Description

Technical Field

[0001] The utility model relates to a pet medical device, more specifically, it relates to a veterinary urinary catheter. Background Art

[0002] When a pet undergoes bladder and / or urethra surgery, a catheter will be used during the operation and in the later recovery stage to assist the pet in urinating, and then the catheter will be connected to a drainage bag to collect urine. The urinary tract of a pet is narrow, so the catheter will be designed to be relatively thin; the catheter is not easy to insert into the urinary tract. The doctor will use a metal guide wire when inserting a catheter into the pet. The metal guide wire is first inserted into the catheter, and then the catheter is inserted directly into the bladder. In the prior art, the doctor separates the catheter and the guide wire during the process of inserting the catheter, so the following problems are prone to occur: First, the catheter is easy to fall off during insertion, and after falling off, it is contaminated and is not good for the health of the pet; second, the catheter may be repeatedly inserted and pulled out during insertion, and the guide wire is exposed from the catheter during the insertion, which is easy to cause damage to the animal's urinary tract.
