Definitions

  • Bedpan rinsers for hospitals customarily comprise a diverter valve casing extending from the right hand side of the flush pipe so that an offset elbow was necessary in the flush pipe so the spray arm on the right hand side of the flush pipe could be moved vertically and horizontally directly above the center line of the toilet bowl without being interfered with by the toilet seat.
  • This flush pipe offset arrangement presented an unsightly appearance to the installation and also introduced a restriction to the free flow of water because the diverter valve mechanism was located in the direct path of the water flow between the flush valve and toilet bowl.
  • This former diverter apparatus was also somewhat bulky and costly to produce since it consisted of many parts which had to be precisely machined to properly fit without leakage, and rugged enough to withstand hard usage in a hospital.
  • the spray arm after extended use and wear often tended to drop down and would not remain set in the position in which it was adjusted by the nurse rinsing the bedpan.
  • the diverter valve apparatus consists of a cylindrical shaped valve member to which the spray arm is attached.
  • the spray arm is movable both vertically and horizontally in a slot formed in the valve casing. In the vertical position the spray arm closes a diverter flow passage from the flush tube to the spray arm and in a horizontal position opens the passage.
  • the cylindrical valve member and casing are supported directly on the front side of the flush tube or pipe with practically no restriction to the free flow of water into the toilet bowl.
  • FIG. 1 is a front plan view of the apparatus shown in combination with a conventional toilet bowl and flush valve;
  • FIG. 2 is a side view of FIG. 1 shown in the rinsing position
  • FIG. 3 is a sectional front view of the diverter valve apparatus
  • FIG. 5 is partial cross-sectional view of the diverter mechanism taken along the line 5-5 of FIG. 3; while FIG. 6 is a detail sectional view of the diverter apparatus and spray arm and its spout shown in the bedpan rinsing position.
  • the bedpan rinsing apparatus is indicated generally at 12 and is interposed in the Hush pipe 7 between the flush valve 6 and the toilet bowl 5.
  • the apparatus 12 includes a spray arm 13 having a spout 14 at its end and when used for bedpan rinsing purposes, the toilet seat 10 is lifted as shown in FIG. 2, and the spray arm 13 swung downward from its vertical position to the horizontal position above the bedpan 15 as indicated in FIG. 2.
  • This bedpan rinsing action takes place desirably at the same time the toilet bowl is being flushed.
  • a hollow cylindrical shaped valve member 30 Supported on the front side of casing 20 and arranged horizontally on the front side of flush pipe 7 is a hollow cylindrical shaped valve member 30 which is adapted to revolve axially and is in slidable snug engagement with the semi-circular or curved front wall 31 of the casing 20.
  • the rear side 32 of the curved wall 31 projects only slightly into the flow passage through the diverter casing 20 and therefore does not restrict the free flow of water through the casing to any appreciable extent.
  • the rear curved wall 32 has a diverter passage 33 extending from the flow passage in the casing to the surface of the cylindrical valve member 30.
  • the spray arm 13 is supported in and projects from the side of the cylindrical valve member 30 midway between the ends of the cylinder valve.
  • a thicker walled tube 35 is connected to a thicker walled tube 35 at its lower end which is inserted in a projecting portion 36 formed in the hollow interior of the valve member 30.
  • the tube 35 is held in place in the valve member by a set screw 36a riding in annular groove 37 formed in tube 35.
  • An O-ring 38 on the end of tube 35 prevents leakage outward along the side of the spray arm 13.
  • the purpose of providing the set screw 36a and groove 37 is to enable the spray arm 13 to be axially rotated if desired when in the rinsing position so as to spray all around the inside surfaces of the bedpan.
  • the hollow cylindrical valve member 30 has a diverter passage 40 extending through its end wall adjacent the left hand side of the valve member as viewed from the front of the valve.
  • This diverter passage 40 is surrounded by and O-ring 41 which is adapted to slide around the inside surface of curved wall 32.
  • a pair of O-rings 42 and 43 are arranged around the outer surface of the cylindrical valve member 30 on opposite sides of the diverter passage 40 and O-ring 411. The rings prevent leakage outward between the valve member 30 and its front and rear supporting walls 31 and 32.
  • valve member 30 In order to assemble the cylindrical valve member 30 within its supporting casing and cylindrical walls 31 and 32, the valve member is first inserted endways into the casing 20 and then the spray arm 13 is pushed into the projection 36 after which the set screw 36a may or may not be tightened in groove 37 depending upon whether it is desired to axially revolve the spray arm or to have it remain fixed. This arrangement simplifies assembly and requires less securing parts. The valve member is thus held in place by the spray arm.
  • the lower end 45 of the spray arm 13 is open to the hollow interior of the cylindrical valve member 30 and when the valve member has been rotated into the spray diverter position as shown in FlG.
  • the spray arm 13 is movable from a vertical position to a horizontal position in a slot 50 formed in the front side 31 of the casing 20.
  • the upper movement is limited by a stop 51 constituting the upper end of the slot 50 and the lower movement is limited by the stop 52, the lower end of slot 50.
  • the slot 50 is wide enough so the spray arm slides easily along the sides without bind-
  • a former problem in bedpan rinsers was that at times the nurse had difficulty in moving the spray arm up or down due to the friction of the parts comprising the diverter valve member. This was often due to the necessity of tightening the various parts to prevent leakage. Other times the spray arm was so loose it drooped and did not remain in the position in which it was put.
  • the nurse In the operation of the diverter apparatus the nurse first raises the toilet seat 10, places the bedpan 15 in position in the toilet bowl 5 and then grasps the spout 14 and lowers the spray arm 13 to its horizontal position above the bedpan as depicted in FIG. 2. She then trips the handle 8 of the flush valve 6 to cause the flushing water to flow through the flush pipe 7 into the toilet bowl 5. Due to the fact that the spray arm 13 has now been lowered and rotated in slot 50 until stopped by stop 52, a portion of the water flow is diverted through the cylindrical valve member 30 into the spray arm 13. The path of the diverted flow extends from the main passage in casing 20 through diverter passages 33, 40, the interior of valve 30, the end 45 of the spray arm and through the same to the spout 14.
  • the flow through the diverter passages is sufficient to provide a thorough cleansing of the bedpan, without however detracting from the full flow of water into the toilet bowl.
  • the slight restriction 24 in the outlet end of casing 20 insures that sufficient back pressure is generated to cause the portion of the flow to be diverted.
  • the spray arm 13 is located directly on the front side of the flush pipe 7 which makes it more convenient and accessible for the nurse to grasp.
  • the spray arm is also shorter in length.
  • the cylindrical valve member and its supporting casing renders the unit desirably streamlined in appearance and by slightly offsetting the spray arm in the cylindrical valve member, enables the spray arm to be moved closer to the flush pipe in the upper position.
  • a cause of concern in prior bedpan rinser apparatus is that after the spray arm was moved into its vertical position and the flush valve 6 shut off, an unwanted dribble and residual expulsion of water occurred from the spout 14 of the spray arm. Since the spray arm is in its vertical position, the dribble would run down and fall upon the toilet seat 10 and the back of the toilet bowl 5, creating an unsanitary condition and necessitating a clean-up. In order to combat this undesirable, messy problem the spray spout shown in FIG. 6 has been designed.
  • the spout 14 comprises an annular clamping ring 65 threaded into the spout casing 14, and this ring 65 holds a spray disc 66 in position.
  • the disc 66 has spray holes therein for the water to pass through.
  • On the rear side of spray disc 66 there is press fitted a screen 67 made of close mesh corrosion-proof wire. This screen effectively prevents residual dribble from issuing from the spout and retains it in the spray arm 13.
