First design (V2.3)

What we learned:

  • A 28° panel offers glare reduction, however the front panel does not need to be so high (a flat part/table should be incorporated).
  • 4.5” diameter armholes still do not provide sufficient room.
  • Armholes need an extrusion and lip to properly hold gloves. (This version did not have a lip).
  • Armholes (225 mm from bottom) are still not high enough to be used ergonomically with all simulated cases.
  • The armhole extrusion provides a small platform for MDs to temporarily rest their arms.
  • 4.5 mm Acrylic sheet is sturdy with the additional bends.
  • 650 mm width is adequate to fit most patients.
  • 650 mm width will fit most general hospital beds, however it will need bed supports to fit an O.R. table (they are closer to 500 mm on average).
  • The lip near the front of the enclosure can be placed under a pillow, helping constrain the enclosure when the bed is ramped.
  • Feet on the sides of the box will inhibit ingress/egress, and should not be incorporated in future designs. (not present on this design, but an item discussed.)
  • A cutout in the RHS is important to allow the assistant to bring equipment into the workable area with his/her right hand.  However, this cutout is ergonomically too low still.
  • An additional arm hold should be incorporated for the assistants left hand.
  • Recommended 23” internal height directly above the patient to allow stylet removal  (this version not sufficient).
  • We can achieve proper forearm sealing by attaching a surgical latex glove to the lip and cutting off the fingers. (This is a disposable glove.)
  • Handles should be incorporated for transport and quick removal if necessary.
