An appliance is provided for negative-pressure therapy of wounds on the human or animal body in which, on the one hand, a substance is delivered to a wound bed (W) and, on the other hand, fluids, in particular an exudate and the delivered substance, are aspirated from the wound bed by negative pressure. The appliance has a suction pump housing, with a suction pump arranged therein for aspirating the fluids from the wound bed (W), and a fluid collection container for collecting the aspirated fluids. Moreover, the appliance has a first measuring device and a second measuring device. The first measuring device serves to determine the quantity of the aspirated fluids, and the second measuring device serves to determine the quantity of the substance delivered to the body.

The liquid can include water, and optionally soap and a hemorrhoid treatment composition.

WOUND THERAPY SYSTEM WITH WOUND VOLUME ESTIMATION
20230001070 · 2023-01-05 ·

A volume of a wound is estimated using a dynamic pressure response measured during instillation of fluid to the wound using a negative pressure wound therapy system. A previously estimated wound volume may be used to detect and prevent overfill of fluid to the wound during future instillation events. For example, real-time pressure measurements may be compared to model data representative of expected pressure at a wound having a volume equal to the previously estimated wound volume, with instillation being stopped if the observed pressure varies from the expected pressure. A comparison of a total volume of fluid instilled to the wound may also be compared to the previously estimated wound volume to prevent overfill. The comparison of wound volume estimated based on an instillation event may also be compared to a wound volume estimated using other methods to provide a higher confidence wound volume estimate.

Combination suction and irrigation hand tool

An irrigation fluid dispensing tool well suited for use in a combination suction and irrigation tool has a frame carrying a surge flow pump formed of a flow controller of a manipulable handgrip of the tool handle, compressible irrigation fluid reservoir, and frame where the flow controller preferably is formed of a handle lever of the handgrip that is displaceable, preferably pivotable, between one or more of a surge flow actuation position, flow obstructing actuation position, and flow initiating position. The lever actuates a valve, preferably a pinch valve, when displaced toward the flow obstructing actuation position. The lever actuates the surge pump by compressing the reservoir, preferably squeeze bulb, against the frame when the handgrip is squeezed. The lever can be assembled to the frame in a protective shipping and storage position and is movable to a tool operating position providing irrigation fluid flow control during tool operation.

A method and apparatus that reduces the time and trauma associated with tissue removal procedures such as Ultrasound Assisted Liposuction, which emulsifies and then extracts unwanted adipose from a patient's target zone. Emulsification and suction are optimized and performed in a synchronous manner by a single apparatus to improve the outcome and minimize, if not eliminate, the limitations, risks and complications caused by current state of the art techniques.

Wound therapy system with wound volume estimation using geometric approximation

A wound therapy system includes an instillation fluid canister configured to contain an instillation fluid, a pump fluidly coupled to the instillation fluid canister and operable to deliver the instillation fluid from the instillation fluid canister to a wound, a user interface configured to receive user input indicating one or more geometric attributes of the wound, and a controller electronically coupled to the pump and the user interface. The controller is configured to determine a volume of the wound based on the user input, determine a volume of the instillation fluid to deliver to the wound based on the volume of the wound, and operate the pump to deliver the determined volume of the instillation fluid to the wound.

FLUID MANAGEMENT SYSTEM AND METHODS
20230218816 · 2023-07-13 · ·

A hysteroscopic fluid management system includes a saline source with an electrolyte concentration, at least one pressure mechanism for circulating saline to and from a targeted site and through a filter having filter characteristics back to the source, and a controller. The controller provides a saline inflow in a first flow path to the site and a saline outflow in a second flow path from the site through the filter and back to the source at a controlled flow rate. A diagnostic or therapeutic procedure is performed at the site in the presence of the saline. The filter characteristics and the controlled flow rate are selected to (1) cause substantially no change in the electrolyte concentration in the saline, (2) to prevent hemolysis of greater than 5% of filtered red blood cells exposed to the saline, and/or (3) to minimize effect on prothrombin time of plasma exposed to the filter.

PHACOEMULSIFIER WITH HERMETIC PROTECTION AGAINST DISTALLY-PROPAGATING PRESSURE PULSES
20230218437 · 2023-07-13 ·

A phacoemulsification system includes a hollow needle, an aspiration line, and a protection valve inserted in the aspiration line. The needle is configured to emulsify a lens of an eye. The aspiration line is for evacuating material from the eye. The protection valve includes a chamber, a piston and a seal. The chamber has an inlet for receiving the material arriving from the needle, and an outlet for flowing the material along the aspiration line. The piston is configured to move in the chamber between a first position that enables material flow between the inlet and the outlet, and a second position that blocks the material flow. The seal is coupled with the inlet and is configured, when the piston is in the second position, to compress between the piston and the inlet in response to a pressure pulse that propagates in the aspiration line, thereby hermetically sealing the inlet.
