The “Dental Unit Flush Adaptor” was an idea that I came up with while running a dental equipment repair business in Florida. After eight years and thousands of service calls in dental offices both in Florida and now in Michigan, I began to realize that one of the single biggest problems that all dental office staff deals with is maintaining the water lines in all of the equipment used to treat patients. The problem of “bio-film” growth in the dental industry has been an issue that has been dealt with using water filters, special “bio-free” tubing and tablets that can be put into the water bottles that feed these dental units when they are not connected to city water. These have all been proven effective but the problem that is still not solved is the proper “flushing” of the water lines in all the equipment that is used to treat patients within the dental operatory. All major manufacturers of dental delivery units have a “flush valve” built into the delivery unit. The biggest problem with the “flush valve” that is built into the delivery unit is that most office staff and dental assistants do not utilize this feature to flush the lines properly and they find this procedure to be bothersome. I wanted to design a device that would be more effective at reducing the bio-film and would be easier for office staff to use on a regular basis.
The “Dental Unit Flush Adaptor” was designed to simplify the process of flushing the water lines on all dental units. Most major brand manufactured dental units contain a water flush button/toggle valve that will activate the water flush that basically pushes old water out of the hand piece tubing in the delivery unit and replaces this area of the tubing with fresh water. The biggest two problems that I have seen in all the years of doing this service work is that this flush button/toggle valve is hardly ever used the way the dental equipment manufacturers intended, and the water flush itself is under minimal pressure. My adapter would allow all of the hand piece tubings on the dental unit to be flushed at once, along with the water lines going to the air/water syringes. The tubing being flushed connects to the adaptor I designed and this adaptor is connected to the vacuum/suction line on the bottom of the adaptor. This allows the water to be flushed through the system under much higher pressure, which performs a more thorough flushing and allows all the lines to be flushed at once. This adaptor will also make this process for all office staff, including dental assistants and hygienists to perform the proper water line maintenance in the rooms they are working out of. The other major advantage to my invention, by incorporating the vacuum line into this process, it can also evacuate all the water from the hand piece tubings which will prevent the bio-film growth to even begin. This is a big advantage for offices that don't use certain hand piece tubings regularly.

The Dental Unit Flush Adaptor was designed to aid in the flushing of the water lines on the hand piece tubings on any dental delivery unit made by any manufacturer in the world. This manifold as I have designed it, will also allow the user to attach any Cavitron, or any other brand of sonic hygiene cleaning instruments to the tubings as well. All dental hand piece tubings in the United States and throughout the world are a standard of width that will fit into the ½ inch ID tubings that will go onto the hose barbs (3) in the drawings. The ⅛ inch ID tubings that will attach to the hose barbs (4) will be used to insert the tips of any brand/manufacturer of Air/Water syringes. The bottom tube of the manifold (5) is 7/16 inches OD. This is also a standard size throughout the entire dental industry for the straws that fit into the vacuum valves that exist in every dental operatory to provide suction during procedures. When my device is put into use, there will be hoses attached to the hose barbs (3) and (4) from the drawing. The bottom 7/16 inch OD tube (5) coming of the bottom of the manifold will be inserted into any vacuum valve that is the standard HVE size within the dental industry. Once this device is inserted into the HVE vacuum valve within the dental operatory, the vacuum valve itself will be opened. At this point the manifold tube itself (1) will have a constant vacuum pressure coming from the tubes attached to the hose barbs (3) and (4). With my manifold inserted into HVE vacuum valve, with the valve open and the hoses attached to the hose barbs, the operator of this device can then insert the end of the hand piece tubings from the dental unit itself into the open end of the tubings attached to the hose barbs (3). The next step will be to take both of the Air/Water syringes with the syringe tips attached to the Air/Water syringe itself and insert those syringe tips into the ⅛ inch ID tubings that are attached to the manifold (4). Once these connections are made, the operator of the device can use the “flush” button/toggle that is on all dental units to activate the water flow to the end of the hand piece tubing. This device will allow the operator to flush the water system using the vacuum system within the dental operatory. This device is also designed so that all the hand piece tubings and Air/Water syringes can be flushed at once.
