Abstract
A cuff for monitoring physiological cycles has an exterior and interior surface and securing means. The cuff consists of a body having an upper curve, a lower curve and a height (CH) therebetween. A sensor adhered with a flexible protective overlay to the interior surface is in communication with a microprocessor storage means. The microprocessor storage means can be within the cuff or separate therefrom with communication between the sensor and the storage means being wireless or through a communication member. A locking tab, having a width less than the body, extends from one side of the body. A slot retaining area extends from the body on a side opposite the locking tab and contains a slot dimensioned to receive the locking tab. A pull tab is adjacent the slot retaining area opposite the body. The pull tab shares a base with the slot retaining area and has a top line and an end width less than the width of the body. The cuff can be manufactured from a hook and loop material or have other securing methods to affix the cuff in place.
Core Innovation
A cuff for monitoring physiological cycles includes a body having an upper curved edge, a lower curved edge, an exterior surface, and an interior surface. A sensor is adhered to the interior surface and is configured to be placed adjacent a user's artery, and the sensor is in communication with a microprocessor storage device for monitoring physiological cycles.
The cuff includes a locking tab extending from the body and a slot retaining portion extending from an opposite side of the body than the locking tab, where the slot is configured to receive the locking tab. A pull tab extends from the slot retaining portion in a direction away from the body, and the locking tab and pull tab are each configured to be pulled in opposite directions to secure the body relative to the user's artery.
The cuff configuration uses relative tab widths between the upper and lower curved edges of the body and between the upper and lower edges of the pull tab. A protective overlay may protect the sensor, and the cuff can be dimensioned and angled such that the locking tab extends from a centerline of the body at an angle, the slot is disposed within the slot retaining portion at an angle relative to a lower edge of the slot retaining portion, and the upper edge of the pull tab is disposed at an angle relative to the lower edge of the pull tab.
Claims Coverage
The independent claims are directed to three inventive features: a cuff construction for monitoring physiological cycles, a cuff with specified geometry and protective overlay, and a method of noninvasively monitoring hemodynamic parameters. Across the independent claims, the inventive features center on a sensor adhered to an interior surface with a locking tab and pull tab arrangement, including a slot-retaining portion, for securing the cuff relative to a user's artery, together with transmitted sensor data indicating arterial blood pressure or other hemodynamic parameters.
Cuff with sensor adhered to interior surface and opposite-direction securing using locking tab and pull tab
A cuff includes a body with upper and lower curved edges and an interior surface; a sensor adhered to the interior surface and in communication with a microprocessor storage device; a locking tab extending from the body; a slot retaining portion defining a slot configured to receive the locking tab; and a pull tab extending away from the body, where the sensor is configured to be placed adjacent a user's artery, and the locking tab and the pull tab are configured to be pulled in opposite directions to secure the body relative to the user's artery.
Cuff with specified geometry and protective overlay for arterial adjacent placement
A cuff for monitoring physiological cycles includes a body with upper and lower curved edges and a sensor adhered to an interior surface in communication with a microprocessor storage device; an overlay protecting the sensor; a locking tab with specified width; a slot retaining portion defining a slot; and a pull tab extending from the slot retaining portion in a direction away from the body, with the locking tab extending from a centerline at an angle and the slot disposed at an angle, and the pull tab disposed at an angle relative to the lower edge, for securing the cuff relative to a user's artery.
Noninvasive hemodynamic monitoring using cuff-adjacent sensor and opposite-direction tightening
A method of noninvasively monitoring at least one hemodynamic parameter includes placing a sensor having a communication member contained in the interior of a cuff body adjacent a user's artery; threading a locking tab extending from the cuff body through a slot within a slot retaining portion; applying pressure in opposite directions to the locking tab and a pull tab to tighten a cuff; and adhering the locking tab and the pull tab to the cuff body, with transmitted sensor data indicating arterial blood pressure.
Overall, the independent claims require a cuff with a sensor adhered to the interior surface and a locking tab received in a slot with a pull tab, where the tab and pull tab are pulled in opposite directions to secure the cuff relative to a user's artery. The method claim further requires threading the locking tab through the slot, tightening by opposite-direction application to the locking tab and pull tab, adhering the tab and pull tab to the cuff body, and using transmitted sensor data to indicate arterial blood pressure as at least one hemodynamic parameter.
