Abstract
Abstract A meatal dilator designed specifically to dilate the urethra has a relatively long dilating shaft one of whose ends is tapered to a blunt tip. The other end of the shaft is connected to a grip designed to fit the hand. A protective diaphragm arranged perpendicularly to the shaft is interposed between the shaft and the grip to limit the depth of penetration of the dilator. Also, a generally cylindrical cap containing an antibiotic and/or lubricant is snugly engaged over the head of the shaft and removably held in place to protectively enclose the shaft.

Claim 1
Independent Claim
130 words
A urethral meatal dilator comprising an elongated, generally cylindrical shaft which tapers at one end to a relatively blunt tip, a finger-gripping handle attached to the other end of the shaft, a discoid shield formed on the shaft adjacent the handle for limiting the depth of penetration of the dilator, a raised collar on the shaft adjacent the shield, a generally cylindrical cap whose diameter and length are slightly larger than the corresponding dimensions of the shaft and collar so that the cap can be engaged over the shaft to protectively enclose it, a lubricant or antibiotic inside the cap and means for removably securing the cap on the shaft, said securing means including an internal bead extending around the open end of the cap for frictionally engaging the collar.
