Abstract

The utility model relates to a flexible package medicine dispensing transfusion ware, which is characterized in that the transfusion ware is divided into an upper part and a lower part. The upper part consists of a fluid single channel bottle top inserting needle, an upper transfusion tube, an air filter, a liquid-air double channel diversion dispensing needle, with the medicine dispensing function; the lower part consists of a clip type connector, a Murphy's dropper, a lower transfusion tube, a flow rate controller, a three-way pipe, a liquid filter, and a scalp needle, the liquid-air double channel diversion dispensing needle is taken off, the upper part and the lower part form an integral transfusion device through the clip type connector for the vein transfusion, the vein injection and the alternation transfusion. The arrangement of the three-way pipe can ensure that the minute bubbles is avoided from entering into the blood vessel due to the separation of transfusion device and scalp needle during the vein transfusion, thus increasing the medical safety, and being favorable for the administrate when the severe patient is salvaged. The transfusion ware can replace the injector dispensing, the energy source is saved, the transfusion corpuscle quantity caused by the repeated puncture during the dispensing process is reduced, the iatrogenic pollution is reduced, and the operation is simple.

Description

The flexible package dispensing infusion apparatus

Affiliated technical field

This utility model relates to a kind of medical apparatus, specifically a kind of flexible package dispensing infusion apparatus.

Background technology

As everyone knows, the disposable transfusion device that uses in the clinical vein transfusion in finishing the venous transfusion process, generally will use the syringe pump preparating liquid earlier in fluid bag at present, re-uses disposable transfusion device and carries out venous transfusion.Therefore there is following shortcoming:

1, transfusion device function singleness can only be infused, and can not make up a prescription.

2, pollute the probability height in the medicinal liquid process for preparation, when especially preparing bottled medicine powder, need from fluid bag, extract certain amount of fluid as solvent, be poured into molten medicine in the medicine bottle, be subjected to the restriction of syringe capacity, often need in sterile liquid, to insert repeatedly and extract liquid, easily cause the increase of liquid contamination and transfusion particle.

3, existing disposable transfusion device needs liquid filter is separated with the scalp needle handle when carrying out interim intravenous injection administration, easily pollutes and air inlet filtered during the quiet notes of medicinal liquid during operation.

Summary of the invention

In order to overcome the deficiency in the above infusion process, this utility model provides a kind of transfusion device that is exclusively used in the big liquid transfusion of flexible package and the function one of making up a prescription, reduce to greatest extent in the process of making up a prescription liquid medicine contamination and to the consumption of syringe.

The technical scheme that its technical problem that solves this utility model adopts is: dispensing infusion apparatus is established a cassette joint in the Murphy's burette upper end, be divided into upper and lower two parts with this.Top is made of liquid single channel bottleneck contact pin, upper tubing, air filter, liquid edema caused by disorder of QI flow structure syringe needle, is used to make up a prescription.Remove make up a prescription syringe needle up and down two parts inlay the complete transfusion device of airtight formation one cover by the cassette joint and be used for venous transfusion; Threeway is located at down the tube for transfusion end and directly links to each other with liquid filter, and its function one is the intravenous injection that is used for infusion process, and the 2nd, be used for two or more liquid alternated transfusions.

The beneficial effects of the utility model are, have replaced syringe and have made up a prescription, and have saved raw material; Reduce in the process of making up a prescription puncture time in sterile liquid, reduced transfusion particle and iatrogenic pollution; Transfusion device entered human vas with minute bubbles due to scalp acupuncture separates when the intravenous injection medicinal liquid had been avoided in the setting of threeway, had increased medical safety, the medication when being convenient to rescue the critical patient.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified

Fig. 1 is this utility model embodiment sketch map

Fig. 2 is this utility model dispenser preparation closure bottled medicinal liquor sketch map

Fig. 3 is that this utility model dispenser is prepared open ampoule medicinal liquid sketch map

Among the figure 1, liquid single channel bottleneck contact pin, 2, upper tubing, 3, air filter, 4, liquid edema caused by disorder of QI flow structure make up a prescription syringe needle, 5, cassette joint, 6, Murphy's burette, 7, tube for transfusion, 8, flow controller, 9, threeway, 10, liquid filter, 11, scalp acupuncture, 12, the big liquid of flexible package, 13, closure phial, 14, open ampoule down.

The specific embodiment

In Fig. 1, the syringe needle 4 that will make up a prescription is connected with upper tubing 2, together with bottleneck contact pin 1, air filter 3 common formation dispenser, is used for preparating liquid; Remove the syringe needle 4 that makes up a prescription, upper tubing 2 is connected with cassette joint 5,, be used for venous transfusion with Murphy's burette 6, following tube for transfusion 7, flow controller 8, threeway 9, liquid filter 10, scalp acupuncture 11 common formation intravenous transfusion devices.When needing intravenous drug if any change of illness state in the infusion process, close flow controller 8 earlier, syringe is thrust in the threeway 9 directly inject; When needing the two or more medicinal liquid of drop, insert threeway 9 equally and finish.

In Fig. 2, bottleneck contact pin 1 is inserted in flexible package liquid bag 12 bottlenecks, the syringe needle 4 that will make up a prescription again inserts in the closure phial 13, when phial 13 is lower than flexible package liquid bag 12 on the plane, liquid just passes through upper tubing 2, dispensing needle 4 under the effect of liquid pressure and atmospheric pressure fluid passage flows in the phial 13, gas in the phial 13 is discharged by the air flue of dispensing needle 4, after treating medicine dissolution, when raising phial 13 and promptly being higher than the planar flexible package liquid bag 12 of table, the medicinal liquids in the phial 13 flow in the flexible package liquid bag 12 smoothly.

In Fig. 3, bottleneck contact pin 1 is inserted in flexible package 12 bottlenecks, the syringe needle 4 that will make up a prescription again inserts in the open ampoule 14, be lower than a plane when loweing ampoule, liquid just under liquid pressure and atmospheric effect to outflow, when the upper tubing full of liquid, raise ampoule and dispensing needle immediately, medicinal liquid flows in the flexible package liquid bag by siphon principle.
