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.
A urine measuring instrument for receiving, collecting and measuring urine from a catheterized patient comprising a transparent, graduated container with an upper inlet and a lower outlet to which a urine bag can be connected, said container being subdivided into several side-by-side vertical chambers into the first of which the inlet communicates, all the chambers being open to one another at the top and separated from one another at the bottom by a multi-path valve, all the chambers being in communication with the container outlet through said valve, and each chamber having a scale thereon.
A system for producing a display of the amount of glucose in a urine or serum sample including conventional sense and reference electrode adapted for placement in a urine or serum sample to produce a differential voltage signal which varies as a function of the amount of glucose in the sample, an amplifier to amplify this differential voltage, an analog to digital converter for providing a binary output, conventional binary coded decimal to seven segment decoder/driver circuits which provide outputs to incandescent displays which can provide seven segment outputs in any desired colors.
In a system for monitoring fluid for microbial contamination, successive samples of the fluid to be monitored are aseptically directed periodically to a growth medium. A detector detects gaseous metabolic products evolving from the growth medium to provide an indication of incipient contamination of the fluid being monitored.
