Protecting Patients While Using A Dental Saliva Ejector...

Posted by , on Oct, 2019

One of the most commonly used pieces of equipment in any dental office is the dental saliva ejector. These devices are carefully designed to provide maximum effectiveness in removing saliva from the patient’s mouth, and they are generally very easy to use and operate. However, there are some habits or methods that dental hygienists and even dentists may use with these types of equipment that can make them potentially dangerous for the patient. This is true with any type of dental saliva ejector , including those that are designed with the best and most effective valves, parts, and disposable ends to prevent cross-contamination. Vacuum Issues It is essential to realize that a dental saliva ejector operates at low pressure to remove liquid from the patient’s mouth. This low pressure in the tube is a result of the vacuum created by the equipment when a saliva ejector is in use. If the patient is asked to close his or her lips around the tip of the device, then this action results in the formation of a partial vacuum around the saliva ejector tip. The tighter the seal, the greater the risk of liquid in the tube backing up through the dental ejector and into the patient’s mouth. While the tip is changed between patients, the system itself is not always cleaned or disinfected, which creates the potential for cross-contamination. Another cause of vacuum problems that can cause cross-contamination when using the saliva ejector is to use both the HVE and the SE at the same time with the patient. Using one or the other option with the patient eliminates this type of risk while not adding noticeable amounts of treatment time for the patient. Be the first to...

Factors To Consider When Choosing A 3 Way Ball Valve...

Posted by , on Jul, 2019

Ball valves are one of the most commonly used valves, offering ease of operation, durability, and performance with just a quarter turn. While many systems use a one way ball valve, which allows flow through the valve from the inlet port to the outlet port only in one direction. The one way ball valve has to be installed in the system in the correct position for the valve to open and operate correctly. The two way ball valve can be installed with either port as the inlet and outlet port, making it a good option or an inline valve to turn on or shut off the flow through a system. Some these valves can also be designed with a right angle, with the external control lever to the top of the valve. A More Advanced Control Option The 3 way ball valve is more complex in design. It can be used to turn the flow of the media in the system on and off as well as to divert the flow between one of two possible outlet ports. It can also be used to combine the flow from two different inlet ports or to alternate the flow. With this versatility, these valves are a way to simplify the controls in any system without needing more than one valve to make the necessary adjustments to the flow. The flow pattern of the 3 way ball valve is an L type or a T pattern. The L shape allows for the media to come in one port and be directed out of either of the other two ports. The flow makes an L shape, which is why this is sometimes called a diverter valve. The T-shape in a 3 way ball valve is used to combine flows from two inlets to a third outlet, but they can also function similar to the L pattern and act as a full diverter valve. Choosing the right ball valve also includes selecting the material for the housing and internal components of the valve, including the seals, seats, and the wetted surface area. Be the first to...
