Finger actuated medication infusion system

An apparatus for delivering a flow of medication over an extended period of time into a living body, said apparatus comprising:

• a medication reservoir for holding said medication in readiness for delivery into said living body;
• pump means for receiving medication from said reservoir and for mechanically delivering said medication into said living body over the extended period of time;
• connecting means for facilitating passage of said medication from said reservoir to said pump means and communicating therebetween;
• and
• dosing means disposed within and forming a part of said pump means, for providing a predetermined dosage of medication for delivery into the living body, said pump means being manually actuatable with a predetermined stroke to fill said dosing means by drawing medication from said reservoir, and said dosing means being operable to deliver medication into the living body upon release of said pump means.

An apparatus for delivering a flow of medication over an extended period of time into a living body, said apparatus comprising:

• a medication reservoir for holding said medication in readiness for delivery into said living body:
• pump means for receiving medication from said reservoir and for mechanically delivering said medication at a predetermined decaying dosage rate into said living body over the extended period of time;
• connecting means for facilitating passage of said medication from said reservoir to said pump means and communicating therebetween;
• dosing means disposed within said pump means for providing a predetermined dosage of medication for delivery into the living body, said pump means being manually actuatable with a predetermined stroke to fill said dosing means by drawing medication from said reservoir, and said dosing means being operable to deliver medication into the living body upon release of said pump means
• said reservoir having a valve assembly connecting with said connecting means, said valve assembly providing a seal for said reservoir and remaining closed except when said pump means is actuated;
• and
• said pump means including an incompressible fluid surrounding said dosing means, said predetermined dosage rate thereby being essentially independent of ambient pressure.

• said reservoir having a valve assembly connecting with said connecting means, said valve assembly providing a seal for said reservoir;
• and
• said pump means having a valve assembly connecting with said connecting means, said reservoir valve assembly and said pump means valve assembly remaining closed except when said pump means is actuated, said connecting means thereby maintaining a positive pressure therein.

• pump means for receiving medication from said reservoir and for mechanically delivering said medication at a predetermined decaying dosage rate into said living body over the extended period of time, said pump means being manually actuatable with a predetermined stroke to fill said pump means by drawing medication from said reservior, and being operable to deliver medication into the living body upon being released;
• connecting means for facilitating passage of said medication from said reservoir to said pump means and communicating therebetween;
• and
• filter means disposed upstream from said pump means for preventing the passage of bacteria and gas bubbles from said reservior into said pump means.
