Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressure detection, in particular to a pelvic floor pressure detection device. BACKGROUND

[0002] In a conventional pelvic floor pressure detection device, a single capsule is mainly used as a main detection capsule. The capsule is filled with fluid inside, and a pipeline is used to connect the capsule with a pressure sensor and a driving pump for adjusting the amount of fluid in the capsule. When the human body touches the capsule, the muscle contraction of the human body will push the capsule to deform, so that the fluid in the capsule transmits the pressure to the pressure sensor through the pipeline to realize the function of pelvic floor pressure detection. However, the method of using the capsule for pelvic floor pressure detection has the problem of inaccurate pelvic floor pressure detection. SUMMARY

[0003] Therefore, the present application provides a pelvic floor pressure detection device to solve the problem of inaccurate pelvic floor pressure detection.

[0004] In a first aspect, the present application provides a pelvic floor pressure detection device, which comprises a first flexible capsule, a first pressure detection device, a first pressure adjusting assembly and a controller.

[0005] The first pressure detection device and the first pressure adjusting assembly are respectively connected with the first flexible capsule. The first pressure detection device is used to detect the pressure in the first flexible capsule, and the first pressure adjusting assembly is used to adjust the amount of fluid of the first fluid in the first flexible capsule to adjust the pressure in the first flexible capsule.

[0006] The controller is connected with the first pressure detection device and the first pressure adjusting assembly respectively. During the detection process, the controller is used to control the first pressure adjusting assembly to adjust the amount of fluid of the first fluid in the first flexible capsule until the preset stop condition is met.

[0007] During the detection process, the controller is used to obtain the amount of fluid of the first fluid in the first flexible capsule.

[0008] During the detection process, the controller is also used to obtain the detection pressure of the first pressure detection device, and compensate the detection pressure based on the amount of fluid of the first fluid, so as to determine the pelvic floor pressure.

[0009] In this method, the pressure inside the first flexible bladder is adjusted by the first pressure regulating component to adjust the fluid volume inside the first flexible bladder, so that the first flexible bladder can make good contact with the object being tested. At the same time, during the test, the controller compensates the test pressure of the first pressure detection device according to the fluid volume inside the first flexible bladder to determine the pelvic floor pressure. Therefore, the problem of test pressure deviation caused by different fluid volumes inside the first flexible bladder can be avoided, thereby improving the accuracy of pelvic floor pressure detection.

[0010] In one optional implementation, the controller is used to control the first pressure regulating component to adjust the fluid volume of the first fluid within the first flexible bladder until a preset stop condition is met, including:

[0011] The controller is used to control the first pressure regulating component to adjust the amount of the first fluid in the first flexible bladder and to obtain the detection result of the first pressure detection device.

[0012] If the detection result indicates that the pressure inside the first flexible capsule reaches a pressure threshold, the controller is used to control the first pressure regulating component to stop adjusting the fluid volume of the first fluid inside the first flexible capsule.

[0013] In this method, when the pressure inside the first flexible capsule reaches the pressure threshold, the controller controls the first pressure regulating component to stop adjusting the flow rate of the first fluid inside the first flexible capsule. Therefore, it is possible to ensure that the first flexible capsule makes good contact with the human body as much as possible while avoiding large detection errors caused by the excessive volume of the first flexible capsule.

[0014] In one optional implementation, the controller is used to acquire the fluid volume of the first fluid within the first flexible capsule, including:

[0015] The controller is used to count the adjustment time of the fluid volume of the first fluid in the first flexible capsule;

[0016] The controller is used to obtain the fluid volume of the first fluid based on the adjustment rate and the adjustment duration.

[0017] In this method, the controller can accurately calculate the amount of fluid in the first flexible bladder by statistically analyzing the adjustment time of the fluid volume of the first fluid in the first flexible bladder and the adjustment rate.

[0018] In an alternative embodiment, the device further includes a flow meter disposed between the first pressure regulating component and the first flexible bladder, the flow meter being connected to the controller, the controller being configured to obtain the flow rate of the first fluid based on the flow meter.

[0019] In this method, a flow meter is installed between the first pressure regulating component and the first flexible bladder, so that the fluid volume of the first fluid in the first flexible bladder can be obtained quickly and accurately.

[0020] In one alternative embodiment, the device further includes a shim assembly comprising at least one shim of height, the shim being disposed on a first side of the first flexible capsule, the second side of the first flexible capsule being positioned close to the object being detected.

[0021] In this method, at least one height-elevating element is provided on the first side of the first flexible bladder away from the object being tested. Therefore, the first flexible bladder can be elevated during the testing process to ensure good contact between the first flexible bladder and the object being tested, and to reduce the difference in fluid volume within the first flexible bladder, thereby ensuring the accuracy of pelvic floor pressure testing.

