Energy-saving finger clamping type pulse oximeter

The utility model discloses an energy-saving finger clamping type pulse oximeter, which relates to the technical field of oximeters and comprises a finger pressing plate consisting of two rotating plates, a lower half panel and an upper half panel are respectively mounted on the sides, close to each other, of the two rotating plates, and a lower finger clamping groove and an upper finger clamping groove are respectively formed on the surfaces of the lower half panel and the upper half panel. A photosensitive diode is embedded in the lower finger clamping groove, an infrared emitting part is embedded in the upper finger clamping groove, and dust shielding mechanisms are arranged in one end of the lower half panel and one end of the upper half panel in a distributed mode. According to the pulse oximeter, the dust shielding device is arranged on the lower half panel, dust is effectively prevented from entering the upper photosensitive diode when the pulse oximeter is idle, and the accuracy of the pulse oximeter
