The present invention discloses a positive-pressure double-nozzle nasal cavity cleaner featuring double pressure protection, and relates to the technical field of health care. The nasal cavity cleaner consists of a nose washing end, an upper shell, a core module, a control module, a lower shell, a liquid reservoir and a waste reservoir, wherein the nose washing end is rotatably connected to a top portion of the upper shell, and the nose washing end consists of a silicone washing nozzle, a silicone backflow nozzle and a rotary connecting base. The nasal cavity cleaner uses positive pressure and automatic pressure relief structures to obtain safe and constant air pressure, and then presses normal saline into the nasal cavity to clean the nasal cavity, so that pressure in the nasal cavity is small and stable during cleaning, which prevents damage to the nasal cavity and ear canal, thus being safer to use. Besides, deeper areas can be washed, nasal scabs in the nasal cavity can be moistened and removed, harmful substances such as dust in the nasal cavity can be removed, the nasal cavity can be moistened, and normal swing of nasal cilia can be recovered, which are helpful in treating rhinitis and preventing the onset of allergic rhinitis.

Apparatus, system and method for providing pressurized infusion of liquids and, more particularly, providing a stable and pressurized flow of fluid to the eye during surgery. Aspiration fluid may be received via an aspiration line at a first peristaltic pump, where aspiration fluid is transferred to a Venturi tank reservoir coupled to a second peristaltic pump. Fluid from a fluid source is provided via a third peristaltic pump to a pressurized infusion tank. A determination is made if the pressure in the pressurized infusion tank is at a predetermined level, where fluid may be transferred from the pressurized infusion tank to an irrigation line when pressure in the pressurized infusion tank is determined to be at the predetermined level. Alternate activation of a plurality of aspiration and irrigation lines are also provided.

A nasal irrigation diagnostic assembly comprising an irrigation device including a fluid collection portion structured to retain a biological sample, in the form of waste solution from the nasal cavity resulting from irrigation. A detection member disposed on said irrigation device is exposed to the biological sample and is structured to determine the existence of at least one analyte within the biological sample of the waste solution. The detection member comprises a plurality of detection zones individually structured to analyze the biological sample upon engagement therewith, wherein said plurality of zones include at least a reaction zone and a detection zone, which respectively include reagents cooperatively and collectively formulated to detect the existence of the at least one analyte within biological sample of the waste solution. A control zone may also be included to indicate the intended operability of at least the detection member.

A container for holding a liquid, in particular an infusion liquid or irrigating liquid, comprising a liquid phase containing the liquid and a gas phase, wherein, in the operating position, a liquid opening is formed in the lower region of the container and wherein the container has a gas opening. The gas opening is formed by a gas pipe which is inseparably connected to the container and has a first gas pipe end and a second gas pipe end. The first gas pipe end extends into the gas phase of the container and is provided with a closure. The second gas pipe end leads to the outside of the container.

A device including a gas pressure device providing a variable initial pressure (P.sub.A), a fluid container providing a fluid for rinsing an eye, the fluid container being connected to a surgical handpiece to deliver the fluid into the eye at an irrigation pressure (P.sub.I) predeterminable by the surgeon. The fluid container is connected to a connecting element on a side which is upper in the operating position, and the fluid container communicates with a gas phase container via a mandrel of the connecting element on a lower side of the gas phase container, and the gas phase container and/or the fluid container exhibit(s) a gas phase and the gas phase communicates with the gas pressure device via the connecting element or a fluid container line, and the irrigation pressure (P.sub.I) of the surgical handpiece is adjustable via the variable initial pressure (P.sub.A) of the gas pressure device.

A medical spraying device and method for irrigating a wound, in particular lavage system, having a liquid reservoir for a medical irrigation liquid or a connection for such a liquid reservoir, and a compressed gas reservoir. The compressed gas reservoir is connected or connectable via a pressure line to the liquid reservoir, such that the irrigation liquid can be pushed by the gas pressure of the compressed gas reservoir acting on the irrigation liquid through a nozzle in order to produce a spray cone. A pressure reduction valve is arranged in the pressure line and limits the gas pressure acting in the liquid reservoir on the irrigation liquid. The device and method produce a spray cone of a medical irrigation liquid in which a gas pressure is limited using a pressure reduction valve, wherein the gas pressure limited by the pressure reduction valve is conveyed through a pressure line to a liquid reservoir of the medical irrigation liquid. The irrigation liquid is pushed out from the liquid reservoir through a nozzle by means of the gas pressure, wherein the spray cone is produced in that the irrigation liquid flows through the nozzle.

A portable irrigation system comprising a reservoir for an irrigating liquid, a probe for arrangement in a user, an electrical system, a control unit for controlling the transfer of irrigation liquid and tubing providing fluid communication between said reservoir, control unit and probe.
