EP1529512A2 - Bath tub with foil wrap - Google Patents

Abstract

The tub is of a specific shape matching the outer contours of the human body (P) and covered with a removable plastic foil (27). After the patient (P), which can have the skin covered with a pasteous treatment, has entered the tub water is let in underneath the foil (27). The edges of the foil (27) can be slightly moistened and stuck to the rim (13) of the tub resulting in the bottom of the foil (27) floating on the incoming water. Convex massaging areas (36) can be created in the foil (27) with nozzles (33) located at the bottom of the tub. The foil (27) can be disposed of after use.

Description

The invention relates to a film tray according to the preamble of claim 1 and a method of providing such a tub.

Heat treatments, for example in the form of packages, Bathing applications or also in the form of steam bath or herbal steam bath applications, have always enjoyed great Popularity. Such applications are not just for the Improving the general well-being, but can also for health stabilization and improvement contribute.

In such heat applications, e.g. two aspects too consider.

For one thing, it is known that bathing applications, in particular in spas, spa facilities, hotels and the like certainly not negligible costs cause. Because the bathing media used already have to Hygiene reasons removed after performing an application and to carry out a next application hygienic bathing media are replaced. Should In addition, particularly effective natural products or other additives are used, so here too are usually considerable Quantities required, the cost of such To drastically increase the application.

On the other hand, however, it must also be considered that conditionally by the significantly increased life expectancy further population circles in the implementation of heat applications, especially in the elderly, a corresponding Protection of the cardiovascular system not unconsidered stay allowed. Large and overheating too much Applications can be problematic.

To the required amount of bath, for example, the amount of To reduce peloid or bath additives is according to the DE-PS 30 46 628 already an improved device for Administering Peloid Voll- or -Sitzbädern proposed been, for each bath therapy only one less part of the hitherto for reasons of hygiene only once usable bath medium is required. This was solved by an insert in the tub is provided as a liquid-tight film for separation to introduce the above and below the film Peloid bath fluid is formed. When performing Thus, a bath application can be someone in the room insert it above the liquid-separating film, see above that only the bathing liquid that comes into contact with it must be replaced for reasons of hygiene. This is compared to conventional applications that Volume of bathing liquid and bath additives, peloid etc. decrease significantly. The problem of possible overheating of the body remains.

From EP 0 144 571 B1 a device for the Administering packages became known in which the Packs only at certain positions to be overheated be positioned when performing an application being characterized by the use of insulating mats especially in the Leg and neck area of the advantage that here before especially in the elderly, overheating of one serving below a support and contact foil Heat and pressure medium can be avoided.

In both aforementioned prior art tray assemblies Thus, in each case a film is used, which is at the edge of the tub firmly clamped and held. In the Foil tray according to EP 0 144 571 B1 is administered of packs further proposed, for reasons of hygiene to use a disposable film in addition. So can in the from the above prior publication well known tub on the pressure foil first to the Places where overheating should be avoided Insulating materials are applied (for example, too in the neck, neck or head area in the form of towels or towels), and then ultimately the disposable film hang up, so in sections on the Andrückfolie lies to lie and in sections on the previously applied insulating materials. Then it lays down one person to be treated, on whose body surface the respectively desired packs or pulpy or lubricious Media can be applied. After treatment the disposable foil is thrown away.

A generic device is for example off DE 88 09 687 U1 become known. These are around a plastic insert for a sitz bath in Shape of a foil that fits snugly in the hip bath is easy to remove and after their use is without major time losses due to expensive cleaning or disinfection should occur.

In contrast, it is an object of the present invention an improved method for carrying out a heat application and an improved foil tray suitable for this purpose to accomplish.

The object is according to the invention with respect to the method according to the specified in claim 1 and / or 2 Characteristics and with respect to the film tray according to the solved in claim 9 specified features. advantageous Embodiments of the invention are in the subclaims specified.

The film tray according to the invention is characterized from that the film for the separation of the film upper space of Film subspace is used, so that, for example, in a tub of hot water from the area below the film not in the area above the Slide can get where a person to be treated into sets. Deviating from the DE 30 46 628 B1 However, this film is not known as a tub comparatively strong and thick load-bearing film, permanently clamped to the edge of the tub is, but instead consists of a comparatively thin, commercially available film that only placed on the tub and covered with a foil area hanging down the upper rim of the tub becomes. After the treatment, this disposable film can also disposed of and destroyed.

