Abstract

The invention discloses a sensing device for finger detection. An inflatable ring and a circular rubber wrapping sleeve are installed in a shell. The two ends of the inflatable ring are respectively connected with the opening of the shell and the circular rubber wrapping sleeve. A proximal knuckle is sleeved in the inflatable ring, and a far-end knuckle and a middle-end knuckle are sleeved in the circular rubber wrapping sleeve. The outer periphery of the circular rubber wrapping sleeve is supported on the shell inner wall through an elastic supporting net. An air port of the inflatable ring is connected with a gas pressure sensor fixed in the shell. An inflation inlet and a gas vent of the inflatable ring are connected with a pressure-regulating device through an air pipe. A first photoelectric sensor and a second photoelectric sensor are respectively installed on the opening of the side surface of the circular rubber wrapping sleeve corresponds to the far-end knuckle and the middle-end knuckle. The sensing device for the finger detection integrates various finger detection in one sensing device so as to be used conveniently, reduces the discomfort and pain of users due to the fact that the inflatable ring replaces the traditional finger cuff, and can tightly fit for the finger so as to improve the measuring precision on the premise that comfortableness is ensured.

Description

technical field [0001] The invention relates to a sensing device, in particular to a sensing device for finger detection. Background technique [0002] At present, the volume compensation method is mostly used in blood pressure detection with finger arteries as the detection object. The method utilizes a pressure adjustment device to adjust the pressure of the cuff placed over the finger. The pressure in the cuff begins to drop gradually from higher than the finger arterial pressure to lower than the finger arterial pressure. During this process, the pulse wave photoelectric sensor can detect the fluctuation of blood flow along with the change of cuff pressure, and then indirectly obtain the systolic pressure and diastolic pressure of the artery. In the process, the heart rate can also be obtained according to the blood flow fluctuation graph. [0003] Pulse oximetry is often used to detect blood oxygen saturation with finger arteries as the detection object. This method...
