Design of saline drip package?

    Design of saline drip package??

    Hi all.
    I am studying the principle of the saline drip package in order to modify it to suit my slow-flow-rate delivery system.
    But I can hardly find any explanation of the principles involved.
    Do anyone have such links? or could you explain the principles of such a drip package?
    What's so special with such a design? Especially the thing encircled.
    It is said that the volume of each droplet remains the same all the time. But, so what?

    I always thought that, whatever that part is called, is used to set a constant flow rate. Since most medicines I have seen are based on volume, it makes sense to me. I would imagine it is simply an orifice that sets the flow. I'll join the hunt and see if I can find anything.

    Well here's what I could find on it. Apparently the typical setup is a gravity feed system.

    Hope this helps...

    Thanks. Such a device can produce a constant flow rate as the amount of saline consumes?

    Thanks. Let me have a look first.

    well the drip package has a controller by which you can adjust the frequency and flow rate of the medicine that has to be administered.