But to safely prevent water from the bottom of the film on the top of the film must now likewise over the edge of the tub covered foil at the Tub or the tub rim are attached. this happens According to the invention now solely by adhesion such that slightly moisten the film edge and then the disposable film is hung up. Moistening can easily be done by that e.g. from one administering an application Person slightly raised the foil from the tub rim, the hand immersed in the water located below the film and then the edge of the bath with a damp hand becomes (or a wet cloth etc.). Then then the film are placed. That alone gives rise very much high adhesion forces, so that such a film in the person is in the floating state above of the tub floor and can hold!

The peculiarity and the advantage of the film tray according to the invention lies not only in the fact that only a single disposable film for every bathing application used and then disposed of, but that beyond that also an individual adjustment for the Implementation of an application is possible. Because should the Foil a person to be treated not only on the back, but also the warm medium as possible from above can be supplied to the body, so can the tub rim Adhesion-holding film to the respective desired Make a slight lift and continue to let up, around a first further outward film section then fix it again on the foil edge by adhesion. Thereby, that now give more foil material in the tub can, can with appropriate fill level of the warm water in the tub now the water up rise above the top of the body, where in the corresponding Level height located below water the film has this film on the side of the body and e.g. above the thorax and / or above the abdominal or leg area covered. The warm water is here always on the opposite side of the body Foil. Thus, the body of a bather is not only in the back and side area, but also depending on Desire and need partly on the body top of Foil wrapped and replaced by warm water on the opposite Side of the film applied. This can ever as needed and given more in the upper shoulder area, in the chest area or in the abdominal area, in the area of the buttocks or in the leg area individually different be made and adapted.

But also vice versa can be a kind of "lifting" of a person carried out in a water bath by means of the film. It also has to again only the film lifted from the edge of the tub and be attracted to the outside. Subsequently, the Sheets are again laid flat on the moistened rim of the bath, to achieve the adhesion forces. Because the foil material Thus, in the tub is reduced, the film in certain areas of the body, for example in the leg area, more streamlined, reducing the corresponding body parts be raised further. This is the lie upper areas of the body then rather free and are not covered more by the foil and backed by warm water surrounded by the foil. Because this "setting" with different Altitude but only in the filled tub takes place, in which the bather, so to speak, can swim this Lifting and lowering by means of the film also take place, if the film itself is so thin that it is in itself a person due to his body weight not at all could carry and tear if trying to a person lying on the slide outside one To raise the water bath. But if the person in floats a water, body weight is reduced for example, a person of about 80 kg to less than 2 kg due to the buoyancy, so that then the film only still a load capacity of well under 10 kg, for example under 8 kg, 6 kg, 4 kg or even less than only 2 kg must take without tearing.

The foil tray according to the invention also has in particular then additional benefits if, for example, in the Pan yourself in each appropriate places (for example in the floor area, more in the side area or at the transition from the floor to the sidewall areas, etc.) one or more Water supply openings or especially water supply nozzles are arranged. The overlying preferred warmed up water (or other suitable medium) thereby generates a fluid jet, which by the invention used comparatively thin film, so to speak "unrestrained" is passed on to the body. Although So the body with the serving as a heat transfer fluid, usually warmed up water, not in contact comes, however, the generated via the nozzle effect Fluid jet effect felt in an optimal way. Will then above the film directly on the body of a treated Person-acting media, such as flowable Media, pasty media etc. added, so may even above the slide a kind of bathing application in there Liquid be carried out, the fluid jet effect over the below the foil in the tub located nozzles then virtually through the film and in the medium above the film and above the body of the person to be treated continues to act. This can be comparatively thick, usually made of rubber or similar materials existing film not be achieved, as this example, in connection with a device known from DE 30 46 628 B1 Use finds. In the above The state of the art on the one hand requires the film to be the usual one Fully absorb body weight (especially during administration of packs). In addition, the previously known Film also always reused, which only with a corresponding thick tear-resistant film can be realized. In contrast, according to the present invention, a very thin disposable film used in functional use at below the film filled water and thereby generated buoyancy forces with respect to one above the Foil person only low carrying and breaking forces must have.

Above all, however, the process according to the invention offers essential Advantages over the prior art.

Because according to the inventive method for carrying out of heat applications and in particular related with the use of a foil tray, so a tub with a slide inserted into the tub, can be a particularly favorable implementation of the heat application then realize, if at different longitudinal sections the tub the foils differently outward pulled or vice versa different towards bath interior is lowered. This allows the Querlängenmaß set the slide differently, which between the two side walls, especially the extends both side longitudinal walls of the tub. By putting on the film and thus reducing the film material or by letting the film is thus causes that over the length of the tub, the film is different deep in the tub hangs inside. This allows one in the slide lying person to be set so that different Body sections of different depths in the tub too come lie. In other words, it can be guaranteed be that, for example, the legs or the lower legs a person lying on the film by tightening the film higher lying in the tub to come as For example, the area pelvis and back, by Deterioration of the film deeper in the bathing medium immersed lie comes. Likewise, the back area in transition to the neck / head area are set higher.

