Fixed-quantity infusion device for nasogastric tube feeding

Abstract

Provided is a fixed-quantity infusion device for nasogastric tube feeding. The fixed-quantity infusion device comprises an injector and an infusion device body, wherein the injector is provided with a piston rod. The injector is placed in a fixed groove of the infusion device body, a fixed-quantity control device is arranged on a push rod of the infusion device body, and a fixed-quantity adjusting device composed of an L-shaped limiting hook and an L-shaped limiting rod or a fixed-quantity adjusting device composed of a wedge-shaped sliding block, a threaded rod and nuts is arranged on one face, facing towards a trigger, of a handle of the infusion device body. The simplified structure can be obtained by adding scales on the push rod and removing the fixed-quantity adjusting device. The fixed-quantity infusion device is simple in structure, convenient to use and especially suitable for nasogastric tube feeding at home or nasogastric tube feeding of self-made homogenate, and fixed-quantity infusion can be achieved; the fixed-quantity infusion device can play a filtration role, avoid pipe blockage, reduce link contamination and avoid the opportunity of increasing intestinal infection; the tail end of the infusion device is connected with an outer pipe through the handle, the phenomenon that a joint falls off in the process of operation can be avoided, and the fixed-quantity infusion device is clean, economical and convenient to use.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a quantitative infusion device for nasogastric tube feeding. 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 preparation. Since ...

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.
