  • Temperature-resistant sugar-responsive gel
    Patent number: 11819570
    Abstract: A sugar-responsive gel that is highly resistant to temperature changes, and a sugar-responsive drug delivery device including such a gel. The sugar-responsive gel, which comprises a gel composition including a monomer having a hydroxyl group in addition to a phenylboronic-acid-based monomer, can exhibit suitable temperature resistance. A sugar-responsive drug delivery device including such a sugar-responsive gel is less susceptible to the effects of temperature changes, and therefore can prevent undesirable excessive delivery of a drug such as insulin.
    Type: Grant

  • Coupling/uncoupling device
    Patent number: 11518550
    Abstract: A coupling/uncoupling device includes a columnar member configured by a divided pair of semicircular members, and a pair of coupling members forming a circular holding section that holds the columnar member. The circular holding section includes a circular inner surface section with which an outer circumferential surface of the columnar member is in slide contact, the circular inner surface section being formed from inner circumferential surfaces of a semicircular section in one coupling member and a semicircular section in the other coupling member. The columnar member is configured to be rotatable in both clockwise and counterclockwise directions along the circular inner surface section about a reference position where a contact surface of the pair of coupling members and a dividing surface of the columnar member are flush with each other.
