A-dec Syringe Tip Your A-dec syringe is packaged with two specially designed A-dec syringe tips. These tips have three locking grooves which hold the tip in place when properly installed and prevent ejection of the tip during use. A-dec tips have the distinguishing mark of the A-dec “a” printed on them. Figure 3. Distinguishing Mark

WARNING Use only A-dec syringe tips in A-dec syringes. A-dec syringe tips have been engineered and manufactured for use with A-dec syringes. Using syringe tips manufactured by a company other than A-dec may result in syringe tip ejection. Tip ejection may result in ingestion or aspiration of the tip, requiring immediate medical attention.

A-dec Syringes Instructions for Use

Install the Syringe Tip The tip installation is the same for both the standard and locking retainer assemblies. 1. Push the syringe tip into the syringe tip retainer assembly until you feel two clicks. WARNING If you do not feel two clicks as you install the syringe tip, do not use the syringe. The O-rings inside the syringe tip retainer assembly are damaged and may allow the syringe tip to be ejected. Replace the O-rings before using the syringe. Figure 4. Install the Tip

Incomplete Tip Installation (groove showing)

Complete Installation (no groove showing)

2. Point the syringe at the floor and press the air button several times to be sure the tip is properly installed. TIP Remove the syringe tip by pulling the tip straight out of the syringe.

Syringe Tip Retainer Assembly A-dec syringes are factory equipped with a non-locking syringe tip retainer assembly. A locking retainer assembly is optional. Figure 5. Syringe Non-Locking and Locking Tip Retainer Assemblies

Non-locking Retainer

Locking Retainer

Non-Locking Retainer Assembly The non-locking syringe tip retainer has a smooth exterior surface and allows you to easily remove and install the syringe tip. The non-locking retainer assembly is not appropriate for use as a cheek retractor because it allows the syringe tip to rotate.

NOTE

85.0680.00 Rev AE



Locking Retainer Assembly The locking retainer has a hex-shaped exterior that allows the nut to be tightened, preventing the tip from easily rotating. The tip can then be used for cheek retraction.

Restrict The Tip Rotation Your syringe tip rotates to spray in different directions. However, if you use your syringe tip for cheek retraction and you have the hex-shaped retainer nut, you may adjust the nut so the tip does not rotate easily. 1. Install the syringe tip. See “Install the Syringe Tip” on page 4. 2. Use the plastic wrench provided with the hex nut to tighten the hex nut. 3. Ensure that the tip does not rotate easily. Tightening a hex retainer nut on an improperly installed syringe tip crushes the internal collet, making removal of the syringe tip difficult and installation of a new tip impossible.

CAUTION

TIP Remove the tip by turning the hex nut 1/4 turn counterclockwise and pulling the tip

straight out of the syringe.

Quick-Disconnect Syringe Terminal An A-dec quick-disconnect terminal allows you to remove a syringe from the delivery system without turning the system off. Figure 6. A-dec Quick-Disconnect Syringe Terminals

To Disconnect the Syringe 1. Turn off the Master Toggle. 2. Press the syringe air and water buttons to relieve the system air and water pressure. 3. Unscrew the syringe handle until the syringe head separates from the syringe terminal. When the syringe is disconnected, any water remaining in the syringe head drips out. CAUTION Before disconnecting the syringe on units without a quick-disconnect syringe terminal, remove the self-contained water bottle. If the water bottle is located above the height of the syringe, water can drain out of the tubing.

A-dec Syringes Instructions for Use

A-dec Warm Water Syringes An A-dec warm water syringe delivers warm water to the oral cavity, eliminating the discomfort that can be caused by spraying cold water on sensitive tissues. The A-dec 300® and the A-dec 500® delivery systems and assistant’s instrumentation use syringe tubing heated by resistance wiring and have five temperature settings. Cascade® and older model delivery systems and post boxes use an in-line water heater and syringe tubing heated by resistance wiring. The water temperature on a Cascade or older delivery system is not adjustable. For temperature adjustments, see “Temperature” on page 8. Figure 7. In-Line Low Voltage Water Heater for Cascade and Older Delivery Systems

Asepsis All syringe tips are considered critical items and must be heat sterilized after each use. A-dec has designed syringes and syringe tips to be autoclavable or heat sterilized. Remove the syringe and syringe tips from the delivery system for sterilization.

Disconnect the Syringe 1. Turn off the Master Toggle. 2. Press the syringe air and water buttons to relieve the system air and water pressure. 3. Unscrew the syringe handle until the syringe head separates from the syringe terminal. When the syringe is disconnected, any water remaining in the syringe head drips out.

Precleaning Preclean the syringe and tips before sterilization. 1. Gently brush the syringe threads with a nylon or brass bristle brush. 2. Remove the tip from the syringe. 3. Immerse the tip in a holding solution until ready for ultrasonic cleaning. 4. Clean the tip ultrasonically, following the ultrasonic manufacturer’s instructions. 5. Purge all cleaning agents from the syringe and tip before sterilization.

85.0680.00 Rev AE



Sterilization Follow these steps to sterilize the syringe and syringe tip: 1. Rinse the syringe and syringe tips in clear water. 2. Flush the tips with isopropyl alcohol or Harvey’s Vapo-Steril. 3. Heat sterilize the syringe and syringe tip using a steam autoclave for at least 4 minutes at a dwell temperature of 273°F (134°C). CAUTION

Sterilizing equipment at higher temperatures reduces the O-ring life-span.

Adjustments A-dec syringes are adjustable for air and water flow. A-dec warm water syringes for the A-dec 300 and A-dec 500 products also have a temperature adjustment.

Air and Water Flow A-dec uses three different methods to adjust syringe air and water flow. Use the table below to identify the location and method of adjustment for your A-dec delivery system or assistant’s instrumentation. Table 1. Location and Methods of Flow Control

Adjust the Flow With a Pinch Valve 1. Turn the adjustment screw for the water tubing clockwise to reduce the water flow, or counterclockwise to increase the flow (see Figure 8). 2. Turn the adjustment screw for the air tubing clockwise to reduce the air flow, or to counterclockwise to increase the flow. 3. Press both syringe buttons to test the spray. Figure 8.

Adjust the Flow With a Flow Control Valve 1. Turn the top flow control valve clockwise to decrease water flow or counterclockwise to increase water flow (see Figure 9). 2. Turn the bottom flow control valve to clockwise to decrease air flow or counterclockwise to increase air flow. 3. Press both syringe buttons to test the spray. Figure 9.



Maintenance The syringe is designed to be easily serviced in the operatory. The syringe parts subject to wear under normal use are provided in a syringe repair kit which can be ordered from your authorized A-dec dealer. Proper care and maintenance of your A-dec syringe is critical to ensure the safety of your patients and the reliability of this precision instrument.

Use Only A-dec Silicone Lubricant Use only A-dec Silicone Lubricant to lubricate the syringe button assemblies and the O-rings used in the syringe tip retainer assembly. The use of petroleum-based lubricants (jellies, creams, or lotions) cause the O-rings in the syringe to swell and/or deteriorate, resulting in syringe malfunction or failure.

CAUTION

A-dec Replacement Parts A-dec replacement parts have been precisely designed for your A-dec syringe to ensure that the syringe functions properly. As a means of preventive maintenance, A-dec recommends you replace the two internal O-rings (p/n 035.048.01) and the small O-ring (p/n 034.003.01) in the syringe tip retainer assembly at least once a year. Lubricate the O-rings with A-dec silicone lubricant (p/n 98.0090.01) at the time of replacement. Figure 10. Syringe Retainer Nut Assembly O-Rings
