A wound irrigation system includes a first fluid including an ion rich compound having free available ions; and a second fluid including an oxidation-reduction potential increasing compound, the second fluid housed separately from the first fluid. Mixing the first and second fluids in a charging area forms an ionically charged fluid with an oxidation-reduction potential higher than a wound site oxidation-potential. The ionically charged fluid increases antimicrobial activity of the wound upon application.

Systems, methods, and apparatuses for providing instillation therapy with a negative-pressure source are described. The apparatus can include a housing having a dosing chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus can also include a moveable barrier disposed in the housing between the dosing chamber and the negative-pressure chamber. The housing includes a fluid inlet in fluid communication with the dosing chamber and a fluid outlet in fluid communication with the dosing chamber. The housing can also include a negative-pressure inlet in fluid communication with the negative-pressure chamber and a biasing element coupled to the moveable barrier. The biasing element is operable to move the moveable barrier between a charge position and a discharge position.

A vacuum motor has a piston that linearly oscillates in the internal space of a housing. A gas outlet and a gas inlet (supplying ambient air) located in the housing terminate in the space between the piston and the housing rear side. The piston never covers the outlet or inlet. A valve body closes the inlet. A pestle moves within the housing between the piston and valve body. When the piston moves toward the rear side of the space, the valve body moves against the force of a spring and opens the inlet. The free cross-section of the opened inlet is at least equal in size to the free cross-section of the outlet. A surgical drive system, a medical lavage system, and a medical device for brushing, rasping or sawing of tissue or boneall include the vacuum motor. Also disclosed is a method for operating the vacuum motor.

A multi-utility surgical instrument may include a nosecone, a handle, a housing sleeve, an actuation facilitating sleeve, a piston tube, a hypodermic tube, and an end plug. The hypodermic tube may be disposed within the piston tube; the piston tube may be disposed within the actuation facilitating sleeve; the actuation facilitating sleeve may be disposed within the housing sleeve; the end plug may be disposed within a portion of the housing sleeve; the housing sleeve and the end plug may be disposed within the handle; the nose cone may be fixed to a distal end of the handle; and the hypodermic tube may be fixed to the nosecone.

The apparatus can include a housing having a dosing chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus can also include a moveable barrier disposed in the housing between the dosing chamber and the negative-pressure chamber. The housing includes a fluid inlet in fluid communication with the dosing chamber and a fluid outlet in fluid communication with the dosing chamber. The housing can also include a negative-pressure inlet in fluid communication with the negative-pressure chamber and a biasing element coupled to the moveable barrier. The biasing element is operable to move the moveable barrier between a charge position and a discharge position.

A disposable gravity flow hydro-cleaning system. The disposable gravity flow hydro-cleaning system comprises of an irrigation gun that has a pump that is attached to a tubing that is connected to an elevated solution dispenser The elevated solution dispenser contains a solution that is used to remove debridement from a wound of a patient. The solution dispenser is either a solution bag or a solution bottle.

Systems, methods, and apparatuses for providing installation therapy and negative-pressure therapy are described. The apparatus includes a housing and a moveable barrier disposed in the housing to form a dosing chamber and a pressure chamber. The apparatus also includes a therapy conduit configured to be fluidly coupled to a pressure source and to a canister. The apparatus further includes a fluid inlet fluidly coupled to the dosing chamber and configured to be fluidly coupled to a fluid source and a fluid outlet fluidly coupled to the dosing chamber and configured to be fluidly coupled to a dressing. A pressure inlet is fluidly coupled to the therapy conduit and the pressure chamber; and a check valve is disposed in the therapy conduit.

A soft tip applicator with flexible tendrils attaches to a syringe for spreading expressed liquid from the syringe onto a surface, such as skin. A detachable connector engages a cannula hub allowing liquid to be drawn into the syringe for later expulsion onto the surface.

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.
