Description

Technical Field

[0001] This application relates to the technical field of elastic bandages, and particularly to a tubular bandage. Background Art

[0002] Varicose veins of the lower extremities is a common disease that mainly affects the adult population, with a prevalence rate between 5% and 30%, and it increases with age. It is estimated that there are more than 200 million varicose vein patients in China. One of the key methods for treating varicose veins of the lower extremities is compression therapy, which promotes the return of venous blood by applying a certain pressure to the lower extremities, accelerates the absorption of inflammatory reactions, and thus relieves clinical symptoms. Commonly used compression therapy methods include pressure bandages, intermittent pneumatic compression pumps (IPC), and pressure socks, etc. However, each of these methods has limitations.

[0003] The pressure bandage is a traditional compression therapy method. Although the multi-component bandage is effective, its components are complex and the adjustment steps are cumbersome, resulting in low patient acceptance. The pressure sock promotes the return of venous blood by applying a series of gradient pressures to the lower extremities, relieves the increased venous pressure, improves the function of the skeletal muscle pump, and promotes lymphatic return. However, the structure of the pressure sock body is fixed, the pressure value is not easy to adjust, and the production cost of the pressure sock with intelligent pressure adjustment is relatively high, and the market acceptance is not large.

Detailed implementation mode

[0026] The following is a further detailed description of this application in combination with the attached Figure 1-6 drawings.

[0027] Embodiment 1

[0028] The embodiment of this application discloses a tubular bandage, and the tubular bandage is a medium tube type that passes above the knee above the lower leg. Refer to Figure 2 FIG. 1, a tubular bandage, includes a lower leg part 1, an ankle part 10, and a foot sole part 2 that are connected in sequence. A plurality of first pressure layers 3 are provided on the outer surface of the lower leg part 1 corresponding to the area between the center of the patella and the popliteal fossa to the insertion point of the gastrocnemius muscle. An elastic tightening design can be added at the opening of the lower leg part 1 to prevent the lower leg part 1 from slipping below the knee.

[0029] Optionally, the first pressure layer 3 is a fully enclosed structure and is fixedly connected to the lower leg part by means of sewing or bonding, etc.

[0030] In this structure, relying on the double-layer pressurization of the first pressure layer 3 and the lower leg part 1, the pressure borne locally on the inner side of the lower leg can be increased. Especially when the first pressure layer 3 is arranged between the center of the patella and the popliteal fossa to the insertion point of the gastrocnemius muscle, it centrally covers the human body parts where varicose veins are more likely to occur in the gastrocnemius muscle and soleus muscle of the lower leg. Therefore, by appropriately increasing the pressure of the first pressure layer 3, the venous return of the intermuscular veins of the lower leg is promoted.

[0031] Preferably, the first pressure layer 3 is trapezoidal in shape with a wider upper part and a narrower lower part.

[0032] The pressure of the tubular bandage on the human body from the ankle to the thigh is a gradient pressure, and the pressure gradually decreases from the ankle to the thigh. The pressure at the ankle is the largest at 100%, 70% - 90% at the back of the lower leg, and 25% - 45% at the thigh part. This gradually decreasing pressure gradient can not only promote the venous blood to return to the heart, but also relieve the increased venous pressure, improve the function of the skeletal muscle pump, and promote lymphatic return.

[0033] When the first pressure layer 3 is of other shapes, it can also achieve a certain pressurizing effect. However, when it is a trapezoid with a wider upper part and a narrower lower part, since the area at the lower part is narrower, the pressure is more concentrated, and the area at the upper part is wider, so the pressure is more dispersed compared to the lower part, which conforms to the gradient pressure and the blood flow direction of the human body. Therefore, it can achieve the best pressurizing effect compared to other shapes.

[0034] The first pressurizing layer 3 can be made of the same or different materials as the calf part 1, and is adjusted based on actual production applications.

