A physiotherapy instrument for human facet joint inflammation

Abstract

A physiotherapy instrument for human facet joint inflammation, relating to the technical field of medical treatment equipment, including a hard treatment chamber and a negative pressure generation control system, at least one opening for limbs to be inserted and extended is provided on the treatment chamber, and the treatment chamber passes through the air The channel is connected to a negative pressure generation control system. The treatment chamber is L-shaped, which can be used for limbs to be placed after the knee-up thigh part and the knee-down calf part or all are bent, and for the elbow part to go up and the elbow to go down. A part or all of the lower bladder is bent and put in; the L-shaped treatment cavity is composed of several parts that cooperate with each other; the opening of the treatment cavity and the limbs are fixed by a sealed connection component. The invention is light, easy to operate in and out of the limbs, completely eliminates the radial pressure, and greatly improves the therapeutic effect.

Description

Technical field [0001] The invention relates to the technical field of medical treatment equipment, in particular to the use of negative pressure and an L-shaped treatment chamber to treat human small joint inflammations such as knee arthritis, elbow joint inflammation, hand and foot joints or Raynaud's disease. Background technique [0002] There has been cupping therapy that uses the principle of negative pressure for treatment since ancient times, and its curative effect is unquestionable. It has experienced and benefited countless people. However, almost always use this traditional cupping method and shape of the cup. There are some small improvements in the method of generating negative pressure, and this traditional cupping has obvious limitations, that is, it can only improve the microcirculation by expanding capillaries in a small part of the treatment area where the human muscles are relatively flat and thick. The joints or the entire limbs cannot be treated with negativ...

Problems solved by technology

[0002] There has been cupping therapy using the principle of negative pressure in my country since ancient times. Its curative effect is undoubted. There are countless people who have experienced it and benefited from it. There are some small improvements in the method of generating negative pressure, but the limitation of this traditional cupping is very obvious, that is, it can only improve a little microcirculation by dilating capillaries in a small part of the treatment area that is relatively flat and thick in human muscles. The joints or whole limbs cannot be treated with negative pressure. At the same time, because there is no standard for traditional cupping techniques, the control of negative pressure value is very random, resulting in various treatment accidents.

[0003] There are many research inventors trying to improve the traditional cupping technology, which produced many beneficial improvements or attempts, but failed due to various reasons and design defects, such as the invention with the application number 201110113307.9, such as the China-Japan Friendship Hospital The application number is 96218196.X and the publication number CN 2096354U and other inventions all adopt the method of integral treatment cavity, which is fundamentally inconvenient for patients to use, bulky and not portable. There have been similar overall treatment cavity in foreign countries and adopt the airbag sealing method China has introduced this type of equipment from the Netherlands before, but it was abandoned because of its extremely inconvenient use and severe radial compression of blood vessels caused by improper sealing methods. Although it has been clinically proven that its therapeutic effect is obvious

The inventor once went to the Fourth Military Medical University in my country where there was the earliest substantial research and a large number of clinical trials on this equipment, consulted relevant experts who participated in the research, gained professional experience, and knew the sealing defects of this type of imported equipment. Northwest Medical Devices Factory has applied for the improved sealing method with the application number 93203034.3, but because the defect of the imported equipment is not only the sealing problem but also the friction problem, and the improved sealing method is still very inconvenient to operate, so it can only be abandoned. A device with very effective clinical effects has not benefited the general public so far

[0004] The inventor believes that the large-scale popularization and application of a physical therapy instrument or any treatment machine must first allow the common people to use it conveniently and reliably. All the above attempts in the prior art have the side effects of cumbersome operation, heavy equipment and complicated sealing at the same time Quite obviously, for all the defects of the above products and inventions, the inventor, after careful research and repeated practice, found a method that is quite easy to operate and very reliable. The weight of the whole product including the control parts can be controlled at about 1 kg.

Traditional methods such as airbag sealing in the prior art will inevitably lead to inconvenient access to the treatment chamber for limbs, and the convenience of entering and exiting the equipment will directly affect the success of the product

The so-called rainbow sealing method adopted by the German negative pressure equipment Vacusport, the inventor has personally experienced it, is not suitable for high negative pressure situations, cannot really work for a long time, and is very complicated and poor in sealing effect

[0005] The invention of 201110113307.9, which was granted an invention patent, intends to solve the problem of difficulty in getting in and out of the limbs by changing the shape of the opening, but after a simple observation of this invention, it can be found that it does not solve the full-closed compression of the limbs by the variable diameter ring at all. When the negative pressure is applied, the variable-diameter ring compresses the blood vessels and prevents the flow of blood and lymph tissue fluid to the negative pressure area, which greatly reduces the therapeutic effect. There is no improvement in the cross-infection of limbs, so even if it is granted an invention patent, it cannot be actually produced due to its own technical defects.

[0006] Furthermore, since all current negative pressure therapy equipment adopts a straight cylindrical treatment chamber, according to physical principles, under the action of negative pressure, the human body and the treatment chamber will have a pressure imbalance due to the pressure difference between the inside and outside, and there will be a mutual relationship between them. Because of this unbalanced pressure, there will be a tendency for relative movement. When the negative pressure reaches a certain value such as -13Kpa, when the cross-sectional area of ​​the leg of an ordinary person is 150 square centimeters, if the leg is completely inside the treatment chamber, this The pressure difference between the inside and outside will reach about 20KG. Such a large pressure is enough to cause the treatment chamber to move. If the weight of the treatment chamber is increased and the friction with the ground is used to fix the treatment chamber, then the treatment chamber that can generate 20KG friction The weight must not be light, otherwise it will cause the relative movement of the seal, lose the seal and have no therapeutic significance

Existing foreign equipment is almost cumbersome up to about 50KG, not portable at all, and the side effects of sealing sleeves or airbags cannot be widely promoted

Professor Tong Xiaolin, the chief medical expert of the famous 973 project in China, had three consecutive patent application numbers of 96204856.9, 96218473.X and 96218196.X when he was working in the China-Japan Friendship Hospital, trying to solve the above-mentioned problems of the straight type, but because it failed from Considering the principle of structural mechanics, but using a complicated method, coupled with the simultaneous use of the overall cavity and sealing sleeve seal, so the invention can not be implemented and invalidated
