Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings used for the following description, scales are appropriately changed so as to draw components in recognizable sizes.

[0042] figure 1 is a perspective view showing the sensor 1 of the first embodiment of the present invention. A sensor 1 attached to a living body (subject) includes a sensor body 10 and a cable 20 . Sensor 1 is used as a probe for a pulse oximeter.

[0043] The sensor body 10 has a clip-like shape, and is configured to be able to clip a part of the subject's body (fingertip, earlobe, etc.). The sensor body 10 includes a light emitter 11 and a light detector 12 . The light emitter 11 is configured to emit red light and infrared light. The light detector 12 is configured to output a signal corresponding to the intensity of light passing through the subject's body part clamped by the sensor body 10 .

Abstract

A sensor attached to a living body includes a sensor body that outputs a signal corresponding to biological information, and a cable that is connected to a sensor body and transmits the signal. The cable has a first portion having a first flexibility and a second portion having a second flexibility lower than the first flexibility. The second flexibility enables the second portion to be bent, and is able to retain a shape of the second portion in a bent state.

Description

technical field [0001] The present invention relates to a sensor attached to a living body to detect biological information, and also relates to a shape retainer attached to a cable for transmitting a signal corresponding to the biological information. Background technique [0002] When a cable connected to a sensor attached to a living body (subject) is in a freely swingable state, noise may be caused to enter a signal transmitted through the cable. Therefore, an operation of fixing the cable to the skin of the subject with tape is sometimes performed. Alternatively, a sensor in which a fixture having a predetermined shape is attached to a cable is sometimes used (see Patent Document 1, for example). The fixation device is secured to a part of the subject's body to prevent the cable from swaying. [0003] [Patent Document 1] JP-UM-A-7-028502 Contents of the invention [0004] In the case where the subject has sensitive skin, there is a possibility that the skin may bec...