[0022] In one optional implementation, the controller is configured to acquire the detection pressure of the first pressure detection device and compensate the detection pressure based on the fluid volume of the first fluid to determine the pelvic floor pressure, including:

[0023] The controller is used to query a pressure compensation table based on the detection pressure of the first pressure detection device and the fluid volume of the first fluid to obtain the pelvic floor pressure. The pressure compensation table is used to represent the actual pressure corresponding to different fluid volumes in the first flexible bladder under the same detection pressure.

[0024] In this method, a pressure compensation table is pre-constructed to represent the actual pressure corresponding to different fluid volumes within the first flexible bladder under the same detection pressure. This allows the controller to obtain the pelvic floor pressure from the pressure compensation table based on the detection pressure of the first pressure detection device and the fluid volume of the first fluid. Therefore, detection errors caused by different fluid volumes under the same detection pressure can be avoided, ensuring the accuracy of pelvic floor pressure detection. Furthermore, determining the final pelvic floor pressure through table lookup also improves the correction efficiency of pelvic floor pressure to some extent.

[0025] In one alternative embodiment, the device further includes a second flexible capsule, a first side of which is positioned close to the object being detected, a second side of which is positioned close to the first side of the first flexible capsule, and the second flexible capsule is used to contain a predetermined amount of second fluid.

[0026] In this method, a second flexible bladder is positioned on the first side of the first flexible bladder near the object being tested. Therefore, the height of the second flexible bladder can be controlled by the first flexible bladder to ensure good contact between the second flexible bladder and the object being tested. Simultaneously, the second flexible bladder contains a preset amount of second fluid, which keeps the internal volume of the second flexible bladder constant, avoiding detection errors caused by volume differences and thus ensuring the accuracy of pelvic floor pressure detection.

[0027] In one alternative embodiment, the material hardness of the second flexible capsule is less than that of the first flexible capsule.

[0028] In this method, the material hardness of the second flexible capsule closer to the object being tested is lower than that of the first flexible capsule. Therefore, the second flexible capsule can make full contact with the object being tested, ensuring the sensitivity of pressure detection. At the same time, it can keep the first flexible capsule, which is used for elevation during testing, stable.

[0029] In one alternative implementation, the first fluid is different from the second fluid.

[0030] In this method, the first fluid in the first flexible capsule is different from the second fluid in the second flexible capsule, thus reducing the interference of the first flexible capsule on the second flexible capsule during pelvic floor pressure detection.

[0031] In one alternative embodiment, the first fluid is a liquid and the second fluid is a gas.

[0032] In this method, because liquids are more rigid and deform less, while gases are more elastic and deform easily, the first fluid in the first flexible capsule is liquid and the second fluid in the second flexible capsule is gas. This ensures detection accuracy while avoiding interference from the deformation of the first flexible capsule on the detection of the second flexible capsule.

[0033] In one optional embodiment, the device further includes a second pressure regulating component and a second pressure detection device.

[0034] The controller is used to control the second pressure regulating component to adjust the amount of the second fluid in the second flexible bladder to regulate the pressure in the second flexible bladder, and the second pressure detection device is used to detect the pressure in the second flexible bladder.

[0035] In this method, a second pressure regulating component and a second pressure detection device are incorporated into the pelvic floor pressure detection device. Therefore, the flow rate of the second fluid within the second flexible bladder can be precisely adjusted via the second pressure regulating component to maintain a fixed volume within the bladder, thereby reducing the detection error of the pelvic floor pressure. Furthermore, the pressure within the second flexible bladder is accurately detected by the second pressure detection device to accurately determine the pelvic floor pressure.

[0036] In an optional implementation, the controller is further configured to acquire the detection pressure of the first pressure detection device and compensate the detection pressure based on the fluid volume of the first fluid to determine the pelvic floor pressure, including:

[0037] During the detection process, the controller is used to query the pressure compensation table based on the detection pressure of the first pressure detection device and the fluid volume of the first fluid to obtain the target pressure corresponding to the first flexible bladder. The pressure compensation table is used to represent the actual pressure corresponding to different fluid volumes in the first flexible bladder under the same detection pressure.

[0038] The controller is used to determine the pelvic floor pressure based on the sum of the detection pressure corresponding to the second flexible sac and the target pressure corresponding to the first flexible sac.

