Description

The present invention relates to a cuff for use in thermotherapy treatments and a system with such a cuff.

Thermotherapeutic treatment is a medical treatment that has been known for a long time, in which heat is supplied to the body - this is referred to as heat therapy - or heat is withdrawn from the body - in this case one speaks of cold therapy. In order to be able to transfer heat to the body during heat therapy, heat transfer from a heat source to the body is required. With cold therapy, however, the heat must be removed from the body, i.e. H. heat from the body has to be transferred to a heat sink.

The heat transfer can be done directly in both cases, i.e. H. by bringing the body itself into contact with a heat transfer medium, e.g. B. in a sauna or in a cold water bath. In addition, indirect heat transfer is possible, in which the body does not come into contact with a heat transfer medium. The present invention is concerned with the latter procedure.

Indirect heat transfer uses a heat transfer medium that can be gaseous or liquid, but also solid, depending on the application. Water, in particular distilled water, is particularly preferred as the heat transfer medium. In addition, a gas or a gas mixture and here in particular air or an oil or an oil mixture or other suitable liquids or liquid mixtures can also be used.

The process of heat transfer can be discontinuous or continuous. A known discontinuous heat transfer application is the so-called ice pack. For this, water is frozen to ice and poured into a suitable flexible, usually watertight, sealable cover. The ice pack is placed on the respective body part and withdraws heat from the body until the ice has thawed and the temperature of the ice pack has approached the body temperature.

In the continuous process, the heat-transfer medium is supplied to a heat transfer body at a temperature which, depending on the application, is above or below the body temperature and is in contact with the affected part of the body.

The present invention has for its object to provide a cuff with at least one heat transfer body and a system with such a cuff, the heat transfer body, depending on the design, is suitable for continuous, discontinuous or both therapy forms.

This object is achieved by the subject matter of claim 1. Preferred developments of the invention are the subject of the dependent claims.

The system according to the invention is the subject of claim 14.

The invention provides a cuff for use in the heat therapy treatment of a human foot, particularly for use in the treatment of tissue damage after surgery, injury, inflammation and chronic rheumatic disease, and particularly in chemotherapy with cytostatic drugs palmar-plantar erythrodysesthesia (PPE), such as Carboplatin, capecitabine, 5-fu, cyclophosphamide, cytarabine, docetaxel, doxorubicin, oxaliplatin, paclitaxel, sorafinide and sunitinib, with a heat transfer body which can be brought into an essentially flat starting form and has at least a first flexible material layer and at least a second flexible material layer which delimit one or more flow spaces through which a heat transfer fluid flows and which are connected to one another by a plurality of contacting devices, and with at least a first feed line for supplying a heat transfer fluid to the heat transfer body and at least a second feed line for a heat transfer fluid from the heat transfer body dissipate.

The top view of the heat transfer body is asymmetrical in design and has a first section which essentially corresponds to the outline of the sole of the foot, and a second section which is preferably integrally connected therewith and which is designed such that it extends over the position in the use position A user's forefoot area extends to.

The contacting devices can preferably be subjected to tension and / or pressure.

Furthermore, a connection device is provided, by means of which this first section is held at the foot of the user with this second section in the use position. This ensures that the The cuff lies flat against the user's foot and thus good heat transfer is guaranteed.

A flow space is understood to mean a continuous space in which the heat-transfer fluid can flow from one of the points to the other point for any two points inside the space.

The cuff can be provided for single or multiple use.

• - die Form einer den Fuß umschließenden Hülle ohne Unterteilungen des Innenraums;
• - die Form eines Schuhes oder Strumpfes, welcher lediglich den Vorderfuß und die Fußsohle umschließt und/oder bedeckt.

In a preferred embodiment of the invention, the heat transfer body has one of the following forms or can take one of these forms:

• - the shape of an envelope enclosing the foot without dividing the interior;
• - The shape of a shoe or stocking, which only encloses and / or covers the forefoot and the sole of the foot.

