Description: Multiple hygienic bed pad with glide function BASIS OP THE INVENTION The present invention relates to a hygienic bed product having a pulling sheet, whereby is meant a product which is shaped to be lenient to persons lying in bed, to protect the mattress and the bed against contamination and leakage of urine, of drainage and other liquids, and to be arranged for being reused after having been machine washed and drip-dried or tumble dried. PROBLEMS It is natural and usual that patients lying in bed, both children and grown up people and elderly persons give off liquids and contamination of various types, In order to prevent a person bound by bed from feeling discomfort, and for protecting the bed and the mattress lying on the bed and the bed support it has been usual to use some type of material which soaks up liquid and liquid type contamination, and which can be exchanged upon need. Such soaking materials can be in the form of an absorbing object of disposable type like soaking paper or any paper combination, cellulose tissue or a similar material, or it can be of reusable type, whereby, in the latter case, the absorbing object can be re-used. PRIOR ART A type of such a protective material having an absorbing object is shown in GB 2.202.738. In order to make it possible to turn a person lying in bed, what has to be done frequently so as to prevent building up of pressure wounds, the patient has to be turned over sideways. This can often be a hard job, which also often can cause discomfort to the person lying in bed. For facilitating such turning over of a patient it has been usual to use a "pulling sheet" placed under the patient and extending transversally to the longitudinal direction of the bed. When said pulling sheet is pulled sideways of the bed, using assisting personnel, usually also 01/21047 o assisted by pushing personnel, the patient will roll sideways without being moved any noticeable distance in the transversal direction of the bed, In this way it is possible to turn the patient to any desired position, without exposing the patient to any noticeable discomfort, usually between a position with the patient lying on one side to lying on the back or to a position lying on the opposite patient side, or whichever other desired position. Both the absorbing object and the pulling sheet have a relatively rough surface, and a displacement of the absorbing object and the pulling sheet may demand relatively great forces. In order to reduce the work for the personnel in turning a patient in toe above mentioned way there has sometimes been used a "sliding sheet" between the patient and the absorbing object and/or the pulling sheet. Such a sliding sheet can be anchored to the bed in that the edges of the sliding sheet if fold down and in under the sides of the mattress. The sliding sheet generally is made of a slippery material like rayon, a smooth plastic material etc. Since the patient easily can slide on the sliding sheet it may happen that the patient un-intentionally slides on said sliding sheet, and this may result in accidents. In the worst case the patient may even slide aside and fall down from the bed. The publication WO 96/06550 discloses a bed protection device comprising an absorbing object which is integral with parts of the bed sheet, and in which the absorbing object, at the top surface thereof has a layer of a sliding material, on which the patient is supposed to be able to move him/herself to the sides and up or down the bed. The parts of the sheet extending transversally outwards are to be fold in under the mattress thereby securing the bed protection device against the mattress. For preventing a patient from sliding out of the bed and eventually falling down to -the floor and hurting him/herself when moving on the sliding material layer said bed protection device is formed with hems at the upper surface of the bed protection device, which hems extend in the longitudinal direction of the bed a slight distance inside the edges of the mattress and the bed, so that the patient 01/21047 can feel, by manually sensing the said hems by his/her hands, where on the slide material layer he/she is placed. As long as the sliding material layer is dry said known device may operate satisfactorily and the patient can in many cases move him/herself to the sides and turn him/herself thereby making sure he/she does not slide out of the bed, by sensing the position of said hems. When a patient is to be turned he/she has to be lifted, and a pulling sheet is placed under the patient in a position between the patient and bed protection device. The patient is thereafter turned (rotated) in that the pulling sheet is pulled transversally to the bed, whereby the patient is rolled while the pulling sheet slides on the upper sliding-material layer of the bed protection device. During the turning operation the bed protection device lies fixedly anchored against the mattress. After the patient has been turned his/her position must be corrected, and thereafter the patient once again has to be lifted so that the pulling sheet can be removed. This operation is heavy and complicated. It is also a known fact that a wet material gives a rough surface. Therefore, when the sliding material layer of the known device becomes wet depending on leakage from the patient, the sliding property of said layer is drastically reduced and it can be difficult or impossible for the patient to turn him/herself, and it can be very heavy for the assisting personnel to turn the patient using a pulling sheet. In the known device moisture can penetrate both through the sliding mateπal layer to the absorbing object and up from the absorbing object to the sliding material layer. The