Otolaryngological examination chair for medical instrument

Abstract

The invention relates to the technical field of medical instruments, and discloses an otolaryngological examination chair for a medical instrument. The otolaryngological examination chair comprises abase plate, wherein rotating sliders are fixedly mounted at the top of the base plate, and a first pedal is stepped down, so that the first pedal compresses a first return spring through a pressing rod, when the pressing rod moves downwards, air in a fixing box can also be extruded, the air in the fixing box can be prepared to enter a supporting column through a non-porous connecting pipe, and through an air outlet pipe of the connecting pipe in the supporting column, the air in the air outlet pipe can push a baffle to the left side; and when the baffle moves, a second reset spring is extruded, so that the air in the connecting pipe can appear in an inner cavity of the supporting column through a ventilation pipe, a second telescopic column in the supporting column is driven to move upwards, and when the second telescopic column moves upwards, a seat plate is driven to move upwards, and the purpose of adjusting the height of the examination chair is achieved.

Problems solved by technology

[0003] After retrieval, Chinese Patent No. CN111956443A discloses an otolaryngology examination chair for medical equipment, including a base plate, support columns are provided on the front and rear sides of the upper surface of the base plate, and a second fixing plate is provided on the top of the support column. The front and rear sides of the fixed plate are slidably connected to the second guide rod. When the device is in the process of switching between sitting and lying positions, the pedals and the backrest can be rotated at the same time, so that the device can continuously support the patient's body. During the switching process, the left and right positions of the seat board can be moved freely to adapt to patients of different shapes. Although this adjustment method allows the patient to lie down for treatment, this method of lying down does not take into account the height of the doctor. This is very tiring for doctors