[0035] Optionally, the first pressure layer 3 is detachably fixed to the tubular bandage by means of a zipper, a magic tape, a snap fastener, etc. In this structure, a pressurizing material can be stuffed into the first pressure layer 3 to further enhance the pressure generated on the local part of the calf part 1.

[0036] Embodiment 2

[0037] The embodiment of the present application discloses a tubular bandage, which is a long tube type after adding a thigh part. Refer to Figure 3 and Figure 6 , a tubular bandage includes a calf part 1, an ankle part 10, and a foot part 2 connected in sequence. A plurality of first pressure layers 3 are provided on the calf part 1 corresponding to the area between the center of the patella and the popliteal fossa to the insertion point of the gastrocnemius muscle. The upper end of the calf part 1 is provided with a thigh part 4, and the second pressure layer 5 is provided on the outer surface of the thigh part 4 corresponding to the adductor muscle group in the human body.

[0038] Optionally, the first pressure layer 3 is a fully enclosed structure and is fixedly connected to the calf part by means of sewing or bonding, etc. The second pressure layer 5 is a fully enclosed structure and is fixedly connected to the thigh part by means of sewing or bonding, etc.

[0039] In this structure, relying on the double-layer pressurization of the first pressure layer 3 and the calf part 1, the pressure borne by the local part of the inner calf can be increased. Especially for the human body parts where the incidence of varicose veins in the gastrocnemius muscle and soleus muscle of the calf is relatively high, the pressure can be appropriately increased through the first pressure layer 3 to promote the venous return of the intermuscular veins of the calf. The structure of the second pressure layer 5 is similar to that of the fully enclosed first pressure layer 3. In this structure, relying on the superimposed pressure of the second pressure layer 5 and the thigh part 4, the thigh is pressurized to increase the pressure borne by the local part of the inner thigh and promote the venous return of the inner thigh and vulva.

[0040] Optionally, the first pressure layer 3 is detachably fixed to the tubular bandage by means of a zipper, a magic tape, a snap fastener, etc. The second pressure layer 5 is a fully enclosed structure and is fixedly connected to the thigh part by means of sewing or bonding, etc.

[0041] In this structure, a pressurizing material can be stuffed into the first pressure layer 3 to achieve adjustable pressure, and the second pressure layer 5 and the thigh part 4 use the strong pressure generated by the double-layer material to achieve local pressurization of the inner thigh.

[0042] Optionally, the first pressure layer 3 is a fully enclosed structure and is fixedly connected to the calf 1 by means of stitching or bonding. The second pressure layer 5 is detachably fixed to the tubular bandage by means of a zipper, a magic tape or a snap fastener.

[0043] In this structure, the first pressure layer 3 and the calf 1 apply stronger pressure using a double-layer material; the thigh 4 can achieve adjustable pressure by filling a pressure-applying material in the second pressure layer 5.

[0044] Optionally, both the first pressure layer 3 and the second pressure layer 5 are detachably fixed to the tubular bandage by means of a zipper, a magic tape or a snap fastener.

[0045] In this structure, the local pressure can be adjusted by filling a pressure-applying material in both the first pressure layer 3 and the second pressure layer 5. This structure is the most flexible and convenient for doctors to adjust according to different conditions of patients.

[0046] Preferably, the shape of the first pressure layer 3 is a trapezoid that is wider at the top and narrower at the bottom. It conforms to the gradient pressure and the blood flow direction of the human body and can achieve the best pressure-applying effect. The second pressure layer 5 is a long strip corresponding to the muscle pulling direction of the adductor muscle group in the human body.

[0047] The first pressure layer 3 and the second pressure layer 5 can also be set to other shapes as long as they can achieve the pressure-applying effect, without excessive restrictions, and are all within the protection scope of this application.

[0048] Embodiment 3

[0049] Based on Embodiment 2, referring to Figure 3 and Figure 6 , an anti-slip structure is installed on the thigh 4, and the anti-slip structure adopts an anti-slip structure 8 and / or a suspension assembly 9;

[0050] Among them, the anti-slip structure 8 is configured as an anti-slip strip or anti-slip points that fit the upper inner surface of the thigh skin. The anti-slip structure 8 can increase the friction with the human skin and prevent the tubular bandage from slipping.

