Measuring apparatus and measurement method
First Claim
1. A measuring apparatus that measures numeric information about a substance contained in at least one carrier selected from subcutaneous interstitial fluid and blood, comprising:
- a sensor section having a sensor outputting a signal in accordance with the numeric information, a support film that supports the sensor, and an adhesive film that affixes the sensor section to the skin; and
a computing section that is disposed on a garment of a user utilizing said measuring apparatus and receives the signal outputted by the sensor and performs computational processing based on the signal,the sensor comprising a deployed portion deployed under the skin and a base portion disposed over the surface of the skin, andthe computing section being disposed so as to be isolated from the sensor section, whereinwhen the deployed portion extends not through the adhesive film but through the support film and the base portion is disposed on the support film, the sensor is supported by the support film and the deployed portion is deployed under the skin,the sensor section comprises, as the adhesive film, two or more pieces of adhesive film having a first adhesive layer on one side, andthe two or more pieces of adhesive film are strip-like in shape and are capable of adhesion to both said sensor section and the skin through the medium of the first adhesive layer of the adhesive film in respectively different locations on an upper face of said sensor section,wherein the computing section communicates with the sensor section via wireless communication,wherein the sensor section includes a water impermeable film having a second adhesive layer on one side, and the water impermeable film is formed so as to prevent the ingress of moisture to the base portion when it covers the base portion with the second adhesive layer facing the base portion, the second adhesive layer of the water impermeable film being configured to be in contact with the skin, andthe sensor section includes a signal transmitting unit connected to the sensor through a wire, and the signal transmitting unit is not covered by the water impermeable film.

Abstract
Disclosed is a measuring device for obtaining numerical information concerning a substance present in the interstitial subcutaneous fluid, the device being equipped with a sensor unit that outputs signals in accordance with the numerical information concerning the substance and an arithmetic unit (control unit) that receives the signals outputted from the sensor unit and arithmetically processes the signals. The sensor unit is equipped with a sensor, some of which is punctured into the skin. The arithmetic unit (control unit) has been disposed so as to be separate from the sensor unit.
