Dispositivo de evaluación rápida del estado cardiovascular


Oferta Tecnológica
Una universidad catalana ha desarrollado un sistema fácil de usar y asequible para determinar diferentes parámetros cardiovasculares en medidas sin supervisión fácilmente obtenidas de las manos y pies. Este sistema evita el uso de geles o cremas y el contacto con el tórax o cualquier otra parte del cuerpo que no sean las manos y los pies, ofreciendo información del corazón y de los vasos sanguíneos en muy poco tiempo. El sistema puede adaptarse a cualquier tecnología inalámbrica. La universidad busca compañías del sector de dispositivos médicos con el fin de establecer acuerdos de licencia y cooperación técnica para continuar con el desarrollo y lanzar la tecnología al mercado.


Fast cardiovascular condition assessment device.
A Catalan university has developed an easy-to-use and affordable system able to determine several cardiovascular parameters from unsupervised measurements easily obtained at hands or feet. The university is looking for medical devices companies for license and technical cooperation agreements to further develop the device and bring it to the market.
Cardiovascular diseases are the leading cause of death yet. Plenty of patients remain undiagnosed until acute stages of the disease. Population screenings with existing equipment are unaffordable hence there is a need for comfortable easy-to-use devices intended for personal periodic cardiovascular monitoring that do not interfere with daily routines and can be used anywhere.

The hands and the feet are very convenient interfaces for cardiovascular measurements and have long been used to obtain the heart rate and the electrocardiogram (ECG) by establishing a contact with a conductive electrode on each hand. Furthermore, volumetric changes that result from the arrival of the blood pulse to different arteries of the body can be detected from the changes in electrical impedance measured between both hands through the so-called impedance plethysmogram (IPG).

A Catalan university research group has designed a measurement system able to simultaneously obtain the ECG and the IPG by using only four conductive contacts, which can be for example two contacts with two different fingers of each hand, or two contacts with fingers in one hand and two contacts with two points on the opposite wrist. Time intervals between different features of the ECG and the IPG yield the Pulse Arrival Time (PAT), which can be used to assess autonomic nervous system activation and changes in blood pressure. It also provides the Pre-Ejection Period (PEP), which can be used to assess myocardial contractility, sympathetic activity or to diagnose certain cardiovascular diseases from abnormal durations. Furthermore, an extra sensor at the hands or the feet, such as a PPG system, an additional IPG measurement using the same electrodes, or a ballistocardiogram (BCG) obtained from a weighing scale, allows us to obtain the Pulse Transit Time (PTT) and evaluate arterial stiffness, which can be related to factors such as ageing, hypertension, and risk of cardiovascular events.

The applications and target markets are personal healthcare, m-health, e-health, remote physiological monitoring, drug testing, drug dose adjustment, home health care, health promotion programs, fitness, physical activity monitoring, sports medicine, fitness centers, labor medicine, groups screening, primary care centers, community health centers, hotels, and spas.

The university is looking for medical devices companies interested in monitoring and evaluation of cardiac and vascular parameters for license and technical cooperation agreements.

The technology is now in a laboratory prototype stage and the collaboration sought is to finish the prototype, validation and regulation, the industrial scale-up and the commercialization.
Advantages and Innovations:
- No gel or cream, nor contacts with the thorax or any body part other than the hands or the feet are required.
- No auxiliary personnel are required to apply it.
- Provides information about both the heart and the major blood vessels and in a short time.
- Can be adapted to any wireless technology.
Stage of Development:
Prototype available for demonstration
Patent(s) applied for but not yet granted
CommeR Statunts Regarding IPR Status:
