An eyelid retractor and irrigation tool includes a handle portion defining a longitudinal first axis configured to be grasped by a user and a hook portion connected to the handle portion for retracting an eyelid. The hook portion of the tool includes: inwardly and outwardly facing walls, which are curved about a second axis, which is distinct from the first axis; an edge wall extending between the inwardly and outwardly facing walls; and an interior cavity defined by the walls. The tool further comprises at least one opening extending through the inwardly facing wall or the outwardly facing wall fluidly connected to the interior cavity and positioned such that fluid in the interior cavity passes through the at least one opening to irrigate portions of an eye including the eyelid.

Described herein is a stable oral liquid pharmaceutical product comprising sodium picosulfate, magnesium oxide and citric acid. Particularly, sodium picosulfate is physically separated from magnesium oxide and citric acid prior to dispensing and is mixed at the time of administration.

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.

A method is provided that includes intranasally dispensing nasal wash fluid into a nasal cavity of a subject. Thereafter, a specimen sample is collected by performing an anterior nares nasal swab. The specimen sample is tested for the presence of a virus using a lateral flow immunoassay test strip. Other embodiments are also described.

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.

A skin treatment device and a method to cleanse and balance pH value of skin. The skin treatment device includes a nozzle to be directed into contact with the skin of a subject. A vacuum pump may be operably coupled to the nozzle for generating a suction force of the nozzle to evacuate impurities from the skin. A liquid replenishing assembly may be operably coupled to the nozzle for atomizing liquid at a pre-defined pH value. The liquid from the liquid replenishing assembly may pass into the nozzle based on the pre-defined pH value. The first control valve may be connected to an outlet of the vacuum pump and an outlet of the liquid replenishing assembly for communication with the nozzle.

A pump and a pump controller which uses an algorithm to quickly achieve and maintain a stable plasma field in a surgical site are provided. The algorithm calculates an electrical characteristic value to determine if a suction rate by the pump should be increased or decreased to achieve the stable plasma field. A method of using the pump and the pump controller is also provided.

A wound irrigation device including a container with an opening along the outer surface of the container and a nozzle assembly coupled to the container and configured to selectively allow the liquid to exit the container when pressure is applied to the container.

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.
