DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a hydraulic device for lymphatic drainage and massage of the human body.
The technical field of the invention is the field of manufacturing massage appliances that use hydraulic pressure.
One of the main applications of the invention is providing sleeves, e.g. having the shape of a limb, and suitable for putting on the limb, for the purpose of massaging it by transmitting pressure intermittently along its surface.
2. Description of the Prior Art
It has been known for a long time that massage techniques have beneficial effects on the human body for blood circulation, for eliminating fat or cellulite, for relieving pain, for reabsorbing edemas, for improving muscular performance, pleasing shapes: these techniques were originally manual, but over the last few years appliances have been developed for satisfying the increasing demand for this practice and for ensuring that treatment can be made available regularly, and over a long period of time as a replacement for the hand of the masseur, whose training is lengthy and specialized, and who can be available for only one person at a time.
Thus, four types of appliance are available, excluding those that are solely mechanical or mechanical in action, that seek to satisfy the above demand and techniques for providing good lymphatic drainage or massage, by causing variations in pressure on the skin of the human body by means of a fluid: which do indeed apply pressure that is intermittent, but they apply it in uniform manner over the entire surface to be treated: such systems are used very little since they are ineffective in practice, being far removed from the effect of a massage; which fluid is injected under intermittent pressure, which pressure is applied over the entire surface of the compartment that is in contact with the corresponding part of the body, the compartments being activated successively while pressure is caused to drop in preceding compartments so as to generate a pressure wave in the desired direction, as can be done by the hand of the masseur: in this category of system, there can be found patent applications FR 2 616 064 (Suissa), FR 2 615 397 (Frajdenrasch), FR 2 548 017 (Tissot), and FR 2 511 242 (MEGOAFEK Industrial Measuring), and many others; however the complexity of their implementation requires control to be provided by electrically-controlled valves for opening and closing compartments, and depending on the type of fluid used, either a gas or a liquid, the resulting effectiveness and reliability are often not as could be desired, due to lack of accuracy and due to local negative gradients inevitably being created, thus having a highly negative effect.
Naturally, each has its own particularities and special essential characteristics, suitable for improving effectiveness in one field or another, thereby justifying patentability, even if the same principle is applicable to all of them.
Those systems are complex and they always transmit a pressure wave of the same amplitude to all of the points of the surface to be massaged, and that does not genuinely reproduce the effect of a massage that ought to taper off from one point to another while decreasing linearly without any clearly-marked steps; found systems that do not use hydraulic or pneumatic pressure obtained by fluid circulation, but that use the static pressure of a high density fluid, essentially mercury: a rigid tank or sleeve is filled with this fluid and the limb that is submerged in it is subjected to a perfect pressure gradient which diminishes linearly from one point to another; the alternating variation of the fluid level thus produces a massage effect. In this domain we note patent requests FR 2.619.710 of Aug. 24, 1987 by Mr. P. VENDEVILLE and FR 2.639.222 of Nov. 18, 1988 by Mr. Claude J. CARTIER.
However, these systems are quite heavy to implement and often very expensive; because the pressure on the lower portion is significant, it can cause uncomfortable reactions and have medical c
