Device for maintaining sterile integrity of connected fluid pathways
View Patent ↗A device is provided for ensuring the sterile integrity of two separate fluid pathways during interconnection of the two pathways with a two-part connector assembly. The two-part connector assembly is of the type which comprises a male portion and a female portion, each portion initially having a port covered and protected by a peel-away strip. The device comprises a base assembly, a connector clamp assembly mounted to the base assembly and configured for securing the two-part connector assembly in position for interconnection of the male and female portions, and a strip withdrawal assembly mounted to the base assembly and configured for simultaneous withdrawal of the peel-away strips from the ports of the male and female portions.
1. A device for ensuring the sterile integrity of two separate fluid pathways during interconnection of the two pathways with a two-part connector assembly comprising male and female portions, each portion initially having a port covered and protected by a peel-away strip, the device comprising:
(a) a base assembly;
(b) a connector clamp assembly mounted to the base assembly and configured for securing the two-part connector assembly in position during interconnection of the male and female portions; and
(c) a strip withdrawal assembly mounted to the base assembly and configured for simultaneous withdrawal of the peel-away strips from the ports of the male and female portions.
2. The device of claim 1 , wherein the base assembly comprises a base having at least one upstanding wall extending therefrom, the upstanding wall having a front surface and a rear surface.
3. The device of claim 2 , further comprising a cradle affixed to the at least one upstanding wall and dimensioned for holding the two-part connector assembly.
4. The device of claim 3 , wherein the cradle further comprises a slot for the peel-away strips of the male and female portions of the two-part connector assembly to extend therethrough.
5. The device of claim 3 , wherein the connector clamp assembly comprises:
(a) a mounting arm pivotally connected to the base; and
(b) a toggle clamp connected to the mounting arm and comprising a positive locking mechanism,
wherein the positive locking mechanism secures the two-part connector assembly in position when the mounting arm and connected toggle clamp are pivoted toward the cradle.
6. The device of claim 2 , wherein the strip removal assembly comprises:
(a) a first plate slideable adjacent the front surface of the at least one upstanding wall along vertical slots formed in the at least one upstanding wall, the first plate having an uppermost vertical position;
(a) a first clamp portion affixed to the first plate and having a first clamping surface;
(c) a second clamp portion pivotally connected to the first clamp portion and having a second clamping surface; and
(d) a toggle clamp connected to the second clamp portion and comprising a positive locking mechanism, the toggle clamp having an open position and a closed position;
wherein with the first plate in the uppermost vertical position, the second clamp portion pivoted toward the first clamp portion, and the toggle clamp secured in a closed position by the positive locking mechanism, the strip removal assembly will positively grip the peel-away strips covering the ports of the male and female portions of the two-part connector assembly.
7. The device of claim 6 , wherein at least one of the first clamping surface of the first clamp portion and the second clamping surface of the second clamp portion comprises serrated teeth.
8. The device of claim 6 , further comprising:
(a) a second plate slideable adjacent the rear surface of the at least one upstanding wall along the vertical slots, the first plate having side edges and an uppermost vertical position in registration with the uppermost vertical position of the first plate; and
(b) a lever comprising a first end pivotally connected to the at least one upstanding wall, a second free end, the lever slideably connected between the first end and second free end to the second plate, and having an uppermost position;
wherein when the peel-away strips of the two-part connector assembly are positively gripped by the first and second clamp portions, and the lever is pivoted downwardly from the uppermost position, the peel-away strips are simultaneously withdrawn to uncover the ports of the male and female portions of the two-part connector assembly.
9. The device of claim 8 , wherein the strip removal assembly further comprises:
(a) a gripping surface on one of the side edges of the second plate, the gripping surface having an upper end and a lower end;
(b) a ratchet mechanism for engaging the gripping surface to limit upward movement of the lever, and for disengaging the gripping surface when the lever is moved downwardly to permit downward movement of the lever.
10. The device of claim 9 , wherein the ratchet mechanism comprises a pawl and a spring, and wherein the spring biases the pawl against the gripping surface.
11. The device of claim 2 , further comprising an engagement guide, having:
(a) an arm pivotally mounted to the at least one upstanding wall; and
(b) a notch formed in the arm and extending inwardly from an outer edge of the arm, the notch dimensioned to fit around the male portion of the two-part connector assembly, ensuring proper engagement of the male and female portions of the two-part connector assembly following withdrawal of the peel-away strips.
