Objective: Blood-leak detection is a key basic requirement in continuous renal replacement therapy(CRRT) equipment.Thus,the feasibility of the application of a new color sensor TCS230 in CRRT equipment for blood-leak detecting is investigated.Methods: Using a light-emitting diode(LED) as light source and a programmable color light-to-frequency con-veter TCS230 as color sensor designed a non-contact blood-leak detecting circuit and constructed a blood-leak detection exp erimental simulation platform.The HSL color space method was adopted to convert the RGB values to HSL values.Thereafter the detected color was determined in accordance with the changes of H hue values.Results: The experimental results show that the non-contact detection device is able to distinguish the blood leak status from the normal condition and blood-leak condition which are two simulation working models.Conclusions: From the experimental verification conclusions can be drawn that the color sensor TCS230 is feasibly applied to blood-leak detecting,and it can simplify the structure of detection device.Furthermore,the relative detection method is introduced,so the special light source of detection device is not required and thus the device cost will be reduced.
