The bottom surface of the patient's ankle 113 contacts the surface of the foot support plate 101. The inner wall of the foot strap 102 contacts the surface of the patient's ankle 113. A limiting plate 114 for fixing the patient's foot is placed on the surface of the patient's ankle 113.

[0027] Furthermore, such as Figure 2 and Figure 5As shown, a universal adjustment mechanism 2 is provided on both the inner wall of the first strap 104 and the surface of the sub-adhesive 106. The universal adjustment mechanism 2 includes a guide groove 21, a guide block 22, and a universal adjustment assembly 23. The universal adjustment assembly 23 is disposed on the inner wall of the first strap 104 and the surface of the sub-adhesive 106. The universal adjustment assembly 23 is composed of an arc-shaped clip 231, an arc-shaped slot 232, and a telescopic spring 233. The inner wall of the first strap 104 is provided with a guide groove 21. The device is provided with equally spaced arc-shaped clips 231. Guide blocks 22 are installed on the surface of the sub-adhesive 106. The guide blocks 22 slide with the inner wall of the guide groove 21. The surface of the guide blocks 22 is provided with arc-shaped slots 232. The arc-shaped slots 232 slide with the inner wall of the guide blocks 22. The arc-shaped slots 232 and the inner wall of the arc-shaped clips 231 engage with each other. The surface of the arc-shaped slots 232 is provided with telescopic springs 233.

[0028] During implementation, the user pulls the sub-adhesive 106 on the surface of the first strap 104 according to the size of the patient's ankle 113. This causes the sub-adhesive 106 to slide the guide block 22 inside the guide groove 21. Under the combined action of the guide groove 21 and the guide block 22, the sub-adhesive 106 is guided. At this time, under the elastic force of the telescopic spring 233, the arc-shaped slot 232 moves, causing the arc-shaped slot 232 to automatically lock into the interior of the corresponding arc-shaped clip 231. Under the locking action of the arc-shaped slot 232 and the arc-shaped clip 231, the sub-adhesive 106 and the first strap 104 are fixed together, so that the size between the sub-adhesive 106 and the second strap 107 can be adjusted to achieve the function of fixing the patient's ankle 113 of different sizes with the protective strap.

[0029] Furthermore, such as Figure 2 and Figure 6 As shown, the inner wall of the medical adhesive tape 111 is provided with a waterproof and hypoallergenic mechanism 3. The interior of the waterproof and hypoallergenic mechanism 3 includes a first hypoallergenic adhesive layer 31, a second hypoallergenic adhesive layer 32, a waterproof layer 33, and an adhesive layer body 34. The waterproof layer 33 is adhered to the inner wall of the medical adhesive tape 111. The adhesive layer body 34 is adhered to the surface of the waterproof layer 33 away from the medical adhesive tape 111. The first hypoallergenic adhesive layer 31 for hypoallergenic protection of the patient's ankle 113 is adhered to the surface of the adhesive layer body 34 away from the waterproof layer 33. The second hypoallergenic adhesive layer 32 is covered on the surface of the first hypoallergenic adhesive layer 31 away from the adhesive layer body 34. The inner wall of the second hypoallergenic adhesive layer 32 is bonded to the surface of the first hypoallergenic adhesive layer 31 away from the adhesive layer body 34.

[0030] In practice, when a patient with allergies uses the protective band body 1, the patient's ankle 113 may experience allergic reactions due to prolonged contact with the surface of the medical tape 111. At this time, the waterproof layer 33 provides a high degree of waterproofing to the surface of the medical tape 111, and the adhesive layer body 34 makes the waterproof layer 33 and the first anti-allergy adhesive layer 31 adhere more firmly. The combined action of the first anti-allergy adhesive layer 31 and the second anti-allergy adhesive layer 32 can prevent allergies on the surface of the patient's ankle 113, thus improving the effectiveness of the protective band body 1 and achieving the function of fixing the protective band to prevent allergies on the surface of the patient's ankle 113.

[0031] Furthermore, such as Figure 3 and Figure 7 As shown, both the protective strap body 1 and the anti-slip strap 103 are provided with a high-efficiency fixing mechanism 4. The high-efficiency fixing mechanism 4 includes a connector 41, adhesive 42, and a high-efficiency fixing assembly 43. The high-efficiency fixing assembly 43 is provided on the surface of the protective strap body 1 and the anti-slip strap 103. The high-efficiency fixing assembly 43 consists of an anti-slip pin 431, an anti-slip groove 432, an elastic clip 433, and a Velcro body 434. The connector 41 is installed on the surface of one end of the anti-slip strap 103, and the Velcro body 434 is provided on the surface of the protective strap body 1. The surface of the Velcro body 434 rotates and engages with the surface of the protective tape body 1. Adhesive 42 is installed on the inner wall of the Velcro body 434. The surface of the adhesive 42 is bonded to the surface of the connector 41. Anti-detachment pins 431 are installed on the surface of the connector 41. Anti-detachment grooves 432 are opened on the inner wall of the Velcro body 434. The anti-detachment grooves 432 and the surfaces of the anti-detachment pins 431 engage with each other. Elastic clips 433 for preventing the Velcro body 434 from detaching are installed on the surface of the anti-detachment pins 431. The elastic clips 433 engage with the inner wall of the Velcro body 434.

