Description

Technical Field

[0001] The present invention relates to the technical field of pressure detection, and in particular to a pelvic floor pressure detection device. Background Art

[0002] In conventional in vitro pelvic floor pressure detection devices, a single bladder is mainly used as the main detection bladder. The bladder is filled with fluid and connected to a pressure sensor and a driving pump that adjusts the amount of fluid in the bladder through a pipeline. When the human body touches the bladder, the muscle contraction of the human body will push the bladder to deform, so that the fluid in the bladder transmits the pressure to the pressure sensor through the pipeline to realize the pelvic floor pressure detection function. However, this method of using a bladder to detect pelvic floor pressure has the problem of inaccurate pelvic floor pressure detection. Summary of the invention

[0003] In view of this, the present invention provides a pelvic floor pressure detection device to solve the problem of inaccurate pelvic floor pressure detection.

[0004] In a first aspect, the present invention provides a pelvic floor pressure detection device, the device comprising a first flexible bladder, a first pressure detection device, a first pressure regulating assembly and a controller:

[0005] The first pressure detection device and the first pressure regulating assembly are respectively connected to the first flexible sac, the first pressure detection device is used to detect the pressure in the first flexible sac, and the first pressure regulating assembly is used to adjust the fluid volume of the first fluid in the first flexible sac to adjust the pressure in the first flexible sac;

[0006] The controller is connected to the first pressure detection device and the first pressure regulating assembly respectively, and during the detection process, the controller is used to control the first pressure regulating assembly to adjust the fluid volume of the first fluid in the first flexible bladder until a preset stop condition is met;

[0007] During the detection process, the controller is used to obtain the fluid volume of the first fluid in the first flexible bladder;

[0008] During the detection process, the controller is further used to obtain 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.

[0009] In this manner, the amount of fluid in the first flexible bladder is adjusted by the first pressure regulating component to adjust the pressure in the first flexible bladder, so that the first flexible bladder is in good contact with the detection object. At the same time, during the detection process, the controller compensates the detection pressure of the first pressure detection device according to the amount of the first fluid in the first flexible bladder to determine the pelvic floor pressure. Therefore, the problem of deviation in the detection pressure caused by different amounts of fluid in the first flexible bladder can be avoided to improve the accuracy of pelvic floor pressure detection.

[0010] In an optional embodiment, the controller is used to control the first pressure regulating assembly to adjust the fluid volume of the first fluid in the first flexible bladder until a preset stop condition is met, including:

[0011] The controller is used to control the first pressure regulating assembly to adjust the fluid volume of the first fluid in the first flexible bladder, and obtain the detection result of the first pressure detection device;

[0012] If the detection result is that the pressure in the first flexible bladder 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 in the first flexible bladder.

[0013] In this manner, when the pressure in the first flexible bladder reaches a pressure threshold, the controller controls the first pressure regulating component to stop adjusting the amount of the first fluid in the first flexible bladder. Therefore, while making the first flexible bladder in as good contact with the human body as possible, large detection errors caused by the excessive volume of the first flexible bladder can be avoided.

[0014] In an optional embodiment, the controller is used to obtain the amount of the first fluid in the first flexible bladder, including:

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

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

[0017] In this manner, the controller counts the adjustment time of the fluid volume of the first fluid in the first flexible bladder, and thus can accurately calculate the fluid volume of the first fluid in the first flexible bladder according to the adjustment time and the adjustment rate.

[0018] In an optional embodiment, the device further includes a flow meter, which is disposed between the first pressure regulating assembly and the first flexible bladder, and is connected to the controller, and the controller is used to obtain a fluid volume of the first fluid based on the flow meter.

[0019] In this manner, a flow meter is provided between the first pressure regulating assembly and the first flexible bladder, so that the amount of the first fluid in the first flexible bladder can be quickly and accurately obtained.

[0020] In an optional embodiment, the device further includes a cushioning component, the cushioning component includes a cushioning piece of at least one height, the cushioning piece is used to be arranged on a first side of the first flexible capsule, and the second side of the first flexible capsule is used to approach the detection object.

