Problems solved by technology

However, it is difficult to span the entire flow range with conventional pumps, from the smallest cuffs (such as those in neonatal subjects) to the largest cuffs (such as a thigh cuff in adults)
Furthermore, currently, the only technology aimed at addressing this requires the addition of additional hardware components to the iNIBP measurement setup, which can be complex

Embodiment Construction

[0029] Provided herein is a cuff (or clamp unit) for use with a non-invasive blood pressure (NIBP) measurement device, or more specifically, an inflation-based non-invasive blood pressure (iNIBP) measurement device, which overcomes the Regarding limitations of prior art.

[0030] The cuffs described herein may be wearable cuffs. That is, the cuffs described herein may be configured to be worn on or around (eg, wrapped around, attached to, or secured to) a measurement site of a subject (eg, a patient). The measurement site of the subject referred to herein may be any part of the subject's body suitable for use in measuring the subject's blood pressure, such as any part of the subject's body including an artery. For example, a measurement site of a subject referred to herein may be positioned on a limb of the subject, such as an arm of the subject (eg upper arm or forearm) or a leg of the subject (eg thigh). Accordingly, the cuffs described herein may be configured to be worn ...

Abstract

There is provided a cuff (10) for use with an inflation-based non- invasive blood pressure, NIBP, measurement apparatus. The cuff (10) comprises an inlet (12) configured to be coupled to an outlet of the inflation-based NIBP measurement apparatus to receive a flow of fluid and a bladder (14) coupled to the inlet (12) and inflatable to pressurize a measurement site of a subject by receiving the flow of fluid. The cuff (10) also comprises a valve (16) disposed along a flow path between the inlet (12) and the bladder (14) or disposed on the bladder (14). The flow resistance of the valve (16) is such that the valve (16) passes part of the flow of fluid received in the bladder (14) to the atmosphere in order to inflate the bladder (14) at a required flow rate for inflating the cuff.

Description

technical field [0001] The present disclosure relates to a cuff for use with an inflation-based non-invasive blood pressure (NIBP) measurement device. Background technique [0002] Blood pressure (BP) or more precisely arterial blood pressure is the pressure exerted by circulating blood on the walls of arterial vessels. It is one of the key vital signs to establish the health of a patient, and therefore requires monitoring of endangered patients. Blood pressure is a periodic signal, rising with each contraction of the heart and falling between heartbeats. Blood pressure is usually described by systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial blood pressure (MAP), where systolic blood pressure is the maximum blood pressure during the cardiac cycle, diastolic blood pressure is the minimum blood pressure during the cardiac cycle, and mean arterial blood pressure is Average blood pressure during a cardiac cycle. [0003] There are different tec...
