Abstract
Abstract An improved monitor for use in a catheterizing tube system has a hollow closed chamber, preferably resilient, containing test viewing means, for example, a transparent portion of the chamber, and urine testing means disposed within the chamber. The urine testing means includes a test medium which is visually responsive to a preselected urine factor to be tested. Urine transferring means, such as a needle, communicate between the chamber interior and the exterior. Catheter attaching means may be provided for releasably connecting the monitor to a urine catheter drainage system. The catheter attaching means may include a flexible shield extending forward from the front end of the chamber for releasably engaging the outer surface of one arm of the catheter Y tube. The device is constructed so as to protect the attaching element from damage and inhibit inadvertent contact therewith. The monitor is disposable and therefore permits replacement for repeated monitoring of urine as it passes through the catheter. Multiple compartments may be provided in the monitor chamber for simultaneous testing of the urine for one or a plurality of urine factors. In addition, the device may readily be used for sampling urine without in situ testing, if desired.