[0021] In this manner, a cushioning member of at least one height is provided on the first side of the first flexible bladder away from the detection object. Therefore, during the detection process, the first flexible bladder can be cushioned to ensure good contact between the first flexible bladder and the detection object, and reduce the difference in the amount of fluid in the first flexible bladder to ensure the accuracy of pelvic floor pressure detection.

[0022] In an optional implementation, the controller is used to obtain 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 indicate actual pressures 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 indicate the actual pressures corresponding to different fluid amounts in the first flexible bladder under the same detection pressure, so that the controller can obtain the pelvic floor pressure from the pressure compensation table based on the detection pressure of the first pressure detection device and the fluid amount of the first fluid. Therefore, the detection error caused by different fluid amounts under the same detection pressure can be avoided to ensure the accuracy of the pelvic floor pressure detection. At the same time, the final pelvic floor pressure is determined by looking up the table, which can also improve the correction efficiency of the pelvic floor pressure to a certain extent.

[0025] In an optional embodiment, the device also includes a second flexible capsule, the first side of the second flexible capsule is used to approach the detection object, the second side of the second flexible capsule is used to approach the first side of the first flexible capsule, and the second flexible capsule is used to accommodate a preset amount of second fluid.

[0026] In this method, a second flexible bladder is arranged on a first side of the first flexible bladder close to the detection object, so that the first flexible bladder can control the height of the second flexible bladder to make the second flexible bladder in good contact with the detection object. At the same time, the second flexible bladder is used to contain a preset amount of the second fluid, which can make the internal volume of the second flexible bladder fixed, so as to avoid detection errors caused by different volumes, thereby ensuring the accuracy of pelvic floor pressure detection.

[0027] In an optional embodiment, the material hardness of the second flexible bladder is smaller than the material hardness of the first flexible bladder.

[0028] In this manner, the material hardness of the second flexible bladder close to the detection object is less than that of the first flexible bladder, so that the second flexible bladder can be in full contact with the detection object to ensure the sensitivity of pressure detection. At the same time, the first flexible bladder used for padding during detection can be kept stable.

[0029] In an optional embodiment, the first fluid is different from the second fluid.

[0030] In this manner, the first fluid in the first flexible bladder is different from the second fluid in the second flexible bladder. Therefore, when the pelvic floor pressure is detected, the interference of the first flexible bladder on the second flexible bladder can be reduced.

[0031] In an optional embodiment, the first fluid is liquid, and the second fluid is gas.

[0032] In this method, since liquid is more rigid and deforms less, while gas is more elastic and easily deformed, the first fluid in the first flexible capsule is liquid and the second fluid in the second flexible capsule is gas. This can ensure detection accuracy while avoiding interference of the deformation of the first flexible capsule with the detection of the second flexible capsule.

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

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

[0035] In this manner, a second pressure regulating assembly and a second pressure detecting device are provided in the pelvic floor pressure detecting device, so that the amount of the second fluid in the second flexible bladder can be accurately adjusted by the second pressure regulating assembly, so that the volume of the second flexible bladder is adjusted to a fixed volume, thereby reducing the detection error of the pelvic floor pressure. The pressure in the second flexible bladder is accurately detected by the second pressure detecting device, so as to accurately determine the pelvic floor pressure.

[0036] In an optional embodiment, the controller is further used to obtain 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, and the pressure compensation table is used to indicate the actual pressures 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 bladder and the target pressure corresponding to the first flexible bladder.

