[0021] Embodiment:

[0022] As Figure 1 and 2 shown, in this embodiment, the limb compression sleeve includes: a first outer layer 1, a second outer layer 2, an air inlet pipe 4, and an inner partition 3 forming a first airbag 7. The first outer layer 1 and the second outer layer 2 enclose to form a second airbag 8; the inner partition 3 is provided with a ventilation hole 31 communicating the first airbag 7 and the second airbag 8; the air inlet pipe 4 is used to connect with an external air supply device to realize inflation and deflation of the limb compression sleeve, and one end of the air inlet pipe 4 is located inside the first airbag 7, and the other end passes through the first airbag 7 and extends to the outside.

[0023] Two airbags are provided in the limb compression sleeve of this embodiment, that is, the first airbag 7 and the second airbag 8. The first airbag 7 and the second airbag 8 are communicated through the ventilation hole 31; during use, the first airbag 7 is instantaneously and rapidly inflated, and can reach the peak value in a short time. Then the gas flows along the ventilation hole 31 to the second airbag 8, and then the second airbag 8 reaches the peak value. This setting method of the multi-airbag structure can achieve buffering under pressure and continuous treatment, which is beneficial to greatly improving the user experience. And the limb compression sleeve of this embodiment has a simple structure and is more convenient to use.

[0024] The limb compression sleeve of this embodiment can be a pressure sleeve for treating positions such as the hand and calf. The external air supply device can be an anti-thrombosis treatment instrument, and the limb compression sleeve can be periodically charged and discharged through the air inlet pipe 4. That is, during formal treatment, the air inlet pipe 4 of the limb compression sleeve is connected to the anti-thrombosis treatment instrument, and the anti-thrombosis treatment instrument inflates and deflates (inhales) in a certain way, so as to control the orderly flow of gas in the device, and apply the air pressure to the patient according to the set pressure, time, and sequential order, forming a "squeezing" effect with periodicity, directionality, gradualness, and accumulativeness, so as to realize the treatment of the patient, and can be used for parts such as the hand and calf, with wide applicability.

[0025] In the present embodiment, a first sponge block 5 is further provided in the first airbag 7, a clearance groove is provided on the sponge block, and one end of the air inlet pipe 4 is located in the clearance groove. The sponge is soft, which can improve the comfort of use. Furthermore, a second sponge block 6 is further provided in the second airbag 8, which can further improve the physical sense of use. In the present embodiment, the volume of the first airbag 7 is smaller than the volume of the second airbag 8, and correspondingly, the volume of the first sponge block 5 is smaller than the volume of the second sponge block 6. In a specific embodiment, the volume of the first sponge block 5 can be half the volume of the second sponge block 6. Such an arrangement can realize the sequential inflation of multiple airbags, coupled with the buffering effect of the sponge structure, compared with the limb compression sleeve of a single airbag, the physical sense of the user is greatly improved.

[0026] In this embodiment, the inner partition 3 is TPU fabric, and TPU (Thermoplastic polyurethanes) is thermoplastic polyurethane elastomer rubber. It is mainly divided into polyester type and polyether type, and has the characteristics of environmental protection, wear resistance, easy processing, and good impact resistance. The first outer surface layer 1 can be a quadrilateral or a rounded quadrilateral without limitation. The first outer surface layer 1 includes a flannel layer and a TPU layer bonded to the flannel layer, and the second airbag 8 is located on the side of the TPU layer away from the flannel layer, that is, the raw material of the first outer surface layer 1 can be flannel bonded to TPU, and has excellent strength, compression performance, resilience, and flexure resistance. Furthermore, the flannel layer can be nylon, or a combination of nylon and PP materials, with low raw material cost and easy processing. In this embodiment, the second outer layer 2 can be used as the main fabric of the limb compression sleeve and can be fan-shaped; the area of ​​the first outer layer 1 can be smaller than the area of ​​the second outer layer 2, that is, a part of the second outer layer 2 is a functional area enclosed with the first outer layer 1, and the other part is an extended area connected to the functional area, so that the limb pressure sleeve has enough length to enclose and fix the patient's limb. The second outer layer 2 can be made of nylon or nylon fabric, which has excellent characteristics of wear resistance, high strength, and good elastic recovery ability.

[0027] In this embodiment, the limb compression sleeve as a whole can be a fan-shaped structure, which is more suitable for the shape of human limbs. The airway can be set at one end of the limb compression sleeve. In some specific embodiments, a Velcro hook surface and a Velcro velvet surface can be set on the surface of the second outer layer 2, so that during the working process, when the patient's limb compression sleeve is wrapped around the periphery of the limb, the Velcro hook surface and the Velcro velvet surface can be adhered to each other, thereby achieving the fixation between the limb compression sleeve and the patient's limb. It can be understood that in some specific embodiments, the second outer layer 2 itself has the properties of the Velcro velvet surface, that is, the Velcro hook surface can be added to the second outer layer 2, which has a simple structure and is easy to use.

[0028] In this embodiment, the limb compression sleeve is an integrated hot-pressed molded part, which can be prepared by a high-frequency pressing process. The high-frequency pressing process takes less time than the conventional sewing process, which can improve production efficiency and reduce production costs. Specifically, it can be prepared in the following ways: 1. Fold the TPU fabric (the raw material of the inner partition 3) used to form the first airbag 7 in half, and sandwich the first sponge block 5 in the gap of the TPU fabric, and then insert one end of the ventilation tube into the give way groove to form an intermediate component; 2. Place the second sponge block 6 on the second outer layer 2 fabric, and put the folded intermediate component on top of the second sponge pad; 3. Cover the top of the intermediate component with a TPU-fitting flannel (the raw material of the first outer layer 1); 4. Use high frequency pressing to obtain the required limb compression sleeve. In this way, only one process is required to press and form the limb compression sleeve, which is conducive to reducing processing costs and has high production efficiency.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