The contacting devices which connect the first and the second flexible material layer are distributed, in particular, at small and regular intervals on the inner surface of the first flexible material layer and the inner surface of the second flexible material layer and serve, in particular, to close the flow spaces by the first being lying flat on top of one another to prevent flexible material layer and the second flexible material layer. The contacting devices are preferably designed as welding points with which the first flexible material layer is welded to the second flexible material layer and is thereby connected.

In a preferred embodiment of the invention, the plurality of contacting devices is arranged at least partially in a grid-like manner, preferably at the corner points of imaginary rectangles, further preferably at the corner points of imaginary squares.

Such a grid facilitates the design of the heat transfer body and ensures that the flow spaces between the first flexible material layer and the second flexible material layer or parts thereof are evenly prevented from being closed.

In a preferred variant of this embodiment of the invention, the at least one first flexible material layer and the at least one second flexible material layer are connected linearly, in particular in a straight line, between at least two contacting devices, in particular between the centers of the two contacting devices.

Such line-shaped contacts can preferably be produced in a particularly simple and reliable manner by welding the first flexible material layer to the second flexible material layer as weld seams and then no longer require any further, separate elements for delimiting the flow spaces.

Such an “overlapping” arrangement of the line-shaped contacts for delimiting the flow spaces and the contacting devices is advantageous, since otherwise contacting devices could come very close to the line-shaped contacts and the flowable width of the flow chamber would be unnecessarily severely restricted at this point. In addition, the line-shaped contacts themselves prevent the flow spaces from being closed, so that an immediately adjacent arrangement of line-shaped contacts and contacting devices is unnecessary.

Furthermore, the “superimposed” arrangement of line-shaped contacts and contacting devices - especially when the latter are arranged in a grid - results in a clear and visually appealing course of the flow spaces.

In a preferred variant of this embodiment, at least one of the linear contacts has at least one rectilinear section. The linear contacts preferably consist of more than 50% of their total length, more preferably more than 90% of their total length, of straight-line sections.

As a result, the tools for producing the heat transfer body, in particular tool parts for pressing and welding the first flexible material layer and the second flexible material layer to one another along the linear contacts, are easier to produce. In this case, too, there is a clear and visually appealing course of the flow spaces.

In a further preferred embodiment of the invention, the plan view of the heat transfer body is asymmetrical in design and has a first section which essentially corresponds to the outline of the sole of the foot and a second section which is preferably integrally connected thereto and which is designed such that it extends over the forefoot area of a user in the use position.

The heat transfer body is preferably collapsible, which makes it easier to manufacture, and in particular has the shape of a flat surface in which the first flexible material layer and the second flexible material layer are connected to one another. Furthermore, the two flexible material layers in particular are easier to clean and / or disinfect in the flat initial shape of the heat transfer body than in the use position.

In a preferred variant of this embodiment, the heat transfer body has a fold-like transition area. A fold-like transition area is understood here to mean an area of the heat transfer body in which the first flexible material layer and the second flexible material layer in cross-section have a bend with a small radius when the heat transfer body is in the use position.

The fact that a flow space extends over the fold-like transition area has the advantage that the entire heat transfer body can then be realized with only one continuous flow space and thus also only a first feed line and a second feed line, which also need not have branches to different flow spaces, are necessary.

A plurality of flow spaces or a plurality of sections of the same flow space preferably extend over the fold-like transition region.

Preferably, a plurality of sections of the same flow space extending over the fold-like transition area are connected on one or both sides of the fold-like transition area by a section of this flow space, each of which essentially runs along the fold-like transition area.

At least one contacting device is preferably arranged on the fold-like transition area within a flow space, which extends over the fold-like transition area.

In a further preferred embodiment, the flow space is interrupted at at least one point of a linear contact, in particular in the area of the fold-like transition region, so that the fluid can flow between two flow spaces in order to ensure an uninterrupted flow of the fluid.