[0039] In this manner, the controller queries 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 of the first flexible bladder, and then determines the pelvic floor pressure based on the sum of the detection pressure corresponding to the second flexible bladder and the target pressure corresponding to the first flexible bladder. Therefore, it is possible to avoid the deformation of the first flexible bladder from affecting the pelvic floor pressure detection of the second flexible bladder, so as to further ensure the accuracy of the pelvic floor pressure detection.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0050] At present, the pelvic floor pressure detection device used for in vitro detection of pelvic floor pressure is mainly used in combination with a pulse magnetic stimulation device. Among them, the principle of the pulse magnetic stimulation device is to use a high-voltage alternating current to pass through a coil to generate an induced magnetic field. In the alternating magnetic field, human neuron cells will generate an induced current, causing the neuron cells to depolarize and form neural excitement. Nerve excitement will produce a series of physiological reactions, and the pelvic floor muscles are trained through this mechanism. The application of the pulse magnetic stimulation device in the pelvic floor is consistent with the purpose of the electrical principle therapeutic device. By stimulating the pelvic floor muscle nerves, the pelvic floor muscles are exercised. And because the principle of the pulse magnetic stimulation device is to use a magnetic field for treatment, there is no need to use intracavitary electrodes, and the user does not need to remove his pants, which is convenient to use.

[0051] However, in conventional pelvic floor applications, pelvic floor pressure is mainly detected through an intracavitary sac. The main advantage of the pulse magnetic stimulation device is that it does not require the removal of pants and does not use intracavitary electrodes. Therefore, an external pelvic floor pressure detection device is required to be used in conjunction with the pulse magnetic stimulation device to improve comfort and convenience. Based on this, in the relevant in vitro pelvic floor pressure detection, a single sac is mainly used as the main detection sac. The sac is filled with fluid, and the sac is connected to the pressure sensor and the driving pump for adjusting the amount of fluid by a pipe. When the human body touches the sac, the muscle contraction of the human body will push the sac to deform, so that the fluid in the sac transmits the pressure to the pressure sensor through the pipe to realize the pelvic floor pressure detection function. Specifically, the pelvic floor pressure detection sac is composed of a pressure sensing sac and a support frame installed in the pressure sac. The support frame is used to support the pressure sac. The pressure sensing sac is inflated and raised to contact the detection object to adapt to different detection objects.

[0052] However, since different volumes of gas will experience different internal pressure increases when subjected to the same deformation, if the altitude is forced to continue to rise to accommodate the test object, the bladder will need to be filled with a larger volume of gas, and the tested pressure intensity value will decrease as the volume inside the flexible bladder increases, resulting in inaccurate pelvic floor pressure detection.

[0053] In addition, due to the large differences in human body structure, the height of the perineum in a sitting position is different. If the sac needs to test the pressure value well, it needs to be as close to the perineum as possible. Therefore, in conventional technology, the height of the sac is controlled by the inflation volume or inflation pressure to make the sac in good contact with the perineum or anus of the test subject, so as to effectively collect the deformation of the pelvic floor caused by muscle contraction, to ensure the sensitivity of pressure detection, and to achieve better pelvic floor pressure detection. However, due to the limited inflation height of the sac, it is often unable to adapt well to patients with a higher perineum, resulting in insufficient sensing strength of the sac, which can also cause inaccurate pelvic floor pressure measurement.

[0054] In view of this, according to an embodiment of the present invention, a pelvic floor pressure detection device is provided. Figure 1: 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 by the embodiment of the present invention includes a first flexible sac 1, a first pressure detection device 2, a first pressure regulating component 3 and a controller 4; wherein the first pressure detection device 2 and the first pressure regulating component 3 are respectively connected to the first flexible sac 1, the first pressure detection device 2 is used to detect the pressure in the first flexible sac 1, and the first pressure regulating component 3 is used to adjust the fluid volume of the first fluid in the first flexible sac 1 to adjust the pressure in the first flexible sac 1; the controller 4 is respectively connected to the first pressure detection device 2 and the first pressure regulating component 3, and during the detection process, 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 sac 1 until a preset stop condition is met; during the detection process, the controller 4 is used to obtain the fluid volume of the first fluid in the first flexible sac 1; during the detection process, the controller 4 is also used to obtain 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.

