Abstract
The utility model relates to a medicine adding-in device for infusion, which solves the problems that hands fatigue and are easy to touch a needle bolt of an injector to pollute medicine when infusion physic liquor is prepared in a manual suction mode, a needle head punctures a bottle cork for many times, which causes debris to be fallen into an infusion bottle to pollute medicine. The utility model is characterized in that the tail part of a liquid suction needle is connected with a pipette, and the other end of the pipette is provided with a liquid outlet needle. The utility model is also provided with an air suction needle, and the tail part of the air suction needle is connected with an air suction tube. The utility model can be widely used for preparing various infusion medicines.
Description
This utility model relates to a kind of medical dispensing appliance, particularly a kind of transfusion drug feeding device.
The nursing staff at first will make up a prescription before to patient's transfusion, promptly adds medicine in infusion bottle.Existing adding method thereof is with the medicine in syringe pump ampoule or the medicine bottle, injects in the infusion bottle then.There are following three problems in the method for this dosing: the one, and the nursing staff is mechanically suction repeatedly, easily makes hand fatigue; The 2nd, during suction, nursing staff's hand easily touches the pintle part, causes medicine pollution, and when adding multiple medicine, the chance of pollution is more especially; The 3rd, the bottle closure of rubber of syringe needle repeated localised puncture infusion bottle enters in the infusion bottle tiny scrap gum and also can pollute medicine, brings infringement to the patient.
The purpose of this utility model provides a kind of dosing apparatus that uses vacuum extractor to replace artificial suction.
This utility model is achieved in that a kind of transfusion drug feeding device, and it has aspirating needle, and its feature is that the afterbody at aspirating needle is connected to pipette, at the other end of pipette the fluid pin is housed; It also has an air-breathing pin, is connected to suction nozzle at the afterbody of air-breathing pin.
For easy to use, fluid pin and air-breathing pin can be made of one, but they are not connected, in their outside baffle plate are arranged, so that when inserting infusion bottle, can grasp the degree of depth of insertion, and the head of air-breathing pin to the distance of baffle plate less than the head of fluid pin distance to baffle plate.
In addition, be inhaled in the infusion bottle, in pipette, be equipped with and filter sponge for preventing the chip in the ampoule.
When needs make up a prescription, fluid pin and air-breathing pin to be inserted in the infusion bottle, air-breathing needle section will be higher than liquid level, and aspirating needle inserts in the medicinal liquid ampoule of desire suction, and the vacuum extractor of using in suction nozzle and the hospital is joined.After starting vacuum extractor, form negative pressure in the infusion bottle, the medicinal liquid in the ampoule will flow in the infusion bottle automatically.As be circumscribed with an air accumulator at vacuum extractor, then suction nozzle and air accumulator join, and a vacuum extractor can make up a prescription simultaneously for a plurality of nurses so.Utilize this transfusion drug feeding device to make up a prescription, thereby owing to utilize vacuum extractor to replace artificial suction to remove the problem of nurse's hand fatigue, also improved work efficiency, it has also avoided nurse's hand to touch the problem that the syringe pintle pollutes medicine simultaneously.When needs add multiple medicine, fluid pin and air-breathing pin need not be extracted, the ampoule that only needs aspirating needle to be put into successively each medicinal liquid gets final product.So it has also reduced because of repeatedly the puncture rubber stopper of infusion bottle of syringe needle enters in the infusion bottle chip, causes the problem of medicine pollution.This utility model can be widely used in the various infusion medicines of preparation.
Accompanying drawing is a structure chart of the present utility model.
Below in conjunction with accompanying drawing this utility model is described in detail.
Find out from accompanying drawing, be with needle guard 2 on the aspirating needle 1, be connected to pipette 3 at the afterbody of aspirating needle.Be equipped with one in the pipette 3 and filter sponge 4, the afterbody of the other end of pipette 3 and fluid pin 5 joins.The afterbody of air-breathing pin 6 is connected to suction nozzle 7, and the other end of suction nozzle 7 can communicate with vacuum extractor or the air accumulator that communicates with vacuum extractor.Fluid pin 5 is to be made by duroplasts with air-breathing pin 6, and they make one, but not connected, in their outside baffle plate 8 are arranged.As can be seen, the distance of fluid pin 5 heads and baffle plate 8 is greater than the distance of air-breathing pin 6 heads and baffle plate 8 from the figure.
