Urethral catheterization device for urinary surgery

Abstract

The invention relates to the technical field of medical instruments, and discloses a urinary catheterization device for urinary surgery, which comprises a urinary catheter and a urinary catheterization bag, one end of the urinary catheter is respectively connected with a urinary catheterization cavity, a flushing cavity and an inflation cavity through connecting parts, and the other end of the urinary catheter is connected with the urinary catheterization bag through a hose. An adjusting disc and a flow dividing disc are arranged in the urine guiding cavity, and the adjusting disc is close to an opening of the urine guiding cavity. Urine is shunted through the shunting ports in the shunting disc, the urine enters from the small holes of the shunting ports in the shape of the circular truncated cone and then is discharged from the large holes, on one hand, some large-particle impurities in the urine can be removed, blocking in the catheter is prevented, on the other hand, the pressure difference can be increased, the flow speed of the urine is higher, and therefore the catheterization speed is increased; the thin sheet slowly floats along with the weakening of the impact force, so that the liquid inlet area of the liquid inlet is reduced, a pressure difference is formed on the two sides of the adjusting disc, and the flow rate of urine can be increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheterization device for urological surgery. Background technique [0002] Urology is a hospital department that mainly diagnoses and treats some diseases of the "surgery" of the urinary system. It mainly treats various urinary diseases, and the scope of treatment mainly includes various urinary stones and complex kidney stones; kidney and bladder tumors; benign prostatic hyperplasia and prostatic hyperplasia Inflammation; Inflammation and tumor of the testis and epididymis; Hydrocele of the spermatic cord of the testis; Various urinary system injuries; Congenital malformations of the urinary system such as hypospadias, cryptorchidism, hydronephrosis caused by ureteropelvic junction stenosis, etc. Urinary catheter is a pipeline made of natural rubber, silicone rubber or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. A...

Problems solved by technology

[0003] In urological surgery, it is often necessary to use a catheterization device. The catheterization process in the operation includes processes such as inflation, catheterization and flushing. There are many problems in the existing catheterization device. The speed is slow and the catheterization efficiency is low, which affects the operation; when the catheterization is over, the catheter bag is easy to flow back into the catheter
