Using Your CADD-Legacy Plus Pump

This information describes how to use your CADD Legacy Plus® pump. This small, battery operated pump can be used to deliver fluids, medication, and chemotherapy into a vein. The pump can do this continuously (continuous mode) or at regular intervals (intermittent mode). This information describes only the continuous mode, which is what you will use.

Beginning Your Treatment

Your nurse will teach you and a family member or friend how to use the pump before you begin treatment. You’ll spend approximately 2 hours at your first visit so that you’ll have enough time to learn about your treatment and get comfortable with the pump. After you have worked with the pump and feel you can manage safely at home, your nurse will start your treatment. Your next visits will be shorter. During those visits your nurse will prepare your chemotherapy and program your pump according to your doctor’s orders.

While receiving treatment by this pump, you will be responsible for:

  • Making sure the pump is working
  • Stopping the infusion, if necessary
  • Observing your IV or port site
  • Watching for side effects of your treatment
  • Returning the pump and used equipment promptly to your nurse

Using the Pump

How to stop the pump

Press and hold the STOP/START button until 3 dashes appear on the display. After the third dash appears, release the STOP/START button. The word “STOPPED” will appear on the display.

How to start the pump

Press and hold the STOP/START button until 3 dashes disappear one by one. All of the programmed modes will appear one after the other for you to review. The word “STOP” will disappear from the display and “RUN” [RES VOL] will appear. This shows that the pump is running and indicates how much medication is left.

Turning the pump off

While the pump is stopped, you can turn it off by pressing and holding down the ON/OFF button. When 3 dashes appear, release the ON/OFF button.


The pump has several alarms that will alert you to any problems. An alarm will stop once the problem is fixed. You can also silence the alarm for 2 minutes by pressing the STOP/START button.


When the batteries in the pump get low, a two-tone beep will sound every 5 minutes. Each beep is 3 seconds long. Also, “LOW BATT” will appear on the display. The pump will still work but you must replace the batteries.

If the batteries are completely dead, you will hear a constant two-tone beep. The words “BATTERY DEPLETED” will appear on the display. You must replace the batteries with 2 AA alkaline batteries. The pump has an AC adapter that you can plug into the wall, but the batteries are needed even when you plug it in.

To replace the batteries, press and hold the STOP/START button until you see 3 dashes on the display. After the third dash appears, release the STOP/START button. The word “STOPPED” will appear on the display. Slide open the battery cover on the back of the pump by pushing down on the arrow. Remove the used batteries. Match the polarity markings (+ and -) on the batteries with those inside the battery slot. Insert the batteries over the top of the battery strap. If you put the batteries in backwards, the display will be blank. When they are inserted correctly, the pump will beep. The pump will then go through an electronic self-test. It will beep 6 times at the end of the power up sequence. Replace the cover by sliding it over the batteries. Press and hold the STOP/START button to restart the pump.

Reservoir volume low

When there are 5 mL (5 milliliters) of chemotherapy left in the reservoir you will hear beeps. The words “RES VOL LOW” will appear on the display. The pump will continue to beep each time the amount of medicine decreases by 1 mL. These beeps should coincide with your next scheduled visit with your nurse. If your appointment is not scheduled for the day the beeping starts, call your nurse. You will need to make arrangements to have your chemotherapy replaced.

Reservoir volume empty

When the pump sense that there is no chemotherapy left in the reservoir, you will hear a continuous two-tone alarm. The words “RESERVOIR VOLUME EMPTY” will appear on the display. To silence the alarm, press the STOP/START button. Call your nurse so that a new medication cassette can be prepared or the pump can be discontinued. Do not attempt to restart the pump until you have seen your nurse.

Air in line detected

A two-tone alarm and “AIR IN LINE DETECTED” on the display usually means there is air in the tubing. It could also mean that the tubing is not fully threaded through the air detector. Press STOP/START to silence the alarm and call your nurse.


