Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a nasogastric medicine feeding device for the elderly which is convenient for quantitative dosage of medicines. Background Art

[0002] Nasogastric feeding is the process of 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 to maintain metabolism, weight and nutrition. When facing elderly patients who are unable to move, caregivers usually need to use syringes and gastric tubes to deliver liquid medicine to the patient through nasogastric feeding. Since the amount of medicine injected each time should not be too much, caregivers need to deliver a single portion of liquid medicine in multiple times. This requires caregivers to carefully observe the scale lines on the surface of the syringe every time they use a syringe to extract liquid medicine, so as to avoid extracting too much or too little liquid medicine with the syringe. This requires a high level of concentration from caregivers, and after repeated repeated attempts, caregivers are prone to mental fatigue. Utility Model Content