[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 is used to sense the deformation of the pelvic floor muscles of the detection object and deform. The fluid inside the first flexible bladder 1 produces pressure changes due to the deformation, and the pressure is transmitted to the first pressure detection device 2 through the first connecting pipe 5, thereby realizing the collection of pelvic floor muscle pressure signals, and then the controller 4 performs data collection and processing to control the first pressure regulating component 3 and output the pelvic floor pressure.

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

[0057] The pelvic floor pressure detection device provided in this embodiment adjusts the amount of fluid in the first flexible bladder 1 through the first pressure regulating component 3 to adjust the pressure in the first flexible bladder 1, so that the first flexible bladder 1 is in good contact with the detection object. At the same time, during the detection process, the controller 4 compensates the detection pressure of the first pressure detection device 2 according to the amount of the first fluid in the first flexible bladder 1 to determine the pelvic floor pressure. Therefore, the problem of deviation in the detection pressure caused by different amounts of fluid inside the first flexible bladder 1 can be avoided, so as to improve the accuracy of pelvic floor pressure detection.

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

[0059] It should be noted that the height of the first flexible sac 1 is jointly determined by the first pressure detecting device 2 and the first pressure regulating component 3. The first pressure regulating component 3 continuously pushes the first fluid into the first flexible sac 1. The first flexible sac 1 gradually rises as the amount of the first fluid increases. After the first flexible sac 1 touches the human body, the first flexible sac 1 cannot continue to deform, and the internal pressure of the first flexible sac 1 changes. When the pressure in the first flexible sac 1 reaches the pressure threshold, it means that the first flexible sac 1 is in good contact with the detection object at this time, and the first pressure regulating component 3 stops working. At this time, the first flexible sac 1 reaches a measurable state. The user contracts the pelvic floor muscles through software or guidance, and the first flexible sac 1 produces a pressure change. The pressure value is collected through the first pressure detecting device 2 to obtain the pelvic floor pressure.

[0060] Specifically, the first pressure regulating assembly 3 includes a first driving pump and a first switch valve. The first driving pump is responsible for adjusting the fluid volume of the first fluid in the first flexible sac 1 and the first connecting pipe 5 so that the volume and internal pressure of the first flexible sac 1 change. The first switch valve is responsible for connecting the first flexible sac 1 and the first connecting pipe 5 with the outside. When starting the work, under the control of the controller 4, the first switch valve is closed to make the first flexible sac 1 and the first connecting pipe 5 airtight. When the first driving pump works, it will not cause leakage of the first fluid; when the internal pressure of the first flexible sac 1 exceeds the preset maximum threshold, the first switch valve is opened to release the excess first fluid to ensure that the internal pressure of the first flexible sac 1 reaches the set pressure threshold. After the pelvic floor pressure measurement is completed, the first switch valve is opened to release the internal pressure of the first flexible sac 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 according to the pressure value detected when the first flexible capsule 1 is in good contact with different detection objects, and the pressure threshold is used to characterize the degree of fit between the detection object and the first flexible sensing capsule.

[0062] In the pelvic floor pressure detection device provided in this embodiment, when the pressure in 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 in the first flexible bladder 1. Therefore, while making the first flexible bladder 1 in as good contact with the human body as possible, it is possible to avoid a large detection error 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 in the first flexible sac 1, including: the controller 4 is used to count the adjustment time of the fluid volume of the first fluid in the first flexible sac 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] In the pelvic floor pressure detection device provided in this embodiment, the controller 4 counts the adjustment time of the fluid volume of the first fluid in the first flexible bladder 1, and thus can accurately calculate the fluid volume of the first fluid in the first flexible bladder 1 according to the adjustment time and the adjustment rate.

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

[0066] In the pelvic floor pressure detection device provided in this embodiment, a flow meter is arranged between the first pressure regulating assembly 3 and the first flexible bladder 1 , so that the fluid volume of the first fluid in the first flexible bladder 1 can be quickly and accurately obtained.

