Solution for continuous
core temperature monitoring

Solution for continuous core temperature monitoring

The temperature variable is a key indicator of the patient’s febrile state. The continuous nature of the measurement is quite difficult to obtain and only a few restrictive devices (rectal, esophageal probes, etc.) allow continuous core temperature monitoring.

eCelsius Medical system, class IIa medical device, is a miniaturized ingestible capsule that transmits core body temperature data continuously.

This capsule communicates in real time with a dedicated monitor, eViewer Medical, at a sampling period of 30 seconds. This monitor allows data recording and an alert may be triggered if a threshold has been exceeded. The communication distance between the capsule and the monitor ranges is around 1m (depending on environment and patient).

The capsule also has its own memory. In the case of a communication disruption between the monitor and the capsule, an a posteriori automatic synchronization of the data is performed.

The capsule is removed on the natural way; the operational lifetime corresponds thus to the transit time (24-48h on average). The capsule is a single-use device delivered sterile and in a stand-by mode. An activation box allows you to associate the eCelsius Medical capsule with the eViewer Medical monitor. A single monitor can manage up to three capsules simultaneously for mid/long term uses.

A dedicated interface, PC and MAC compatible, retrieves data for archiving or clinical use.

Various medical applications: research & clinical

The eCelsius Medical system allows continuous core temperature monitoring to diagnose or control the patient’s febrile state.
Three main applications will be firstly covered: infectious diseases, oncology care and sleep disorders.

Infectious diseases

Temperature monitoring in infectiology is critically important ; fever is indeed a fundamental clinical sign facilitating the implementation of an early and appropriate therapy.

Continuous core temperature monitoring, without human intervention, make possible to reduce medical response times and improve diagnosis reliability, patient comfort and patient care.

Oncology care

Early detection of peak fever is critical for patients treated with chemotherapy and presenting a high risk of febrile illness (aplasia, febrile neutropenia, …). The possibility to continuously monitor the evolution of the temperature variable allows to early detect fever pic and thereby reduce the response time for medical staff.

The rapid initiation of antibiotic treatment in a context of severe immunosuppression limits the risk of serious infection (septic shock) which can lead to the death of the patient. This can probably shorten the length of the hospital stay. As soon as the temperature exceeds 38°C, we consider that it is the trigger to start a treatment

Sleep disorders

The core temperature is a key indicator of the biological rhythmicity of the patients. Continuous monitoring of this variable allows to characterize the circadian rhythm of the core temperature, which is an essential tool for sleep analysis and the diagnosis of sleep disorders.
