Abstract
A low-profile blood pressure measurement system and methods of use are disclosed. The system includes an expandable member or structure that has a multi-compartment structure and/or is mounted on a rigid surface or structure. The system is incorporated into a portable multi-function device, or is configured to communicate with a portable multi-function device.
Claims20
A blood pressure measurement system, comprising:
- a device housing configured to be worn by a user and at least partially containing:
- a display screen;
- a pressure sensor;
- and
- an expansion actuator;
- a controller configured to control operation of the expansion actuator;
- and
- an expandable member coupled to the device housing and configured to at least partially engage a circumference of a limb, thereby securing the device housing to the user, the expandable member having a plurality of expandable cells comprising:
- a first set of expandable cells each having an inner surface facing the limb of the user, and an outer surface opposite the inner surface;
- a second set of expandable cells stacked with the first set of expandable cells and at least partially extending around the outer surface of the first set of expandable cells;
- wherein:
- operation of the expansion actuator controls a pressure within at least one of the first or second sets of expandable cells;
- the pressure sensor is configured to output a signal indicative of a blood pressure of the user;
- and
- the display screen is configured to display a visual output associated with the blood pressure of the user.
12 more elements
A wearable device for measuring blood pressure, comprising:
- a housing;
- a display at least partially within the housing;
- a controller;
- a wristband configured to at least partially encircle a limb of a user, thereby coupling the housing to the user, and having multiple inflatable cells that encircle the limb, the multiple inflatable cells comprising:
- a first set of inflatable cells having an inner surface facing the limb of the user, and an outer surface opposite the inner surface;
- a second inflatable cell stacked with the first set of inflatable cells and at least partially extending around the outer surface of the first set of inflatable cells;
- an air pump operably connected to at least one inflatable cell of the multiple inflatable cells, the air pump configured to increase a pressure within the at least one inflatable cell at least partially in response to receiving a first signal from the controller;
- a valve coupled to the at least one inflatable cell and configured to release air from the at least one inflatable cell at least partially in response to receiving a second signal from the controller;
- and
- a pressure sensor configured to measure the pressure within the at least one inflatable cell and output a third signal to the controller indicative of the pressure within the at least one inflatable cell;
- wherein the wearable device is configured to estimate a blood pressure of the user at least partially in response to at least one of the first signal, the second signal, or the third signal.
8 more elements
A blood pressure measurement device, comprising:
- a band configured to be worn around a limb of a user, the band comprising multiple expandable cells coupled together to engage a circumference of the limb, wherein the multiple expandable cells comprise:
- a first set of expandable cells having an inner surface facing the limb of the user, and an outer surface opposite the inner surface;
- a second set of expandable cells stacked with the first set of expandable cells and at least partially extending around the outer surface of the first set of expandable cells;
- a pressure sensor coupled with at least one of the multiple expandable cells, the pressure sensor configured to detect a fluid pressure within the at least one of the multiple expandable cells and output a first signal indicative of the fluid pressure;
- and
- a housing coupled to the band and containing a controller configured to receive the first signal and estimate a blood pressure of the user;
- and
- a display at least partially contained by the housing and configured to display a visual output indicative of the blood pressure of the user.
