An assembly for dispensing fluid is described. In some implementations, an assembly can include a housing containing fluid, where the housing includes a conduit. The assembly can also include an actuator operably attached to the conduit of the housing. The actuator can include a body portion surrounding a cavity; a tip portion having a fluid path that is fluidly connected to the cavity, the cavity being fluidly connected to the conduit, and a channel support including a fluid passage space under pressure. The assembly can further include a collector having a collection zone configured to collect the fluid dispensed by the actuator.

There is provided a colon cleaning device comprising: a tube through which liquid and fecal matter are removed from a colon of a patient, the tube having a longitudinal axis; a cleaning head positioned at the distal end of the tube, the cleaning head having at least one opening coaxial with the longitudinal axis, the at least one opening sized for fecal matter to enter the interior of the cleaning head from the colon; at least one disassembly element disposed within the cleaning head; and an actuating mechanism which actuates the disassembly element to perform sweeping displacement inside the cleaning head so that the at least one disassembly element rotates around the longitudinal axis to slice through the fecal matter; wherein the cleaning head and the tube are sized and shaped to be displaced along the colon of a patient.

Disclosed are nozzles and nozzle assemblies of liquid jet-forming surgical instruments, surgical instruments employing such nozzles and/or nozzle assemblies, and methods of fabricating the nozzle assemblies in forming surgical instruments. Also, disclosed are liquid jet-forming surgical instruments including both liquid jet-forming nozzles and optional evacuation lumens, which when provided can be configured to receive the liquid jet and evacuate the liquid forming the liquid jet. Certain embodiments of such surgical instruments include inventive nozzle alignment component(s) to facilitate alignment of the nozzles and evacuation lumen upon assembly. In certain embodiments, surgical instruments are provided that include a nozzle that is shaped to form a liquid jet, which has surfaces that are optically smooth. In certain embodiments, the nozzle has a configuration enabling the nozzle to form a liquid jet that has the ability to remain collimated over longer distances than is typically achievable with conventional liquid jet surgical instrument nozzles having the same ratio of nozzle length to minimum inner diameter of the jet opening. In certain embodiments, nozzle assemblies comprising an operative assembly of at least two subcomponents, which together provide a nozzle are provided. In certain embodiments, the at least two sub-components may comprise a nozzle-providing component, such as a nozzle ring, and a holder that is configured to retain and position the nozzle-providing component in the nozzle assembly. In certain embodiments, the nozzle-providing component can comprise a liquid flow passage having a diameter that continuously decreases along at least a portion of its length.

An extremity drainage device, system, and method of use thereof are disclosed. The drainage device may be configured to collect a bodily fluid of a patient and/or a related irrigation fluid during a medical procedure. The drainage device may include a receptacle having a bottom surface and an outer wall extending upward from a perimeter of the bottom surface to an edge, the bottom surface and the outer wall defining a cavity. The edge may include a plurality of upper edge portions that substantially lie in a plane transverse to the outer wall and a plurality of lower edge portions, each lower edge portion connected to two upper edge portions. In addition, the lower edge portions may define in the outer wall at least two diametrically opposed side openings, each of the side openings having at least a partially curved profile at a bottom-most portion of the lower edge portion.

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.

The invention comprises an enema device configured for fluid delivery and evacuation managementwhich includes a retaining component for retaining a part of the enema device within the rectum, coupled with a collection component for collecting stool or liquid discharge received from the rectum. The device may additionally include a fluid delivery component to enable delivery of enema fluid to the colon, and/or a withdrawal component to support safe removal of the device from the patient.

Methods and systems for monitoring a waste stream in a surgical procedure. The method includes providing an irrigation fluid to a surgical area. The method may also include removing via a suction line the irrigation fluid and medical waste at the surgical area to generate a fluid stream in the suction line. The method may also monitoring the fluid stream based on a lateral flow test to generate a result. The method may also include providing feedback to a user based on the result.

A waste capturing device to use with a human in prone, or supine position. It provides air and water jets connected to water and air source to clean the genital area. This system improves on the ability to keep waste under control, especially in a bed.
