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.

Fecal management methods and apparatuses (e.g., devices, systems, etc.) are described herein. The fecal management apparatuses may apply one or more fecal removal cycles of suction and irrigation (and in some examples air) to actively remove fecal material. The apparatus may control the timing of delivery of the fecal removal cycles as well as the parameters of the applied suction, irrigation and/or air within and between fecal removal cycles.

An ear, nose, and throat irrigator includes a bottle body, a housing; a water pump, a first tube body, a second tube body, and a shielding cover. A first end of the housing is connected with the bottle body. A spray head is arranged on a second end of the housing. The water pump is arranged in the housing. A first end of the first tube body is inserted into the bottle body. A second end of the first tube body is connected with a water inlet joint of the water pump. A first end of the second tube body is connected with a water outlet joint the water pump. A second end of the second tube body is connected with the spray head. The shielding cover is arranged on the spray head. The shielding cover is configured to shield water sprayed from the spray head.

A fluid pump system having a first fluid pump for pumping fluid from a source to a surgical site and a second fluid pump for removing fluid from the surgical site at a first predetermined rate, wherein said fluid pump system intermittently operates in conjunction with a surgical tool which, when operational, removes fluid from the surgical site at a second predetermined rate greater than said first predetermined rate, the improvement including a sensor for sensing a predetermined parameter of the surgical tool and providing an output signal indicating that the surgical tool is operating; and an actuating means responsive to said output signal to actuate said second fluid pump to remove fluid from the surgical site at second predetermined rate.

An automatic cleaning and washing device for administering substances to a body is provided. An automatic cleaning and washing device for administering substances in the body, according to one embodiment, comprises: a main body that moves internal substances stored in a predetermined accommodation space to a front end electrically depending on an operation of a driving part moving forward or backward; and a nozzle part that is coupled to or separated from a connection part configured at the front end of the main body, is inserted at least partially into the human body while coupled to the connection part of the main body, and administers the internal substances into the human body through an injection hole configured at the front end depending on an operation of the driving part of the main body.

In one embodiment, an irrigated medical system includes a medical tool, an irrigation line configured to fluidically connect an irrigation reservoir storing irrigation fluid to the medical tool, and provide at least some of the irrigation fluid to the medical tool, a force sensor configured to be coupled with the irrigation reservoir, and provide a signal responsively to a force exerted by the irrigation reservoir on the force sensor over time as irrigation fluid in the irrigation reservoir is depleted, and a controller configured to find an irrigation rate of the irrigation fluid flowing in the irrigation line responsively to the signal.

A method for anal or stomal irrigation includes providing an irrigation system to a user and instructing the user to operate the system to expel the irrigating liquid from a catheter tip. The irrigation pressure is controlled with the control system in response to input from a sensor such that a pressure at the catheter tip approaches a predetermined threshold pressure value without exceeding the predetermined pressure value.

An endoscopic system may include an endoscope including a handle and an elongate shaft extending distally from the handle, wherein the handle includes an inflow port in fluid communication with the elongate shaft, the inflow port being configured to fluidly connect to a fluid inflow line, an electronically adjustable orifice associated with the inflow port, and control circuitry for receiving a signal of a current size of the electronically adjustable orifice and/or for sending a signal to change a size of the electronically adjustable orifice. The system may include a first pressure sensor disposed upstream of the electronically adjustable orifice and a second pressure sensor disposed downstream of the electronically adjustable orifice.

A pump cartridge for mounting on a drive rotor includes a roller assembly having first and second hubs maintained in a spaced apart relationship and defining an axis, and a plurality of planetary rollers arranged in a circumferentially spaced orientation about the axis, the rollers mounted to the hubs displacement radially outward. One or more compressible tubing lines are interposed between the rollers and an interior wall of the pump cartridge housing. The housing and the first and second hubs collectively define a passageway through which a spreader on the drive rotor extends and may be rotated relative to the roller assembly to displace the rollers radially outward to thereby compress the tubing lines against the interior wall. A coupling feature on the first hub engages a roller driving feature of the rotor, so that rotation of the rotor causes rotation of the roller assembly about the axis.

An extension conduit for use with a system for aspirating thrombus includes a passageway extending between a distal end and a proximal end of the extension conduit, and a combined hydraulic and electrical control carried on the extension conduit and configured to be activated by a user to activate an electric switch while opening a valve to allow flow through the passageway.
