摘要： Urine specimen containers combined with a temperature sensitive member which is capable of signalling a spurious urine specimen when placed in a sufficiently close heat exchange relationship with a urine specimen. The temperature sensitive member contains portions which change color irreversibly at preselected temperatures when placed in sufficiently close heat exchange relationship with a urine specimen. The temperatures at which the irreversible color changes are made are selected slightly below normal body temperature and slightly in excess of normal body temperature such as from about 90.degree. F. to about 100.degree. F. The urine specimen collector itself includes a bowl-shaped member with an integral handle. The bowl-shaped member is contoured to fit to close proximity to the body of the user. A cover member is pivotally attached to the handle and functions as a splash guard for the user. The cover member also has a raised boss terminating in an open top to permit urination through the cover member. The opening of the raised boss in the cover member is substantially in line with a threaded connection for a collection container which is screwed onto the bottom of the bowl-shaped member. The cover member has a portion thereof spaced from a frontal portion of the bowl-shaped member to provide an overflow from the bowl-shaped member.

摘要： A method of and apparatus for dispensing rubber gloves in an aseptic condition for insertion of the hands of a user. The gloves to be dispensed are contained within a chamber in a suitable housing provided with hand holes for a user. The gloves are attached to a continuous web of material provided with an aperture at each glove attachment for insertion of a hand of the user. Each glove is covered by a packaging film that is lightly perforated at each glove. The gloves are fed intermittently into registry with the hand holes in the housing. The user activates a vacuum pressure which is in fluid communication with the hand holes causing the gloves to expand and rupture through the film of packaging material. The user inserts his hands, deactivates the vacuum pressure, thrusts his hands further into the housing to detach a temporary retention of the gloves and removes his hands from the housing with the gloves aseptically applied.
