6 results about "Blood parameters" patented technology

State of art techniques for measurement of blood viscosity, RBC concentration and the like are in vitro methods. Embodiments of the present disclosure provide a method and system for in vivo non-invasive measurement of blood parameters using Laser Enabled Swept Frequency Acoustic Interferometry (LE-SFAI) principle. A Continuous Wave Laser diode based Photo Acoustic (CWPA) signal in frequency domain generated from laser excitation incident on a biological tissue of a subject carrying blood vessel is acquired by the ultrasound sensor and converted to a windowed time domain CWPA signal limited to two peaks. The signal characteristics such as risetime, amplitude, and time difference between first peak and the second peak are obtained to derive blood viscosity, Red Blood Corpuscles (RBC) concentration, and blood vessel diameter.

The present invention relates to a blood test method based on electrochemical impedance spectroscopy that can calculate clinical indicators in real time without separate clinical test equipment for calculating clinical indicators by changing the initial values ​​of blood parameters to fit the actual impedance and virtual impedance of the blood, and calculating clinical indicators using the blood parameters with changed initial values.

A vascular probe insertion assembly may include a slotted cannula having a sharp tip configured for insertion into a patient's vascular anatomical structure, and a side wall extending proximal to the sharp tip, the side wall defining the slot. A vascular probe insertion assembly may also include a digital probe comprising a divisible sheath molded to surround at least a portion of the side wall, a sensor tip configured to generate sensor data indicating the movement of the vascular anatomical structure, and a shaft extending proximal to the sensor tip. A vascular probe insertion assembly may also include a data hub operably coupled to the digital probe. The data hub may be configured to receive sensor data and transmit the sensor data to a monitoring system.
