Embodiment Construction

[0031] The password input verification method and system of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0032] refer to figure 1 as shown, figure 1 It is a flowchart of a dimming method of a blood oxygen saturation measuring instrument according to an embodiment, including the following steps:

[0033] S101, before measuring the blood oxygen saturation of the finger to be tested, use the preset debugging output light intensity to test the finger to be tested on the blood oxygen saturation measuring instrument, and obtain the debugging received light intensity;

[0034] In this step, before measuring the blood oxygen saturation of the finger to be tested, put the finger to be tested into the finger cot, preset the output light intensity for debugging, test the finger to be tested on the blood oxygen saturation measuring instrument, and obtain Debug the received light intensity; compared with the existing debug...

Abstract

The invention relates to a light adjusting method and system for an oxyhemoglobin saturation measuring instrument, the measuring instrument and a measuring method. The light adjusting method comprises the steps that before the oxyhemoglobin saturation of a finger to be tested is measured, the finger to be tested is tested on the oxyhemoglobin saturation measuring instrument with preset debugging output light intensity, and debugging receiving light intensity is acquired; the light transmission coefficient of the finger to be tested is calculated according to the debugging output light intensity and the debugging receiving light intensity; the test output light intensity of the oxyhemoglobin saturation measuring instrument is calculated according to target receiving light intensity tested during oxyhemoglobin saturation measurement and a light transmitting system; the oxyhemoglobin saturation measuring instrument is controlled to emit testing light at the test output light intensity. According to the scheme, the adjusting process does not need to be repeated, light adjusting time is short, efficiency is high, and the oxyhemoglobin saturation measuring efficiency can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of blood oxygen measurement, in particular to a dimming method and system of a blood oxygen saturation measuring instrument, a measuring instrument and a measuring method. Background technique [0002] In blood oxygen saturation measurement, in order to meet finger measurements with different transmittances, the luminous intensity of the light-emitting device must be adjusted so that the received light intensity of the photodetection device is within a reasonable range, so that accurate measurement of blood oxygen saturation can be achieved. Measurement. [0003] The traditional dimming technology uses a comparison between the currently received light intensity and the target light intensity, and adjusts the output light intensity with a fixed step size. After repeated adjustments, the dimming will stop when the received light intensity is close to the target light intensity. . Due to the need for repeated...
