Description

DESCRIPTION Intelligent dispensing device

TECHNICAL FIELD The invention relates to the technical field of medical devices, in particular to an intelligent dispensing device.

BACKGROUND In clinical treatment, it is often necessary to mix different drugs according to a certain proportion and order. For example, for children, the medication for children is different from that for adults, and most of the drug doses are determined according to the weight of children; There is a high demand for dose accuracy, and most drugs can't be used in whole bottles. For example, in pediatric clinical intravenous high nutrient solution, the basic composition of intravenous nutrient solution includes various nutrients such as fat milk, amino acids, glucose, vitamins, electrolytes and trace elements. The stability of all-in-one nutrient solution is affected by pH value, amino acid concentration, glucose concentration, electrolyte concentration, fatty acid types and other factors affecting lipid peroxidation of fat milk, and even the container materials, light, oxygen, temperature, storage time and preparation methods (especially the mixing order of various nutrient solutions) which are in direct contact will have an impact on the stability of nutrient solution.

At present, the method of preparing nutrient solution in clinic mainly uses empty needles with different volumes, such as 50ml and 20ml, to manually extract various nutrient solutions and mix them together in a certain order and quantity. The specific order is as follows: (1) Phosphate and insulin are added to glucose (in pediatric ward, because children are young and need to leave room for the nutrients mixed in later, the required liquid quantity will not be a whole bag of sugar water, and the whole bag of liquid needs to be manually pumped away with 50ml empty needles. (2) Phosphate-free electrolyte and trace elements are added to amino acids, and then the amino acids are pumped into liquid (1) with a 50ml empty needle and mixed evenly (because the available empty needle with the largest volume is 50ml at present, when the dosage of older children is more than 50 ml, it needs to be pumped and injected into liquid (1) repeatedly; In addition, the types of amino acids 18AA and 9AA commonly used in clinic are all 250ml/ bottle. According to the body weight of children in most ages, the one-time consumption of amino acids is mostly < 250ml, so it is necessary to use 50ml empty needles to manually suck off the surplus amino acids in the bottle before adding phosphate-free electrolytes and trace elements to the amino acids); (3) Add fat-soluble vitamins and water-soluble vitamins into fat emulsion, then extract fat emulsion with 50ml empty needle, and inject it into liquid (2) to mix evenly (The specifications of fat milk commonly used in clinic are mostly 250ml/ bottle. Most of the time, children can't use a whole bottle in a single dose. It is also necessary to use 50ml empty needle to suck off excess fat milk before fat-soluble vitamins and water-soluble vitamins can be added to fat emulsion).

In the above operation process, the empty needle can only pump the liquid once, but cannot transfer the liquid directly from one container to another, so it needs to pump and inject the liquid into another container repeatedly, and there are many inconveniences and potential risks in multiple pumping.

(1) Repeated aspiration can easily lead to empty needles and suspicious contamination of nutrients, resulting in contamination of nutrient solution, increasing the safety risks of medication for patients and even bringing serious adverse reactions such as bloodstream infections to patients.

(2) Repeated puncture of the liquid bag by the empty needle can easily make the liquid bag form a small plug, and form foreign matter into the nutrient solution, which is harmful to the body.

(3) Repeated suction takes a long time, which makes the preparation time of nutrient solution too long and affects the stability of nutrient solution; (4) Repeated suction is very easy to make the empty needle blunt, making suction resistance increased, so need to be diligent replacement. This leads to a large amount of empty needles, high cost of empty needle supplies, and repeated suctioning makes nurses' hands painful and calloused,; (5) Repeated suction requires repeated puncture of the liquid bag, the liquid is easy to spill from the tip of the needle, resulting in glove contamination which will destroy the sterile surface, resulting in contamination, and the configuration process requires the replacement of sterile gloves from time to time, both delaying time and increasing the amount of gloves.

(6) Repeated suction is time-consuming and laborious, which reduces the work efficiency of nurses.

SUMMARY The purpose of the present invention is to provide an intelligent dispensing device, which can realize the electric dispensing of pharmaceutical solutions containing multiple ingredients in a certain sequence and proportion, which can replace the current manual,
