Abstract
Abstract Disclosed is a combination thermometer and fecal specimen sampling device which permits the concurrent sampling of a fecal specimen and measuring of body temperature from a single penetration of the rectum. The sheath comprises an elongated, rigid, cylindrical sheath with a partially cutaway distal end to form a scoop. The thermometer is inserted into an annular bore in the sheath.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
98 words
A device for simultaneously sampling a fecal specimen and measuring rectal temperature, comprising: (a) a rigid and elongated disposable tubular sheath having open proximal and distal ends, said distal end having rounded edges adapted for rectal insertion and at least partially cut away longitudinally and transversely to form a longitudinally open-ended scoop for collecting and containing a fecal specimen from the rectum; (b) an interior bore formed throughout said sheath; and (c) a thermometer removably inserted in said bore with a temperature sensing end thermally exposed adjacent said scoop for concurrently measuring rectal temperature and collecting said specimen.
Claim 2
Independent Claim
98 words
A device for simultaneously sampling a fecal specimen and measuring rectal temperature, comprising: (a) a rigid and elongated disposable tubular sheath having open proximal and distal ends, said distal end having rounded edges adapted for rectal insertion and at least partially cut away longitudinally and transversely to form a longitudinally open-ended scoop for collecting and containing a fecal specimen from the rectum; (b) an interior bore formed throughout said sheath; and (c) a thermometer removably inserted in said bore with a temperature sensing end thermally exposed adjacent said scoop for concurrently measuring rectal temperature and collecting said specimen.
Claim 3
Dependent Claim
29 words
The device of claim 1, wherein a diameter of said bore has similar dimensions to a diameter of said thermometer to inhibit sliding of said thermometer in said bore.
Claim 4
Dependent Claim
81 words
The device of claim 1, further comprising: (a) a cap attached to said distal end of said sheath to enclose said scoop and contain a fecal specimen therein; (b) a plunger for insertion into said sheath, said plunger having proximal and distal ends; (c) a blanket contained in said distal end of said plunger for contacting said specimen in said distal end of said sheath; (d) a friable fluid-carrying ampoule contained within said blanket for releasing a fluid on said blanket.
Claim 5
Dependent Claim
15 words
The device of claim 3, said fluid comprising a solution of hydrogen peroxide and ethanol.
Claim 6
Dependent Claim
23 words
The device of claim 3, wherein said distal end of said plunger is substantially concave for receiving said blanket and said fluid-carrying ampoule.
Claim 7
Dependent Claim
16 words
The device of claim 1, wherein said sheath is made of plastic, metallic or glass material.
Claim 8
Dependent Claim
38 words
The device of claim 1, wherein said sheath further comprises a radially inwardly extending shoulder at said proximal end, said shoulder engageable with a groove on said thermometer to inhibit longitudinal sliding of said thermometer in said bore.
Claim 9
Dependent Claim
17 words
The device of claim 1, wherein said interior bore is out of round for engaging said thermometer.
Claim 10
Dependent Claim
22 words
The device of claim 1, wherein said sheath includes a plurality of radially distributed longitudinal fins projecting inwardly into said interior bore.
Claim 11
Dependent Claim
19 words
The device of claim 1, wherein said scoop is formed from a circular cross-sectional arc of greater than 180°.
Claim 12
Independent Claim
135 words
A method for sampling a fecal specimen and measuring rectal temperature, comprising the steps of: (a) inserting into the rectum a device comprising: (i) a rigid and elongated disposable tubular sheath having open proximal and distal ends, said distal end having rounded edges adapted for rectal insertion and at least partially cut away longitudinally and transversely to form a longitudinally open-ended scoop for collecting and containing a fecal specimen from the rectum; (ii) an interior bore formed throughout said sheath; and (iii) a thermometer removably inserted in said bore with a temperature sensing end thermally exposed adjacent said scoop for concurrently measuring rectal temperature and collecting said specimen; (b) sampling said fecal specimen with said scoop in the rectum; (c) measuring said temperature with said rectally inserted thermometer; (d) withdrawing said device from the rectum.
Claim 13
Independent Claim
135 words
A method for sampling a fecal specimen and measuring rectal temperature, comprising the steps of: (a) inserting into the rectum a device comprising: (i) a rigid and elongated disposable tubular sheath having open proximal and distal ends, said distal end having rounded edges adapted for rectal insertion and at least partially cut away longitudinally and transversely to form a longitudinally open-ended scoop for collecting and containing a fecal specimen from the rectum; (ii) an interior bore formed throughout said sheath; and (iii) a thermometer removably inserted in said bore with a temperature sensing end thermally exposed adjacent said scoop for concurrently measuring rectal temperature and collecting said specimen; (b) sampling said fecal specimen with said scoop in the rectum; (c) measuring said temperature with said rectally inserted thermometer; (d) withdrawing said device from the rectum.
Claim 14
Dependent Claim
71 words
The method of claim 11, further comprising the steps of: (e) removing said thermometer from said sheath; (f) enclosing the distal end of said sheath containing the fecal specimen with a cap; (g) inserting a plunger into the bore in said sheath adjacent said fecal specimen, said plunger having a blanket wetted by an analyzing test fluid; (h) wetting said fecal specimen with said fluid; and (i) reading said test results.