[0051] The suspension assembly 9 includes a waist and abdomen 902 for fixing to the human waist and abdomen or other positions. The waist and abdomen 902 is connected to the thigh 4 by a plurality of connecting bands 901. To prevent the tubular bandage from slipping, the waist and abdomen 902 can be fastened to the human waist and abdomen or other positions by means of a magic tape, a zipper, a snap fastener, a rope binding or other means to achieve the effect of pulling the tubular bandage upward.

[0052] Embodiment 4

[0053] This application embodiment discloses a tubular bandage. Referring to Figure 3-6, A tubular bandage, comprising a calf portion 1, an ankle portion 10, and a foot sole portion 2 that are connected in sequence. A plurality of first pressure layers 3 are provided on the calf portion 1 corresponding to the area between the center of the patella and the popliteal fossa to the insertion point of the gastrocnemius muscle. The upper end of the calf portion 1 is equipped with a thigh portion 4, and a second pressure layer 5 is provided on the surface of the thigh portion 4 corresponding to the inner side of the human thigh.

[0054] Refer to Figure 3 and Figure 6 , An anti - detachment structure is installed on the thigh portion 4, and the anti - detachment structure adopts an anti - slip structure 8 and / or a suspension assembly 9;

[0055] Among them, the anti - slip structure 8 is configured as an anti - slip strip or anti - slip points that fit the upper inner surface of the thigh skin.

[0056] The suspension assembly 9 includes a waist and abdomen portion 902 for fixing on the human waist and abdomen or other positions, and the waist and abdomen portion 902 is connected to the thigh portion 4 through a plurality of connecting bands 901.

[0057] Refer to Figure 4 , The first pressure layer 3 and / or the second pressure layer 5 are installed with openings on the upper side or side. A pressurizing object is installed inside the first pressure layer 3 and / or the second pressure layer 5. Since the first pressure layer 3 and / or the second pressure layer 5 have openings, pressurizing objects can be stuffed to enhance the local pressure on the human skin, achieving the effect of centripetal pressurization. Since the pressurizing objects can be installed according to different standards, doctors can fill the pressurizing objects that meet the patient's needs based on experience or established standards, thereby strengthening the local pressure on the legs and improving venous blood return.

[0058] Refer to Figure 5 , When the pressurizing object is an adjustable pressure assembly 7, the adjustable pressure assembly 7 includes an inflatable air cushion 701 for pressurization. A gas source device for inflation and deflation is connected to the inflatable air cushion 701. The gas source device includes a conduit 702 communicating with the inflatable air cushion 701. A three - way pipe 703 is connected to the conduit 702. The other two ends of the three - way pipe 703 are respectively connected to a manual air pump 704 and a deflation valve 705. The manual air pump 704 is composed of an air bag and one - way valves installed at the air inlet and outlet at both ends of the air bag. By pressing the air bag of the manual air pump 704, gas enters the interior of the inflatable air cushion 701 through the conduit 702, causing the inflatable air cushion 701 to bulge and locally pressurize the calf muscle position opposite the pressurizing layer. When releasing pressure, just open the deflation valve 705.

[0059] Refer to Figure 4, the pressing object is an object with certain elasticity and hardness such as rubber and sponge, which can apply a strong pressure. When performing sclerotherapy on varicose veins and capillary dilation, the pressing object can also be configured as a cryogenic object for short-term use, which can significantly reduce the occurrence of known adverse events after vein sclerotherapy, such as ecchymosis, pigmentation, and the formation of new blood vessels. Through the above technical solution, it can also be applied to postoperative subcutaneous ecchymosis and hematoma, and reduce bleeding and hematoma formation in a timely manner by applying pressure after stripping the main saphenous vein.
