External artificial urethral sphincter device

Abstract

The present invention discloses an external artificial urethral sphincter device. The external artificial urethral sphincter device comprises a ring-shaped pressure regulating bag fixedly bound on body of a patient, a pump arranged in the ring shape of the pressure regulating bag and communicating with the pressure regulating bag, a hose with one end connected with the pump, and a sleeve bag sleeving the penis of a patient and also connected with the other end of the hose. The sleeve bag comprises an outer layer, an inner layer sleeving the penis of the patient, an inflatable bag arranged between the outer layer and the inner layer, arranged on a lower side of the inner layer and also connected with the hose, a buffer layer arranged between the outer layer and the inner layer, and a penisthrough-hole arranged in the inner layer and used for the penis of the patient to penetrate through. Through the scheme, the external artificial urethral sphincter device has advantages of simple structure, convenient and quick replacement, low investment cost, no surgical trauma, etc., and has very high practical value and popularization value in the technical field of medical devices.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an external artificial urinary sphincter device. Background technique [0002] Sphincter refers to a ring-shaped muscle distributed in the walls of certain lumens in humans and animals, often particularly thickened. In humans, sphincters are found in the digestive tract and urinary system. The sphincter closes the lumen when it contracts and opens the lumen when it relaxes, and is usually in a contracted state. Generally subject to autonomic innervation or hormone regulation. There is an internal urethral sphincter at the junction of the urethra and the bladder, which can close the internal opening of the urethra to prevent urine leakage when contracted. The membranous part of the urethra (urogenital septum) has the external urethral sphincter, which is composed of striated muscles and is controlled by consciousness.

AI Technical Summary

Problems solved by technology

[0004] First, the built-in artificial urinary sphincter device is a foreign body, and if it is placed in the body, there is a risk of foreign body rejection. Once rejection occurs, it must be removed; in addition, it also affects the normal activities of the patient;

[0005] Second, it is prone to mechanical failure. Once a mechanical failure occurs, it needs to be removed by surgery again, and it needs to be repaired or re-inserted with new equipment. The difficulty of re-operation increases the probability of postoperative complications;

[0006] Third, after the internal artificial urethral sphincter device is placed in the body, due to long-term direct compression of the urethra, it is easy to cause urethral ischemia and necrosis, resulting in serious complications such as urethral stricture and urinary fistula, requiring repeated or multiple surgical repairs;

[0007] Fourth, it is easy to be infected concurrently. Once infected, the operation will fail and the device needs to be removed, which makes the operation more difficult;

[0008] Fifth, for patients with a history of urethral repair and reconstruction surgery, or multiple perineal area operations, the implantation effect is poor and the risk is extremely high;

[0009] Sixth, after implantation, the patient can no longer undergo other urethroscopy or open surgery

If other operations are performed, the structure or function of the device will be destroyed, and sometimes it will be forced to be removed, leaving great risks and uncertainties;

[0010] Seventh, it is more difficult for the patient to operate, because it is relatively difficult to master the operation through the skin;

[0011] Eighth, long-term operation separated from the skin will cause risks such as skin infection and necrosis in the operation area, and may cause device exposure in severe cases;

[0012] Ninth, the device is an implanted device, which is expensive and burdens the patient heavily;

[0013] Tenth, repeated operations are poorly formed. For example, if the first operation fails or there is a problem with the device, the second operation is difficult, the effect is poor, and the incidence of complications is greatly increased;
