Definitions

  • the present invention relates to a bed system, such as a hospital bed system, comprising a base frame to be supported by a floor, a bed frame having a cavity for filling with a flexible material, and an overlay mattress covering the flexible material and the upper surface of the bed frame.
  • a bed system such as a hospital bed system
  • the upper surface of the bed frame and the upper surface of the flexible mattress material are in the same plane thereby evenly supporting the overlay mattress.
  • mattresses for hospital beds are well known in the art. While such mattresses according to the prior art provide a number of advantageous features, they nevertheless have certain limitations.
  • hospital beds are used to provide a support surface for patients or other individuals for treatment or rest.
  • Many such patient supports include a frame, a deck supported by the frame, a mattress, side rails configured to block egress of a patient from the mattress, and a controller configured to control one or more features of the bed.
  • a hospital bed including those used in nursing homes and other healthcare facilities, it is known to be able to adjust the height of the sleeping surface (e.g., the patient's mattress). For example, the sleeping surface is placed relatively low so that the patient can easily get up by himself, if permitted to do so, or even lower to limit the risk of injury in the event of a fall.
  • Inflatable bed systems are also known. Such known inflatable bed systems are capable of being used in conjunction with bed frames built to accommodate nonadjustable mattresses and foundations. A platform is provided, and support means are positioned above the platform. Inflatable bags are positioned between the platform and the support means.
  • inflatable mattresses have some advantages they are not as such suitable as the only mattress to support a patient. Only expensive mattress materials can be used as the only mattress to properly support a patient. However, such expensive mattresses are normally not implemented in hospitals.
  • the present invention seeks to overcome certain of these limitations and other drawbacks of the prior art, and to provide new features not heretofore available.
  • the present invention provides a bed system comprising:
  • a bed frame preferably made from aluminum, having a cavity for filling with a flexible material, such as a mattress material, said bed frame having upper, lower, and side surfaces;
  • said overlay mattress covering the flexible material and the upper surface of the bed frame, said overlay mattress is made from a viscoelastic material, such as memory foam;
  • the flexible mattress material is inflatable, such as one or more inflatable mattress modules.
  • the inflatable mattress is equipped with one or more pressure sensors to check if the correct pressure is maintained.
  • the pressure sensors are coupled via a controller and an air delivery means, such as pump, to regulate the pressure.
  • the flexible mattress material is made from one or more foam blocks fitting the cavity of the bed frame.
  • the present invention is based on the cost reduction in avoiding an expensive mattress j but using a thinner and thus cheaper overlay mattress that rest on the flexible material.
  • the area of upper surface of the bed frame is preferably 15-40%, preferably 20-35%, more preferably 25-30%, of the upper surface of the flexible mattress material.
  • system further comprises a device for holding a sheet laid in place on the overlay mattress, said device including an inflatable tube placed in a groove along the circumference of the bed frame, said device holding the sheet in place when inflated.
  • Figure 1 shows an elevated view of the bed frame and the cavity.
  • Figure 2 shows a cross sectional view of the bed frame with cavity filled with mattress material and covered with the overlay mattress.
  • a bed system with a bed frame comprising a cavity and an insert to fit said cavity.
  • the bed system provides a specialized bed frame with a cavity for the mattress insert.
  • the insert, placed within the bed frame cavity may
  • the insert may be based on foam blocks or inflatable mattress module(s).
  • the present invention can enable a hospital to adapt the flexibility of the support for patients with differing mattress support requirements.
  • the major advantage of the present invention is that any flexible material can be used in the cavity, while a more expensive j overlay mattress provides for optimum support and comfort.
  • the overlay mattress is made from a high quality mattress material (e.g. TEMPUR or another viscoelastic material) that is supported by the frame in the periphery (edge) area of the bed where no particular flexibility is required.
  • the insert may be formed from materials of varying densities, thereby being capable of support for persons of varying weights.
  • the mattress may comprise a plurality of cavities and a plurality of inserts to provide differing support capabilities in differing positions in the mattress.
  • the mattress may also be made from a foam product.
  • the inserts may be made from variable densities of foam.
  • a lighter density or a piece of foam product that is less firm may be used for lighter people, a medium density of foam product may be used for average people, and a high density of foam product for heavier people.
  • the exact size or depth or shape or design of the insert is entirely up to the designer.
  • This mattress insert is unique in that the mattress may be utilized as a particular type of mattress for a particular type of patient, such as the patient who has bed sores or might develop bed sores. Yet, it also may be used as a standard mattress for any other hospital patient. In the hospital, if the insert becomes contaminated, it may be disposed of and replaced. Different inserts formed from materials of varying densities may be used to provide support for persons of varying weights.
  • Any type of insert may be used which can comprise a plurality of individual support elements.
  • the plurality of individual support elements may have a base to aid in the independent support capability of each of the plurality of individual support elements. Any materials may be used to form the plurality of individuals support elements.
  • the plurality of individual support elements of the invention may be made from a foam product by cutting this into foam blocks.
  • a foam product may comprise any product of flexible foam, polyurethane, foam rubber, and any other comparable product.
  • the mattress materials described above are easily adaptable for hospital use for many types of patients, and can provide an inexpensive mattress for use by a patient for whom decubitus ulcers or bed sores may be a problem. They can also provide a relatively light mattress, easily adaptable for hospital use, for many types of patients.
  • the overlay mattress effectively mixes and selects the foregoing characteristics of foam materials (e.g. thickness and density) to provide an overlay mattress, which optimizes pressure dispersion for all parts of a patient's body, generally without regard to the nature of the prone position assumed by the patient or the body build of the patient.
  • foam materials e.g. thickness and density
  • FIG. 1 there is shown an elevated view of the bed frame (1) and the cavity with the elastic mattress material insert (2).
  • the bed frame (1) is mounted on a base frame (not shown), which is supported by a floor.
  • the insert (2) may be one or more foam blocks or an inflatable mattress material; importantly it is flexible and typically made from an inexpensive material.
  • FIG 2 there is shown a cross sectional view of the bed frame (1) with cavity filled with mattress material insert (2) and covered with the overlay mattress (3).
  • the overlay mattress (3) rests on both the hard bed frame (1), which is typically made from a metal (such as aluminum), and on the insert (2).
  • a patient laying in the bed will then rest with the head (via a pillow) on the hardly supported (by the bed frame) overlay mattress, while major parts of the body will rest on a combination of the insert (2) and the overlay mattress (3).
  • the present inventors have found that the experience is similar to a normal mattress made from the same material as the overlay mattress. This is truly surprising and indeed offers some essential advantages, such as ease of cleaning (the overlay mattress and the insert modules can be washed/cleaned separately) and significant cost reductions (the insert material is inexpensive, and the overlay mattress made an expensive material is thin).
