This utility model relates to a kind of succedaneum that is used for human body, particularly a kind of artificial urinary bladder device.
In order to remove the misery of suffering from the bladder disease patient, the doctor has bladder cancer to do the excision of full bladder and because various bladder pathological changes to favour in the hospital, the patient who causes the bladder function forfeiture can not store up urine, urinary function normally can adopt the artificial urinary bladder device to substitute.At present, existing bladder device is a kind of blister cavities body, its shell is not yielding, at capsula interna of capsule cavity inner sleeve, interior cyst wall is thin and soft, make blister cavities form not connected dual chamber, promptly the exocoel between inner chamber and inside and outside cyst wall is implanted auxiliary power unit in implantable artificial bladder device.Auxiliary power unit is made up of water receiver and pump.The inner chamber storage of urine, exocoel links to each other with water receiver through pump.When the discharging urine, push pump, the water in the water receiver is injected exocoel, cyst wall in the outer intracavity hydraulic pressure extruding is discharged the urine in the inner chamber.In the full process of urine, under the spring action in water receiver, the water resorption of the outer intracavity of urine-collecting device makes intracavity form negative pressure to water receiver, impels urine to enter inner chamber through ureter, thereby finishes storage urine and urinary function.But the shortcoming of this artificial urinary bladder device is, also need implant the close with it water receiver of volume in implantable artificial bladder device, and therefore, the space that occupies in vivo is excessive, influences the function of other internal organs in the abdominal cavity.Its complex structure is prone to fault, is difficult to practicability.Because inner chamber is in negative pressure state for a long time and does not also meet kidney and ureter physiology, disturb the normal physiological processes of urinary system and conveying urine.And in the urine discharge process, because the capsula interna wrinkle cause the urine emptying incomplete.
Main purpose of the present utility model provides a kind of improved artificial urinary bladder device, and its structure is the normal bladder of simulation, and is simple in structure, practical, does not need auxiliary power unit can finish storage urine and urinary function; Its moulding meets pelvic cavity and dissects.
This utility model is to achieve these goals by the following technical solutions: a kind of artificial urinary bladder device comprises the blister cavities body, the side of described blister cavities body and transverse section ovalize, its vertical section are the blunt circle of triangle and the long isosceles triangle in base; But the middle part is provided with the barrier film of dipping and heaving in blister cavities, and this barrier film is fornix shape, and blister cavities is divided into two not connected cavitys, i.e. urine chamber and air chamber; The rear side end in urine chamber is provided with two ureter loops, and the other end is provided with the urethra loop, and the ureter loop is the heavy caliber tubular, and an end of air chamber is provided with air conduit.
Below in conjunction with accompanying drawing and preferred embodiment this utility model is described in further detail:
Fig. 1 is a vertical section sketch map of the present utility model, and this figure shows that its vertical section is the triangle blunt rounded.
Fig. 2 is this utility model schematic cross-sectional view.
Fig. 3 is a structural representation in the full process of the present utility model.
Fig. 4 is the structural representation under the full state of the present utility model.
Fig. 5 is the structural representation under the emptying state of the present utility model.
See also Fig. 1 to shown in Figure 5, this utility model comprises: a blister cavities body 1, the side of this blister cavities body 1 and transverse section ovalize, its vertical section is the blunt circle of triangle and isosceles triangle that the base is grown, select for use the bigger silastic material of hardness to make, but the middle part is provided with dipping and heaving barrier film 3 in blister cavities, and barrier film 3 is adopted the lower silicon rubber material of hardness and made, and periphery in the middle part of being adhesively fixed it in blister cavities body 1 with the binding agent of bonding silicone rubber.Be fornix shape under the naturalness, in full accord with the top or the bottom of blister cavities wall, this barrier film 3 is divided into two not connected cavitys with blister cavities, i.e. urine chamber 6 and air chamber 2; The rear side end in urine chamber 6 is provided with two ureter loops 7, and the other end is provided with urethra loop 5.Ureter loop 7 is a tubular, and it has bigger internal diameter, and internal diameter is about 0.70cm, and a mouthful place is bonded with terylene floss cover thereon.One end of air chamber 2 is provided with air conduit 4, by this air conduit 4 it is communicated with air.Urine chamber 6 can change with the capacity of air chamber 2, the two complementation, and the capacity sum of urine chamber 6 and air chamber 2 is equal to the total capacity of blister cavities body 1 under any state.
During actual the use, behind artificial urinary bladder device implant into body, when urethra loop 5 is closed, urine is in ureter input urine chamber 6, along with hydrouria, barrier film 3 is along with rising and since barrier film 3 comparatively softness do not have tangible resistance, and owing to air chamber 2 communicates with air, thereby urine is in continual and steady low pressure (generally at 0-10cm) in filling period.When barrier film 3 rise to blister cavities body 1 on inwall when fitting fully, the urine in the urine chamber 6 reaches heap(ed) capacity, promptly is equivalent to the total capacity of blister cavities body 1, the capacity of air chamber 2 then reduces to zero.The discharging of urine can be adopted the mode that urethra loop 5 is connected with the human body urethra, discharges urine from 2 pairs of barrier films 3 of air chamber certain pressure of exerting pressure, or adopts artificial urethra, and the phase urine chamber of urinating is relative negative pressure.Lasting low pressure and the relative negative pressure of the phase of urinating of urine chamber 6 inherent filling periods help renal pelvis urine through the ureter drain, thereby have protected the normal anatomy and the function of kidney.Along with the discharging of urine, when barrier film 3 dropped to and fits fully with the following inwall of blister cavities body 1, it is maximum that air chamber 2 capacity reach, and urine chamber 6 inner capacitiess reduce to zero, and promptly residual urine is zero.Urine is drained fully, helps keeping the available capacity of artificial urinary bladder device storage urine, the prevention urinary tract infection.
Because the outer wall of artificial urinary bladder device blister cavities body 1 of the present utility model is harder, not yielding behind the implant into body, blister cavities body total capacity is equivalent to the normal bladder under the complete state, because normal bladder and place pelvic cavity anatomic space under the full state of the moulding of blister cavities body simulation are complementary, and help original position and implant.And, make the ureter anastomotic healing good, and have good unobstructed property and anti-reflux function because ureter loop structure reaches and the corresponding methods of anastomosis of ureter.
