Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical equipment, in particular to an enteral nutrient solution preparation device. Background Art
[0002] Enteral nutrition solution is also called enteral nutritional suspension (TPF). Since the 1970s, when people realized that intestinal mucosal cells need to be in direct contact with chyme to proliferate and repair normally, the application of enteral nutrition solution has become more extensive; its main ingredients are water, maltodextrin, whey protein hydrolysate, vegetable oil, vitamins, minerals and trace elements, etc., which are essential nutrients for the human body. For some patients with malnutrition during the perioperative period, a nutrient mixture with a ratio of protein, fat and carbohydrates of 15:30:55 is needed to provide them with nutrition.
[0003] Since enteral nutrition solution cannot be stored for a long time, the hospital will count the total amount required each time for configuration. Therefore, the total amount configured each time varies greatly. The proportion of the three main ingredients not only requires the calculation of the weight of each ingredient, but also requires configuration personnel to weigh it multiple times. It is easy to make mistakes and affect the therapeutic effect of the nutrition solution. Since nutrients are easily affected by oxygen in the air and deteriorate, the stirring speed and solution shear strength need to be adaptively adjusted for different amounts of powder to minimize the contact time between the nutrient solution and the air.

[0020] Specifically, the mixing mechanism 7 includes two limiting rods 71, a multi-section telescopic sleeve 72, two L-shaped rods 73, a plurality of fifth gears 74, a plurality of winding springs 75, a plurality of mixing shafts 76, a plurality of hollow disks 77, a plurality of rotating plates 78, a gear ring 79, a reciprocating limiting slide 710 and a plurality of fixed shafts 711.

The limit rod 71 is driven to rotate by the rotation of the stirring shaft 13, and because the limit rod 71 is located in the reciprocating limit slide groove 710 and slides, it is worth noting that the reciprocating limit slide groove 710 is based on the same principle as the reciprocating screw rod, which is not elaborated in detail in the prior art, so that the limit rod 71 drives the multi-section telescopic sleeve 72 to move reciprocatingly up and down, and the multi-section telescopic sleeve 72 drives the gear ring 79 to move synchronously when it moves up and contracts. When the gear ring 79 moves to mesh with the fifth gear 74, the fifth gear 74 is driven to revolve through the rotation of the stirring shaft 13. Since the gear ring 79 rotates with the multi-section telescopic sleeve 72 and is fixedly connected to the L-shaped rod 73, the fifth gear 74 rotates, the fifth gear 74 rotates and drives the mixing shaft 76 to rotate synchronously, the rotation of the mixing shaft 76 drives the winding spring 75 to wind, the synchronous mixing shaft 76 drives the rotating plate 78 to rotate synchronously, the rotating plate 78 rotates to perform secondary mixing and shearing on the inside of the multi-section telescopic sleeve 72, and when the gear ring 79 moves down and disengages, the rotating plate 78 and the mixing shaft 76 reverse under the action of the resetting of the winding spring 75; the solution stirred and mixed in a single direction is dispersed and stirred, and the resetting of the winding spring 75 drives the rotating plate 78 to reverse to further mix the solution evenly, and the mixing frequency is adaptively adjusted according to the total amount of the solution to ensure its mixing efficiency.

The stirring shaft 13 rotates to drive the hollow column 62 and the stirring blade 61 to stir the solution. The agglomerated and undissolved powder enters the hollow column 62 along the through groove 63 under the action of centrifugation. Then the multi-section telescopic sleeve 72 moves downward to drive the corresponding disc 65 and the wedge rod 67 to move downward. The wedge rod 67 abuts against the wedge block 610 to drive the disc 65 to rotate. The rotation of the disc 65 makes the offset groove 66 correspond. When the rotating plate 78 is reset, the interior of the multi-section telescopic sleeve 72 is in a sealed state, so that the internal air pressure is reduced when the multi-section telescopic sleeve 72 is extended, so that the agglomerated and undissolved powder is sucked into the multi-section telescopic sleeve 72 when the offset groove 66 corresponds. The powder agglomerated at the bottom is concentrated inside the hollow column 62 by the principle of centrifugal force while stirring and mixing, and the powder agglomerated at the bottom can be collected for subsequent centralized mixing and shearing, and the mixing effect is good.
[0022] Specifically, the two L-shaped rods 73 are both telescopic structures.
