The commonly used cystoscope, of which the Brown-Buerger is a type, has an irrigation inlet with the end beaded to receive the rubber connection tube from the irrigation can. This is applied and removed after the introduction of the cystoscope, and often several times during cystoscopy. If the tube is sufficiently tight to prevent leakage, it is difficult to apply without causing the patient pain from the manipulation, and, if it is loose, it slips off of itself or leaks.
The connection here described is the outgrowth of an effort to eliminate these disadvantages. It consists essentially of a male portion, beaded at one end to receive the irrigation tube, and, at the other end, a beveled tip which fits exactly into the female tip on the cystoscope. Attached to the male tip is a floating threaded ring which screws over a similar thread on the female tip, thus, by
