Finger root type blood oxygen probe

Abstract

The invention relates to a finger root type blood oxygen probe which is composed of a casing body, a presser foot, an elastic pad, a signal line and sensors. The section of the casing body is in a groove shape, and the elastic pad is arranged in the casing body. The sensors are symmetrically arranged on the two faces of the inner side of the casing body. The presser foot is fixedly connected withthe lower portion of the casing body. The signal line is arranged on the casing body, and the sensors are electrically connected with the signal line. The oxyhemoglobin saturation probe detects oxyhemoglobin saturation at the finger root. The movement range of the finger root is smaller than the movement range of the fingertip, and the presser foot is arranged to prevent the probe from moving andfalling off, so that the probe can be more stably arranged at the finger root, and the accuracy of measured data is ensured. Meanwhile, the signal line, the finger root and the wrist extend in the same direction and can be attached to the back of the hand, so that the suspension length of the signal line is reduced. The traction effect of the signal line on the oxyhemoglobin saturation probe is small when the hand moves, and measurement is stable. The twisting traction opportunity of the signal line is small, so that and the service life of the signal line is prolonged. The probe and a light shield form a square closed space, so that interference light entering the probe is reduced, and the accuracy of detection data is improved.

Description

technical field [0001] The invention relates to a blood oxygen probe, in particular to a finger root blood oxygen probe. Background technique [0002] At present, blood oxygen saturation probes in the prior art mostly use clip-type fingertip blood oxygen saturation detection, that is, the blood oxygen saturation probe is clamped at the fingertip of the finger to detect blood oxygen saturation. If the probe is large, it will cause the probe to loosen and fall off, which will make the detection data inaccurate or impossible to detect; the signal line of the blood oxygen saturation probe is at the tail of the blood oxygen saturation probe at the far end of the fingertip, and the signal line is long and has a certain When the hardness is moved by the finger, the signal line will increase the torque of the blood oxygen saturation probe, causing the probe to fall off easily and the signal line to break easily; in addition, in the prior art, trapezoidal gaps are formed on both side...
