Brief summary
1. Aim: The aim of the clinical trial is to study the accuracy of the TensorTip device compared with registered (FDA-approved) invasive and non-invasive devices. 2. Hypothesis: Human physiological biomarkers may be measured from the color distribution of the internal or external (skin) tissue. The technology of the TensorTip finger-mounted device is based on the color distribution of the peripheral blood tissue, which enables the measurement of certain biomarkers and vital signs under consideration.
Detailed description
The TensorTip (previously named Soft Touch) is a novel non invasive Finger tip device that. The Tensor Tip is a non-invasive device which was designed and aimed to measure a wide range of physiological and bio-parameters such as blood glucose, hemoglobin and hematocrit, blood PH, oxygen saturation SpO2, blood carbon dioxide, blood pressure, peripheral pulse and more based on the temporarily color distribution of the tissue under consideration. The Tensor Tip is based on real time color image sensor, real time photographing the fingertip tissue. A color image sensor of the type used in the Tensor Tip enables a wide range of information in the spectral, resolution, dynamic range and time domains enabling further investigation of the blood chromatic changes as a function body physiology. The concept behind this investigation reflects the idea that a change in human physiology condition would temporarily change the blood pigmentation. The present study is aimed to assess the accuracy of the novel device in measuring all the above mentioned parameters by recording AS IS the change of the fingertip color tissue while simultaneous recording the standard invasive measured parameters on daily or periodic routine in the hospitalized patients. This vast data recordings (tissue and references) enable the Tensor tip to analyze a particular bio parameter. The tensor tip is calibrated to a certain bio parameter based on the vast data set collected. The bio parameter under consideration are: Arterial Systolic and Diastolic, MAP, PA systolic, PA Diastolic, CO, Heart rate, Stroke volume, WBC, RBC, Hgb, HCT ,Iron, PLT, PH, PCO2, PO2, HCO3, SaO2 , Na, K, Cl, CO2, Bun, Cr, Gluc, HGB (A1C),TBiLi, LDL, HDL. This study hopes to demonstrate the connection between blood color pigmentation and certain bio parameters for simplifying monitoring procedure and particular home monitoring.
