Paranasal sinus flusher used after nasal cavity operation

Abstract

The invention relates to the technical field of medical apparatus and instruments, and discloses a nasal sinus irrigator used after a nasal cavity operation, which comprises a bottle body, a liquid storage tank is placed in the bottle body, a pressing ring is arranged at the top end of the liquid storage tank, a heating seat is fixedly connected to the bottom end of the inner wall of the bottle body, and a heating wire is fixedly connected to the top end of the heating seat. The top end of the bottle body is in threaded connection with a top cover. According to the paranasal sinus irrigator used after the nasal cavity operation, through the arrangement of the inflation air bag, the filter plate, the elastic spring and the blocking bead, the paranasal sinus irrigating head is inserted into the nasal cavity, the inflation air bag is squeezed by a human hand, and air in the inflation air bag enters the liquid storage tank from the rubber hose along the air inlet groove, so that the pressure intensity in the liquid storage tank is increased; liquid medicine in the liquid storage tank enters the liquid suction pipe from the sieve plate, enters the connecting pipe along the liquid suction pipe and then is sprayed into the nasal cavity from the paranasal sinus flushing head along the fixing pipe to clean the nasal cavity, the liquid storage tank does not need to be squeezed by hands, and operation is easy and fast.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sinus flusher for nasal cavity surgery. Background technique [0002] At present, during the recovery period of patients undergoing nasal surgery, there will be more blood scabs in the nasal cavity and sinuses (including maxillary sinus, ethmoid sinus, frontal sinus, and sphenoid sinus), and sometimes there will be more purulent scabs due to local infection. Therefore, within one to three months after surgery, patients still need to perform regular nasal irrigation, and use normal saline or a mixed drug rinse to rinse the nasal cavity. [0003] The structure of the existing sinus irrigator is simple and fast. The existing cleaning device squeezes the sinus irrigator so that the liquid medicine in the airbag enters the nose for rinsing. In the process of squeezing, a greater force is required , especially when the liquid medicine in the bottle becomes less, at the same ...

[0003] The structure of the existing sinus irrigator is simple and fast. The existing cleaning device squeezes the sinus irrigator so that the liquid medicine in the airbag enters the nose for rinsing. In the process of squeezing, a greater force is required , especially when the liquid medicine in the bottle becomes less, at the same time, after the existing liquid medicine is added to the medicine, the water and the medicine are mixed unevenly, and the medicine in the liquid storage tank cannot be heated at the same time. When the temperature is low, washing the nasal cavity will cause adverse effects. Stimulate
