## Abstract

A medicament dispensing device including a substantially rigid carpule body which has a dispensing end and an actuation end opposite the dispensing end. The carpule body is substantially tubular and thus defines a carpule bore. The device further includes a plunger operatively disposed within the carpule bore having a plunger actuator near the actuation end of the carpule body and a plunger tip opposite the plunger actuator. The plunger tip and an orifice at the dispensing end of the carpule bore define a medicament volume which may be loaded with a medicament selected to achieve specific therapeutic goals. The carpule body may also include a wound depth scale. The depth scale is typically associated with the dispensing end of the carpule body. Similarly, the medicament dispensing device may include a dosage scale. Also disclosed are methods of dispensing medicaments.

## Claims

### Claim 1

A medicament dispensing device comprising:
a substantially rigid carpule body having a dispensing end and an actuation end opposite the dispensing end, the carpule body further defining a carpule bore, wherein the carpule body is curved to provide an angular displacement between a central axis of the carpule body at the actuation end and a central axis of the carpule body at the dispensing end;
a plunger operatively disposed within the carpule bore having a plunger actuator near the actuation end;
a plunger tip opposite the plunger actuator;
a medicament volume defined by the carpule bore between the plunger tip and an orifice at the dispensing end; and a wound depth scale operatively associated with the dispensing end of the carpule body.

### Claim 2 (depends on 1)

The medicament dispensing device of claim 1 wherein the actuation end further comprises an enlarged head adapted to be received in a medicament dispensing gun.

### Claim 3 (depends on 1)

The medicament dispensing device of claim 1 further comprising a plunger extension engageable with the plunger actuator to provide for manual actuation of the plunger actuator.

### Claim 4 (depends on 3)

The medicament dispensing device of claim 3 further comprising an attachment ring connecting the plunger extension in sliding engagement with the carpule body.

### Claim 5 (depends on 1)

The medicament dispensing device of claim 1 further comprising a dosage scale operatively associated with the actuation end of the carpule body.

### Claim 6 (depends on 5)

The medicament dispensing device of claim 5 wherein the dosage scale comprises indicia associated with a notch, the notch further being operatively associated with the plunger actuator, which indicia indicate selected delivery of a partial dosage of a medicament.

### Claim 7 (depends on 6)

The medicament dispensing device of claim 6 further comprising a stop associated with the notch defining a limit to the travel of the plunger actuator which is associated with the delivery of a full dosage of the medicament.

### Claim 8 (depends on 1)

The medicament dispensing device of claim 1 wherein the plunger tip has substantially the same diameter as the orifice.

### Claim 9 (depends on 1)

The medicament dispensing device of claim 1 wherein the plunger tip defines a concave surface facing the orifice.

### Claim 10 (depends on 1)

The medicament dispensing device of claim 1 wherein the carpule body proximate the dispensing end is tapered.

### Claim 11 (depends on 1)

The medicament dispensing device of claim 1 wherein the axis of the carpule body at the dispensing end is angled from the axis of the carpule body at the actuation end.

### Claim 12 (depends on 1)

The medicament dispensing device of claim 1 wherein the curved carpule body provides for the axis of the carpule body at the dispensing end is angled from the axis of the carpule body at the actuation end at an angle of between 100 and 120 degrees.

### Claim 13 (depends on 1)

The medicament dispensing device of claim 1 further comprising a protective cover associated with the carpule body.

### Claim 14 (depends on 13)

The medicament dispensing device of claim 13 wherein the protective cover covers the entire carpule body.

### Claim 15 (depends on 14)

The medicament dispensing device of claim 14 wherein the protective cover comprises:
a tab, and
a scored seam facilitating the opening of the protective cover.

### Claim 16 (depends on 13)

The medicament dispensing device of claim 13 wherein the protective cover covers the dispensing end of the carpule body.
