FR2931658A1 - COMPRESSION AND CONTAINMENT ARTICLES WITH COOLING ZONES - Google Patents

Abstract

The compression and / or compression article of the type comprising refrigerating means is remarkable in that it is designed with one or more manufactured zones (1) having a textile structure with at least mesh threads (2) and and / or weft and supply leads (3) constituting loops (3a), and in that one of these son or more of them of the same function have refrigerating properties.

Description

The invention relates to the technical sector of stockings, socks and compression sleeves, of recovery, to compression and / or compression bandages and bandages, for medical and therapeutic purposes. BACKGROUND OF THE INVENTION

In known manner, it is considered that the application of a cold effect on certain areas of the limbs or bodies of an individual may be of therapeutic interest. This application is performed on wounds, or in some places with inflammations or edema. In a very empirical way, pieces of wrapped ice are deposited, but only for very short periods of time requiring immobilization of the individual.

Various studies, publications and patents have referred to this type of treatment using more or less sophisticated means. For example, the US 2003/0135171 patent teaches the realization of a double wall tubular compression banding integrating them with therapeutic agents to deliver cold, these agents may be in the form of cooling capsules for example.

Patent WO 02/02181 also discloses a restraining device containing a cooling fluid. US Patent 5991660 also proposes dressings with cooling device.

The concept of cooling textile yarns intended to be integrated into textiles for clothing purposes is also known.

The Applicant's approach was to make a new compression article and / or contention with cooling zones which increases very significantly the quality and comfort to wear by the individual of the article considered avoiding temperature differences in the cutaneous level. Another object sought after according to the invention was that the cooling / cooling effect is intended to reduce the skin temperature locally or in an extended manner by means of a compression and / or compression effect. According to a first characteristic of the invention, the compression and / or compression article of the type comprising refrigerating means is remarkable in that it is designed with one or more fabricated zones having a textile structure with at least mesh and / or weft yarns and constituent threads of loops, and in that one or more of these yarns of the same function have cooling properties.

These and other characteristics will be apparent from the rest of the description. For fixing the object of the invention illustrated in a nonlimiting manner to the figures of the drawings in which: FIG. 1 is a schematic view, by way of example, of a stocking sock or sock produced according to FIG. invention. FIG. 2 is a schematic view of another exemplary embodiment and implementation of the invention in the form of a compression and / or compression sleeve. FIG. 3 is another variant of FIG. a compression bandage and / or compression arranged according to the invention. FIG. 4 is a diagram illustrating the textile structure of the article according to the invention. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

The article of compression and / or contention is referenced by (A) and is defined by a textile structure in different configurations of socks, socks, sleeves, bandages.

This article comprises all or part of its surface one or zones made (1) specifically to the invention to ensure combined effects of compression and / or contention and cold. FIGS. 1, 2 and 3 show examples of the positioning of these zones at specific places such as the calf, the foot or the like.

For this purpose, according to the invention, the zone or zones are made with at least in combination of the mesh threads (2) and the input threads (3) constituting loops (3a) making it possible to produce a tight structure, thick for the configuration of the loops and soft to the touch. According to the invention, one of the son or son of the same function have refrigerating properties. The loop structure makes it possible to increase the specific surface area of exchanges and the quantity of refrigerant material, and thus to increase the efficiency of the device. In a first implementation, the refrigerant wires are the constituent input wires. loops and are likely to come in contact with the skin of the individual. The refrigerant son can also be the constituent son of the mesh.

The loop portion may appear on the outside of the article without cooling properties to increase the duration of the cooling effect, and this, thanks to the insulating cushion effect due to the air present inside the contexture . The loop portion is nevertheless generally on the inside of the article.

Different types of complementary threads can be introduced, vanished son or weft son for example. If the article has a weft thread, the refrigerant thread may be on the weft and / or on the mesh.

The textile structure is obtained by knitting or weaving in a conventional manner, the son may be elastic or not, textured or not, gimped or not. The importance of the loops (density, height) is defined according to the needs and applications of the article of compression and / or contention.

Yarns having refrigerant properties can be processed directly to include these properties or to receive microcapsules themselves integrated or grafted onto the yarn.

Some known yarns having these properties are marketed under the brands OUTLAST, CLIMA, SMARTSEL, LUXI-COOL, LUXILON. The invention is thus remarkable for the combination obtained by the compression and / or compression article with its effects, the cooling capacity of some of its threads and the mesh-loop structure which makes it possible to define very tight textured zones with a homogeneous application, comfortable at the place of application. Due to this particular structure and the combined effects of compression and / or compression and cold, a reduction in cutaneous temperature and vasoconstriction is obtained. The compression and / or compression article according to the invention is used in the context of: - medical treatment, venous disease, treatment of wounds (ulcers, bedsores); - recovery and care after exercise by its action in the circulatory system, muscles and tendons.

The zone (1) with refrigerant capacity is made on all or part of the surface of the article, in all geometric configurations, depending on the applications and needs. The same article may include several refrigerating zones as shown in FIG.