[0032] During implementation, the user pulls the anti-slip strap 103 on the surface of the protective belt body 1, causing the first strap 104 to move the connector 41 to one side of the protective belt body 1. Then, the user pulls the Velcro body 434, causing it to move to the surface of the connector 41. Under the action of the adhesive 42, the Velcro body 434 is adhered to the surface of the connector 41. At this time, the anti-slip pin 431 is engaged inside the anti-slip slot 432. The engagement between the anti-slip pin 431 and the anti-slip slot 432 fixes the connector 41 and the Velcro body 434. At this time, the anti-slip pin 431 causes the elastic clip 433 to automatically engage with the inner wall of the Velcro body 434, preventing the connector 41 and the Velcro body 434 from loosening. This effectively fixes the protective belt body 1 to the patient's leg, achieving the function of efficient fixation of the protective belt.

[0033] Working principle: When using, the user first inserts the indwelling needle into the surface of the patient's ankle 113, and then attaches medical tape 111 to the surface of the indwelling needle. The medical tape 111 initially fixes the indwelling needle to the surface of the patient's ankle 113. Subsequently, the user places the limiting plate 114 on the surface of the patient's ankle 113. The limiting plate 114 restricts the user's ankle movement, preventing the indwelling needle from falling out due to ankle twisting.

[0034] Subsequently, the user places the protective strap body 1 on the surface of the patient's ankle 113, causing the patient's foot to move to the surface of the foot support plate 101. The foot support plate 101 provides support for the patient's foot. The user pulls the foot strap 102 on the surface of the foot support plate 101, causing the foot strap 102 to move the fixing plate 110. At this time, the fixing plate 110 moves the sub-hook and loop fastener 109 to contact the surface of the female hook and loop fastener 112. Under the combined action of the sub-hook and loop fastener 109 and the female hook and loop fastener 112, the patient's foot is secured. Fixed to the surface of the foot support plate 101, the protective strap body 1 and the foot support plate 101 work together to fix the patient's foot and leg. Then, the user pulls the sub-adhesive 106 on the surface of the first strap 104, causing the sub-adhesive 106 to move to one side of the protective strap body 1. Then, the user pulls the female adhesive 108 on the surface of the second strap 107, causing the female adhesive 108 to move above the sub-adhesive 106. Under the combined action of the sub-adhesive 106 and the female adhesive 108, the protective strap body 1 is fixed to the patient's leg.

[0035] Subsequently, due to the varying sizes of patients' ankles 113, the user needs to adjust the size between the sub-adhesive patch 106 and the second strap 107. Based on the size of the patient's ankle 113, the user pulls the sub-adhesive patch 106 on the surface of the first strap 104, causing the sub-adhesive patch 106 to slide the guide block 22 within the guide groove 21. Under the combined action of the guide groove 21 and the guide block 22, the sub-adhesive patch 106 is guided. At this time, under the elastic force of the telescopic spring 233, the arc-shaped locking groove 232 is activated. The movement causes the arc-shaped slot 232 to automatically engage with the corresponding arc-shaped clip 231. The engagement between the arc-shaped slot 232 and the arc-shaped clip 231 secures the sub-adhesive 106 and the first strap 104, allowing the size between the sub-adhesive 106 and the second strap 107 to be adjusted. This enables the fixation and protection belt to fix the ankles 113 of patients of different sizes, thus broadening its applicability and making it suitable for people of different ages, resulting in greater versatility.

[0036] Subsequently, the user pulls the anti-slip strap 103 on the surface of the protective strap body 1, causing the first strap 104 to move the connector 41 to one side of the protective strap body 1. Then, the user pulls the Velcro body 434, causing it to move to the surface of the connector 41. Under the action of the adhesive 42, the Velcro body 434 is adhered to the surface of the connector 41. At this time, the anti-slip pin 431 is engaged inside the anti-slip slot 432. Under the engaging action of the anti-slip pin 431 and the anti-slip slot 432, the connector 41 is secured. 1. When the fastener 41 is fixed to the Velcro body 434, the anti-loosening pin 431 drives the elastic clip 433 to automatically clip onto the inner wall of the Velcro body 434, preventing the fastener 41 and the Velcro body 434 from loosening. This effectively fixes the protective strap body 1 to the patient's leg, achieving the function of efficient fixation of the protective strap. This allows the protective strap to stably fix the patient's ankle 113 during use, resulting in better fixation of the patient's ankle 113.

[0037] Subsequently, when a patient with allergies uses the protective band body 1, the patient's ankle 113 may experience allergic reactions due to prolonged contact with the surface of the medical tape 111. At this time, the waterproof layer 33 provides a high degree of waterproofing to the surface of the medical tape 111, and the adhesive layer body 34 makes the waterproof layer 33 and the first anti-allergy adhesive layer 31 adhere more firmly. The combined action of the first anti-allergy adhesive layer 31 and the second anti-allergy adhesive layer 32 can prevent allergies on the surface of the patient's ankle 113, thus improving the effectiveness of the protective band body 1. This achieves the function of preventing allergies on the surface of the patient's ankle 113, making the protective band convenient for patients with allergic skin to wear, effectively preventing allergies, and making the protective band more practical. Finally, the use of the protective band is completed.
