Male bayonet connector

摘要

A male bayonet connector connects a section of tubing to a female latch connector. The male bayonet connector includes a shaft defining a lumen, a distal end portion, and a proximal end portion. The distal end portion of the shaft has a sealing surface configured to engage a seal member within the female latch connector to create a fluid-tight seal. The shaft defines an annular recess proximal to and adjacent the distal end portion. The annular recess has a proximal chamfered side wall and a distal sidewall perpendicular to the axis of the lumen, which are separated by a band of smaller diameter than the sealing surface. A grip is formed on the male bayonet connector between the proximal end portion and the annular recess. A ratio of a length of the first sealing surface to a distance between the grip and the distal sidewall is such that a side-load force, as imparted on the male bayonet connector, will not break a fluid-tight seal between the sealing surface and the seal member.

主权项

1. A male bayonet connector for connecting sections of tubing, the male bayonet connector comprising:
a first shaft including a first distal end portion, a first proximal end portion, and a first annular channel proximal to and adjacent the first distal end portion, a first lumen being defined between the first distal end portion and the first proximal end portion; and a grip attached to at least a portion of the first shaft, wherein: the first proximal end portion of the first shaft is configured to engage a first section of tubing; the first distal end portion of the first shaft has a first sealing surface configured to engage a first inner surface of a female receiving structure to create a fluid-tight seal; the first sealing surface has a constant diameter along a portion of its axial length and extends distally from the first annular channel; and the first annular channel is defined by a first distal sidewall that is perpendicular with respect to an axis of the first lumen, a first proximal sidewall having a first beveled edge, and a first bottom region connecting the first distal sidewall and the first beveled edge, with the first bottom region being concentric and recessed radially inward with respect to the first sealing surface.
