Luer activated device with minimal fluid displacement
First Claim
Patent Images
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 closing the inlet of the valve housing, said valve element including a first and second normally closed resealable apertures, the first aperture having a higher opening pressure than the second aperture, the first and second apertures surrounding a space adapted to receive a male luer to allow fluid to be transferred between the male luer and the flow path, wherein there is substantially no fluid displacement when at least a portion of the male luer is inserted into or removed from the space, and wherein the second aperture is opened via pressure from a fluid introduced at the fluid outlet.

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 an aperture adapted to receive the male luer. The valve element is adapted such that a male luer inserted into the aperture will open fluid flow through the inlet without causing a substantial change in fluid displacement.

11. A medical fluid 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 including (i) a septum sealing the inlet, the septum defining a first aperture, (ii) a seal defining a second aperture, and (iii) a chamber wall separating the seal from the septum, the chamber wall constructed and arranged such that the male luer when fully received within the valve housing opens only the first aperture. - View Dependent Claims (12, 13, 14, 15, 16)

20. 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 closing the inlet of the valve housing, said valve element including a first and second normally closed resealable apertures, the first aperture having a higher opening pressure than the second aperture, the first and second apertures surrounding a space adapted to receive a male luer to allow fluid to be transferred between the male luer and the flow path, wherein there is substantially no fluid displacement when at least a portion of the male luer is inserted into or removed from the space, and wherein the second aperture closes automatically upon completion of fluid transfer through the medical valve.

21. 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; a valve element closing the inlet of the valve housing, said valve element including a first and second normally closed resealable apertures, the first aperture having a higher opening pressure than the second aperture, the first and second apertures surrounding a space adapted to receive a male luer to allow fluid to be transferred between the male luer and the flow path, wherein there is substantially no fluid displacement when at least a portion of the male luer is inserted into or removed from the space; and which includes a septum closing the inlet of the valve housing, the septum defining the first aperture, and a seal spaced apart from the septum, the seal defining the second aperture, and wherein the seal is spaced apart from the septum by a collapsible wall.
