Definitions

  • A47c 27/00 ABSTRACT OF THE DISCLOSURE Apparatus for and method of supporting and treating a hospital patient by a fluidized bed which includes a tank portion which is partially filled with a mass of granular material which is covered by a gas permeable flexible supporting member upon which the patient is disposed while the granular material is fluidized by the passage of air upwardly through the granular mass at a rate which will fluidize the granular mass to reduce the specific gravity thereof to a predetermined value best suited to float the patient disposed on the supporting member.
  • the gas permeable supporting member permits the gas to pass around and in contact with the body of the patient and the temperature, humidity and character of the gas may be controlled as best suits the needs of the patient.
  • This invention relates to a hospital bed particularly adapted for use by patients inflicted with severe burns or other injuries where it is painful or not conducive to recovery to lie on an ordinary bed.
  • a container partially filled with a granular material.
  • the granular material is supported in the container on a diffuser which allows gas to pass upwardly through it and into the granular material.
  • the container is covered by a sheet of porous material which allows gas to pass through it while preventing the granular material from also passing through it.
  • Means for blowing a gas upwardly through the granular material causing it to be fluidized and act as a liquid.
  • the patient will float on the bed as though he is floating on a dense liquid.
  • the gas passes through the porous covering sheet and aerates the patient which is important in the healing of burned areas of the body. If the blowing gas is shut off, the granular material will gradually settle and conform to the shape of the patient thus forming a natural contour bed.
  • the temperature, humidity and character of the gas passing around the patient may be regulated before its entry into the fluidized bed as best suits the need of the patient.
  • FIG. 1 is a perspective view of a bed constructed in accordance with this invention and showing a patient floating on the bed;
  • FIG. 2 is a vertical cross-section of FIG. 1;
  • FIG. 3 is an exploded perspective view of the bed of this invention.
  • 1 designates an open-topped tank, receiver or container which is preferably made out of some material which can be, easily cleaned and sterilized and sufliciently strong to support the components of the bed. It must also be fluid tight. Some possible materials are fiber glass, steel and epoxy-coated wood.
  • An expanded metal grate 5 having legs 6 fits into the tank 1 and rests on the bottom of the tank.
  • a porous sheet material 3 fits into the tank and lays on top of the grate 5. This acts as a diffuser and is sufliciently porous to allow the passage of gas and sufriciently nonporous to prevent the passage of a fine granular material.
  • This sheet material 3 should be of such a nature that when a gas passes through it, there is a low pressure drop across it.
  • An air chamber or plenum 4 is formed between the sheet and the bottom of the tank. Above the diffuser 3, the tank is partially filled with a granular material 9 as best shown in FIG. 2.
  • a flexible sheet of material 10 is placed over the top of the tank and allowed to settle onto the granular material as best shown in FIGS. 1 and 2.
  • This sheet 10 should be loosely fastened to the tank so that as it is raised and lowered, it will not become tight or be under tension. Any suitable fastening means (not shown) may be used.
  • This pliable sheet material is sufliciently porous to allow the passage of gas and sufficiently non-porous to prevent the passage of granular material.
  • An ordinary bed sheet may be used but the material used as dressing for burned areas of the body may be preferred.
  • a gas inlet 11 is placed in the tank 1 between the bottom of the tank and the grate 5 so that gas will enter the chamber 4.
  • a hose 12 connects a compressor (not shown) with the gas inlet and supplies gas under pressure to the chamber 4.
  • the gas then passes through the sheet 3 which acts as a diffuser to prevent jets of air from reaching the granular material.
  • a diffuser 3 the gas delivered from the compressor will be evenly distributed throughout the granular material.
  • the gas flows into the chamber 4 from the compressor, through the diifuser 3, fluidizes the granular material and then passes upwardly through porous sheet 10.
  • the gas flows through the granular material 9, it is suspended or floats in the air and thus is fluidized.
  • This phenomenon is widely used in chemical processes in the use of catalysts as shown in U.S. Patent No. 2,625,442.
  • the amount of gas passed through the granular material in this invention should not be such as to reach the dispersion stage. That is, the granular material should float in the gas which is passed through it, not be exhausted out the top of the container 1. Therefore, the proper air flow should be determined from the size of the bed, the size of the granular material and the size of the patient to be supported as well as other factors which will become apparent.
  • the patient lies in the bed and air or other gas is sup plied so that the granular material is fluidized.
  • the granular material acts as a liquid and the patient will float. Due to the buoyant force provided by this liquid-like medium, the weight of the patient is evenly distributed over all parts of his body. There is less pressure on the injured area, and recovery is hastened.
  • the fluidized material should have a specific gravity greater than one (1).
  • the granular material should, therefore, be fluidized until its specific gravity is somewhere between that of water, one (1), and the granular material when it is not fluidized.
  • the specific gravity of the fluidized material is dependent on the amount of granular material and the amount of air or gas.
  • a granular material is wide. Possible materials include sand, plastic beads and glass beads. Fluidization works best if a regular shaped material is used and a spherical shape seems to work best. A material should be used that will retain its shape; it should be inert so that when air or other gas is passed through it, the patients health will not be endangered. The material should be capable of being sterilized. The weight of the material becomes important in determining the final specific gravity of the fluidized granular material, the pressure drop across it and thus the amount of air flow required to fluidize it, and the strength of the container necessary to hold the material. The needs of the patient are also important when choosing a material.
  • glass beads seem to work best.
  • the size of these beads should be uniform in any one application. Glass beads in the range of .002 to .050 inch have been successfully used in the hospital bed.
  • a screen 7, shown in FIG. 3, may be passed through the granular material when it is in a fluidized state by lifting on handles 8. This method is useful for picking up any large objects which may have fallen into the granular material and for separating beads which have stuck together.
  • the other method of cleaning is to remove the granular material and sterilize it.
  • One method for removing the material is sucking it out by use of a vacuum cleaner or the like.
  • Another method is to have a port 2 in the side of the container 1 between the diffuser 3 and the porous sheet 10. When it is desired to remove the granular material, it is fluidized and the port 2 is opened. The granular material will then flow out of the port like any liquid.
  • Other methods of cleaning may be better suited for different materials or applications.
  • the compressor should also be equipped with slow opening valves to prevent rupture of the sheet material and air regulators to prevent pressure surges in the bed.
  • the bed may be used in orthopedic applications for fixation and traction.
  • the bed can be used to support patients in a prone position when it is not advisable in a. standard bed.
  • the hospital bed of this invention has many uses in the treatmetnt of patients which would otherwise require many pieces of equipment.
  • the bed of this invention can also be used in non-medical areas. The considerations of weightlessness in space can be tested by using this bed since the patient becomes essentially weightless when the bed is fluidized. There are also many cases in industry when it is desired to float an object but not in a liquid.
