The electric push rod 14 is started, and the electric push rod 14 pushes the pressing plate 15 down. The pressing plate 15 then cooperates with the palm groove 28 on the constant temperature chamber 2 to fix the patient's palm. The detection element 16 in the palm groove 28 then detects the patient's various body data and then calculates the patient's blood sugar level. The rear cover 5 is rotated to open and the bolts 9 are rotated to remove the first slide 6, the second slide 7 and the third slide 8.
