Urinary catheterization cannula for clinical use in urology

Abstract

The invention discloses a urinary catheterization cannula for clinical use in urology. The cannula comprises a catheter, wherein a connecting pipe is connected to the left end of the catheter in a transitional manner; the inner diameter of the connecting pipe is smaller than that of the catheter; an airbag is wrapped on the outer curved surface of the connecting pipe; a pipe head is arranged at the left end of the connecting pipe; a side hole is formed in the side surface of the pipe head; and a conical pipe is fixed to the right end of the inner cavity of the catheter. The urinary catheterization cannula for clinical use in urology is simple in structure and convenient to use, and the inner cavities of the catheter, the pipe head and the urinary catheter are communicated to lead out urine; by the arrangement of the inflatable airbag, the cannula is convenient to position and is not easy to slide out; the airbag shrinks in the concave position where the connecting pipe is positioned,so that the outer diameter of the catheter is not increased; and when the cannula is placed, steel wires are placed in a pressurizing pipe, so that the overall toughness of the catheter can be increased to a certain extent, distortion of the catheter in the insertion process is avoided, the success rate of the placement is improved, the pain and discomfort of a patient are reduced, and the successrate of the surgery is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a catheter for clinical use in urology. Background technique [0002] Urinary catheterization is often used for urinary retention, retaining urine for bacterial culture, accurately recording urine volume, understanding the causes of oliguria or anuria, measuring residual urine volume, bladder capacity and cystometry, injecting contrast medium, washing the bladder, and detecting urethral abnormalities. No stenosis and preoperative preparation of pelvic organs, etc. Before radiography and detection, the urine in the bladder needs to be drained. For patients with dysuria, catheterization is required for auxiliary operations, and it is inconvenient to perform catheterization The operation is easy to twist, and the air bag at the front end of the intubation also increases the difficulty of insertion, which is likely to cause pain to the patient.
