Description

An indwelling catheter device for post-prostatectomy

technical field

The utility model relates to a post-operative medical device, in particular to an indwelling urinary catheter device for post-prostatectomy.

Background technique

Transurethral resection of the prostate is an important method for the treatment of benign prostatic hyperplasia. Wound bleeding is a common complication after prostatectomy. The current clinical method for hemostasis after prostatectomy is: use a self-made bandage to tie one end of the three-chambered prostate. The other end of the catheter is tied to one leg of the patient. The patient straightens the leg so that the bandage pulls the fluid-filled balloon of the three-lumen catheter to compress and stop the bleeding. Generally, it is routinely stretched for 12-24 hours after prostatectomy. .

In addition, most patients had more serious bladder irritation symptoms such as frequent urination and urgency before surgery, and these bladder irritation symptoms did not disappear immediately after surgery, but gradually eased after a period of recovery. In the presence of urethral edema, the patient cannot urinate immediately, and the urinary catheter generally needs to be indwelled for 3-6 days. During the indwelling catheter, due to the existence of bladder irritation symptoms, combined with the stimulation of the surgical wound and the urinary catheter, bladder involuntary often occurs. The contraction causes urine to leak from the urethra and urethral space. Repeated leakage of urine requires multiple changes of the changing pads or sheets, which increases the medical workload, increases the discomfort of patients, and brings about contradictions between doctors and patients. In addition to compressing and hemostasis, the currently used self-made bandage pulling balloon can also reduce the leakage of urine from the urethra and urethral space to a certain extent because the urethral balloon presses against the neck of the bladder during pulling. Irregular production, inconvenient use of patients and unreliable traction problems, urine leakage is still inevitable when the balloon is stretched, and it is only stretched for 12-24 hours after the operation, and the possibility of bleeding is reduced. Urine leakage persisted due to unresolved bladder irritation symptoms during 3-6 days of catheterization. Therefore, this method cannot simultaneously solve the problems related to wound bleeding and urine leakage after prostatectomy.

The urine opening 72 can be connected to a drainage bag, and leaked urine can be stored in this step. 12-24 hours after the operation, when there is no obvious bleeding or high bleeding risk on the prostate wound, the position of the urinary catheter fastener 81 and the fastener 82 on the urinary catheter can be adjusted so that the top pressure joint 5 and the protective pad 6 can not be pressed. At this time, due to the presence of bladder irritation symptoms, urine may still leak from the gap between the urinary catheter 1 and the urethra, and the leaked urine collection member 7 is still responsible for collection.

When the rear end face of the top pressing piece 4 is provided with a slit 10 along its inner diameter direction and along to the urinary catheter fastener 81, the top pressing piece 4 and the urinary catheter fastener 81 are sequentially sheathed on the urinary catheter 1 from the urine outlet end to the urine inlet end. On the urinary catheter 1, since the effect of the urinary catheter fastener 81 remaining fixed on the urinary catheter 1 is weaker than the previous embodiment without opening the crack 10, the role of the reinforcing member 82 is relatively important, and the reinforcing member 82 is preferred at this time. It is a detachable collar with a buckle. After the urinary catheter fastener 81 is sheathed on the urinary catheter 1, the fastener is opened, and then the fastener 82 is sheathed on the urinary catheter fastener 81 and fixed with the fastener. The rest of the implementation process is the same as before.
