Abstract

The invention relates to a calibration device for an oxyhemoglobin saturation analog meter. The calibration device comprises a dual-wavelength LED (light emitting diode) light source, an optical detector, a main unit and a computer, wherein the dual-wavelength LED light source is opposite to the optical detector; the dual-wavelength LED light source and the optical detector are connected with the main unit; the main unit outputs driving signals to drive the dual-wavelength LED light source to emit red light and near infrared light; the optical detector detects that optical signals emitted to a surface of the optical detector are converted into voltage signals which are inputted to the main unit; the main unit is connected with the computer, and receives an R curve command outputted from the computer; an R value, an oxyhemoglobin saturation value and a pulse frequency value are calculated according to the received voltage signals; and moreover, the oxyhemoglobin saturation value and the pulse frequency value are inputted to the computer; and the computer analyzes and processes data of the oxyhemoglobin saturation value and data of the pulse frequency value, and a calibration report is generated. By using the calibration device, oxyhemoglobin saturation and pulse frequency indexes of various oxyhemoglobin saturation analog meters can be calibrated.

Description

technical field [0001] The invention relates to a calibration (traceability) device for a medical testing instrument, in particular to a calibration device for a blood oxygen saturation simulator. Background technique [0002] Blood oxygen saturation (SpO 2 ) refers to oxyhemoglobin (HbO) bound by oxygen in the blood 2 ) capacity as a percentage of the total hemoglobin (Hb) capacity that can be combined, that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of the respiratory cycle. Many clinical diseases will cause the lack of oxygen supply, which will directly affect the normal metabolism of cells, and even threaten human life in severe cases. Therefore, real-time monitoring of pulse blood oxygen concentration is very important in clinical rescue such as anesthesia, surgery, PACU and ICU. important. Pulse oximetry is usually widely used as an important part of patient multi-parameter monitors, and the device can monitor b...
