One side of the interior of each of the transfer arms (16) is threadedly connected with a second screw rod (14).

10. A monitoring method for a nursing oxygen saturation monitor according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: According to the actual needs of the patient, the personnel pinches the knob (32) and rotates each pressure ring (15) and the second screw (14) counterclockwise to loosen the second screw (14), thereby loosening the force of the outer wall of the slider (13) squeezing the inner wall of the slide arm (12), thereby contacting the restriction on the position of the slide arm (12), and then slides each slide arm (12) to the desired horizontal position on the inner side of the transfer arm (16), rotates the second screw (14) clockwise, and tightens the slider (13) in conjunction with the pressure ring (15) to increase the pressure of the outer wall of the slider (13) squeezing the inner wall of the slide arm (12), fix the position of the slide arms (12) on both sides, rotates the third screws (22) on both sides of the bracket (18) counterclockwise to loosen them, cooperates with the U-shaped limiting hole (23), slides the slide (24) to the desired position, and rotates each third screw (22) clockwise to fix the position of each elastic binding belt (25) on the top of the slide (24); Step 2: The personnel places the upper arm flat on the top of the support pad (21), and then completes the binding of the upper arm by bonding the Velcro (26) and Velcro (27) between the adjacent Velcro patches on the top of the elastic binding belt (25). Then, the patient's forearm is placed flat on the top of the buffer pad (30), and the tail ends of the lower clamp (1) and the upper clamp (5) are pinched. The grooves on one side of the lower clamp (1) and the upper clamp (5) and the upper base plate (4) are rotated on the inner side of the rotating shaft (3) to open one end of the lower clamp (1) and the upper clamp (5). The patient's fingers are placed between the lower clamp (1) and the upper clamp (5), and then the lower clamp (1) and the upper clamp (5) are released. After the rebound member (10) is reset, The lower clamping piece (1) and the upper clamping piece (5) are used to clamp the finger, and the transmitter (8) is turned on to irradiate the finger part. The transmitter (8) feeds back the irradiation result to the sensor (7). The sensor (7) processes the information and sends the final data to the display mechanism (6) for display. Finally, the elastic binding belt (25) is released from binding the limb. This can effectively reduce the possibility that the device will fall off when the user's limb shakes due to illness or physical abnormality after being connected to the user's finger in a clamping manner, and medical staff need to manually limit the amplitude of the patient's limb. While effectively ensuring the measurement efficiency, it also reduces the physical exertion of medical staff.
