BPro A-PulseTM (Healthstat) noninvasive tonometric device

BPro® Radial Pulse Wave Acquisition Device

BPro® is a revolutionary device that provides the medical practitioners and researchers alike with unprecedented capabilities in acquiring highly reproducible & accurate real time arterial pulse wave data and 24-hr Ambulatory Blood Pressure Monitoring [ABPM]. These breakthroughs are achieved both by innovative hardware design and software algorithm of patented EVBP® technology.

BPro® with its ease of use and integrated application software packages have the potential to make real time 24-hr ABPM and arterial pulse waves measurement the standard of medical care for the early health management of hypertension and related illnesses.

BPro® Device Capabilities with Integrated Application Software Package:

(I) A 24-hr macroscopic view of BP patterns, including blood pressure, heart rate, mean arterial pressure and pulse pressure.

BPro® is the first device in the world that uses applanation tonometry methodology to capture 24-hr blood pressure readings. It takes the blood pressure measurement even without the wearer knowing about it.

(II) Real time microscopic arterial pulse waveform analysis.

Using the BPro® and the pulse wave analysis application software, one is able to acquire real time arterial pulse wave data and translated this waveforms into clinically diagnostic related indices. Every clinician now has a very powerful tool for complete assessment of the status of the arterial tree of patients, including evidence-based approaches in the treatment and management of pulse wave related illnesses.

BPro® validated by AAMI and ESH
BPro® has been validated independently by the National Heart Centre of Singapore in compliance with the protocols set by the Association for the Advancement of Medical Instrumentation (AAMI) and European Society of Hypertension (ESH).

BPro® EVBP® Technology  
BPro® incorporated a patented technology termed as Modified Applanation Tonometry. This technology is coined as EVBP® technology. EVBP® stands for Evidence-Based Blood Pressure. Tonometry was first used for the measurement of pressure in the eyeballs. HealthSTATS BPro® ABPM device implements the measurement at the radial artery of the wrist. (see illustration below).

The figure shows the cross section of the wrist that the BPro® is secured to the wrist by means of a wrist strap, similar to a watch in application.

The sensor plunger impinges upon the radial artery over the radius bone. The patented plunger system design is hemispherical in profile, and transfers pressure forces efficiently to the internal pressure sensor and provides a safe, comfortable patient interface.

The wrist strap system is specially designed to ensure that the sensor system mounted comfortably on the radial artery position. At the same time, together with the sensor housing, it provides constant applanation to the artery without compromising the comfort of the wearer. The strap system also takes into consideration in allowing for venous return at both the watch head and housing, and also avoiding any median nerve compression.
With the above features, a non-invasive reliable and accurate radial pulse wave is acquired.

BPro® Device Description

BPro® device is a non-invasive pulse wave acquisition using modified applanation tonometry to acquire reliable and accurate real time arterial radial pulse waves. By using the captured data, BPro® with its ease of use and integrated application software packages has the potential to make real time 24-hour ABPM and arterial pulse wave measurement the standard of medical care for the early health management of hypertension and related illnesses.

As shown in figure above, BPro® is a watch-like device worn on the patient's wrist. It is easy to use and mount on the wearer's radial artery.

BPro® Feature
                            Specially designed to visually reflect a watch-like monitoring device.
                  Lightweight and easy to use.
                  Specially designed mounting strap to secure BPro® device onto the wrist position.
                   Does not disturb daily activities and night sleep.
                   Delicate sensor with high accurate data acquisition capability

               Able to monitor 24-hr blood pressure and capture real time arterial pulse waves.

ABPM refers to monitoring of your blood pressure [BP] over a period of 24 hours as you go about your normal daily activities. Your BP fluctuations over this period form the ABPM patterns. This allows your doctor to decide if the pattern is normal or if you needed to be treated. To date, nine main patterns have been identified. Every pattern carries different risks of heart attack or stroke. With the knowledge of your pattern, effective treatment can be targeted to achieve normal pattern, thus reducing the risk.

Generally, the first ABPM session is to establish your status. A repeat ABPM session after treatment is important to show the effectiveness of treatment.

Do you know your 24-hr BP pattern? We have four BPro® Centres in Singapore where you can have your 24-hr ABPM measured and learn more about hypertension and other related illnesses.
