Description

Technical Field

[0001] This utility model relates to the field of nasogastric tube technology, specifically a nasogastric tube injection heating device. Background Technology

[0002] Patients who have undergone esophageal surgery, are in a coma, or have difficulty swallowing cannot eat orally. In order to ensure the patient's nutritional supply, a nasogastric tube needs to be inserted. Liquid food is then injected into the tube at regular intervals using a syringe. During the process of injecting liquid food through the nasogastric tube, the food needs to be heated to avoid causing discomfort to the patient due to excessively low food temperature.

[0003] In existing technologies, conventional nasogastric tube injection heating devices mostly use electric heating films and electric heating rods to heat liquid food during use. However, because the electric heating films and electric heating rods are in fixed positions, there are temperature differences during heating, and the heating efficiency is low, making them very difficult to use. At the same time, the heating devices have only one function, which is heating, and cannot crush or filter larger particles in liquid food, which can easily cause blockage of the nasogastric tube and is not conducive to use.

The liquid food in the heating chamber 3 is stirred to make the heating more uniform, faster, and more efficient, which is convenient for use. The heating rod 702 drives the rotating shaft 603 to rotate in the bearing assembly 602 through the rectangular groove 12. The rotating shaft 603 drives the pulverizing blade 604 to rotate. The pulverizing blade 604 pulverizes larger particles on the upper side of the filter screen 601, effectively preventing the nasogastric tube from being blocked, making it safer and more reliable to use. The heated and pulverized liquid food flows into the nasogastric tube through the insertion tube 9. The temperature sensor 103 detects the liquid food in the heating chamber 3 and feeds the information back to the controller 101. The controller 101 displays the temperature information on the operation display screen 102.

[0034] In summary, this nasogastric tube injection heating device, while heating liquid food, also adds a stirring function, making the heating more uniform and faster. It can also filter and crush larger particles in the liquid food, effectively preventing the nasogastric tube from becoming blocked, making it safer and more reliable to use.
