Description
Technical field
The present invention relates to field of medical device, in particular to dispensation apparatus and method.
Background technique
It is in the prior art make up a prescription mostly use it is artificial extract liquid and be injected into medicine bottle-and rock medicine bottle-draw back mixed liquor
Method carries out, and has dispensing efficiency low or medical fluid mixes/dissolve non-uniform problem.
Also there is the scheme using semi-automatic dispensing machine, such as can be realized and rock acceleration mixing/dissolution equipment, however exist
The problem of inconvenient, inefficiency.
Summary of the invention
The present invention is intended to provide dispensation apparatus, to solve dosage in the prior art, there are dispensing efficiency is low or medical fluid
The problem of mixing/dissolution.
Another object of the present invention is to provide the dosages based on above-mentioned dispensation apparatus.
The embodiment of the present invention is achieved in that
A kind of dispensation apparatus, for carrying out mixed configuration to the liquid in the drug and liquid bottles in medicine bottle comprising: pipe
Needle assemblies comprising pipeline, one end connecting puncture needle of pipeline, the other end connect needle；The pipeline is configured to
Two-way flow under the driving of peristaltic pump；The puncture needle includes puncturing head and lengthening needle；Described in one end connection of the puncture needle
Pipeline, the other end for lengthening needle insertion puncturing head are simultaneously connected to by puncture needle with pipeline；The puncturing head is also provided with row
Gas channel, and when puncture needle is inserted into liquid bottles, the open at one end of exhaust passage is located in liquid bottles, and another end opening is located at
Outside liquid bottles.
In present embodiment, medical fluid can be driven to flow forward or backwards by peristaltic pump, allow liquid sufficiently and medicine
Object mixing/dissolution, the beneficial effect high with dispensing efficiency, effect of making up a prescription is good.
Optionally: the drug is liquid drug, and medicine bottle used is just set, and the needle is configured to insertion liquid medicine
The bottom of object, the end of the lengthening needle of the puncture needle are located at the bottom of the liquid of liquid bottles.
Optionally: the drug is medicine powder；The pin hole of the needle is opened in the side wall of needle, and pin hole institute
Make in the position on needle side when needle is inserted into medicine bottle, pin hole is located at the inside of the medicine powder in medicine bottle.For
Medicine powder, to avoid liquid from entering from the upper surface of medicine powder and may form condensed layer barrier liquid under with medicine powder
The contact of layer medicine powder, influences mixing/dissolution, pin hole is located at the interior of medicine powder in a state of use in present embodiment
Side so that liquid directly from the inside of medicine powder project, certain impact is formed to medicine powder, can faster and better and
Medicine powder combination mixing/dissolution.
Optionally: the needle has limiting section, and during the needle is inserted into medicine bottle, limiting section is hindered by medicine bottle
Gear, to limit continuing into for needle；In the state that needle is inserted into limiting section and is stopped by medicine bottle, the pin hole is located at medicine bottle
The inside of interior medicine powder；The limiting section is served as by the tip of the needle, and is formed and limited with the bottom of bottle of medicine bottle；Or
The limiting section is formed with the bottleneck of medicine bottle and is limited by serving as from the protrusion that needle outer peripheral surface extends to form outward.For side
Just control of the user to pin hole position, in present embodiment, by the setting of limiting section, so that user directly inserts needle
Enter the bosom that can be arrived, that is, can ensure that pin hole is located inside medicine powder, it is easy to operate.
