Abstract: A device for measuring the length and weight of an infant. The device includes a tray into which the infant is placed. The tray is located on a scale that is used to determine the infant's weight. A length measuring device is located adjacent the tray and includes a wand that extends into the tray and moves slidably along the length of the tray. An infant is placed within the tray so that the head of the infant is adjacent one end of the tray. The wand then slidably moves toward the infant until it contacts the sole of the infant's foot at which time a length measurement is taken. The length measuring device includes a breakaway switch and a rocker switch that stops the movement of the wand if it contacts the infant or another obstruction.

Abstract: An inexpensive disposable test kit for conveniently collecting airborne aerosol particulates on a bacteriological culture medium for determining the bacterial contamination of effluent air from respiratory equipment in hospitals and clinics. A collecting dish erves as a removable bottom on a cylindrical casing or main body. The latter has an integral guide funnel supported in its open upper end for directing the affluent stream downwardly against the culture medium in the dish. Apertures in an annular supporting web for the guide funnel, together with the convergence of the funnel with the casing wall help induce the flow of effluent in a pattern giving predictable or measured exposure of the culture medium to contact by the aerosol particulates. A removable sanitary cap for the funnel end of the casing serves subsequently as a protective cover for the culture medium dish when the latter is detached as a petri dish carrying the culture thus collected for incubation and examination.
