Abstract

A thermometer device for temporal artery area measurement, configured to be used in a skin-touching stationary position, comprising an elongated body and a front portion having an end border arranged on a sensing plane (P), an array of N infrared sensors, with N greater than 8, a sensing region (SR) extending in the sensing plane over an area denoted SRA, at a distance denoted LF from a plane P2 containing the infrared sensors, the sensing region being encompassed within the border of the front end, an optical lens, interposed between the infrared sensors and the sensing region, to deviate light rays, wherein LF 2 <K×SRA, with K=3.

First claim

1 . A thermometer device for temporal artery area measurement, configured to be used in a skin-touching stationary position, comprising:
an elongated body and a front portion having an end border arranged on a sensing plane (P), an array of at least N infrared sensors, with N greater than 8, a sensing region (SR) extending in the sensing plane over an area denoted SRA, at a distance denoted LF from a plane P 2 containing the infrared sensors, the sensing region being encompassed within the border of the front end, at least an optical lens, interposed between the infrared sensors and the sensing region, to deviate light rays, wherein LF 2 <K×SRA, with K=3.

2 . The device of claim 1 , wherein the sensing plane extends over an area (SRA) which is at least 2 cm 2 , preferably at least 3 cm 2 , even more preferably at least 3.5 cm 2 .

3 . The device of claim 1 , wherein the sensing region (SR) has a substantially square shape.

4 . The device of claim 1 , further comprising an actuation switch and a display.

5 . The device of claim 1 , further comprising a wireless interface.

6 . The device of claim 1 , further comprising a removable protective cap.

7 . The device of claim 1 , wherein the body comprises one or more flattened portion.

8 . The device of claim 1 , wherein the length L 3 is less than 12 cm, and/or L 3 <4×D 3 .

9 . The device of claim 1 , wherein the front end has a cylindrical shape with an outer diameter D 3 which is greater than 30 mm and the sensing region (SR) is circumscribed in a diameter D 2 which is greater than 25 mm.

10 . The device according to claim 8 and to claim 9 , wherein L 3 <4×D 3 .

11 . The device of claim 9 , wherein 1>D 2 /D 3 >0.9.

12 . The device of claim 1 , wherein the body is circumscribed in a cylinder C defined by a primitive defined by the external edge of the front end border and the axis X.

13 . The device of claim 1 , characterized in that the device can be put in a stable manner in an upright stable standing position on the front end.

14 . The device of claim 1 , which comprises a PCB arrangement with a mother board and a daughter board arranged perpendicularly, the sensor array being soldered on the daughter board.

15 . The device of claim 1 , wherein the infrared sensors are thermopiles.
