Description

An automatic control device suitable for urethral sphincter disorder and its application

technical field

The invention relates to the field of medical equipment, in particular to an automatic control device suitable for urethral sphincter disorders and its application.

Background technique

Due to physiological dysfunction, accident, disease or surgery, some patients will suffer from urethral sphincter injury or dysfunction. With this disorder, patients may face the problem of not being able to control their urination. Some patients can restore the function of the urethral sphincter through continuous muscle exercise and gradually return to normal; however, some patients always face the problem of urinary incontinence, resulting in a decline in the quality of life.

At present, the artificial urethra is an implanted artificial organ that uses a special urethral cuff to wrap around the urethra, and controls the inflation and deswelling of the urethral cuff by a fluid storage bag and a control pump, thereby realizing normal urination function. The cuff is placed in the posterior urethra during the procedure. Squeeze the control pump when you need to urinate, so that the liquid in the cuff flows to the storage bag, and the urethra is opened after the liquid in the cuff is emptied; after urination, the liquid automatically flows into the cuff by the elastic retraction of the pressure-adjusting balloon until it reaches the system The internal pressure is balanced and the urethra is closed. At present, the control pump that controls the flow of liquid is operated by manual mechanical pressing. However, manual operation will bring some inconvenience in actual use. If it is changed to automatic control, it will bring a lot of convenience.

However, it is more difficult to change from manual control to automatic control. First of all, medical applications are more focused on safety. Traditional manual equipment is passive equipment, while automatic control equipment contains electromagnetic devices and is active equipment. Active equipment needs to consider factors such as electromagnetic compatibility, electrical safety, radiation, and various incidental interferences, and it needs to be used with extreme caution; secondly, multiple components are required to realize automatic control, and if it is large in size, human body needs to be monitored. Destructive operations can only be installed, which increases user pain and is difficult to promote.

After retrieval, the Chinese invention patent application number is 200610024984.2, which involves a feedback-controlled anal artificial sphincter system, through external wireless energy supply and wireless communication technology, to realize the complete internal part of the body, and fundamentally eliminate the possibility of infection through the skin Through micro-sensing and other technologies, the detection and display of fecal reserves in the intestine, alarm prompts, and automation of detection and control enable patients to have normal defecation functions and greatly improve their quality of life. But it's an anal artificial sphincter system, and it's ultimately controlled by a manual button. This invention is applied to the internal sphincter and cannot be applied to the urethral sphincter; it uses energy storage capacitors to provide energy, which stores less electric energy and will face the dilemma of frequent charging; the sensor body is installed far away from the controller, reducing the The signal-to-noise ratio is improved, but the circuit connection complexity is increased.
