Description
Technical Field
The present invention relates to the field of medical devices, and more particularly to a compression system for treating varicose veins in the lower extremities.
Background
When superficial or deep veins of the legs of a human body are blocked or the valves are not locked, chronic venous insufficiency is caused, and leg blood cannot effectively flow back to the heart through the veins. This can lead to varicose veins in the lower extremities. Varicose veins tend to occur first, typically in low-lying areas, such as the lower leg.
Some people are required to keep a similar posture for a long time due to various reasons such as professional needs in daily life, and the like, and the people are easy to suffer from varicose veins of lower limbs. Once the varicose vein condition continues to progress, a series of complications may occur, such as (1) nutritional changes in the skin: thinning of the skin, desquamation, itching, pigmentation, eczematous dermatitis and ulceration (e.g. the so-called old rotten leg (i.e. venous ulcer)). (2) Superficial thrombophlebitis: the varicose veins are painful, presenting red, swollen, hard nodules and cords, and have tenderness. (3) Bleeding: acute bleeding is caused by trauma or spontaneous rupture of varicose or small veins. (4) Secondary infection: secondary infections are likely to occur due to weakened patient resistance. The common symptoms are superficial thrombophlebitis, erysipelas, acute cellulitis, elephantiasis and the like. Therefore, it is very important to treat varicose veins.

In another preferred embodiment, the adhesive regions are distributed on both side regions of the wrapping region, and the adhesive regions can be implemented by using Velcro, which has fine and soft fibers and round hairs (LOOP) on one side and harder barbed Hairs (HOOK) on the other side.
In another preferred embodiment, the compression system is a lightweight thin blend of polyurethane and nylon, or is made of polyurethane and Pebax, etc.
In another preferred embodiment, the wrapping region is composed of an outer layer of polyurethane and an inner layer of nylon.
The wrapping area of the invention mainly comprises a part wrapping the lower leg and a part wrapping the sole.
In another preferred embodiment, the interior of the wrapping region has a bladder made of nylon.
In another preferred embodiment, the outside of the wrapping area is provided with two polyurethane wear-resistant outer layers, and the nylon air bag is arranged between the two polyurethane wear-resistant outer layers.

In another preferred embodiment, when the wrapping region is laid flat, the outermost edge is fusion sealed along the entire edge to isolate the bladder from the environment.
When the pressurization ball is pressurized manually, the working mechanism of the corresponding pressure gauge is as follows:
the pressure gauge of the pressurizing part is provided with an upper cover which is provided with a plurality of pressure limiting areas, such as: high (pressure) pressure limiting area, medium (pressure) pressure limiting area, low (pressure) pressure limiting area, zero (pressure) pressure limiting area (i.e. exhaust hole), etc.
The pressure limiting area is provided with a plurality of parts of an upper cover pressure limiting hole, a pressure limiting valve assembling hole and a pressure limiting valve; the pressure limiting valve is assembled on the pressure limiting valve assembling hole of the upper cover, wherein the pressure limiting valve is used as a controller and is used for controlling the pressure not to exceed the maximum bearing pressure value of the pressure limiting valve.
When the upper cover is provided with the high, middle, low and zero pressure limiting areas: the high, middle, low and three pressure limiting areas are provided with pressure limiting valves, the pressure limiting values of the pressure limiting valves of various areas are different, and the different pressure limiting values of the pressure limiting valves enable the pressure limiting areas to form different pressure limiting functions, such as the requirements of high, middle and low pressures; the zero pressure limiting region is not equipped with a pressure limiting valve.
When the pressure born by each pressure limiting valve exceeds the pressure limiting value of the pressure limiting valve, the pressure limiting valve can release pressure; the pressure limiting valve has an excessive pressure relief function, so that the required pressure cannot be exceeded during pressurization.
After the upper cover of the pressure gauge is removed, a pressure channel is arranged on the pressure gauge, and a pressure limiting hole of the pressure channel is arranged on the pressure channel.
The outer ring of the pressure limiting hole of the pressurizing channel is provided with a sealing ring. The sealing ring is used for ensuring the sealing performance when various pressure limiting areas on the upper cover are assembled with the pressure limiting hole of the pressure limiting channel of the pressure gauge.
Particularly, when the pressure limiting hole of the pressurizing channel on the pressurizing channel is aligned with the pressure limiting hole of the upper cover, the gap part of the pressurizing channel and the pressure limiting hole of the upper cover is filled by the sealing ring, and the pressure limiting hole of the pressurizing channel is only the same as the pressure limiting hole of the upper cover. When the pressure is applied, the pressure medium can pass through the pressure limiting hole of the pressure channel and then the pressure limiting hole of the upper cover.
When the pressure limiting valve is not assembled on the pressure limiting valve assembling hole of the upper cover, the pressure medium can be communicated to the outside through the pressure limiting hole of the pressure channel on the pressure channel and then through the pressure limiting hole of the upper cover. This is the case when the zero pressure limiting region is not equipped with a pressure limiting valve, i.e. when the zero pressure limiting region acts as a vent.
When the pressure limiting valve is assembled on the pressure limiting valve assembling hole of the upper cover, the pressurizing medium passes through the pressurizing channel pressure limiting hole on the pressurizing channel and then passes through the pressure limiting hole of the upper cover to reach the pressure limiting valve, and the medium is blocked by the pressure limiting valve and can only extend to the air bag of the joint and finally reach the wrapping area from the connecting pipe. This is the case when the high, medium, low and three pressure limiting zones are equipped with pressure limiting valves.

As shown in fig. 10 to 12, the electric pressurizing ball 19 has a power switch button, a pressure display area, a pressure setting area, an air inlet port, an air outlet port, and a charging port on the outside thereof.
The power supply of the built-in power supply of the electric pressurizing ball 19 is controlled by the power switch key, and the charging port is used for charging the built-in power supply from the outside. The set value and the actual value of the pressure can be observed through the pressure display area. The pressure setting area is provided with three keys of 'less', 'inverted V' and 'V' which are respectively used for selecting a certain pressure value required to be set, an 'increasing pressure value' and a 'reducing pressure value'. The air outlet port is connected with a connecting pipe 6, and the front end of the connecting pipe 6 is provided with a joint 7. The joint 7 may be connected to a non-return valve of the pressurized system.
The electric pressurizing ball is internally provided with a booster pump part and a built-in power supply part. The power line is communicated between the power supply and the booster pump, and then the built-in power supply part supplies power to the booster pump part, so that the booster pump part is in a working state. The booster pump is provided with a pressure monitoring module and a pressurizing module, and when the pressure monitoring module finds that the actual pressure does not reach the set pressure, the pressurizing module is signaled to pressurize. The booster pump pressurizes until a set value, and then stops pressurizing.
All documents referred to herein are incorporated by reference into this application as if each were individually incorporated by reference. Furthermore, it should be understood that various changes and modifications of the present invention can be made by those skilled in the art after reading the above teachings of the present invention, and these equivalents also fall within the scope of the present invention as defined by the appended claims.
