Abstract

In one embodiment, the handheld injection device includes a first housing having a first axis and a second housing having a second axis. In one embodiment, the second housing is configured to support a needle. In one embodiment, the first axis and a second axis form an adjustable angle between about 180 degrees and about 90 degrees.

Claims

1. A handheld injection device comprising:

a first housing having a first axis;

a processor;

an input device operatively coupled to the processor;

a first chamber configured to contain a first injectable fluid;

a second chamber configured to contain a second injectable fluid;

the first and second chambers being contained in a distal region of the first housing and disposed in a side-by-side relationship with respect to each other;

a drive unit operatively coupled to the processor;

a second housing configured to support a needle having a second axis, the second housing being rotatable with respect to the first housing and adjustably positioned such that the first axis and the second axis form an adjustable angle; and

a memory device storing instructions which when executed by the processor, causes the processor, in conjunction with the input device and the drive unit, to;

(a) select a dilution ratio of the first injectable fluid to the second injectable fluid;

(b) based on the selected dilution ratio, produce an injectable mixed fluid by diluting the first injectable liquid with the second injectable liquid; and

(c) extrude the injectable mixed fluid.

2. The handheld injection device of claim 1, wherein the angle is adjustable between 180 degrees and 90 degrees.

3. The handheld injection device of claim 2, wherein the angle is adjustable based on the second housing being configured to be able to rotate between a plurality of fixed predetermined positions.

4. The handheld injection device of claim 2, wherein the angle is adjustable based on the second housing being configured to be able to continuously rotate between a range of positions.

5. The handheld injection device of claim 4, which includes an O-ring, wherein, after a specific angular orientation is set, the O-ring is configured to set and provide a holding force.

6. A handheld dermal filler injection device comprising:

a first housing having a first axis;

a processor;

an input device operatively coupled to the processor;

a first chamber configured to contain a dermal filler;

a second chamber configured to contain a biocompatible fluid to be mixed with the dermal filler;

the first and second chambers being contained in a distal region of the first housing and disposed in a side-by-side relationship with respect to each other;

a drive unit operatively coupled to the processor;

a second housing configured to support a needle having a second axis, the second housing being rotatable with respect to the first housing and adjustably positioned such that the first axis and the second axis form an adjustable angle; and

a memory device storing instructions which when executed by the processor, causes the processor, in conjunction with the input device and the drive unit, to;

(a) select a dilution ratio of the dermal filler to the biocompatible fluid;

(b) based on the selected dilution ratio, produce an injectable mixed fluid by diluting the dermal filler with the biocompatible fluid; and

(c) extrude the injectable mixed fluid.
