  • This invention relates to a hospital bed and more particularly to a plastic foam bed having a flow of ventilating air from the top thereof.
  • liquid-filled mattresses such as that shown in U.S. Pat. No. 3,108,293.
  • Liquid-filled mattresses must have a cover to keep the patient out of contact with the liquid. This cover acts as a hammock and itself distributes pressure unevenly over the patients body. Both conventional and liquid-filled mattresses prevent air from circulating freely over areas of the patients body resting on the mattress.
  • Soft plastic foam has some characteristics of uniform support which make it attractive for possible use in a hospital bed.
  • the use of plastic foam instead of fluidized granules would also be attractive from the cost standpoint.
  • Employing lowdensity foam to support a patient provides a low-pressure uniform support by allowing the patient to sink down into the foam. Since the foam is a good insulator, heat and perspiration on the supporting areas becomes a problem.
  • the patient support includes a pressurized plastic foam filled container covered by an open pore foam sheet which serves as a plenum for the distribution of ventilating air to the supporting areas of the patients skin.
  • the pressurized container encloses a lamination of layers of plastic foam of differing density.
  • the pressurization of the container is controlled to vary the relative firmness of the support.
  • the softest support is that provided by the layers of low-density foam with no air pressure. As air pressure is increased, less and less of the patients weight is supported by the foam. When maximum pressure is obtained, nearly all of the patients weight is carried by the pressurized container.
  • the pressurized container is divided into airtight zones which are independently pressurized to control the relative firmness provided different parts of a patient.
  • FIG. 1 shows a cross section of the polyfoam and pneumatic support system of the invention
  • FIG. 2 is a cross section of the pressurized container enclosing the lamination of soft and medium density foam layers
  • FIG. 3 shows details of the pressurized container
  • FIG. 4 shows the support system in place in a conventional hospital bed.
  • the pressurized container 1 encloses a lamination of low and medium density plastic foams.
  • the container is covered with an open pore foam layer 2 which acts as a plenum for a supply of ventilating air.
  • This air is supplied from an air compressor 3 through the connecting hose 4.
  • the use of an open pore foam as an air plenum has significant advantages in a support system of this type. For example, the distribution of air from the open pore foam is more uniform than the distribution from a box perforated on its top surface and placed beneath a foam mattress, as described in Science and Medicine, April May, 1969, page 19. It is also more uniform than the flow of air through foam with openings extending all the way through the foam such as is shown in the aforementioned Figman U.S. Pat. No. 3,266,064.
  • the foam layer 2 may be a 2-inch thick open pore foam which is rigid enough that patient loading does not pinch off air flow through the pores, but soft enough to conform to the shape of the patients body.
  • a uniform air flow of between 0.5 to 1.5 feet per minute can be obtained from the top surface of the foam layer 2.
  • top foam sheet 5 above the open pore foam 2.
  • the top foam sheet 5 should be a low-density, semiclosed cell (not reticulated) foam.
  • One foam suitable for use is the polyether urethane flexible foam available from Napco Chemical Company, Plainfield, New Jersey, having a nominal density of 1.10-1.35 pounds per cubic foot.
  • the pressurized container 1, open pore foam layer 2, and top foam sheet 5 are all enclosed in a fabric cover 6.
  • the top of this cover particularly must be made of a material which will stretch, but which does not support the patient by a hammocking effect.
  • the typical material suitable for use is a nylon stretch-type material sold under the trade name of Banlon.
  • the ventilating air supplied to the hose 4, and the pressurizing air supplied through the hose 4a, are supplied from the air compressor 3.
  • the air compressor unit includes a flow control knob 7 and an airflow indicator 8.
  • the ventilating air may be heated and humidified as required.
  • the air compressor also includes a pressure control 9 and an air pressure indicator 10.
  • the unit should be capable of pressurizing the container 1 up to a pressure of 2 p.s.i.
  • the ability to change the firmness of support supplied by the pressurized container is quite desirable. It allows selecting the firmness particularly suited to the needs and desires of the individual patient. It is also desirable for an individual patient to vary the relative firmness of support from time to time to relieve monotony.
  • One compressor suitable for use is the vane-type air compressor.
  • the pressurized container 1 encloses a lamination of foams, the layers 11-14 being shown.
  • the laminations are of increasing density. That is, in most applications it will be desired to have more dense foam at the bottom.
  • the layer 11 may be a low-density semiclosed cell polyether urethane foam having an indentation load deflection (lLD) of 25 percent at 9 pounds.
  • Layer 12 typically may have an lLD of 25 percent at 12 pounds; layer 13 an ILD of 25 percent at to pounds and layer 14 an ILD of percent at to pounds.
  • the foam layers are enclosed in the fabric container I having an excess of fabric at the top to allow deflection uninfiuenced by a hammocking effect.
  • An air fitting 15 supplies the pressurizing air to the container.
  • the container is divided into 4-inch square cells by tensile cords which are fastened to the top of fabric container 1 and to a board 16 in the bottom of the container. Of course, the cells may be larger or smaller than 4 square inches.
  • FIG. 3 The attachment of the tensile cords between the board 16 and the top fabric is shown in FIG. 3. Note that the foam is compressed at the tie down at the corner of each convex pocket. Typical cords 17-20 divide the foam into 4-inch square cells. There is a dome of top fabric between each group of four cords. This allows depression of a particular cell without affecting other cells. The rows of cells along the edges may be pressurized separately from the other cells to allow a firm support along the edges of the bed. This provides firm support so that the edges of the container do not bulge out. This also provides a firm support at the edge when a person is getting into or out of the bed. As shown in FIG.
  • a separate piece of fabric 21 is used along the edge and is folded under to be attached to the baseboard along the line 22. This piece of fabric separates the enclosed cells from the remainder of the cells. This technique is also used to divide the rest of the sealed container into zones which can be separately pressurized.
  • the container is divided into three separate control zones.
  • Ducts 23, 24, and 25 supply separate sources of pressurizing air to the three zones.
  • Zone control of firmness is desirable, for example, to allow the patient to sit on a relatively firm support while his back remains on a soft support.
  • zone control of firmness facilitates handling of a patient in a supine position on a bedpan. The capability of softening a zone under the buttocks while maintaining the remainder of the support firm allows sliding the bedpan under the patient instead of lifting the patient.
  • FIG. 4 shows the support system in place on a conventional hospital bed.
  • the board 16 (not shown in FIG. 4) is hinged at appropriate places to allow bending along lines at the points 26, 27 and 28 so that the normal raising and lowering functions of a hospital bed can be accommodated.
  • Auxiliary orthopedic support members, such as the contoured heel pad 29, can be inserted in the foam at the appropriate places.
  • a system for uniformly supporting a patient comprising:
  • a source of ventilating air connected to said open pore reticulated foam layer producing a flow of air from the top of said foam layer for patient ventilation.
  • a system for uniformly supporting a patient comprising:
  • said pressurized container having separately pressurized cells around the periphery thereof, the cells around the periphery being supplied with air at a higher pressure than the remaining portion of said container to provide firmer support at the edges of said container,
  • a source of ventilating air connected to said open pore foam layer producing a flow of air from the top of said foam layer for patient ventilation.
