Claim 3

The combination called for in claim 1 wherein said first portion has a circumferential extent substantially only sufficient to block communication between the first and third ports when the valve core is rotated to establish communication between the second and fourth port, said first portion blocking only the third port and said second portion blocking only the second port when the valve core is rotated to establish communication between the first and fourth ports, said first portion blocking communication between the first and second ports when the valve core is rotated to establish communication between the second and fourth ports when the valve core is rotated to establish communication between the first and third ports.

Claim 4

The combination called for in claim 2 wherein said receptacle comprises a compressible plastic bulb.

Claim 5

The combination called for in claim 2 wherein said receptacle comprises a syringe which includes a hollow sleeve connected to the fourth port and an axially shiftable plunger within said sleeve for alternately creating substantial pressure and vacuum at said fourth port.

Claim 6

The combination called for in claim 2 wherein the periphery of the valve core in the plane of said ports is open from the circumferentially opposite ends of the first portion to the adjacent one of the opposite ends of the second portion.

Claim 7

The combination called for in claim 2 wherein the periphery of the valve core in the plane of said passageways consists of two diametrically opposite portions in sealed relation with said bore which are separated by two open sections defining said passageways and which extend between the circumferentially adjacent ends of the two portions sealed with said bore.

Claim 8

An arrangement for irrigating a patient''s bladder following prostate or bladder surgery comprising, a valve having a valve body and a valve core rotatable in said body, said valve body having four generally perpendicularly related ports thereon and a conduit connected with each port, one of said conduits comprising a urinary catheter adapted to be inserted in the patient''s urinary tract, the second conduit being connected to a source of irrigating fluid, the third conduit being connected to an expandable collapsible receptacle for drawing fluid into said receptacle from said source through said valve and for discharging said fluid into said catheter through said valve, said fourth conduit being connected with a urinary drainage bag disposed at a level below said valve, a rotatable valve core in said valve body having passageways therein which, when the valve core is rotated to predetermined positions, are adapted to connect any two of said ports while blocking the two remaining ports, said passageways being arranged so that the valve core is rotatable in the following sequence: first connecting the source of irrigating fluid with the receptacle to draw a quantity of irrigating fluid into the receptacle; then connecting the receptacle to the catheter to first discharge the fluid from the receptacle into the patient''s urinary tract when the receptacle is collapsed and to retract the fluid from the urinary tract back into the receptacle when the latter is expanded; thereafter connecting the receptacle to the drainage bag to discharge the irrigating fluid and the matter irrigated from the bladder to the drainage bag; and finally connecting the catheter to the drainage bag to permit normal drainage of the bladder, said passageways comprising a first passageway extending diametrically through the valve core and two additional passageways angularly inclined to said first passageway, each of said two additional passageways having one side thereof in common throughout substantially its entire radial extent with said first passageway so that, when the valve core is disposed in any of said positions, all of the passageways therein are in communication with two of said ports at the radially outer ends thereof, whereby said three passageways form a single cavity in said valve core having substantially only three sides in the plane of said ports (namely, one side comprising one side of said first passageway and the other two sides each comprising the inclined side of each of the other two passageways) so that, when any of said passageways are connected to said drainage bag, the fluid in each of said passageways drains into the drainage bag.

Claim 9

An arrangement for irrigating a patient''s bladder following prostate or bladder surgery comprising, a valve having a valve body and a valve core rotatable in said body, said valve body having four generally perpendicularly related ports thereon and a conduit connected with each port, one of said conduits comprising a urinary catheter adapted to be inserted in the patient''s urinary tract, the second conduit being connected to a source of irrigating fluid, the third conduit being connected to an expandable collapsible receptacle for drawing fluid into said receptacle from said source through said valve and for discharging said fluid into said catheter through said valve, said fourth conduit being connected with a urinary drainage bag disposed at a level below said valve, a rotatable valve core in said valve body having passageways therein which, when the valve core is rotated to predetermined positions, are adapted to connect any two of said ports while blocking the two remaining ports, said passageways being arranged so that the valve core is rotatable in the following sequence: first connecting the source of irrigating fluid with the receptacle to draw a quantity of irrigating fluid into the receptacle; then connecting the receptacle to the catheter to first discharge the fluid from the receptacle into the patient''s urinary tract when the receptacle is collapsed and to retract the fluid from the urinary tract back into the receptacle when the latter is expanded; thereafter connecting the receptacle to the drainage bag to discharge the irrigating fluid and the matter irrigated from the bladder to the drainage bag; and finally connecting the catheter to the drainage bag to permit normal drainage of the bladder, said passageways comprising a first passageway extending diametrically through the valve core and two additional passageways angularly inclined to said first passageway, each of said two additional passageways having one side thereof in common throughout substantially its entire radial extent with said first passageway so that, when the valve core is disposed in any of said positions, all of the passageways therein are in communication with two of said ports at the radially outer ends thereof, whereby said three passageways form a single cavity in said valve core having substantially only three sides in the plane of said ports (namely, one side comprising one side of said first passageway and the other two sides each comprising the inclined side of each of the other two passageways) so that, when any of said passageways are connected to said drainage bag, the fluid in each of said passageways drains into the drainage bag.

Claim 10

An arrangement as called for in claim 7 wherein the first conduit extends upwardly from the valve to the source of irrigating fluid and the second conduit extends downwardly from the valve to the urinary drainage bag.
