[0027] Working principle: The patient places his arm in the hand pad slot 2 and places it on the toilet paper 3 for blood collection. After the blood collection is completed, the arm can be removed. When the toilet paper 3 needs to be replaced, press the switch 7 to start the motor 11. The motor 11 drives the paper roll on one side to rotate through the rotating shaft 15. During the rotation, the paper roll reels the toilet paper 3 that needs to be replaced, and at the same time drives the paper roll on the other side to move the clean toilet paper 3 out and place it in the hand pad slot 2. After the clean toilet paper 3 is used up, the fixing bolt 4 is rotated to remove the cover 9. The spring 12 and the push plate 13 give the paper roll a thrust to push it outward a distance, and then the paper roll is removed. After taking out the new paper roll, fix its end on the other used paper roll, and then put the two paper rolls into the installation slot 10. The toilet paper 3 passes through the paper slot 8 and then pushes inward. The cover 9 covers the notch of the installation slot 10. Reinstall the fixing bolt 4 to complete the replacement.