[0067] It can be understood that a flow meter is installed on the first connecting pipe 5 between the first flexible sac 1 and the first pressure regulating assembly 3. When the first pressure regulating assembly 3 adjusts the fluid volume of the first fluid in the first flexible sac 1, the fluid will flow through the flow meter, and the fluid volume of the first fluid in the first flexible sac 1 can be directly measured.

[0068] See also Figure 3 As one of the optional embodiments, the pelvic floor pressure detection device also includes a cushioning component 6, the cushioning component 6 includes a cushioning member of at least one height, the cushioning member is used to be arranged on the first side of the first flexible bladder 1, and the second side of the first flexible bladder 1 is used to be close to the detection object.

[0069] The pelvic floor pressure detection device provided in this embodiment is provided with a cushioning member of at least one height on the first side of the first flexible bladder 1 away from the detection object. Therefore, during the detection process, the first flexible bladder 1 can be cushioned to make the first flexible bladder 1 in good contact with the detection object and reduce the difference in the amount of fluid in the first flexible bladder 1 to ensure the accuracy of pelvic floor pressure detection.

[0070] Optionally, the raising member is a raising rubber pad.

[0071] It is worth noting that, in actual use, the cushioning component 6 may include one or more cushioning parts of different heights. The user can replace the cushioning parts according to the approximate height of the perineum / pelvic floor of the detection object, so as to make the first flexible sac 1 in good contact with the detection object, thereby solving the difference in sensitivity of the first flexible sac 1 to the deformation of the pelvic floor muscles caused by the difference in human body size. At the same time, it can reduce the difference in the amount of the first fluid in the first flexible sac 1 for different detection objects, so as to reduce the pelvic floor pressure detection error, thereby improving the accuracy of pelvic floor pressure detection for different perineum / pelvic floor heights of detection objects.

[0072] Furthermore, the controller 4 is used to obtain the detection pressure of the first pressure detection device 2, and compensate the detection pressure based on the fluid volume of the first fluid for determining the pelvic floor pressure, including: the controller 4 is used to query the 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, and the pressure compensation table is used to represent the actual pressures 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 indicate the actual pressures corresponding to different fluid amounts in the first flexible bladder 1 at the same detection pressure, so that the controller 4 obtains the pelvic floor pressure from the pressure compensation table based on the detection pressure of the first pressure detection device 2 and the fluid amount of the first fluid. Therefore, the detection error caused by different fluid amounts at the same detection pressure can be avoided to ensure the accuracy of the pelvic floor pressure detection. At the same time, the final pelvic floor pressure is determined by looking up the table, which can also improve the correction efficiency of the pelvic floor pressure to a certain extent.

[0074] It should be noted that since it is impossible to accurately determine the height applicable to different detection objects, after being raised by the raising component 6, the height of the first flexible sac 1 is difficult to fit the human body exactly, and there is still a small amount of error. Therefore, on the basis of raising by the raising component 6, the fluid volume control of the first fluid can be adopted. Since the first pressure regulating component 3 can be calibrated as a 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 sac 1 by the first pressure regulating component 3, and the pressure measurement error caused by the difference in compensation volume can be calculated by the first fluid volume corresponding to the fluid volume of the first fluid.

[0075] Specifically, the process of detecting the pelvic floor pressure using the cushioning component 6 and a single flexible bladder is as follows: according to the actual height requirements, a cushioning component of a suitable height is preliminarily selected from the cushioning components of multiple heights of the cushioning component 6 for preliminary height control. The first flexible bladder 1 can reduce the fluid volume of the first fluid through the cushioning component. During detection, the controller 4 controls the first pressure regulating component 3 to adjust the fluid volume of the first fluid in the first flexible bladder 1. When it contacts the detection object, the pressure in the first flexible airbag begins to rise. When it rises to the pressure threshold, the first pressure regulating component 3 is stopped, and the adjustment time t is recorded at the same time. The fluid volume of the first fluid in the first flexible bladder 1 is calculated according to the adjustment time t and the adjustment rate of the first pressure regulating component 3. The pressure compensation table is queried by the fluid volume of the first fluid and the detection pressure of the first pressure detection device 2 to correct the currently collected pressure change value and obtain the real pressure data for determining the pelvic floor pressure.

