Description

Technical Field

[0001] The invention belongs to the technical field of medical trolleys, and in particular relates to an enteral nutrient solution preparation rack. Background Art

[0002] Enteral nutrition solution is a nutritional supplement designed for patients who cannot meet their nutritional needs through normal diet. It can be directly administered through nasogastric tube, gastrostomy, jejunostomy, etc., and is suitable for patients with a variety of medical conditions. Enteral nutrition solution contains comprehensive and balanced nutrients, mainly including: Carbohydrates: such as maltodextrin and fructose, providing energy sources. Protein: derived from casein, soy protein, etc., some products provide amino acids or short peptides to adapt to patients with weakened digestion and absorption capacity. Fats: such as vegetable oils (such as safflower oil, rapeseed oil) and lecithin, provide energy and essential fatty acids. Dietary fiber: such as soy polysaccharides, helps maintain intestinal health. Minerals and vitamins: supplement various trace nutrients needed by the body. Trace elements: ensure the comprehensiveness of nutrition.

[0003] Enteral nutrition solution is suitable for: digestive system dysfunction; critical illness; metabolic gastrointestinal diseases; malnutrition; during treatment of specific diseases; diabetic patients; patients who cannot or are unwilling to eat.

[0004] When using, you should follow the doctor's instructions and pay attention to the concentration and drip rate of the nutrient solution to avoid gastrointestinal reactions. In order to control the concentration of the nutrient solution, multiple nutrients need to be mixed before use and then supplied through an infusion tube. However, this method is inefficient and requires a high density of medical staff when the patient density is high. Each patient will have a large number of nutrient packs, and they need to be dispensed on the same workbench, causing confusion in dispensing, low efficiency in finding medicines, and prone to errors. Summary of the invention

[0047] The working principle of this embodiment is as follows. When the present invention is used, the medical staff puts the medicine corresponding to the patient on the surface of the mobile trolley body 1 used by the corresponding patient, and does not need to find the corresponding nutrient solution in the liquid exchange chamber when changing the liquid, thereby avoiding liquid exchange errors and improving the liquid exchange efficiency. By pulling the control handle 6, the main rotating plate 300 can be pulled out of the rotating seat 4, and the paddle 304 is pulled to align the pin 303 with the slot 302. The paddle 304 is released, so that the pin 303 is inserted into the slot 302 under the action of the compression spring 306, so that the main rotating plate 300 is relatively fixed;

[0048] Pull the control knob 322 out of the spring slot 323, so that the tension spring 324 is stretched, and the fixed protrusion 320 is pulled out of the fixed slot 319 and the linkage slot 325, and then pull the control slot 316 to pull the slave rotating plate 318 out of the groove 301 of the main rotating plate 300 and keep it in a vertical state, and release the control knob 322, so that the control knob 322 is pulled into the spring slot 323 again under the action of the tension spring 324, and the fixed protrusion 320 is inserted into the corresponding fixed slot 319 and the linkage slot 325, so that the main rotating plate 300 and the slave rotating plate 318 are relatively fixed;

[0049] The slider 313 slides under the action of the fixed spring 308, draws the elastic groove 312 for the hook 311, and then adjusts the rotating hook 317 so that the rotating hook 317 set at a right angle remains in a horizontal state, and then adjusts the rotating shaft 315 so that the rotating hook 317 can be rotated out of the receiving groove 309, and the rotating hook 317 is adjusted again so that the rotating hook 317 remains in a vertical state, and the corresponding nutrition bag can be hung at the positions of the rotating hook 317 and the hook 311;

[0050] The nutrient pack is connected to the sealing plug 3278 at the position of the liquid preparation column 3273 through an infusion pump. The speed regulator at the infusion pump adjusts the flow rate of the nutrient solution. The nutrient solution drips onto the surface of the liquid guide block 3275 and flows to the liquid guide groove 3272 of the liquid preparation disk 3271, so that multiple nutrient solutions are mixed and drip into the conical groove 3276 at the liquid preparation hole 3270.
