Abstract
A fluid circuit of a blood pressure measurement device includes a first cuff connected to a secondary side of a pump that supplies a fluid to a secondary side, a second cuff connected to a secondary side of the first cuff, a first valve provided between the first cuff and the second cuff, the first valve that closes when a differential pressure between the first cuff and the second cuff reaches a predetermined differential pressure, and a fluid resistor provided between the first valve and the second cuff.
Claims5
A fluid circuit, comprising:
- a first cuff connected to a secondary side of a pump that supplied a fluid to said secondary side of the pump;
- a second cuff connected in series to a secondary side of the first cuff, such that fluid flows sequentially from the pump to the first cuff, then to the first valve, then to a fluid resistor, and then to the second cuff.
