Indications for Use
The Carematix Wellness System is a physiological monitoring system. The system collects, accumulates and transmits patient vital signs and other physiological data from a patient who may be remote from the healthcare practitioner to the practitioner. It is intended for patient home use for the following and can record physiological information such as: Non-invasive blood pressure measurement; Pulse rate measurement; Blood glucose level using a Glucometer; Blood hemoglobin oxygen saturation (%SpO2) and pulse rate using a digital Pulse Oximeter; Prothrombin Time (PT) and International Normalized Ratio (INR) measurement using an in-home coagulation measurement system; Body temperature measurement using a digital thermometry device or system; Peak Expiratory Flow Rate (PEFR) and Forced Expiratory Volume (FEV) measurements using an electronic peak flow meter; Patient weight using a stand-on electronic scale. The results of these measurements are transmitted to a computer monitoring station in a clinical setting via common telephone lines from the patient's home setting.
Device Story
Carematix Wellness System (CWS) is a remote physiological monitoring system for home use. It consists of a central hub and various cleared sensor devices (blood pressure cuff, scale, glucose meter, pulse oximeter, coagulation monitor, thermometer, peak flow meter). Sensors connect to the hub via wireless RF protocol (915 MHz). The hub collects data and transmits it via telephone line (modem) to a central Internet server. Healthcare providers access data via web browser to track trends, graph results, annotate variances, and set alert criteria (e-mail/pager). System facilitates remote management of chronic conditions by allowing clinicians to monitor patient vital signs from a distance, potentially improving patient outcomes through timely intervention.
Clinical Evidence
Bench testing only. Evidence includes verification of product requirements, functional specifications, proper storage of physiological data, and secure transmission of data to healthcare practitioners. No clinical trials were conducted.
Technological Characteristics
System includes a hub and various sensors (blood pressure, weight, glucose, SpO2, PT/INR, temperature, PEFR/FEV). Connectivity: Wireless RF protocol (915 MHz) between sensors and hub; modem/telephone line between hub and server. Power: 120 VAC for hub, batteries for sensors. Software: Proprietary data collection and transmission software. Sterilization: Not applicable (sensors are off-the-shelf).
Indications for Use
Indicated for remote monitoring of patients by healthcare practitioners. Collects and transmits vital signs including blood pressure, pulse, blood glucose, SpO2, PT/INR, temperature, PEFR/FEV, and weight. Intended for home use by patients under physician order.
Regulatory Classification
Identification
A radiofrequency physiological signal transmitter and receiver is a device used to condition a physiological signal so that it can be transmitted via radiofrequency from one location to another, e.g., a central monitoring station. The received signal is reconditioned by the device into its original format so that it can be displayed.

## 8. Non-clinical Testing
Similar to the predicate device Viterion 100 (K030419) which further refers to Panasonic Telehomecare system (K004050), the Carematix Wellness System utilizes patient sensors that have already received 510(k) clearance. The testing to demonstrate substantial equivalence for this product similarly to the predicates relies on:
- . Testing to meet the product requirements and functional specifications
- Verification that the physiologic data received by the patient monitors are stored . properly; and
- . Verification that the data is transmitted to the healthcare practitioner in a manner that maintains the security and integrity of the data.
### 9. Conclusion
After analyzing bench, electrical safety, FCC, and user testing data, it is the conclusion of Carematix, Inc. that the Carematix Wellness System is as safe and effective as the predicate device, has few technological differences, and has no new indications for use, thus rendering it substantially equivalent to the predicate devices. The modification to the Carematix Wellness System approved under K031840 submitted for approval in this application does not alter the fundamental scientific technology of the sensor devices.
