Sterile dispensing transfusion device and the infusion method that makes up a prescriptionTechnical field
The present invention relates to area of medical devices, more particularly to a kind of sterile dispensing transfusion device.
Background technology
It is that a small amount of liquid is aspirated using disposable syringe both at home and abroad to the dosage of infusion fluid in existing medical treatmentInjection is contained in powder injection medicine bottle, is treated that medicinal powder fully dissolves and is then injected into again with syringe pumpback in liquid bottles.The above method is depositedIn following deficiency：One, drug waste, because syringe can only extract a small amount of liquid, contain the inner space of powder injection medicine bottleAlso very little, seldom liquid (usual 2-3ml) can only be injected every time and goes to dissolve medicinal powder, the decoction of such high concentration is even in medicine bottleSeldom (0.2-0.3ml) more drug waste is also had with being remained in syringe.So current dosage can typically be madeInto about 10% drug waste.Secondly, process it is cumbersome, need to first use syringe pumping liquid → injection medicine bottle (such as medicine bottle during with liquidIt is middle generation malleation also need to be vented) → extract syringe → shake medicine bottle treat medicinal powder dissolving → with syringe again pumpback powder-injection dissolveLiquid (negative pressure is produced in such as medicine bottle also to be needed to inject gas) → finally inject in liquid bottles.If need to configure in one group of liquid more orA variety of medicines, said process just need to repeat；If the slower time of compounding of medicinal powder dissolution velocity also will be longer.Thirdly, holdEasily pollution, due to being repeated exposure to syringe needle during liquid in air and puncturing medicine bottle and liquid bottles bottle stopper, bottle stopper canEnergy meeting exfoliation, is possible to also to inject gas, liquid is contaminated chance and increased in addition.The four, note that traditional dispensing method usesVolume device is disposable, and waste of material is more.
The content of the invention
It is an object of the invention to provide a kind of sterile dispensing transfusion device, to solve above-mentioned technical problem.
The technical problems to be solved by the invention are realized using following technical scheme：
Sterile dispensing transfusion device, it is characterised in that：It is made up of tube assembly of making up a prescription, air inlet tube assembly and infusion tube set, instituteState tube assembly of making up a prescription to be made up of the flexible pipe that makes up a prescription, the first puncture needle body and the second puncture needle body, described first pierces through needle body, the second thornBody of threading a needle is connected to the both ends for the flexible pipe that makes up a prescription；The air inlet tube assembly is by air induction hose and is connected to air induction hose one endFilter is formed；The infusion tube set by infusion tube, be connected to the transfusion needle body of infusion tube one end, be arranged on transfusion it is softAdjuster and drop cylinder on pipe are formed.
When making up a prescription, the first of tube assembly of making up a prescription pierces through needle body insertion infusion bottle, the second puncture needle body insertion medicine bottle, with pencilThe flexible pipe stage casing connection peristaltic pump that makes up a prescription of component.
During transfusion, the first puncture needle body and the second puncture needle body insert infusion bottle, the second puncture needle body and the flexible pipe that makes up a prescriptionDisconnect, and the open end for the flexible pipe that makes up a prescription is connected with infusion tube set, and the second puncture needle body is connected with air inlet tube assembly.
Preferably, the flexible pipe that makes up a prescription uses plastic hose.
Preferably, the flexible pipe that makes up a prescription uses rubber hose.
Preferably, the flexible pipe that makes up a prescription uses phase same material with traditional Murphy's burette, and there is same inner diameter, make up a prescription softThe wall thickness of pipe is more than the wall thickness of Murphy's burette；The flexible pipe that allows to make up a prescription substitutes traditional silicone tube and used on peristaltic pump, reducesMake up a prescription cost.
A kind of infusion method that makes up a prescription carried out using above-mentioned dispensing infusion apparatus, it is characterised in that comprise the following steps：
Make up a prescription step,
When making up a prescription, needle body insertion infusion bottle, the second puncture needle body insertion medicine bottle are pierced through by the first of tube assembly of making up a prescription, will be matched somebody with somebodyThe flexible pipe stage casing connection peristaltic pump that makes up a prescription of pencil component, infusion bottle are inverted, open and control peristaltic pump by one in infusion bottleSpray pump is divided to enter in medicine bottle, after the medicinal powder in medicine bottle is completely dissolved by decoction, then the decoction for controlling peristaltic pump to be dissolved in medicine bottleIt is pumped into infusion bottle, completes step of making up a prescription；
Temporary step,
After completion is made up a prescription, the second puncture needle body is extracted from medicine bottle, and is inserted on infusion bottle, make the decoction of preparation withExternal environment is isolated, you can temporary and transhipment；
Transfusion step,
During transfusion, first disconnected from the junction of make up a prescription flexible pipe and the second puncture needle body, then one end that infusion tube is disconnectedIt is connected, the second puncture needle body is connected with air inlet tube assembly, infusion bottle is inverted and can carried out with the infusion tube for tube assembly of making up a prescriptionTransfusion.
Make up a prescription in tube assembly, air inlet tube assembly and infusion tube set, the connected mode between each several part preferably uses RuleJoint (interface) is attached, so that connection procedure reaches the purpose of simple and fast.
The beneficial effects of the invention are as follows：
The device of the present invention is to make up a prescription to use with combined infusion, saves cost, process of making up a prescription is simple and convenient, it is not necessary to anti-The rubber stopper of infusion bottle or medicine bottle is pierced through again, avoids producing exfoliation pollution decoction；Carry out, avoid under enclosed environment during making up a prescriptionBy air pollution.
Tube assembly of making up a prescription uses during making up a prescription, and is also used in infusion process, saves consumptive material, reduces and pierces through rubberThe number of plug, reduce the possibility of liquid medicine contamination.
After the completion of making up a prescription, infusion bottle is shifted, decoction is still in closed state.
Tube assembly of making up a prescription, air inlet tube assembly and infusion tube set independent packaging in the application, wherein, made up a prescription tube assembly bothUse when making up a prescription, also used in transfusion；Air inlet tube assembly uses for selection, and infusion bottle uses when infusing, infusion bag transfusionWhen without using.
