Probe cover having a blackbody
View Patent ↗A probe cover for an infrared electronic thermometer including a generally tubular body having open first and second ends. The body is sized and shaped to receive a probe of the infrared electronic thermometer into the body through the first end. The probe cover further includes a film closing the second end of the body. The film has a metallic region defining a blackbody portion for rapidly equilibrating to a temperature corresponding to the temperature of an object for viewing by a sensor of the electronic thermometer to measure the temperature of the object.
1. A probe cover for an infrared electronic thermometer comprising:
a generally tubular body having open first and second ends, the body being sized and shaped to receive a probe of the infrared electronic thermometer into the body through the first end; and
a film closing the second end of the body, the film including a non-metallic region and a metallic region defining a blackbody portion for rapidly equilibrating to a temperature corresponding to the temperature of an object for viewing by a sensor of the electronic thermometer to measure the temperature of the object.
2. A probe cover as set forth in claim 1 wherein the blackbody portion is located in a central region of the film.
3. A probe cover as set forth in claim 2 wherein the blackbody portion is made of a different material than the tubular body.
4. A probe cover as set forth in claim 1 wherein the cover comprises at least two spacers on an interior of the tubular body for engaging and spacing the body from the probe.
5. A probe cover as set forth in claim 1 wherein when the probe is received in the probe cover, the film is spaced axially away from the probe so that the film does not engage the probe.
6. A probe cover for an infrared electronic thermometer comprising:
a generally tubular body having open first and second ends, the body being sized and shaped to receive a probe of the infrared electronic thermometer into the body through the first end; and
a film closing the second end of the body, the film including a non-metallic region and a metallic region defining a blackbody portion for rapidly equilibrating to a temperature corresponding to the temperature of an object for viewing by a sensor of the electronic thermometer to measure the temperature of the object, the blackbody portion being made of a different material than the tubular body.
