Problems solved by technology

Corresponding extracellular matrix and frame are attached to the inner layer of the urine delivery and storage system. After implantation in the body, urothelial cells can grow along the wall, thus successfully solving the problem of ureteral anastomosis due to granulation tissue hyperplasia and fiber wrapping. The resulting obstruction problem can prevent hydronephrosis and effectively protect kidney function, and can successfully solve the problem of urinary salt deposition and urolith formation caused by long-term contact of polymer chemical materials with urine

Embodiment Construction

[0009] See the attached picture: the intelligent orthotopic implantable artificial bladder in the picture consists of the following parts:

[0010] a. Urine delivery and storage system: composed of artificial ureteral loop 1, artificial bladder body, and artificial urethral loop;

[0011] b. Intelligent automation system: It consists of a pressure sensing alarm device 5, an automatic anti-reflux device 2, 6, a urine pump 7 and its controller.

[0012] C. The artificial ureteral loop and the artificial bladder body have an inner layer 4 attached to the extracellular matrix and its frame; the artificial urethral loop has an inner layer attached to the urine extracellular matrix and its frame, and the automatic anti-reflux devices 2 and 6 are respectively located The artificial ureteral loop enters the artificial bladder body and the artificial bladder body enters the artificial urethral loop, and the urine pump is located in the artificial urethral loop.

[0013] The artificial...

Abstract

The intelligent in-situ implanted artificial bladder consists of urine conveying and storing system and automatic intelligent system, the former includes artificial ureter, artificial bladder body and artificial urethra; and the latter incldues pressure sensing alarm, automatic flow returning mechanisms, urine pump and controller. The present invention is used mainly for patient needling bladder reconstruction and urethra reformation owing to bladder tumor, necrotic and interstitial cystitis, traumatic bladder damage, etc. After the body's bladder is ablated, the artificial bladder is in-situimplanted into the pelvic cavityk, the artificial ureter is anastomosed with the ureter stump, the artificial urethra is anastomosed with the urethra strump, and the urine conveying and storing system is reconstructed. The present invention makes it possible for the patient to control urination time autonomously.

Description

(1) Technical field [0001] The invention relates to a medical artificial organ. Specifically, it is an intelligent model suitable for patients with bladder tumors, necrotizing and interstitial cystitis, severe tissue defects caused by bladder trauma, tuberculous bladder contracture and congenital deformities, etc., who need bladder reconstruction and urinary diversion. In situ implantable artificial bladder. (2) Technical background [0002] At present, permanent urinary diversion and bladder reconstruction mainly adopt ureterocutaneous ostomy and various intestinal replacement bladder operations. The disadvantages are as follows: 1. The incidence of infection is high, especially the retrograde infection from the ureter to the tight glenoid; 2. .There are acid-base imbalance and electrolyte disorder, such as hyperchloric acid interaction, hypokalemia, hypomagnesemia; 3. Malignant tumors may occur in the replacement bowel used; 4. Due to obstruction, urine reflux, residual u...
