1. A releasable connection assembly for connecting tubing sections, the releasable connection assembly comprising:
- a male bayonet connector comprising a shaft comprising a distal end and a proximal end, the shaft defining a lumen extending between the distal end and the proximal end, wherein;
the distal end of the shaft comprises a sealing surface with a constant outer diameter at least partially along the axial length of the distal end of the shaft, and an annular channel proximal of the sealing surface, wherein the sealing surface with the constant outer diameter proximally terminates in a sidewall that is perpendicular to the longitudinal axis of the lumen defined by the shaft, and wherein the annular channel has an outer diameter that is smaller than the constant outer diameter of the sealing surface and is distally bound by the sidewall and is proximally bound by a chamfered or beveled sidewall that is angled with respect to the longitudinal axis of the lumen defined by the shaft, andthe proximal end of the shaft is configured to engage a first tubing section; and
a female latch connector comprising;
a proximal end defining a receiving aperture configured to receive at least part of the distal end of the shaft,a sealing member that is configured to contact the sealing surface of the distal end of the shaft, anda distal end comprising a tube coupling configured to engage a second tubing section.

19. A method of using a releasable connection assembly for connecting tubing sections, the method comprising:
-
receiving a male bayonet connector and a female latch connector in unassembled form, wherein; the male bayonet connector comprises a shaft comprising a distal end and a proximal end, the shaft defining a lumen extending between the distal end and the proximal end, the distal end of the shaft comprises a sealing surface with a constant outer diameter at least partially along the axial length of the distal end of the shaft, and an annular channel proximal of the sealing surface, wherein the sealing surface with the constant outer diameter proximally terminates in a sidewall that is perpendicular to the longitudinal axis of the lumen defined by the shaft, and wherein the annular channel has an outer diameter that is smaller than the constant outer diameter of the sealing surface and is distally bound by the sidewall and is proximally bound by a chamfered or beveled edge that is angled with respect to the longitudinal axis of the lumen defined by the shaft, and the proximal end of the shaft is configured to engage a first tubing section, and a female latch connector comprises a proximal end defining a receiving aperture configured to receive at least part of the distal end of the shaft, a sealing member that is configured to contact the sealing surface of the distal end of the shaft, a latch surface configured to prevent removal of the male bayonet connector from the female latch connector, and a distal end comprising a tube coupling configured to engage a second tubing section; inserting the at least part of the distal end of the shaft into the receiving aperture so that the sealing member contacts the sealing surface of the distal end of the shaft and the sidewall interfaces with the latch surface to assemble the male bayonet connector and the female latch connector; causing movement of the receiving aperture relative to the distal end of the shaft so that the latch surface clears the sidewall to allow removal of the at least part of the distal end of the shaft from the receiving aperture; and withdrawing the at least part of the distal end of the shaft from the receiving aperture to disassemble the male bayonet connector and the female latch connector. - View Dependent Claims (20, 21)
