I. Working principle of electric operating bed:
Electric operation bed by hydraulic power, by the control switch, speed regulating valve and solenoid valve control structure of the main body, through the electric hydraulic gear pump with hydraulic power source, control the bidirectional hydraulic cylinder reciprocating motion, and through the handle button control operation bed for a variety of position transformation, such as lift and tilt around, pour before and after, the small of the back lifting fixed, mobile, and other functions, Make it meet the requirements of surgical operation.
2. Technical requirements of electric operating bed:
Most of the electric operating bed adopts hydraulic cylinder or air spring cylinder, and the base of the bed adopts Y-shaped design to ensure that the operating bed has relatively high stability and relatively free space, so that the medical staff can get close to the surgical patients with zero distance. The operating bed should be very mobile, with a four-wheel landing design, easy to move, and a central mechanical brake, with casters centrally locked or released by foot bars. The bearings are all sealed and waterproof, easy to clean, and the water, blood and stitches in the operation will never be wrapped in the bearings. Head and foot tilt and left and right tilt only need to gently pinch the head handle to obtain the clinically required position. The leg plate and the backplane joint are equipped with a gas spring cylinder support structure, so that all kinds of adjustment is gentle, quiet, no vibration, and effectively protect the joint structure to prevent the patient from tipping over. According to the individual characteristics of Chinese people, China's medical device industry standard stipulates: The length of the operating table surface is 2m, the width is 0.48m, the front and back angles of the whole table are not less than 25°, the left and right angles are not less than 20°, the upper bending Angle of the head plate is not less than 30°, the lower bending Angle is not less than 45°, the backplane is not less than 80°, the upper bending Angle of the backplane and the seat plate is not more than 90°, the lower bending Angle is not more than 160°, the lower bending Angle of the waist plate is not less than 90°. The lumbar bridge elevation is not less than 0.12m. At the same time, the industry standard also requires that the operating table products should try to use the structure of the double leg board, the double leg board can rotate to the two sides in the same plane, and the Angle between the inner side of the two legs board after rotation is not less than 180° table, and all adjustments are stepless.
To sum up, if you want to extend its service life, the better way is to master some working principles.
