Walidacja systemu Dozee do bezdotykowego monitorowania pracy serca, oddychania i ruchu
Kliniczna walidacja systemu Dozee do bezdotykowego monitorowania tętna, częstości oddechów, ruchów i opuszczania łóżka
The Dozee VS system (K221555) is a contactless device that tracks heart rate and breathing rate using a sensor sheet placed under the mattress. It captures body vibrations and converts them into vital signs, which can be monitored remotely in real time. The system also supports add-ons like a blood pressure cuff, pulse oximeter, and thermometer, offering a complete monitoring solution. This study aims to validate the updated AI-powered heart rate and improved breathing rate algorithms across different sensor sheet types to confirm clinical accuracy

Szczegółowy opis
The Dozee VS system (K221555), developed by Turtle Shell Technologies, is a non-invasive, contactless device that continuously monitors heart rate (HR) and breathing rate (RR). A thin sensor sheet placed under the mattress detects tiny body vibrations from the heart and lungs, which are processed by smart algorithms and displayed on a secure online dashboard for real-time monitoring.
Unlike traditional methods such as ECGs, nasal tubes, or thermistors-which are invasive, require skilled placement, and are uncomfortable for long-term use-Dozee is simple, comfortable, and doesn't rely on patient compliance like wearables do. The system can also connect to add-on devices, including a blood pressure cuff, pulse oximeter, and thermometer, giving a full picture of a patient's vital signs and helping spot early signs of deterioration.
Hardware upgrades now include dual-sensor sheets that improve accuracy across different mattresses and patient types. The new HR algorithm uses AI/ML for better accuracy, while the improved RR algorithm performs more reliably even with movement or weak signals.
Study Goal: This study aims to validate the updated algorithms (Gen 2) for HR and RR across the three sensor sheet types (DS, S1, and S1-I) to ensure they meet clinical accuracy standards and to benchmark against the previous versions of the algorithms

Badana populacja
The study will be conducted on atleast 60 subjects in the age group above 18 years regardless of gender. The patients/volunteers be informed about the study and a written informed consent form will be obtained from them. Dozee will be placed under the mattress of the patient's bed and the data will be collected through the device whenever a patient is on the bed.

Single Arm Study (Cohort)
Group/Cohort Description: All participants will be on standard telemetry monitoring for Heart Rate and Respiration Rate using the gold standard (Electrocardiography and Capnography respectively). In addition, a contactless monitoring devices will be placed on the patient bed to measure data. This device is Dozee VS (Investigational Device). Data from all devices will be measured simultaneously. |
All participants will be on standard telemetry monitoring for Heart Rate, Respiration Rate and movements using the gold standard (Electrocardiography and Capnography respectively). |
