Abstract
Abstract A device for accurately measuring core body temperature by measuring urine temperature is disclosed. The device consists of a sampling chamber including an insulated liquid crystal temperature array which will instantaneously display the temperature of the urine sample therein. The device of this invention is useful as an accurate measurement of the fertility cycles in females, and for the detection of ovulation and pregnancy. The device is also useful in the detection of hypoglycemia, hypothermia and fever.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
A device for measuring core body temperature in humans comprising: a funnel shaped receptacle having a mouth and an exit port adapted to receive urine voided directly thereinto; a chamber integrally attached to said receptacle at the exit port thereof for receiving at least a portion of the urine voided thereinto; said chamber having a base and upstanding walls and a transparent window mounted in at least a portion of said upstanding walls; liquid crystal temperature measurement means mounted within said chamber and affixed to said window for registering the temperature of urine voided into said receptacle and said chamber and for displaying said temperature registration through said window for external view.
Claim 2
Independent Claim
112 words
A device for measuring core body temperature in humans comprising: a funnel shaped receptacle having a mouth and an exit port adapted to receive urine voided directly thereinto; a chamber integrally attached to said receptacle at the exit port thereof for receiving at least a portion of the urine voided thereinto; said chamber having a base and upstanding walls and a transparent window mounted in at least a portion of said upstanding walls; liquid crystal temperature measurement means mounted within said chamber and affixed to said window for registering the temperature of urine voided into said receptacle and said chamber and for displaying said temperature registration through said window for external view.
Claim 3
Dependent Claim
20 words
The device of claim 1, further comprising means carried by said receptacle for mounting said device on a toilet seat.
Claim 4
Dependent Claim
19 words
The device of claim 2, wherein the walls and base of said chamber are constructed of heat insulating material.
Claim 5
Dependent Claim
35 words
The device of claim 3, wherein said liquid crystal means has a range of temperature registration of from about 35° to about 37° C., and a display accurate to about 0.2° C. within said range.
Claim 6
Dependent Claim
41 words
The device of claim 1, wherein the walls of said chamber extend integrally from the periphery of the exit port of said receptacle and the window has a longitudinal axis contained in a plane parallel to a plane containing the base.
Claim 7
Dependent Claim
36 words
The device of claim 2, wherein said mounting means further comprises a flange carried by said receptacle and extending outwardly from the mouth thereof, a portion of said flange adapted to rest on a toilet seat.
Claim 8
Dependent Claim
30 words
The device of claim 1, wherein said receptacle further comprises overflow port means disposed adjacent the mouth thereof so that said device will not overflow when urine is voided thereinto.
