Abstract

Hydrophobic and lipophobic technology is adopted to form complementary structure in nanometer size on the surface of some material and some air atoms are adsorbed on the surface to form one stable air film. The nanometer material for artificial urinary bladder has hydrophobic and lipophobic surface and thus the lotus leaf-like surface function, so no water and other dirt likely to produce post-operation complication contact with the surface of artificial urinary bladder. The artificial nanometer urinary bladder has certain elasticity and contraction capacity and thus excellent urine storing function and timely urine excreting function, so that it may be used as excellent substituting urinary bladder.

Description

[0001] Technical field: The present invention relates to an artificial bladder made of artificial nanomaterials, which belongs to the field of artificial organ manufacturing. Background technique:

[0002] 1. At present, urinary diversion is necessary after total bladder resection in the treatment of advanced bladder cancer, and the main method of urinary diversion is to replace the function of the original bladder with an artificial bladder. The manufacture of the existing artificial bladder: cut a long section of intestines from the patient himself to make a bladder that can hold about 300-500ml of urine. Its shortcomings: not only seriously interfere with the digestive tract, but also physiologically very different from the urinary tract. Therefore, there are many postoperative complications, including intestinal leakage, urinary leakage, mucus in the artificial bladder, stones, alkalosis, etc., and the surgical trauma is large, the recovery is slow, and the quality of life...

Embodiment Construction

[0009] The artificial nano-bladder is composed of ureteral interface 1, urinary bladder bag 2 and urethral interface 3. The artificial nano-bladder is made of non-toxic, non-absorbable chemical fiber, silk, velvet or blended and other elastic materials such as bladder-like bladder bag, such as polyester Acrylonitrile nanofiber, with a capacity of about 300-500ml, contains an anastomosis connected with the urethra (about 1.5-2cm in diameter) and ureter (about 0.8-1.2cm in diameter), and the inner surface is treated with super-amphiphobic technology. Insert the original bladder to make it have a good urine storage function, and avoid complications such as bladder stones, urine leakage, electrolyte imbalance, etc., and satisfactorily replace the bladder. The method of making artificial nano-bladder from chemical fiber, silk, velvet or blended and other elastic materials: super-amphiphobic technology is used on the surface of the material to build a structure with complementary nan...
