The present invention provides a multi-section finger sleeve-type probe, which comprises a finger sleeve body, a flexible flat cable mounted on the finger sleeve body, a light emitting diode, a photo diode, and a wire electrically connected to the flexible flat cable. The finger sleeve body is a cylinder with an opening at the bottom thereof. Comparing with an existing finger sleeve-type probe in which wiring pipes are provided on both the left and right sides of a silicone sleeve and thus the silicone sleeve is flattened, the finger sleeve body fits the shape of a finger and fully wraps around the finger. While being used, the finger is inserted into the finger sleeve body and expands the periphery thereof, thus the finger is totally wrapped to provide a big resistance. The multi-section finger sleeve-type probe can be worn stably, be not easy to drop off, and be suitable for long term use. Also, the finger sleeve body from top to bottom comprises a first knuckle sleeve and a second knuckle sleeve respectively corresponding to the distal knuckle and the medial knuckle of the finger, thus allowing the two knuckles of the finger to be fixed, thereby further increasing the stability of the finger sleeve-type probe when worn.