object of the present Invention is to solve the problem of providing a hygienic bed product which overcomes the above mentioned disadvantages in the prioriy known devices, and which provides an integral product comprising a combination of an absorbing object, a sliding sheet and a pulling sheet, and which is formed so that the patient can not un-intentionally slide off the bed, in which the sliding sheet is arranged at the bottom side of the product, well protected against penetration of moisture, and in which the patient can be turned (rotated) without the need of applying a sliding sheet under the patient. The main part of the combined apparatus is an "absorbing object" of a 01/21047 4 highly soaking, inert fibrous material of a type known per se, which all around, or at least at its upper surface and its lower surface is covered with a soft fabric, for instance a micro fiber material which easily lets through liquid in the direction downwards/inwards but prevents a penetration of liquid out through said fabric in the opposite direction. A well operating absorbing object may have a thickness of 2-6 mm, or preferably 3-4 mm and should have a width which substantially corresponds to the width of the bed or the mattress thereof, for instance between 70-90 cm, or which is as much wider than the bed that the projecting parts can be fold in under the mattress. The hygienic product / absorbing object can have a varying extension in^he longitudinal direction of the bed, depending on the size and weight of the patient, for instance between 30-120 cm of preferably between 40-70 cm. According to the invention the bottom surface of the absorbing object is integral both with a moisture blocking layer which prevents further transfer of moisture, and with a sliding material layer, for instance a semi-slippery or a relatively slippery micro fiber. The combination product, comprising the absorbing object with the moisture blocking layer and the sliding material layer, should be formed so that it can be secured in the transversal direction by being fold in under the mattress so that the absorbing object with the sliding material layer can not unintentionally slide in the transversal direction of the bed. The moisture blocking layer and the sliding material layer can be sewed, welded, glued or secured in any other way to the bottom surface of the absorbing object. The risk of accidents is thereby eliminated at the same time as the personnel can still turn the patient by making the patient roll on the absorbing object, whereby the entire combination unit, thanks to the sliding material layer at the bottom surface of the unit, can be pulled to the desired side position of the bed. Said sliding material layer always is dry and has a maintained sliding ability. Thereafter said combination unit can be secured in that parts of the absorbing object or a part connected to said absorbing object is fold in under the mattress. For providing the part named "pulling sheet" in the combined apparatus 01/21047 _ according to the invention the combined unit, comprising an absorbing object, a moisture blocking layer and a sliding material layer, can be made so much wider than the mattress for which it is intended to be used that parts of the unit can be fold in under the mattress, or the unit can be formed with "wings" of a tearproof material, for instance a textile fabric of synthetic resin like polyesther, which wings are sewed or otherwise attached to the side edges of the absorbing object. The wings are used as a pulling attachment means / pulling sheet when turning the patient and side displacement of the absorbing object with the moisture blocking layer and the sliding material layer on the mattress and/or the bed support. It is also possible to form the absorbing object so wide that outer parts thereof can be fold in under the mattress and so that it can be used as a holding means when pulling the bed product at any side. In the latter case the sliding material part can extend only over the part of the absorbing object which corresponds to the width of the bed, but it is, of course, also possible to provided a sliding material layer over the entire bottom surface of the absorbing object. SHORT DESCRIPTION OF THE DRAWINGS Now the invention Is to be described more in detail with reference to the accompanying drawings which show a couple of embodiments. Figure 1 shows a first embodiment of a bed product according to the invention seen from above and fully fold out transversal to the longitudinal direction of the bed. Figure 2 shows the hygienic bed product according to the invention while being laid on a bed, and figure 3 shows the bed with the hygienic bed product secured to the bed. Figure 4 is a partial cross section view along line IV-IV of figure 3, and figure 5 is a cross section view in a further enlarged scale through a hygienic bed product according to the invention. Figure 6 diagrammatically illustrates how to turn a patient by means of the bed product according to the invention, and figure 7 shows, like in figure 1, an alternative embodiment of the hygienic bed product according to the invention seen from above, 01/21047 Q TECHNICAL DESCRIPTION The bed product according to figures 1 - 4 generally comprises an absorbing object 1 formed with a base layer 2 of an inert, strongly soaking material, preferably a fibrous material which, at the upper surface thereof, has a surface layer 3 of a soft material like a textile material which is solidly connected to the base layer 2 of the absorbing object, and which, at the bottom surface thereof, has a bottom layer 4 of the same type of mateπal. At the underside of the bottom layer 4 there is a moisture blocking layer 5 of a liquid tight