[0039] In this method, the controller queries a pressure compensation table based on the detected pressure of the first pressure detection device and the fluid volume of the first fluid to obtain the target pressure of the first flexible bladder. Then, based on the sum of the detected pressure of the second flexible bladder and the target pressure of the first flexible bladder, the pelvic floor pressure is determined. Therefore, the deformation of the first flexible bladder can be avoided from affecting the pelvic floor pressure detection of the second flexible bladder, thereby further ensuring the accuracy of pelvic floor pressure detection.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Currently, pelvic floor pressure monitoring devices for external detection are mainly used in conjunction with pulsed magnetic stimulation (PMS) equipment. The principle of PMS equipment is to use a high-voltage alternating current passing through a coil to generate an induced magnetic field. Human neurons in the alternating magnetic field generate induced currents, causing depolarization and nerve excitation. This nerve excitation produces a series of physiological responses, training the pelvic floor muscles through this mechanism. In its application to the pelvic floor, PMS equipment achieves the same goal as electrotherapy devices: stimulating the nerves in the pelvic floor muscles to strengthen them. Because PMS equipment uses a magnetic field for treatment, it eliminates the need for internal electrodes and does not require the user to remove their pants, making it convenient to use.

[0051] However, in conventional pelvic floor applications, pelvic floor pressure is primarily detected through an intracavitary bladder. The main advantage of pulsed magnetic stimulation (PMS) devices is that they do not require removing clothing or using intracavitary electrodes. Therefore, an external pelvic floor pressure detection device is needed in conjunction with the PMS device to improve comfort and convenience. Based on this, in related external pelvic floor pressure detection, a single bladder is mainly used as the primary detection bladder. The bladder is filled with fluid and connected to a pressure sensor and a pump that adjusts the fluid flow via tubing. When the body comes into contact with the bladder, muscle contraction causes deformation, allowing the fluid inside to transmit pressure to the pressure sensor through the tubing, thus achieving the pelvic floor pressure detection function. Specifically, the pelvic floor pressure detection bladder consists of a pressure-sensing bladder and a supporting frame installed inside. The supporting frame supports the pressure bladder, and the pressure-sensing bladder inflates to make contact with the subject, adapting to different subjects.

[0052] However, since different volumes of gas will experience different internal pressure rises under the same deformation, if the height is forcibly and continuously increased to fit the object being tested, the capsule will need to be filled with a larger volume of gas. The pressure intensity value will also decrease as the volume inside the flexible capsule increases, resulting in inaccurate pelvic floor pressure detection.

[0053] Furthermore, due to significant differences in human anatomy, the perineum position varies at different heights when seated. For the pressure measurement capsule to accurately detect pressure values, it needs to be as close to the perineum as possible. Therefore, conventional techniques control the capsule height by adjusting the inflation volume or pressure to ensure good contact between the capsule and the perineum or anus, effectively capturing the deformation of the pelvic floor caused by muscle contraction and ensuring high sensitivity for pelvic floor pressure measurement. However, because the capsule's inflation height is limited, it often cannot adequately fit patients with higher perineal positions, leading to insufficient sensing intensity and inaccurate pelvic floor pressure measurements.

[0054] In view of this, according to an embodiment of the present invention, a pelvic floor pressure detection device is provided. Figure 1This is a structural block diagram of a pelvic floor pressure detection device according to an embodiment of the present invention. The pelvic floor pressure detection device provided in this embodiment includes a first flexible bladder 1, a first pressure detection device 2, a first pressure regulating component 3, and a controller 4. The first pressure detection device 2 and the first pressure regulating component 3 are respectively connected to the first flexible bladder 1. The first pressure detection device 2 is used to detect the pressure inside the first flexible bladder 1, and the first pressure regulating component 3 is used to adjust the flow rate of a first fluid inside the first flexible bladder 1 to regulate the pressure inside the first flexible bladder 1. The controller 4 is connected to both the first pressure detection device 2 and the first pressure regulating component 3. During the detection process, the controller 4 controls the first pressure regulating component 3 to adjust the flow rate of the first fluid inside the first flexible bladder 1 until a preset stop condition is met. During the detection process, the controller 4 acquires the flow rate of the first fluid inside the first flexible bladder 1. During the detection process, the controller 4 also acquires the detection pressure of the first pressure detection device 2 and compensates for the detection pressure based on the flow rate of the first fluid to determine the pelvic floor pressure.

[0055] Specifically, the first pressure detection device 2 and the first pressure regulating component 3 are respectively connected to the first flexible bladder 1 through the first connecting pipe 5. During the detection process, the first flexible bladder 1 senses the deformation of the pelvic floor muscles of the detection object and generates deformation. The fluid inside the first flexible bladder 1 generates pressure changes due to deformation, and the pressure is transmitted to the first pressure detection device 2 through the first connecting pipe 5, thereby realizing the acquisition of pelvic floor muscle pressure signals. Then, the controller 4 performs data acquisition and processing to control the first pressure regulating component 3 and output pelvic floor pressure.

[0056] Specifically, see Figure 2 The first flexible capsule 1 consists of an outer pressure-sensing capsule and a support frame installed inside the pressure-sensing capsule; wherein, the support frame is used to support the pressure-sensing capsule, and the pressure-sensing capsule rises as the flow rate of the first fluid increases.

