Description

Technical Field

[0001] The invention relates to the technical field of nasopharyngeal washing, in particular to a nasopharyngeal washing device for radiotherapy. Background Art

[0002] The nasopharyngeal irrigation device is a tool used to clean the nasal cavity. A special nasal wash is sent into the nostrils. The cleaning liquid flows through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages, bypassing the nasopharynx, or is discharged from one nostril, or from the mouth. Through the above paths, with the help of the impact force of the saline water flow, the pathogenic bacteria and dirt that have accumulated in the nasal cavity are discharged, thereby restoring the nasal cavity to a normal physiological environment, restoring the nasal cavity's self-detoxification function, and achieving the purpose of protecting the nasal cavity. Radiotherapy can easily cause damage to the nasal mucosa, which needs to be treated with a nasopharyngeal irrigation device.

[0003] According to Chinese patent publication number CN118948611A, which relates to the field of medical device technology, a nasal irrigation device for radiotherapy nursing of nasopharyngeal carcinoma patients is disclosed, including a liquid placement bottle, one end of the liquid placement bottle is equipped with a connecting pipe, which is used to transfer the liquid in the bottle, one end of the connecting pipe is equipped with a nozzle for spraying the liquid in the liquid placement bottle, the outer side of the liquid placement bottle is also provided with a single-circulation mechanism that changes the air pressure in the bottle when pressed, and the inside of the liquid placement bottle is also provided with a pressure control mechanism, which is used to control the pressure on the bottle body, and the inside of the connecting pipe is also provided with a direction adjustment mechanism for adjusting the spray direction of the nozzle. The single-circulation mechanism includes an air bag, which is fixedly connected to one side of the outer wall of the liquid placement bottle, and the outer wall of the air bag is equidistantly connected to multiple inlet check valves. By controlling the air pressure in the liquid placement bottle, the situation that the hydraulic pressure is too large to impact the nasal cavity or the hydraulic pressure is too small to effectively rinse is avoided, thereby improving the comfort of nasal irrigation.

[0004] At present, the existing nasopharyngeal irrigation devices for radiotherapy and the above-mentioned cases are not convenient for flow control during use. When the built-in water pump is running, uneven water pumping will occur, which requires auxiliary adjustment to ensure the uniformity and stability of the water pumping.
