Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described, Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. In one example embodiment, a system for providing negative-pressure and instillation to a tissue site may comprise a negative-pressure device and an instillation device. The negative-pressure device may comprise a negative-pressure source and a controller electrically coupled to the negative-pressure source. The instillation device may comprise a dosing valve having a dosing chamber including a dosing outlet configured to be fluidly coupled to a fluid port and a dosing inlet configured to be fluidly coupled to a source of instillation solution. The dosing valve may also have a working chamber including a biasing element operably engaged to the dosing chamber and configured to be fluidly coupled to the negative-pressure source. In some embodiments of the system, the instillation device may further comprise a wireless transceiver configured to communicate with the controller, and at least one sensor coupled to the wireless transceiver to provide a signal indicative of an operating condition of the dosing valve, and wherein the wireless transceiver is configured to communicate the at least one signal to the controller.

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.

A medical/surgical lavage unit including internal ribs that extend into a void space of a suction tube attached to the lavage unit.

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 and/or stoma of a user and for expelling of the irrigating liquid from the catheter tip, the catheter further comprising an expandable retention element (104), such as a balloon. A pump (101) is provided to pump the irrigating liquid from the reservoir to the catheter tip, and a user-operable control interface (123;125) comprising a dedicated emergency stop zone (125) is provided for receiving user input to withdraw the irrigating liquid from the retention element (100) for purging thereof in any operational state of the system.

A weighing system for medical applications may include a basin that has a base and a sloped sidewall that collectively form a bounded cavity with open top surface that receives and holds the material to be weighed. The basin may be free floating above the weighing device within a restricted range of travel. In some examples, the weighing system includes a thermal treatment device to adjust the temperature of the material in the basin. The rate at which heat is delivered to the basin may vary depending on the weight of the contents in the basin.

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.

Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described. Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. A pneumatic actuator may be mechanically coupled to a disposable distribution system that can provide a fluid path between the solution source and a distribution component. A bacterial filter may be disposed in the fluid path between the actuator and the distribution component to prevent contamination of the actuator during operation. The distribution system may be separated from the actuator and disposed of after operation, and the actuator may be re-used.

A combination hanger arm extension and pump cover device can be used with an instillation unit. The device includes a body portion that has a first end and a second end. A hook extends from the first end, and a tab extends from the body proximate the hook. A panel is disposed proximate the second end. A substantially rectangular sleeve extends at least partially through the body. The sleeve is disposed between the first and second end.

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 microenvironment of a biological body is controlled, and more particularly, is measured, changed, and monitored with respect to temperature, pH level, moisture and other tissue parameters of a region of the body while, optionally, administering a therapeutic agent to that region.
