Abstract

The utility model provides a liquid injection medicine dispensing device driven by a peristaltic pump. The device is rapid to use, efficient, safe and aseptic. The device is composed of a puncture needle (1), a filter (2), a hose (3), a sucker (5) and the like. The puncture needle (1), the filter (2), the hose (3), the sucker (5) and the like are connected in series to form a liquid medicine transfer channel. When the liquid injection medicine dispensing device is used, the puncture needle (1) penetrates into a bottle plug to be inserted into a liquid bottle (7), the hose (3) is made of elastic materials and is placed into the peristaltic pump (4), the peristaltic pump (4) squeezes the hose (3) in a peristaltic mode so that suction force can be generated inside the cavity of the hose (3), the sucker (5) is thin and long, the end (rather that the slope face or the side face) of the sucker is open, the sucker (5) can reach the bottom of a small glass ampoule (6) to thoroughly suck the liquid medicine, the sucker (5) is moved, then multiple kinds of liquid medicine can be dispensed, and manual suction is not needed. The filer (2) is arranged between the puncture needle (1) and the hose (3), so that impurities such as glass disintegrating slag are prevented from entering the liquid, and aseptic operation and medicine dispensing efficiency during medicine dispensing are greatly improved.

Description

A kind of aqueous injection dispensation apparatus driving by peristaltic pump

Affiliated technical field

This utility model relates to medical instruments field, and a kind of dosing dispensation apparatus for aqueous injection medicine is provided.

Background technology

The making up a prescription to typically refer to medicinal liquid or medicated powder are transferred in liquid bottles of indication in medical treatment, for inputting in human body.Existing both at home and abroad the dosage of aqueous injection medicine is normally injected in liquid bottles with syringe pump medicinal liquid, when the method is used for preparing branched medicinal liquid, pumping efficiency is low repeatedly, easily the impurity such as glass disintegrating slag are sucked in liquid bottles, and syringe needle distal opening is generally Huo side, inclined-plane, be difficult to clean the medicinal liquid suction at the bottom of bottle.The inventor once applied for that one was made up of negative pressure generation, special puncture needle, suction pipe and defecator, make it to produce aqueous injection in certain negative pressure and then suction glass ampoule by air in pumping liquid bottle and transfer to dosage and the device in liquid bottles, limited being widely used during this device is making up a prescription owing to being difficult to form effective negative pressure in Soft Roll bottling.

Summary of the invention

The purpose of this utility model is to provide a kind of dispensation apparatus that is applicable to existing all kinds of packing liquid bottle height and imitates and have filtering function.

To achieve these goals, the technical scheme that this utility model is taked is:

A kind of dispensation apparatus of realizing described dosage: this device is made up of puncture needle, flexible pipe, suction pipe and filter etc., and said modules is connected into a medicinal liquid transfering channel.Puncture needle is similar to syringe needle and inserts liquid bottles for the bottle stopper that punctures, and between puncture needle and flexible pipe, establishes filter, and flexible pipe adopts elastomeric material, and suction pipe is elongated and be opened on terminal.When use, first puncture needle is inserted to liquid bottles through bottle stopper, then flexible pipe is inserted in peristaltic pump, in the time starting peristaltic pump, being wriggled to push with self its intracavity of elasticity because of flexible pipe to produce suction force, and suction pipe is inserted to the little ampulla inner liquid medicine of glass bottom medicinal liquid can thoroughly will be inhaled in liquid bottles; Without artificial suction, and as long as mobile suction pipe, to the glass ampoule of required dosing, can make up a prescription continuously to branched medicinal liquid; Filter can stop the impurity such as glass disintegrating slag to enter in liquid.This apparatus structure is simple, cost is controlled, can disposable use effectively improve dosing processing safety and efficiency.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further narrated:

Fig. 3 is this utility model operation principle schematic diagram

In figure: the little ampulla 7-liquid bottles of 1-puncture needle 2-filter 3-flexible pipe 4-peristaltic pump 5-suction pipe 6-glass 8-syringe

The specific embodiment

Fig. 1 is existing aqueous injection dosing method schematic diagram: with emery wheel cutting or with the top of the little ampulla 6 of ironware shattered glass (in this process glass disintegrating slag can fall into ampulla interior), from the little ampulla 6 of glass, extract again aqueous injection (being difficult to clean the medicinal liquid suction at the bottom of bottle because syringe needle end is generally inclined-plane or is opened on side) with syringe 8, then use in syringe 8 filling liquid bottles 7.The showy microgranule of the glass disintegrating slag that said process is small and air is likely sucked in filling liquid bottle 7, and input human body works the mischief; While being used for preparing branched medicinal liquid, pumping efficiency is low repeatedly.

Fig. 2 is this utility model structural representation: form medicinal liquid transfering channel by puncture needle 1, flexible pipe 3, suction pipe 5 and filter 2.Puncture needle 1 is similar to syringe needle, for piercing through liquid bottles 1 bottle stopper; Flexible pipe 3 has certain elasticity, and wriggling, intracavity under extruding can produce suction force; Suction pipe 5 is elongated and be opened on terminal, can visit and ampulla bottom more thoroughly exhaust medicinal liquid; Filter 2 is located between puncture needle 1 and flexible pipe 3, can stop the impurity such as glass disintegrating slag to enter in liquid.

Fig. 3 is this utility model operation principle schematic diagram: first puncture needle 1 is inserted to liquid bottles 7 through bottle stopper, again flexible pipe 3 (elastic material) is inserted in peristaltic pump 4, in the time starting peristaltic pump 4, being wriggled to push with self its intracavity of elasticity because of flexible pipe 3 to produce suction force; Now, suction pipe 5 is inserted to the little ampulla of glass 6 inner liquid medicine bottoms, medicinal liquid will thoroughly be sucked in liquid bottles 7 completes dosing; Without artificial suction, and as long as mobile suction pipe 5, to the glass ampoule of required dosing, can make up a prescription continuously to branched medicinal liquid; On medicinal liquid transfering channel, establish filter 2, the impurity such as glass disintegrating slag can be prevented from entering in liquid, have improved dosing processing safety and dispensing efficiency.

Claims

1. the aqueous injection dispensation apparatus driving by peristaltic pump, is characterized in that: it comprises the compositions such as puncture needle (1), filter (2), flexible pipe (3) and suction pipe (5); Puncture needle (1) is similar to syringe needle, for the liquid bottles that punctures (7) bottle stopper; Flexible pipe (3) is elastic material, and when peristaltic pump (4) is wriggled extruding to it, its intracavity produces suction force; Suction pipe (3) is elongated and be opened on terminal, can visit and the little ampulla of glass (6) bottom more thoroughly exhausts medicinal liquid, and mobile suction pipe (3) can be to branched medicinal liquid continuous sucking; Filter (2) is located between puncture needle (1) and flexible pipe (3), enters liquid for impurity such as filter glass disintegrating slags.
