This invention discloses a liquid food feeding device, belonging to the field of medical clinical medical device technology. It includes a pressurizing component, a sealing cup component, and a silicone connector. A rubber hose is connected to one side of the pressurizing component, and the other end of the rubber hose is connected to the sealing cup component. A silicone connector is also connected to the side of the sealing cup component. This invention solves the problems of traditional devices that use a push rod to force liquid food into the patient's esophagus via a piston. Firstly, the flow rate cannot be well controlled during liquid feeding; excessive speed can lead to bloating or other discomfort. Secondly, pushing in viscous liquid food is difficult. This invention uses a rubber balloon as the power device, replacing the original push rod, and adjusts the air pressure as a buffer, achieving a better and more stable flow rate. A sealing cup is used to hold the liquid food, replacing the original tube. The use of a rubber balloon for pressurization achieves a labor-saving effect.

This utility model discloses an auxiliary traction device for gastroscopy, relating to the field of medical auxiliary instruments. It includes an anterior oral plate, one end of which is fixedly connected to a connecting strap, and the other end of which has an adhesive structure for fixing the end of the connecting strap. A tube-penetrating hole is formed through the middle of the anterior oral plate, and a U-shaped groove is formed on the lower side of the tube-penetrating hole. A supporting structure drives the outer side of a tongue depressor to rotate upwards, and under the action of leverage, the other end of the tongue depressor presses down on the tongue surface. The endoscope tube is then inserted into the esophagus through the tube-penetrating hole. After the lens of the endoscope tube is moved to the lesion site, a U-shaped sleeve is pressed down. During the downward rotation of the U-shaped sleeve, two linkage arms are squeezed closer together. At this time, two arc-shaped clamps hold the endoscope tube on both sides. During insertion, the clamping and fixing prevents the arms from being held up for a long time, facilitating subsequent stable operation by medical personnel and improving practicality.
