Buzzy for pain relief

[bookpixie]

Hi everyone ,
I was wondering if anyone had run across Buzzy for pain relief before?.
We have been looking at alternative ways to help children with pain relief from injections, minor procedures and diabetes ect and we have found this Buzzy UK which keeps popping up in our research we would like to get one for the hospitals children’s unit but we think we may run into trouble with having to freeze the wings as it would mean buying a small freezer just for buzzy because of our infection control policies ect although the idea of the disposable wings will help greatly we would still need the freezer.
I guess what I'm asking is if anyone has heard of someone who has a Buzzy or uses it them selves and if they have found it effective or if they have run into any issues like we have?.
We would really appreciate any input anyone has.
