Abstract

A retainer comprises a first member and a second member. The first member can define at least a portion of a channel. The channel can have a longitudinal axis and be configured to receive at least a portion of a medical article. The second member can be moveable with respect to the first member, between locked and unlocked positions. The second member can contact the portion of the medical article received by the channel at least when in the locked position so as to inhibit longitudinal movement of the medical article relative to the retainer.

Claims

1. A retainer for securing a medical article to a patient, the retainer comprising:

a first member defining at least a portion of a channel and including a receptacle, the channel having a longitudinal axis and being configured to receive at least a portion of a medical article;

a second member, at least a portion of the second member being movably retained within at least a portion of the receptacle so as to move between a first position and a second position, the second member contacting at least a part of the received portion of the medical article at least when in the second position so as to inhibit longitudinal movement of the medical article through the channel, and

an actuator, wherein the actuator moves the second member from the first position to the second position.

2. The retainer of claim 1, wherein the second member extends into the channel at least when in the second position.

3. The retainer of claim 1, wherein the receptacle extends through the first member.

4. The retainer of claim 1, wherein the second member passes through the receptacle when the second member moves from the first position to the second position.

5. The retainer of claim 1, wherein the first member surrounds the receptacle.

6. The retainer of claim 1, wherein the first member comprises a first arm, a second arm, and a connecting portion.

7. The retainer of claim 6, wherein the receptacle is disposed in the first arm.

8. The retainer of claim 6, wherein the receptacle is disposed in the connecting portion.

9. The retainer of claim 1, wherein the second member moves in a first direction between the first position and the second position and the actuator moves in a second direction, the second direction being different than the first direction.

10. The retainer of claim 9, wherein the first direction is a radial direction with respect to the longitudinal axis through the channel.

11. The retainer of claim 1, wherein the second member slidingly engages with the first member.

24. The securement device of claim 2 further comprising a timer.

12. A securement device for securing at least a portion of a medical article, the device comprising:

a first arm comprising;

a guideway extending through the first arm;

an engaging piece movably disposed within at least a portion of the guideway so as to at least move through the guideway and towards the medical article;

an actuator movably disposed within at least a portion of the guideway and being coupled to the engaging piece so that movement of the actuator moves the engaging piece;

a second arm having a surface facing the first arm, the surface being configured to locate the medical article to be contacted by the engaging piece;

a connecting portion operatively connecting the first and second arms;

a ratcheting mechanism to hinder movement of the actuator relative to the engaging piece.

13. The securement device of claim 12, wherein the engaging piece comprises at least one projecting end configured to engage the medical article.

14. The securement device of claim 12, wherein the engaging piece is mounted within the guideway by one or more pin and slot joints.

15. The securement device of claim 12, wherein the engaging piece rotates and translates within the guideway.

16. The securement device of claim 12, wherein the engaging piece is biased in a direction away from the medical article.

17. The securement device of claim 16 further comprising a leaf spring, the leaf spring biasing the engaging piece.

18. The securement device of claim 12, wherein the second arm comprises a groove, at least a portion of the groove having an arcuate shape.

19. The securement device of claim 18, wherein the groove is provided at an angle relative to a primary plane of the securement device, and wherein the angle is approximately 7 degrees.

20. The securement device of claim 12, wherein the actuator is mounted within the guideway by one or more pin and slot joints.

21. The securement device of claim 12, wherein the guideway comprises a ramp, the actuator being slidable along the ramp.

22. The securement device of claim 12, wherein movement of the actuator and/or the engaging piece comprises sufficient friction to hinder movement of the engaging piece in a direction away from the medical article.

23. The securement device of claim 12 further comprising a flow sensor.

25. A securement device for securing at least a portion of a medical article, the device comprising:

a first arm comprising;

a guideway extending through the first arm;

an engaging piece movably disposed within at least a portion of the guideway so as to at least move through the guideway and towards the medical article;

an actuator movably disposed within at least a portion of the guideway and being coupled to the engaging piece so that movement of the actuator moves the engaging piece;

a second arm having a surface facing the first arm, the surface being configured to locate the medical article to be contacted by the engaging piece, wherein the second arm comprises a groove, at least a portion of the groove having an arcuate shape; and

a connecting portion operatively connecting the first and second arms.

26. The securement device of claim 25, wherein the groove is provided at an angle relative to a primary plane of the securement device, and wherein the angle is approximately 7 degrees.

27. A securement device for securing at least a portion of a medical article, the device comprising:

a first arm comprising;

a guideway extending through the first arm;

an engaging piece movably disposed within at least a portion of the guideway so as to at least move through the guideway and towards the medical article, wherein the engaging piece is biased in a direction away from the medical article;

an actuator movably disposed within at least a portion of the guideway and being coupled to the engaging piece so that movement of the actuator moves the engaging piece;

a second arm having a surface facing the first arm, the surface being configured to locate the medical article to be contacted by the engaging piece; and

a connecting portion operatively connecting the first and second arms.

28. The securement device of claim 27 further comprising a leaf spring, the leaf spring biasing the engaging piece.
