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.

Disclosed is a disposable stepless speed regulation medical pulse irrigator with an LED lamp, including an upper handle, a lower handle, a pump body, a fluid tube, stepless speed regulation control parts, a spray nozzle part, a power supply part and an LED lamp. The pump body is arranged inside the upper handle; the left side of the pump body is connected with a piston; and the bottom end of the piston is provided with a big gear. In a pulse irrigating process of a wound, the disposable stepless speed regulation medical pulse irrigator with the LED lamp can use a continuous regulatable flushing speed and pressure to reduce the discomfort of a patient with this instrument according to the wound pain sensitivity of the patient, and can improve the wound cleansing efficiency and relieve the working load of medical staff at the same time. When flushing fluid splashes onto a contaminated fluid collection bag to obstruct the field of view, the LED lamp can be turned on through an LED lamp control switch to assist in the observation for the wound, which facilitates debridement personnel to determine whether debridement is completed, so that the debridement time and cost are greatly saved.

A wound therapy system includes a dressing sealable over a wound and defining a wound space between the dressing and the wound, tubing fluidly communicable with the wound space, and a canister fluidly communicable with the tubing. The canister, the tubing, and the dressing define a sealed space that includes the wound space. The wound therapy system also includes a therapy unit coupled to the canister. The therapy unit includes a sensor configured to measure a pressure in the sealed space, a valve positioned between the sealed space and a surrounding environment and controllable between an open position and a closed position, and a control circuit. The control circuit is configured to control the valve to alternate between the open position and the closed position to allow airflow through the valve, receive measurements from the sensor, and determine a volume of the wound space based on the measurements.

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.

A method for operating a fluid pump of an ophthalmosurgical system for conveying a treatment fluid is provided. The fluid pump has a pump chamber and a drive chamber separated from the latter with an elastic partition element and which is acted upon by a drive fluid. A position of the partition element is detected. The method includes subjecting the drive fluid to a first drive pressure, detecting a treatment fluid pressure present in the first position of the partition element, subjecting the drive fluid to a further drive pressure, at which the partition element adopts a further position, detecting the at least one further position of the partition element, and a further treatment fluid pressure present in this further position, and taking into account the treatment fluid pressures and drive pressures present in the respective positions account in the operation of the fluid pump.

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.
