A system for controlling aspiration of a phacoemulsification probe inserted into an eye includes an anti-vacuum surge (AVS) module, one or more sensors, a vacuum relief valve, and a processor. The AVS module is coupled with an aspiration channel of the probe and is configured to mitigate vacuum surges in the channel by regulating flow via the channel. The one or more sensors are configured to measure fluid parameters in the channel. The vacuum relief valve, which is fluidly coupled with the channel, is configured to controllably relieve vacuum in the channel. The processor is configured to identify a change in at least one of the fluid parameters by reading at least one of the one or more sensors, and, responsively to an identified change in fluid parameters, operate the vacuum relief valve using pulse width modulation (PWM) to maintain a pressure in the channel within a predefined range.

An irrigation system including a reservoir with an inlet adapted to guide liquid into the reservoir, the inlet defining a closure for closing the inlet, an insertion member defining an insertion end sized for insertion into a body cavity of a human being, the insertion member defining at least one opening, and a liquid tube fluidly connecting the reservoir with the insertion member, at least one of the reservoir and the insertion member being permanently fastened to the liquid tube and further including an electrical pump adapted to pump liquid from the reservoir and out through the at least one opening of the insertion member, the electrical pump adapted to be separable from the system.

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.

A method of treatment for mixed carbon dioxide, carbonic acid, saline and optional active additives for treating non-nasal ailments includes delivery of dosage of the treatment at specified flow rates, using a) main housing having a hollow central area containing the dosage; b) a dosage dispenser head located at the distal end of the main housing, and having at least one flow channel for movement of the dosage from the main housing through the dosage dispenser head and to external of the dosage dispenser head; c) a dosage release control component located between the main housing and the dosage dispenser head to permit flow of the dosage through the dosage dispenser head in response to increased pressure against the dosage; and d) a pressure-changing moveable component on the main housing.

An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

A surgical irrigation and suction apparatus includes a housing forming a handle and a barrel. The housing contains a suction tube for disposing of waste slurry and am irrigation tube for provision of irrigation fluid. The apparatus further includes a removable tube divided into an irrigation chamber and a suction chamber. The two chambers are collinearly arranged with respect to each other. The removable tube is coupled with the housing via a tube fitting. The apparatus further includes an inlet/outlet tip coupled with the other end of the removable tube, the tip including an outlet port and a plurality of inlet ports, respectively. The irrigation chamber terminates distal to the barrel with the tip arranged to spray the irrigation fluid through the outlet port. The suction chamber terminates distal to the barrel with the tip for recovery of the waste slurry through the plurality of inlet ports.

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 low-cost and simple-to-use system and method to facilitate a prophylactic pleural lavage protocol at the time of thoracostomy tube placement for traumatic hemothorax in order to reduce the need for secondary intervention for the management of retained hemothorax. The invention may be used in conjunction with existing chest tubes and be administered at the time of initial chest tube placement, and continued at the bedside (by a bedside nurse) over the duration of chest drainage, as necessary. The system includes an operator device that semi-automatically administers a pleural lavage protocol consisting of saline instillation, and suction to slow the clotting process, prevent “gelling” of blood, and maintain drainability.