In a further preferred embodiment, in the case of flow spaces, in particular in critical flow spaces, in which a fold is formed in the flow space, in particular as a result of kinking and / or rotating movements of the human foot, the fluid flows at at least one interrupted point in a linear contact between two flow spaces can to ensure an uninterrupted flow of the fluid.

In a further preferred embodiment, at least one parallel guidance of the fluid in at least two flow spaces is possible at a predetermined angle, in particular perpendicular or parallel to the fold, in order to ensure an uninterrupted flow of the fluid.

The total width of a flow space extending over the fold-like transition area measured along the fold-like transition area is preferably greater than, in particular at least twice as large as the total width of this flow space measured perpendicular to the flow direction in a section arranged immediately before or after the fold-like transition area as seen in the flow direction this flow space.

The measures mentioned serve - individually or in combination - to specifically increase the cross-sectional area of the flow space or spaces extending over the fold-like transition area in order to reduce the height of the flow spaces, which can be caused by the folding of the heat transfer body along the fold-like transition area to counteract. Such a reduction in the height of the flow spaces could reduce the amount of heat-transferring fluid that can flow through the flow spaces per unit of time, and thus also the heat transfer itself.

In a further preferred embodiment of the invention, the second section is asymmetrical in comparison to the first section and in particular trapezoidal with straight and / or continuously curved side edges.

According to the invention, a connecting device is provided, by means of which the first section can be connected to the second section or is connected in such a way that the cuff is held at the foot of the user in the use position.

In a preferred embodiment of the invention, the connection device is detachable.

The connecting device preferably has at least one fixing element, in particular at least one push button and / or a Velcro fastener and / or a loop for binding and / or an elastic band, in order to releasably connect the first section to the second section in the use position.

As a result, the heat transfer body can be repeatedly opened, cleaned and / or disinfected and then closed again, as a result of which the period of usability of the cuff can be extended.

However, it is also possible that at least two sections of the heat transfer body are permanently connected to one another, for example by welding. This increases the stability of the cuff and the thermal insulation of the body part to be treated from the environment.

In a preferred variant of this embodiment, the at least two sections of the heat transfer body can be releasably connected to one another in different ways, so that different sizes of the heat transfer body arise, which correspond in particular to different sizes of the body part to be treated.

It is preferably possible for the connecting device to have a plurality of fixing elements, which are in particular arranged offset to one another, in order to enable variable size adaptation to the foot. This results in a simplification in the manufacture, storage and distribution of the cuff as a commercial product, since the product then only has to be manufactured, held in stock and delivered in a few or even in one version without the patient's body dimensions, in particular, their different foot sizes must be taken into account ("one size fits all").

Furthermore, it is preferably possible for the connecting device to be designed in such a way that it at least partially encompasses the cuff in the use position and, in this encompassing position, exerts auxiliary forces on the cuff that at least partially contribute to holding the cuff in the use position.

The connection of the at least two sections of the heat transfer body to one another preferably takes place in the use position of the heat transfer body.

In a further preferred embodiment, the first feed line and the second feed line are connected to the heat transfer body essentially parallel to one another. It is advantageous here that the two feed lines can be routed together from and to the user and that they can be handled easily.

In a further preferred embodiment, the first feed line and the second feed line are arranged in the region of the inner instep or the outer instep of a user's foot on the heat transfer body when the sleeve is held on the user's foot in the use position.

In this way, it can be achieved that the flow of the fluid within the flow spaces of the heat transfer body is essentially maintained when a user of the cuff moves during use of the cuff.

In particular, when walking, for example, pressure is exerted on the cuff in the area of the heel by the weight of the user, as a result of which the fluid flow between two flow spaces can be at least partially reduced. A kink caused by bending the user's foot while walking in the area of the heel can cause an interrupted fluid communication between two flow spaces. This is essentially prevented by the arrangement of the first and second feed lines in the area of the inner instep or the outer instep.

