Embedded adjustable nasopharyngeal flusher

Abstract

The invention discloses an embedded adjustable nasopharyngeal flusher. The embedded adjustable nasopharyngeal flusher comprises a handheld device, a positioning dial plate and a multi-directional / unidirectional flushing pipe. According to the embedded adjustable nasopharyngeal flusher, the flushing pipe is directly placed in the nasopharyngeal cavity through the nasal cavity, a flushing fluid directly flushes the nasopharynx, and since the flushing fluid flows from inside to outside, the flowing direction of the flushing fluid is consistent with the discharge direction of snot, thereby furtheraccording with the principle of physiological functional science of the human body; through personalized setting of use parameters, the water outflow direction and angle are controlled, thereby beingcapable of avoiding dizziness, secretory otitis media, even deafness and other complications which are caused by the fact that the flushing fluid flushes the middle ear through the auditory tube to the maximum extent. The embedded adjustable nasopharyngeal flusher comprises two types of flushing pipes, wherein the sector multi-directional flushing pipe can meet the needs of daily flushing, especially be suitable for patients with poor effects after the nasopharyngeal flusher is in use; the unidirectional flushing pipe can directionally flush an important part of the nasopharynx, especially besuitable for patients with nasopharyngeal ulcer.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an implantable adjustable nasopharyngeal irrigator. Background technique [0002] The nasopharyngeal cavity is located at the rear of the human nasal cavity and is relatively deep. Cancer of the nasopharyngeal cavity mucosa is called nasopharyngeal carcinoma. Nasopharyngeal carcinoma is a high-incidence tumor in my country, and radiotherapy is the first choice for treatment. Radiation therapy will cause lasting damage to the nasopharyngeal mucosa, which needs to be kept clean and rinsed regularly. [0003] At present, there is no dedicated nasopharyngeal cavity irrigator. Nasopharyngeal cancer patients generally use a nasal cavity irrigator instead. The irrigator is placed in the nasal vestibule, and the irrigator is squeezed to make the irrigant flush backward from the nasal vestibule. The flushing liquid in the above method is washed from the outside to the inside,...

AI Technical Summary

Problems solved by technology

The flushing liquid in the above method is washed from the outside to the inside, and the effect of cleaning the nasal cavity is good, but it is difficult for the flushing liquid to reach the nasopharyngeal cavity

In order to improve the cleaning effect, patients are generally required to inhale vigorously while rinsing in order to allow the irrigating fluid to reach the nasopharyngeal cavity. However, this method is difficult for patients to master, and it is easy to cause coughing and aspiration, which may lead to respiratory infections and increase the suffering of patients. , so the nasopharyngeal cleansing effect is not ideal

[0004] A small number of patients with nasopharyngeal carcinoma will develop nasopharyngeal radiation ulcers after radiotherapy. The ulcers are often deep and accompanied by bacterial infection, which is persistent and persistent. In clinical practice, it is necessary to focus on the ulcer site and wash it for a long time, but the current nasal irrigation method cannot be achieved
