Definitions

  • This invention relates to the field of cleansing hands and forearms and more particularly to scrubbing devices which employ jets of pressurized cleansing fluids.
  • the problem of providing a scrubbing device that can successfully eliminate the problems associated with manual scrubbing and in particular the frequent and time consuming manual preoperative scrubbing by surgeons and the members of a surgical team has been addressed by several prior patents.
  • MPI should do all of the foregoing quickly since in emergency situations the time consumed in manual scrubbing may be critical for the patient.
  • the provision of such a device should also find utility in other scrubbing applications where the same drawbacks to manual scrubbing persist such as in food handling, clean work environments such as, in the electronics industry, the medical supplies industry and the like.
  • Particular utility can be found in any application where the presence of bacteria in the work environment is to be controlled such as in microbiological laboratories and the like.
  • a fluid lavage unit for hand and forearm scrubbing that incorporates at least one inclined sleeve, and preferably two, for receiving an inserted hand and forearm for cleansing, with each comprising an open end sized to receive the hand and forearm and a closed end, with the longitudinal portion of the sleeve comprising at least two concentric walls wherein the outer wall is fluid-tight and the inner wall is foraminous; and the space defined by -the two walls communicating with a source of cleansing fluid under pressure.
  • the outer and inner walls -terminate in a fluid-tight manner at a closed end comprising a foraminous disc and an outer wall also defining therebetween a second closed space also in communication with a source of cleansing fluid under pressure.
  • the cleansing fluid is pumped into the first space defined by the longitudinal walls and separately into the chamber or second space at the closed end to provide two different pressure sprays onto the forearm and ends of the fingers from the same fluid source.
  • Fig. 1 is a perspective view of the scrubber of the present invention with the enclosure partially broken away to show some details of the sleeves inside.
  • Fig. 2 is a perspective view, partially broken away to show the double walled construction of a sleeve and its end plate.
  • Fig. 3 is an end view of the sleeve from the right hand end of Fig. 2.
  • Fig. 4 is a cross-sectional view of the end of the sleeve- taken along the lines and arrows 4-4 of Fig. 3.
  • Fig. 5 is a cross-sectional view, of the entire end of the sleeve from the inside of the sleeve taken generally along the lines and arrows 5-5 of Fig. 4.
  • Fig. 6 is a schematic of all of the components for operation of the scrubber system of the present invention.
  • the scrubber 10 in Fig. 1 consists of a base 11, an elevator support 12 and a cabinet 13.
  • the cabinet 13 is shown with a transparent front panel 14 having a hinge 15 and a return cylinder 16.
  • Disposed in the cabinet 13 are a pair of sleeves 20 and 21 with closed ends 22 and 23 and open ends 24 and 25, respectively, terminating a predetermined distance back of the access holes 26 and 27 formed in the front of the cabinet 13 by the intersection of the cover 14 and the base of the o cabinet (not numbered) .
  • Manifold 30 at the rear of cabinet 23 connects a fluid pump (not shown) and a source of fluid to the sleeves 20 and 21 and closed sleeve ends 22 and 23 through conduits shown generally as 31.
  • a drain pan 32 with a depressed central hole is provided for draining the fluid that runs out of the front sleeve ends 24 and 25 due to the sleeves being slightly inclined, preferably -about 15° (degrees) upward from the horizontal from the front to the rear of the cabinet 13.
  • the sleeve supports within the cabinet are not shown.
  • the elevator support 12 can be foot switch actuated to accommodate users of differing height for comfortable insertion of their hands and forearms into the sleeves 20 and 21 through access holes 26 and 2?. on the front of cabinet 13.
  • access holes 26 and 27 in cabinet 23 may optionally be provided with segmented pneumatically inflatable annular cuffs which can be controllably inflated to engage the ⁇ pper forearm of the user of the device throughout the scrubbing operation to help prevent cleansing fluid from getting to the outside of the cabinet by running down the forearm of the user.
  • the inflatable cuff or guard can of course be designed and constructed in any manner that will accomplish the foregoing objective.
