Methods and systems for providing a flow of fluid to an endoscope. An illustrative container and tube set arranged and configured to couple to an endoscope may comprise a first container configured to contain a fluid and having a first port in fluid communication with a bottom portion thereof. A pressure vessel system may be in selective fluid communication with the first container. The pressure vessel system may include a manifold housing defining a cavity and including a first fluid inlet, a second fluid inlet, and a first fluid outlet. A first water supply tube may be in selective fluid communication with the cavity of the manifold housing and a first gas supply tube may be in operative fluid communication with the cavity of the manifold housing. A first flow control member may be positioned within the first fluid inlet.

A fluid management and medical device system may include a fluid management system and a medical device having one or more sensors proximate the distal end of the elongate shaft of the medical device. The controller of the fluid management system may be configured to calculate a fluid deficit when the distal end of the elongate shaft is disposed within a patient and configured to automatically pause fluid deficit calculation when the distal end of the elongate shaft is removed from the patient. In some instances the controller is configured to calculate the fluid deficit using rotational speed of the inflow pump in combination with a difference between a change in weight of a fluid supply source supplying fluid to the fluid management system and a change in weight of a collection container collecting fluid from the fluid management system.

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 kink-free tube is provided. The tube comprises a first part and a second part, both formed by a film material which is a multilayer film material, with an outer layer on opposite sides of at least one inner layer thereby providing enhanced characteristics with respect to burst pressure, anti-kink effect, and opening pressure.

A fluid delivery system, method, and apparatus for providing instillation therapy with a negative-pressure source is described. The apparatus includes a housing having an ambient chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus also includes a moveable barrier disposed in the housing between the ambient chamber and the negative-pressure chamber. The moveable barrier is operable to move between a charge position and a discharge position in response to negative pressure. A fluid source is disposed in the negative-pressure chamber and is collapsible in response to movement of the moveable barrier to the discharge position. The apparatus also includes a fluid outlet in fluid communication with the fluid source, a negative-pressure port in fluid communication with the negative-pressure chamber and configured to be coupled to a negative-pressure source, and a vent formed in the housing and fluidly coupled to the ambient chamber.

The invention relates to a device (100) for treating a tissue portion (W). The device (100) comprises an application apparatus (130) for applying a first composition, a second composition and a third composition for treating the tissue portion (W) to the tissue portion (W), with the application apparatus (130) comprising at least one application opening (131) for transferring the compositions from the application apparatus (130) to the tissue portion (W). The device comprises an exposure apparatus (140) for exposing the compositions applied to the tissue portion (W) to light, with the exposure apparatus (140) comprising an exit area (141) for the exit of the light from the exposure apparatus (140). The device (100) comprises a carrying apparatus (150), with the carrying apparatus (150) carrying the at least one application opening (131) and the exit area (141). The application apparatus (130) is designed to accommodate a replaceable cartridge (200) containing the first composition, the second composition and/or the third composition.

A surgical cleaning device and method of use having a housing, a drive shaft rotatably mounted, having a rear end and a front end, a brush head positioned at the front end and arranged outside the housing, to which a plurality of elastically deformable bristles are attached, a pump connected with the drive shaft for pumping a rinsing liquid, a gearbox that is connected with the front end of the drive shaft and with a rear end of the tube and which translates the rotational movement of the drive shaft into an oscillating linear movement of the tube and the brush head, wherein the tube is mounted movable in a linear manner; the brush head in the region of the elastically deformable bristles has at least one ejection opening, wherein the tube opens liquid-permeably through the at least one ejection opening in the direction of the elastically deformable bristles.

A fluid management and medical device system may include a fluid management system and a medical device having one or more sensors proximate the distal end of the elongate shaft of the medical device. The controller of the fluid management system may be configured to calculate a fluid deficit when the distal end of the elongate shaft is disposed within a patient and configured to automatically pause fluid deficit calculation when the distal end of the elongate shaft is removed from the patient. In some instances the controller is configured to calculate the fluid deficit using rotational speed of the inflow pump in combination with a difference between a change in weight of a fluid supply source supplying fluid to the fluid management system and a change in weight of a collection container collecting fluid from the fluid management system.

The present invention discloses a multi-functional bionic nasal irrigator, comprising a base, wherein a water pump for pumping water is arranged in the base, a key panel is arranged on an outer surface of the base, and a water pump water outlet pipe orifice connected to the water pump is arranged at the top of the base. A water-mist spray nozzle device and a water-column spray nozzle device that can be flexibly switched and mounted are designed on the base, main motor power is automatically adjusted according to assembling of different spray nozzle devices, the base is connected to the water-mist spray nozzle device and the water-column spray nozzle device both by clamping, and a diameter of a mist point water outlet hole of an atomization sheet is reduced to 0.15-0.26 mm, so that water mist sprayed has a smaller particle size.

A oronasal conjunctival spray may include a bottle for fluid and an applicator that may be screwable to the bottle. The spray applicator may include a nasal spray port for spraying fluid into a human nose, a conjunctival spray port for spraying fluid into a human eye, and an oral spray port for spraying fluid into a human oral cavity (mouth).
