What are the working principle and technical requirements of electric operating table?
First, the working principle of the electric operating bed:
The electric operating bed is powered by electro-hydraulic, and the main control structure is composed of a control switch, a speed regulating valve and a solenoid valve. The hydraulic power source is provided by an electro-hydraulic gear pump to control the reciprocating motion of each two-way hydraulic cylinder, and the operation is controlled by the handle buttons. The bed can be changed in various positions, such as lifting, left and right, forward and backward, lower back lifting, moving and fixing, etc., so that it can meet the requirements of surgical operations.
Second, the technical requirements of the electric operating bed:
Most of the electric operating beds use hydraulic cylinders or air spring cylinders, and the base of the bed adopts a Y-shaped design to ensure that the operating bed has relatively high stability and relatively free space, so that medical staff can approach the surgical patients at zero distance. The operating table should have very good mobility, with four-wheel landing design, easy to move, and have a central mechanical brake device, and the casters are locked or released through the center of the foot lever. The bearings are all sealed and waterproof, easy to clean, and the water, blood and suture heads during the operation will never be entangled in the bearings. Head and foot tilt and left and right tilt just need to gently squeeze the head handle to obtain the clinically required position. The leg and back joints are equipped with gas spring cylinder support structures, which make various adjustments gentle, silent, and vibration-free, and at the same time effectively protect the joint structure and prevent patients from falling. According to the individual characteristics of Chinese people, my country’s medical device industry standard stipulates: the length of the operating table is 2m and the width is 0.48m, the front and rear inclination angles of the whole table are not less than 25°, the left and right inclination angles are not less than 20°, and the folding angle on the head board is not less than 30°, The lower fold angle is not less than 45°, the upper fold angle of the back panel is not less than 80°, the angle between the back panel and the seat panel is not more than 90°, the lower fold angle is not more than 160°, the lower fold angle of the waist panel is not less than 90°, and the waist bridge is not less than 90°. The elevation shall not be less than 0.12m. At the same time, the industry standard also requires: the operating table product should use the double-leg plate structure as much as possible, the double-leg plate surface can be rotated to the two outer sides in the same plane, and the angle between the inner sides of the two leg plate surfaces after rotation is not less than 180° The adjustment adopts the stepless change type.
To sum up, if you want to extend its service life, the better way is to master some working principles.
