HS-F Optical Oximetry Simulator
The HSF optical oximetry simulator is the newest accessory of the HS30 multifunctional simulator. This small but powerful accessory adds optical simulation capability to the HS30 simulator, allowing simultaneous verification of the oximeter and its sensor
By connecting the HS-F Optical Oximetry Simulator to the HS30 Multifunctional Simulator, it automatically turns on and the HS30 recognizes that the HS-F Optical Simulator has been connected.
With the HS-F optical simulator properly connected to the HS30, it can operate in two modes, manual or automatic, and this parameter is selected through the HS30 multifunctional simulator settings menu.
The optical oximetry menu allows you to select the HS-F operating mode as well as its operating parameters when configured for manual mode operation.
Teoria de Funcionamento:
As with electrical simulation, optical simulation synchronizes with the ECG signal and allows for variation of signal saturation, frequency and amplitude (perfusion). Pulse oximetry (SpO2) determines the value of oxygen saturation and peripheral pulse frequency using spectrophotometry and plethysmography techniques.
Oximetry sensors have two light emitters with different wavelengths at the top, one red and one infrared. At the bottom, it has a photodetector capable of measuring the amount of light of each type that passes through the finger.
When crossing the finger, these light emissions change depending on various conditions: tissue thickness, venous blood, arterial blood, bone, cartilage, skin color, etc. Oxyhemoglobin and deoxyhemoglobin absorb red radiation differently from infrared radiation. The relationship between the absorptions for 2 wavelengths used in the pulsatile part (arterial blood) determines the value of oxygen saturation.
The HS-F works as an optical simulator by reading the signal from the oximetry sensor emitters and modulating the brightness so that the connected sensor photodetector reads the oximetry.
A Brazilian company focused on the development of technological solutions for the medical segment, dedicated to designing, manufacturing and selling patient monitoring equipment and instrumentation for testing.
