Microwaves and Static Electricity

Lizzy731 started a thread on Children with Diabetes (click here for the thread) where she shares her experience that the PDM lost the communication link to the OmniPod. She was administering a bolus while standing very close to a microwave oven in use. She called customer service and they helped isolate the microwave as the most possible cause. After changing the pod, everything was OK.

Another user shared an experience that static electricity can also be a potential cause of failure. They shared the experience that their child was sliding with the pod located on the child's backside when it stopped working. Lots of static electricity on slides!

FAQs-How much does the OmniPod cost?

The answer is located on the official OmniPod FAQ website.

FAQs-Is the OmniPod available in my area?

Go to this link on the OmniPod website to find out if the OmniPod is available in your area.

FAQs-Can I download data from the OmniPod?

The PDM (Personal Diabetes Manager) has an IR (infrared port) that can be used to download data. Comments in other forums report that the software can be obtained by contacting Insulet directly.


As I browse the diabetes blogs and forums and read the comments, there seems to be a lot of people asking the same questions about the OmniPod. Many of the answers to the questions can be found in the FAQs on the official OmniPod website. If you don't see the answer to your question there, just post a comment here or at the OmniPod group on tudiabetes.com.

As new questions are asked, look for the answer on this site. Just click on the FAQs label/tag to find the answers.

8 Month's Later

The blogger behind DiabetesMine.com just posted a summary of her first eight month's of OmniPod use. What does she think?
Well it's about 8 months, maybe almost 9, since I started pumping insulin using the tubeless Omnipod system. Many of you have sent queries wondering whether I'm still on it, and still happy? The answers are: yes and yes.

We all know there are no miracle cures. But I can honestly say that 1) pumping has changed my life, and 2) there's no way I would be here right now, enjoying pumping, if it weren't for the no-strings-on-me option (currently only offered by Insulet).

Omnipod User Group on tudiabetes.com

I just started a new group at tudiabetes.com for Omnipod users to allow each of us to discuss and share our experiences of using the Omnipod.

Freescale Microcontrollers Control the Omnipod

Freescale Semiconductor has posted a customer case study on their website that provides a little insight into what makes the Omnipod and the PDM work.
The OmniPod is a small, lightweight, self-adhesive pod that delivers insulin, according to a person's pre-programmed personal basal rates and bolus dosages. The Pod also features automated cannula insertion for reduced insertion errors and increased consistency and comfort. Since the patient is automatically injected once the Pod is adhered to the skin, the anxiety and pain that often come with the traditional daily insulin injections or a conventional insulin pump are no longer a factor. Additionally, the Pod is small, about the size of a walnut, and can be worn under clothing where conventional pumps have tubing attached to a pager-like device that is not easy to conceal. The user changes the Pod about every three days.

The PDM, the wireless, intuitive, hand-held device that programs the OmniPod with customized insulin delivery instructions and monitors the OmniPod's operation, contains a fully integrated blood glucose meter, and automatically stores patient records.

To meet the price and performance requirements of this system, Insulet looked to Freescale Semiconductor to develop a combination of standard microcontrollers (MCUs) with custom RF silicon. "No one else could match both the RF technology at the required price points," said Luis Malavé, senior vice president of research, development and engineering at Insulet. "Additionally, Freescale is one of the few companies that had the technology to make these devices into a single package solution."

The OmniPod uses the MC9S08RX32A which has two die inside a single package—a custom RF integrated circuit and a standard MC9S08GB60A 8-bit MCU. The PDM uses the Freescale Dragonball microprocessor, the brains of the wireless device, as well as the same MC9S08RX32A, enabling a true wireless connection.

The MCUs manage the flow of insulin and the MCU and RF IC interface with the handheld controller (the PDM) to relay information, manage and monitor the flow of insulin. Additionally, the devices offer safety features built into the software.

A microcontroller (MCU) is similar to a microprocessor found inside your computers from Intel and AMD. Microcontrollers are much less expensive and have everything needed to function (program storage.. like the hard drive, RAM, communication circuits (like USB, serial ports, ethernet) combined on one tiny chip.

The PDM uses 2 microcontrollers: a 32-bit microcontroller to control the unit and an 8-bit microcontroller with a separate RF (Radio Frequency) chip that communicates wirelessly with the pod. Each pod has the same 8-bit microcontroller combined with a RF chip to control the pump, the needle to insert the cannula, the speaker to alarm the user, and to communicate with the PDM.

If you are using the Omnipod, you are walking around with three powerful computers. Each of them are over a million times more powerful than the very first computer introduced around 1940 that filled an entire room.

Changing My First Pod

This afternoon, I heard a beeping sound. It took me a little while to find that the sound was coming from the pod installed on my stomach. I didn't realize the pod also contained a speaker. Cool!  I turned on the PDM, which also started beeping at me, and learned that the alarm was warning me that the pod would need to be replaced in a few hours.

That evening, the pod beeped at me again telling me three days was up and it was time to install a new pod. I slowly started peeling the adhesive tape away from my skin. There was some pain as I peeled it away. A small price to pay for only having to give myself one shot every three days. (Note to Self: Keep the pod away from places with lots of hair). I was surprised to see that the cannula was 9mm long.

To install a new pod, I just followed the instructions on the PDM. With an alcohol prep pad, I cleaned a new site on the other side of my stomach. I then filled the pod with 200 units of insulin, pushed next on the PDM to prime the pod, removed the adhesive backing on the pod, placed the pod on my stomach, pushed next again on the PDM to activate the pod, waited a few seconds, and "pop!" the cannula was inserted and pumping insulin again.

See how it works on Omnipod's website.

Again, Youtube user cyclicpitcher has more guts than me in showing the world his abdomen. Check out his video on removing the pod.

The First Few Days

This is so exciting! I haven't given myself a shot for 2 days. If my blood sugar is high, it is so incredibly easy to give myself a correction bolus to quickly get it back down. My morning blood sugar level has been consistently at 100. I haven't seen that for a long time.

Training with Omnipod's CDE

Omnipod's CDE (Certified Diabetes Educator) came this morning to train me on using the Omnipod.  We spent just over an hour ensuring the PDM was setup correctly, teaching me about how/why each setting is used, and operating the PDM and pods.  Together we filled a pod with insulin, primed the pod, prepared the site on my stomach, applied the pod to the site, and then activated the pod.  A few seconds later, I heard a click and felt the needle place the soft cannula (tube) into my skin.  The experience felt the same as lancing my finger tip for blood sugar testing or like most of the insulin injections I give myself.  I say most because sometimes my insulin injections really sting!  Woohoo!!  No more shots 4+ times each day!!  Life is good.

Youtube user cyclicpitcher has more courage than I do showing how the Omnipod is installed on his stomach. I will let him show you how to setup and install a pod.
