A device for cleaning the external auditory canal

Abstract

The invention discloses an external auditory canal cleaning device. The problems that existing flushing cleaning and negative-pressure cleaning effects are not obvious, and the external auditory canalcannot be well cleaned are solved. The external auditory canal cleaning device comprises a liquid supply device, a liquid inlet pipe is connected to the upper end of the liquid supply device, a sealing bag is fixedly connected to the upper end of the liquid inlet pipe, multiple liquid inlets are formed in the side wall of the end, close to the sealing bag, of the liquid inlet pipe, and an air feeding pipe is arranged in the liquid inlet pipe, and communicated with the sealing bag; multiple layers of elastic fiber bundles are circumferentially and uniformly distributed on the side wall of theupper portion of the liquid inlet pipe, the upper ends of the elastic fiber bundles are fixed to the side wall of the liquid inlet pipe, and the lower ends of the elastic fiber bundles tilt outwards in the radial direction; the lower end of the air feeding pipe penetrates through the side wall of the liquid inlet pipe and is arranged at the outer side of the liquid inlet pipe and connected with anair injection device; a supporting device is arranged below the liquid supply device, and the liquid supply device is fixed to the supporting device.

Description

technical field [0001] The invention relates to the technical field of external auditory canal cleaning, in particular to an external auditory canal cleaning device. Background technique [0002] The external auditory canal is an "S" curved bend from the external ear door to the tympanic membrane, with a length of 2.5 to 3.5 cm. From the outside to the inside, the external auditory canal first moves forward, then turns backward, and finally forward and downward. The outer 1 / 3 of the external auditory canal is cartilage , which is continuous with the flexible tube of the auricle; the inner 2 / 3 is the bony part, which is an oval short tube surrounded by the squamous part of the temporal bone and the tympanic part. Since pulling the pinna can move the cartilage, when checking the external auditory canal and tympanic membrane, pull the pinna backwards and upwards to straighten the external auditory canal. The baby's external auditory canal is almost entirely supported by cartil...