[0076] It should be noted that the data in the pressure compensation table is calibrated by standard weight. Under different fluid volumes, the same external pressure is calibrated to obtain different pressure values. Subsequently, under different external pressure conditions, the pressure values ​​for different fluid volumes are calibrated to form a queryable pressure compensation table as shown below.

[0079] For example, see Figure 4 , is a schematic diagram of a flow chart of a controller detecting pelvic floor pressure provided by an embodiment of the present invention, and the specific flow chart is as follows:

[0080] Step S11 , after starting the pelvic floor pressure detection, driving the first pressure regulating component 3 to adjust the fluid volume of the first fluid in the first flexible bladder 1 .

[0081] Step S12, detect the pressure in the first flexible bladder 1 through the first pressure detection device 2 to determine whether the pressure in the first flexible bladder 1 reaches the pressure threshold. If so, execute step S13; otherwise, return to step S11 to continue driving the first pressure regulating component 3 to adjust the fluid volume of the first fluid in the first flexible bladder 1.

[0082] Step S13, controlling the first voltage regulating component 3 to close.

[0083] It can be understood that when the first flexible bladder 1 contacts the detection object, the internal pressure of the first flexible bladder 1 gradually increases until it reaches the designed pressure threshold, and then the first pressure regulating component 3 stops.

[0084] Step S14, counting the adjustment time of the fluid volume of the first fluid in the first flexible bladder 1, and calculating the fluid volume of the first fluid according to the adjustment time and the adjustment rate.

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

[0086] Step S15 , collecting the detection pressure of the first pressure detection device 2 , and recording the current pressure change value of the first flexible bladder 1 in real time.

[0087] Step S16, querying 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 correct the detection pressure of the first pressure detection device 2, thereby obtaining the pelvic floor pressure.

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

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

[0090] Specifically, Figure 5 As shown, the first flexible capsule 1 and the second flexible capsule 7 are placed overlapping each other, the upper second flexible capsule 7 is the capsule for main detection, and the lower first flexible capsule 1 can control the height of the cushion by controlling the volume.

[0091] It is worth noting that, in this embodiment, in the process of adjusting the fluid volume 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 detection object, thereby reducing the detection error caused by the inadequate contact between the second flexible capsule 7 and the detection object.

[0092] In the pelvic floor pressure detection device provided in this embodiment, the second flexible bladder 7 is arranged on the first side of the first flexible bladder 1 close to the detection object, so that the first flexible bladder 1 can control the height of the second flexible bladder 7 to make the second flexible bladder 7 in good contact with the detection object. At the same time, the second flexible bladder 7 is used to contain a preset amount of the second fluid, which can make the internal volume of the second flexible bladder 7 fixed, so as to avoid detection errors caused by different volumes, thereby ensuring the accuracy of pelvic floor pressure detection.

[0093] As one of the optional implementations, the material hardness of the second flexible capsule 7 is smaller than the material hardness of the first flexible capsule 1 .

[0094] Specifically, the first flexible capsule 1 is made of a relatively hard soft glue, and the second flexible capsule 7 is made of a relatively flexible soft glue.

[0095] In the pelvic floor pressure detection device provided in this embodiment, the material hardness of the second flexible bladder 7 close to the detection object is less than the material hardness of the first flexible bladder 1, so that the second flexible bladder 7 can be fully in contact with the detection object to ensure the sensitivity of pressure detection. At the same time, the first flexible bladder 1 that is raised during detection can be kept stable.

