A portable diagnostic device for cervical precancerous lesions is disclosed. The device includes an inherent fluorescence detection system for cervical cancer, a cervix acetic acid coloring detection and an image collection system. The inherent fluorescence detection system for cervical cancer has a light source and a switch, which consists of a excitation light source that generates fluorescence and a cold light source that generates white light, both the excitation light source and the cold light source are installed in the bowl-shaped reflector with specific focal length. The cervix acetic acid coloring detection system has an acetic acid pool, a spraying tube that connects with the acetic acid pool, a spraying tube moving device, and a spraying switch. The image collection system has a weak light CCD, which is installed in the center of the bowl-shaped reflector. The image collection system is connected to the external image processing system which process the images collected by the image collection system. Use the white light and excitation light to irradiate the cervix in turn and collect the reflected images from the cervix. Spray acetic acid on cervix and use the white light and excitation light to irradiate the cervix in turn after waiting for a period of time. Collect the reflected images from the cervix which has been sprayed the acetic acid.
