Description

Nasal feeding device

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a nasal feeding device.

Background

Nasal feeding diet through nasally indwelling gastric tubes is an important gastrointestinal nutrition approach widely applied to critically ill patients. Currently, single-cavity nasogastric tubes are commonly used clinically, and the nasal feeding methods mainly comprise two methods, wherein an operator directly pushes nasal feeding liquid into a gastric cavity through an injector; the second is to utilize a push pump capable of regulating and controlling the push speed and temperature, so that the heated nutrient solution can be pushed into the gastric cavity at a certain speed.

However, the devices used in both prior nasal feeding methods suffer from various disadvantages.

First, there are conventional methods of manual bolus injection by caregivers using a syringe:

1. the steps are complicated. 2. The incidence rate of nasal feeding intolerance is high, the manual injection can cause adverse reactions of gastrointestinal tracts of patients, and even worse, dangerous events such as aspiration choking, choking and the like caused by backflow of nutrient solution can occur. 3. The labor cost is high, and each meal of the patient needs to be nasal fed through the nasogastric tube, so that the workload of clinical nursing staff is increased.

Secondly, the use of the nasal feeding liquid pushing and injecting pump saves manpower to a certain extent, realizes self-heating and speed control of the nutrient solution, but still has the defects: 1. the nasal feeding liquid injection pump needs to be matched with a special infusion tube and a nasal feeding liquid packaging bag. When liquids such as nasal feeding oral medicines, drinking water between meals, self-contained ginseng soup/juice of family members and the like are needed, a manual pushing injection mode is still needed by means of a syringe. 2. Manual washpipe cleaning is still needed after nasal feeding of the nutrient solution.

In addition, both nasal feeding devices exist: the pressure in the gastric cavity cannot be dynamically monitored in real time, the function of early warning the reflux risk is not provided, and the reflux of gastric contents can occur due to improper operation, so that the aspiration choking cough, aspiration pneumonia and even choking are caused. For patients who have gastric retention, when gastrointestinal decompression is needed, both nasal feeding devices need to be externally connected with a gastrointestinal decompression bag.
