[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In a specific embodiment, such as Figs. 1-3 The basic operating procedure of the device is shown in the figure.

[0031] Elastic strip 1 and plastic strip 2 fixedly bonded to the outside of elastic strip 1;

[0032] The elastic band 1 has observation holes 3 equidistantly arranged inside, and the elastic band 1 and the plastic strip 2 are arranged in a cylindrical structure. There are six sets of elastic band 1 and plastic strip 2. At the same time, the two ends of the elastic band 1 and the plastic strip 2 are fixedly installed with winding tape 4.

[0033] The take-up tape 4 has a frustum-shaped structure, and the radius of the take-up tape 4 near the elastic tape 1 is larger than the radius of the take-up tape 4 away from the elastic tape 1.

[0034] When using this flap repair postoperative protection device, the device needs to be first put on the outside of the patient's limbs so that the elastic band 1 and the plastic strip 2 fit the outside of the patient's limbs. The distance between the elastic band 1 and the plastic strip 2 can be adjusted by the movement of the fixing cylinder 5 and the guide arc rod 7, so that the device can be used on the outside of the limbs of patients with different body types. The winding strap 4 is put on both ends of the elastic band 1 and the plastic strip 2 to prevent clothing or foreign objects from entering the gap between the patient and the elastic band 1, thereby improving the safety of the device.

[0035] In one specific embodiment, such as Figs. 1-6 The process of adapting the device to patients of different body types is shown in the figure.

[0036] A fixing cylinder 5 is fixedly installed on the outside of the plastic strip 2, and an installation groove 6 is opened inside the fixing cylinder 5, and a guide arc rod 7 is slidably installed inside the installation groove 6;

[0037] There are three sets of fixed cylinder 5 and guide arc rod 7 arranged at equal angles with respect to winding belt 4, and the length of fixed cylinder 5 is greater than the length of guide arc rod 7, and the two ends of guide arc rod 7 are located inside fixed cylinder 5;

[0038] The radius of the mounting groove 6 is larger than the radius of the guide arc rod 7, and both the guide arc rod 7 and the fixing cylinder 5 are made of hard plastic.

[0039] Two sets of extrusion rods 8 are installed on the internal threads of the fixed cylinder 5, and a rotating block 9 is fixedly installed on the end of the extrusion rod 8 away from the fixed cylinder 5, and the end of the extrusion rod 8 near the mounting groove 6 is in close contact with the guide arc rod 7.

[0040] The fixed cylinder 5 is correspondingly set with the extrusion short rod 8 and the rotating block 9. The fixed cylinder 5 and the elastic band 1 and plastic strip 2 on the outside of the guide arc rod 7 are distributed in three sets at the top, middle and bottom. The fixed cylinder 5 is in close contact with the elastic band 1.

[0041] When using this flap repair postoperative protection device, the device needs to be placed on the outside of the limb where the flap is being repaired. At this time, the fixing cylinder 5 and the guide arc rod 7 form the largest size loop. Then the fixing cylinder 5 and the guide arc rod 7 can move and reduce the distance between the two sets of fixing cylinders 5, so that the elastic band 1 and the plastic strip 2 can fit the outside of the patient's limb.

[0042] During this process, the rotating block 9 needs to be rotated, which in turn drives the compression rod 8 to rotate. The rotation of the compression rod 8 will cause it to move outward from the inside of the fixed cylinder 5, and the compression rod 8 will separate from the guide arc rod 7. At this time, the guide arc rod 7 can move inside the mounting groove 6, which will shorten the distance between the two adjacent fixed cylinders 5. The movement of the fixed cylinder 5 will drive the plastic strip 2 and the elastic band 1 to move. During this process, the radius of the cylinder formed by the elastic band 1 and the plastic strip 2 will decrease. After the elastic band 1 and the plastic strip 2 come into contact with the patient's limb, the movement between the fixed cylinder 5 and the guide arc rod 7 will stop. By rotating the rotating block 9 in the opposite direction, the compression rod 8 can be squeezed and positioned on the guide arc rod 7 again, thus completing the adjustment process of the device. This makes it easy to use for patients of different body types. Furthermore, by adjusting the fixed cylinder 5 and the guide arc rod 7 in different positions, the device can be adapted to different limb positions of the patient.

[0043] Meanwhile, the tightness of the device in contact with the patient's limb can be observed through the observation hole 3. The observation hole 3 can also be used to ensure the breathability of the device. Furthermore, the elastic band 1 is made of elastic material. When the elastic band 1 is stretched, the gap between the lines inside the elastic band 1 will increase, further ensuring the breathability of the device.

[0044] Based on the above embodiments, such as Figs. 1-5 As shown, the effect of the device in preventing foreign objects from entering at both ends is disclosed;

[0045] A tightening belt 10 and a loop fastener 12 are fixedly installed on the outer side of the winding belt 4. A pin fastener 11 is glued to one end of the tightening belt 10 near the loop fastener 12, and the pin fastener 11 is glued to the loop fastener 12.

[0046] Both the elastic band 1 and the winding band 4 are made of elastic fabric, and the gaps between the internal threads of the elastic band 1 will expand when it is stretched.

[0047] When using this flap repair postoperative protection device, the device needs to be put on the outside of the patient's limb. Then the size of the device can be changed by adjusting the fixing cylinder 5 and the guide arc rod 7. At this time, the winding belt 4 can be tightened so that the winding belt 4 seals and closes the two ends of the device.

[0048] During this process, the bonding position between the pin-side hook and loop fastener 11 and the loose-side hook and loop fastener 12 needs to be adjusted. At this time, the pin-side hook and loop fastener 11 and the loose-side hook and loop fastener 12 need to be separated and the tightening strap 10 needs to be pulled. The movement of the tightening strap 10 will cause the pin-side hook and loop fastener 11 to move, and then the pin-side hook and loop fastener 11 and the loose-side hook and loop fastener 12 can be bonded together, so that the winding strap 4 can be wound up, so that both ends of the device are in close contact with the patient's limbs, preventing foreign objects from entering the device and affecting its use, ensuring the safety of the device and increasing its overall practicality.

[0049] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
