Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of an air pine surge treatment device that obtains a pine surge treatment effect by supplying and exhausting air into an airtight bag.

[Conventional technology]

Conventionally, an airtight bag made of flexible material such as rubber is wrapped around a part of the body, such as a hand or foot, and compressed air is pumped into the bag to compress or release blood vessels in the affected area. A structure has been proposed that has the effect of promoting the circulation of blood (mainly venous blood and lymph fluid) and obtaining a pine surge effect.

However, in situations where the muscles in the affected area are tense and stiff, and the flow of blood and lymph fluid is extremely poor, simply compressing and releasing the affected area can provide instant pleasure, but the sufficient effect of pine surgery may not be sufficient. cannot be obtained. For this reason, conventionally, it has been proposed to define an airtight bag into three or more air chambers, and sequentially supply and exhaust air to each air chamber, thereby sequentially moving the compression and release positions for the affected blood vessels. In order to do this automatically, a plurality of solenoid valves are used corresponding to the supply and exhaust ports that communicate with three or more air chambers, and these solenoid valves are controlled to open and close by a relay control circuit. A rotary switching valve mechanism has been proposed that can control three or more air supply and exhaust ports so that a single air supply and exhaust port communicates with the air supply means.

[The problem that the idea attempts to solve]

However, conventional switching valve mechanisms that use electromagnetic valves have the disadvantage that not only the control circuit is complicated, but also the manufacturing cost is significantly increased due to the use of a large number of electromagnetic valves. In addition, although a single switching valve mechanism has the advantage of being extremely simple in configuration, it also requires air supply and exhaust operations to be performed at a constant cycle for three or more air supply and exhaust ports. Although it is effective when performing air pine surge by enclosing the entire upper and lower limbs with an airtight bag, it is especially effective for air pine surges in very limited areas of the body, such as knee joints, elbow joints, and ankle joints. When performing intensive pine surge treatment, there is a problem in that a sufficient pine surge effect cannot be obtained because air supply and exhaust cannot be performed alternately and continuously to the local area. In this case,
In order to selectively supply and exhaust only required air chambers among a large number of air chambers, the configuration must be further complicated.

Therefore, the purpose of this invention is to provide an airtight bag body with two air chambers arranged adjacently so as to be suitable for local parts of the body, and to provide highly variable supply and exhaust operations for each air supply and exhaust port of this airtight bag body. To provide an air pine surge treatment device configured to perform.

[Effect of idea]

As is clear from the above-mentioned embodiments, according to the present invention, by employing the valve mechanism having the above-mentioned configuration, the bag body consisting of two air chambers can be alternately and smoothly supplied and exhausted. It is possible to perform intensive air pine surge treatment on local parts of the body.

Therefore, when the air pine surge treatment device configured in this way is used for treating joints, for example, the two air chambers alternately perform supply and exhaust operations to treat the joints. Using air pressure, the joint is strongly tightened and released, and then tightened and released again repeatedly, which promotes blood circulation within the joint, increases metabolism within the joint, and stimulates synovial fluid secretion. It also makes the synovial membrane smoother and can greatly improve joint mobility. In addition, by applying the pneumatic pine surge treatment device of the present invention to joints, if there is adhesions or contractures in the surrounding muscles, tendons, and ligaments, these can be removed and relaxed, and pathological exudation can be further prevented. If there are objects in or around the joints, it is possible to intensively crush them in a short period of time to promote absorption and restore health quickly. Incidentally, examples of application of the pneumatic pine surge treatment device according to the present invention to joints are shown in FIGS. 8 to 10.

Therefore, the pneumatic pine surge treatment device of the present invention uses a valve mechanism that has a simple configuration and can be manufactured at low cost to easily and quickly perform pulsating pine surge treatment using pneumatic pressure on all diseased parts of the body. It can be achieved intensively, and its practical effects are extremely large.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various design changes can be made within the scope of the spirit of the present invention. .
