Description

Technical Field

[0001] The invention relates to a wearable lymphedema drying and drainage device. Background Art

[0002] Lymphedema: Lower extremity lymphedema is swelling caused by a buildup of lymph fluid in the leg tissues, usually due to damage or blockage of the lymphatic system, which prevents the lymph fluid from circulating properly and returning to the bloodstream.

[0003] At present, the following solutions are usually adopted for the treatment of lymphedema: the first is to use an elastic sleeve to tighten it to prevent the edema from being too severe; the second is to use an air wave compression sleeve varicose vein instrument, which is similar to measuring blood pressure and discharges edema by applying pressure; the third is to drain it manually, that is, to squeeze the fluid accumulated at the distal end to the proximal end a little bit, which is effective but labor-intensive and inefficient.

[0004] Therefore, the best solution at present is the second one, which uses air wave pressurization. However, this solution cannot control the flow of the effusion at the distal end toward the proximal end. Specifically: 1. The pressurization sleeve is cylindrical, but the human legs or arms are irregular in shape. Therefore, when the airbag is inflated, the actual force is uneven. This will result in: originally, the effusion was intended to run from the feet to the hips, but during the process of pressurizing the calves or thighs, the effusion ran to the back of the thighs after being compressed in the front, instead of running to the hips. 2. During the pressurization process, the entire leg is subjected to circular force. When the upper circle is pressurized, the effusion will run to both ends. In order to make the effusion run in one direction, the airbags are inflated one by one to squeeze the effusion in one direction. However, the interval between each airbag is large. During the squeezing process, a part of the effusion will remain in the gap between the two airbags (the amount is relatively large). Figure 5 As shown, the accumulated fluid will remain in the gap of the blue box; 3. Long-term squeezing will cause moisture and itching in the legs due to the lack of air permeability; 4. Without temperature heating, the fluid flowability is poor. Summary of the invention

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] like Figure 1-4 As shown, this embodiment provides a wearable drying and drainage device for lymphedema, which is composed of a pressurized sleeve 1, an air pump 11, a drying box 10, an air pump 11 and a controller 12.

[0023] like Figure 1 and 3 As shown, the compression sleeve 1 is composed of a skin-contacting layer 4, a heating layer 5, a heat-insulating layer 6, an inner airbag 3, an outer airbag 2 and an outer fabric 7. The skin-contacting layer 4, the heating layer 5, the heat-insulating layer 6, the inner airbag 3, the outer airbag 2 and the outer fabric 7 are arranged in sequence from the inside to the outside. In this embodiment, there are multiple independently controlled outer airbags 2 and multiple independently controlled inner airbags 3, and the outer airbags 2 and the inner airbags 3 are arranged alternately and distributed along the axial direction of the limb. The multiple independently controlled outer airbags 2 and the multiple independently controlled inner airbags 3 respectively have airbag interfaces 14 for connecting to the inflation pump pipeline and electrically connecting to the controller 12.

[0024] like Figure 1 As shown, the compression sleeve 1 is fixedly provided with 6 inner support tubes 8 along the axial direction of the limb, and the 6 inner support tubes 8 are evenly distributed along the circumference of the limb, and the inner support tubes 8 are arranged between the skin-contacting layer 4 and the heating layer 5. Figure 2 and 4 As shown, the inner support tube 8 is fixedly provided with a plurality of exhaust pipes 9 along the axial direction of the limb, and the exhaust pipes 9 penetrate the skin-contacting layer 4. The inner support tube 8 is fixedly provided with two exhaust pipes 9 along its circumference, and the angle between the two exhaust pipes 9 is a, wherein 120°≤a≤150°, and the bisector of the angle between the two exhaust pipes 9 passes through the axis of the limb.

[0025] like Figure 1As shown, one end of the inner support tube 8 is connected to the air outlet of the drying box 10 through the air flow tube, the air inlet of the drying box 10 is connected to the air outlet of the air pump 11, and the air inlet of the air pump 11 is connected to the other end of the inner support tube 8 through the air flow tube.

