The sphygmomanometer according to the present invention measures blood pressure in accordance with an oscillation in an artery wall, resulting from an arterial pulse correspondent with a change in cuff pressure. It comprises a cuff that is connected to the sphygmomanometer main body by a tube, a display unit for displaying the results of blood pressure measurements, and an air supply unit for supplying air to, and thus pressurizing, the cuff, which is detachable from the sphygmomanometer main body. The air supply unit is screwed into the sphygmomanometer main body with a screw assembly, and the screwed-in state is preserved by a caulking ring. The air supply unit also comprises a filter for keeping dust from entering the sphygmomanometer main body. | 12-18-2008 |
20090036786 | AUTOMATIC ANKLE BRACHIAL PRESSURE INDEX SYSTEM - An ABPI measurement system includes two cuffs for each ankle and two cuffs for each arm of a patient. Each cuff has chambers. The four cuffs are applied to each limb (or finger or toe), each chamber is inflated simultaneously to a pressure until a Pneumo Arterial Plethysmography (PAPG) signal related to the arterial flow in the limb is detected at the chambers. The chambers are then simultaneously inflated until the PAPG signals are extinguished in each limb, the inflation of chambers continuing for 10 mmHg to 20 mmHg above that pressure. The chambers are then deflated and the pressure at which the PAPG signal returns in the first chamber is recorded for each limb and this value of the pressure is used to calculate the ABPI. The ABPI is displayed or sent to a remote site. | 02-05-2009 |

20100292586 | Wireless automatic ankle-brachial index (AABI) measurement system - A central processor controlled system and test procedure for independently, contemporaneously and plethysmographically monitoring arterial blood pressure at a subject's arms and legs. Micro-controlled occluding and sensing cuffs containing sensors are inflated and deflated at each limb of a supine patient.

Second scoring and fittings about the lowest pressure point at the DC sensor data and original occluding cuff pressure data identify each limb's systolic pressure. The derived systolic limb pressure values are then processed to determine right and left ABI values. | 11-18-2010 |