[0057] The pelvic floor pressure detection device provided in this embodiment adjusts the fluid volume within the first flexible bladder 1 via the first pressure regulating component 3 to regulate the pressure within the first flexible bladder 1, ensuring good contact between the first flexible bladder 1 and the object being tested. Simultaneously, during the testing process, the controller 4 compensates for the detection pressure of the first pressure detection device 2 based on the fluid volume within the first flexible bladder 1 to determine the pelvic floor pressure. Therefore, it avoids the problem of detection pressure deviation caused by different fluid volumes within the first flexible bladder 1, thereby improving the accuracy of pelvic floor pressure detection.

[0058] As one optional implementation, the controller 4 is used to control the first pressure regulating component 3 to adjust the fluid volume of the first fluid in the first flexible bladder 1 until a preset stop condition is met. This includes: the controller 4 controlling the first pressure regulating component 3 to adjust the fluid volume of the first fluid in the first flexible bladder 1 and obtaining the detection result of the first pressure detection device 2; if the detection result is that the pressure in the first flexible bladder 1 reaches a pressure threshold, the controller 4 controlling the first pressure regulating component 3 to stop adjusting the fluid volume of the first fluid in the first flexible bladder 1.

[0059] It should be noted that the height of the first flexible bladder 1 is jointly determined by the first pressure detection device 2 and the first pressure regulating component 3. The first pressure regulating component 3 continuously pushes the first fluid into the first flexible bladder 1. The first flexible bladder 1 gradually rises as the amount of the first fluid increases. After the first flexible bladder 1 touches the human body, it can no longer deform continuously, and the internal pressure of the first flexible bladder 1 changes. When the pressure inside the first flexible bladder 1 reaches the pressure threshold, it indicates that the first flexible bladder 1 has made good contact with the object being tested. The first pressure regulating component 3 stops working, and the first flexible bladder 1 reaches a measurable state. The user contracts the pelvic floor muscles through software or guidance, and the first flexible bladder 1 generates pressure changes. The pressure value is collected by the first pressure detection device 2 to obtain the pelvic floor pressure.

[0060] Specifically, the first pressure regulating component 3 includes a first drive pump and a first switching valve. The first drive pump is responsible for adjusting the flow rate of the first fluid in the first flexible bladder 1 and the first connecting pipe 5, so as to change the volume and internal pressure of the first flexible bladder 1. The first switching valve is responsible for connecting the first flexible bladder 1 and the first connecting pipe 5 to the outside. When starting operation, under the control of the controller 4, the first switching valve is closed, so that the first flexible bladder 1 and the first connecting pipe 5 are sealed, and the first fluid will not leak when the first drive pump is working. When the internal pressure of the first flexible bladder 1 exceeds the preset maximum threshold, the first switching valve opens to release the excess first fluid, ensuring that the internal pressure of the first flexible bladder 1 reaches the set pressure threshold. After the pelvic floor pressure measurement is completed, the first switching valve is opened to release the internal pressure of the first flexible bladder 1. It should be noted that the preset maximum threshold is greater than or equal to the pressure threshold.

[0061] It should be noted that, in actual operation, the pressure threshold can be determined based on the pressure value detected when the first flexible capsule 1 is in good contact with different detection objects. The pressure threshold is used to characterize the degree of fit between the detection object and the first flexible sensing capsule.

[0062] The pelvic floor pressure detection device provided in this embodiment, when the pressure inside the first flexible bladder 1 reaches the pressure threshold, the controller 4 controls the first pressure regulating component 3 to stop adjusting the fluid volume of the first fluid inside the first flexible bladder 1. Therefore, it can make the first flexible bladder 1 as close to the human body as possible while avoiding large detection errors caused by the excessive volume of the first flexible bladder 1.

[0063] Specifically, the controller 4 is used to obtain the fluid volume of the first fluid inside the first flexible capsule 1, including: the controller 4 is used to calculate the adjustment time of the fluid volume of the first fluid inside the first flexible capsule 1; the controller 4 is used to obtain the fluid volume of the first fluid based on the adjustment rate and the adjustment time.

[0064] The pelvic floor pressure detection device provided in this embodiment has a controller 4 that can accurately calculate the amount of fluid in the first flexible bladder 1 based on the adjustment time of the fluid volume of the first fluid in the first flexible bladder 1 and the adjustment rate.

[0065] Furthermore, the device also includes a flow meter disposed between the first pressure regulating component 3 and the first flexible bladder 1. The flow meter is connected to a controller 4, which is used to obtain the flow rate of the first fluid based on the flow meter.

[0066] The pelvic floor pressure detection device provided in this embodiment has a flow meter installed between the first pressure regulating component 3 and the first flexible bladder 1. Therefore, it can quickly and accurately obtain the fluid volume of the first fluid in the first flexible bladder 1.