A two-tone alarm and “ERROR” on the display means that there is a problem with the pump. Clamp the tubing and call your nurse. Press the STOP/START button to silence the alarm for 2 minutes.

High pressure

A two-tone alarm and “HIGH PRESSURE” on the display means the tubing is kinked or pinched. Press the STOP/START button to silence the alarm for 2 minutes. Check for anything that may be pinching or kinking the tubing. If you have removed the cause of the high pressure, start the pump. If the alarm continues, contact your nurse.

Service due

A two-tone alarm and “SERVICE DUE” means that the pump is scheduled for service. Press the STOP/START button to silence the alarm. The pump is still working, but you must tell your nurse.

Upstream occlusion

A two tone alarm and “UPSTREAM OCCLUSION” means that your chemotherapy is not flowing from the reservoir to the pump. To silence the alarm, press the STOP/START button. Check for a kink in the tubing or a closed clamp between the reservoir and the pump. If the alarm continues, call your nurse. Once you have removed the kink or occlusion, restart the pump.


Three beeps every 5 minutes and “STOPPED” means that the pump is in the stopped mode.

Observing your IV site

Your treatment is given into a catheter or port that goes into a vein. If you are getting treatment through a port, you must check it twice a day to make sure the needle is in place. Do this by pressing on the needle gently. You should feel it touch the back of the port.

Whether you have a catheter or a port, you must check for:

  • Leaking of chemotherapy on your skin around where the needle goes into your body
  • Signs of infection, such as
    • Redness
    • Pain
    • Swelling
    • Drainage

Frequently asked questions

Can I keep doing my usual activities while I have the pump?

The pump will not affect most normal activities, including sexual activity. It is lightweight and easily hidden in a pouch that can be worn on a belt or shoulder strap. At bedtime, place the pump on your bedside table.

Can I get the pump wet?

The pump is water-resistant but not waterproof. Do not take a shower with the pump because it’s too easy to get both your bandage and pump wet. Take a bath instead. When bathing, place the pump in a plastic ZipLoc® bag outside of the tub. If you accidentally drop it in the water, pick it up quickly, dry it off with a towel, and call your nurse. You cannot go swimming while you have the pump.

How often will I need to change the batteries?

This depends on the volume of chemotherapy and the rate at which it is given. When the pump is in the continuous mode, the batteries will last about 7 days. Always carry 2 extra AA batteries with you.

Discontinuing the Pump

Handling chemotherapy

Some chemotherapy drugs may cause burning if they touch the skin or eyes. To avoid this, you must follow these guidelines when you discontinue the pump.

  • Prepare a clean work area; do not use a bathroom.
  • Keep food and other items away from the work area. This is to prevent them from coming in contact with the chemotherapy.
  • Wash your hands thoroughly before and after handling the drugs.
  • Wear gloves when you disconnect the pump and remove the needle.
  • Do not allow pregnant or nursing women to handle the drugs.
  • If chemotherapy splashes in your eyes, immediately rinse them with running water. Keep the water flowing over your open eyes for 10 to 15 minutes. Call your doctor or nurse to ask for more instructions. Your eyes may need to be examined.

If your chemotherapy spills

  • Put on disposable gloves
  • Soak up the spill with disposable towels
  • Clean the area of the spill with a disinfectant wipe that contains bleach
  • Clean again with soap and water and paper towels
  • Place all supplies used to clean the spill in a plastic bag and seal it before you put it in the trash
  • When you throw things out you must make sure that people and pets will not come into contact with the chemotherapy
  • Put the equipment in a heavy plastic or metal container that can be well-sealed. Be sure to separate the container from those to be recycled

If your chemotherapy gets on your clothing or linens

  • Put on disposable gloves
  • Make sure that the items with the chemotherapy do not touch any part of your body
  • Place the items with the chemotherapy on them in the washing machine and wash as usual
  • Do not wash any other laundry with chemotherapy-soiled items
