Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular, it is especially related to an intelligent urinary incontinence control system. BACKGROUND

[0002] Urinary incontinence is a common disease of the urinary system, especially in the adult female population, and stress urinary incontinence, as the most common type, refers to involuntary leakage of urine due to increased abdominal pressure caused by coughing, laughing, exercise, etc. Current clinical treatment methods include behavior therapy, drug treatment and surgical treatment, etc., but all have certain limitations. For example, although behavior therapy is non-invasive, it needs to be adhered to for a long time, and the effect is greatly affected by individual differences; drug treatment has certain effect on urge incontinence, but the effect on stress incontinence is poor, and may cause dry mouth, constipation and other side effects; surgical treatment has the problems of large trauma, many postoperative complications and high risk of recurrence. Therefore, developing a minimally invasive, intelligent and dynamically adjustable urinary incontinence management device according to the actual situation of patients has become a key problem to be solved in the current medical field.

[0003] Existing intravaginal implantable urinary incontinence devices, such as vaginal pessaries, mainly achieve the purpose of urine control by mechanically supporting the urethra, but there are many technical bottlenecks. First, in terms of pressure control, most of these devices use fixed shape or passive elastic support, which cannot dynamically adjust the pressure in real time according to the change of abdominal pressure, and it is difficult to timely enhance the support of the urethra when the abdominal pressure rises suddenly, thereby leading to unsatisfactory urine leakage control effect. Secondly, in terms of comfort and safety, the materials such as silicone or polyethylene used by the device have relatively high hardness, and long-term wearing can easily compress the vaginal mucosa, causing ischemia, ulceration and other problems, which brings discomfort to patients and increases the risk of infection. In addition, such devices are usually designed with uniform specifications, which cannot fully adapt to the anatomical structure differences of different patients, so that some patients are difficult to continuously use due to device displacement or discomfort, which seriously affects the treatment compliance.

[0004] Part of the existing intelligent urinary incontinence device attempts to achieve pressure regulation by means of elastic structure, but there are still significant deficiencies. On the one hand, only relying on a single urethral pressure sensor for monitoring, it is difficult to accurately capture the dynamic correlation between abdominal pressure and urethral pressure, making the urine control response lag, and unable to respond to urine leakage in time. On the other hand, these devices generally lack intelligent prediction algorithms, and can only take passive measures after a urine leakage event occurs, unable to provide early warning and active intervention, resulting in a large number of urine leakage events that are difficult to effectively avoid. Furthermore, the existing intelligent devices have defects in material selection and structure design, such as the elastic modulus of the elastic arm not being accurately controlled, which can easily cause local pressure to be too high and damage the urethral tissue. At the same time, most devices do not integrate temperature monitoring functions, and cannot provide timely warning of tissue ischemia risk. In addition, the antibacterial treatment on the surface of the device is simple and short-acting, and it is difficult to effectively prevent infection problems during long-term wear. These technical shortcomings seriously restrict the clinical application effect and patient experience of intelligent urinary incontinence management equipment, and urgent need for innovation breakthroughs in multi-sensor fusion, intelligent algorithm optimization, material innovation, and safety monitoring design, to improve the performance and reliability of the equipment.

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0015] Referring to the drawings, the present embodiment provides an intelligent urinary incontinence control system, comprising: The intravaginal implant assembly is made of a biocompatible elastic material, and the main body is a tubular structure, and the tubular body 1 is provided with: A main balloon 2, which is spherical or ellipsoidal after expansion, is adapted to the area around the urethra; here, the main balloon is implanted into the vagina through the auxiliary unit, and is positioned in the middle third to the lower third of the vaginal cavity (close to the rear of the urethra), and the specific position corresponds to the area from the middle segment of the urethra to the lower part of the bladder neck. At this time, the inner side of the main balloon (close to the urethra side) is in contact with the anterior wall of the vagina, and the anterior wall of the vagina is directly adjacent to the posterior wall of the urethra, forming a pressure transmission path of "main balloon → anterior wall of vagina → urethra". After the main balloon is implanted into the vagina, it is fixed at a specific position through image assistance, and the anterior wall of the vagina is used as a medium to indirectly apply support pressure to the urethra without directly entering the urethral cavity, which further avoids damaging the urethral mucosa or causing infection.

