Did the Delivery System Evolve from Ordinary Seats?

Ⅰ. The development of dental treatment table


We all know that the delivery system is one of the main medical equipment in dentistry, which is of great help to the work of dentists, facilitates operation and improves efficiency. So, how did the delivery system develop?


1. Ordinary seat


At first, there was no special delivery system, but ordinary seats were used, or ordinary seats were slightly modified as a delivery system. In 1790, a slightly modified delivery table appeared. There was a fixed headrest on it, the backrest could not be adjusted in angle, the right armrest could place instruments, the patient's position could not be changed with the treatment position, and the delivery table had foot controls, which could be pushed and moved. Rotate the direction to facilitate changing the seat position.


2. Manual adjustment of the delivery system


The hand-crank delivery system used in 1875 has a crank handle on the right to adjust the height of the delivery system; the left has a mouthwash system and a spittoon, and is equipped with an instrument tray, similar to the oil pump delivery system currently used; The backrest can be adjusted by the handle, and the patient's body position can be adjusted according to the treatment needs to be close to the horizontal position; the position of the headrest can also be adjusted, which can be locked with the handle; the footrest is wide and convenient. Illuminated delivery systems appeared in 1888.


3. Oil pump adjustment delivery system


In 1887, Ritter, a German, established a dental equipment production factory in New York, USA with his special expertise in the field of precision machinery. The novelty of its products is the oral treatment chair.


Equipped with two magnifying glasses, the different treatment positions of the patient can be adjusted through the oil pump. The dental treatment unit is equipped with a hydraulic device, which is called an oil pump dental treatment unit, which has quickly become popular and continues to this day. Its advantages are good performance, less failure, and longer service life, which can meet the general treatment of oral diseases.


Use the pedal lever to press the oil into the pump, push up the piston to raise the chair body, turn the chair lowering lever with your foot, open the oil drain hole of the pump, and press the piston by the weight of the dental treatment table and the patient's weight. The oil is released from the pump and the seat is lowered.


The pitch angle of the backrest of the dental treatment table can be adjusted by hand, the angle and length of the headrest can be adjusted, and the angle of the armrest can also be adjusted to suit patients of different shapes.


4. Electric adjustable delivery system


Modern delivery systems are powered delivery systems. At the beginning, the electric dental delivery table appeared in the early 19th century. The lift, tilt and headrest angle of the chair were adjusted electrically, and the patient's treatment position was changed from sitting to lying. Feel comfortable and relieve the patient's tension. At the same time, it is convenient for doctors to operate, overcomes the forced position, and reduces labor intensity.


The dental treatment table is developed from an ordinary seat. It has undergone various technological reforms along the way, from hand cranking, oil pump to electric adjustment, so as to form today's convenient dental treatment table. The power of technology cannot be underestimated. Impressive.