[0067] Understandably, a flow meter is installed on the first connecting pipe 5 between the first flexible bladder 1 and the first pressure regulating component 3. When the first pressure regulating component 3 adjusts the flow rate of the first fluid in the first flexible bladder 1, the fluid will flow through the flow meter, and the flow rate of the first fluid in the first flexible bladder 1 can be directly measured.

[0068] See Figure 3 As one of the optional implementations, the pelvic floor pressure detection device further includes a shim assembly 6, which includes at least one shim of height. The shim is used to be disposed on a first side of the first flexible bladder 1, and a second side of the first flexible bladder 1 is used to be close to the object being detected.

[0069] The pelvic floor pressure detection device provided in this embodiment has at least one height-raising element on the first side of the first flexible bladder 1 away from the detection object. Therefore, the first flexible bladder 1 can be raised during the detection process to ensure good contact between the first flexible bladder 1 and the detection object, and to reduce the difference in fluid volume within the first flexible bladder 1, thereby ensuring the accuracy of pelvic floor pressure detection.

[0070] Optionally, the shim can be a shim pad.

[0071] It is worth noting that in actual use, the elevation component 6 may include one or more elevation components of different heights. Users can replace the elevation components according to the approximate height of the perineum / pelvic floor of the test subject to ensure good contact between the first flexible bladder 1 and the test subject. This solves the problem of differences in the sensitivity of the first flexible bladder 1 to pelvic floor muscle deformation caused by differences in human body size. At the same time, it can reduce the difference in the amount of fluid in the first flexible bladder 1 for different test subjects, thereby reducing the error in pelvic floor pressure detection and improving the accuracy of pelvic floor pressure detection for perineum / pelvic floor heights of different test subjects.

[0072] Furthermore, the controller 4 is used to acquire the detection pressure of the first pressure detection device 2 and compensate the detection pressure based on the fluid volume of the first fluid to determine the pelvic floor pressure. This includes: the controller 4 is used to query a pressure compensation table based on the detection pressure of the first pressure detection device 2 and the fluid volume of the first fluid to obtain the pelvic floor pressure. The pressure compensation table is used to represent the actual pressure corresponding to different fluid volumes in the first flexible bladder 1 under the same detection pressure.

[0073] The pelvic floor pressure detection device provided in this embodiment pre-constructs a pressure compensation table to represent the actual pressure corresponding to different fluid volumes within the first flexible bladder 1 under the same detection pressure. This allows the controller 4 to obtain the pelvic floor pressure from the pressure compensation table based on the detection pressure of the first pressure detection device 2 and the fluid volume of the first fluid. Therefore, it avoids detection errors caused by different fluid volumes under the same detection pressure, ensuring the accuracy of pelvic floor pressure detection. Furthermore, determining the final pelvic floor pressure by looking up the table also improves the correction efficiency of the pelvic floor pressure to a certain extent.

[0074] It should be noted that, since the applicable height for different test objects cannot be accurately determined, the height of the first flexible bladder 1 after being raised by the elevating component 6 is still difficult to meet the human body's fit perfectly, and a small amount of error still exists. Therefore, based on the raising by the elevating component 6, the fluid volume of the first fluid can be controlled. Since the first pressure regulating component 3 can be calibrated by the unit fluid volume, the fluid volume of the first fluid can be calculated by adjusting the adjustment time of the fluid volume of the first fluid in the first flexible bladder 1 by the first pressure regulating component 3. The pressure measurement error caused by the different volumes can be calculated by the first fluid volume corresponding to the first fluid volume.

[0075] Specifically, the process of detecting pelvic floor pressure using the elevation component 6 and a single flexible bladder is as follows: Based on the actual height requirement, a suitable elevation component is initially selected from multiple height options in the elevation component 6 for preliminary height control. The first flexible bladder 1 reduces the volume of the first fluid through the elevation component. During detection, the controller 4 controls the first pressure regulating component 3 to adjust the volume of the first fluid within the first flexible bladder 1. Upon contact with the detection target, the pressure inside the first flexible bladder begins to rise. When the pressure reaches the pressure threshold, the first pressure regulating component 3 stops, and the adjustment time t is recorded. The volume of the first fluid within the first flexible bladder 1 is calculated based on the adjustment time t and the adjustment rate of the first pressure regulating component 3. The pressure compensation table is consulted using the volume of the first fluid and the detection pressure from the first pressure detection device 2 to correct the currently collected pressure change value, obtaining the true pressure data for determining the pelvic floor pressure.

[0076] It should be noted that the data in the pressure compensation table is calibrated from standard weight. Under different fluid volumes, the same external pressure is used for calibration to obtain different pressure values. Then, under different external pressures, the pressure values ​​for different fluid volumes are calibrated to form the queried pressure compensation table shown below.

