Problems solved by technology

[0005] However, in the case of an ear-type thermometer, there is a problem that if the probe is not reliably inserted into the ear cavity (that is, an appropriate measurement state cannot be ensured), the radiation from the temperature measurement site in the ear cavity cannot be properly detected. In the case of infrared rays, the measurement error becomes larger

no. 1 Embodiment approach

[0034]

[0035] First, the external appearance structure of the ear thermometer 100 of the first embodiment of the present invention will be described. figure 1 It is a figure which shows the external appearance structure of the ear thermometer 100 of the 1st Embodiment of this invention.

[0036] in figure 1 Here, 101 is a probe part, which is inserted into the ear cavity (external auditory meatus) in order to detect infrared rays radiated from the temperature measurement site in the ear cavity (preferably the tympanic membrane and / or its periphery). The probe part 101 has a cylindrical shape with an outer diameter of about 7 mm at the tip, so that it can be inserted into the ear cavity.

[0037] 102 is a probe support part, and the probe part 101 is supported on one surface. In addition, a finger fixing wall 103 is provided on the surface 111 opposite to the surface supporting the probe portion 101, and the finger fixing wall 103 defines the X-axis direction of the finger when ...

no. 2 Embodiment approach

[0090] In the above-mentioned first embodiment, the structure in which the ear thermometer 100 is attached to the finger of the examiner using the attaching parts (102 and 104) and the attaching straps 106, 108 is adopted, but the present invention is not limited to this, for example, It may be a structure for installation through a finger-type installation part. In addition, in the first embodiment described above, when the ear thermometer 100 is installed, the probe support portion 102 and the fixing portion 104 are located on the same side (that is, the probe portion 101 and the fixing portion 104 are located on the same side), but the present invention does not Limited to this, for example, the probe part and the fixing part may be arranged on different sides. Hereinafter, an ear-type thermometer having a finger-cuff type attachment part and arranged so that the probe part and the fixing part are located on opposite sides during attachment will be described.

no. 3 Embodiment approach

[0118] In the first and second embodiments described above, the measurement start switch 203 (or 823) is arranged on the side surface of the fixed portion 104 (or the main body portion 803). However, when the subject is an infant or the like, when the body temperature is measured, fingers other than the finger on which the ear thermometer 100 or 800 is attached are used to hold the subject. Therefore, in a state where the probe section 101 (or 801) is inserted into the ear cavity, it is not always easy to press the measurement start switch 203 (or 823).

[0119] Therefore, in the ear thermometer of the present embodiment (referred to as ear thermometer 1200), when the probe portion is reliably inserted into the ear cavity, it is configured to detect this and automatically start the measurement. Hereinafter, the details of this embodiment will be described.

Abstract

Disclosed is an ear thermometer capable of easy and accurate insertion of a probe into a subject's aural cavity. The disclosed ear thermometer is provided with a temperature detection element and an infrared detection element, and by using the ambient temperature detected by said temperature detection element and the relative temperature detected by said infrared detection element, the ear thermometer (100) measures the subject's body temperature. The ear thermometer is provided with: a probe (101) which is configured from a hollow tubular body and inserted into the aural cavity; and mounting units (102, 104) which have mounting features (106-108) for mounting on a finger of the subject and which support the probe so that the support position of the probe (101) opposes the palmar surface of the subject's distal phalanx when mounted on the subject's finger using said mounting features (106-108).

Description

Technical field [0001] The invention relates to an ear type thermometer. Background technique [0002] Conventionally, the following ear thermometers have been used in which a probe is inserted into the ear cavity to detect the temperature of the tympanic membrane or its surroundings, thereby measuring the subject's body temperature. [0003] Generally, an ear thermometer has: a temperature detection element (for example, a thermistor) that detects the ambient temperature, and an infrared detection element (for example, a thermistor) that detects infrared rays radiated from a temperature measurement site (tympanic membrane or its periphery) in the ear cavity A thermocouple consisting of a cold junction and a hot junction), and calculates the subject’s body temperature based on the detection temperature of each detection element. Compared with other types of thermometers, the ear thermometer has the ability to accurately measure the body temperature in a short time Determine this a...
