Abstract:
1. A system for providing intermittent, two-way communication by a user in a sterile field, without threatening the sterile field, comprising: a first two-way communication device coupled with a sensor, the sensor and the first two-way communication device being configured to be mounted on the user so as to be portable with the user and located within the sterile field, a second two-way communication device being located outside the sterile field, said second two-way communication device being coupled to said first two way communication device; said sensor being configured to detect the presence of an object located closer than a predetermined distance from said sensor in a predetermined direction relative to said sensor; wherein when said sensor detects an object closer than said predetermined distance in said predetermined direction, said sensor activates a switch, said switch being configured to switch said first two-way communication device from receiving mode to transmitting mode; said system further comprising a retrigerable timer coupled to said switch and configured to switch said two-way communication device back to receiving mode automatically after an adjustable, pre-determined elapsed time; wherein said two-way communication device remains in transmitting mode until a predetermined amount of time has elapsed since said object has ceased to be located within said predetermined distance in said predetermined direction of said sensor.