Further complex measures for different height adjustment it does not need according to the invention.

Alternatively and additionally, it is further provided that the filling of the tub interior below the foil up to a final level to carry out the Application only then carried out or only after one initial filling is completed when before put a person in the slide room. With others A person can put himself on the slide, even to a time when the film is still completely relaxed in the Basin interior and above all rests on the bottom of the tub. Of the Foil edge overlaps the tub edge. Subsequently the tub can preferably be filled from below, so that by the bath medium pressure, the film then with increasing Level height from below and over the Side areas beyond the body of a lying in it Person clings and covers. The height adjustment The film can then be carried out and made later become.

In addition, it has proved to be particularly favorable that the tub circulation edge is wetted, preferably by use of the filled below the film in the tub Medium or water, then corresponding film sections on the tub edge, producing strong Holding and adhesion forces. These adhesion forces are then when performing the heat application, for example in an aqueous bath medium (in particular Water) is sufficient to remove the film or slackening in the film above the bottom of the tub floating in the medium different depths in the medium Bademedium eintauchend set, so that, for example the legs are higher than the pelvis and the lower back area.

a further cross-sectional view similar to that of Figure 4, Figure 5 or Figure 7, but at the time of getting in and out of the tub with previously emptied tub and completely lowered into the tub interior, resting on the tub surface foil.

In Figure 1 is a schematic longitudinal section and in FIG 2 in a schematic cross section along the line II-II FIG. 1 shows a trough 1, which is preferably referred to as so-called Body mold pan 1 'is formed.

The tub has a sufficient length and width on, for example, a full body or at least to be able to carry out a partial bath application.

The well formed as a so-called body mold pan 1 'comprises Furthermore, a support surface 3, which in the bottom area also a so-called lordosis survey may include 5, whereby a tub compartment 7a opposite to a longitudinal offset lying tub part space 7b is disconnected.

The pan compartment spaces 7a and 7b may be in a vertical cross-sectional view according to Figure 1, at least partially be slightly concave, thereby making a pleasant Adaptation to the back to shoulder area of a Bathers in the tub compartment 7a and for the pelvic area To allow in the tub part space 7b. Preferably in the lower Tub area then closes a tub leg rest section 7c especially for the lower leg area which, if necessary, raised above the deepest sections the pan compartment spaces 7a and 7b is designed.

To the upper shoulder, neck and head area of the rises Trough floor stronger, so that when lying on a bather the shoulder, neck and especially head area is higher and at the usual use of the bath at least the Neck and head area not in contact with warm bathing medium comes.

The entire tub also preferably according to the Cross-sectional view of Figure 2 as soft as possible, slightly U-shaped contouring and curve shape, from the bottom of the tub or the tub support surface 3 to the side portions 11, the side tub walls or Tub sections coming from the bottom of the tub with outwards rising flanks rise.

Although the peripheral rim of the tub 13 is generally higher can be formed as this from Figure 1 and 2 is the reproduced height representation for the described and also partially discussed further below Use case quite sufficient. In the foot area Therefore, the bath rim 13 only towers over slightly the tub legrest section 7c.

The entire illustrated tub 1 is by means of a stand device 15 held and carried.

Furthermore, one of the tray orientation relative to a Horizontal plane changing positioning, swivel or Tilting device 17 may be provided. This is shown in the picture Embodiment by a transverse to Trough extending tilting axis 19 formed, which allows the tub 1 according to the arrow 21 in FIG 2 about this tilting axis 19 to the left and right, so the left longitudinal side and to the right longitudinal side back and forth to pivot. This can also in appropriate lateral tilting the entry and exit of the bather be relieved.

As with the schematic excerpt cross-sectional view according to FIG. 3 through the upper rim of the tub is shown, this is preferably at least light Convex shaped. The tub itself is made of suitable Material, usually plastic, acrylic etc. It but can also be an enameled pan. The Surface should preferably be as smooth as possible.

