Description

Box body air tightness detection device and box body air tightness detection method Technical Field The present disclosure relates to a cartridge air-tightness detection device and a cartridge air-tightness detection method for detecting air-tightness of a cartridge of a control cartridge of an in-vivo machine of an automatic urinary incontinence control system. Background Urinary incontinence is more common in the elderly population, and there are some treatment methods, but there are still a large number of patients who have no effective treatment means and can only rely on continuous urinary catheterization or palliative measures such as urine pads and pants, so that the life quality of the patients is seriously reduced, and great trouble is brought to the families of the patients. There is thus a clinical need to develop new urinary incontinence treatment devices. An artificial urinary sphincter apparatus has been developed clinically, which has advantages of not only restoring control over urination, but also urination through the normal urethra, without affecting the anatomy of the sphincter and nearby tissues, and good quality of life for the patient. However, existing artificial urinary sphincter devices also suffer from several drawbacks. For example, existing artificial urinary sphincter devices are less reliable, for example, they may over-stress the urethral tissue in certain situations, thereby causing damage to the urethral tissue. The artificial urinary sphincter apparatus may include an in vitro machine and an in vivo machine, which may be fully implanted inside the body, which may be used to perform the main functions of the artificial urinary sphincter. The external machine can be positioned outside the body, can be used for supplying power to and communicating with the internal machine, and can also complete the control and information display of the internal machine and the prompt alarm function. The in-vivo machine may include a control box, wherein a number of important components of the in-vivo machine are housed in the control box. The tightness of the control box is critical. A control box with defective air tightness may lead to health risks for the user. Disclosure of Invention The object of the present application is to provide a device and a method for detecting the air tightness of a case of a control case of an in-vivo machine of an automatic urinary incontinence control system, in order to ensure the air tightness of the control case in terms of the case. According to a first aspect of the invention, the object is achieved by a cartridge tightness detection device, which constitutes a cartridge for detecting tightness of a control cartridge of an in-vivo machine of an automatic urinary incontinence control system, the cartridge having a bottom and a surrounding side wall and an open side opposite the bottom, a plurality of through-openings being provided in the side wall, the cartridge tightness detection device comprising a cartridge holding fixture, which is configured for holding the cartridge such that the open side of the cartridge is hermetically sealed, and a liquid pool, which is configured for receiving the cartridge holding fixture together with the cartridge held in the cartridge holding fixture and for completely immersing the cartridge, and a gas input device, which is configured for being hermetically connected with one of the plurality of through-openings and for inputting a gas to the cartridge through the one through-opening, with the remaining through-openings being hermetically blocked. By means of such a cassette gas tightness detection device, the gas tightness of the cassette can be reliably detected, so that the gas tightness of the subsequently assembled control cassette can be ensured in terms of cassettes. In some embodiments, the cassette clamping fixture comprises a base having a flat support surface, on which a gasket is placed, the cassette being capable of being pressed with its open side against the gasket such that the open side of the cassette is hermetically sealed. In some embodiments, the cassette clamping fixture includes a backing plate for placement on the bottom of the cassette and a pressing device configured to press the backing plate toward the cassette. In some embodiments, the extrusion device comprises a screw, wherein the screw is capable of extruding the backing plate by screwing the screw in one direction and is capable of loosening the backing plate by screwing the screw in the opposite other direction. Alternatively, toggle mechanisms are also conceivable for pressing the pad. In some embodiments, the gas input device is configured as a syringe. Alternatively, air pumps, in particular electric air pumps, are also conceivable. According to a second aspect of the present invention, the object is achieved by a cartridge air tightness detection method for detecting air tightness of a cartridge of a control cartridge of an in viv
