Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
185 words
A catheter guide for use in inserting a catheter through a urethra into a bladder comprising a molded one-piece device of resilient material having a tubular portion of a predetermined length which is insertable partially into the urethra, and a plurality of flaps integral with the tubular portion and located at a distal end of said tubular portion, said flaps being molded in a first position, said flaps in said first position extending toward each other and away from said distal end into said tubular portion and said flaps having lengths such that an opening is formed for allowing lubricating material to be inserted into the guide through said opening after the catheter has been inserted partially into the tubular portion, said flaps being manipulatable by the catheter into a second closed position, the length of said flaps allowing said flaps to abut one another for preventing contamination of the catheter as said guide enters a urethra and said flaps being manipulatable by the catheter into a third position with said flaps extending out of said tubular portion for permitting the catheter to pass therethrough.
Claim 2
Dependent Claim
185 words
A catheter guide for use in inserting a catheter through a urethra into a bladder comprising a molded one-piece device of resilient material having a tubular portion of a predetermined length which is insertable partially into the urethra, and a plurality of flaps integral with the tubular portion and located at a distal end of said tubular portion, said flaps being molded in a first position, said flaps in said first position extending toward each other and away from said distal end into said tubular portion and said flaps having lengths such that an opening is formed for allowing lubricating material to be inserted into the guide through said opening after the catheter has been inserted partially into the tubular portion, said flaps being manipulatable by the catheter into a second closed position, the length of said flaps allowing said flaps to abut one another for preventing contamination of the catheter as said guide enters a urethra and said flaps being manipulatable by the catheter into a third position with said flaps extending out of said tubular portion for permitting the catheter to pass therethrough.
Claim 3
Dependent Claim
33 words
A catheter guide according to claim 1, wherein said flaps are reduced in thickness increasing the flexibility of said flaps as the catheter is manipulated through the guide as it enters a urethra.
Claim 4
Dependent Claim
49 words
A catheter guide according to claim 1, wherein said flaps are initially molded so that one flap is longer than another and the longer flap lies beneath and is spaced from the other flap so that the lubricating material can be inserted into the distal end of the guide.
