Abstract
Abstract A retainer is used in combination with two tubular flow connectors to prevent the inadvertent disconnection of I.V. tubing sets. The retainer includes at least one open collar having a flexible opening so as to be radially and securely attachable adjacent to an increased diameter portion on a tubing connector. A pair of parallel straps connects the collar with an axially pivotable joint so as to facilitates easy manipulation and engagement of the retainer.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A retainer used in combination with first and second tubular fluid flow connectors, the first connector having a first increased diameter radial shoulder, the first connector axially connected in fluid flow communication with the second tubular fluid flow connector, the second connector having a second increased diameter radial shoulder, the retainer comprising: a first open collar having a first flexible opening so as to be radially attachable to the first tubular connector adjacent to the first radial shoulder; a second open collar having a second flexible opening so as to be radially attachable to the second tubular connector adjacent to the second radial shoulder; and a pair of parallel straps connecting the first collar to the second collar, the pair of straps connected at a first end by a first pair of axially pivotable joints to the first collar and connected at a second end by a second pair of axially pivotable joints to the second collar.
Claim 2
Dependent Claim
157 words
A retainer used in combination with first and second tubular fluid flow connectors, the first connector having a first increased diameter radial shoulder, the first connector axially connected in fluid flow communication with the second tubular fluid flow connector, the second connector having a second increased diameter radial shoulder, the retainer comprising: a first open collar having a first flexible opening so as to be radially attachable to the first tubular connector adjacent to the first radial shoulder; a second open collar having a second flexible opening so as to be radially attachable to the second tubular connector adjacent to the second radial shoulder; and a pair of parallel straps connecting the first collar to the second collar, the pair of straps connected at a first end by a first pair of axially pivotable joints to the first collar and connected at a second end by a second pair of axially pivotable joints to the second collar.
Claim 3
Dependent Claim
19 words
The retainer of claim 1 wherein the first and second pair of pivotable joints pivot in opposite axial directions.
Claim 4
Dependent Claim
32 words
The retainer of claim 1 wherein at least one of the first and second pair of pivotable joints is offset from the axial center of one of the first and second collars.
Claim 5
Dependent Claim
30 words
The retainer of claim 1 wherein the first and second open collars have openings that are dimensioned so as to attach to the respective tubular connectors with a snap fit.
