Description

DETAILED DESCRIPTION OF THE INVENTION The first aspect of the present invention relates to an intravenous drip additive preparation device for preparing drip additive liquids such as various vitamins and minerals to be added to a main intravenous drip liquid such as Ringer's solution in a hospital or the like. The second invention relates to an intravenous solution preparation device for preparing an intravenous solution from a main intravenous solution and various additive solutions for intravenous drip, and the second invention relates to an intravenous solution mixing device for preparing an intravenous solution from a main intravenous solution and various additive solutions for intravenous drip, and to dramatically increase the efficiency of the mixing operation and reduce the cost of one intravenous solution. With the goal.

When administering an infusion to a patient in a hospital, one infusion of whitening Ringer's solution or physiological saline with a small amount of each of several additive solutions is instilled.

Conventionally, additive liquids were used in ampoules, so when making additions, one had to cut several ampoules of various additive liquids, hold the ampule with the left hand, and operate the syringe with the right hand, which was repeated to ensure that the inside of the syringe remained intact. This was done by having the patient inhale several types of additives and injecting them into an infusion station.

This method has the following drawbacks.

(b) Operation of cutting ampoules for a large number of ampoules.

Not only is it time-consuming to operate the syringe with the right hand and inhale through a thin needle, but the right hand is also extremely fatigued. For example, it takes one nurse 1 to 2 hours in the morning and evening to prepare IV fluid for 30 patients (approximately 150 ampoules).

(b) The additive liquid is used in ampoules, which is not only extremely expensive, but also poses a risk of contaminating glass particles when cutting the ampoules.

The present invention aims to solve the above-mentioned drawbacks, and the first invention is to supply the i4 additive solution to each of the plurality of additive solution containers containing each drip additive solution through the respective additive solution take-out passages. By communicating with the extractor and installing each additive liquid quantitative extractor in each extraction route, by operating each quantitative extractor of the extraction route for the necessary drip additive solution from the container as appropriate, each drip additive solution can be dispensed. This is a device for dispensing an infusion additive by dispensing the required amount into an additive extractor and inhaling the additive into a syringe from the liquid suction port of the additive extractor.

In addition, the second invention provides a plurality of main liquid containers that contain each of the main intravenous liquids and a plurality of additional 7JD IfL containers that contain each of the intravenous additive liquids, and a common intravenous liquid outlet through each container 2 and each outlet. The required amount of each intravenous solution can be taken out by connecting each intravenous solution with a fixed quantity dispenser in each outlet, and by operating each fixed quantity dispenser in the outlet route for taking out the necessary intravenous solution from the container as appropriate. This is a device for dispensing intravenous fluids that can be taken out to the outlet and dispensed.