  • One suitable way would be to provide at least three abutting annular segments which when inflated would gently engage the forearm while providing an essentially water-tight seal at the front of cabinet 23 in a manner such that excess fluid from the sleeve and forearms would fall into the drain pan 32 by virtue of the space between the cuffs
  • a sleeve 20 is shown with an outer wall 40 and a concentric inner wall 41 with fluid communication into the space between the walls being provided by conduits 31 terminating into a connector 32 0 through the outer wall 40 of sleeve 20.
  • Open end cap 24 is ring-shaped with a hole communicating with the interior of sleeve 20 into the space surrounded circumferentially by the foraminous inner wall 41.
  • Closed end cap 22 is shown with its holes communicating 5 with the area surrounded by inner wall 41 and shows some of the detail for sealing the space between the walls 40 and 41 that is present on both end pieces 24 and 22.
  • Two concentric grooves 44 and 45 are cut in the end caps 22 and 24 to receive the ends of sleeves 0 40 and 41.
  • Additional water proof packing may be received in the grooves to insure a fluid-tight seal and the end caps are pulled tight onto the sleeve by the threaded rod fasteners shown generally as 50 which fasteners are received in holes spaced 5 circumferentially around the end caps at locations on a flange portion of the end caps outside of the outer sleeve 40.
  • Figs. 3, 4 and 5 the detail of the closed end 22 of the sleeve 20 is shown with the threaded rod fasteners 50 pulling the concentric outer wall 40 and inner wall 41 into fluid-tight engagement with the grooves 44 and packing material or 0-ring 45.
  • the plenum 60 created by a recess cut in end 22 and covered with end cap 65 communicates with a source of fluid under pressure from conduit 31 received through the exterior of end cap 65.
  • Conduit 31 can be threadably received or affixed in any manner which will provide a fluid-tight seal under the pressures employed.
  • the plenum 60 also communicates with the interior of the sleeve 20 through holes 66.
  • the end cap 65 can be affixed by adhesive or any water-tight mechanical fastening scheme to the end 20 to completely seal the plenum 60 so that fluid under pressure from conduit 31 * will fill the plenum 60 and exit only to the interior of the sleeve 20 through the holes 66.
  • the optimum preferred sizes and locations for the holes if placed other than as shown herein should be selected in combination with the capacity of the fluid pump to provide between about 20 and 80 pounds per square inch of pressure and preferably around 40-60 pounds per square inch and most preferably about 50 pounds per square inch to the space between the walls 40 and 41 and to the plenum in the closed end.
  • the apparatus is capable of achieving the desired cleansing function in from 90 to 180 seconds after actuation of the pump.
  • Each of these manifolds is capable of being constructed with changes in hole size and number and overall volume in the space to provide for a predetermined pressure drop and therefore can be constructed in combination with the pump selected to each provide a different volume of fluid and resultant spray pressure for accomplishing the separate tasks required for effective cleansing.
  • the larger manifold around the foraminous wall of the sleeve will by virtue of the greater number of holes in the foraminous wall provide a larger amount of fluid at a lower resultant spray pressure than the spray pressure from the holes communicating with the fluid in the small end manifold.
  • the cleansing of the fingers, under the fingernails, etc., is therefore enhanced by selection or control of a pressure from the end manifold that is larger than the delivery pressure from the sprays delivered generally radially of the sleeve even though the pressure to these plenums are identical which pressure is sufficient to provide a uniform debride ent of the hands and under the nails while the lesser pressure and/or greater volume of fluid delivered radially provides the proper cleansing of the surface of forearms, the palms and back of the
  • the fluid can be heated and checked for the proper pressure and the like with appropriate controls for efficient operation.
  • Anti .Septic solutions can be employed effectively with the present system and available filters can be employed to provide 5 for their reuse.
  • filters can be employed to provide 5 for their reuse.
  • the following solutions can be employed alone or in combination or in a predetermined solution:
  • Benzethonium (Tradename V-Tergent 8x) - Pitman-Moore, Inc., Washington Crossing, NJ 08560 CHLORHEXIDINE (Tradename Nolvasau Surgical Scrub) - Fort Dodge Laboratories, Fort Dodge, IA 50501 (Virosan solution) Aio-Ceutic Laboratories, St. Joseph, MO 64502
