BioGuard Air / Water Channel Assembly
When the air and water valve is activated, it generates a jet of either air or a mixture of air and water. This can, for example, be used to rinse the distal end of the endoscope optical system with water or air.
The air and water valve also enables various activation modes of the channels, for example to dilate internal organs. This can, for example, be useful in observing or surgical interventions.
Air / Water Valve
Air release valves are a critical part of pressurized piping systems. They help to keep air from accumulating in system high points and can prevent pump failures, corrosion, flow issues, and water hammer or pressure surges.
Air-free piping can save money and energy by reducing the need for mechanical equipment. They also eliminate costly leaks and maintain a steady flow of fluid.
A popular place to find these valves is in water pipelines Air / Water Channel Assembly and sewer force mains. However, they can be found in many other areas as well.
When air enters the valve, it bubbles up and displaces the liquid inside. Once the liquid reaches where it no longer buoys the float, the valve opens and vents the accumulated air into the atmosphere.
This automatic cycle repeats as often as necessary to keep the system air free. It’s especially important to install them at the highest points where air naturally collects in a system, such as upstream of an upstream directional control valve or upstream of a regulating solenoid.
The accumulated air pockets can cause a high-pressure surge or water hammer, which can result in the breakdown of pumps, valves, and pipes, and may damage the entire pipeline. This can cost a lot of money to repair or replace and is a serious safety concern in some industries.
Some older piping systems don’t have automatic air release valves. They may be paired with a combination air/vacuum valve or have a manual shut-off valve.
Generally, these valves have small orifices, making them ideal for applications where air is vented only when needed, such as during filling or startup. They are not always compatible with all types of piping, so you must choose the right size for your application.
In addition, some piping materials can collapse under negative pressure. The resulting air pocket can become very large and could cause problems in the future. In these cases, an automatic air release valve is the best solution. They can quickly vent air, allowing it to be returned to the pipeline during filling or emptying, and they also automatically close as necessary to keep the pipeline system air-free.
Air / Water Adapter
The air / water channel assembly is a cinch to build and can be configured in virtually any color scheme. It is also compatible with all major manufacturers of endoscopes. In addition to being an attractive looking piece of kit, it offers the utmost in patient safety and operational efficiency. The best part is that it’s inexpensive to buy and easy to use. It’s a must have in any lab or hospital laboratory.
Taking a page out of the GI department’s playbook, Boston Scientific has come up with an innovative and user-friendly solution. It consists of two key components: a single-use air/water channel and a proprietary, reusable, and biocompatible resuscitation device. The combination is the only one of its kind on the market. The resuscitation device is a novel medical procedure that can be performed at the point of care, which significantly reduces the risk of complications during procedures while at the same time increasing productivity. The resuscitation device is designed to provide a rapid, effective and low-cost means of treating critical infections. This approach has been proven to reduce the overall incidence of infection while at the same time improving patient outcomes.
Water / Air Adapter
The BioGuard Air / Water Channel assembly is a worthy addition to any endoscope collection. It is a practical, affordable and hygienic way to add liquids to your patient’s fluid mix without snagging and spitting. With its clever design and patented nozzle, this unit is a joy to use and to clean. It also helps prevent clogging and reduces the risk of leaky hoses and leaking fixtures. This unit comes with an extra bushing to make it compatible with most air and water valves on the market.

Water / Water Valve Adapter
An exemplary embodiment of the air/water channel adapter valve includes an air/water cylinder, a button; a valve stem extending through a base; and a water channel positioned longitudinally through the valve stem. The device further includes a toggle switch connected at a proximal end of the valve stem, and the button being connected at a distal end of the valve stem. The button can be depressed to change the flow of air and water through the device.
The proximal end of the button can be molded from any number of thermoplastic or thermoset materials such as polyethylene, polypropylene, or polycarbonate; and the distal end of the button can be a coiled spring made of stainless steel. The coiled spring can fit into an inner cylindrical shape of the base 201, which can be molded from any number of thermoplastic materials such as polyethylene, polypropylene, polycarbonate, or diallyl phthalate; and the valve stem can be molded from any number of thermoplastic and thermoset materials such as polyethylene, polypropylene, and polycarbonate.
A dome cap 203 can be attached to the valve stem 202 by a lock feature 208 molded into the valve stem 202, as illustrated in FIG. 9B. The lock feature 208 can include a seal hub 213 that fits into the proximal end of the central channel of the valve stem. The seal hub can be a hollow interior part or it can be solid. A lock feature component 209 can be a protrusion that extends inwardly around an outer circumference of the button cap, interlocking with the lock feature 208 on the valve stem.
As the dome cap 203 extends out of the first end of the valve stem 202, an abrupt change in diameter creates a catch for the dome cap to interlock with the lock feature 208. Once the dome cap is positioned beyond the catch, the seal hub 213 can then fit into the proximal end of the center channel of the valve stem, allowing the valve stem to fluidly connect to the water channel.
The air/water cylinder can also have a plurality of locking tabs 215 that extend downwardly from the distal end of the valve base 201. These locking tabs can be inserted into a plurality of apertures (not shown) formed in the proximal end of the air/water cylinder. The exemplary embodiment of the valve base 201 can include vertically protruding guide elements 216, such as mold snap features, that help align the valve base 201 onto the air/water cylinder. The valve base can further include a connecting portion 212 that over-molds into the connecting tabs 215.
