Abstract
The utility model relates to an artificial bladder made of artificial nanometer materials. The utility model uses super-amphiphobic technology to build a structure having complementary nanometer size geometric shapes on the material surface. The structure causes the low concave surface of nanometer size to absorb gas atoms which exist stably to form a layer of stable gas thin film. The utility model has the advantages that because the material surface of the artificial nanometer bladder has super-amphiphobic performance, the artificial nanometer bladder has the surface function of a 'lotus leaf', and thus, oil, or water, or sewage can not directly contact the material surface, and the complications can be caused after operations; because the artificial nanometer bladder has definite elasticity and contractibility, the artificial nanometer bladder not only has a favorable urine storage function, but also has the function of irregular urination, and the complications, such as vesical calculus, urine leakage, electrolyte disturbance, etc., can be effectively avoided. The utility model is a satisfactory substitute for human bodies' bladders.
Description
Technical field: this utility model relates to a kind of artificial urinary bladder that adopts the artificial nano material, belongs to artificial organ and makes the field.
Background technology:
1, necessary urinary diversion after treatment bladder cancer in late period is done full wing excision at present, and the main method of urinary diversion is the function that replaces original bladder with artificial urinary bladder.The making of existing artificial urinary bladder: cut long section intestines patient self and make a storage allantois that can hold about 300～500ml urine.It is not enough point: not only seriously disturb digestive tract, and also far from each other with urinary tract on physiology.Therefore, postoperative has many complication, comprise that intestinal leaks, urinates the mucus of leakage, artificial urinary bladder, calculus, alkalosis or the like, and operation wound is big, recovery is slow, and the quality of life or the life quality of postoperative patient are poor.
2, utilize the histiocyte engineering to cultivate the technology of reproducing bladder, still be in conceptual phase at present, it is clinical also premature to be applied to.
3, publication number CN1339290A, title " intelligent in-situ implanted artificial bladder ".This artificial urinary bladder is carried by urine and storage system----is made up of artificial ureter button loop, artificial urinary bladder body, artificial urethra button loop; Intelligence automation system----is by the pressure sensitive alarm device, and the anti-reflux device is urinated pump and controller and formed automatically.It is not enough point: the one, complex structure, poor reliability; The 2nd, postoperative easily causes complication such as vesical calculus, can't replace the function of former human body bladder.
Summary of the invention:
Purpose of design of the present utility model: avoid the weak point in the background technology, utilize material artificial urinary bladder through nanotechnology treatments, the one, the destructiveness of avoiding performing the operation to intestinal is hit, and significantly reduces operation wound; The 2nd, enable to replace satisfactorily the function of former human body bladder.
Design of the present utility model: super two thin technology are to build the complementary structure of nano-scale geometry on material surface.Owing to can make adsorbed gas atom stable existence on the surface of nano-scale indentation, so on macro surface, be equivalent to the gas membrane that has one deck stable, this gas membrane can't directly contact oil, water or dirt in material surface, thereby make material surface present ultra-amphosphobic, promptly possess the function of surface of " Folium Nelumbinis ".This technology does not change the performance of original material, even has also increased effects such as sterilization, mildew-resistant.Its technical scheme: 1. a kind of artifical nano-urinary bladder, artificial urinary bladder adopt nano material to make.2. a kind of manufacture method that will super two thin technology be used for artifical nano-urinary bladder, adopt super two thin technology to build the complementary structure of nano-scale geometry on the artificial urinary bladder material surface, this structure makes the surface adsorption gas atom stable existence of nano-scale indentation, and forms the stable gas membrane of one deck in the nanometer bladder surfaces.
This utility model is compared with background technology, the one, artifical nano-urinary bladder is because its material surface presents ultra-amphosphobic, the function of surface that promptly possesses " Folium Nelumbinis " therefore can't directly contact oil, water or dirt in material surface, and postoperative can not cause complication such as vesical calculus; The 2nd, because artifical nano-urinary bladder has certain elasticity and contractility, not only possessed good storage urine function, uncertain urinary function, and avoid vesical calculus, complication such as urine leakage, electrolyte disturbance effectively, it is human bladder's satisfied succedaneum, and patient utilizes insufflation pressure to finish to urinate after surgery, fundamentally removed the storage urine that postoperative patient exists for a long time, the difficult difficult problem of urinating, and has solved that medical circle is wanted to solve for a long time and the difficult problem that not have solution; The 3rd, the employing of artifical nano-urinary bladder, eradicated thoroughly that background technology exists: intestinal leaks, urine leaks, the mucus of artificial urinary bladder, calculus, alkalosis, operation wound are big, it is slow to recover, the quality of life of postoperative patient or life quality difference or the like drawback, the quality of life and the life quality of postoperative patient have fundamentally been improved, the quality of life of its postoperative patient is compared with background technology with life quality, has improved nearly 8 percentage points.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Artifical nano-urinary bladder is by ureter interface 1, storage allantois bag 2 and urethra interface 3 constitute, artifical nano-urinary bladder adopts nontoxic, the non-absorbent chemical fibre of human body, silk, material bladder sample capsule bags such as floss or blending and other elasticity, as the polyacrylonitrile nano fiber, about 300～the 500ml of its capacity, contain and urethra (diameter about 1.5～2cm) and the ureter (anastomotic stoma that diameter about 0.8～1.2cm) is connected, inner surface is through super two thin technical finesses, former bladder position is implanted in the sterilization back, make it possess good storage urine function, and avoid vesical calculus, urine leaks, complication such as electrolyte disturbance, the satisfied bladder that replaces.The method of material artifical nano-urinary bladders such as chemical fibre, silk, floss or blending and other elasticity: adopt super two thin technology to build the complementary structure of nano-scale geometry on the material surface, this structure makes the surface adsorption gas atom stable existence of nano-scale indentation, and forms the stable gas membrane of one deck in the nanometer bladder surfaces.Adopt material bladder capsule bags such as chemical fibre, silk, floss, blending or polyacrylonitrile, super two thin technical finesses are adopted on its surface.
Here need to prove: the manufacturing of medical nano material is a prior art, is not described in detail at this; And super two thin technology, full maturity at present is so be not described herein at this.
Claims (3)
1, a kind of artifical nano-urinary bladder is characterized in that: artificial urinary bladder is made of ureter interface 1, storage allantois bag 2 and urethra interface 3 and adopts nano material to make.
