Description

The automatic medicine-mixing drug feeding device

Technical field

This utility model relates to a kind of solvent bottle and solute bottle of making also can be to the automatic medicine-mixing drug feeding device of dosing in the infusion bottle by an inside and outside cover and the mutual conducting of conducting pin.

Background technology

When usually medical personnel implement dosing to infusion bottle, to extract according to quantity to inject behind the water for injection with ordinary syringe earlier and be equipped with in the cillin bottle that need add medicine, dissolve mixing after, all be drawn in the syringe again, and then in the injection infusion bottle.Owing to do not have more advanced device, so medical personnel can only be undertaken by the aforesaid operations program.And this program is too complicated, and operation link is too many, and work efficiency is lower, also occurs medicine or apparatus contamination easily, and then causes malpractice to take place.In order to solve the problem that exists in the reality, having Crinis Carbonisatus to understand pre-encapsulated injector, is in advance solvent and solute to be potted in two bottles, has plenty of the bottle of going up for being the cassette bottle for following bottle with intrinsic pressure cillin bottle, the upper and lower cassette bottle that is that has, connected mode are butt joint end to end.Though the syringe of this structure can reduce operation link, but it is comparatively complicated that topmost deficiency is a structure, can not with market on sold many decades the supporting use of powder ampoule agent for injection cillin bottle, if all use special cillin bottle then to need special making, cost can remain high.

Summary of the invention

The technical problems to be solved in the utility model is for overcoming the deficiencies in the prior art, provide a kind of and utilize commercially available powder ampoule agent for injection cillin bottle and realize being connected or conducting by a connecting device, and can give the automatic medicine-mixing drug feeding device of infusion bottle dosing with intrinsic pressure solvent bottle.

To achieve these goals, the utility model proposes practicable technical solution: the partition of conducting pin and interior cover is fixed, be equipped with elastomer between the dividing plate in partition and the overcoat, the bottleneck of solute bottle extend into the following space of overcoat dividing plate, and the bottleneck of solvent bottle be inserted in the upper end of cover, be respectively equipped with projection at the inwall of interior cover and overcoat.

Its further technical scheme is: the dividing plate center in overcoat is provided with the through hole that the conducting pin is passed.The card button of outer wall of inside race cooperates with chute and draw-in groove on the outer casing inner wall.The partition of cover in one end of conducting pin stretches out, and the other end is positioned at the through hole of overcoat.The bottleneck of the projection of overcoat and interior cover inwall and solute bottle and solvent bottle is an interference fit.

This device be with the powder ampoule agent for injection cillin bottles that use that sell for many years on the market and a large amount of as the solute bottle, need not manufacture special solute bottle, so both can make existing medicine bottle be able to good utilization, can reduce the production cost of this device again greatly.Since adopted inside and outside cover in conjunction with and conducting pin, elastomeric respective outer side edges, as long as one can make two bottles to realize the mixed medicines of conductings by solvent bottle or interior cover, then take out the solvent bottle and just can implement dosing infusion bottle.Operate very simple and conveniently, reduced all too many levels of original standard operation, reduced medical personnel's labor intensity, the more important thing is to have increased substantially work efficiency.

The specific embodiment

As shown in Figure 1, this utility model mainly is to be made of interior cover 8, overcoat 10, conducting pin 9, elastomer 11, solvent bottle 7, solute bottle 14.Wherein: laterally be provided with a partition 5 in the interior cover 8, be interval with arc convex 15 on interior cover 8 inwalls of partition more than 5, the lower edge external symmetry of interior cover 8 is provided with two card buttons 3.Overcoat 10 is one cylindric, also laterally is provided with a dividing plate 12 in it, also is interval with arc convex 13 on the outer casing inner wall of dividing plate below 12.Be arranged with the chute 4 with reverse draw-in groove 16 on overcoat 8 inwalls, two the card buttons 3 (referring to Fig. 5) outside interior cover 8 lower edges embed in chute 4 or the draw-in groove 16 (referring to Fig. 4).The conducting pin 9 of double headed roller point fixes with the partition 5 of interior cover 8.One end of conducting pin 9 stretches out partition 5, and the other end is positioned at the through hole 2 at overcoat 10 internal partitions 12 centers.Be enclosed within conducting pin 9 elastomer 11 outward between partition 5 and dividing plate 12.Have the cylindrical of intrinsic pressure solvent bottle 7 bottlenecks and projection 15 interference fit in the interior cover 8; And as the cylindrical of the common commercially available injectable powder medicine bottle bottleneck of solute bottle 14 usefulness and projection 13 interference fit in the overcoat 10.Fig. 1 has only shown solvent bottle and the solute bottle configuration state figure when conducting not.

When needs are realized solvent bottle and the mutual conducting of solute bottle to mix medicine, press solvent bottle 7 downwards with hands, simultaneously in cover 8 also move downward under external force, and compressing elastomer 11, card button 3 slides to draw-in groove 16 places for 4 times along chute, and in this process, the plug of solvent bottle 7 is pierced through in conducting pin 9 upper ends.When card button 3 is in draw-in groove 16 positions, the plug 1 of solute bottle 14 then can be pierced through in the lower end of conducting pin 9, make two bottles of conductings, the liquid vehicle in the solvent bottle 7 is pressed into solvent in the solute bottle 14 (referring to Fig. 2) by conducting pin 9 by the pressure of preliminary filling in the bottle, can realize mixing medicine.At this moment, be the medicinal liquid that has behind intrinsic pressure solvent and the solute mixing in the solute bottle 14.

After mixed medicine finishes, pull out solvent bottle 7, owing to removed external force, then will be under the effect of elastomer 11 with interior cover 8 tops to the extreme higher position (referring to Fig. 3), make the lower end of conducting pin 9 extract the plug 1 of solute bottle 14 simultaneously.Again conducting pin 9 upper ends are thrust the plug of infusion bottle this time, because the relation of counteracting force, interior cover 8 slides to draw-in groove 16 places for 4 times along chute again, and conducting pin 9 lower ends are pierced through the plug 1 (being equivalent to remove among Fig. 2 the state of solvent bottle 7) of solute bottle 14 again, under intrinsic pressure effect, medicinal liquid behind the mixing can inject infusion bottle, finishes a feeding operations to infusion bottle, and can guarantee to mix medicine and the dosing process is all carried out under aseptic strong attitude.

The effect of said chute 4 and card button 3 be when card button 3 when chute 4 moves to draw-in groove 16 places, as long as with interior cover 8 to the clockwise direction twisting, make card button 3 enter draw-in groove 16 places, can make solvent bottle 7 and solute bottle 14 maintenance conducting states.Certainly, also can not establish chute 4, draw-in groove 16 and card button 3,, also can make solvent bottle 7 and solute bottle 14 keep conducting state, unclamp hands and just can make conducting pin 9 break away from plug 1 as long as live solvent bottle 7 or interior cover 8 with hand.Said elastomer 11 is spring or the body made by gum elastic.

Cover 8 structures that can also make as Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10 in said, the probability that promptly has multiple structure to implement.
