32 results about "Artificial bladder" patented technology

The invention provides a simulation and analysis device for physiological processes of urine storage and emiction of the bladder, comprising an artificial bladder, an artificial urethra, a pelvic cavity sink, an extrusion device, a pressure device, a perfusion device, a urine recovery device, a pressure measuring device and a flow metering device. The artificial bladder is used for simulating thefeature that the bladder changes volume along with the liquid capacity and realizing the function of urine storage; the artificial urethra used as a channel for discharging liquid in the bladder; thepelvic cavity sink is used as the environment for containing organs of the bladder, and the like; the extrusion device is used for simulating extrusion caused by the peripheral organs of the bladder to the bladder; the pressure device is used for simulating the shrinkage of detrusor of the bladder so as to realize the function of emiction of the bladder; the perfusion device is used for accurately measuring and displaying the liquid amount perfused to the bladder in real time; the urine recovery device is used as liquid reserve of liquid pumping of the perfusion device and for collecting the liquid discharged from the urethra so as to facilitate recycling; the pressure measuring device is used for measuring and displaying inner pressure of the bladder and the inner pressure of a pelvic cavity in real time; and the flow metering device is used for measuring and displaying the flow of the liquid passing through the urethra in real time. The invention can realize the physiological processes of urine storage and emiction of the artificial bladder, analyzes the physiological process by controlling and monitoring urine dynamical parameters of bladder volume.

An in situ artificial bladder endoprosthesis comprising two parts (2, 3) connected to each other; each part (2, 3) comprising a respective resorbable cap piece (4, 3) made of PGA fiber fabric 5) and the respective frames (6, 7) obtained by PGA / PLA copolymer associated with said cap pieces (4, 5); said parts (2, 3) are joined together to define a hermetic enclosure .

Device and method for correcting urinary incontinence and urinary retention, by implanting a urinary flow control device for elective user control of urinary function in male and female patients. The device is a mechanical valve for a natural or artificial bladder, and includes a longitudinally extended housing, preferably attached to the abdominal wall. Preferably a bladder anti-prolapse skirt is attached between the bladder and control valve, and the skirt may repair or replace the bladder. The device provides a urine flow channel that passes through the valve from one side to the other of a valve seat where an actuator with a mating stopper is controlled to open and close the valve at the election of the user with an external controller. The valve is an occlusion type, or a pinch type. Preferably the flow channel is an artificial urethra passing through a pinch valve between stopper and valve seat.

An orthotopic artificial bladder endoprosthesis includes a first portion connectable to a urethra of a patient and a second portion connected to the ureters of the patient; the first portion including a collapsible cover made of a multi-layered silicone membrane having an external surface and an internal surface both coated with pyrolytic turbostratic carbon; the second portion including a resorbable cap including a fabric of PGA fibres and a frame, coupled with the cap, made using PGA / PLA copolymer; the cover and the cap being connected together along their respective edges, to define an enclosure.

The invention relates to an artificial bladder ferromagnetic composite body comprising: a ferromagnetic substrate and a coating coating wrapped on the ferromagnetic substrate; the ferromagnetic substrate includes the following components: organic silica gel, polydimethylsiloxane resin, magnetic Particles, the volume ratio of organic silica gel to polydimethylsiloxane resin is (4-10): 1, and the volume fraction of magnetic particles in the ferromagnetic matrix is ​​20-40%; the coating includes the following components: organic Silica gel and brightener, the mass ratio of organic silica gel to brightener is (1.0~2.0):1. The artificial bladder ferromagnetic composite can be used as the actuation source of the magnetically driven soft bladder pump, benefiting from the high coercive force and distributed actuation source of the permanent magnetic particles in the ferromagnetic composite, the ferromagnetism shows reliable actuation, and at the same time A large amount of magnetic force is output to act as an artificial detrusor muscle to squeeze and empty the bladder.
