The first sensor 10 can be a light sensor. When the motor 9 starts to drive the driving shaft 5 to rotate and rewind the towel, the first sensor 10 receives the light. After receiving the next sensing cursor, a stop signal is provided to the motor 9; it should be noted that: when the blood collection pillow of this embodiment is in use, one end faces the nurse and the other end faces the patient. A second sensor 11 is set at the end of the blood collection pillow facing the nurse. The nurse can manually touch the second sensor 11 to start the motor 9 and drive the active shaft 5 to wind the length of the pad towel at the distance between the two cursors. A third sensor 12 is set on the patient side of the blood collection pillow. The position of the third sensor 12 is preferably set on the side of the shell 1 located on the pad 8 close to the patient. After the patient's blood collection operation is completed, the third sensor 12 receives a signal that the patient's hand has left, and drives the motor 9, driving the active shaft 5 to rotate and drive the pad towel to wind. A switching switch 13 is also set at the bottom of the blood collection pillow. Through the switching switch 13, the motor 9 can be controlled to choose to start the motor 9 according to the patient's hand leaving the third sensor 12, or to start the motor 9 by the nurse touching the second sensing switch.

[0027] Specifically, the pad 8 is arranged on the supporting platform 14 in the middle of the shell 1, and the four corners of the surface of the supporting platform 14 are provided with a clamping part 15, and a groove body 16 is provided at the bottom of the pad 8. The four corners of the groove body 16 are provided with a clamping groove 17 for the clamping part 15 to be clamped and fixed. A driving component for driving the clamping part 15 to disengage from the clamping groove 17 is provided on the pad 8. In this way, the pad 8 can be disassembled and assembled, which is convenient for subsequent cleaning of the pad 8. The pad 8 is made of ABS material, which is easy to clean. A soft layer, such as a sponge pad, rubber pad, latex pad, etc., can be provided on the surface of the pad 8 to enhance the comfort of the patient's hand placed on the pad 8.

[0028] Specifically, a slide groove 18 for the clamping part 15 to slide is provided on the support platform 14 of the shell 1, and a first baffle 19 is provided at the inner end of each group of slide grooves 18 of the support platform 14, and a first spring 20 is provided between the first baffle 19 and the clamping part 15. Limiting grooves 21 are provided on the inner walls on both sides of the slide groove 18, and limiting plates sliding with the limiting grooves 21 are provided on both sides of the bottom of the clamping part 15 to prevent the clamping part 15 from detaching from the slide groove 18 when sliding. The first baffle 19 and the first spring 20 can be in the clamping groove 17 of the buckle and the pad 8 when the pad 8 is pressed on the support platform 14, and the clamping groove 17 can be a buckle structure.

[0029] Specifically, a first inclined surface 22 is provided on the side where the left and right clamping parts 15 are away from each other, and a pressing groove 23 is provided on the side where the front and rear clamping parts 15 are away from each other. The pressing groove 23 runs through the top of the clamping part 15, and a second inclined surface 24 is provided on the end surface of the pressing groove 23 close to the baffle, wherein the second inclined surface 24 is horizontally inclined from outside to inside. The driving part includes a main board 25 and a pressing rod 26. The main board 25 is slidably arranged in the groove body 16 of the pad 8 and is symmetrically arranged front and back in the groove body 16. The pressing rod 26 is arranged on the end surface of one side where the two main boards 25 are close to each other, and the pressing rod 26 is symmetrically arranged on both sides of the main board 25. When the pad 8 is placed on the supporting platform 14, the clamping part 15 can be driven to slide by squeezing the clamping part 15 through the first inclined surface 22. When the clamping part 15 is opposite to the clamping groove 17, the clamping part 15 will automatically buckle into the clamping groove 17 under the action of the first spring 20.

[0030] Specifically, the pad 8 is symmetrically provided with a return component in the groove body 16, and the return component is symmetrically arranged on the side where the two main boards 25 are close to each other. The return component includes a second baffle 27 and a second spring 28. The second spring 28 is fixed between the second baffle 27 and the main board 25. The two main boards 25 are provided with a pressure block 29 at one end away from each other. The pressure block 29 penetrates the inner wall of the groove body 16 and forms a sliding connection with the pad 8. By pressing the pressure block 29, the pressure rod 26 can be driven to abut against the second inclined surface 24 to drive the clamping portion 15 to disengage from the clamping groove 17. After the pressure on the pressure block 29 is released, the second spring 28 can return to its initial state.

[0031] A specific application example of this embodiment is:

[0032] When the device is in use, the patient places his arm on the pad 8 to perform the blood collection operation. After the operation is completed, the patient's arm leaves the third sensor 12 above the blood collection pillow. The third sensor 12 receives the arm leaving signal and drives the motor 9 to start. The motor 9 starts by driving the active shaft 5 to rotate and wrap the pad. After the first sensor 10 senses the downward sensing cursor signal, a stop signal is sent to the motor 9, thereby completing the replacement of the pad.

[0033] If during the use of the blood collection pillow, the nurse only needs to touch the second induction switch to replace the pad, which can be done by switching the switch 13 at the bottom of the blood collection pillow.
