1. A light, thin, and flexible medication infusion apparatus that is bendable and attachable to the user'"'"'s skin comprising:

  • a flexible pad;

    installing any number of hard reservoir cells on said flexible pad where the pressure in said reservoir cells will not change if said reservoir cells are pressed;

    installing a soft and flexible membrane in each said reservoir cell to divide the space in all said reservoir cells into the medicine space and the air space;

    filling said medicine space with the medicine to be delivered into the user'"'"'s body;

    filling said air space with fluid;

    installing a pumping means on said flexible pad to pump fluid;

    installing a pumping controller means on said flexible pad to control said pumping means;

    installing battery means on said flexible pad;

    arranging, merging too small ones of, and dividing too large ones of said reservoir cells, said pumping means, said pumping controller means, and said battery means so that each hard embodiment on said flexible pad has appropriate size and any adjacent hard embodiments on said flexible pad have enough gap to let the user bend his or her body comfortably;

    installing flexible cable means to link said pumping controller means and said battery means so that said battery means provides electricity to said pumping controller;

    installing flexible cable means to link said pumping controller means and said pumping means so that said pumping controller means gets information from said pumping means and forwards and stops current to said pumping means at appropriate moments of time, respectively;

    installing flexible medicine linking means to link all said medicine space and the insertion means that inserts into the user'"'"'s body where the pressure in said medicine linking means will not change when said apparatus is bent;

    installing flexible air linking means to link all said air space and said pumping means where the pressure in said air linking means will not change when said apparatus is bent;

    installing valve means to control the air flow in all said air space and in said air linking means; and

    installing monitor and controller means separated from said medication infusion apparatus and installing communicating means between said monitor and controller means and said pumping controller means;

    so that said medication infusion apparatus is bendable and attachable to the user'"'"'s skin;

    the user can issue commands to said monitor and controller means about when and how much medicine to be delivered into the user'"'"'s body;

    said monitor and controller means issues instructions to said pumping controller means about how much fluid to be pumped into said air space at the moments according to the user'"'"'s commands;

    said pumping controller means controls said pumping means to pump the right amount of fluid into said air space at the right moment through said air linking means;

    the right amount of medicine is pressed out from said medicine space into the user'"'"'s body through said medicine linking means and said insertion means at the right moment; and

    said monitor and controller means collects information from said pumping controller means and said apparatus and displays the information to the user.
