Abstract

A luer activated device includes an inlet adapted to receive a male luer, an outlet associable with a fluid flow system, and a flow path defined therebetween. The inlet receives a resealable valve element having a aperture adapted to receive the male luer. The valve element is compressible, such that a male luer inserted into the aperture will cause the valve element to primarily compress, rather than stretching and deforming. One end of the aperture may include a pressure activated flow passage, which is adapted to open upon fluid flow through a male luer received by the aperture. Methods of using such luer activated devices are also provided.

Claims

1. A medical valve for the bi-directional transfer of fluid, comprising:

a valve housing having an inlet adapted to receive a male luer, an outlet and a flow path defined therebetween; and

a valve element fixedly received within the inlet of the valve housing, said valve element including a resealable slit adapted to receive a male luer to allow fluid to be transferred between the male luer and the flow path, said valve element substantially comprised of a compressible material that substantially compresses to accommodate the male luer as at least a portion of the male luer is inserted into and through the operative of the valve element, wherein there is substantially no fluid displacement when the male luer is inserted or removed from the aperture.

2. The medical valve of claim 1 in which the compressible material is a polymeric foam.

3. The medical valve of claim 2 in which the polymeric foam is a silicone or urethane foam.

4. The medical valve of claim 2 in which the polymeric foam is a closed-celled foam.

5. The medical valve of claim 2 in which the polymeric foam is an open-celled foam.

6. The medical valve of claim 5, further comprising at least one vent in the valve housing, which vent is adapted to transfer air from the valve element to the ambient atmosphere when the valve element is compressed.

7. The medical valve of claim 1, wherein the valve element further comprises an antiseptic accent therein releasable upon compression.

8. The medical valve of claim 1, wherein the volume of the valve element in an uncompressed condition is substantially the same as the combined volumes of the valve element in a compressed condition and the portion of a male luer received within the inlet when the male luer is fully inserted into the inlet.

9. A medical valve for the bi-directional transfer of fluid, comprising:

a valve housing having an inlet adapted to receive a male luer, an outlet and a flow path defined therebetween; and

a valve element fixedly received within the inlet of the valve housing and substantially comprised of a compressible material, said valve element including

a resealable aperture adapted to receive at least a portion of a male luer and

at least one fluid flow passage at an end of the aperture, wherein said flow passage is adapted to open upon fluid flow through a male luer at least partially received by the slit.

10. The medical valve of claim 9 in which the material of the valve element is a polymeric foam.

11. The medical valve of claim 10 in which the polymeric foam is a silicone or urethane foam.

12. The medical valve of claim 10 in which the polymeric foam is a closed-celled foam.

13. The medical valve of claim 10 in which the polymeric foam is an open-celled foam.

14. The medical valve of claim 13, further comprising at least one vent in the valve housing, wherein the vent is adapted to transfer air from the valve element to the ambient atmosphere when the valve element is compressed.

15. The medical valve of claim 9, wherein said fluid flow passageway is adapted to automatically close upon cessation of fluid flow through a male luer at least partially received by the valve element aperture.

16. The medical valve of claim 9, wherein the valve element further comprises an antiseptic agent therein releasable upon compression.

17. A method of transferring fluid between a male luer and a fluid flow system, comprising:

providing a medical valve having a sealed inlet adapted to receive a male luer, an outlet in fluid communication with a fluid flow system, and a flow path defined therebetween;

inserting a male luer into the inlet and through a resealable aperture of a compressible valve element fixedly received within the valve, thereby compressing the valve element to allow fluid communication between the male luer and said flow path of the medical valve, wherein there is substantially no fluid displacement when the male luer is inserted into the aperture; and

commencing fluid flow through one of the fluid flow system and the male luer and into the flow path of the medical valve.

18. The method of claim 17, wherein said providing a medical valve includes providing a valve element substantially comprised of a polymeric foam.

19. The method of claim 17, wherein said providing a medical valve includes providing a valve element substantially comprised of a silicone or urethane foam.

20. The method of claim 17, wherein said providing a medical valve includes providing a valve element substantially comprised of a closed-celled foam.