As is apparent from the enlarged detail cross-sectional view according to Figure 3 shows, is usually then when at Performing an application on the body certain essences, Care products or other application materials used and applied, or if, for example using a particular bath application certain bathing liquids to be performed before put a foil into the bath all over the bath. The tub is usually in unfilled Status. Subsequently, a bather can get in put the foil in the tub. The person concerned Thus, it is directly on the slide, due to the body weight with appropriate circulation of Body at the bottom of the tub and partly at the side Transition areas abuts the Wannenseitenbereich. These Presentation while putting in the tub is in Cross-sectional view shown schematically in Figure 8. In FIG. 8, the dashed line also indicates that that already next - if, for example, a bathing application should be carried out - in the area above the film 27 filled a certain bathing liquid can be. This bathing liquid 28 may be, for example but also be filled later. Instead of the bathing liquid 28 may be applied to such Badeflüssigkeit be waived if, for example, on Body of a bather only spreadable or pasty wraps or materials and media on the body surface or parts of the body surface previously applied have been. If only a heat application is performed become so on the body no materials at all applied or no flowable medium above the film 27 are filled.

Subsequently, the tub is usually warm with up hot water, depending on the application and needs, below the film 27 filled. The film edge 27 'is preferred placed over the trough circulation edge 13 and hangs loose outside the tub according to the length and width down the slide. Preferred is within the tub floor, For example, in the middle region of a water supply 29 provided (wherein such an inlet opening can also be provided in the sidewall area or it is by means of a hose after lifting the film 27th from the outside water in the area below the film 27th and the inside of the tub filled), wherein at one Fitting outside the tub the appropriate degree of heat and the inflow amount can be set in the time unit can.

During the rising below the film water level For example, by an operator's hand by lifting the film in the tray Hot water moistened and then with the moist Hand over the edge of the tub 13. Subsequently can the previously correspondingly slightly raised film with the overhanging film edge portion 27 'back on the previously moistened rim 13 are hung up. Thereby arises in a comparatively broad section, the in the cross-sectional representation above the film edge with 31 (Figure 3) is characterized, an almost full-surface Adhesion effect between film and material of the film edge, whereby so strong adhesion and holding forces be generated in the rising water about it on the slide lying person above the tub floor can be held.

This supporting function is also supported by that with increasing water filling in the tub Person feels "buoyant" buoyant forces, so that over the slide only partial forces added and must be kept.

Also during the increasingly higher filling of the tub can always taken the edge of the film, lifted off the edge of the tub and retighten the film, for example the person P in the tub is higher to be held and carried over the bottom of the tub. In FIG. 4 is a schematic cross-sectional view For example, a slide setting reproduced at the one below the film as warming Medium serving water especially on the back and also on the Press side of a person to be treated, wherein the film then from the side area of the body to the other Led edge 13 and there by the mentioned adhesion forces is attached.

But if, for example, a corresponding heat treatment over the heated water not only in the back and Support area, but also more on the body side area and / or for example even sections on the body top a person P are performed, so it is only required, the film 27 in sections on Lift film edge again from the edge 13 and so far to let go, for example, that in Figure 5 in Cross section (e.g., at the chest height of a person) Situation. By easing the film in the tub interior is now so much foil material been made available with increasing Water pressure, the film is virtually the one in the tub Person around, except for the Body top.

It can now be seen that the top of the film 27a also on the top of the body this largely with overlapping applies, so that the film bottom 27 b also upwards from the higher standing warm water 28 is lapped, leaving the whole body in this area from the warming medium here in the form of water surrounded and by the film 27 nevertheless of the water 28 floating separately in the water and still slightly held by the film.

In Figure 6 is shown schematically that in another Body portion area (e.g., leg portion B) Slide less far into the tub interior will, so there's the slide just on the bottom can put on the legs and in the side area of the legs B, but can not cover the upper part of the legs. In this case, the sections between the tub bottom 3 and the film bottom 27a due to the transverse direction the tub in this body section less available made film material larger than in the example according to FIG. 5.

Thus, in the simplest way an application be carried out, for example, under only on the skin applied media that are flowable or just pasty. Likewise, but also a bathing application be performed by placing in the area above the film one liter to usually a few liters Badefluigkeit be entered with certain Bath additives or comparatively expensive bathing media can be offset. The thin film 27 protects the Body and the liquid introduced above the film, because of a separating effect to that located below the film, usually made of water heat medium given is. This is reproduced, for example, in FIG. In the embodiment of FIG 7 is located below the film 27 as the heat medium serving liquid medium, usually hot water, being above the film 27, the bathing liquid 28 filled with certain additives, expensive bathing media, gentle to the skin, etc. may be added. In In this case, the person P almost only floats in this one Bathing medium.

