of a bottle, diluent will be by being ejected in the solute bottle medicated powder dissolving and mixing communicating pipe.The interior pressure of this moment solvent bottle and solute bottle is in poised state.Again two prong heads and needle guard are aimed at the injection site or infusion bottle penetrates, its retroaction will make the upper end of two prong heads pierce through sealing plug 2.Simultaneously needle guard can be compressed into banking stop because of the skin of injection site or the stopping of plug of infusion bottle.Because of still there being rated pressure in the solute bottle, thus medicinal liquid will under the effect of pressure, inject in human body or the infusion bottle automatically, thereby finish once-through operation.
