ABSTRACT:
Low profile inlet valve embodiments for a piston pump therapeutic substance infusion device are disclosed that reduce dead volume, occupies little residential space, operates rapidly, and have many other improvements. The therapeutic substance infusion device has a housing, a therapeutic substance reservoir, a power source carried in the housing, electronics, a piston pump, and an inlet valve. The piston pump is configured for pumping therapeutic substance from the therapeutic substance reservoir through an infusion port at a programmed rate. The inlet valve is in fluid communication with a reservoir outlet to control the flow of therapeutic substance into the piston pump. The inlet valve has a substantially coplanar valve surface and valve spring. Many embodiments of the low profile inlet valve and its methods of operation are possible.
