Embodiment Construction

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] see figure 1 , figure 1 Shown is an embodiment of the present invention, which specifically includes a urinary bladder (ie, a first cavity) with a volume of about 300-350ml, and a buffer bladder (ie, a second cavity) for preventing urine reflux. The upper end of the buffer bag is divided into two convex hollow tubular joints with a length of about 2cm and a diameter of about 8mm. The volume of the buffer sac is 15-20ml, which is located between the ureter and the first cavity, and separates the two. The one-way first anti-reflux valve is connected between the buffer sac and the urinary sac, that is, urine can only flow from the buffer sac to the urinary sac.

[0024] Preferably, a first anti-reflux valve is arranged between the second cavity and the first cavity, the valve is composed of two petal-like valves, and the protruding part faces the first cavity. The ...

Abstract

The upper end of a first cavity is respectively communicated with a left ureter and a right ureter of a human body, the lower end of the first cavity is communicated with a urination port, a second cavity is arranged between the ureters and the first cavity, and a one-way urine delivery port is arranged between the second cavity and the first cavity; an interlayer is arranged between the outer layer of the first cavity and the internal storage, the interlayer is filled with gas, and the third cavity is communicated with the gas through a guide pipe. The second cavity is additionally arranged between the ureter and the urine of the artificial bladder, and the one-way urine conveying opening is formed, so that backflow of urine is avoided, and damage to the kidney and urinary tract infection are reduced.

Description

technical field [0001] The invention relates to a medical artificial organ, in particular to an artificial bladder with a simple structure and convenient operation that can prevent reflux, so as to realize the automatic urination function of the natural bladder. Background technique [0002] Bladder cancer is a malignant tumor that occurs in the bladder mucosa and is one of the most common tumors in the genitourinary system. The treatment of bladder cancer is mainly surgery, and radical cystectomy remains the gold standard for the treatment of invasive bladder cancer and recurrent high-risk non-invasive bladder cancer. [0003] Currently, there is no standard solution to the problem of urinary diversion after radical cystectomy. The ideal urinary diversion should meet the requirements of low postoperative complications, protection of renal function, and high quality of life of patients. Radical cystectomy is invasive and prone to complications after surgery, which seriousl...