[0077] Pressure compensation table

[0078] Detection pressure …… 75 mmHg 75.1 mmHg 75.2 mmHg 75.3 mmHg …… fluid volume V1 …… 74.3 mmHg 74.4 mmHg 74.5 mmHg 74.6 mmHg …… Fluid volume V2 …… 73.2 mmHg 73.3 mmHg 73.4 mmHg 73.5 mmHg …… Fluid volume V3 …… 70.1 mmHg 70.2 mmHg 70.3 mmHg 70.4 mmHg …… ……

[0079] For example, see Figure 4 This is a schematic diagram of a controller detecting pelvic floor pressure according to an embodiment of the present invention. The specific process is as follows:

[0080] Step S11: After activating the pelvic floor pressure detection, drive the first pressure regulating component 3 to adjust the fluid volume of the first fluid in the first flexible bladder 1.

[0081] Step S12: The pressure inside the first flexible bladder 1 is detected by the first pressure detection device 2. It is determined whether the pressure inside the first flexible bladder 1 has reached the pressure threshold. If so, step S13 is executed. Otherwise, step S11 is returned to continue driving the first pressure regulating component 3 to adjust the fluid volume of the first fluid inside the first flexible bladder 1.

[0082] Step S13: Control the first voltage regulating component 3 to shut down.

[0083] Understandably, when the first flexible capsule 1 comes into contact with the object being tested, the internal pressure of the first flexible capsule 1 gradually increases until it reaches the designed pressure threshold, and then the first pressure regulating component 3 stops.

[0084] Step S14: Calculate the adjustment time of the first fluid volume in the first flexible capsule 1, and calculate the fluid volume of the first fluid based on the adjustment time and adjustment rate.

[0085] It should be noted that the adjustment rate is the first fluid output Vcm per unit time of the first pressure regulating component 3. 3 / s.

[0086] Step S15: Collect the detection pressure of the first pressure detection device 2 and record the pressure change value of the first flexible bladder 1 in real time.

[0087] Step S16: Based on the detection pressure of the first pressure detection device 2 and the fluid volume of the first fluid, the pressure compensation table is consulted to correct the detection pressure of the first pressure detection device 2, thereby obtaining the pelvic floor pressure.

[0088] See Figure 5 As another optional implementation, the pelvic floor pressure detection device also includes a second flexible bladder 7, the first side of which is used to approach the object being detected, the second side of which is used to approach the first side of the first flexible bladder 1, and the second flexible bladder 7 is used to contain a second fluid of a preset amount.

[0089] It should be noted that the first fluid and the second fluid can be either gas or liquid.

[0090] Specifically, such as Figure 5 As shown, the first flexible capsule 1 and the second flexible capsule 7 are placed on top of each other. The upper second flexible capsule 7 is the capsule mainly used for detection, and the height of the lower first flexible capsule 1 can be controlled by controlling its volume.

[0091] It is worth noting that in this embodiment, during the process of adjusting the amount of the first fluid in the first flexible capsule 1, the second flexible capsule 7 can be adaptively raised so that the second flexible capsule 7 fits the object being tested, thereby reducing the detection error caused by the second flexible capsule 7 not making proper contact with the object being tested.

[0092] The pelvic floor pressure detection device provided in this embodiment has a second flexible bladder 7 disposed on the first side of the first flexible bladder 1 near the object being tested. Therefore, the height of the second flexible bladder 7 can be controlled by the first flexible bladder 1 to ensure good contact between the second flexible bladder 7 and the object being tested. Simultaneously, the second flexible bladder 7 is used to contain a preset amount of second fluid, which can fix the internal volume of the second flexible bladder 7, avoiding detection errors caused by volume differences, thereby ensuring the accuracy of pelvic floor pressure detection.

[0093] As one of the alternative implementation methods, the material hardness of the second flexible capsule 7 is less than that of the first flexible capsule 1.

[0094] Specifically, the first flexible capsule 1 is made of a softer material that is relatively hard, while the second flexible capsule 7 is made of a softer material that is more flexible.

[0095] In the pelvic floor pressure detection device provided in this embodiment, the material hardness of the second flexible bladder 7, which is closer to the object being tested, is lower than that of the first flexible bladder 1. Therefore, the second flexible bladder 7 can make full contact with the object being tested, ensuring the sensitivity of pressure detection. At the same time, it can keep the first flexible bladder 1, which is raised during testing, stable.

[0096] Furthermore, the first fluid is different from the second fluid.

[0097] Specifically, the first fluid is a liquid, and the second fluid is a gas.

[0098] The pelvic floor pressure detection device provided in this embodiment has the following characteristics: liquid has high rigidity and less deformation, while gas has high elasticity and is easy to deform. Therefore, the first fluid in the first flexible capsule is liquid and the second fluid in the second flexible capsule is gas. This can adapt to the detection height of different detection objects to ensure detection accuracy, while avoiding interference from the deformation of the first flexible capsule 1 to the detection of the second flexible capsule 7.

