  • Patent number: 11045119
    Abstract: The present disclosure relates to a biosensor for measuring glucose in a biological sample, which contains a filter unit formed of a cytoplasmic membrane, which allows selective permeation of glucose in a biological sample. The biosensor of the present disclosure, which contains the cytoplasmic membrane filter unit allowing selective permeation of glucose in the biological sample, exhibits high glucose detection sensitivity as compared to the commercially available blood sugar measuring sensors and also exhibits high glucose detection specificity despite the addition of signal-interfering substances such as fructose, xylose, maltose, cysteine, ascorbic acid, uric acid, galactose, etc. In addition, because he cytoplasmic membrane filter unit contained in the biosensor for measuring glucose of the present disclosure is not significantly affected by the moisture in the air, it can be applied to various products such as a disposable blood sugar test strip or an attachable or implantable glucose measuring device.

  • Publication number: 20210116448
    Abstract: The present disclosure relates to a method for measuring fibrinogen concentration in a blood sample, which enables measuring of the concentration of the fibrinogen protein present in a blood sample from the human body. The method for measuring fibrinogen concentration of the present disclosure is convenient because an enzyme is not used. In addition, an error due to a factor affecting factor affecting in-vivo enzyme activity does not occur and measuring time is decreased since measurement for reference plasma is unnecessary. Therefore, the method achieves superior accuracy, precision and reproducibility as compared to the existing technologies and can be usefully employed for measuring fibrinogen concentration in a blood sample.

  • Patent number: 10477002
    Abstract: A communication server includes a receiving unit receiving a conversation request signal including a phone number of a receiving terminal in a PSTN (public switched telephone network) via an IP network; a specifying unit specifying transmitting user information on a user using a transmission terminal transmitting the request signal, and assigning an address on the IP network to the transmission terminal; a first transmission unit transmitting the address and the request signal to a communication carrier having a gateway between the PSTN and the IP network; and a second transmission unit transmitting the phone number and the transmitting user information to a transfer server transferring information to a designated terminal.
