Technical Field

[0001] The utility model relates to the field of medical care equipment, in particular to a liquid food feeding device. Background Art

[0002] In the field of critical care, liquid feeding is one of the important means of nutritional support for patients. For patients who cannot eat independently or require special diets, liquid feeding equipment has become an indispensable auxiliary tool. However, traditional liquid feeding equipment has many deficiencies in functionality and convenience, and it is difficult to meet the needs of modern critical care. Traditional liquid feeding equipment often only has a single liquid food delivery function and cannot evenly stir the liquid food, which causes the liquid food to easily precipitate and agglomerate during storage and transportation, affecting the patient's digestion and absorption, especially when feeding liquid food with higher viscosity. This problem is more prominent. Traditional liquid feeding equipment lacks flexibility in feeding methods. They usually only provide a fixed feeding mode and cannot be adjusted according to the patient's specific situation and needs. This limits the scope of application of the equipment and cannot meet the personalized needs of different patients.

[0003] Therefore, it is necessary to provide a new liquid food feeding device to solve the above-mentioned technical problems. Utility Model Content

[0051] The device body is composed of a syringe 1 and a push rod 5. The syringe 1 is used to store liquid food. An injection head 2 is provided at one end thereof for delivering the liquid food to the patient's mouth. A piston head 3 is slidably connected to the inside of the syringe 1. The piston head 3 is pushed by the up and down movement of the push rod 5, thereby controlling the delivery of the liquid food.

[0052] In order to achieve uniform stirring of liquid food, the device is built with a rotary rod 6 and a stirring rod 8. The rotary rod 6 is located at the center of the syringe 1. The push rod 5 is slidably connected to the outside of the rotary rod 6. A spiral groove 7 is provided inside the rotary rod 6, which cooperates with the spiral strip 10 at the bottom end of the inner rod 9 inside the push rod 5. When the push rod 5 moves up and down, the inner rod 9 and its spiral strip 10 slide in the spiral groove 7, thereby driving the rotary rod 6 to rotate. The rotation of the rotary rod 6 further drives the stirring rod 8 to rotate. The stirring rod 8 is equidistantly fixed on the outside of the bottom end of the rotary rod 6 and is arranged in an inclined shape. Its bottom end contacts the inner wall of the bottom of the syringe 1 to form an effective stirring area. The bottom end of the stirring rod 8 is designed in a curved surface, which can better fit the bottom of the syringe 1 and improve the stirring effect.

[0053] When stirring is not required, the rotary rod 6 can be taken out and the bottom end of the push rod 5 can be sealed with a soft plug. After the bottom end of the push rod 5 is sealed with the soft plug, the pressing piece 11 on the top of the push rod 5 is directly pressed, and the piston head 3 slides in the syringe 1 to push the liquid food into the patient's mouth.
