## Abstract

An injector including at least one fluid reservoir having a needle, a surface attached to skin and coupled to the fluid reservoir by at least a first joint and a second joint at least a portion of one of the joints being slidable or having interlocking arms. At least a portion of a path of translation of a slidable portion of the first joint and a portion of a path of translation of the second joint are angled in respect to each another.

## Claims

### Claim 1

An injector, comprising
at least one fluid reservoir connected to a needle;
a surface configured for attachment to skin and coupled to said fluid reservoir by at least a first joint and a second joint, said first and second joints each being configured to permit sliding of the fluid reservoir with respect to said surface, defining a first degree of freedom for each of said first and second joints,
wherein at least one of said first and second joints is also configured to permit a second degree of freedom with respect to said surface, said second degree of freedom being a rotational degree of freedom permitting rotation of the fluid reservoir, and
wherein when said fluid reservoir is rotated with respect to said surface, said sliding of said fluid reservoir with respect to said surface permitted by the first and second joints concurrently with said rotation of the fluid reservoir with respect to said surface permitted by the at least one of said first and second joints, converts a curvilinear travel path of the needle into at least a portion of said needle crossing the surface within less than 5 degrees deviated from a straight line.

### Claim 2 (depends on 1)

The injector according to claim 1, wherein at least a portion of a path of translation of said slidable portion of said first joint and a portion of a path of translation of said second joint are angled with respect to each another.

### Claim 3 (depends on 2)

The injector according to claim 2, wherein at least a portion of said path of translation of said slidable portion of said second joint restricts said at least a portion of said path of translation of said slidable portion of said first joint.

### Claim 4 (depends on 2)

The injector according to claim 2, wherein at least a portion of said path of translation of said second joint is curved.

### Claim 5 (depends on 4)

The injector according to claim 4, wherein at least a portion of said needle is tangential to a curve defined by said rotational degree of freedom.

### Claim 6 (depends on 2)

The injector according to claim 2, wherein when said fluid reservoir is rotated with respect to said surface, at least a portion of the travel path of at least a portion of said needle defined by at least said path of translation of said first joint and said path of translation of said second joint is configured to cross a surface of said skin along the straight line.

### Claim 7 (depends on 2)

The injector according to claim 2, wherein at least a portion of at least one of said paths of translation is configured to be parallel to said skin upon attachment of the surface thereto.

### Claim 8 (depends on 1)

The injector according to claim 1, wherein both degrees of freedom are on a same plane.

### Claim 9 (depends on 1)

The injector according to claim 1, wherein when said fluid reservoir is rotated with respect to said surface, at least a portion of the travel path of at least a portion of said needle defined by at least said respective first and second degrees of freedom is configured to cross the surface of said skin along the straight line.

### Claim 10 (depends on 9)

The injector according to claim 9, wherein said portion of said needle is the proximal edge of a bevel of said needle.

### Claim 11 (depends on 9)

The injector according to claim 9, wherein a tilt angle of said needle is generally parallel to said straight line.

### Claim 12 (depends on 9)

The injector according to claim 9, wherein said portion of said needle is a tip of said needle.

### Claim 13 (depends on 9)

The injector according to claim 9, wherein at least said two degrees of freedom define a path of travel at which at least a portion of said needle is configured to cross the surface of said skin angled at less than 3 degrees with respect to said straight line.

### Claim 14 (depends on 9)

The injector according to claim 9, wherein said portion of said needle is a tip that includes a beveled opening facing forward, away from a body of said fluid reservoir.

### Claim 15 (depends on 1)

The injector according to claim 1, wherein said needle is configured to form an entry hole in skin with a diameter (Φ) being twice the diameter (Φ′) of said needle.

### Claim 16 (depends on 1)

The injector according to claim 1, wherein at least one of said joints includes at least one pin-in-slot hinge.

### Claim 17 (depends on 16)

The injector according to claim 16, wherein at least one slot is configured to be oriented parallel to the surface of the skin upon attachment of the surface thereto.

### Claim 18 (depends on 1)

### Claim 19 (depends on 1)

The injector according to claim 1, wherein said fluid reservoir further comprises at least one angled head and plunger coupled to a tip of said head and wherein at least one of said joints comprises at least one slotted cylinder coupled to said surface and sized and fitted to slidingly accommodate said angled head and said plunger.

### Claim 20 (depends on 1)

The injector according to claim 1, wherein at least a portion of said needle is resilient.

### Claim 21 (depends on 1)

The injector according to claim 1, wherein at least a portion of said needle is curved.

### Claim 23 (depends on 1)

The injector according to claim 1, wherein at least one joint comprises an elastic member.

### Claim 24

An injector, comprising
at least one fluid reservoir connected to a needle;
a surface configured for attachment to skin and coupled to said fluid reservoir by at least a first joint and a second joint, said first and second joints each being configured to permit sliding of the fluid reservoir with respect to said surface, defining a first degree of freedom for each of said first and second joints, and wherein at least one of said first and second joints is also configured to permit at least a second, rotational degree of freedom permitting rotation of the fluid reservoir with respect to said surface and at least one of said joints comprises at least two interlocking arms,
wherein when said fluid reservoir is rotated with respect to said surface, said sliding of said fluid reservoir with respect to said surface permitted by the first and second joints concurrently with said rotation of the fluid reservoir with respect to said surface permitted by the at least one of said first and second joints, converts a curvilinear travel path of the needle into at least a portion of said needle crossing the surface within less than 5 degrees deviated from a straight line.

### Claim 25 (depends on 24)

The injector according to claim 24, wherein at least one of said interlocking arms is pivotably coupled to said surface.
