CITIZEN SYSTEMS Co., Ltd. will launch the upper arm blood pressure monitor 'CHUH904C' featuring a new design called the "Kapputto Cuff" in early June 2023.
The U-shaped "Kapputto Cuff" does not require threading through the arm, allowing it to be easily attached with one hand while maintaining a comfortable position. It reduces the burden during measurements and supports daily blood pressure monitoring more easily. The CHUH series has received favorable reviews with its prior release targeted at medical institutions, and it won the 2022 Good Design Award for its new cuff design and compact storage capability.
