New Dexcom 7 has arrived
When I got home last night a surprise was waiting for me. No, not the Harry Potter book -- that was earlier in the weekend.A box from Dexcom was sitting on my porch, the new Dexcom 7 CGMS had arrived. The box contained an updated Receiver, a transmitter, and the new software box including download cable. I didn't get a new recharger, and unfortunately they didn't provide a shorter cable to connect the Dexcom 7 receiver with my OneTouch Ultra meter for synchronizing.
So I read the instruction manual while eating my dinner. Then I plugged the receiver in for a few hours to charge it up. I decided to insert the new sensor around bedtime. And wow that was a lot easier for me. That small change they've made in the sensor needle gauge made the insertion pain feel a lot less for me.
The Dexcom SEVEN transmitter design changed slightly. It now has two small extensions on the back to lock it into the sensor. This much be part of making the system waterproof. This did make it a lot harder to actually lock the transmitter into the sensor. The little piece of plastic left after sensor insertion really just didn't work.
Luckily I have such wonderful stomach muscles (hah!) that I was able to just push the transmitter into place. It was really tough! It'll be interesting to try and remove it in when the sensor is all used up.
I waited until this morning to tell the Dexcom 7 receiver about the new sensor. A lot of people have reported better results if you wait more than 2 hours after insertion of the sensor.
Dexcom has made several small changes to the screen between the Dexcom 3 and the Dexcom 7. All of these improve it greatly. They've replaced the time range on the Dexcom 3 (9:30 AM to 10:30 AM) with just the current time (10:30 AM) in a larger font and 1 Hr in an even larger font. Net result, it's much easier to figure out which screen you're looking at.
They've also changed the screens you use when telling the receiver that a new sensor is available. I think this will mean less confusion between the sensor insertion and sensor removal screens.
I've posted a short (and slightly fuzzy, sorry) video on YouTube that shows some of the differences between the screens. I'll try and most more about differences between the Dexcom 3 and the Dexcom SEVEN tomorrow.
Note: I currently own some shares in Dexcom, I work not to let this influence what I say about the company or its products.

The video does a great job of displaying the differences between the 2. It's great to see that the companies are actually making their products easier and better to use.
Mine came yesterday too - but I'm trying to coax the current sensor through another few days, as the last three crapped out after just 3 or 4.
So later this week I'm hoping to transition over to the Seven.
Bernard,
Looks pretty cool, I can't wait to see your progress with it (and the data you can export from it :-) ).
Cool Blog!
We got our 7 yesterday too. Great to hear of less pain on insertion. (We use lidocaine prilocaine anesthetic cream so I couldn't tell if my daughter noticed)
Had zero trouble with the insertion of the transmitter to the sensor. We'll see if it happens next time.
hope the 7-day longer time frame, waterproof, thinner needle, accuracy rate is noticable
lastly - re next blog entry re 10 visits/yr to doc; met a woman w/type 1 30 yrs. first 15 yrs always got colds many times/yr. Then she started treating every sinle low glucose reading with OJ. one of those oj packs she carried in her purse 24/7. the vitamin c reduced her colds to one or two /yr. fyi.
WOW! What a cool week. Harry Potter, AND new CBGM! Thats the kind of week I love.
:)
Does anyone know if Dexcom reps are offering the Seven System (like the $350 for the original system).. What are they charging new people?
I would love to know..

The price for a new Dexcom 7 with a box of four sensors is, I believe, $640. Each box of sensors is $240.
My advice to anyone thinking about a Dexcom is to get a trial for at least one week first, ideally 2 weeks. You need to see what it means to wear one of these and to change the sensor.
While I've found the Dexcom very useful, it's another gadget to carry around. It also requires calibration several times a day and you must use a OneTouch Ultra for that. All these factors mean that if you don't try it out first, you might just be disappointed by it.
Also remember there are several bloggers who have tried out the Dexcom. You can find a lot of blog posts about the Dexcom using the Diabetes Search Engine. And you can see my photos about changing the Dexcom 3 here. The procedure for the Dexcom 7 is pretty much the same.
