ABSTRACT:
A safety device for use with Foley catheters and the like to prevent internal lacerations of the bladder neck and urethra which may occur as a result of accidental dislocation of such catheters. A coupler assembly is utilized to join the previously severed sections of the catheter. Several axially aligned slits are made in one severed section of the catheter to form a plurality of strips. One hollow tubular projection of the coupler is fitted into the opening of this section whereupon the strips of this section of the catheter are inserted into anchoring notches to lock the coupler thereto. The remaining portion of the catheter is force fitted into an oppositely directed hollow tubular projection. Thus the first catheter section which is placed within the bladder of a patient, is free to remain seated within the bladder with the remaining section of the catheter being adapted to be released from the coupler without pulling the anchored catheter section out of the bladder.
The locking notches of the coupler also provide a fluid (i.e., water and/or air) tight seal for the fluid (i.e., water and/or air) passageway extending between the inflatable portion of the catheter and the air pressure input end to maintain the inflatable portion in the inflated condition thereby assuring proper placement of the catheter within the bladder.