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

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

[0098] The pelvic floor pressure detection device provided in this embodiment has a first fluid in the first flexible bladder being liquid and a second fluid in the second flexible bladder being gas, because the liquid has strong rigidity and less deformation, while the gas has great elasticity and is easy to deform. Therefore, the first fluid in the first flexible bladder is liquid and the second fluid in the second flexible bladder is gas. The device can adapt to the detection height of different detection objects to ensure the detection accuracy while avoiding the deformation of the first flexible bladder 1 from interfering with the detection of the second flexible bladder 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 fluid volume of the second fluid in the second flexible bladder 7 to adjust 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 assembly 8 and the second pressure detecting device 9 are connected to the second flexible bladder 7 through the second connecting pipe 10 respectively.

[0101] Specifically, the second pressure regulating assembly 8 includes a second driving pump and a second switch valve. The second driving pump is responsible for adjusting the amount of the second fluid in the second flexible sac 7 and the second connecting pipe 10 so that the volume and internal pressure of the second flexible sac 7 change. The second switch valve is responsible for connecting the second flexible sac 7 and the second connecting pipe 10 with the outside. When starting the work, under the control of the controller 4, the second switch valve is closed to make the second flexible sac 7 and the second connecting pipe 10 airtight. When the second driving pump is working, the second fluid will not leak. After the pelvic floor pressure measurement is completed, the second switch valve is opened to release the internal pressure of the second flexible sac 7.

[0102] It is worth noting that, in the actual process of adjusting the fluid, the second pressure regulating component 8 can be started first, and the second flexible capsule 7 can be filled with the second fluid according to the preset fluid volume. When the fluid volume of the second fluid in the second flexible capsule 7 reaches the preset fluid volume, the first pressure regulating component 3 is started to fill the first flexible capsule 1 below with the first fluid to increase the height of the second flexible capsule 7. When it contacts the human body, the pressure in the first flexible capsule 1 begins to increase, and when it increases to the pressure threshold, the adjustment of the fluid volume of the first fluid in the first flexible capsule 1 is stopped.

[0103] As an optional embodiment, when adjusting the fluid volume of the second fluid in the second flexible sac 7, the target time for the second flexible sac 7 to reach a preset fluid volume can be determined in advance based on the adjustment rate of the second pressure regulating component 8. If the time for the second pressure regulating component 8 to adjust the fluid volume of the second fluid in the second flexible sac 7 reaches the target time, it indicates that the fluid volume of the second fluid in the second flexible sac 7 reaches the preset fluid volume at this time, and the controller controls the second pressure regulating component 8 to stop adjusting the fluid volume of the second fluid in the second flexible sac 7.

[0104] As an optional embodiment, the pelvic floor pressure detection device is provided with a flow meter between the second pressure regulating assembly 8 and the second flexible bladder 7, and the flow meter is connected to the controller 4. The controller 4 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 obtain the detection pressure of the first pressure detection device 2, and compensate the detection pressure based on the fluid volume of the first fluid for determining the pelvic floor pressure, including: during the detection process, the controller 4 is used to query the 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 sac 1, and the pressure compensation table is used to represent the actual pressures corresponding to different fluid volumes in the first flexible sac 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 sac 7 and the target pressure corresponding to the first flexible sac 1.

[0106] In the pelvic floor pressure detection device provided in this embodiment, the controller 4 queries the 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, and then determines 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. Therefore, it is possible to avoid the deformation of the first flexible bladder 1 from affecting the pelvic floor pressure detection of the second flexible bladder 7, so as to further ensure the accuracy of the pelvic floor pressure detection.

[0107] It is worth noting that, when the pelvic floor pressure is detected, the pressure is measured by the second flexible bladder 7. Since the second flexible bladder 7 contains a fixed preset amount of the second fluid, it is considered that the internal volume of the second flexible bladder 7 is fixed, and the second flexible bladder 7 is not affected by the volume. The first flexible bladder 1 below is basically the same as the second flexible bladder 7 above, and will deform when subjected to pressure. This deformation will cause inaccurate pressure detection based on the second flexible bladder 7. Therefore, the pressure compensation method can be used to calculate the target pressure inside the first flexible bladder 1, and the compensated target pressure can be added to the detection pressure corresponding to the second flexible bladder 7 to accurately determine the pelvic floor pressure.

