[0041] Example 2

[0042] Referring to Figures 9-12 The difference between this embodiment and embodiment 1 is that the cross section of the air bag 2 is a circular ring, and the air bag 2 is provided with an opening 20, and the air bag 2 can be unfolded into a plane from the opening 20. The openings 20 of all the air bags 2 are located on the same straight line, and the openings 20 of the air bags 2 are provided with a first zipper 4. The first zipper 4 is parallel to the length direction of the main outer layer 1 or the main inner layer 3, and the length of the first zipper 4 is equal to the length of the main outer layer 1 or the main inner layer 3. The main outer layer 1 and the main inner layer 3 are both cut at the opening 20 of the air bag 2 to form a cut seam, and the edges of the cut seams of the main outer layer 1 and the main inner layer 3 are sewn with the first zipper 4. The right end of the main outer layer 1 is sewn with the right end of the main inner layer 3, and the left end of the main outer layer 1 is sewn with the left end of the main inner layer 3. In use, the first zipper 4 can be pulled to the end of the limb air bag (i.e. the position of the raised portion 10), at which time the limb air bag can be completely unfolded into a plane, and then the limb is placed above the unfolded limb air bag, and the first zipper 4 is pulled up again to complete the entire wearing process.

[0043] In this embodiment, the antibacterial core cover 8 is fixed to the main inner layer 3 or the auxiliary inner layer 21 by magic tape, and the antibacterial core cover 8 is provided with a plurality of male surfaces 14 with hooked elastic fibers, and the two ends of the main inner layer 3 and the end of the auxiliary inner layer 21 away from the raised portion 10 are both provided with a plurality of female surfaces 15 with soft fibers. The male surfaces 14 and the female surfaces 15 are bonded to realize the connection between the antibacterial core cover 8 and the main inner layer 3.

[0044] Embodiment 3

[0045] Referring to Figures 13-16 The difference between this embodiment and embodiment 2 is the fixing method of the antibacterial core cover 8 to the main inner layer or the auxiliary inner layer. The end of the antibacterial core cover 8 close to the raised portion 10 is connected to the main inner layer 3 by a third zipper 22, and the end of the antibacterial core cover 8 away from the raised portion 10 is connected to the main inner layer or the auxiliary inner layer by a fourth zipper 16.

[0046] Referring to Figure 7 As shown, the air bag b is inflated, and the remaining air bags except the air bag b are not inflated. The gas makes the air bag b expand, the main inner layer or the auxiliary inner layer contacts the skin of the limb and exerts a certain pressure on the limb, and at the same time, the stretchable portions on both sides of the air bag b also inflate and expand. The leftmost end of the air bag b passes the middle position of the adjusting cavity between the air bag a and the air bag b, and the rightmost end of the air bag b passes the middle position of the adjusting cavity between the air bag b and the air bag c. Then, the air bag b is deflated, and the air bag c is inflated. After the air bag c is full of gas, referring to Figure 8As shown, at this time, the leftmost end of the air bag bag c crosses the middle position of the adjusting cavity between the air bag bag b and the air bag bag c, and the air bag bag b in the inflated state and the air bag bag c in the inflated state form an overlapping area. Therefore, when the two adjacent air bag bags are inflated in sequence, there is no gap between the two adjacent air bag bags, and the air bag bag can press all parts of the limb, and has better treatment effect. At the same time, when the air bag bag is inflated, the side of the air bag bag close to the limb can be inflated radially inward until it is attached to the skin of the limb, so that even in the case of a user with a thin limb, the present application can also achieve the pressing of the limb, and has wide application range.

[0047] As can be seen from the above, the present application has better treatment effect, and the same specification product can be suitable for patients with different heights or thinness, and has wider application range. In addition, the present application is internally provided with a bacteria-proof core sleeve, which is convenient to use and is beneficial to prevent cross infection of the user.

[0048] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