The outer instep of a foot in the sense of the invention represents the outer side of a first foot of a user of the cuff, which, relative to the normal, substantially parallel position of the two feet when standing, is directed away from the second foot of the user.

The inner instep of a foot in the sense of the invention represents the inner side of a first foot of a user of the cuff, which, relative to the normal, substantially parallel position of the two feet when standing, is directed towards the second foot of the user.

However, the first feed line and the second feed line can also be arranged in the region of the heel of a user's foot on the heat transfer body when the sleeve is held on the user's foot in the use position, that is to say at the rear end of the heat transfer body in its use position.

In a further preferred embodiment, the sleeve has at least one thermal insulation device which at least partially covers the heat transfer body.

On the one hand, this can make it possible for at least some of the heat transfer of the heat-transferring fluid to the environment to be reduced. Furthermore, an accumulation of water on the cuff can be at least partially reduced, which forms in particular due to surface condensation on the cuff, since the cuff generally has a different temperature than the ambient air due to the heat-transferring fluid.

Furthermore, the thermal insulation device can be adapted in such a way that aesthetic aspects in particular are additionally taken into account. For example, the thermal insulation device can be designed in a specific color, preferably blue, or in a specific color pattern.

A heat treatment system according to the invention for use in the heat therapeutic treatment of a part of the human body has a cuff according to the invention and a fluid supply device which can be connected in a fluid-conducting manner to the at least one first supply line and the at least one second supply line of the cuff and which is set up to transmit a heat-transferring fluid to a temperature suitable for the heat treatment, preferably a temperature between +5 ° C and +35 ° C, more preferably between +10 ° C and +20 ° C, particularly preferably between +10 ° C and +12 ° C and very particularly preferably to be tempered by approx. +10 ° C., to supply the heat-transferring fluid tempered in this way to the heat transfer body of the sleeve via the first feed line and to remove the heat transfer fluid from the heat transfer body via the second feed line.

The use of the cuff and / or the heat treatment system can also be used for the cosmetic treatment of the skin of the human foot. These include applications with regard to the treatment of wrinkles or the reduction of wrinkles, the thermal influence on the capillary drawing on the skin and / or the non-therapeutic reduction of skin swellings.

In addition, the cuff and / or the heat treatment system can be used to thermally reduce the formation of free radicals on the skin surface.

Further advantageous embodiments of the invention are explained in the following description in conjunction with the accompanying drawings. Show:

• 1 : a cuff according to the invention in the shape of a shoe in the initial form and
• 2nd : Another embodiment of a boot-shaped cuff in the original form.

1 shows a cuff according to the invention with a heat transfer body 1 in the initial form, creating the first section 1a and the second section 1b which is asymmetrical compared to the first section 1a is arranged, the heat transfer body 1 are visible. The sleeve also has a first feed line 2nd and a second supply line 3rd through which a heat-conducting, tempered fluid, in particular heated or cooled water, can be supplied or removed by a fluid supply device (not shown).

The heat transfer body 1 can be along a fold-like transition area 9 fold up and in the use position takes the form of a shoe, in particular a shoe that is only closed in the area of the forefoot (ie a “slipper”).

The heat transfer body 1 has a first flexible material layer and a second flexible material layer, which are arranged congruently and of which in the supervision in 1 only the inside of the first flexible material layer is visible. The two layers of material are preferably made of plastic. In the embodiment according to 1 the two layers of material are largely transparent.

At their outer edges, the two layers of material are sealed by an edge weld 8th , which almost completely around the entire heat transfer body 1 runs around, welded together in a fluid-tight manner.

The edge weld 8th is only at the implementation points of a first supply line 2nd and a second supply line 3rd interrupted where it can be greatly widened around the ends of the first and second feed lines 2nd , 3rd to hold securely and to seal fluid-tight. The implementation points of the first and second supply lines 2nd , 3rd are in the range of 1 lower end of the heat transfer body 1 arranged on the open side of the shoe (corresponding to the heel). Furthermore, the supply lines 2nd , 3rd preferably arranged parallel to each other.

