My question is how would you inflate two balloons simultaneously(for breast inflation? I have a tire pump but how do you connect two balloons to the same connection. Is there a type of hose that diverges or something that would attach to pump. Is there something I could build? Suggestions.
Two balloons, one pump?
I could only imagine that a plastic bag cut up in a tube and taped together would be the most inexpensive choice.
I'm not entirely sure what you're describing. Why make a tube when tubes (better ones at that) already exist?
Assuming you used two of the same balloons, you wouldn't need to worry about that because the pressure would equalize between the two...in theory. In practice you could add a check valve on either side of the Y junction and, assuming you have 2 of the same check valve, that should allow even flow, plus you won't have to worry about everything deflating once you remove the pump
I like the way you think. This calls for some experimentation.
Using a T-connector & 2 one-way valves (check the aquatic pet section in most department stores) About $8 worth of supplies.
You may still get uneven inflation but, with using a bicycle pump is it about as good as it will get.
Using air regulators for each line into the balloons is the ideal way to go, but would be difficult to do with a bike pump and much more costly.
Well, I use a bike pump too, but I have a length of aquarium tubing afixed to the end of the hose. I know that there are both "T" and "Y" connectors for such tubing that can split the air stream, though I have personally never tried it. One problem I foresee for your purposes would be keeping the air flow even on both sides of the divide. The only devices I can think of for such a use are electronic and complicated, not to mention expensive. I hope some of this has been helpful.
