Title:
BLOOD ION CONCENTRATION MONITORING APPARATUS AND METHOD AND CALCIUM ION CONCENTRATION MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/024665
Kind Code:
A1
Abstract:
A blood ion concentration monitoring apparatus and method and a calcium ion concentration monitoring method, relating to the field of blood purification. A monochromatic light source (2) emits monochromatic light, which is divided into first monochromatic light and second monochromatic light; the first monochromatic light sequentially passes through a blood pipeline (14) and a first monochromator filter group (4) and then is transmitted to a first optical signal converter (5); the second monochromatic light is transmitted to a second optical signal converter (7) through a second monochromator filter group (6); the first optical signal converter (5) and the second optical signal converter (7) are used for converting a light intensity signal into an electrical signal; and a controller (8) calculates a blood ion concentration according to a Beer-Lambert law. The blood ion concentration monitoring apparatus and method and the calcium ion concentration monitoring method can monitor an ion concentration in blood online, do not need to manually draw the blood, monitor the concentration of an electrolyte in the blood by using a blood gas analysis method, are convenient and labor-saving, perform ion concentration monitoring by using an optical principle, do not make direct contact with the blood, can prevent the blood from being polluted, and are high in precision.