material like polyurethane, rubber, synthetic rubber etc., which has been welded, glued or otherwise fixed to the bottom layer 4. At the underside of the moisture blocking layer 5 there is a sliding layer 6 of a material of a relatively slippery type, which is adapted to be able to easily slide on the mattress 7. At the sides of the bed product there are outwardly projecting wings 8 adapted to be used as "pulling sheet wings". The wings 8 can be separate or can be attached to the absorbing object 1 and/or to the moisture blocking layer 5 and/or to the sliding material layer 6, or the wings may be a part of the combination bed unit projecting outside of the bed mattress 7. In the drawings is indicated that the bed product is formed to fit a bed 9 in the transversal direction thereof, and in the illustrated case the absorbing object 1 has a width which substantially coincides with, or is greater than existing standard width of the bed 9 or the mattress 7 thereof, for instance a width of between 70 and 90 cm and a length - in longitudinal direction of the bed - which can be 40-100 cm, or more. The product unit 1 is intended to be placed in such position in the bed that the absorbing object is located in a position of the mattress 7 corresponding to the trunk of a person lying in bed, but if desired it can be formed longer and can be laid at any place of the bed, The absorbing object can be made with a base layer 2 of any known mateπal having good absorbing properties, for instance a fiber material, and it is all around, or at least at the upper surface and the bottom surface thereof, formed with a lenient surface layer 3, 4 of a soft fibrous fabric, a polyurethane film or any 1/21047 7 other known material, in particular a material which allows liquid to pass into the base layer 2 of the absorbing object but prevents liquid from passing in the opposite direction. At the underside, between the bottom layer 4 and the sliding material layer 6 the absorbing layer 2-4 is formed with a moisture blocking layer 5 of a liquid tight material for eliminating passage of liquid down to the mattress 7. In figure 4 is diagrammatically shown that the absorbing object 1 can be formed with an edge strip 10, and that also the moisture blocking layer 5 and the sliding mateπal layer 6 can be secured to the absorbing object by means of said edge strip 10. In the case that the wings 8a are formed as separate units also said wings 8a can be seόured by being fold inwards round the edge strip 10 and can be sewed, glued or fixed in a corresponding way, The sliding material layer 6 should be of a material having such sliding property that the product, without obvious difficulty, can be pulled sideways on the mattress 7 with the patient lying on the product 1. The sliding property of the sliding layer 5, however, should not be so great that the absorbing object unintentionally could slide on the mattress 7, A suitable material is a micro fiber material which is sewed or welded or in a corresponding way is fixed to the bottom surface 4 and the moisture blocking layer 5 of the product 1 , As indicated in figure 4 the sliding material layer 6 also can be secured to the absorbing object using the edge strip 10 which is sewed on the absorbing object. Thus, an edge strip 10 can be sewed or welded round the entire absorbing object. As shown in figure 4 the wings 8a can be fold in at the upper side and can be sew connected between the absorbing object 1 and the edge strip 10. Also the wings can have a corresponding edge strip extending round the wings 8. The wings 8 and 8a, respectively, should have such length in the direction transversal to the mattress 7 that they can be fold in under the mattress thereby fixing the bed product in relation to the bed support 9 with the mattress. The wings can be a part of the combined hygienic bed product, or they can be separate and made of a tearproof strong material allowing a pulling with only a reasonable force of the patient together with the absorbing object to the side of the mattress. An 01/21047 8 example or material is a loose fabric of polyesther or another non-soaking material. An important feature of the invention is that the bed product, as the entire product, should be made of en inert material and should be re-usable, and that it should, as the entire product, be machine washable and be drip dried of dried in a tumble dryer. In figures 2 and 3 are shown how the bed product is laid across the mattress 7 and how the wings 8 are fold in under the mattress 7 for securing the product in relation to the mattress. In figure 6 is indicated how a patient can be turned in that the wings 8 are pulled out and the entire product is pulled in one direction or the other 11 , 12 on the mattress 7 with the patient lying on the hygienic product 1. This is facilitated in that the sliding material layer 6 slides rather easily on the mattress 7. As mentioned above the absorbing object can be formed extended in the transversal direction so as to thereby form , with the intermediate part of thereof, an absorbing object 1a and with the sideways projecting outer parts thereof an equivalent to the pulling sheet part of the wings 8 of the previously described apparatus. The pulling sheet parts or the wings 8, 8a can, in the illustrated embodiments, be fold in under mattress 7 and can secure the entire combined hygienic bed product against same. An object having an absorbing product extending over the entire length of the product is, indeed, slightly more expensive to manufacture than an object having separate wings 8a but is, on the other hand, more simple to use and to be placed in the bed and is further advantageous in that it can be used for different wide beds.
