A medical timing system has a programmed computer controlled display and audible buzzer, with inputs from a timing switch and a readout button which are connected together so that pregnancy labor pains may be timed, contraction patterns may be rehearsed by an expectant mother, and fetus movements may be counted. The medical timing system is preferably hand-held and compact so that the timing switch and readout button may be easily actuated and so that accurate and reliable timing measurements may be made and recorded through use of the system.

A labor contraction duration and interval timer comprising: a timing circuit that produces a timing signal; an electrical input device having a first state and a second state; a processor connected to said timing circuit and to said electrical input device, wherein: said processor samples said timing signal when said input device is changed from the first state to the second state at the beginning of a contraction, and again samples said timing signal when said input device is changed from the second to the first state at the end of a contraction, and said processor automatically determines the length of time between the most recent input device state changes after the input device is changed from the second state to the first state, which time is the length of the measured contraction; and said processor additionally automatically determines the length of time between the two most recent changes of the input device from the first state to the second state, after the input device is changed from the first state to the second state, which time is the length of time between the beginning of one measured contraction and the beginning of the next measured contraction, or contraction interval; and a device for reading out the determined contraction length and contraction interval data.
