Abstract: A ventilator system includes a first air tank, a plurality of second air tanks communicated with the first air tank, a plurality of breathing devices respectively communicated with the second air tanks, a plurality of first vacuum tanks respectively communicated with the breathing devices, and a second vacuum tank communicated with the first vacuum tanks. The first air tank has a positive pressure relative to the second air tanks. The second vacuum tank has a negative pressure relative to the first vacuum tanks.

Abstract: A fluoroscopy system includes a fluoroscopy device, an indicating assembly and a center control device. The fluoroscopy device includes a contoured support arm, an X-ray emitting unit, an X-ray sensor and a display unit. The contoured support arm has a first end part and a second end part opposite to the first end part. The X-ray emitting unit is located on the first end part and is configured to emit an X-ray. The X-ray sensor is located on the second end part to sense the X-ray. The display unit is electrically connected to the X-ray sensor. The indicating assembly is located near the contoured support arm and includes a plurality of light emitting units. Each of the plurality of light emitting units is rotatable and configured to emit a light plane. The center control device is electrically connected to the fluoroscopy device and the indicating assembly.
