Description

The invention relates to a foldable bed bath with self-supporting walls for medical and nursing purposes, especially for the cleaning and care of bedridden patients. The foldable bedding bath according to the invention is particularly suitable for use both in the private sector and in medical or care facilities for bathing and nursing bedridden persons or patients.

Bathtubs for medical and nursing purposes are known in the art.

In order to avoid the laborious lifting and carrying of a mobile patient from a bed to a bathtub, those bed bathtubs are particularly well known, which are formed of a waterproof, flexible material. Such a bed-bath is out DE 299 08 400 In this case, the patient, as happens when changing a sheet, is placed in bed on this flexible, waterproof surface. For their use, however, the watertight material will require an edge provided by laterally circulating means of support, eg rods passed through loops or holes and hung on the bedstead. Such bedding baths are not self-standing or not equipped with self-supporting walls or are built directly or indirectly to the bed frame and can not be used unaufwendig and spontaneously on any beds.

In addition, self-standing baths are known, which are inflatable as usual baby baths. In such a case, the bed bath is pushed in a deflated condition under the patient and then the tub is inflated under the patient, so that the water can not leak when bathing. However, this does not take into account the fact that conventional hospital beds are partially elevated for better patient comfort and more efficient cleaning. Due to the uncontrolled bending of the inflatable wall, this will bend at least at one point and can let the water through. Next baths are also known as DE 20 2005 009 113 U1 , whose edge elevation is formed of a deformable material.

Out US 5/107857 A For example, there is known a disposable decontamination apparatus that includes a foldable frame upon which a separate, water-impermeable coating can be placed to form a decontamination tray. The coating can be easily removed and disposed of after decontamination.

The bottom of the foldable bed-tub is made of a substantially flexible material and the walls of a substantially rigid material. In addition, two opposite upright walls have respective desired kinks. Preferably, the respective desired kinks are adapted to lift the wall portions of the two opposing upright walls at a first side of the desired kinks with respect to the wall portions of the two opposing upright walls at a second side of the desired kinks.

The foldable bed bath can preferably be designed so that the flexible foldable surface element is completely foldable and einfaltbar and from a sustainable, flexible, waterproof material, preferably plastic film or tarpaulin is formed.

In a preferred embodiment, the foldable bed bath is provided so that the flexible flatable flat element for easier insertion and removal has a plurality of surface parts by folding edges. The arrangement of the surface parts defines the bottom and the upright walls formed from end edges of the flexible foldable surface element. The bottom of the foldable bed-tub should correspond to the length and width of the bed-mattress to ensure a comfortable lying of the patient and an optimal support of the upright walls.

An advantageous embodiment of the foldable bed bath is constructed so that the corners of the flexible foldable surface element are folded up in the assembled state, thereby forming the bottom and the upright walls. The corners have securing means for a better grip, e.g. B. in the form of a hook and loop fastener.

According to the invention, each desired bending point has three converging desired folding edges, so that the foldable bedding bath is adjustable in height in stages. The desired kink of the foldable bed bath should be located at the point where the bed frame itself and the bed mattress are height adjustable. Thus, practically the headboard of the bed is lifted together with the foldable bed-bath for a comfortable lying of the patient.

According to a preferred embodiment, the foldable bed bath is constructed so that the plastic film or tarpaulin is glued or welded at the edge of surface parts, so that these surface parts are held in position and sealed sealing.

Other materials with similar or better properties can be used. The plastic film or tarpaulin is thus glued or welded around the plates, so that the surface parts are sealed sealing. Above all, the outer surface parts that form the four walls can be provided with plates to ensure a certain rigidity. Depending on the type of bed mattress, the bottom of the foldable bedding bath could either consist only of the film or be provided with plates for more stability.

Advantageously, the foldable bed bath is designed so that the polycarbonate plates or polycarbonate web plates have a thickness of 4 mm to 8 mm, with a thickness of approximately 6 mm being particularly preferred. In addition, it is conceivable to use two transversely superposed polycarbonate sheets or polycarbonate multi-wall sheets, so that a kind of grid is formed, which significantly increases the buckling strength in the longitudinal and transverse directions. The thickness of the two polycarbonate sheets or polycarbonate web sheets adhered transversely to one another is 2 × 4 mm to 2 × 6 mm, with a thickness of 2 × 4 mm being particularly preferred.

It is also advantageous if the flexible flatable flat element is formed of a more resistant plastic film with a thickness of at least 1 mm. In such a preferred embodiment, a so-called "memory" plastic film can be used, which automatically remembers places after the first folding during unfolding and folding. According to the invention the plastic film could be made from a truck tarpaulin with a thickness of about 1 mm. Also, a production of a polycarbonate film with a thickness of about 2 to 3 mm would be conceivable that has folded edges with "memory".

Further, it is preferably provided that one of the lateral surface parts has an opening for inserting a means for discharging the used liquid.

It is possible by the inventive foldable bed bath, easy to ensure at any time and any place, be it private apartment or hospital, an efficient cleaning and care for bedridden persons or patients. Due to the complete folding and unfolding of the bed bath is also very quickly used and can also be stowed without problems after their use.
