By a News Reporter-Staff News Editor at Hematology Week -- According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventors Pei, Cheng-Wei (Belmont, CA); Sthalekar, Chirag C. (Medford, MA), filed on April 30, 2014, was made available online on March 19, 2015 (see also Maxim Integrated Products, Inc.).
The assignee for this patent application is Maxim Integrated Products, Inc.
Reporters obtained the following quote from the background information supplied by the inventors: "Blood pressure, sometimes referred to as arterial blood pressure, is the pressure exerted by circulating blood upon the walls of blood vessels and is one of the principal vital signs. During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure. The blood pressure in the circulation is principally due to the pumping action of the heart. Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation. The rate of mean blood flow depends on the resistance to flow presented by the blood vessels. Mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy."
In addition to obtaining background information on this patent application, NewsRx editors also obtained the inventors' summary information for this patent application: "A mobile blood pressure monitor is described that includes an integrated acoustic device, an optical sensor including at least one of a light source or a pulse oximeter device, and control circuitry coupled to the integrated acoustic device and the optical sensor. Additionally, a mobile electronic device configured to measure blood pressure is described that includes a mobile system and a mobile blood pressure monitor as disclosed above. In implementations, a process for measuring blood pressure includes sensing a heart sound with an integrated acoustic device, measuring a blood pulse rate at a peripheral site with an optical sensor, calculating a pulse wave transit time using a sensed heart sound and a measured blood pulse rate, and correlating a blood pressure using the heart sound and the blood pulse rate.
"This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
"The detailed description is described with reference to the accompanying figures. The use of the same reference numbers in different instances in the description and the figures may indicate similar or identical items.
"FIG. 1A is an isometric front view illustrating a mobile blood pressure monitor in accordance with example implementations of the present disclosure.
"FIG. 1B is an isometric rear view illustrating a mobile blood pressure monitor in accordance with example implementations of the present disclosure.
"FIG. 1C is a partial bottom view illustrating a mobile blood pressure monitor in accordance with example implementations of the present disclosure.
"FIG. 1D is a graphical illustration of a heart sound measurement and a blood pulse rate using a mobile blood pressure monitor in accordance with example implementations of the present disclosure.
"FIG. 1E is an environmental illustration of a mobile blood pressure device and a mobile blood pressure monitor in accordance with example implementations of the present disclosure.
"FIG. 2 is a flow diagram illustrating a process in an example implementation for utilizing a mobile blood pressure monitor, such as the mobile blood pressure monitors shown in FIGS. 1A through 1E."
