Abstract

A self-centering vial clamp is provided. The self-centering vial clamp includes a clamp body including a vial aperture and two or more jaw slots spaced around the vial aperture, two or more clamp jaws spaced around the vial aperture, with a clamp jaw including a vial contact face and one or more jaw projections configured to engage a jaw slot of the clamp body, and two or more lever arms coupled to the two or more clamp jaws. A lever arm of the self-centering vial claim is configured to be manually pivoted, wherein the lever arm translates the pivoting motion into a sliding motion of the corresponding clamp jaw. Interacting lever gears formed on the lever arms constrain the two or more clamp jaws to move substantially in unison during the manual pivoting, aligning the vial.

First claim

The invention claimed is:

1. A method for aligning a vial to an instrument, the method comprising the steps of:
(i) obtaining a vial clamp having a clamp body, wherein the clamp body comprises:
a first clamp jaw and a first jaw guide slot, wherein the first clamp jaw is constrained by the first jaw guide slot;
a second clamp jaw and a second jaw guide slot, wherein the second clamp jaw is constrained by the second jaw guide slot;
an alignment projection extending from the clamp body configured to engage the instrument; and
a lever disposed on the clamp body and the first clamp jaw via the first jaw guide slot, wherein the lever includes lever gears that constrain the first and second clamp jaw;

(ii) obtaining the vial, wherein the vial is configured to contain material;
(iii) manually retracting the first and second clamp jaws by applying a force onto the lever;
(iv) manually placing the vial between the clamp jaws; and
(v) moving the first and second clamp jaws towards one another to secure the vial, the first and second clamp jaws being constrained by the lever gears to move substantially in unison toward the vial until the vial contacts the first and second clamp jaws, wherein, when the vial contacts the first and second clamp jaws, the vial is aligned to the instrument such that the instrument can access the material.

2. The method of claim 1 , wherein the step of moving includes removing the force applied onto the lever.

3. The method of claim 1 , wherein the step of moving includes applying a predetermined clamping force.

4. The method of claim 1 , wherein the first and second clamp jaws are moved substantially in unison toward the vial by sliding substantially in unison toward the vial.

5. The method of claim 1 , wherein the material contained in the vial is liquid, and the vial is open-ended.

6. A method for aligning a vial to an instrument, the method comprising the steps of:
(i) obtaining a vial clamp having a clamp body, wherein the clamp body comprises:
a first clamp jaw and a first jaw guide slot, wherein the first clamp jaw is constrained by the first jaw guide slot;
a second clamp jaw and a second jaw guide slot, wherein the second clamp jaw is constrained by the second jaw guide slot;
an alignment projection extending from the clamp body configured to assist in retaining the vial clamp to the instrument; and
lever gears that constrain the first and second clamp jaw;

(ii) obtaining the vial, wherein the vial is configured to contain material;
(iii) retracting the first and second clamp jaws, wherein the retracting includes applying a force onto at least one lever, the at least one lever being operatively coupled to the first clamp jaw;
(iv) placing the vial between the first and second clamp jaws; and
(v) moving the first and second clamp jaws toward the vial until the vial contacts the first and second clamp jaws, wherein the at least two clamp jaws are constrained by the lever gears to move substantially in unison, wherein, when the vial contacts the first and second clamp jaws, the vial is aligned to the instrument such that the instrument can access the material contained in the vial.

7. The method of claim 6 , wherein the step of retracting is performed manually.

8. The method of claim 6 , wherein the step of moving includes removing the force applied onto the lever.
