Problems solved by technology

[0003] The purpose of the present invention is to provide a single-operated otoscope with adjustable focal length, so as to solve the problem in the prior art that the doctor needs to operate with both hands when performing an inflation test on the patient's ear canal, and the cooperation of others is required when adjusting the focal length. Realize the purpose of being able to complete the inflation inspection of the ear canal with one hand, complete the adjustment of the focus distance by one person, and improve the inspection efficiency

Embodiment 1

[0023] Such as Figure 1 to Figure 4 The single-person operation otoscope with adjustable focal length includes a base 1, an ear speculum fixed on the base 1, and a convex lens 2 whose axis is collinear with the axis of the ear speculum, and is characterized in that , also includes a handle, the top of the handle is fixedly connected to the mirror base 4, the mirror base 4 is fixedly connected to the base 1 through the connecting rod 5, and the top of the mirror base 4 is fixedly connected to the mounting column 6, The axis of the mounting column 6 is parallel to the axis of the ear speculum, and the end of the mounting column 6 near the direction where the ear speculum is located is provided with a light source 7, and the top of the mounting column 6 is provided with a linear slot 22. The long axis of the groove 22 is parallel to the axis of the mounting column 6, and the mounting plate 26 is arranged on the mounting column 6. Two threaded holes distributed along the long axi...

Embodiment 2

[0025] Such as Figure 1 to Figure 4 The single-person operation otoscope with adjustable focal length is shown. On the basis of Embodiment 1, the outer shell 3, the main shaft 8, and the annular piston 10 are all made of stainless steel. The outer shell of the annular piston 10 A rubber sealing ring 25 is embedded on the surface. The outer shell 16 is made of silicone material, and the inner shell 17 is braided by metal wire with an outer diameter of 1 mm. In this embodiment, after the doctor pushes the push block 12 upwards, he only needs to relax his fingers to reset the annular piston 10 under the reset force of the spring 24, so that the process of pumping air in the ear canal can be realized by relaxing the fingers. It is only necessary to exert force to push the push block 12 upwards, and then relax to realize a complete process of inflating and pumping air.

[0026] A more preferred embodiment is: a spherical buffer cavity 19 is provided inside the mirror base 4, and...

Abstract

The invention discloses a single-person-operated otoscope with adjustable focal length, which realizes the adjustment of the focal length by a single person. The adjustment process can be completed bya single person without the assistance of a nurse or other persons, and the observation of a convex lens by a doctor in the adjustment process can be ensured, so as to ensure the grasp of the accuracy of the adjustment of the focal length. After the doctor pushed the block upwards, the doctor can relax the fingers, the annular piston can be restored under the returning force of the spring, so that the finger can be relaxed to realize the aspiration process in the ear canal to complete a complete blowing and pumping process; the other hand is released to assist with the examination, to adjustthe position of the end of the speculum, manually guide and regulate the ear of the patient or write and record the disease in real time. The present invention solves the problems in the prior art that the speculum is taken out and adjusted or recorded after several times of inflating and then re-inserted into the speculum to inflate again, which leads to tedious operation and low efficiency,.

Description

technical field [0001] The invention relates to the field of ear inspection, in particular to a single-person operation otoscope with adjustable focal length. Background technique [0002] Otoscope is a commonly used instrument for examining the external auditory canal and tympanic membrane. It is shaped like a funnel and has different calibers. It is composed of a set and is selected according to the diameter of the external auditory canal of the patient. The principle is to use a magnifying glass to magnify the image of the ear canal inside the ear for easy examination by the doctor. The otoscopes in the prior art are gradually developing in the direction of electronization and image visualization. By integrating a camera on the otoscope, the internal image of the ear can be intuitively displayed directly on the display screen. However, compared with the traditional magnifying glass type otoscope, this kind of otoscope is expensive, the cost is significantly increased, an...
