Caretaker 4

Press Releases

The Caretaker 4 wearable device is set to revolutionize patient care by using a patented algorithm and smart technology to provide continuous data for non-invasive blood pressure and vital signs monitoring from anywhere. Current methods of gathering blood pressure (BP) and other vital sign measurements have changed very little 
over the past 50 years. They either involve periodic spot-checks using manual devices or continuous monitoring via invasive arterial catheters. Traditional spot-check blood pressure measurements collected from arm cuff sphygmomanometers are inconsistent often unreliable, and can miss rapid changes in patient hemodynamic health. They capture only a single point in time, their measurements can be influenced by variable factors such as patient posture, physical motion, stress and recent food intake, and they are susceptible to errors in manual data entry. Clinical evidence shows that human blood pressure fluctuates significantly throughout the day and, therefore, frequent or continuous BP measurements provide a more complete and accurate view of cardiovascular health. However, arterial catheters – the current gold standard in continuous blood pressure measurement accuracy – are invasive, painful, difficult to set-up and present serious complication and infection risks. As such, they are usually reserved for the intensive care unit and surgical anaesthesia.

Advantages of Caretaker

Caretaker 4 enables wireless continuous non-invasive blood pressure (CNIBP) of each heartbeat and measures a range of other physiological parameters recorded in real time through a single finger cuff, without the need for cumbersome wires, electrodes and leads. The data is stored electronically and can be shared via any Bluetooth connected device. Backed by evidence from numerous clinical trials and US Food and Drug Administration (FDA) clearance, Caretaker 4 provides significant cost savings and efficiency gains. Simple to set up and use, Caretaker 4 can monitor patients in their home, in hospital or during ambulatory transport. Using Bluetooth wireless transmission, data collection is automated, streamlining clinician spot checks, remote monitoring and eliminating data entry errors and multi-machine setup. The Caretaker software interface allows patient data to be easily displayed on OEM monitoring equipment, linking psychological data with Early Warning Score (EWS) alarms.

How it works

The Caretaker 4 derives CNIBP, heart rate, respiration and other parameters utilising a patented method for Pulse Decomposition Analysis (PDA), incorporated into 
a rechargeable wrist-worn medical device with a single use finger cuff. A low power Bluetooth radio transmits data directly to the Caretaker Tablet App, OEM equipment, IT systems, monitoring platforms or electronic medical record (EMR) databases, allowing doctors and nurses to monitor and review its measurements in real time and review historical patient data. PDA is an algorithm and signal processing technique that processes the pulse-pressure waveform from the finger cuff to derive vital signs. PDA is based on the fact that the pulse is not a single disturbance, but exhibits structure from two internal reflection sites located in the central aortic tree. Caretaker detects the pulse and internal reflections of the systolic pulse through the patent pending low-pressure finger cuff, which is pneumatically connected to the wrist-worn electronic device. This device senses time varying pressure in the digital arteries, digitizes the pulse waveform, analyses the waveform using a patented PDA algorithm and displays the information on a remote display via Bluetooth. These algorithms produce continuous, non-invasive readings of blood pressure, heart rate and respiration. The patented PDA method comprehensively links the components of the peripheral pressure pulse envelope with the two central artery reflection sites. The first reflection site is the juncture between thoracic and abdominal aorta, which is marked by a significant decrease in diameter and a change in elasticity. The second reflection site originates in the common iliac arteries and provides a second reflected arterial pressure pulse, which counter-propagates to the direction of 
the primary systolic arterial pressure pulse due to left ventricular contraction. Quantification of physiological parameters is accomplished by measurement of the delay times and amplitudes of the reflected pulses. In the case of the continuous tracking of blood pressure, the PDA model’s predictions and previous experimental studies have shown that these two pulse parameters are of particular importance.

Caretaker Benefits in Hospitals 


US emergency rooms attend to 130 million patients annually. The ability to monitor patients as they await treatment will have a huge impact on patient outcomes, safety and hospital liability. With wireless vital signs monitoring technology, doctors are able to prioritize patients based on accurate, automated, real time data. Caretaker provides continuous and uninterrupted wireless monitoring as patients move through the full continuum of care: from the emergency department, to Diagnostics, Surgery, Recovery, and the General Ward. Caretaker’s CNIBP capability addresses a particular need in high acuity settings, such as the OR, ICU, and step-down units, where patients are high-risk or are unstable hemodynamically. In these settings, clinicians have few options for continuous vital signs monitoring. Data from Caretaker is wirelessly streamed to OEM displays, nurse station monitors and bedside terminals and logged into patient data files via the hospital EMR system.

Improved outpatient monitoring 

Caretaker provides a simple and comprehensive method for collecting vital signs data in a complete package, streamlining workflow and eliminating the need for disparate manual measurements and the risk of data transcription errors. This is especially useful in outpatient facilities such as surgery centers, general practitioners , oral/periodontal surgery centers, ENT centers infusion/dialysis clinics and urgent care centers. Caretaker’s quick and simple CNIBP capabilities provide indications of patient deterioration early, alerting doctors to take life-saving interventions or escalate to more comprehensive care. Skilled nursing facilities benefit from Caretaker’s simple form factor and connectivity, which allow patients full mobility throughout the facility, without being tethered to traditional monitoring equipment with bulky wires, cuffs and hoses. 

More reliable remote monitoring 

Caretaker’s ability to transmit data from anywhere for clinical review provides a compelling method of assessing and monitor patient health data to anywhere in the world.By linking Caretaker’s data to Telemedicine Video Carts, doctors can get patient vital sign data and real-time waveforms that are normally only available with much more expensive equipment solutions. The simplicity of use of Caretaker’s comfortable finger cuff increases the likelihood of patient compliance and enables multiple vital signs to be measured for remote review by clinicians. Streaming continuous data provides better information for diagnosis than the traditional spot-check measurements and comparison with historical data flags up changes in a patient’s health condition. 

Improving care while saving time and money 

Caretaker is FDA cleared for CNIBP, heart rate, SPO2 and respiration rate and in future will also measure other hemodynamic measurements such as internal bleeding detection, blood volume status and arterial stiffness. Additionally, the platform can gather and report health data from other Bluetooth enabled devices, such as glucometers, weight scales, fall and gait detectors, smart pill boxes etc, providing a complete picture of a patient’s physiological status. And with additional development its capabilities will extend to measuring cardiac output and LVET, as well as detecting arrhythmias and PVCs. Through the use of patented algorithms and technologies, Caretaker creates a true disruption to the established medical device monitoring market, enabling low-cost, comfortable, continuous vital signs monitoring at the point of trauma. As well as greatly improving the accessibility and accuracy of inpatient monitoring, this can help to support accountable care organizations in reducing the cost and time associated with hospital re-admissions, which is an increasingly important measure of the quality of care for many health systems.
