Definitions

  • This invention concerns a bed and the structure of a flat bed-base for use particularly in hospitals.
  • the invention is suited particularly, but not exclusively, for use in the technical equipment sector, and more specifically, for use in hospitals.
  • the current type of bed used in hospitals is the traditional one, that is, composed of a frame which is generally rectangular, on to which are attached a headboard and a footboard. At the base of the frame, feet can be fitted, either of the fixed type or of the type having castors. In addition, a device can be fitted below the spring-base which enables all or part of said base to be lifted.
  • a metal mesh which is generally made up of a 5 mm diameter iron filament. This is interwoven in such a way as to produce a series of square or rectangular links of around 5 cm x 5 cm. In this case the principal function of the metal mesh is to support the mattress and the weight of the body, which it does by adapting itself to the main shape of the body.
  • the traditional metal spring-base is composed of a collection of two or more adjacent meshes all on the same plane and hinged in such a way as to allow certain parts of a patient's body to be raised while the others remain flat.
  • the traditional spring-base is in fact full of inaccessible places such as, for example, the inside of the outer frame which is in contact with the external environment due to the presence of the screw holes necessary for fixing onto the metal spring-base.
  • the structure itself of the spring-base is unhygienic in that it is made up of many components, the various joints of which constitute a real receptacle for dirt, and thus are potentially dangerous due to the possible development of bacteria therein, which are difficult to remove from such places. In such cases, in order to clean the beds properly, they must be completely dismantled and all their parts cleaned separately.
  • These traditional beds also do not lend themselves to being sterilised, and can only be given a ordinary tunnel-wash using normal disinfectants, the result being an inferior degree of cleanliness.
  • the spring-base is made of metal and thus easily subject to oxidation, and progressive rusting, due on the one hand to the frequent washing of the beds, and on the other to the various uses to which the beds are put. For example if a bed is used by a long-term patient, it can come into contact with liquids which are strongly acidic, such as urine. Also, in cases where the traditional flat spring-base is made rigid by the addition of pieces of wood, there is inadequate aeration, and this is indispensable for the mattress to be able to breathe, and thus for the well-being of the patient. Furthermore, traditional types of spring-bases do not even have any convenient method of containing the mattress, which is just held in place by the footboard and the headboard, leaving the possibility of the mattress sliding off at either side.
  • baydur plastic should be used for pressing the solid components, namely : a part comprising a base, sides, a back and/or upper shelf; drawers with a cavity on the front forming the handle; sliding doors; as well as dividing panels.
  • the aim of the present invention is to avoid the above mentioned problems.
  • US-A3188660 discloses a hospital bed mattress, supported by a mattress supporting structure, composed of four flat hinged panels, the two longer ones being at the head and foot of the bed and the two intermediate ones being shorter than these and of different lengths.
  • This supporting structure is so made in order to be able to raise and lower certain areas of the body.
  • This mattress supporting structure is substantially a metallic spring (10) and for this reason it has the same drawbacks as previously described.
  • WO-A-9101099 (NORMA BOXMEER B.V.) describes a similar mattress supporting structure in four hinged panels, wherein each panel is made of foam material and includes a plurality of transverse slats supported by resilient members.
  • This solution has the drawback that it is difficult to clean and disinfect, due to its bulky construction and foam content.
  • this solution has a mattress protecting underlay, which may become damaged and thus allow penetration of soiling materials.
  • the bed-base is formed from several solid, essentially flat components, all on the same plane and hinged together, and in particular there are two corresponding with the respective edges near to the head- and/or foot-board, and two smaller intermediate ones. These components are produced by injection-moulding and/or pressing "baydur" plastic; around the edges tubular supporting frames are embedded in the plastic, and there are devices for aerating and containing the mattress.
  • the bed-base can be effectively sterilised to an extent never before reached, and essentially independently of the temperature, within normal values and times required, obtaining thereby a maximum degree of hygiene.
  • the absence of metal parts, and inaccessible areas such as cracks, lubricated joints, etc. means the elimination of those areas which can form a receptacle for dirt with the consequent growth of bacteria, and thus the level of hygiene is optimised.
  • this base represents a structural simplification and entails a substantial reduction in weight of the entire structure.
  • the bed and bed-base (A) for particular use in hospitals, is composed of a headboard and a corresponding footboard which are fixed perpendicularly to the said base (A) mounted on a lower frame (supported using the usual methods), by a series of small rotating wheels.
  • the bed-base structure (A) is formed of tilting planes (1, 1', 1'', 1''') which are attached in the middle to the under-lying support frame.
  • There are four components of the bed-base which are essentially solid planes (1, 1', 1'', 1''') as they are each made from one piece of material, that is, they are each moulded from "baydur" plastic.
  • each component has at least one pair of hinges (2, 2') which are attached to the side of the component which is facing the adjoining component.
  • the arrangement of the solid components (1, 1', 1'', 1''') of the bed-base (A) is such that the first two (1, 1''') which are in an end position, are larger than the other two in the middle position (1', 1''). It will also be noted that these two middle position components (1', 1'') are of different sizes.
  • Each component of baydur plastic (1, 1', 1'', 1''') has a tubular frame (3) embedded within its structure around the perimeter, which serves to support and strengthen it.
  • each component (1, 1', 1'', 1'') has a particular form, in that each has a series of openings or holes, formed by extracting material. These openings are like round-ended triangles (4), which extend transversally and face in opposite directions. The function of said openings (4) is in practice to allow a better aeration of the mattress which is placed on the surface of the bed-base (A). Furthermore, the components have transversal ribs (5) which allow the mattress to be slightly raised above the surface of the bed-base, thus leaving a space below the mattress which also aids ventilation.
  • a boundary (6) which in practice is nothing more than a border to each component, and is slightly raised in comparison to the rest of the component, delimits the position in which to place the mattress.
  • an edge for restraining the mattress (7) which is essentially an upturned "U” structure partially incorporated into component (1) and/or (1''').
