Abstract

A connector for affecting aseptic juncture of two bodies for flow of fluid therebetween comprises a female element having a base, a conduit passing through the base, a cylindrical sheath extending from the base and concentrically spaced about a portion of the conduit, an annular exterior wall extending from the base a greater distance than the sheath and concentrically spaced thereabout and pellicular means for sealing the annular exterior wall at a position remote the base, with a male element telescopingly engageable with the female element and including a sole, a conduit passing through the sole and tubular means extending from the sole a greater distance than the conduit and concentrically spaced thereabout. Means are provided for retaining the male and female elements in telescoping engagement. Puncturable pellicular membranes at the extremities of the male and female elements maintain the element interiors in an aseptic condition until the membranes are ruptured when the male and female elements are joined.

Claims

1. An aseptic connector for affecting aseptic juncture of two bodies, for fluid flow therebetween, through said connector, comprising:

(a) a female element including;

(i) a base;

(ii) a first conduit passing through said base, a first end thereof communicating with said first body, a second end thereof extending distally from said base;

(iii) a cylindrical sheath extending from said base a greater distance than said second end of said first conduit, concentrically spaced about said distally extending second end of said first conduit;

(iv) an annular exterior wall extending from said base a greater distance than said sheath, concentrically spaced about said sheath, a distal end of said exterior wall defining a first orifice; and

(v) first pellicular means for sealing said first orifice at said annular exterior wall distal end;

(b) a male element, telescopingly engageable with said female element, including;

(i) a sole;

(ii) a second conduit passing though said sole, a first end thereof communicating with said second body, a second end thereof extending distally from said sole, said second conduit telescopingly insertable into said first conduit;

(iii) tubular means extending from said sole a greater distance than said second conduit, concentrically spaced about said second conduit, having an outer diameter less than inner diameter of said annular wall, said tubular means telescopingly insertable into said annular exterior wall; and

(c) means for retaining said male and female elements in telescoping engagement, with said tubular means at least partially resident within said annular exterior wall and said second conduit at least partially resident within said first conduit.

2. The connector of claim 1 further comprising second pellicular means for sealing said tubular means remote said sole.

3. The connector of claim 2 further comprising third pellicular means for sealing said second end of said first conduit.

4. The connector of claim 1 wherein a distal end of said tubular means, remote said sole, is a puncturing probe for said first pellicular means and is skew with respect to said sole.

5. The connector of claim 2 wherein a distal end of said sheath, remote said base, is a puncturing probe for said second pellicular means and is skew with respect to said base.

6. The connector of claim 1 wherein said retaining means further comprises:

(a) a circumferential groove within said annular exterior wall; and

(b) a protruding detent, configured for complemental engagement with said groove, about said tubular means exterior, when said male and female elements are telescopingly engaged.

7. The connector of claim 6 wherein said groove has a bottom portion more remote from said base than a vertex portion of said groove, to retain said detent within said notch upon insertion of said tubular means into said annular exterior wall.

8. The connector of claim 6 wherein said detent extends circumferentially around said tubular means exterior.

9. The connector of claim 6 wherein said detent includes a portion perpendicular to said tubular means exterior and proximate said sole and said notch includes a detent receiving portion perpendicular to said annular exterior wall.

10. The connector of claim 6 wherein said detent tapers along a surface from said tubular means exterior to a vertex.
