Parenteral nutrient solution preparation device and preparation method thereof

Abstract

The invention belongs to the technical field of nutrient solution preparation, and particularly relates to a parenteral nutrient solution preparation device and a preparation method thereof. The device comprises an outer cylinder and an injection module, the injection module is clamped to the top of the outer cylinder, and a second protective cover is fixedly connected to the outer side of the outer cylinder; in the present invention, a first fan-shaped cavity, a second fan-shaped cavity and a third fan-shaped cavity are formed in the top of a mixing module; different kinds of liquid are respectively injected into the three fan-shaped cavities through the injection pipes; then, the mixed liquid is introduced into the mixing module to be stirred; the relative positions of a first-stage mixing cylinder, a second-stage mixing cylinder, a third-stage mixing cylinder and a fourth-stage mixing cylinder are adjusted through the output end of an electric push rod, the mixing uniformity degreeof nutrient solutions in the mixing module can be improved, redundant air in the mixing module can be exhausted according to the preparation amount of the nutrient solutions, the probability that impurities in the air pollute the nutrient solutions is reduced, and the preparation quality of the nutrient solutions is improved.

Description

technical field [0001] The invention relates to the technical field of nutrient solution configuration, in particular to a parenteral nutrient solution preparation device and a configuration method thereof. Background technique [0002] Total parenteral nutrition solution is injected into the patient's blood circulation through a route other than the gastrointestinal tract, that is, intravenously. The nutrient solution includes all the nutrients and rich heat energy required by the patient. Because the parenteral nutrition solution needs to be used within 48 hours after preparation, the parenteral nutrition solution is mostly prepared when needed, and the storage time cannot exceed 48 hours. If the storage time is long, the stability of the fat emulsion will be lost, and it is easy to produce The phenomenon of water and oil separation cannot be infused. Take it out 1-2 hours before use and place it at room temperature, and infuse it after rewarming. [0003] However, becau...

Problems solved by technology

[0003] However, because the amount of parenteral nutrition solution to be used in different time periods is uncertain, it needs to be configured according to the specific needs of patients. When there are a large number of patients who need to use parenteral nutrition solution, the traditional single configuration The method cannot
