How To Get Started Using Your Injector

When your Madajet injector arrives, it’s best to take a moment to familiarize yourself with the various parts of the injector first. You can do this by examining the diagram on page 6A of the Instruction Manual or on this page.

Madajet Diagram

The Madajet comes packed in a non-sterile sealed plastic bag. Although it has been thoroughly disinfected with MadaCide-FD (#2527), you may choose to autoclave it for its first use. Please check the manufacturers directions for your autoclave.

The following are general directions for steam autoclaving the Madajet:

• Open the plastic wrapping on the injector and unscrew head assembly and pyrex fill chamber from the body. Do not remove the Extenda Tip.

• Each component, including the MadaJet injector body, is to be wrapped separately in sterilization pouches and put in the autoclave. Be sure to pull the cocking lever down (until it clicks) on the MadaJet injector body prior to placing it in its’ sterilization pouch.

• The Madajet XL requires steam autoclaving by one of the following two methods:

1. Steam Pre-Vacuum Method
- Temperature: 132 C (270 F) Exposure Time: 4.0 Minutes

2. 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.

It’s important to carefully review the instructional materials provided in the package with your injector. They not only help you to get the best use of your MadaJet but also include certain cautionary warnings to help you avoid unsafe practices.

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 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.

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)

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

Mada Ultrasonic Cleaner

The Mada Digital Ultrasonic cleaner (item# 2310) is designed to 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.

Cleaning And Sterilizing Your Injector

• 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.

Process For Daily Ultrasonic Cleaning

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.

Repair And Annual ServiceDownload Service Form

Even though the MadaJet injector can stand up to rigorous use, it must be routinely serviced by the manufacturer to remain in good condition.

Approximately one year after the first use of your injector, it should be returned to the manufacturer so that all parts can be inspected and worn rubber seals can be replaced. (See "Submitting a Service Request" below) Since this service may require 2-4 weeks, you will need to prepare to be without your injector for that period of time.
