Abstract
Abstract A device for retaining at least two specimen collecting tubes in a preselected spaced relationship includes an elongate structure having first and second arm portions joined by a flexible hinge portion, each of the arm portions defining a first surface engageable with a first tube and a second surface engageable with a second tube. The device includes provision for joining the arm portions to each other at locations remote from the hinge portion to confine the tubes between the arm portions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
160 words
A device for retaining at least two specimen collecting tubes in a preselected spaced relationship, comprising an elongate structure having first and second arm positions joined by a flexible hinge portion, each of the arm portions defining a first arcuate surface engageable with a first specimen collecting tube and a second arcuate surface engageable with a second specimen collecting tube with the first and second arcuate portions of the respective arms being positioned symmetrically relative to said hinge portion, each of said arm portions further having a substantially flat surface portion extending between the first and second arcuate surfaces, said flat surface portion including means for connecting the arms to each other so that the flat surface portions between the arcuate surfaces are in a substantially parallel spaced apart relationship to confine the tubes between the arm portions and second means for connecting the arms to each other at substantially the extremity of the arms remote from the hinge portion.
Claim 2
Independent Claim
160 words
A device for retaining at least two specimen collecting tubes in a preselected spaced relationship, comprising an elongate structure having first and second arm positions joined by a flexible hinge portion, each of the arm portions defining a first arcuate surface engageable with a first specimen collecting tube and a second arcuate surface engageable with a second specimen collecting tube with the first and second arcuate portions of the respective arms being positioned symmetrically relative to said hinge portion, each of said arm portions further having a substantially flat surface portion extending between the first and second arcuate surfaces, said flat surface portion including means for connecting the arms to each other so that the flat surface portions between the arcuate surfaces are in a substantially parallel spaced apart relationship to confine the tubes between the arm portions and second means for connecting the arms to each other at substantially the extremity of the arms remote from the hinge portion.
Claim 3
Dependent Claim
17 words
The device recited in claim 1 wherein the arm portions are formed integrally with the hinge portion.
Claim 4
Dependent Claim
18 words
The device recited in claim 2 wherein the elongate structure is formed of injection molded organic polymeric material.
Claim 5
Dependent Claim
25 words
The device recited in claim 2 wherein the hinge portion is a strap of the elastomeric material which is substantially thinner than the arm portions.
Claim 6
Dependent Claim
59 words
The device recited in claim 1 wherein at least one of said means for connecting comprises at least one enlarged projection on one of the arm portions and a restricted opening in the other arm portion, the projection being receivable within the restricted opening and having an undercut portion engageable with the opening when the projection is received therein.
Claim 7
Dependent Claim
19 words
The device recited in claim 5 wherein the enlarged projection is tapered to facilitate reception within the restricted opening.
Claim 8
Dependent Claim
25 words
The device recited in claim 5 wherein the first and second arcuate surfaces have a plurality of ribs thereon for frictionally retaining the tubes therebetween.
Claim 9
Dependent Claim
23 words
The device recited in claim 1 wherein each arm portion is substantially rigid in the area adjacent to the flat surface portion thereof.
