Tarilian Laser Technologies, a Hertfordshire, UK firm claims it has developed the “greatest technological advance in blood pressure measurement for 130 years” Unlike direct pressure measurement that every other BP meter does, the company’s Sapphire device uses an optical sensor to continuously measure blood pressure at the wrist. Keeping the Sapphire stationary will provide beat-to-beat readings and Tarilian says the device can effectively be used to detect white coat hypertension (raised blood pressure due to patient being in a clinical setting).
The company believes this technology can be translated for non-contact measurement of intraocular pressure, fetal heart monitoring, and for blood pressure monitoring using small mobile devices at different spots on the body.
Here’s a quick demo of the technology:
Features of TLT Sapphire from the product page:
- A cuffless device that delivers a high fidelity signal from which accurate and powerful haemodynamic biometric readings can be made
- An sensor that delivers results within nanoseconds – The TLT device delivers a continuous blood pressure within nanoseconds of being applied to the body
- No energy enters the body and there is no need for calibration
- Can be applied anywhere on the body; the neck, the eye, arms and legs etc ( we have even successfully developed an eye blood pressure monitor for example!)
- A continuous monitor that generates a unique waveform
- Beat-to-beat BP monitoring: generates a blood pressure every heart beat
- Carotid artery beat-to-beat BP monitoring
- Can even measure blood pressure directly in the eye
- Averaged BP monitoring (so the user can see a single SBP and DBP which can be updated every 5 heart beats)
- blood flow monitoring
- and also heart monitoring irregularities of the ventricles: can detect ventricular heart beat irregularities
