Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of maternal and child auxiliary device, more particularly to a gravity feeding auxiliary device for infants. BACKGROUND

[0002] ‌Gravity feeding is a kind of feeding method that uses the principle of gravity to flow milk into the stomach of premature infants through a gastric tube.‌This method makes milk evenly and slowly enter the stomach through gravity, avoiding the problems of reflux and gastric retention caused by too fast injection speed in traditional nasal feeding, thereby promoting the increase of milk volume and weight gain of premature infants, shortening the hospitalization time and reducing complications. Gravity feeding is suitable for premature infants with gestational age less than 34 weeks, children who are in coma and cannot eat, and children who are not suitable for eating, as well as newborns with unexplained vomiting.

[0003] At present, there are few gravity feeding auxiliary devices on the market. Clinically, a syringe barrel with the needle and plunger removed is usually used to connect a gastric tube, and after hanging, milk is poured into the syringe barrel for direct gravity feeding. Since the syringe barrel is of an open structure, the milk is easily contaminated by dust and bacteria in the air during gravity feeding, making it difficult to ensure the hygiene and safety during feeding. The separate syringe barrel structure is simple and light, and after hanging, it is not stable enough and is easily knocked over or tilted.

[0004] There are also gravity feeding auxiliary devices that use an external sleeve and a feeding bottle. The feeding bottle is loaded from above the external sleeve for use, thereby increasing stability. Since the gastric tube needs to be inserted into the stomach of the infant in advance, and is replaced every few days or even a week. During use, the feeding bottle can only be loaded from above the external sleeve, and the interface of the gastric tube inserted into the stomach of the infant in advance is connected to the bottom of the feeding bottle from below the external sleeve. Since the connection part is located inside the external sleeve, and the gastric tube interface is small, it is very inconvenient to connect and fix the feeding bottle and the gastric tube. In addition, since the infant needs to be fed about 8 times a day at intervals of 2-3 hours, the existing feeding bottle cannot be used for one-time use and needs to be repeatedly cleaned, increasing the workload of medical staff. And the infant who needs gravity feeding has poor resistance, and the requirement for sterility is high. Even if it is repeatedly cleaned, compared with the disposable syringe barrel, it is difficult to ensure the sterile state after long-term use of the feeding bottle. UTILITY MODEL CONTENTS
