A system for anal and/or stomal irrigation of a user's bowel comprises a reservoir (102) for an irrigating liquid, a catheter (100) for insertion into the rectum and/or stoma of a user and for expelling of the irrigating liquid from a catheter tip, and an expandable retention element (104), such as a balloon, for fixation of the catheter tip within the user's rectum or stoma. Tubing and valve systems provide conduits for the irrigating liquid between the reservoir and the catheter and between the reservoir and the expandable retention element, a pump (101) being provided within the tubing system. The pump and the valve system is controllable to selectively pump the irrigating liquid into the expandable retention element, transfer the irrigating liquid through the catheter for expelling of the irrigating fluid from the catheter tip and into the user's rectum or stoma, and to withdraw the irrigating liquid from the retention element for purging thereof.

A system for anal and/or stomal irrigation comprises a reservoir (102) for an irrigating liquid, a catheter (100) comprising a catheter tip for insertion into the rectum or stoma of a user and for expelling of the irrigating liquid from the catheter tip, and a tubing system (121) providing a conduit for the irrigating liquid between the reservoir and the catheter tip. A pump (101) is provided to pump the irrigating liquid from the reservoir to the catheter tip, and a control system (103) controls a flow condition, such as the amount of liquid expelled at the catheter tip. A sensor (153) determines a measure of pressure in at least one first predetermined position in the tubing system and/or the catheter during operation of the pump, on the basis of which the flow condition is estimated. The control system is configured to control the pumping operation of the pump in response to the measure of pressure.

A system for anal or stomal irrigation comprises a reservoir (102) for an irrigating liquid; a catheter (100) comprising a catheter tip for insertion into the rectum or stoma, a thermo sensor (128) connected to the reservoir for obtaining a measure of a temperature within the reservoir, a tubing system and/or the catheter. A control system (103) operatively connected with the thermo sensor is configured to determine a temperature within the reservoir. A method for predicting a temperature in a reservoir for irrigation liquid is also provided.

A surgical instrument for irrigating a frontal sinus target site of a patient including a handle, an introducer, an irrigation channel, a nozzle, and an actuator assembly. The introducer extends from the handle and defines a proximal segment and a distal segment. At least a portion of the proximal segment is linear and at least a portion of the distal segment is relatively curved. The nozzle is fluidly connected to the irrigation channel, and is rotatably maintained at a distal end of the introducer. The actuator assembly includes an actuator maintained by the handle and connected to the nozzle. Movement of the actuator causes the nozzle to rotate relative to the introducer. The introducer can be sized and shaped in accordance with a size and a shape of a nasal passageway/frontal sinus of a human adult.

A method of determining a pressure of a body cavity with a controller of a fluid management system includes determining a pressure and a volume of a cuff disposed about a collapsible bag, determining a volume of the collapsible bag based on the pressure and the volume of the cuff, and determining a pressure of the collapsible bag based on the volume of the collapsible bag. The method also includes calculating a fluid flow from the collapsible bag into a body cavity from the collapsible bag and determining a pressure of the body cavity based on the fluid flow.

Disclosed are various embodiments for an anti-reflux tube-type enemator that is leakproof, easy-to-clean, and quickly inflates to provide a steady flow of solution. The anti-reflux enemator includes a nozzle comprising a nozzle outlet, a tube fluidly coupled to the nozzle, and an enema bulb fluidly coupled to the tube. The enema bulb is configured to store solution therein and, in response to a squeezing force applied to the enema bulb, direct the solution through the tube and the nozzle, and expel the solution through the nozzle outlet. An anti-reflux coupler is positioned between the enema bulb and the tube through which the solution passes from the enema bulb to the tube. One or more one-way air valves are positioned relative to an aperture of the enema bulb.

Systems and methods for cleaning a colon or other portion of an intestine include optional use of sensors to detect conditions of blockage of flow of materials within an evacuation channel used to remove fecal material from the body; and devices and methods for purging such blockages from the evacuation channel.

A lavage handle for facilitating at least one of an irrigation function and a suctioning function at a target zone preferably includes a portable body, a power-operated fluid-displacing mechanism in communication with said body wherein said fluid-displacing mechanism has one of a first operating mode for inducing outward irrigation of fluid towards the target zone and a second operating mode for inducing inward suction of fluid from the target zone. An actuation mechanism is located at said body and operable communicated with said fluid-displacing mechanism such that said fluid-displacing mechanism is selectively operated in at least one of said first operating mode and said second operating mode. The actuation mechanism may include an irrigation-inducing mechanism and/or a suction-inducing mechanism.

A fluid infusion system includes an air pump connected to an accumulator tank to produce pressurized air that is stored in the accumulator tank. The system can include one or more fluid bag chambers wherein each fluid bag chamber includes an inflatable bladder positioned inside the fluid bag chamber to apply pressure on the fluid bag supported inside the chamber. The fluid bag can be connected by a tube set to deliver fluid from the fluid bag to a surgical tool at a surgical site. The fluid can, for example, be irrigation fluid or distention fluid. The system can include a controller connected to the pump to control the pump to produce the pressurized air and an adjustable pressure regulator can be connected between the accumulator tank and the inflatable bladder to control the pressure of air delivered to the inflatable bladder and the pressure that the fluid is delivered to the surgical tool. A pressure sensor can be connected between the adjustable pressure regulator and the inflatable bladder to measure the air pressure delivered to the inflatable bladder and send the air pressure measurements to the controller. The controller can configure the system display to show the air pressure measured by the pressure sensor.

Disclosed is a colonic irrigator capable of cleansing the inside of the large intestine and removing impacted feces remaining inside the large intestine by spraying a cleansing solution into the large intestine. The colonic irrigator includes a cleansing body 10 having a laid down egg shape, having a spray hole 12 formed at a lifted portion 11 provided on the upper part thereof and having a cleansing solution channel 13 formed therein to communicate with the spray hole 12, and a connector 20 which has a screw part 21 formed at one side thereof so as to be connected to a shower hose 40, is bent at 90 degrees such that the other side is connected to the lower part of the cleansing body 10, and has a cleansing solution channel 23 formed therein to communicate with the cleansing solution channel 13 of the cleansing body 10, where the cleansing body 10 and the connector 20 are integrated.
