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.

Claim 1
Independent Claim 114 words
An improved urine specimen collection device for use with a urinary catheter drainage system, which device comprises, a receptacle, said receptacle including one portion comprising a a hollow closed chamber including means for aspirating; urine from said system and a wall means at one end providing a fluid tight seal and a hollow penetrating means extending through said wall, at least the outer end thereof being pointed, said receptacle having a second portion extending from said first portion beyond the outer end of said penetrating means and spaced therefrom, said portion defining a means for releasably and hermetically connecting the hollow penetrating means and the receptacle means to a selected portion of said system.
Claim 2
Dependent Claim 114 words
An improved urine specimen collection device for use with a urinary catheter drainage system, which device comprises, a receptacle, said receptacle including one portion comprising a a hollow closed chamber including means for aspirating; urine from said system and a wall means at one end providing a fluid tight seal and a hollow penetrating means extending through said wall, at least the outer end thereof being pointed, said receptacle having a second portion extending from said first portion beyond the outer end of said penetrating means and spaced therefrom, said portion defining a means for releasably and hermetically connecting the hollow penetrating means and the receptacle means to a selected portion of said system.
Claim 3
Dependent Claim 38 words
The device of claim 1 wherein said hollow penetrating means includes a hollow needle centrally disposed through and extending forward from the front end of said chamber and communicating between the exterior and hollow interior of said chamber.
Claim 4
Dependent Claim 14 words
The device of claim 1 further including urine testing material disposed within said chamber.
Claim 5
Dependent Claim 12 words
The device of claim 3 wherein the chamber includes test viewing means.
Claim 6
Dependent Claim 17 words
