Blending device for parenteral nutrient solution

Abstract

The invention relates to a parenteral nutrient solution blending device which effectively solves the problems that in the existing intensive care process, a parenteral nutrient solution bag is frequently taken down, shaken and shaken evenly and then hung on an infusion support, operation of medical staff is tedious, and efficiency is low. According to the technical scheme, the liquid storage bag comprises a Y-shaped liquid storage bag body, a first air cylinder is arranged above the liquid storage bag body, two crossed second air cylinders are arranged at the lower end of the first air cylinder, a second piston rod is arranged in each air cylinder, a rotating shaft is rotationally installed at the outer end of each second piston rod, and a coil spring capable of resetting the rotating shaft is arranged on each rotating shaft. A first reel is fixed to one end of the rotating shaft, second reels are fixed to the other end of the rotating shaft, the diameter of the first reel is larger than that of the second reel, a first rope is wound and fixed to the first reel, the free end of the first rope is fixed to the upper half portion of the liquid storage bag on the corresponding side, and a second rope is wound and fixed to each second reel. The free ends of the second ropes are fixed to cylinder barrels of the corresponding second air cylinders.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a parenteral nutrition solution mixing device. Background technique [0002] Parenteral nutrition (PN) refers to the provision of nutrients through blood circulation through veins. Parenteral nutrition is of great significance. When the gastrointestinal function is seriously impaired, parenteral nutrition can provide the nutrients needed by the body and promote recovery. [0003] Parenteral nutrition solutions require: [0004] Not fast, not slow, not hot, not suitable, the nutrient solution should be dripped at a uniform speed as much as possible, the infusion time should be at least 12 hours, and the drip rate should be controlled at 40-60 drops / min. If the drip rate is too fast, nausea and vomiting may occur , sweating, can also cause complications such as elevated blood sugar, insulin resistance, and phlebitis. Since the osmotic concentration of parenteral nutrition solution...
