I'm currently looking for a kind of tool that has this function: Pull to blow air, push to suck air.
Preferably tube like. I was looking into reverse syringes that has the opposite quality of a standard syringe in which nurses could draw out blood with one hand while pushing. However I'd assume it would not blow air when pushed.
Any suggestions or ideas of a tool that has the function mentioned above?
Anything would be appreciated.
Thanks.