[0026] The heating operation of the heating layer 5 is controlled by the controller 12. The inflation and deflation operations of the plurality of outer airbags 2 and the plurality of inner airbags 3 are respectively controlled by the controller 12. The pressurizing sleeve 1 is provided with a Velcro fastening opening 13.

[0027] Each outer airbag 2 and each inner airbag 3 are controlled independently. Along the direction from the distal end to the proximal end, the inner airbag 3 farthest from the heart is first inflated to the specified pressure and maintained for the specified time. Then, the outer airbag 2 adjacent to the inner airbag 3 is inflated to the specified pressure, and then the inner airbag 3 is deflated. After the outer airbag 2 is maintained for the specified time, the inner airbag 3 adjacent to the outer airbag 2 is inflated to the specified pressure, the outer airbag 2 is deflated, and the inner airbag 3 is maintained for the specified time. This pattern is followed until the airbag closest to the heart is inflated, maintained for the specified time, and then deflated, thereby completing one cycle of progressive airbag drainage and compression.

[0028] Therefore, the compression sleeve 1 has a double-layer airbag, each of which is independently controlled, and can squeeze the tissue fluid from the distal end to move the tissue fluid toward the proximal end, pushing and squeezing the tissue fluid from the limbs to the trunk. Since the inner airbag 3 and the outer airbag 2 are staggered, it can be avoided that the accumulated fluid is retained in the gap between adjacent annular airbags.

[0029] A plurality of inner support tubes 8 are arranged inside the compression sleeve 1, and the inner support tubes 8 are arranged along the axial direction of the limb. When the airbag is inflated, the inner support tubes 8 can prevent the tissue fluid from temporarily diffusing in the peripheral direction when the limb is compressed, and the adjacent inner support tubes 8 limit the flow direction of the tissue fluid, that is, the flow direction of the tissue fluid is limited to: distal end → proximal end. Therefore, the function of the inner support tubes 8 is to form a circumferential barrier, so that the accumulated fluid can move along the axial direction of the limb (such as the leg).

[0030] The compression sleeve 1 is provided with ribs at the position of the inner support tube 8 (i.e., the inner support tube 8 is used to fill the middle of the ribs). Since the ribs are under the greatest pressure, the pores on the body surface are easily uncomfortable if they are under pressure for a long time, so an exhaust port is added at this position. Therefore, the discomfort caused by long-term pressure can be avoided, ensuring that the pores can have sufficient oxygen supply; moisture can be taken out, because when squeezing lymphatic effusion, part of the effusion will be discharged in the form of sweat; if the exhaust port of the inner support tube 8 is blown with large-flow pulse gas, the gas will impact the compressed skin surface, which can form a certain vibration-like effect. Through the vibration, the part of the effusion compressed in the corner of the rib can be vibrated to move outward and then discharged by the airbag.

[0031] The controller 12 controls the air pump 11 to operate, driving the air flow in the inner support tube 8 so that the exhaust port discharges the flowing gas and takes away the moisture. At the same time, the controller controls the heating wire to heat the air in the inner support tube 8 so that the exhaust port discharges the warm gas.

[0032] The controller 12, in addition to independently controlling the airbags, is also connected to each inner support tube 8. The controller 12 can control the heating wire to heat the air, ensuring that the air discharged from the exhaust port is warm gas, and cooperate with the baking therapy during the pressure squeezing process. Because the ribs squeeze the skin, the skin effusion at this position will have a small amount of exudation, so heating can avoid sweating and keep the skin dry; heating can also promote body fluid circulation and accelerate lymph return.

[0033] A drying box 10 is added to the air flow loop of the air pump 11 to remove moisture.

[0034] The compression sleeve 1 is provided with a heating wire and a heat preservation layer 6, wherein the heating wire can be replaced by a heating film. After the heating wire / heating film heats to a specified temperature, the temperature is maintained, so that the internal temperature of the entire compression sleeve 1 is maintained at a set temperature (such as 50°), and the capillaries are expanded by heat to promote the return of lymph fluid.

[0035] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present invention without departing from the content of the technical solution of the present invention should be included in the protection scope of the present invention.
