Power device for bladder activity auxiliary device

Abstract

The invention discloses a power device for a bladder activity auxiliary device. The power device comprises a storage cavity and a power pump, the storage cavity is used for storing highly-compressed power gas, the power pump is arranged in the storage cavity, a circulation opening is formed in the wall of the storage cavity, connected to an external air bag through a guide pipe and communicated with the air bag each other, straining signals inputted by the outside of the power pump drives power gas to be injected into the air bag, so that the air bag is expanded towards a detrusor to extrude and contract the detrusor, the storage cavity comprises an elastic air storage bag, one surface of the elastic air storage bag wraps the outer wall of a bladder, and the circulation opening is an opening of the air storage bag. According to the power device for the bladder activity auxiliary device, the storage cavity is set into a contracted air storage bag, the volume of the storage cavity is effectively and uniformly dispersed onto the outer wall of the bladder by the air storage bag, excessive space of a pelvic cavity cannot be occupied, and the power device is effectively applicable to auxiliary contraction of the bladder detrusor.

Description

technical field [0001] The invention relates to a device for assisting in improving bladder motility, in particular to a power device of a bladder motility assisting device. Background technique [0002] Underactive Bladder (UAB) is a common clinical syndrome of bladder dysfunction. It is mainly caused by the low activity of the detrusor muscle of the bladder. This is followed by central or peripheral denervation leading to low bladder activity. Clinical manifestations mainly include urinary strain, dysuria, slow urine flow, urinary weakness, intermittent urination, dribbling, prolonged bladder emptying time and / or incomplete bladder emptying, followed by urinary retention, filling incontinence, recurrent urinary tract infection , bladder stones and other manifestations and complications such as ureters and kidneys and other upper urinary tract. [0003] UAB usually has a decrease in bladder sensation and bladder contraction power during the filling phase. When UAB is seve...

Problems solved by technology

Due to its complex pathogenic factors and diverse pathological mechanisms, including non-mechanical bladder outlet obstruction, detrusor hypoactivity, detrusor no contraction, and bladder sensation weakened or absent, as well as urethral sphincter and pelvic floor muscle dysfunction, etc., currently In terms of treatment, in addition to indirectly reducing bladder outlet resistance and increasing bladder emptying or self-intermittent catheterization, there is no recognized particularly effective treatment in the industry to strengthen the contraction power of bladder detrusor, improve bladder emptying, and relieve symptoms. There is a power pump installed between the water bag and the water storage chamber, and then the power pump drives the water to circulate between the water bag and the water storage chamber to achieve the effect of simulating the contraction and relaxation of human muscles. However, if the above simulation If the muscle is directly applied to the contraction of the bladder detrusor, the water storage chamber and the power pump are placed next to the bladder, and the water bladder is placed between the bladder detrusor and the serosa layer, and then connected and communicated with the water bladder through a catheter and the water storage cavity, because the bladder cavity has a large volume, so when the auxiliary detrusor contraction is required, the water in the water storage cavity needs to be injected into the water bladder through the power pump, and then the water bladder is filled. The inner cavity of the detrusor muscle of the bladder, so the overall water volume is at least larger than the inner cavity of the bladder, and the volume of the corresponding water storage cavity is also larger than the inner cavity of the detrusor muscle of the bladder, so it is equivalent to the human bladder in the pelvic cavity. Adding a bladder to the position, and accommodating two bladder-sized objects in the pelvic cavity will result in space limitation or extrusion effect, which will cause symptoms and even complications in the lower abdomen. Even if it is barely accommodated, it is easy to squeeze and affect other tissues in the pelvis or organ, so the existing method of simulating the detrusor muscle is not well suited for assisting bladder motility
