Abstract of Disclosure A propulsion-release safety vacuum release system (SVRS) for swimming pools monitors vacuum level in a suction pipe and reverses flow within the suction pipe if vacuum level exceeds a predetermined level. Thus, if a bather becomes entrapped on a suction outlet such as the pool main drain, the SVRS system not only releases the vacuum but also pushes away the suction-entrapped bather. In response to an elevated vacuum level, a vacuum-monitoring device actuates an automatic valve, which reverses fluid communications between the influent and effluent conduits of the pump and filter system. In this process, the suction pipe is converted from vacuum (negative pressure) to positive pressure. Thereafter, the automatic valve system automatically resets the SVRS to the original or normal flow configuration. The SVRS functions without interrupting operation of the swimming pool filtration system.

An urethral drain having deep external drainage channels, a low-profiled bladder retention segment, and a reversibly detachable collection segment, facilitates the draining of urine and fluids from the bladder. The low-profiled retention means minimizes bladder irritations and the deep external channels reduce the occurrence of infections. Incorporation of a reduced diameter smooth segment on the catheter, proximate the location of the external urethral sphincter allows the patient to void normally and at will. Modifying the size of this smooth segment aids the function of a defective sphincter in controlling urine leakage. The drain can be worn concealed within the urethra. Flushing action from normal voiding washes out particulate matters in the urethra and the concealed drain further minimizes contamination. Together, these features improve quality of life for patients needing catheterization.

A bathroom floor panel for use in an airtight and water tight space is configured to be efficiently dried in a few hours under ambient conditions. When water drops onto the floor panel, the surface tension of the water is broken by irregular-shaped portions and the water spreads without forming waterdrops. Also, the irregular-shaped portions reduce the flow velocity of the water due to a gradient of the panel, so as to prevent the water flowing in channels to a drain from being discontinued. With this, although the drain velocity of the water is low, substantially no water remains as isolated drops. Further, even if some water remain on the irregular-shaped portions after the water flows out the channels to the drain, any amount of water remaining in the channels is evaporated in a relatively short period of time because the amount of the remaining water is very small.
