cryotherapy tool

Freezpen is a cryotherapy tool shaped like an extremely large pen. It’s a versatile instrument that can be used in many different situations.

What’s good about it

We predominantly use Freezpen for freezing off little tumours that can appear pretty much anywhere on the body of dogs and cats. It also can stop the bleeding of very small blood vessels but that’s not its intended use. You just aim the tip at the tumour, hit the button and a spray of liquid nitrogen quickly freezes the tumour. 

I’ve used the other cryo-tools where you have to repeat the process a few times to get rid of the tumour. However, one application with the Freezpen is enough. There’s no need to go back and do it a second time. In that respect, it’s superior to other cryo-tools we’ve used in the past.

It’s important to keep plenty of liquid nitrogen cartridges on hand. They come in a pack of 12 and are relatively inexpensive to purchase.

It’s very common to find multiple small tumours on the belly of dogs and it’s simply not worth it to remove them surgically. The Freezpen fixes them up quite nicely.

What’s not so good

The only problem is with the canister of nitrogen that’s placed inside the pen. You only get about 90 seconds of use out of it.
