Definitions

  • This invention relates to patient transport systems, and more particularly, to a patient transport system for transferring an immobile patient from a bed to a gurney or vice versa.
  • roller boards which are inserted partially under the patient and then the patient is pulled onto the roller board. Again, the patient must be manipulated to allow the board to be inserted and then the body is pulled onto the board. In the end, the patient ends up on the board, not on the gurney or the bed.
  • An additional disadvantage of the roller board is that either the patient must cooperate with the transferrer or more than one transferrer is required to effect the transfer. Patients have also been known to drop off the roller boards and to land on the floor between the bed and the gurney.
  • the invention is an apparatus for transporting a patient that includes a base, a patient supporting member attached to the base, a conveyor secured (either fixedly or removably) to the base, and a sheet.
  • the sheet has a first end and a second end, where the first end is attached to the conveyor.
  • the sheet is adapted to be positioned onto the patient supporting member.
  • the base and the patient supporting member can form a bed, a gurney or an apparatus that converts from a gurney to a wheelchair or vice versa.
  • the conveyor includes a roller rotatably secured to the base, where the roller can be made of graphite fibers, aluminum, fiberglass or steel.
  • the roller includes a first end and a second end.
  • the sheet first end is attached to the roller and two bearings which are removably and rotatably secured to respective first and second ends of the roller.
  • Each bearing includes a first leg and a second leg attached to the first leg.
  • the first and second legs define an open ended roller receiving recess that receives an end of the roller.
  • a tip extends from one of the legs into the roller recess.
  • the tip extends from the first leg, which includes an inner surface having a first section and a second section, where the tip extends at an interface of the two sections.
  • the second leg includes a first segment and a depending second segment. The second segment is secured to the first leg. Inner surfaces of the first segment, second segment and second section define a roller engaging recess.
  • the second section inner surface is concave shaped.
  • a pair of collars are provided on both ends of the roller, wherein the bearings are received between the collars .
  • the sheet is removably attached to the conveyor by a flexible strap having one end releasably attached to the roller and the other end releasably attached to the sheet.
  • a clip is releasably secured at one end of the strap for attaching to the sheet.
  • the clip can include a body defining a slot and a plug received in the slot. The plug is adapted to sandwich and bind a portion of the sheet between the plug and the body.
  • the length of the strap can be adjusted.
  • Velcro ® fasteners are provided on an end of the strap and along the length of the roller so the strap can be releasably secured to the roller.
  • the roller can be provided with a telescopic arrangement so that its length can be adjusted, wherein the roller includes a first longitudinally extending member that slidably receives a second longitudinally extending member with a recess defined in the first longitudinally extending member.
  • the recess has the same geometric shape as a cross-sectional shape of the second longitudinal member.
  • a segmented handle can be attached to the roller.
  • An annular member is slidably received by the second longitudinally extending member and a flexible strip is secured to the annular member.
  • a tube can be attached to the base and a post can be attached to the bearing, or vice versa. The post is slidably received by the tube so that the bearing is removably secured to the base.
  • a pawl and ratchet arrangement can be secured to the roller and bearing to prevent the roller from rotating in a defined direction.
  • the invention can be used on a bed, a gurney or a convertible gurney that converts from a gurney to a wheelchair.
  • the invention is also a method for transporting a patient from a bed to a gurney or vice versa using the above-described conveyor including the steps of: placing a sheet on one of the mattress of the bed and the patient supporting surface of the gurney, positioning the patient on the sheet, attaching the conveyor to the other of the bed and the gurney having the sheet, positioning the gurney adjacent to the bed so that the conveyor is along a side of the other of the gurney and the bed, the side being furthest away from the one of the bed and the gurney having the sheet, removably attaching the sheet to the roller, rotating the roller and thereby winding the sheet around the roller, moving the patient on the sheet from the one of the bed and gurney toward the roller onto the other of the bed and the roller, and removing the roller from the one of the bed and the gurney.
  • the method can also include the steps of attaching the sheet to straps secured to the roller and adjusting the length of the straps after the patient begins to be moved on the sheet so that all of the straps are taut.

  • Conveyor 40 and the above-described methods for moving a patient from gurney 30 to bed 10 solve several problems in moving immobile patients.
  • conveyor 40 is inexpensive to manufacture and simple to operate, and overcomes many of the problems involved in the complex conveying mechanisms presently known in the art.
  • conveyor 40 utilizes a bed sheet 80 which is then used on the bed. This eliminates the need to move the patient by lifting the patient from gurney 30 to bed 10 or vice versa.
  • the patient need not be physically lifted by a nurse's aid or nurse because the patient is transported by the sheet.

  • the methods previously described attach the straps to the sheet or membrane using individual clips and individual straps .
  • the straps When deploying the straps from the rolled condition, it is possible that the straps will unroll unevenly because it is not possible for one person to grab all four or more clips to pull the straps off the roller at the same time. Consequently, the straps that are grabbed pull out while the ones not grabbed remain in a rolled condition and simply rotate with the roller. In other words, the straps get out of phase and require the operator to take time to rectify the situation by unrolling the rolled straps until they are the same length as the ones deployed by grabbing and pulling them out . This extra time can be eliminated by integrating all of the clips (usually three) attached to the roller into one integral clip arrangement 1100. This allows the operator to grab the center of the clip arrangement 1100 with one hand and pull a number of straps at one time.