On the edge weld 8th are button halves at certain, sometimes equidistant intervals 10a , 10b attached to the first half 1 a of the heat transfer body 1 the plug-like and in the second half 1b the socket-like halves or vice versa. After collapsing the heat transfer body 1 one push button half each 10a in a push button half 10b or vice versa. This takes the heat transfer body 1 the position of use and thus the shape of a shoe in which the patient can put his foot in order to apply heat therapy.

The plug-like and / or the socket-like button halves could also be used 10a , 10b offset, in particular in several rows, so that the button halves 10a , 10b can snap into each other in different ways and thereby the heat transfer body 1 result in different shoe sizes.

The first and second layers of material are on their entire surface, apart from the edge weld 8th , through a variety of welding spots 5 connected together, which are arranged in a square grid. The distance between adjacent welding points in the horizontal or vertical direction is referred to below as the "grid spacing r".

A plurality of channel walls is provided by further weld seams in the interior of the surface of the first and second material layers, by means of which the first and second material layers are connected to one another in a fluid-tight manner 6 educated. The canal walls 6 consist for the most part of contiguous, straight sections. In particular, connect the channel walls 6 each have a number of adjacent welding spots with one another.

Through the canal walls 6 is in the heat transfer body 1 a single, continuous, fluid-conducting channel between the first and the second material layer 4th educated.

The channel 4th starts in the first half 1a of the heat transfer body 1 at the end of the first supply line 2nd and is through the section 4a described, which has a width of about 5 r. This first section 4a , which tempers the rear left part of the sole of the foot, leads the fluid to the fold-like transition area 9 where the section 4b is significantly increased in width. At the widest point, the section points 4b a width of 16 r, measured transversely to the direction of flow within the channel 4th . This counteracts a reduction in the height of the flow spaces, which can be caused by the collapsing of the heat transfer body along the fold-like transition region.

Furthermore, the fluid can on a patchy channel wall 7 from section 4b to section 4e stream. This can occur in the fold-like transition area 9 in the use position, in which the fluid flow may be greatly reduced or interrupted, positively influence the fluid flow, so that a permanent circulation of the fluid is ensured.

Through diagonally arranged channel walls 6 the fluid continues across the two sections 4c and 4d passed, which temper the top of the forefoot, and enters section 4e , which is also in the area of the fold-like transition area. This section is like section 4b through a much wider flow channel 4th characterized, which has a width of 12 r at the widest point, measured transversely to the flow direction within the channel 4th .

Then the channel goes 4th over the section 4f , which is arranged under the toes of the foot, in the sections 4g , 4h such as 4i about. These sections, which have an average width of 8 r, are arranged in the area of the sole of the forefoot. Furthermore, in the sections 4g , 4h such as 4i Canal walls 6 formed transversely to the fluid flow in order to influence the fluid flow in the circulation. These canal walls 6 are as incomplete channel walls 7 formed to the fluid flow z. B. to be able to adapt to a specific shape of the sole of the foot. In particular, due to the incomplete channel walls 7 the flow velocity of the fluid is influenced, in particular reduced.

This is followed by the section 4j which is arranged in the area of the heel of the user and the fluid to the second feed line 3rd leads to remove the fluid from the heat transfer body again.

2nd shows a further embodiment of a cuff in the shape of a shoe in the initial form. Here are the first supply line 2nd and the second lead 3rd in the area of the inner instep or the outer instep of a user's foot on the heat transfer body 1 arranged when the cuff is held in the use position on the user's foot.

Furthermore, the cuff preferably has a heat insulation device, which the heat transfer body 1 at least partially, in particular completely, covered. The thermal insulation device is preferably around the entire outer surface of the heat transfer body 1 arranged to emit an unwanted heat from the heat transfer body 1 to prevent the environment essentially.
