Description

Automatic discharge type ureteral stent tube
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the field of medical equipment, concretely relates to automatic discharge formula ureteral stent pipe.
[ background of the invention ]
The ureteral stent is a plastic tube with side holes bent at two ends with different lengths, and is widely applied to postoperative urinary system diseases, and can effectively drain urine and prevent ureter stenosis when being placed in a ureteral tube due to the internal support and internal drainage functions, thereby being beneficial to discharge of broken stones and pus and recovering the functions of the affected side kidney. Although traditional ureteral stent tube can carry out simple drainage effect, but there is certain problem during practical application, can not realize automatic interception effect when palirrhea urine flows in the bladder toward the kidney in to lead to patient's kidney to receive secondary damage, influence patient health, in case stent tube fixes in patient ureter, treat to support the drainage and accomplish the back, take out and still need face invasive operation problems such as cystoscope, the result of use is relatively poor, need improve.
[ Utility model ] content
In order to achieve the above purpose, the utility model adopts the technical proposal that:
