【0006】 [0006]

【作用】上記の構成によると、可撓性材料は熱伝導性がよいので、測定時にLEDから発する熱はその可撓性材料で構成された保持材を介して外部に放射され、被検者の皮膚面の温度の上昇を2〜3°C程度に軽減することができる。 According to the above structure [action], since the flexible material is good thermally conductive, heat generated from the LED during measurement is radiated to the outside through the holding material constituted by the flexible material, the subject the increase in temperature of the skin surface can be reduced to about 2 to 3 ° C for. 従って、被検者に低温やけどをおこさせることがなくなった。 Thus, no longer able to cause low temperature burn to the subject.

【0007】 [0007]

【実施例】以下、本発明のオキシメータプローブの一実施例を図面を参照して説明する。 EXAMPLES Hereinafter, a description will be given of an embodiment of an oximeter probe of the present invention with reference to the drawings.

【0008】図1及び図2に本発明の一実施例の構成を示す。 [0008] showing a configuration of an embodiment of the present invention in FIGS. 図において、シリコンゴム等の可撓性材料で構成された保持材1の片面には粘着層2が形成されており、 In the figure, on one side of the flexible material consists of a holding member 1 such as a silicon rubber is formed the adhesive layer 2,
粘着層2が形成された保持材1の片面には、ほぼT字状のフレキシブルプリント配線板3が接着されている。 One side of the adhesive layer 2 has been formed holding material 1, is substantially T-shaped flexible printed wiring board 3 is bonded. 配線板3の長手方向の両端にはそれぞれLED4とPD5 Each of the longitudinal ends of the wiring board 3 LED 4 and PD5
とが取り付けられており、それらのLED4及びPD5 Doo is attached, their LED4 and PD5
は配線板3に形成された配線パターン6,7がリード線となって、それぞれ保持材1の長手方向と直角の方向に導出されている。 Wiring patterns 6 and 7 formed in the wiring board 3 is a lead wire, which is led in the longitudinal direction at right angles with the direction of each holding member 1. また、ここではLED4が取り付けられた部分の粘着層2が剥離され、LED4が直接保持材1に接触した好ましい実施例を示している。 Also, here is peeled off the adhesive layer 2 of the portion LED4 is attached, it shows a preferred embodiment LED4 is in direct contact holding member 1.

【0009】次に本実施例の作用を図3を参照して説明する。 [0009] Next will be described the operation of this embodiment with reference to FIG. 保持材1は粘着層2を介して生体の皮膚11に接着固定される。 Holding material 1 is bonded and fixed to the living body skin 11 via the adhesive layer 2. このときLED4の発光面とPD5の受光面とは皮膚11に当接している。 It is in contact with the skin 11 to the light receiving surface of the light emitting surface and PD5 of LED4 this time. LED4を発光させると、LED4から発した光は皮膚11の組織を通り血管12を照射する。 When emit LED4, the light emitted from the LED4 irradiating through blood vessels 12 to the skin tissue 11. そして血管12内の血液により反射し、その反射光は再び皮膚11の組織を通ってPD5に入射する。 Then reflected by the blood in the vessel 12, the reflected light enters the PD5 through again the skin tissue 11. このとき血液を照射した光は血液の酸素飽和度に応じて吸収され、反射光の光量が変化する。 In this case light irradiated blood is absorbed according to the oxygen saturation of the blood, the amount of reflected light changes. 従って、PD5によって反射光の光量の変化を測定することにより、血液の酸素飽和度を測定することができる。 Thus, by measuring the change in quantity of reflected light by PD5, it is possible to measure the oxygen saturation of the blood.

【0010】上記測定時にLED4から熱が発生するが、この熱は熱伝導性のよいシリコンゴム等の可撓性材料で構成された保持材1を介して外部に放射されるので、LED4が接している部分の皮膚11の温度上昇を低減することができる。 [0010] Heat is generated from LED4 during the measurement, but since the heat is radiated to the outside through the retaining member 1 made of a flexible material such as a good silicone rubber thermal conductivity, LED4 is in contact the temperature rise of the skin 11 of that portion can be reduced. 従って、被検者の熱による低温やけどの発生を防いで正確な測定を行なうことができる。 Therefore, it is possible to perform accurate measurement by preventing the occurrence of low-temperature burn due to heat of the subject.

【0011】 [0011]

【発明の効果】以上説明したように、本発明のオキシメータプローブによれば、LEDから発する熱を保持材を介して外部に放熱するようにしたので、被検者の熱による低温やけどの発生を防いで、正確な測定を行なうことができる。 As described in the foregoing, according to the oximeter probe of the present invention, since the radiating heat generated from the LED to the outside through the retaining member, the occurrence of low-temperature burn due to heat of the subject preventing, it is possible to perform an accurate measurement.
