|Part II - Using Treatment Room Equipment Operating the Patient Positioning System Manually (Emergency Release Mode) |
WARNING The Radiation Therapy Technologist (RTT) shall be trained and
exercised to perform efficiently and safely the emergency release mode
operations.
WARNING The emergency release mode shall be used only if the Patient
Positioning System (PPS) or the patient positioning devices do not
respond to control or are likely to be unsafe for operation.
The emergency release mode can be used in the following situations:
- complete power failure, loss of patient positioning device control.
- critical positioning devices failure, severe collision.
- serious patient condition requiring specific way of release (ex.: patient
stucked, incident,...).
Any other use of the emergency release mode is forbidden.
WARNING In emergency release mode:
- The PPS Robot requires a lot of force to be moved by hand, even with
the brakes released, ensure that you are assisted to move the robot
safely and efficiently.
When you lower the robot (by joint 3 release), the couch will tilt by
gravity. The patient must be held during this operation at all times to
avoid falling or severe injuries due to accessories.
- When releasing joint 3 brake: it is released by pulse that can induce
jerks. These jerks and bumps might cause injury.
WARNING If the emergency hand pendant/emergency release mode is used, the
references of the robotic patient positioner is lost. Call IBA personnel to
reset the system.
