Toumaz Limited (AIM: TMZ, ‘Toumaz’, or ‘the Group’), a UK-based pioneer in low cost, ultra-low power wireless technology, has started the pilot of its digital vital signs monitor, at St. John’s Health Center, Santa Monica, California; a major US hospital.

The monitor is a disposable, ultra-thin plaster which continuously monitors the patient’s heart rate, respiratory rate and temperature whilst in hospital. The monitor significantly increased patient surveillance compared to current practice, which involves manual measurement of vital signs every six to eight hours.

is intended for use in general hospital wards which account for the vast majority of hospital beds, as opposed to traditional monitoring devices which can be bulky, wired products and may be restricted to intensive care units. The device, which also has an alert capability, enables patients to be fully mobile whilst being monitored.

Any deterioration in condition can be detected by the monitorand dealt with immediately, thereby reducing the number of patients admitted or readmitted to intensive care and the overall hospital spend.

In the US alone, wireless vital signs monitoring devices are forecast to reduce healthcare costs by around $200 billion over the next 25 years (Center for Technology and Aging Report, May 2010).

The pilot is being carried out at St. John’s Health Centre in Santa Monica, California, by Toumaz US, the Group’s US joint venture with Dr Patrick Soon-Shiong’s company NantWorks.

CTO of NantHealth, a NantWorks company, commented:

The digital plaster is a fully disposable device, with smart sensor interface and transceiver, aimed at the general wards of hospitals. The device continuously monitors patients’ vital signs (heart-rate, respiration rate & temperature) and wirelessly communicates this data to doctors and nurses via the hospital’s IT system.

Currently, the majority of patients in hospital have measurements of vital signs taken manually at six to eight hour intervals. This relatively infrequent monitoring means that deterioration in patient conditions may go unnoticed, leading to further treatment or re-admittance to intensive care units.

The monitor is a disposable ultra-thin plaster that is attached to patients under their clothing. The device enables the patient to be completely ambulatory and still be monitored.

Hospital staff can set up alerts that can be sent to pagers/handheld devices to warn them of patient deterioration. This enables caregivers to prioritise patients based on their condition. has a battery life of five days, covering the average length of a general ward stay in the hospital. At the end of a patient’s stay the entire device can be disposed of.

Key benefits include:
