Abstract

An apparatus for the automatic irrigation of urinary bladders includes a means to cycle the inflation, deflation and flushing of the bladder. The apparatus includes a supply vessel, two flow control valves, a supply tube with a bladder catheter and timing means to control one of the flow control valves. A pump, controlled by the timing means, may also be used.

Claims

1. An apparatus for urinary bladder irrigation comprising in combination:

a vessel containing a solution for irrigating the bladder, a first restrictive-type flow control means having its inlet connected to the outlet of the vessel, a supply tube carrying the irrigating solution, whose inlet is connected to the outlet of the flow control means, a catheter having an inlet tube and an outlet connection for respectively feeding and discharging the irrigating solution to the bladder, said inlet tube being connected to the outlet of the supply tube, a discharge tube whose inlet is connected to the outlet connection of the catheter, an outlet flow control means for blocking or permitting flow in the discharge tube, a timing means for operating the outlet flow control means according to a predetermined cycle of operations, a second restrictive type flow control means connected in parallel with the said first restrictive flow control means, said second restrictive flow control means is being connected to and operated automatically by command from the said timing means, according to a predetermined cycle.

2. An apparatus as described in claim 1 in which said second restrictive flow control device is of a two-position type, operated automatically by command from the timing means of the apparatus of claim 1, in which the first position of said second flow control valve blocks flow therethrough, and the second position permits a high rate of flow of the irrigating fluid, according to a predetermined cycle of operations.

3. An apparatus as described in claim 1 having, in addition, a power source, a pump inserted between the catheter inlet tube and the first restrictive flow control means, whiCh pump is driven from said power source energized by the timing means of the apparatus according to a predetermined cycle of operations.

4. An apparatus according to claim 3 which has, in addition, a bladder pressure sensing means which acts to control the outlet flow control means, which pressure sensing means acts to ensure a free flow condition of the outlet flow control means when a certain predetermined pressure is obtained within the bladder.
