Under the action of the reset spring 383, the positioning block 381 slides to the sliding hole 3 79, the positioning block 381 is separated from the positioning hole 382, ​​and the extrusion block 32 can be pulled at this time to make the connecting column 372 slide to the outside of the mounting hole 371, so as to facilitate the replacement of the clean extrusion block 32 and clean the extrusion block 32 stained with blood for reuse. The extrusion block 32 is detachably connected to the connecting rod 34 through a connecting mechanism, and the connecting column 372 has a simple structure and can reduce the cost of the connecting mechanism. Compared with the threaded connection that requires multiple turns to dismantle, the extrusion block 32 of the connecting mechanism only needs to be rotated slightly to complete the quick disassembly and assembly, thereby improving the replacement efficiency of the extrusion block 32, facilitating the quick replacement of the extrusion block 32 stained with blood, improving the cleanliness of the extrusion block 32, ensuring the use effect, and avoiding infection of the bleeding site of the patient.

[0048] A distance sensor is arranged at the center of the bottom surface of the force applying block 452, and the distance sensor is used to detect the distance from the center of the bottom surface of the force applying block 452 to the massage target position. A controller, a speed sensor and a power detector are arranged on the fixing plate 42, and the speed sensor is used to detect the speed of the motor 431, and the power detector is used to detect the real-time power of the motor 431. The controller is electrically connected to the distance sensor, the speed sensor, the power detector and the electric lifting rod 442 respectively. The controller controls the electric lifting rod 442 to extend based on the detection values ​​of the distance sensor, the speed sensor and the power detector, and includes the following steps:

[0049] Step 1: Based on the detection value of the distance sensor, the controller controls the electric lifting rod 442 to extend to a first target length. The first target length is calculated by formula (1):

[0050] H1=L1+L2 (1)

[0051] Wherein, H1 is the first target length, L1 is the detection value of the distance sensor, and L2 is the diameter of the massage ball 454;

[0052] Step 2: The controller controls the motor 431 to start, and controls the electric lifting rod 442 to extend to a second target length based on the detection values ​​of the speed sensor and the power detector. The second target length is calculated by formula (2):

[0053]

[0054] Among them, H2 is the second target length, θ1 is the Poisson's ratio of the material at the target position in contact with the massage ball 454, E1 is the elastic modulus of the material at the target position in contact with the massage ball 454, F1 is the preset massage strength, P1 is the detection value of the power detector, π is pi, π is 3.14, H1 is the first target length, and n is the detection value of the speed sensor.

[0055] The above scheme can massage the user's shoulders and neck according to the massage intensity required by the user, wherein the massage intensity required by the user is a preset massage intensity. When the user massages, the controller first controls the electric lifting rod 442 to extend to a first target length. At this time, the massage ball 454 contacts the target position, which is the clothes at the massage position of the user's shoulders and neck. Then the motor 431 is started, and the motor 431 drives the massage ball 454 to roll along the user's shoulders and neck. Since the massage ball 454 contacts the clothes at the massage position of the user's shoulders and neck, the massage intensity of the massage ball 454 is less than the preset massage intensity, which cannot satisfy the user. At this time, based on the detection values ​​of the speed sensor and the power detector, the second target length is accurately calculated by the above formula (2). Then the controller controls the electric lifting rod 442 to extend to the second target length. At this time, the massage intensity of the massage ball 454 on the user's shoulders and neck reaches the preset massage intensity, which can improve the user's comfort and satisfaction and avoid the situation where the user suffers from shoulder and neck discomfort due to long-term use of the neck brace.

[0056] Working principle: When using the neck artery pressure hemostasis collar of the present invention, according to Figure 1-Figure 8 , put the neck support body 1 on the user's neck, then clamp the block 10 in the fixing hole 9, fix the neck support body 1 on the user's neck, and adhere the Velcro fur surface on the fixing belt 6 to the Velcro thorn surface 8. When the position of the pressure component 3 needs to be adjusted, press the fixing column 311 so that the fixing column 311 reaches the fixing groove 332. At this time, the outer clamping tooth 314 leaves the inner clamping tooth 334, and then rotate the outer fixing tube 313 to rotate the limit block 312 to the bottom of the limit groove 333, fix the outer fixing tube 313 on the mounting block 331, and then rotate the pressure component 3 to make the inner clamping tooth 334 move along the clamping groove 2. After moving to the required position, rotate the outer fixing tube 313 to make the limit block 312 leave the bottom of the limit groove 333, and then The outer engaging teeth 314 are pulled back to the inner engaging teeth 334 so that the outer engaging teeth 314 are embedded in the pores of the inner engaging teeth 334, so that the inner engaging teeth 334 cannot move in the slot 2, and the pressurizing component 3 is fixed on the neck support body 1. When the user uses the neck support for a long time and causes shoulder and neck discomfort, the motor 431 is started to rotate the driving shaft 434, driving the first driving gear 432 and the second driving gear 433 to rotate. The rotation of the first driving gear 432 drives the first driven gear 436 to rotate and then drives the driven shaft 438 and the second driven gear 437 to rotate. The rotation of the second driving gear 433 and the second driven gear 437 drives the third driven gear 435 to move up and down, thereby causing the massage head 45 to move up and down to massage the user's shoulder and neck.

[0057] In summary, the present invention provides a neck artery pressurized hemostatic collar, which moves the pressurizing component 3 to the bleeding position so that the squeezing block 32 squeezes the middle hemostatic cotton 7, and squeezes the middle hemostatic cotton 7 to the bleeding position. The squeezing block 32 applies pressure under the action of the spring 36, which not only enables the middle hemostatic cotton 7 to be close to the bleeding position, but also compresses the bleeding position to achieve compression hemostasis, avoids postoperative incision compression treatment pressure is too small, may occur bleeding, carotid artery pseudoaneurysm, secondary surgery and other postoperative complications, improves the effect of nursing, the second driving gear 433 and the second driven gear 437 are The second driving gear 433 and the second driven gear 437 have opposite movement directions. The second driving gear 433 drives the third driven gear 435 to rotate clockwise, and the second driven gear 437 drives the third driven gear 435 to rotate counterclockwise. Therefore, the rotating shaft 430 rotates 180° clockwise and then immediately rotates 180° counterclockwise, so that the massage head 45 reciprocates up and down, achieving the purpose of tapping the user's shoulder and neck, so that the massage head 45 can massage the user's shoulder and neck, avoiding the situation where the user suffers from shoulder and neck discomfort due to long-term use of the neck support.
