Abstract:
The enuresis alarm described is a portable device designed for 'toilet training' of mentally sub-normal children. It weighs 70 gm with battery, has dimensions of 90 x 60 x 30 mm and conforms to DHSS recommendations. The battery life is over 1000 hours (6 weeks) in continuous use. Total component cost is is pounds 6.20 (in 1978), construction is simple and the circuit may be used as a conventional nocturnal enuresis alarm.

The Micturition Reflex
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Holter Monitor: 24-Hour Monitoring
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...
