Claims

[Scope of Claim for Utility Model Registration] 1. An oscillometric blood pressure monitor that measures blood pressure at the base of the fingers (left index finger and middle finger).
When measuring blood pressure, the cuff must be able to sufficiently compress the entire circumference of the target finger base. For this reason, the compression cuff covers the circumference of the finger, but must have sufficient capacity to ensure reliable compression depending on the thickness of the finger.
On the other hand, however, in order to stably detect subtle changes in the volume of the finger as pressure changes due to compression of the cuff, it is disadvantageous if the cuff capacity is too large, considering the compressibility of air. For this reason, by separating the compression cuff with stable volume changes and the pressure detection cuff, it is possible to simultaneously perform sufficient compression and stable detection of volume changes. 2. When measuring blood pressure with a finger, the blood pressure at the base of the finger shows the closest value to that measured at the upper arm. Therefore, the cuff must be securely attached to the base. The conventional method required the person taking the measurement to fully insert their finger into the cuff, but this device has a shape that allows the weight of the device to fit naturally in the palm of the hand with a well-balanced center of gravity. Therefore, when the measurer places this device on the palm of his/her hand, the cuff naturally comes into close contact with the base of the finger.
Since blood pressure value data can be read in the same position, the shape is such that errors in hydrostatic pressure caused by movement are less likely to occur.
