Fluid bladder, blood pressure measurement cuff, blood pressure monitor, and blood pressure measurement method
A blood pressure measurement method includes wrapping a cuff around a site. The cuff includes: a first bladder that swells due to receiving fluid and is arranged at an outer surface of the site that corresponds to a first half surface where an artery is; and a second bladder that swells due to receiving fluid and is arranged at the outer circumferential surface of the measurement site that corresponds to a second half surface opposite to the first half surface. During inflation, the pressure of the second bladder is made larger than the first bladder by supplying more fluid such that the stroke amount by which the second fluid bladder swells is larger in the thickness direction. Then, the two bladders are inflated at equal rates. In the process of inflating, or in the process of deflating at rates equal to each other after inflating, blood pressure is measured.
SELF-CALIBRATING SYSTEMS AND METHODS FOR BLOOD PRESSURE WAVE FORM ANALYSIS AND DIAGNOSTIC SUPPORT
Indirect, oscillometric, digital blood pressure monitoring systems and methods enabling self-calibration to obtain absolute blood pressure values using algorithmic analysis of arterial pressure pulses to establish an oscillometric profile and compensate for intervening effects on digital arterial pressure. Proper algorithmic analysis is dependent upon proper positioning and maintained engagement of a digital cuff on the digit of a user and subsequent hydraulic coupling of the cuff to the arteries within the digit.

BLOOD FLOW OCCLUSION DEVICES AND METHODS THEREOF
A blood flow occlusion system includes an inflator and a pressure regulator coupled to a pressure cuff and a computing device coupled to the inflator and the regulator. The computing device comprises a memory coupled to the processor which is configured to be capable of executing programmed instructions stored in the memory to: determine brachial occlusion data based on calculating the brachial occlusion data with an occlusion regression equation using one or more input diagnostic parameters associated with a client; generate treatment parameters of a treatment program to treat the condition of the client based on the optimized brachial occlusion data and an obtained stage of the condition; generate programmed instructions of control commands to manage operation of the pressure cuff, inflator, and pressure regulator based on the treatment parameters; and initiate execution of the programmed instructions for the treatment program for treating the condition of the client when engaged.

Systems and methods for blood pressure measurements
A monitoring system configured to measure the user's health-related parameters while in a certain state is disclosed. Based on whether the user is in the certain state and/or one or more criteria being met, the monitoring system can perform a physiological measurement such as a blood pressure measurement. The monitoring system can be capable of dynamically adjusting the measurement parameters, criteria, and acquired information based one or more scalers. The criteria can be based on user states or conditions such that user disruptions can be reduced and the measurement accuracy and/or efficiency can be enhanced. The monitoring system can also measure the user's parameters during the measurement and may abort the measurement if the measurement may not have accurate information and/or to reduce any disruption to the user. Alternatively, the measurement can be annotated so that the measurement can be used during data interpretation with certain qualifiers attached.
Systems and Methods For Monitoring a Patient
A system for monitoring a patient includes an inflatable cuff configured to at least partially occlude an artery of the patient, and a sensor configured to determine a first parameter associated with the at least partially occluded artery and to generate an output signal indicative of the first parameter.

Monitoring Treatment of Peripheral Artery Disease (PAD) Using Diffuse Optical Imaging
A plurality of modules are simultaneously positioned at locations that correspond to different angiosomes. Each of these modules has a front surface shaped and dimensioned for contacting a person's skin, a plurality of different-wavelength light sources aimed in a forward direction, and a plurality of light detectors aimed to detect light arriving from in front of the front surface. Each module is supported by a support structure (e.g., a strap or a clip) that is shaped and dimensioned to hold the front surface adjacent to the person's skin at a respective position. Perfusion in each of the angiosomes is monitored using these modules, and the surgeon can rely on this information to guide his or her intervention.
