Fine-adjustable Nasogastric Tube Feeding Quantitative Infusion Device

Abstract

The invention relates to a finely-adjustable nasogastric-feeding quantitative infusion device which comprises an injector with a piston rod and an infusion device. The injector is placed in a fixing groove of the infusion device, and a quantitative control device is arranged on a push rod of the infusion device. A quantitative adjustment device is arranged on one surface, facing towards a trigger, of a handle of the infusion device. The quantitative adjustment device comprises a wedge-shaped slider and a nut, the wedge-shaped slider is arranged on one surface, facing the trigger, of the handle, and the nut is arranged at the bottom of the handle and provided with a threaded rod in a penetrating manner, one end of the threaded rod is connected to the bottom of the wedge-shaped slider, and the threaded rod is rotated to enable the wedge-shaped slider to slide on the surface, facing the trigger, of the handle. The finely-adjustable nasogastric-feeding quantitative infusion device is simple in structure, convenient to use, capable of realizing finely-adjustable quantitative infusion and particularly suitable for home or homemade homogenate intestine and stomach tube feeding, filtration effect can be achieved, tube plugging is prevented, link pollution can be reduced, and opportunity of intestinal infections is prevented from increasing; the tail end is connected with an outer tube in a handle manner, so that a port is prevented from disconnection during operation, and the finely-adjustable nasogastric-feeding quantitative infusion device is clean, economical and convenient.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a fine-adjustable nasogastric tube feeding quantitative infusion device. Background technique [0002] Nasogastric tube feeding has been widely used clinically, and can be slowly instilled through a nasal feeding pump or a nasogastric tube. Nasal feeding pump can be selected in the hospital, but for patients who are fed by gastrointestinal tube at home, it is specially purchased, and the cost is too high; while enteral nutrition pump tube dripping is acceptable for finished nutritional preparations in bottles or bags, but for self-made nutritional preparations. Liquid food or nutritional preparations that need to be dissolved in powder, due to uneven mixing or large particles, are likely to block the enteral nutrition pump tube, and need to use a syringe to inject into the gastrointestinal tube. [0003] The syringe currently used clinically is a syringe for intravenous drug prepara...

Problems solved by technology

Nasal feeding pump can be selected in the hospital, but for patients who are fed by gastrointestinal tube at home, it is specially purchased, and the cost is too high; while enteral nutrition pump tube dripping is acceptable for finished nutritional preparations in bottles or bags, but for self-made nutritional preparations. For liquid food or nutritional preparations that need to be dissolved in powder, due to uneven mixing or large particles, it is easy to block the enteral nutrition pump tube, and a syringe should be used to inject the gastrointestinal tube

[0003] The syringe currently used clinically is a syringe for intravenous drug preparation. Since this syringe does not have a filter device, medical staff or family members will filter the self-made homogenate with gauze or a fine colander, which leads to complicated operations and cumbersome procedures. It increases the chance of contamination and easily causes gastrointestinal infection; the needle plug is push-pull, and it will be very laborious for the injection volume of more than 100 ml.
