[0001] The utility model relates to the technical field of medical equipment, in particular to a postoperative feeder. Background Art

[0002] After the operation, the doctor recommends that the patient consume liquid food due to the condition of the disease, which can help gastrointestinal digestion and reduce the burden on the stomach and intestines. Currently, a feeder similar to a syringe is generally used when feeding patients.

[0003] The existing postoperative feeder has a relatively simple structure and is shaped like a syringe. When in use, its capacity is small and the amount of liquid food sucked each time is small, which affects the normal feeding efficiency. Based on the existing technical deficiencies, the utility model designs a postoperative feeder. Utility Model Content

[0012] As a preferred technical solution of the utility model, a turning handle is installed on the top of the threaded rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The postoperative feeder has a material injection structure. After the volume tank is filled with liquid food, it is connected with the threaded tube by snapping. The volume tank is inverted so that the threaded tube is aligned with the threaded groove tube and rotated to connect the two. When the threaded tube is rotated into the threaded groove tube, the first push rod pushes the second push rod and squeezes the movable plug. At this time, the two springs are compressed by pressure, so that the second push rod drives the movable plug to move upward in the threaded tube, thereby exposing the through hole in the volume tank. At this time, the liquid food in the volume tank can flow into the extraction cylinder through the through hole, thereby increasing the amount of liquid food stored in the device each time, and achieving the purpose of large flow rate of the device;

[0015] 2. This postoperative feeder has a telescopic structure. When feeding a patient, the handle is turned to drive the threaded rod to rotate out of the fixed seat. At this time, the second sleeve is not fixed to the first sleeve. The two sliding blocks can slide in the sliding groove by pulling the second sleeve, thereby adjusting the length of the food-grade silicone head to be extended, which can be adjusted according to the conditions of different patients.
