Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a multifunctional leg sleeve for auxiliary treatment of lower limb lymphedema. Background Art

[0002] According to statistics from the World Health Organization, there are approximately 250 million lymphedema patients worldwide, of which 170 million suffer from secondary lymphedema. Lymphedema ranks 11th among common diseases and 2nd among disabling diseases. It is a highly disabling, progressive disease. Lymphedema is a disease caused by the inability of the lymphatic system to secrete lymph fluid normally. Common varicose veins and thrombosis can affect the normal flow of lymph fluid and cause lymphedema. Lymphedema can cause swelling in local areas such as the arms, legs, neck, trunk or pelvis, and the skin becomes thicker, harder and even rougher. When lymphedema causes local tissue compression and nerve damage, patients may feel pain or discomfort, and their arms cannot be straightened, walking is difficult and other motor function impairments may occur. In even worse cases, local infections may occur, endangering life and health.

[0003] At present, the most widely used method in the world is the comprehensive decongestion therapy of lymphedema with manual drainage, namely CDT (complete decongestion therapy), which is the current standard treatment method for lymphedema. CDT includes skin hygiene and care, manual lymphatic drainage, special multi-layer bandage pressure dressing, special pressure pantyhose arm sleeves, decongestion exercise and self-treatment education. Pressure therapy is an important technology for the treatment of edema and lower extremity venous and lymphatic diseases. Compression stockings have become a convenient, effective and non-traumatic pressure medical product. As a common implementation method of pressure therapy, compression stockings should meet the following conditions: ① adapt to the different length, circumference and curvature changes of various parts of the human body; ② the pressure value and pressure distribution of pressure stockings in different parts of the human body should also be different; ③ pressure comfort. Traditional commercial medical compression stockings are all mass-produced and cannot meet the specific size and shape of the affected limb. Patients choose limited fixed sizes and cannot accurately apply pressure, which restricts their widespread use among the elderly. Previous studies have focused on the effects of pressure stockings on skin thickness, venous blood flow velocity and pain after edema, and there are few observations on the efficacy of pressure stockings in improving functional disorders. Although considered effective, decompression physical therapy is time-consuming, inconvenient to perform, expensive, and has low patient compliance and satisfaction.

[0004] At present, researchers use air pressure as a power to intermittently or continuously pressurize local limbs as a method to treat limb lymphedema. Researchers use pneumatic pressure devices to prepare and inject gas into a series of overlapping air bags to form an expanding pressure gradient. These air bags are placed on the limbs of the person being treated. Under the control of the instrument, they are gradually pressurized in sequence to compress the proximal end of the edema and promote the reflux and absorption of the edema. Researchers use a circulating limb pressurizer to perform mechanical massage on the patient's limbs using reciprocating air pressure as a power source. With the optimization of technology, corresponding products are continuously optimized and upgraded, such as air bag pulsating air pressure therapy devices, air wave negative pressure therapy devices, circulating pressure therapy devices or gradient pressure therapy devices, etc., which continue to promote air pressure intervention treatment of lymphedema. This series of instruments is generally an air bag air pressure therapy device consisting of a main unit and an air bag. By repeatedly inflating and deflating the multi-chamber airbag in sequence, circulatory pressure is formed on the limbs and tissues, promoting the return of venous blood and lymph fluid in the limbs, and effectively treating lower limb swelling caused by lymphatic vessel damage due to various reasons such as limb lymphedema, lymphangitis, and venous surgery.

[0005] The airbag device used in the current air wave pressure therapy device can effectively solve the problem of elastic attenuation of the fabric. For example, the Chinese patent application number CN 111743751 A published a portable deep vein thrombosis air wave pressure therapy device with massage function and the Chinese patent authorization announcement number CN 206630859 U published a gradient pressure therapy device, which uses an inflatable airbag to perform circular pressing of each cavity according to the treatment mode set by the program, and forms a pressure gradient inside the human body through the reciprocating process of inflation-expansion-extrusion-deflation, which promotes venous circulation and eliminates lymph edema. However, there are still problems such as insufficient fit between the airbag device and the treatment site, and mismatch between the pressure and the pressure area. In addition, the single pressurization function limits the wide promotion of this series of products. In comparison, the present invention uses an annular layered airbag, and each level of the airbag operates independently, can be pressure-regulated according to the doctor's prescription, and has a wide range of regulation, and has a higher fit and adaptability to the human body. In addition, the present invention also incorporates multiple functions such as medicinal heating and electrical stimulation therapy, which effectively improves the functionality and integration of the leg sleeve.

[0042] Example 2

[0043] Based on Example 1, the working process of a multifunctional leg sleeve for auxiliary treatment of lower limb lymphedema includes:

[0044] Step 1, wear the multifunctional leg sleeve on the patient's leg;

[0048] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0049] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