In particular, even if in the tub at certain Make, for example, in the lower support area, on Transition area to the well side walls or at the side area additionally water outlet openings or nozzles 33 are arranged (in the cross-sectional view according to Figure 4 are each two nozzles 33 more in the sidewall area or at the transition area from the bottom of the tank to the sidewall area and a nozzle in the middle floor area the tub provided), so here may be with appropriate adjustment of the water outlet pressure, the water outlet and / or the temperature This water jet 34 additionally advantageous Effects are achieved. Because the exiting via the nozzles 33 Fluid jet 34 passes through the thin film 27 directly on the body or indirectly over the body between the film upper space and the body Application medium, where also the film as a quasi is not distracting. The in Figure 4 schematically shown nozzles 33 thereby generate a water jet 34, the quasi on the body-fitting foil 27 dents or depressions or deformations 36 in the film (and the body surface).

The nozzles 33 may be at different locations in the Be provided. They can be designed differently be. Preferably, however, the nozzles are arranged so and formed that the actual nozzle exit opening not on the actual tub support surface inside, especially when getting in and out, that is, at the beginning of an application or at the end of an application not an unpleasant resting on in the interior cause the tub projecting nozzles. Due to this can be placed in the tub bottom slight depressions be in which the water outlet openings or nozzles lie.

The mentioned thin film does not have to be so in the end be designed to be a bather with his full Body weight (without supply of water on the underside of the foil) can carry. The filling of the tub, however and the then adjusting "floating" or "floating" Condition generating the corresponding buoyancy forces This leads to a comparatively nonetheless sheer foil can be used as these Foil virtually no or only low load capacity in the Must use. Since a person is in the heat medium, which is entered in the tub below the foil, virtually swims, reduces the actual body weight usually to a value of less than 2 kg. From therefore, the foil ultimately only needs on this scale have sufficient carrying capacity to a person in one Such tub at different altitudes depending on To adjust desire and need differently. capacities of 10 kg are usually sufficient by far. This causes the films used, in particular Disposable films, extremely thin. In addition, a Such a thin film from a bather, located above the film is barely perceived. Currents in the water below the film are transferred directly, so as if no foil had been used at all.

With the foil can for a bather depending on dressing or slackening of the film and attachment of the film section or film edge 27 'on the tub circulation edge 13th Any setting can be made. By accordingly different setting can thus the Immersion depth of the bather in the tub be adjusted which ultimately also determines the degree of overheating and that "Immersionsgefühl" can be controlled and changed.

Preferably, the tub circulation edge is rounded, so at least slightly convex. This facilitates that Setting sufficiently high adhesion forces between Foil and tub surface material after wetting the When circumferential edge. Because by the Adhäsionskräfte is the Foil virtually "glued" to the edge of the tub, can be but always peel off easily and "stick again".

The film thickness can vary widely. ever however, the thinner the film, the more advantageous they are achievable effects in this context. The film thickness preferably has a thickness of less than 1 mm, in particular a thickness of less than 0.1 mm or even 0.05 mm. Preferably, the film has a thickness of about 30μ, 20μ or even 10μ or 0.5μ and less on. The borders after down are not given, as long as the film at least still sufficiently tear-resistant.

It has already been mentioned that at the beginning of an application usually there is no water in the tub and the film is so worn that it is everywhere easily on the bottom of the tub and the inside of the tub rests. In this situation, a person can easily climb the tub interior and lay in the tub, because the film is relaxed and always on the bottom of the tub and optionally rests on the pan side inner wall, therefore, it does not have to carry any load-bearing forces. After the Person has hung up on the slide and after when needed on the body if necessary certain means and media for the application has been applied can - as explained - the tub interior below the film 27 with a Fluid, usually warmed up water, to be filled.

At the end of an application will also be back next Ensure that the water drains below the film can, for example, via a to feed 29 separately displaced inlet or via a connection 29, in the one functional position as an inlet and in the other functional position serves as a drain. possibly the tub can also be tilted to make sure that, for example, in the foot area in one there provided catch basin located below the film Water can drain. The above the film located Person becomes with draining water level with the Then slowly rest the foil on the bottom of the tub with completely subdued, not exciting foil 27. Da even in this condition, the film 27 is not the person the person concerned can easily get off without the film breaking.

After the application, the disposable foil can be thrown away and disposed of. For a next application a new slide is used.

However, another use of the film is possible. Notwithstanding the previously described embodiments It is namely conceivable that the film from the Tub is removed, at a time while the bather is still in the tub in the room above the film is located. That is, the film becomes too. one time removed, to which the liquid medium below the film is still in the tub. The bather dives then completely into the bathing medium. The foil can also at a time below that in the tub person to be pulled out while the liquid medium below the foil may be present already partially drained. Any modifications are possible without restriction.
