Abstract
Abstract A temperature measuring device for accurately measuring core body temperature is disclosed. The device utilizes freshly voided urine and the temperature thereof has been found to be an accurate measurement of said core body temperature. The device includes a receptacle having a well therein and a means for measuring temperature which preferably is a chemical thermometer. The well holds a sample of at least about 25 cc and includes a pedestal for mounting the temperature measurement device thereon so that in use the temperature measurement device will be submerged in the sample. Any conventional temperature measurement device may be used, including a chemical thermometer, an electronic thermometer, or the conventional mercury-in-glass thermometer. The device is intended to be stackable and disposable in the preferred embodiment.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
245 words
An apparatus for determining core body temperature by measuring the temperature of urine comprising: a receptacle for receiving said urine, said receptacle including an upper portion having an opening therein, a base portion which functions to receive said sample of urine, a circumferential lip portion surrounding said opening, said opening have a generally eliptical shape and adapted to receive urine from human females; a lid means for engaging said lip portion and forming an air and liquid-tight seal with respect to said lip portion; temperature measuring means for measuring the temperature of said urine as it is being collected and for providing an indication of said temperature for a prolonged period after collection thereby serving as an indication that said sample of urine was fresh when collected, said temperature measuring means comprising a removable chemical melting point type of thermometer; means for releasably attaching said temperature measuring means to said apparatus so that said temperature measuring means may be readily removed from said apparatus; supporting means comprising a pedestal-like means for supporting a first portion of said temperature measuring means a predetermined distance above the inside bottom of said base portion of said receptacle; pour spout means incorporated in said receptacle for removing urine from said receptacle; and, dead air space means located on the exterior of said base portion on the opposite side thereof from said pedestal-like means for insulating said urine from the temperature of exterior surfaces upon which said apparatus may rest.
Claim 2
Independent Claim
245 words
An apparatus for determining core body temperature by measuring the temperature of urine comprising: a receptacle for receiving said urine, said receptacle including an upper portion having an opening therein, a base portion which functions to receive said sample of urine, a circumferential lip portion surrounding said opening, said opening have a generally eliptical shape and adapted to receive urine from human females; a lid means for engaging said lip portion and forming an air and liquid-tight seal with respect to said lip portion; temperature measuring means for measuring the temperature of said urine as it is being collected and for providing an indication of said temperature for a prolonged period after collection thereby serving as an indication that said sample of urine was fresh when collected, said temperature measuring means comprising a removable chemical melting point type of thermometer; means for releasably attaching said temperature measuring means to said apparatus so that said temperature measuring means may be readily removed from said apparatus; supporting means comprising a pedestal-like means for supporting a first portion of said temperature measuring means a predetermined distance above the inside bottom of said base portion of said receptacle; pour spout means incorporated in said receptacle for removing urine from said receptacle; and, dead air space means located on the exterior of said base portion on the opposite side thereof from said pedestal-like means for insulating said urine from the temperature of exterior surfaces upon which said apparatus may rest.
Claim 3
Dependent Claim
32 words
The apparatus of claim 1 wherein said opening in said upper portion is larger in cross-sectional area than said base portion so that said apparatus may be stacked one inside the other.
Claim 4
Independent Claim
179 words
An apparatus for determining core body temperature by measuring the temperature of a sample of urine, said apparatus comprising: a receptacle having a well cavity therein for receiving said urine, said receptacle including an upper portion having an opening therein and a closed base portion; temperature-measuring means comprising a substantially flat temperature sensitive means; support means located in said well cavity for supporting a first portion of said temperature sensitive means and a second portion thereof extending along an inner wall of said receptacle, said support means comprising a pedestal-like means for supporting said temperature means a predetermined distance above said base portion, wherein urine collected in said receptacle substantially surrounds said temperature measuring means and contacts said temperature measuring means so that the temperature of said urine can be read directly from said temperature measuring means and further wherein said support means supports said temperature means at a distance far enough below the normal exposed surface of said urine as to minimize the effect of the cooling gradient of said sample of urine upon said temperature measuring means.
Claim 5
Independent Claim
179 words
An apparatus for determining core body temperature by measuring the temperature of a sample of urine, said apparatus comprising: a receptacle having a well cavity therein for receiving said urine, said receptacle including an upper portion having an opening therein and a closed base portion; temperature-measuring means comprising a substantially flat temperature sensitive means; support means located in said well cavity for supporting a first portion of said temperature sensitive means and a second portion thereof extending along an inner wall of said receptacle, said support means comprising a pedestal-like means for supporting said temperature means a predetermined distance above said base portion, wherein urine collected in said receptacle substantially surrounds said temperature measuring means and contacts said temperature measuring means so that the temperature of said urine can be read directly from said temperature measuring means and further wherein said support means supports said temperature means at a distance far enough below the normal exposed surface of said urine as to minimize the effect of the cooling gradient of said sample of urine upon said temperature measuring means.
Claim 6
Dependent Claim
