Abstract

A tamper-evident closure is disclosed that encloses a medical access device, such as a vascular access device, such that it will be visibly apparent if the medical access device contained in the tamper-evident closure becomes exposed. The tamper-evident closure cannot be reapplied over the medical access device in a way to look the same as it did prior to exposing the medical access device. The tamper-evident closure comprises a holding cavity, a securing mechanism, and an apparent release. The disclosed tamper-evident closure is well suited for securing the medical access device that has an access point for delivering fluid to a patient or removing fluid from the patient.

Claims (34)

1 . A tamper-evident closure, comprising:

a first part and a second part that co-operatively form a holding cavity;

a protruding channel extending along a portion of the first part;

a receiving channel defined in a portion of the second part, wherein the protruding channel is configured to align and engage with the receiving channel; and

a tear strip connected between one of (i) the protruding channel and the first part or (ii) the receiving channel and the second part,

wherein the tear strip is configured to disconnect from the one of the first part or the second part,

wherein the tamper-evident closure defines an access point and at least a portion of a medical access device is extendable through the access point into the holding cavity, and

wherein the tear strip comprises a channel locking fit that includes a plurality of teeth, and wherein the second part defines a plurality of cavities sized to receive the plurality of teeth.

2 . The tamper-evident closure of claim 1 , where the tear strip is between the protruding channel and the first part, and wherein removal of the tear strip is configured to:

disconnect the tear strip from the first part; and

disengage the protruding channel from the receiving channel.

3 . The tamper-evident closure of claim 1 , wherein the first part is pivotally, slidably, or rotatably connected with the second part.

4 . The tamper-evident closure of claim 1 , further comprising a tab connected with the tear strip, wherein actuation of the tab is configured to disengage the tear strip from the first part or the second part.

5 . The tamper-evident closure of claim 1 , further comprising front tabs extending on each side of the access point.

6 . The tamper-evident closure, of claim 1 , wherein the access point is a first access point and wherein the tamper-evident closure further defines a second access point that is not longitudinally aligned with the first access point.

7 . The tamper-evident closure of claim 6 , further comprising a door configured to cover the second access point.

8 . The tamper-evident closure of claim 7 , wherein the door is slidably connected to the second part to cover or expose the second access point.

9 . The tamper-evident closure of claim 1 , wherein the medical access device comprises a fluid delivery tube, and wherein the fluid delivery tube is configured to pass through the access point.

10 . The tamper-evident closure of claim 1 , wherein the plurality of teeth is receivable in the plurality of cavities to define a zig-zag line along a portion of the tamper-evident closure.

11 . A method, comprising;

inserting, into the tamper-evident closure of claim 1 , the medical access device; and

engaging the protruding channel of the first part with the receiving channel of the second part.

12 . A tamper-evident closure, comprising:

a first part and a second part rotatably coupled on a first side of the tamper-evident closure, wherein the first part and the second part co-operatively define a holding cavity and an access point through the first part and the second part into the holding cavity, and wherein at least a portion of a medical access device is extendable through the access point and into the holding cavity;

a protrusion extending along a portion of the first part on a second side of the tamper-evident closure;

a receiving channel defined along a portion of the second part on the second side, wherein the protrusion is receivable within the receiving channel;

a tear strip connected between (i) the protrusion and the first part or (ii) the receiving channel and the second part, wherein the tear strip is disconnectable from the first part or the second part, and

wherein the tear strip comprises a channel locking fit that includes a plurality of teeth, and wherein the second part defines a plurality of cavities sized to receive the plurality of teeth.

13 . The tamper-evident closure of claim 12 , wherein the first part is rotatable relative to the second part between an open position and a closed position, wherein the protrusion is received in the receiving channel to maintain the first part in the closed position, and wherein the tear strip is decouplable from the first part or the second part to allow the first part to transition to the open position.

14 . The tamper-evident closure, of claim 12 , wherein the access point is a first access point and the tamper-evident closure further defines a second access point that is longitudinally mis-aligned with the first access point.

15 . The tamper-evident closure of claim 14 , further comprising a door configured to cover the second access point.

16 . The tamper-evident closure of claim 15 , wherein the door is slidably connected to the second part to cover or expose the second access point.

17 . The tamper-evident closure of claim 12 , further comprising a front tab extending on each side of the access point.

18 . The tamper-evident closure of claim 12 , wherein the plurality of teeth is receivable in the plurality of cavities to define a zig-zag line along a portion of the tamper-evident closure.
