Enclosure with cam action snap release
View Patent ↗Apparatuses and methods for maintaining sterile connections during, for example, dialysis therapy. The present invention provides a container for a medical device and a lid therefore. The lid and the container are configured for an easy snap release using a cam-follower system. The invention also provides a method for using an assembly of the container, lid and a medical device within the container to maintain sterile connections.
1. A container for a medical device comprising:
a body defining a passage, the body having a bottom surface and an edge opposite the bottom surface, the bottom surface having an integrally formed securing mechanism releasably retaining the medical device securely in the body, the edge defining a first cam-follower member, the medical device is a cap for use in making a resealable fluid path wherein one end of the cap is operatively connectable to a peritoneal cavity of a patient and another end of the cap is operatively connectable to a fluid container; and
a lid defining a second cam-follower member, the lid and the body being configured to provide a snap release of the lid from the body in response to a cam-follower action between the first and second cam-follower members.
2. The container of claim 1 , wherein the body includes a collar defining the opening, the collar having a continuous cam edge geometry.
3. The container of claim 2 , wherein the lid includes a follower for engaging the cam edge geometry, so that turning the lid will push the lid away from the container.
4. The container of claim 1 , wherein the body includes a collar which engages and secures the lid by means of a snap mechanism.
5. The container of claim 1 , wherein the body includes an integrally formed handle attached to the bottom surface of the body.
6. The container of claim 1 , further comprising a medical device disposed within the container.
7. The container of claim 1 , wherein the medical device further comprises a seal disposed within an interior surface, the seal maintaining a disinfectant.
8. The container of claim 7 , wherein the disinfectant comprises povidone iodine.
9. The container of claim 1 , wherein the lid includes a downwardly extending projection for engaging and holding the medical device in place.
10. The container of claim 1 , wherein the integrally formed securing mechanism engages an interior surface of the medical device so that the device is held securely within the container.
11. The container of claim 1 , wherein the lid includes an integrally formed handle.
12. The container of claim 1 , wherein the lid includes a tip protector for engaging a slit septum of the medical device.
13. The enclosure of claim 1 , wherein the first cam-follower member forms a cam surface and the second cam-follower member forms a follower surface.
14. An enclosure for a medical device comprising:
a body defining a passage, the body including a bottom surface having an integrally formed securing mechanism releasably retaining the medical device securely in the body, the medical device is a cap for use in making a resealable fluid path wherein one end of the cap is operatively connectable to a peritoneal cavity of a patient and another end of the cap is operatively connectable to a fluid container;
a lid, the lid and the body being configured to provide a snap release of the lid from the body in response to a cantilever action between the body and the lid;
an edge including projections and undulations located on one of the body and the lid;
a follower defined on the other of the body and the lid; and
wherein the cantilever action is caused by a movement of the edge relative to the follower.
15. The enclosure of claim 14 , wherein the projections and undulations form a saw-tooth configuration.
16. The enclosure of claim 14 , wherein the body includes a handle arranged to extend substantially along the central axis.
17. The enclosure of claim 14 , wherein the edge having the projections and undulations is located on the body.
18. The enclosure of claim 17 , wherein the cap includes a slit septum.
19. The enclosure of claim 18 , wherein slit septum is configured to engage a downwardly extending projection formed within the lid.
20. The enclosure of claim 17 , wherein the cap includes an interior surface configured to include a seal.
21. The enclosure of claim 20 , wherein the seal supports a disinfectant.
22. A medical component enclosure, the enclosure comprising:
a body extending along a central axis, the body having an open end that includes an edge having a continuously changing geometry extending in a direction substantially parallel to the central axis; and
a lid sized to cooperate with the open end of the body to form a seal therebetween, wherein the edge is configured such that the lid translates with respect to the open end of the body in response to a twisting force to disengage the seal and allow access to a medical component releasably retained by the body, the medical component is a cap for use in making a resealable fluid path wherein one end of the cap is operatively connectable to a peritoneal cavity of a patient and another end of the cap is operatively connectable to a fluid container.
23. The enclosure of claim 22 further comprising a securing mechanism carried within the body, the securing mechanism aligned substantially along the central axis of the body.
24. The enclosure of claim 22 , wherein the lid includes a follower surface configured to engage the continuously changing geometry of the edge when the seal is disengaged.
25. The enclosure of claim 22 , wherein the continuously changing geometry includes a saw-tooth configuration.
