Abstract
The present invention relates to a fail safe method and apparatus for automatically securing an area during a medical radiation procedure. Upon initiation of the procedure, an electrical signal is sent from the medical device to the locking device, which automatically secures all passages to and from the radiation room. Upon completion of the procedure, a second signal automatically is sent from the medical device thereby opening the locking device and allowing free passage to and from the room.
Claims10
A method for securing all entry and exit passages to and from a radiation room during a medical radiation procedure comprising the steps of:
- providing a first electrical signal from a radiation device upon initiation of the medical procedure,
- transmitting said signal to a locking device for securing passage to and from said radiation area
- activating said locking device, and thereby securing said area.
An apparatus for securing all entry and exit passages to and from a radiation room during a medical radiation procedure comprising:
- an electrical signal contact (2) receiving an electrical signal from a medical radiation device (1),
- an electrically operated electromagnetic locking device (4) securing and locking all passageways (6) to and from said radiation room,
- a transmission line (3) receiving said signal from said signal contact (2) and transmitting said signal to said electrical electromagnetic locking device (4).
- said transmission line (3) including a relay device (7) having attached thereto a direct current transformer (8). and a control device (9) receiving an input voltage of 120 volts of alternating current and an outputs voltage of 12 volts direct current to said locking device.