[0016] At least one auxiliary balloon 3 in fluid communication with the main balloon 2; A fluid channel 4 connecting the main balloon and the auxiliary balloon, the fluid channel being filled with a biocompatible liquid or gas; A pressure sensing unit arranged on the surface or inside of the main balloon, comprising: A first pressure sensor integrated on the surface of the main balloon in contact with the urethra; the sensitive element part of the first sensor is embedded in the silicone rubber material inside the main balloon, and only the sensing surface is exposed to the side in contact with the urethra, ensuring that the first sensor can accurately and directly collect the urethral closure pressure, so that the first sensor can sensitively perceive the pressure change of the urethral wall caused by factors such as changes in intravesical pressure, voluntary or involuntary contraction of the urethral sphincter, and the data collected directly reflects the actual pressure condition of the urethra maintaining the closed state to prevent urine leakage; A second pressure sensor is arranged outside or at the edge of the main balloon. If the main balloon is ring-shaped, the sensor is usually arranged on the outer circumferential surface of the main balloon away from the urethra, or at the edge of the ring structure; if the main balloon is oval-shaped, it can be located at the outer edge of the long axis or short axis direction. In actual application, this position corresponds to the area near the bladder posterior wall of the vaginal vault. For example, when the main balloon is implanted in the vagina, the second pressure sensor outside the main balloon can effectively capture the pressure signal acting on the outside of the main balloon caused by the change of intra-abdominal pressure (such as the fluctuation of intra-abdominal pressure caused by coughing, laughing, diaphragmatic descent during exercise, abdominal muscle contraction, etc.) conducted to the vaginal wall. Through such a layout of position, the second pressure sensor can monitor the change of intra-abdominal pressure in real time, and provide key data for subsequent comprehensive analysis and decision-making of the system based on the difference between intra-abdominal pressure and urethral pressure.

[0017] A control unit is electrically connected with the pressure sensing unit and is configured to: Based on the data difference of the first pressure sensor and the second pressure sensor, the pressure adjustment amount is calculated by the following formula: Wherein, Pc is the urethral closure pressure, Pi is the intra-abdominal pressure, and α is a static adjustment coefficient (0.8-1.2) and β is a dynamic adjustment coefficient (0.2-0.5); The pressure data is analyzed by a machine learning algorithm and the probability of urinary incontinence risk is predicted : Wherein , , , is a weight coefficient, and b is a bias term, is the pressure fluctuation frequency; A driving unit 8 is connected with the control unit and the fluid channel, including: a micro pump 81 arranged at the fluid inlet of the main balloon; a flow control valve 82 arranged in the fluid channel; through the driving unit arranged, the fluid in the auxiliary balloon can be pumped to the main balloon (or the fluid in the main balloon is pumped out to the auxiliary balloon), so that the main balloon is inflated (or contracted), thereby satisfying the extrusion (or relaxation) of the vaginal wall, and then realizing the control of whether the urine flows out.

[0018] A fixing structure includes: An elastic support frame 5 is fixed on the tube body and arranged around the main balloon, and its shape is adapted to the contour of the inner wall of the vagina after the main balloon is expanded; A plurality of adsorption structures or barb structures are distributed on the outer surface of the elastic support frame, which are used to fix the intra-vaginal implant assembly in the vagina after the elastic support frame is expanded; preferably, the elastic modulus of the elastic support frame is in the range of 5-20 MPa; An auxiliary device is used to send the intra-vaginal implant assembly to a specific position in the vagina and pull it out from the vagina, and the outer surface of the auxiliary unit is lubricated or bionic treated; The integrated block 6 is fixedly arranged at the end of the tube body far from the uterus, and internally arranged with: An energy module provides energy support for the driving unit, and the selection of the battery generally needs to consider volume, capacity, safety, endurance and biocompatibility, such as lithium polymer battery and micro lithium ion battery. A state indication module includes a vibration feedback device, such as a micro vibration motor, which adopts a flat eccentric rotating mass (ERM) motor (size 2x3x1mm) integrated in the integrated block, and transmits information through different vibration frequencies and time lengths. A temperature sensing module is integrated in the main balloon for measuring temperature; here, when the pressure of the main balloon is too high (such as >40 cmH2O) or the time of continuous compression is too long, the blood perfusion of the urethral and vaginal mucosal tissues may be blocked, causing local temperature rise (normal tissue temperature is 36.5-37.5℃, and when ischemic, it can rise above 38.5℃). The temperature sensing module detects the temperature change of the contact interface between the balloon and the tissue in real time, and when the detected temperature is ≥38.5℃, the state indication module is triggered to alarm, and the control unit automatically reduces the balloon pressure (such as releasing 0.3ml of liquid) to avoid tissue damage.

[0025] The traction cord 72 is fixed to the outside of the integrated block and extends out of the vagina. The traction cord 72 extends out of the vaginal opening and can be fixed to the underwear with a pad.
