Abstract

A manually operated medicament infusion device is provided. The device is capable of delivering an accurately controlled volume of medicament with reliability. Additionally, the device includes a battery-operated indication device for tracking the number of doses of medication delivered. Optionally, the device includes a ratchet and pawl to prevent inadvertent dispensing of medicament.

Claims

1. A medicament infusion device comprising:

a.) a housing;

b.) a battery-operated indication device within the housing, wherein the indication device provides information about the medicament;

c.) a manually operated gearing mechanism;

d.) a piston comprising a piston end, wherein the is piston indexed in a first direction in response to action of the gearing mechanism;

e.) a medicament cartridge having a plunger therein that is engaged by the piston end;

f.) a removable retainer for retaining the medicament cartridge and piston therein; and

g.) a sensing mechanism for sensing a position of the piston on the leadscrew.

2. The infusion device of claim 1, wherein the gearing mechanism further comprises a manually operated drive wheel, a leadscrew base and a leadscrew shaft extending from the leadscrew base and wherein the is piston indexed along the leadscrew shaft in the first direction response to turning of the drive wheel.

3. The infusion device of claim 1, further comprising a rewind tool for returning the piston to an initial position on the leadscrew.

4. The infusion device of claim 1, further comprising a ratchet and pawl capable of preventing inadvertent turning of the drive wheel.

5. The infusion device of claim 1, further comprising an adhesive pad on a surface of the housing for adhering the infusion device to a body of a device user.
