Abstract
A blood pressure monitor configured to removably mount to a cuff in a substantially symmetrical position with respect to a width of the cuff can include a housing defining an interior, a first port, and a second port. The first port can: secure to a first prong of the cuff when the cuff is mounted in a first orientation; receive and secure to a second prong of the cuff when the cuff is mounted in a second orientation; and enable fluid communication between the interior and at least one of a first fluid passage within the first prong and a second fluid passage within the second prong. The second port can: secure to the second prong of the cuff when the cuff is mounted in the first orientation; and receive and secure to the first prong of the cuff when the cuff is mounted in the second orientation.
Core Innovation
The invention relates to an ECG system having separable reusable and disposable portions. A reusable hub is configured to interface with external and/or internal ECG electrodes through conductor pins and flexible circuits, while the disposable portion provides a mating interface to establish power and data transfer. The ECG device construction includes authorization verification for coupling and/or operation, using encoded memory and/or contacts, and the reusable portion includes sensor functions such as temperature sensing and motion sensing, together with waterproofing.
The reusable hub includes a processor and memory and multiple temperature sensors placed at different locations within the hub. The system powers the electrodes, collects raw ECG data and raw temperature data, and uses the temperature sensor information to determine a body temperature parameter for subsequent physiological parameter determination. To protect the reusable hub during high-voltage events, the hub positions resistors between the circuit board and the conductor pins, with optional electrical isolation walls separating the resistors, and includes a metal heat sink for thermal regulation.
The document also describes patient-monitoring system cabling, including indirect/bypass cabling to reduce cable length between components. An alternative embodiment uses a disposable dock with a reusable hub and describes thermal and electrical isolation materials and structures for temperature sensing, together with packaging and securement structures to support proper placement of the device portions. It additionally references a blood pressure monitoring arrangement with cuff and port/prong concepts, independent fluid paths, and inflation and deflation behavior.
Claims Coverage
The provided independent claims define two related aspects of the blood pressure cuff: a cuff geometry and prong/port arrangement enabling two orientations with substantially symmetrical monitor mounting, and a cuff configured to removably secure to a user and be mounted on a blood pressure monitor with two independent fluid passages providing independent fluid communication with an inflatable interior. Across the two independent claims, a total of 5 main inventive features are identified.
Orientation-swappable prong mounting for substantially symmetrical monitor placement
A blood pressure cuff is configured to removably secure to a user in a first orientation and a second orientation, and to allow a blood pressure monitor to be removably mounted in a substantially symmetrical position with respect to a width of the blood pressure cuff, including a first prong and a second prong that reversibly engage different monitor ports depending on orientation.
Two prongs with independent fluid passages communicating with the interior
The blood pressure cuff includes a bladder at least partially defining an interior configured to be inflated and deflated, with each of the first and second prongs comprising a respective fluid passage in fluid communication with the interior, so that the first and second fluid passages provide independent fluid communication with the interior.
Cuff geometry with width smaller than length for arm wrapping and mounting
The blood pressure cuff includes a bottom surface configured to face towards skin and is configured to be wrapped around and secured to an arm of the user, with a width extending between the first and second sides wherein the width is smaller than the length.
Two mechanical mounting points using first and second prongs
The blood pressure cuff includes two prongs extending above the top surface, where the first and second prongs provide two mechanical mounting points for the blood pressure monitor.
Independent fluid communication with inflatable interior via first and second prongs
The blood pressure cuff includes an inflatable interior, a first prong comprising a first fluid passage in fluid communication with the inflatable interior, and a second prong comprising a second fluid passage in fluid communication with the inflatable interior, where each of the first and second fluid passages provides independent fluid communication with the inflatable interior.
Across the independent claims, the inventive coverage centers on a blood pressure cuff configured for arm wrapping and monitor mounting using two prongs that establish mechanical mounting points and independent fluid pathways, with cuff geometry defined by width smaller than length and, in one independent claim, a first-versus-second orientation that swaps prongs into corresponding monitor ports for substantially symmetrical placement.
