Automated dispensing can be achieved, and reduce the chance of the waste and drug contamination of drug to greatest extent, but the device dispensing needle and master
Machine is complicated, and palpus manual palpation controls host switch, on the one hand increases nurse's operation by human hand burden, on the other hand be easy to cause
Hand contamination, as can simplifying the structure and dosage of dispensing needle, host, liberation operator's both hands are only used for puncture procedure, keep away
Exempt from hand and be in direct contact that host is contaminated, will better meet hospital rapid, high volume is concentrated to make up a prescription needs with making up a prescription for sterile purification
It asks.
Invention content
The purpose of the present invention is to provide a kind of easy to operate and can reduce the round-trip drawing-in type of foot-operated control of hand contamination
Dispensation apparatus and dosage for powder-injection.
The technical solution that the present invention takes is：The present apparatus by host, pedal control switch and special dispensation needle (hereinafter referred to as
Dispensing needle) constitute, host mainly by motor, control circuit board and can the pump head of positive and negative wriggling form, pedal control switch is
The two-way positive and negative wriggling for controlling host pump head, dispensing needle are made of the wriggling hose that both ends are piercing needle.Foot is stepped on foot-operated
The right switch of switch is controlled, host pump head forward direction wriggling dispensing needle wriggling hose is waited in the liquid injection medicine bottle in fluid bag
After medicinal powder dissolving, foot steps on the left-handed opening of pedal control switch, host pump head reversely wriggling dispensing needle wriggling hose by medicine in medicine bottle
It can be completed and make up a prescription in liquid resorption to fluid bag.This dispensation apparatus dispensing needle is only made of wriggling hose and piercing needle, structure
Simply, cost can substantially reduce, convenient for disposable；Foot steps on pedal control switch and the forward and reverse compacted of host pump head can be realized
Liquid transfer dynamic and between fluid bag and medicine bottle, completes overall process of making up a prescription；Operator's both hands, which only need constantly to puncture, replaces medicine bottle i.e.
Dispensing operation can be carried out continuously.The present apparatus is greatly improved dispensing efficiency and speed by the dosage used both hands and feet, and reduces
Hand is especially suitable for the demand of making up a prescription that hospital concentrates rapid, high volume to make up a prescription with sterile purification by outside contamination.
The present invention is further discussed below below in conjunction with the accompanying drawings：

Specific embodiment
Fig. 1, Fig. 2 are a kind of existing dispensation apparatus schematic diagram for powder-injection, and medicine bottle is established by binary channels dispensing needle
With the unicom of fluid bag, fluid bag (B) is injected into dispensing needle one end when making up a prescription, one end is injected medicine bottle (b) and held, fluid bag when beginning
(B) upper, medicine bottle (b) under, host driven hose make the liquid in fluid bag (B) by more complex binary channels dispensing needle into
Enter medicine bottle (b) end, be manually pressed by host switch, the overturning of host pump head makes fluid bag (B) under, medicine bottle (b) is in upper, medicine bottle (b)
It completes to make up a prescription in interior liquid resorption to fluid bag (B).The dispensation apparatus and make up a prescription that process is complex, and dispensing needle is binary channels
Structure leads to dispensing needle palpus larger diameter, punctures more difficult when fluid bag (B) and medicine bottle (b) bottle stopper.
Fig. 3 is dispensing needle schematic diagram of the present invention, and dispensing needle (3) is single channel, by wriggling hose (3B) and piercing needle
(3A) is formed, and simple in structure to substantially reduce cost, piercing needle (3A) is relatively thin convenient for puncturing, and is suitable for disposable.
Fig. 4 is fluid present invention forward direction suction operation schematic diagram, this device is by host (1), dispensing needle (3) and foot-operated control
(4) composition is switched, regulating and controlling host pump head (2) forward and reverse wriggling dispensing needle (3) hose (3B) by pedal control switch (4) can be complete
At the transfer of liquid.When making up a prescription, first the wriggling hose (3B) of dispensing needle (3) is mounted in host (1) pump head (2), then will match
The piercing needle (3A) of medicine needle (3) is inserted into fluid bag (B) and powder injection medicine bottle (b) end respectively, and foot steps on foot-operated right switch (4A), main
