Abstract
An injection device with a puncture function includes, in a single casing, a cylindrical cartridge in which insulin is enclosed, a cartridge holder to which the cartridge is inserted, a needle inserted at a front end of the cartridge, a reciprocation unit for reciprocating the cartridge toward the needle, and an extrusion member for extruding the insulin from a rear end of the cartridge toward the needle, and the motion speed and the motion amount of the reciprocation unit are made variable.
Claims15
An injection device with puncture function, comprising:
- a cartridge having a chemical solution enclosed therein, a front end, and a needle inserted in the front end;
- a cartridge holder into which the cartridge is inserted;
- a reciprocation unit configured to reciprocate the cartridge and the cartridge holder;
- and
- an extrusion member configured to extrude the chemical solution from a rear end of the cartridge toward the needle, said extrusion member including:
- a motor,
- a rotation/linear motion conversion unit which is disposed between a rotation axis of the motor and a piston that pushes the rear end of the cartridge, and
- a rpm detection unit for detecting a rpm of the motor;
- wherein the reciprocation unit is configured to vary a motion speed and an amount of motion of the reciprocation unit while reciprocating the cartridge and while puncture by the needle or administration of the chemical solution through the needle is carried out.