[0099] Further, see Figure 6 The pelvic floor pressure detection device also includes a second pressure regulating component 8 and a second pressure detection device 9. The controller 4 is used to control the second pressure regulating component 8 to adjust the amount of the second fluid in the second flexible bladder 7 to regulate the pressure in the second flexible bladder 7. The second pressure detection device 9 is used to detect the pressure in the second flexible bladder 7.

[0100] Specifically, see Figure 6 The second pressure regulating component 8 and the second pressure detection device 9 are respectively connected to the second flexible bladder 7 through the second connecting pipe 10.

[0101] Specifically, the second pressure regulating component 8 includes a second drive pump and a second switching valve. The second drive pump is responsible for adjusting the flow rate of the second fluid in the second flexible bladder 7 and the second connecting pipe 10, so as to change the volume and internal pressure of the second flexible bladder 7. The second switching valve is responsible for connecting the second flexible bladder 7 and the second connecting pipe 10 to the outside. When starting operation, under the control of the controller 4, the second switching valve is closed, so that the second flexible bladder 7 and the second connecting pipe 10 are sealed, and the second fluid will not leak when the second drive pump is working. After the pelvic floor pressure measurement is completed, the second switching valve is opened to release the internal pressure of the second flexible bladder 7.

[0102] It is worth noting that during the actual fluid adjustment process, the second pressure regulating component 8 can be activated first to fill the second flexible bladder 7 with the second fluid according to the preset fluid volume. Once the fluid volume of the second flexible bladder 7 reaches the preset fluid volume, the first pressure regulating component 3 can then be activated to fill the first flexible bladder 1 below with the first fluid, thereby increasing the height of the second flexible bladder 7. When it comes into contact with the human body, the pressure inside the first flexible bladder 1 begins to rise. When it rises to the pressure threshold, the adjustment of the fluid volume of the first fluid inside the first flexible bladder 1 is stopped.

[0103] As an optional implementation, when adjusting the fluid volume of the second fluid in the second flexible bladder 7, the target time for the second flexible bladder 7 to reach the preset fluid volume can be determined in advance based on the adjustment rate of the second pressure regulating component 8. If the second pressure regulating component 8 adjusts the fluid volume of the second fluid in the second flexible bladder 7 for the target time, it indicates that the fluid volume of the second fluid in the second flexible bladder 7 has reached the preset fluid volume, and the controller controls the second pressure regulating component 8 to stop adjusting the fluid volume of the second fluid in the second flexible bladder 7.

[0104] As an optional implementation, the pelvic floor pressure detection device is provided with a flow meter between the second pressure regulating component 8 and the second flexible bladder 7. The flow meter is connected to the controller 4, which is used to obtain the second fluid volume based on the flow meter to determine whether the fluid volume of the second fluid contained in the second flexible bladder 7 reaches the preset fluid volume.

[0105] Furthermore, the controller 4 is also used to acquire the detection pressure of the first pressure detection device 2 and compensate the detection pressure based on the fluid volume of the first fluid to determine the pelvic floor pressure, including: during the detection process, the controller 4 is used to query a pressure compensation table based on the detection pressure of the first pressure detection device 2 and the fluid volume of the first fluid to obtain the target pressure corresponding to the first flexible bladder 1. The pressure compensation table is used to represent the actual pressure corresponding to different fluid volumes in the first flexible bladder 1 under the same detection pressure; the controller 4 is used to determine the pelvic floor pressure based on the sum of the detection pressure corresponding to the second flexible bladder 7 and the target pressure corresponding to the first flexible bladder 1.

[0106] The pelvic floor pressure detection device provided in this embodiment uses a controller 4 to query a pressure compensation table based on the detection pressure of the first pressure detection device 2 and the fluid volume of the first fluid to obtain the target pressure of the first flexible bladder 1. Then, based on the sum of the detection pressure corresponding to the second flexible bladder 7 and the target pressure corresponding to the first flexible bladder 1, the pelvic floor pressure is determined. Therefore, the deformation of the first flexible bladder 1 can be prevented from affecting the pelvic floor pressure detection of the second flexible bladder 7, further ensuring the accuracy of the pelvic floor pressure detection.

[0107] It is worth noting that during pelvic floor pressure testing, the pressure is measured by the second flexible bladder 7. Since the second flexible bladder 7 contains a fixed amount of pre-set fluid, its internal volume is considered fixed, and therefore, it is unaffected by volume-related errors. The lower first flexible bladder 1, being essentially the same as the upper second flexible bladder 7, deforms under pressure. This deformation can lead to inaccurate pressure measurements based on the second flexible bladder 7. Therefore, a pressure compensation method can be used to calculate the target pressure inside the first flexible bladder 1. Adding the compensated target pressure to the corresponding detection pressure of the second flexible bladder 7 accurately determines the pelvic floor pressure.

