A wound irrigation system and method of making and using. The system uses a pored, closed-ended delivery conduit to enhance the consistency and speed with which anti-microbial or related irrigation fluids may be delivered in order to promote cleansing, debridement and biofilm reduction in wounds. The ease of use of the system as a moist wound healing cascade makes it applicable to both in-home and in-facility environments that is not offered through traditional instillation negative pressure systems. In one form, the fluid delivery conduit is used as part of a dual-conduit approach in order to also help promote the removal of drainage, waste, irrigation overflow or other fluid from the wound. Utilization of such a pored, closed-ended delivery conduit in conjunction with a separate drainage conduit infusing helps reduce the frequency of dressing changes as well as the likelihood of microorganism formation and colonization.

A disposable flushing and suction drainage tube and a-using method thereof comprises a flushing tube, a suction tube, and a mounting base. The flushing tube and the suction tube are respectively mounted at one end of the mounting base, and an air connector and a water connector are mounted at the other end; the mounting base comprises a tube body base and a control base, the flushing tube and the suction tube are mounted at one end of the tube body base, and the other end is detachably connected to the control base. The disposable flushing and suction drainage tube controls suction for the suction tube by a negative pressure adjusting opening on the mounting base; opening, closing, and water flow of the flushing tube is controlled by a water control switch on the mounting base, and switching between flushing and drainage and the flow of drainage can be controlled.

A trans anal irrigation device that can be used on a bed. The device includes a rectal catheter connected to an irrigation fluid supply. A waste collection bag is also connected to the catheter. The catheter may be insertable in a seat attached to a fluid supply line. A valve in one of the catheter or seat selectably allows or prevents fluid communication between the catheter and a waste collection bag. The catheter may include an inflationless cuff made of a flexible material that permits it to be inserted in the rectum to prevent leakage around the exterior of the catheter.

A fluid management system for use in a tissue resection procedure includes a controller. An inflow pump is operated by the controller and configured to provide fluid inflow through a flow path to a site in patient's body. An outflow pump is operated by the controller and configured to provide fluid outflow through a flow path from the site in patient's body. A motor driven resecting device may be provided for resecting tissue at the site. The controller is configured to actuate an inflow pump and an outflow pump in response to various signals and various algorithms are provided to provide malfunction warnings and assure safe operation.

There is provided a colon cleaning device comprising: a tube through which liquid and fecal matter are removed from a colon of a patient, the tube having a longitudinal axis; a cleaning head positioned at the distal end of the tube, the cleaning head having at least one opening coaxial with the longitudinal axis, the at least one opening sized for fecal matter to enter the interior of the cleaning head from the colon; at least one disassembly element disposed within the cleaning head; and an actuating mechanism which actuates the disassembly element to perform sweeping displacement inside the cleaning head so that the at least one disassembly element rotates around the longitudinal axis to slice through the fecal matter; wherein the cleaning head and the tube are sized and shaped to be displaced along the colon of a patient.

A device for intermittently triggering a coordinated defecation reflex in the rectum or colon of a patient, said device comprising a catheter with an inflexible catheter shaft and a preformed inflatable balloon, the inflatable balloon comprising at least an intrarectal balloon segment having, in an inflated, but unpressurized state of the balloon, a generally spherical or discoid shape and a maximal first radius, and being adapted to be placed intrarectally; wherein the inflatable balloon is fixed onto the catheter shaft only at fixation points located at the ends of the inflatable balloon, wherein both ends of the inflatable balloon taper to a shaft dimension of the catheter shaft supporting the inflatable balloon, with the distal end of the balloon having a tapered second radius; wherein, in an inflated, but unpressurized state of the balloon, the difference between the first radius of the intrarectal balloon segment and the second radius of the distal tapered balloon end is equal to a first difference, and further wherein the first difference is greater than a distance between a distal front side of the catheter and a distal fixation point, where the tapered distal end of the balloon is in contact with the catheter shaft and is fixed thereto; wherein the distal front side of the catheter is at a distalmost extension of the catheter shaft or of a distal tip piece of the catheter shaft; and wherein the inflatable balloon is configured such that when the inflatable balloon is in a pressurized state exceeding 30 mbar, at least a portion of the distal intrarectal balloon segment engages and expands a side wall of the rectum or colon of the patient, whereby to trigger a coordinated defecation reflex in the rectum or colon of the patient.

A phacoemulsification simulation apparatus includes a trigger device, at least two sensors, and a processor. The trigger device configured to apply, to fluid at an inlet of a needle of a phacoemulsifier, a pressure profile as a function of time in response to an input waveform. The at least two sensors are configured to measure a pressure of the fluid at respective points in the phacoemulsification simulation apparatus. The processor is configured to (a) drive the trigger device with the input waveform, thereby causing the trigger device to apply the pressure profile to the inlet while the fluid is aspirated via an aspiration line, (b) receive measurements of the pressure of the fluid from the at least two sensors, and (c) analyze an aspiration performance of the phacoemulsifier in response to the measurements.

A medical probe includes a probe body shaped to define a distal section of a fluid channel, a cartridge, which is shaped to define a proximal section of the fluid channel and comprises a valve configured to regulate flow of a fluid through the proximal section of the fluid channel, and a clip configured to reversibly couple the cartridge with the probe body by sliding over the probe body and the cartridge while the cartridge contacts the probe body such that the proximal section of the fluid channel is in fluidic communication with the distal section of the fluid channel. Other embodiments are also described.

A fluid pump system having a first fluid pump for pumping fluid from a source to a surgical site and a second fluid pump for removing fluid from the surgical site at a first predetermined rate, wherein said fluid pump system intermittently operates in conjunction with a surgical tool which, when operational, removes fluid from the surgical site at a second predetermined rate greater than said first predetermined rate, the improvement including a sensor for sensing a predetermined parameter of the surgical tool and providing an output signal indicating that the surgical tool is operating; and an actuating means responsive to said output signal to actuate said second fluid pump to remove fluid from the surgical site at second predetermined rate.

Provided is a method of cleaning a body cavity using a device by coupling a distal end portion of a first cannula to the housing such that a lumen is in fluid communication with the first portion of the inner volume, the first cannula coupled to a vacuum source, then coupling a distal end portion of a second cannula to the housing such that a lumen is in fluid communication with the second portion of the inner volume, the second cannula being coupled to a fluid source, inserting a portion of the housing into a body cavity, conveying a fluid from the fluid source to the body cavity via the lumen of the second cannula, and withdrawing the fluid from the body cavity into the vacuum source concurrently with the conveying the fluid, via the lumen of at least the first cannula.
