A nasal lavage device with an openable and closable spray head

Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a nasal irrigation device provided with an opening / closing nozzle. The tail end of the external side of a drainage cover of a nozzle of the nasal irrigation device is provided with an annular external end sealing ring which is matched with an accommodating slot; an opening and closing seal ring is arranged on the outer side of the drainage cover in an inclined way; when the nasal irrigation device is used, the drainage cover rotates in the annular-shaped accommodating slot until a drainage hole is communicated with a drainage gap, so that a channel from a liquid medicine lead pipe to the drainage hole, to the drainage gap and to a drainage port is formed; liquid medicine is led to the drainage port by the high speed flowing at an spraying opening to form liquid medicine mist spray, thereby performing health care or treatment for users; when the medicine administration is needed to be stopped, the drainage cover rotates in the annular-shaped accommodating slot, the drainage cover rotates to the low position of the opening and closing sealing ring from the position of the drainage hole, and the drainage hole is located in a closed space formed by the opening and closing sealing ring and the external end sealing ring, so that the medicine administration is stopped fast, and liquid medicine is prevented from flowing out from the nozzle due to shut down, thus, waste is reduced; and moreover, the liquid medicine contamination caused by reflowing of the liquid medicine which is in contact with the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nasal lavage device provided with an openable and closable nozzle. Background technique [0002] A nasal irrigator is a tool used to clean the nasal passages. It usually uses a certain amount of compressed air to send normal saline or other medicines into the nostrils through the nozzle, flow through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages around the nasopharynx, or discharge from one nostril, or Discharge from the mouth. Through the above path, with the help of physiological saline or other bactericidal treatment and the impact of water flow, the accumulated pathogens and pollutants in the nasal cavity will be discharged, so that the nasal cavity can restore the normal physiological environment, restore the nasal cavity's self-detoxification function, and achieve For the purpose of protecting and treating the nasal cavity....

AI Technical Summary

Problems solved by technology

[0003] At present, the nozzle of the nasal irrigator includes a nozzle inner core provided with a compressed air channel, an air nozzle is arranged at the top of the nozzle inner core, a drainage cover is arranged on the upper cover of the nozzle inner core, and a drug drainage channel is arranged on the drainage cover, and the drainage channel leads the liquid medicine to the air nozzle. , through the high-speed flow of compressed air at the jet port, the liquid medicine is brought into the jet port through the drainage channel, and the medicine mist is formed for sterilization treatment; in this case, the start and stop of the medicine liquid are controlled by the air compression device, and the operation Inconvenient, can not quickly control the start and stop of the liquid medicine, in addition, when the air compression device stops, part of the liquid medicine will flow out from the nozzle, resulting in waste of liquid medicine, and some liquid medicine that may have been in contact with the outside world will flow back to the liquid medicine storage device , resulting in a certain degree of contamination of the liquid