[0108] Understandably, if the first and second fluids are gases, the process of detecting pelvic floor pressure using the first flexible bladder 1 and the second flexible bladder 7 is as follows: The first flexible bladder 1 and the second flexible bladder 7 are placed stacked vertically, with the first flexible bladder 1 below and the second flexible bladder 7 above. The height of the bladder can be controlled by adjusting the volume of the first flexible bladder 1. Upon startup, the second flexible bladder 7 is activated first, and the volume of the second fluid inside the second flexible bladder 7 is adjusted according to the preset fluid volume. When the volume of the second flexible bladder 7 reaches the specified volume (i.e., the preset fluid volume), the first flexible bladder 1 is activated, raising the height of the second flexible bladder 7. Upon contact with the target, the air pressure inside the first flexible bladder 1 begins to rise. When it reaches the pressure threshold, the first pressure regulating component 3 stops adjusting the flow rate of the first fluid inside the first flexible bladder 1. At this point, the pressure intensity inside the first flexible bladder is recorded, along with the adjustment time t. Based on the adjustment time t and the adjustment rate (i.e., the flow rate of the first fluid output by the first drive pump in the first pressure regulating component 3 per unit time), the flow rate of the first fluid inside the first flexible bladder 1 is calculated. Measurement is then taken. Because the first flexible bladder 1 and the second flexible bladder 7, placed vertically, deform when the target exerts force, the flow rate of the second fluid in the second flexible bladder 7 is fixed and does not require compensation; the calibration result can be directly used for output. However, the flow rate of the first fluid in the first flexible bladder 1 is not fixed and requires consulting a pressure compensation table to compensate for the result. Finally, the pelvic floor pressure is obtained by summing the pressure changes of the second flexible bladder 7 and the first flexible bladder 1.

[0109] It should be noted that if the first fluid is a liquid and the second fluid is a gas, the liquid has greater rigidity and less deformation, which does not affect the measurement of the second flexible capsule 7. Therefore, the first flexible capsule 1 only serves to control the height of the second flexible capsule 7, and a pressure compensation scheme is not required.

[0110] For example, see Figure 7 This is a schematic diagram of another controller for detecting pelvic floor pressure provided in an embodiment of the present invention. The specific process is as follows:

[0111] Step S21: After activating the pelvic floor pressure detection, drive the second pressure regulating component 8 to adjust the flow rate of the second fluid in the second flexible bladder 7.

[0112] Step S22: Determine whether the amount of the second fluid in the second flexible capsule 7 has reached the preset amount of fluid. If yes, proceed to step S23. Otherwise, return to step S21 and continue to drive the second pressure regulating component 8 to adjust the amount of the second fluid in the second flexible capsule 7.

[0113] Step S23: Control the second voltage regulating component 8 to shut down.

[0114] Specifically, the adjustment time of the second fluid can be fixed to ensure that the fluid volume of the second fluid is fixed. After the target time is reached, the second pressure regulating component 8 stops working.

[0115] Step S24: Drive the first pressure regulating component 3 to adjust the flow rate of the first fluid in the first flexible bladder 1, increase the pressure in the first flexible bladder 1, and cause the height of the first flexible bladder 1 to change.

[0116] Step S25: The pressure inside the first flexible bladder 1 is detected by the first pressure detection device 2. It is determined whether the pressure inside the first flexible bladder 1 has reached the pressure threshold. If so, step S26 is executed. Otherwise, step S24 is executed, and the first pressure regulating component 3 is driven to continue to adjust the flow rate of the first fluid inside the first flexible bladder 1.

[0117] Step S26: Control the first voltage regulating component 3 to shut down.

[0118] Step S27: Calculate the adjustment time of the first fluid volume in the first flexible capsule 1, and calculate the fluid volume of the first fluid based on the adjustment time and adjustment rate.

[0119] Specifically, based on the adjustment time t and the first fluid output Vcm of the first pressure regulating component 3 per unit time... 3 / s (i.e., adjustment rate) can be used to calculate the fluid volume of the first fluid and the actual fluid volume in the first flexible capsule 1.

[0120] Step S28: Collect the pressure detected by the first pressure detection device 2 and the second pressure detection device 9 to record the pressure change values ​​inside the first flexible bladder 1 and the second flexible bladder 7 in real time.

[0121] Step S29: Based on the detection pressure of the first pressure detection device 2 and the fluid volume of the first fluid, the pressure compensation table is consulted to correct the detection pressure of the first pressure detection device 2 and obtain the target pressure; based on the sum of the detection pressure of the second pressure detection device 9 and the target pressure, the pelvic floor pressure is determined.
