Fluid management systems are disclosed that include software-controlled, electro-mechanical devices used in combination with single-use or multi-use tubing sets. Functions of the fluid management systems can include fluid pressurization, fluid warming, fluid deficit monitoring (including flow-based and weight-based), suction, fluid collection, and fluid evacuation (including indirect-to-drain and direct-to-drain options). The systems can be configured based on the surgical environment (e.g., operating room or physician office) as well as other user needs and/or preferences.

An enema includes a liquid in a dispenser having a bottle, a nozzle attached to the bottle, and a valve. The valve may be a membrane having a slit and a thickness of at most 0.90 mm. The valve may be attached to the bottle or it may be attached to the nozzle. The enema can be administered more easily, with a lower amount of force. A method of bowel cleansing includes inserting the enema into a rectum and applying a compression force to the enema bottle.

A surgical apparatus for use by a surgeon can include a tray and a plurality of surgical instruments. The tray can have a plurality of structures located on an upper side of the tray for receiving the plurality of surgical instruments. The tray can receive a separate control unit. The tray can also have a fluid reservoir receiver for receiving a bottle or container of fluid, such as balanced salt solution. The fluid reservoir receiver can include one or more features, including, a spike, an air vent, and a light. A separate container can be used to place the bottle or container of fluid into the fluid reservoir receiver on the tray. This separate container can include a collapsible section.

A fluid ejection device includes a fluid ejection unit that ejects a fluid, an ejection control unit that receives a fluid ejection command input, and controls the ejection of the fluid from the fluid ejection unit, a fluid container that accommodates the fluid to be supplied to the fluid ejection unit; and a supply control unit that controls the supply of the fluid from the fluid container to the fluid ejection unit, and determines whether the fluid can be supplied to the fluid ejection unit from the fluid container. When the supply control unit determines that the fluid cannot be supplied even after the ejection command input is received, and then a predetermined amount of time has elapsed, the ejection control unit reports a fault, and prohibits the fluid ejection unit from ejecting the fluid until the ejection command input is canceled.

A method for cerebral cooling is described using a cooling assembly, which includes first and second elongate tubular members adapted for insertion into a nasal cavity of a patient through the patient's nostrils. The elongate tubular members each have a proximal end, a distal end, a lumen extending therebetween, and a plurality of ports in fluid communication with the lumen. The cooling assembly also includes a manifold and a reservoir, which contains a pressurized fluid that includes a propellant having a boiling point less than 22 C. The elongate tubular members are inserted into the nasal cavity through the patient's nostrils and pressurized fluid is delivered onto a surface of the nasal cavity by infusing the pressurized fluid from the reservoir through the manifold, into the lumens and through the plurality of ports of the first and second elongate tubular members.

The utility model aims at an intimate cleanser, particularly an intimate douche (500) comprising a bag (100), and a fixed and/or threadable applicator nozzle (200), in which the folding bag (100) presents a new practical and anatomic design, resulting in a portable and disposable intimate douche (500). Additionally, the utility model provides irrigation of the pelvic cavity through the flow of content, preferably improved water expelled from the intimate douche (500) into the female and/or male pelvic cavity in order to assist in hygiene, cleansing, treating, odorizing, gut flora replacement, lubrication and/or anesthesia of such cavities.

A fluid infusion system includes an air pump connected to an accumulator tank to produce pressurized air that is stored in the accumulator tank. The system can include one or more fluid bag chambers wherein each fluid bag chamber includes an inflatable bladder positioned inside the fluid bag chamber to apply pressure on the fluid bag supported inside the chamber. The fluid bag can be connected by a tube set to deliver fluid from the fluid bag to a surgical tool at a surgical site. The fluid can, for example, be irrigation fluid or distention fluid. The system can include a controller connected to the pump to control the pump to produce the pressurized air and an adjustable pressure regulator can be connected between the accumulator tank and the inflatable bladder to control the pressure of air delivered to the inflatable bladder and the pressure that the fluid is delivered to the surgical tool. A pressure sensor can be connected between the adjustable pressure regulator and the inflatable bladder to measure the air pressure delivered to the inflatable bladder and send the air pressure measurements to the controller. The controller can configure the system display to show the air pressure measured by the pressure sensor.

An enema includes a liquid in a dispenser having a bottle, a nozzle attached to the bottle, and a valve. The valve may be a membrane having a slit and a thickness of at most 0.90 mm. The valve may be attached to the bottle or it may be attached to the nozzle. The enema can be administered more easily, with a lower amount of force. A method of bowel cleansing includes inserting the enema into a rectum and applying a compression force to the enema bottle.

Systems and methods of efficaciously washing body cavities, specifically including the nasal cavity, wherein a fluid flow is governed in at least one of degree and direction of issuance. Governing of the degree of fluid flow can involve an applicator that is affixable to a fluid source, wherein the applicator can variably constrain the degree of fluid flow being issued. Governing of the direction of issuance can involve the applicator, when affixed to the fluid source, issuing the fluid flow in a specific direction, relative to the fluid source, and an indicator of the fluid source's general orientation relative to vertical.

Provided are a solution preparation device and a nasal irrigator. The solution preparation device includes a casing, a flow valve, an on-off valve, a top cover, a first mixer, and a second mixer. A partition is provided in the casing and divides a receiving space into a first chamber and a second chamber. The partition is provided with a mixing channel communicated with the first and second chambers, and a part of the bottom plate corresponding to the second chamber is provided with a discharge channel. The flow valve is arranged in the mixing channel, and the on-off valve is arranged in the discharge channel. Each of the first and second mixers is provided at the top cover, and extends into a respective one of the first and second chambers when the top cover is connected to the casing.
