Hydration pack for special case
 

This is a question so I can try and help my wife. She is starting to ride more post bariatric sleeve surgery. Because of this, she has a lot of issues with using straws. Does anyone make a hydration pack with a bulb type hand pump or equivalent so she doesn't have to suck on a bite valve?

If not, does anyone know if any of the hydration packs on the market use standard size tubing so I could add one myself? I know that there are food safe hand pumps in that style and size that could potentially work.

Sorry I do not know. But here are some bigger cages to carry large capacity bottles.

Widefoot.

I wonder if a pond store or pet store that sells fish might have some type of small pump with a switch (or which a switch could be added) to transfer water from the hydration pack up thru the hose? Would have to be small enough to fit into a hydration pack, and battery powered. Found this--works on 3-5 volts DC--you might be able to rig it to work. https://www.dx.com/p/zhaoyao-submers...l#.XqSUPvaSnIU Seems like a store that sells fish might have something similar.

The only down side to those would be good safety and any lubricants in the pump.

There are so many hose sizes and fittings available---surgical or food-grade---that you should have no trouble tracking down and rigging up something for your partner.
