Whenever a person suffers from any kind of infection, their body temperature usually fluctuates. Hence, it is important to keep a track of the changing temperature. BodyCap, a France-based company, earned a European CE Mark to establish its e-Celsius swallowable wireless thermometer. The device is developed to evaluate the core temperature of a patient. It looks similar to an ordinary drug capsule and also should be ingested like it.
The e-Celsius device belongs to the class IIb medical device that enables constant estimation of the central temperature of a patient by the gastrointestinal tract. The device is enclosed in a biocompatible medical grade plastic. When a patient swallows the electronic pill, it goes along the intestinal path. The internal temperature values are transmitted wirelessly by the pill to a monitor known as e-Viewer. Alert notification is given when the estimation is beyond the range specified by the healthcare professionals. The pill is excreted through the body naturally within 1–3 days.
The patient’s central temperature is one of the important variables that is regularly checked during therapeutic follow-up or diagnosis in hospitals. It can verify an infectious peak, observe the course of a fever, or avert the hypothermia risk. Constant supervising of the patient’s temperature is done during many instances:
- During major surgery that involves post-operative follow-up and extended general anesthesia;
- During ambulatory surgery for constant temperature monitoring;
- In general medicine for diagnostic uses;
- In infectiology or tropical medicine, for quicker management of pandemics;
- During the treatment of immunosuppressed patients or who are at a high risk of infectivity;
- During the follow-up of chemotherapy treatments so as to control its side-effects;
- During sleep disorder study.
The reliability and performance of the e-Celsius device have been evaluated in clinical trials. The studies illustrated the gastrointestinal tract’s heat homogeneity and the correspondence to results from the esophageal and/or rectal probes, which are the gold standard at present within the hospital settings. The tests also demonstrated that the device has a positive impact on the well-being of the patient as well as the medical personnel.
Thus, this device can be helpful to sensitive patients such as those who are at risk of infection owing to their compromised immune system.
