Abstract
An infusion dosage instrument comprises a main machine and an accessory, wherein the main machine comprises a positive pressure source and a negative pressure source, and the accessory comprises a sharp-sealed porous double-channel needle 21. The utility model discloses owing to have two atmospheric pressure sources of malleation, negative pressure simultaneously, can accomplish and join in marriage the work of taking out, annotating in the liquid medicine, improve work efficiency, alleviateed intensity of labour, because seal the porous binary channels needle point of point and do not have a mouthful, during the cutting bottle plug, can not cause the micelle to pollute the liquid medicine. The utility model has simple and reasonable structure, convenient use and easy popularization.
Description
This utility model relates to medical equipment, particularly a kind of infusion instrument.
There is the deficiency of two aspects in electronic infusion instrument of the prior art, and the one, only there is the negative pressure gas circuit, be applicable to the medicinal liquid of oneself dilution of suction, be not suitable for and make up a prescription; The one, syringe needle can cut plug in use, has increased the microgranule in the medicinal liquid.
The purpose of this utility model can be finished the water filling of infusion in that a kind of band positive and negative pressure gas circuit is provided, and inhales the medicine overall process, has the germ contamination that solves in the process of making up a prescription, the infusion instrument of problems such as plug microgranule or other particle contamination.
The purpose of this utility model is to realize by such structure: promptly this utility model comprises main frame and adnexa, and wherein main frame comprises micro air pump and the micro machine of casing and Qi Nei, and adnexa comprises conduit, filter and pin insert; Of the present utility model being characterised in that: the malleation air-flow end of micro air pump and negative-pressure air-flow end are formed the positive and negative pressure source by pressure regulator valve and surge flask and conduit respectively, and the positive and negative pressure output interface is arranged on housing; Also comprise disposable bags, the sharp porous dual pathways pin of envelope in the adnexa, after wherein the malleation output interface is connected filter, airbag by conduit, be connected with infusion bottle by pin insert; Infusion bottle is by conduit and seal sharp porous dual pathways pin insert and be connected with medicine bottle.
Said structure of the present utility model can further specify by accompanying drawing.
This utility model has following accompanying drawing:
Accompanying drawing 1 is this utility model structure principle chart;
Accompanying drawing 2 is this utility model main frame external structure;
Accompanying drawing 3 is an airbag sketch map of the present utility model;
Accompanying drawing 4～accompanying drawing 6 is the sharp porous dual pathways needle construction sketch map of envelope.
Referring to accompanying drawing 1, this utility model is by micromachine 1, the miniature no oil gas pump 2 of driving, pressure regulator valve 3,4, compositions such as surge flask 5,6 and conduit.Wherein the malleation air-flow end of micro air pump 2 and negative-pressure air-flow end constitute malleation, negative pressure source by pressure regulator valve, surge flask and conduit respectively.Positive pressure gas stream enters infusion bottle C by surge flask 5, malleation output interface A, conduit C, air filter 9, airbag 11, pressure in the bottle is increased, by conduit and seal the sharp porous dual pathways pin 12A liquid is pressed into the phial that fills powdery or other shape medicine, liquid is mixed with medicine; The negative pressure gas-liquid makes infusion bottle C be the vacuum shape by surge flask 6, conduit, negative pressure output interface B, and the medicinal liquid that has diluted is drawn back in the infusion bottle by sealing sharp porous dual pathways pin 12B.Control valve 3,4 is controlled the size of positive and negative pressure respectively.
Referring to accompanying drawing 2, this utility model is a metal shell, and loam cake is a movable tray 7, is used for indispensable apparatus of splendid attire and medicine; The side of casing is equipped with Removable hook frame 8 and infusion bottle frame 10 for sleeping in.This outdoor main unit also has manual power switch 12 and foot-operated on and off switch 13.
Referring to Fig. 3, the air inlet termination air filter 9 of airbag 11 has actuator to be connected with infusion bottle by syringe needle on the pipeline of outlet side.
Referring to Fig. 4～6 envelopes point porous dual pathways pin 12 is the dual pathways, and a passage is communicated with tube for transfusion, and another passage is communicated with exhaustor, and the needle point of pin seals, and through hole is opened on sidewall.Wherein, be used for the envelope point porous dual pathways pin 12A of positive pressure source, because it finishes the function of liquid being injected phial, thereby the position in the hole on the sidewall of the pipeline that is communicated with tube for transfusion is higher than the position in the hole on the sidewall of the pipeline that is communicated with exhaustor.And be used for the envelope point porous dual pathways pin 12B of negative pressure source part, because finishing, it will dilute the function that good medicinal liquid is extracted out in the phial, therefore the position in the hole on the sidewall of its pipeline that is communicated with tube for transfusion is lower than the position in the hole on the sidewall of the pipeline that is communicated with exhaustor, so that the medicinal liquid in the bottle is drained only.In addition, the described dual pathways can disjunctor, also can separate.
Compare with prior art, the utlity model has following obvious advantage and characteristics:
1, has simultaneously malleation, two pneumatic supplies of negative pressure, automatically finish vehicle In take out, notes work, can increase work efficiency, reduce labor intensity.
2, the sharp porous binary channels pin of envelope is not because needle point has mouth, during the cutting plug, no Can cause the plug particulate, be designed with air cleaner etc. in addition, can guarantee air-flow and Liquid asepsis is not contaminated.
3, since originally the instrument that makes up a prescription be a closed system, during preparation chemotherapy medicinal liquid, let out fullly as long as medicine just can not take place in proper operation, can protect the personnel health in the protection zone.
4, this apparatus structure is small and exquisite, simple, and stable mechanical performance is furnished with pallet, " two ", foot switch on the casing, and is rational in infrastructure, supporting with disposable attachment, easy for operation, laborsaving, saving time is easy to popularize and promotes.
