Technical Field

[0001] The invention relates to the technical field of nursing care for patients with nasogastric feeding, and in particular to a nutrition pumping device for patients with nasogastric feeding. Background Art

[0002] Nasogastric feeding is a method of feeding the stomach by artificially inserting a gastric tube into the esophagus through the nasal cavity under special circumstances. The food is first ground into a paste using a grinder, and a large syringe is used to connect the large feeding port under the gastric tube connector. After the connection is secure, the push rod piston is manually pressurized to pump water and food into the patient's stomach to help patients who cannot swallow independently provide water and food, and maintain the body's metabolism, weight and nutrition.

[0003] At present, when using the existing nasogastric feeding patient nutrition pump device, the nutrient solution in the liquid storage cylinder is mainly pumped into the infusion tube through the material pump, and then the infusion tube enters the stomach through the patient's nasal cavity to complete the feeding. However, in actual use, the equipment is mostly placed on the patient's bedside table or on the ground. The infusion tube is easily pulled and pulled, causing the entire device to move or fall over, and the stability is poor, which greatly affects the use effect of the device. Summary of the Invention

By working the pumping pump 6, the nutrient solution in the liquid storage cylinder 3 can be pumped into the infusion tube 7, and then sent into the patient's nasal cavity for feeding.

[0036] The positioning mechanism includes a fixed frame 8 symmetrically arranged at both ends of the side wall of the bracket frame 1, a slide is provided in the fixed frame 8, and sliders 9 that can move toward or away from each other are symmetrically provided at both ends of the inner part of the slide. One end of the two sliders 9 extends to the outside of the bracket frame 1 and is provided with a positioning plate 10. A driving assembly is provided on the fixed frame 8, and the driving assembly is used to drive the slider 9 to move.

[0037] The driving assembly includes a bidirectional screw 11 rotatably connected to the bracket frame 1 through a bearing.

One end of the cavity 24 is rotatably connected to a threaded rod 30 through a bearing. The top of the threaded rod 30 extends to the outside of the support plate 23 and is provided with a fixed handle 31. One of the movable columns 25 is connected to the outside of the threaded rod 30 by a threaded engagement, and a support arm 32 is fixed to the bottom end of the other end of the movable column 25. The bottom end of the support arm 32 extends to the outside of the support plate 23 and is fixedly connected to the bottom end of the connecting column 33.

[0046] The outer ends of the two movable columns 25 are fixed with guide blocks 28, and both sides of the interior of the cavity 24 are provided with guide grooves 29 that match the guide blocks 28. Based on this, by providing the guide blocks 28 and the guide grooves 29, the stability of the movable column 25 when moving can be greatly enhanced.

By twisting the fixed handle 31, the fixed handle 31 can drive the threaded rod 30 to rotate, and then the threaded rod 30 can drive the movable column 25 to move, so that the movable column 25 drives the gear 27 to rotate through the tooth plate 26. Thereafter, the gear 27 can drive another movable column 25 to move through the tooth plate 26, so that the movable column 25 drives the connecting column 33 to move through the support arm 32, and then the connecting column 33 can drive the stopper 22 to rise and fall in the rotating cylinder 20.
