I found this listing for a "Wall Aneroid Sphygmomanometer with ABS shaped dial, Best sphygmomanometer" on Alibaba (
http://www.alibaba.com/product-detail/W ... 59643.html).

Although there are many listing for nearly identical ones, this was the only listing that had a picture of it disassembled, and it looks like one of the parts is a Motion Tracker pump widget (it's not quite accurate, though).

I contacted the company and they said, if I ordered 10 widgets, it would be $45 per unit.
By the way, does anyone know what the pump widget is supposed to do (in the sphygmomanometer)?
