Description

The useful model belongs to medicine, to physiotherapeutic devices made in the form of a needle applicator, intended for physiotherapeutic effects on reflexogenic zones of the human body, can be used for therapeutic and preventive purposes both in medical institutions and in domestic conditions.

Widely known applicators, which include an elastic base of the applicator and needles fixed in the base of the applicator with the possibility of the tips of the needles protruding beyond the base of the applicator to form the working side of the applicator. The bases of such applicators are made in the form of an elastic sheet, usually rectangular in shape.

Thus, a known applicator containing an elastic base of the applicator, needles fixed in the base of the applicator with the possibility of the tips of the needles protruding beyond the base of the applicator to form the working side of the applicator. The base of the applicator is made in the form of an elastic rectangular sheet. The needles are made in the form of rods (nails) with a pointed end and a head on the opposite end, as a means of fixing the needle in the base of the applicator. The needles are made of materials (metals) with different electrochemical potentials. Needles can be made with metal coatings (with exposed needle tips), the electrochemical potential of which differs from the electrochemical potential of the needle material. With the specified execution of the needles, between the needles and their coatings in the area of contact of the needles with the user's skin, galvanic microcurrents occur, which cause the effect of galvanization of the skin, as well as electrophoresis, the result of which is the transfer of trace elements (materials of the needles and their coatings) into the user's body (patent of Ukraine for useful model Mo 53553, IPC AbIN 39/08, application date 04/13/2010).

Common features of the analogue and the proposed solution are: an applicator for reflexology, containing the base of the applicator, needles fixed in the base of the applicator with the possibility of the tips of the needles protruding beyond the base of the applicator to form the working side of the applicator.

The applicator is not suitable for folding into a compact form, therefore, given its large size, it is inconvenient for compact packaging, shipping, and storage.

The closest analogue is an applicator for reflexology, which is known under a Russian patent

Federation VO2195917, IPC AbIN 39/08, priority date 07/15/1999 (also published:

The applicator contains the base of the applicator with individual needles fixed in it as elements of reflex action. The tips of the needles protrude beyond the base, forming the working side of the applicator. The base of the applicator is made in the form of an elastic rectangular sheet.

Each needle is made in the form of a rod, one end of which is pointed (needle point), and the other end has a head (thickening), which is a means of fixing the needle in the base of the applicator. The needles are made with at least a single-layer coating with the formation of zones near the tip of the needles made of at least two materials with different electrochemical potentials. There may be different options for performing coatings. The coating can be applied to the base of the needle with the needle tip exposed, or applied to the needle tip with the needle base exposed, or can be made of multiple layers of different materials with the needle tip exposed and each coating layer near the tip. The bases and coatings of the needles can be made of metals selected from the group consisting of: steel, copper, chromium, nickel, silver, cobalt, aluminum, magnesium, zinc, tin, titanium, vanadium, beryllium, gold, platinum, palladium, strontium, tellurium , as well as their alloys and oxides. The needles located next to each other are made of different materials. With this execution of the needles in the epidermis of the user's skin, galvanic microcurrents occur, flowing between the needles, as well as between the bases of individual needles and their coatings, the result of which is the well-known skin galvanization effect.

In addition, as a result of electrophoresis, many trace elements are transferred to the user's body. These phenomena enhance the therapeutic effect of the applicator.

Common features of the closest analogue and the proposed useful model are: an applicator for reflexology, containing the base of the applicator, needles fixed in the base of the applicator with the possibility of the tips of the needles protruding beyond the base of the applicator to form the working side of the applicator.

A number of needle applicators have significant sizes, for example, the Lyapko "Kilymok" applicator

The large 7.0Ad" has dimensions of 275 x 480 mm, the dimensions of the Lyapko "UALP Quadro 6.2Ad" applicator are 117 x 471 mm. It is desirable that such applicators have the possibility of being converted into a more compact form, for example by folding. The applicator selected as a prototype , like the analogue given above, is not suitable for folding into a compact form (damage to the base of the applicator is possible in the bends), therefore, with its large size, the applicator cannot be compactly packed, because it is inconvenient for sending, storing (inconveniences in operation).

In addition, this implementation of the applicator does not allow creating spatial forms of the applicator, which limits its functionality.

The basis of the useful model is the task of increasing the ease of use of the applicator due to the possibility of folding it into a compact form and expanding the functional properties of the applicator due to the possibility of creating applicators with different spatial configurations.

The task is solved by the fact that the applicator for reflexology, containing the base of the applicator, needles fixed in the base of the applicator with the possibility of the tips of the needles protruding beyond the base of the applicator to form the working side of the applicator, according to a useful model, is made in the form of serially connected sections , while at least part of the perimeter of the base of each section has fastening elements, which are made with the possibility of flexible or hinged connection of sections or connection of the sides of one section. Fastening elements are made integral with the base of the section and/or in the form of separate parts fixed on the base of the section.

Part or all of the fastening elements are made in the form of lugs and the axis of rotation, which is located in the holes of the lugs. Part or all of the fastening elements are made in the form of at least a single-layer flexible strip. At least one of the layers of the flexible strip is made as a reinforcing layer. Part or all of the fasteners are made in the form of a spiral threaded through holes in the base of the section.

The specified features are essential features of a useful model, as they are necessary and sufficient in their entirety to achieve the technical result - the possibility of folding the applicator into a compact form and expanding the functional properties of the applicator.

The implementation of the applicator in the form of sequentially connected sections, the implementation of at least part of the perimeter of the base of each section with fastening elements made with the possibility of flexible or hinged connection of sections or the connection of opposite sides of one section, provides the possibility of folding the applicator into a compact form by turning the adjacent sections at their junctions. In the folded state of the applicator, the sections are arranged in parallel layers. The minimum dimensions of the applicator in the folded state are determined by the dimensions of the individual section. For example, when performing the Lyapko "UALP Quadro 6.2Ad" applicator (dimensions 117 x 471 mm) in the form of four sequentially connected sections with the specified elements of its fastening

The overall dimensions when folded into four layers will be 117 x 120 mm. The specified implementation of the applicator also allows you to connect sections to each other or to connect opposite sides of one section to form a spatial configuration of the applicator, which expands the functionality of the applicator.

Fastening elements can be made integral with the base of the section and/or in the form of separate parts fixed on the base of the section.

Part or all of the fastening elements can be made in the form of lugs and the axis of rotation, which is located in the holes of the lugs.

Part or all of the fastening elements can be made in the form of at least a single-layer flexible strip. At the same time, at least one of the layers of the flexible strip is made as a reinforcing layer.

Part or all of the fastening elements can be made in the form of a spiral drawn through the holes in the base of the section.
