Problems solved by technology

At present, all the irrigators on the market are nasal irrigators. Due to the deep anatomical structure of the nasopharynx, the water flow is difficult to reach the nasopharynx, and the rinsing effect on the nasopharynx is poor. Therefore, it is necessary to develop a irrigator for the nasopharynx to meet the clinical needs of the majority of patients with nasopharyngeal carcinoma

Abstract

The invention provides a nasopharynx flusher which comprises a liquid storage bottle, a pressurizing device and a flushing hose with a flushing hole in the end. The flushing hose is a three-way tube and comprises a head part for liquid output, a middle part for liquid guiding and two tail parts for liquid feeding. An arc face is arranged at the top end of the head part, the flushing hole is formed in the top end of the head part of the flushing hose, and an airbag is arranged at the joint of the head part and the middle part. The middle part comprises a cleaning liquid channel and a pressurized fluid channel separated from the cleaning liquid channel. Hand touch scales protruding outwards are arranged on the outer surface of the middle part. The tail parts comprise the first tail part communicated with the flushing hole through the cleaning liquid channel and the second tail part communicated with the airbag through the pressurized fluid channel. The liquid storage bottle communicates with the first tail part through the pressurizing device, the pressurizing device is a liquid pump, and a check valve is arranged in the second tail part. The nasopharynx flusher is easy and convenient to use, can flush the nasal cavity and the nasopharynx, and can carry out hemostasis by compression to deal with the situation that the pharyngonasal cavity bleeds.

Description

technical field [0001] The invention relates to a nasopharyngeal irrigator for rinsing nasal cavity and nasopharynx, belonging to the technical field of medical devices. Background technique [0002] Nasopharyngeal carcinoma is a common malignant tumor of the head and neck in my country. Radiotherapy is the main treatment method. After radiotherapy, patients must perform nasopharyngeal irrigation for a long time to reduce local secretions and tumor recurrence. At present, all the irrigators on the market are nasal irrigators. Due to the deep anatomical structure of the nasopharynx, the water flow is difficult to reach the nasopharynx, and the rinsing effect on the nasopharynx is poor. Therefore, it is necessary to develop a irrigator for the nasopharynx to meet the clinical needs of the majority of patients with nasopharyngeal carcinoma. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a na...
