push type nasal irrigator

Abstract

The invention provides a push-pressing-type nasal irrigator which comprises a solution device for accommodating nasal washing liquid, a catheter assembly communicating with the solution device in a sealed mode and a spraying head. The spraying head communicates with the output end of the catheter assembly. The solution device comprises a flexible bag used for accommodating the nasal washing liquid, an outer barrel, an upper cover plate, a lower cover plate, a supporting plate, guiding rods and a pushing rod. One-time washing can be completed in the washing process of a patient nasal cavity, the nasal washing liquid in a container can be removed completely, the situation that air needs to enter a traditional structure and then washing can continue is avoided, the situation that the air enters the container, and consequently, the nasal washing liquid is polluted can be effectively avoided, thus the possibility of secondary infection of a nasal cavity of a patient is completely eliminated, the washing strength can be effectively ensured in the washing process, and the washing efficiency is improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a pushing type nasal washing device. Background technique [0002] Nasal washer is a kind of common auxiliary medical equipment. Existing nasal washer generally includes the following structure: bottle body, bottle cap, catheter and nozzle, one end of the catheter is sealed and communicated with the bottle cap and the other end of the catheter is communicated with the nozzle. The bottle body is a soft bottle made of flexible plastic. By squeezing the soft bottle, the nasal washing fluid flows out to rinse the patient's nasal cavity. However, the existing structure does not have continuity in the flushing process. When the bottle body is squeezed To a certain extent, the bottle body must be loosened, and then the external air enters the bottle through the nozzle and the catheter to be squeezed. This reciprocation will not effectively guarantee the continuity of the flushing, which will affect t...

The bottle body is a soft bottle made of flexible plastic. By squeezing the soft bottle, the nasal washing fluid flows out to rinse the patient's nasal cavity. However, the existing structure does not have continuity in the flushing process. When the bottle body is squeezed To a certain extent, the bottle body must be loosened, and then the external air enters the bottle through the nozzle and the catheter to be squeezed. This reciprocation will not effectively guarantee the continuity of the flushing, which will affect the flushing efficiency. More importantly, , when the external air enters the bottle, the solution in the bottle will be polluted due to bacteria and suspended particles mixed in the air, which will easily cause secondary infection of the patient, especially when there is a wound in the patient's nasal cavity. Potential health risks posed by patients are more serious
