Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of a user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The source of saline solution is disposed relative to the device to provide gravitational inducement of the saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and a relative vacuum from the effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of the user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.

A system for irrigating and cleaning nasal cavities is provided. In some embodiments, the system includes a stand configured to hold an aqueous solution container. A primary incoming tube leading to a face mask device configured to be worn by a user. In one embodiment, the solution is gravity fed directed through the primary incoming tube into at least one port of the face mask device. A drain line leads from the face mask device to a collection container.

A device for carrying out a lavage-like, repetitive supply and draining of a flushing, cleaning or other therapeutically active substance in the context of a return-flow enema, the device comprising: a catheter unit (SK) for receiving and draining feces, which can be permanently placed atraumatically and anorectally; a flushing and collecting bag unit (5, SB) with a combined flushing and collecting function; and a hose unit (4) connecting the catheter unit (SK) to the flushing and collecting bag unit (5, SB), comprising a single-lumen or multi-lumen, film-like, flatly collapsible, hose, and enabling a bidirectional flow communication between the catheter unit (SK) and the flushing and collecting bag unit (5; SB); characterized by at least one throughflow element with a flow-direction-dependent throttle function, providing a large lumen for draining of the patient's intestinal contents into the flushing and collecting bag unit (5; SB), so that shaped stool fractions can be drained, and which facilitates a supply of liquid from the flushing and collecting bag unit (5; SB) towards the patient, but wherein the supply of liquid towards the patient is throttled, so as to be reduced in flow amount or flow speed in relation to the draining of the patient's intestinal contents and thereby reduces the supply of liquid to the patient to a non-irritating amount that is compatible with the patient avoiding painful sensations and/or vegetative responses by an immediate dilation of the patient's colon and/or a triggering of a premature or only partially coordinated defecation reflex.

Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of the user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The saline solution source bottle is disposed relative to the device to provide gravitational inducement of saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and the relative vacuum from an effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of a user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.

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 system for applying a lavage fluid to a surface, the system having a body configured to house a lavage fluid and at least two interchangeable application members configured to be in fluid communication with the body, wherein the at least two interchangeable application members includes a first application member and a second application member, the first application member being configured to dispense the lavage fluid with a first fluid flow force and/or first fluid flow pattern, and the second application member being configured to dispense the lavage fluid with a second fluid flow force and/or second fluid flow pattern that is different from the first fluid flow force and/or fluid flow pattern, respectively.

A system for applying a lavage fluid to a surface, the system having a body configured to house a lavage fluid and an application member in fluid communication with the body, wherein the application member has at least one nozzle, wherein the system is configured to dispense the lavage fluid with a first fluid flow force and a first fluid flow pattern, and wherein the nozzle is configured to selectably dispense the lavage fluid with a second fluid flow force and/or a second fluid flow pattern, wherein the second fluid flow force that is different from the first fluid flow force and the second fluid flow pattern is different from the first fluid flow pattern.

Disclosed are various embodiments for an anti-reflux enema bag having a pulley restrictor that acts as a waterflow restrictor, where the enema bag is leakproof, easy-to-clean, and provides a steady flow of solution. An enema bag system includes an enema bag, a nozzle comprising a nozzle outlet, and an anti-reflux coupler positioned between the enema bag and the nozzle through which the solution passes from the enema bag to the nozzle outlet. The anti-reflux coupler comprises an inlet for receiving at least a portion of the solution from the enema bag; an outlet for expelling the solution into the nozzle; and a check valve configured to prevent reflux of the solution from the nozzle. The enema bag system further comprises a pulley restrictor configured to selectively control a speed at which the solution is introduced into the nozzle and expelled from the nozzle outlet.

An inline flow control device for passive irrigation tubing to be used with electrophysiology devices, includes an elastically deformable diaphragm that can assume a neutral configuration, a first flexed configuration and a second flexed configuration in response to pressure change upstream or downstream of the diaphragm in self-adjusting the fluid flow to normalize the pressure change. In one embodiment, the diaphragm is unaffixed at least at its peripheral edge to allow the diaphragm to flex at its peripheral edge to vary the fluid flow through the device. In another embodiment, the diaphragm is fixed at its peripheral edge to allow the diaphragm to flex in its inner region to allow different movement of a piston through which the fluid flows in response to pressure changes upstream and downstream of the diaphragm.

The disclosure includes embodiments of an apparatus, a device, and methods to transform an infant feeding bottle into an infant gavage feeding apparatus. According to an embodiment, an infant gavage feeding apparatus can include an infant feeding bottle, a gavage milk delivery component, a retaining ring, and a cord component. In another embodiment, infant milk dual-delivery device to transform an infant feeding bottle to an alternate nipple feeding and gavage feeding apparatus includes a gavage milk delivery component, a retaining ring, and a nipple receiving component. The gavage milk delivery component and the nipple receiving component can be positioned in a branched or a stacked configuration. The device can include a flow closure component and a controller to transition the milk flow for a gavage feeding and nipple feeding. The device can include a funnel to allow milk in the nipple to flow back into the infant feeding bottle.