[0108] It can be understood that if the first fluid and the second fluid are gas, the process of detecting the 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 overlapping each other, with the first flexible bladder 1 at the bottom and the second flexible bladder 7 at the top, and the height of the cushion can be controlled by controlling the volume of the first flexible bladder 1. When starting, the second flexible bladder 7 is started first, and the fluid volume of the second fluid in the second flexible bladder 7 is adjusted according to the preset fluid volume. When the volume of the second flexible bladder 7 reaches the limited volume (that is, the preset fluid volume), the first flexible bladder 1 is started to increase the height of the second flexible bladder 7. After contacting the detection object, the air pressure in the first flexible capsule 1 begins to rise. When it rises to the pressure threshold, the first pressure regulating component 3 stops adjusting the fluid volume of the first fluid in the first flexible capsule 1. At this time, the pressure intensity in the first flexible airbag is recorded, and the adjustment time t is recorded at the same time. According to the adjustment time t and the adjustment rate (i.e., the fluid volume of the first fluid output by the first driving pump in the first pressure regulating component 3 per unit time), the fluid volume of the first fluid in the first flexible capsule 1 is calculated. At this time, when the detection object exerts force, the first flexible capsule 1 and the second flexible capsule 7 placed up and down will both produce deformation. Since the fluid volume of the second fluid in the second flexible capsule 7 is fixed, no compensation is required, and the calibration result can be directly used for output. However, the fluid volume of the first fluid in the first flexible capsule 1 is not fixed, and the pressure compensation table needs to be queried to compensate the result. Finally, the pelvic floor pressure is obtained according to the sum of the pressure change results of the second flexible capsule 7 and the first flexible capsule 1.

[0109] It should be noted that if the first fluid is liquid and the second fluid is gas, the liquid has stronger rigidity and less deformation, and does not affect the measurement of the second flexible capsule 7. Therefore, the first flexible capsule 1 only plays the role of controlling the height of the second flexible capsule 7, and the pressure compensation solution does not need to be adopted.

[0110] For example, see Figure 7 , is a schematic diagram of a flow chart of another controller detecting pelvic floor pressure provided by an embodiment of the present invention, and the specific flow chart is as follows:

[0111] Step S21 , after starting the pelvic floor pressure detection, driving the second pressure regulating assembly 8 to adjust the fluid volume of the second fluid in the second flexible bladder 7 .

[0112] Step S22 , determining whether the amount of the second fluid in the second flexible bladder 7 reaches a preset amount of fluid, if yes, executing step S23 , if no, returning to step S21 to continue driving the second pressure regulating assembly 8 to adjust the amount of the second fluid in the second flexible bladder 7 .

[0113] Step S23, controlling the second voltage regulating component 8 to close.

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

[0115] Step S24 , driving the first pressure regulating assembly 3 to adjust the amount of the first fluid in the first flexible bladder 1 , increasing the pressure in the first flexible bladder 1 , so that the height of the first flexible bladder 1 changes.

[0116] Step S25, detect the pressure in the first flexible bladder 1 through the first pressure detection device 2, and determine whether the pressure in the first flexible bladder 1 reaches the pressure threshold. If so, execute step S26; otherwise, return to execute step S24 and drive the first pressure regulating component 3 to continue to adjust the fluid volume of the first fluid in the first flexible bladder 1.

[0117] Step S26, controlling the first voltage regulating component 3 to close.

[0118] Step S27 , counting the adjustment time of the fluid volume of the first fluid in the first flexible bladder 1 , and calculating the fluid volume of the first fluid according to the adjustment time and the adjustment rate.

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

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

[0121] Step S29, query the pressure compensation table according to the detection pressure of the first pressure detection device 2 and the fluid volume of the first fluid to correct the detection pressure of the first pressure detection device 2 to obtain the target pressure; determine the pelvic floor pressure based on the sum of the detection pressure of the second pressure detection device 9 and the target pressure.
