• WHAT TO DO BEFORE AND AFTER USE
BEGIN DAILY USE:
1. Unwrap parts using sterile gloves.
2. Insert the glass chamber (#2306) onto head assembly and transfer 3 cc of 2% Lidocaine with your syringe from a carpule or multi-dose vial into the chamber* (see illustration A). (Hint: for a better seal between the fill chamber and head assembly "wet" the base of the chamber with sterile water or anesthetic prior to insertion into the head.) * Capacity of fill chamber is 6cc.
3. Insert head assembly with glass chamber gently back into the body keeping the instrument in a vertical position with the head pointing down.
4. Prime the instrument by gently pushing the body into the head assembly up and down on the shaft. A small amount of liquid will be expressed from the nozzle. This indicates that there are no air bubbles in the injection stream. If you do not see solution spray from the nozzle when you prime the instrument, check that the cocking lever is not already cocked. Screw the head assembly back on the body, cock and fire 1-2 times.
5. Place MadaJet into the stainless steel stand after you have put approximately 30 cc of MadaCide-FD (#2527) into the stand. You are now ready to use your MadaJet. After use on each patient, place it back into the stand with the head immersed in 30 cc of the MadaCide-FD disinfecting solution for no less than 6 minutes.
CAUTION: DO NOT LAY UNIT FLAT.
AFTER DAILY USE:
1. Unscrew head assembly and pour out any unused anesthetic solution. Note that most anesthetic solutions will cause a brown discoloration of metal parts if any remnants are allowed to remain in the instrument for more than 1-2 days. Therefore, always pour out any remaining anesthetic solutions each evening.
2. Fill the head assembly with sterile or distilled water and prime the head 2-3 times before autoclaving the entire unit. (For more details on autoclaving the Madajet, see "Sterilizing with Steam Autoclave" below)
3. If you do not plan to autoclave the injector, pour 3 cc of MadaCide-FD (#2527) solution into the head assembly and prime 2-3 times to clear out any anesthetic or medication solution. With the remaining MadaCide-FD solution left in the head assembly, place unit into the MadaJet stand and leave overnight or until next use.
Note: It is recommended that at the end of each day of use or at the end of the week of use, you should use the Mada Ultrasonic Cleaner (item# 2310) to thoroughly clean the injector per ultrasonic cleaning instructions.
NEXT USE:
Pour out all remaining MadaCide FD solution and rinse the unit with sterile or distilled water. Prime the head assembly 2-3 times and follow points #2 through #5 "For Daily Use" above.
• CLEANING AND STERILIZING YOUR INJECTOR
DAILY CLEANING OF HEAD ASSEMBLY WITH THE MADA DIGITAL ULTRASONIC CLEANER
The Mada Digital Ultrasonic cleaner (item# 2310) is designed perform a high power cleaning of even the tiniest areas of the head assembly of the injector, keeping it clear of sediments and particles.

When the head of the MadaJet as well as the chamber area are lowered into the cleaner, cavitation causes high powered microjets of liquid to be propelled throughout the bath of cleaning solution thus removing even the most tenacious particles hidden in crevices of the device upon impact.
Not only does ultrasonic cleaning provide a mechanism to blast away hard to remove soils but it also improves the chemical efficiency of the MadaCide (#2527) disinfectant solution. Acoustic cavitation raises the temperature of the liquid which increases the rate of chemical activity of the cleaning solution.
The Mada Ultrasonic Cleaner also cleans your other surgical instruments.

PROCESS FOR DAILY ULTRASONIC CLEANING
• Fill the (Item# 2310) Ultrasonic tank with clean tap water to full (maximum).
• Add 3 ounces of MadaCide-FD (#2527).
• Remove Madajet XL head assembly from Madajet XL body. Remove glass fill chamber (#2306) and metal Weiss sheath (#2525) and place these parts into the (Item #2310-R) rack.
• Place rack into Ultrasonic unit by hanging it with built-in clip on side of Ultrasonic unit Be sure all parts of the head assembly are covered by liquid.
• Place custom Ultrasonic Lid with two holes on top of the Ultrasonic top.
• Insert Madajet XL less head assembly into one of the lid holes.
• Turn Ultrasonic unit on for 10 minutes to provide disinfecting and cleaning action.
• After 10 minutes, remove the Madajet XL body and head assembly and rinse with sterile water.
• If sterilization is required, follow recommended autoclave procedures after using the Ultrasonic unit. If sterilization is not required, assemble the glass fill chamber and metal Weiss sheath onto the Madajet XL head assembly and fill the glass fill chamber with MadaCide-FD. Replace Madajet XL head assembly onto Madajet and store in Madajet XL stand filled with MadaCide-FD (#2527) until ready for next use.
• Before using your Madajet XL again, be sure to empty the MadaCide-FD solution out of the glass fill chamber and flush out with sterile water before introducing the anesthetic solution.
STERILIZING WITH STEAM AUTOCLAVE
The most common and readily available method for sterilizing the Madajet is autoclaving. However, it is not advisable to use a “dry heat” autoclave since it may cause the washers inside the injector to dry out and crack. These parts can likewise be damaged if the injector is frequently chemically sterilized. Steam autoclave tends to yield the best results.
All components of the MadaJet injector must first be thoroughly cleaned and disinfected to achieve maximum sterilization. Although there are some variations in the use of autoclaves, the general guidelines used for sterilizing the MadaJet injector are as follows...
Cock, the injector and unscrew the head assembly and pyrex fill chamber from the body. Do not remove the Extenda Tip. Wrap injector body, head assembly and fill chamber separately and place in the autoclave.
Steam Pre-Vacuum Method
• Temperature: 132 C (270 F) Exposure Time: 4.0 Minutes
Steam Gravity Method
• Temperature: 132 C (270 F) Exposure Time: 15 Minutes
After autoclaving, remove all parts and allow to cool to room temperature before assembling and use. Again, it is important to review recommended directions by the manufacturer of the autoclave.
