  • Publication number: 20180242900
    Abstract: A swallowing movement monitoring sensor which measures swallowing movement of a subject includes an outside shape variation sensor attached to a laryngeal portion of the subject and a microphone attached in an ear of the subject. The outside shape variation sensor includes an optical fiber sheet. The optical fiber sheet detects variation in quantity of transmitted light based on a loss caused by a lateral pressure applied to an optical fiber from the laryngeal portion in association with variation in outside shape of the laryngeal portion involved with swallowing movement. The microphone detects swallowing sound produced in the ear in association with swallowing movement.

  • Patent number: 8282813
    Abstract: A biosensor measurement device for providing accurate measurement results within a short period of time by using only a very small amount of sample. The biosensor measurement device includes a power source, which is connected to a voltage regulator, a measurement instrument, and a controller for supplying power. When the biosensor chip is connected to the biosensor measurement device and a voltage is applied, the measurement instrument begins the measurement of a current value for the biosensor. When the measured current value or a measured charge value is greater than a reference value, the measurement is terminated in accordance with an instruction issued by the controller, and when the value is smaller than the reference value, the measurement is continued in accordance with a controller instruction.

  • Publication number: 20100069792
    Abstract: A biosensor cartridge capable of performing puncturing in an exact position, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When tip portion 11a of biosensor chip body 11 is pushed against a subject M, elastic body 20 protruding from a tip portion 11a of biosensor chip body 11 is compressed, and puncturing tool 12 for puncturing protrudes. Thus, the subject M can be punctured. Additionally, if a pushing force is weakened, puncturing tool 12 is extracted from the subject M by the restoring force of elastic body 20, and the sample R flows out of the puncture hole. Additionally, cover member 19 is provided around biosensor chip body 11. Thus, when puncturing is performed by thin plate-shaped biosensor cartridge 10, biosensor chip body 11 can be prevented from deforming, and puncturing can be accurately performed in a desired puncturing position.

  • Publication number: 20100004559
    Abstract: A biosensor cartridge capable of making the collected amount of a sample required for measurement into a small quantity to reduce a user's burden, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When one end portion of biosensor chip is pushed against subject, elastic body is compressed, and puncturing tool can protrude and perform puncturing. Additionally, if a pushing force is weakened, puncturing tool is extracted from subject by the restoring force of elastic body, and blood (sample) flows out of the puncture hole. In this case, since the puncture hole, and sample collection opening provided at biosensor chip are contained in enclosed half-open space formed by elastic body, even a small amount of blood (sample) can also be easily collected.

  • Publication number: 20090299225
    Abstract: There is provided a biosensor chip where the collecting amount necessary for the measurement is made small whereby burden of a user is reduced and, at the same time, a sample at a puncture opening is able to be easily collected and measured without an operation of making the sample collection opening nearer the puncture opening. When an end of a main body chip is pushed onto a test body, an elastic body installed at an end of the main body chip is compressed and a device for puncture is produced whereby the test body is able to be punctured. When the pushing force is made weak, the device for puncture is pulled out from the test body due to resilience of the elastic body and a sample is flown out from the puncture opening.
