Problems solved by technology

[0011] However, variations in inflation velocity may cause artifacts (or transient effects) in the signal, which render a portion of the signal around the variation in inflation velocity unusable for determining blood pressure
This can negatively affect the accuracy of blood pressure measurements, especially if velocity changes (and thus, artifacts) occur near the maximum oscillation amplitude or at oscillation amplitudes related to systolic or diastolic blood pressure
In the worst case, a successful measurement may not be performed due to the induced artifacts (e.g. the measurement may be stopped early due to the induced oscillations), or the measurement result may be incorrect due to the induced artifacts, This can lead to wrong diagnoses

Embodiment Construction

[0036] Provided herein is a device for controlling a wearable cuff (or clip unit) used in measuring blood pressure that overcomes the limitations associated with the prior art. The wearable cuffs referred to herein are inflatable to pressurize the measurement site of the subject (eg, patient). In this way, the wearable cuff can pressurize the artery in the subject's measurement site. Typically, a wearable cuff may be provided with a fluid (eg, a gas such as air or any other fluid) suitable for inflating the wearable cuff. The wearable cuff may be inflatable to pressurize the measurement site of the subject (and thus, the artery in the measurement site of the subject) under the pressure of the fluid in the wearable cuff.

[0037] The wearable cuff is configured to be worn on or around (eg, wrapped around, attached to, or tied to) a measurement site of a subject. The measurement site of the subject may be any part of the subject's body suitable for use in measuring the subject...

Abstract

There is provided an apparatus (12) for controlling a wearable cuff (14) for use in measuring blood pressure, wherein the wearable cuff (14) is inflatable to pressurize a measurement site of a subject(18). The apparatus (12) is configured to initiate the inflation of the wearable cuff (14) at a first inflation speed and change the first inflation speed during inflation of the wearable cuff (14).The first inflation speed is changed at a rate that is limited to a maximum value.

Description

technical field [0001] The concept relates to an apparatus and method for controlling a wearable cuff used in measuring blood pressure. 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 used to confirm a patient's health, and therefore needs to be monitored for at-risk patients. Blood pressure is a periodic signal that rises with each contraction of the heart and falls between heartbeats. It is usually described by systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP), where systolic blood pressure is the maximum blood pressure during the cardiac cycle and diastolic blood pressure is the minimum blood pressure during the cardiac cycle, Mean arterial pressure is the average blood pressure during the cardiac cycle. [0003] There are different techniques by which blood pressure c...
