Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, more particularly to a device and method for pelvic floor pressure detection and height adjustment. BACKGROUND

[0002] Female pelvic floor dysfunction (PFD) includes a series of diseases such as pelvic organ prolapse, urinary incontinence, pelvic pain, and sexual dysfunction, which is a common disease among middle-aged and elderly women with an incidence of 30%-40%, seriously affecting the health and quality of life of women. The conventional external pelvic floor pressure detection device is used by placing the air bag under the pelvic floor muscle, connecting the air bag with the pressure regulating module and the pressure sensor, squeezing the air bag below when the pelvic floor muscle contracts, and then detecting the air bag pressure change through the pressure sensor to realize the pelvic floor muscle pressure detection. However, due to reasons such as body type, it is not possible to ensure that the pelvic floor muscle of each patient is in close contact with the pressure air bag, which may cause inaccurate detection. The patent for invention with publication number CN119587028A discloses a pelvic floor pressure detection device, which controls the height of the second flexible bladder body through the first flexible bladder body, and realizes good contact between the second flexible bladder body and the detection object. However, the invention separates the pressure regulation and pressure detection device of the first flexible bladder body and the second flexible bladder body, increases the cost of the equipment, cannot realize the free adjustment of multiple different heights, has a small range of adaptation to the population, and has inaccurate pressure detection. SUMMARY

[0003] The existing pelvic floor pressure detection device has low adjustment accuracy, a small range of adaptation to the population, and inaccurate pressure detection. In order to overcome this defect, the present application provides a device and method for pelvic floor pressure detection and height adjustment, which has a larger adjustment range, higher adjustment accuracy, a larger range of adaptation to the population, and more accurate pressure detection.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: A device for pelvic floor pressure detection and height adjustment, comprising a detection air bag and a height-increasing air bag, wherein the detection air bag is provided with an air bag pressure sensor, the detection air bag and the height-increasing air bag are both in communication with an air pump, and the air bag pressure sensor and the air pump are both electrically connected with a control module. The control module receives the pressure signals of the air bag pressure sensor and the atmospheric pressure sensor, controls the working state of the air pump, controls the pressure of the detection air bag and adjusts the height of the air bag, and detects the pressure of the pelvic floor muscle acting on the air bag. Under the unified control of the control module, the device for pelvic floor pressure detection and height adjustment can flexibly adjust the height and pressure of the air bag according to the needs of patients with different body types and different physical conditions, greatly increasing the range of adaptation to the population.

[0005] Preferably, the detection air bag and the heightening air bag are both bellows type. The bellows type air bag has only one dimension of expansion and contraction freedom, and is relatively regular in shape. When not in use, the bellows type air bag can be folded to save space, facilitating storage and transportation of the device.

[0006] Preferably, the heightening air bag is multiple and arranged in sequence along the expansion and contraction direction to form a heightening air bag group, and the heightening air bag group is attached to one side of the detection air bag. The combination of multiple heightening air bags can provide a wider range of height selection to meet the needs of different patients for the height of the detection air bag, and can achieve more precise height adjustment, further improving the ability of the device to adapt to different populations.

[0007] Preferably, the device for pelvic floor pressure detection and height adjustment further comprises an atmospheric pressure sensor and a temperature sensor, both of which are electrically connected to the control module. The atmospheric pressure sensor is used to detect atmospheric pressure and calibrate the pressure of the detection air bag. The temperature sensor is used to detect the ambient temperature and calibrate the pressure of the detection air bag. In medical institutions in different regions, the local atmospheric pressure and temperature differ greatly. By detecting the local atmospheric pressure and temperature and calculating the target pressure inside the detection air bag according to a preset relationship, the influence of pressure changes caused by regional environmental differences on detection accuracy can be effectively avoided, ensuring that the pressure of the detection air bag accurately reflects the pelvic floor muscle pressure regardless of where the patient comes from, and improving the accuracy and reliability of the detection.

[0008] Preferably, the device for pelvic floor pressure detection and height adjustment further comprises an audio-visual feedback module, which is electrically connected to the control module. The audio-visual feedback module can give the patient appropriate prompts according to the active movement score calculated by the control module. When the score exceeds the preset score and the magnetic stimulation is started, and when the score is lower than the preset score and the patient is prompted to contract, the audio-visual feedback module promptly informs the patient of the training status through sound, light, character prompts, etc., helping the patient better understand their training situation and adjust the training method and intensity, thereby improving the training effect. In community hospitals and rehabilitation centers, patients generally reflect that the audio-visual feedback module makes the training process more intuitive, which helps to improve the enthusiasm and initiative of training.

[0009] A method for active training of pelvic floor magnetic stimulation, comprising the following steps: S1. Turn on the device, start the air pump through the control module, and empty the heightening air bag; S2. Detect the atmospheric pressure and temperature at the location of the device, calculate the target pressure inside the detection air bag according to the detection results, start the air pump to pressurize, and continue until the pressure inside the detection air bag reaches the preset value; S3. The patient sits above the detection airbag, and the detection airbag and the heightening airbag are pressurized until the pelvic floor muscles and the detection airbag are in sufficient contact; S4. The patient performs an assessment and training of the pelvic floor muscle contraction; S5. The training is completed, and the control module controls the air pump to empty the heightening airbag for use by the next patient.

[0010] The method clearly defines a series of processes from emptying the heightening airbag when the device is turned on to determining the target pressure according to the detection environment parameters, adjusting the airbag height when the patient sits, performing the training, and emptying the heightening airbag when the training is completed, so that the entire training process is standardized. When applied in different medical institutions, medical staff and patients can clearly understand the operation steps, facilitating the promotion and use of the device, and also ensuring the consistency and stability of the training effect.

[0011] As a preferred, the target pressure P0 inside the detection airbag and the atmospheric pressure P T satisfy the relationship: P0=a k* a P* a T* P T , where a k is a fixed multiple, a P is a gas pressure correlation coefficient, and a T is a gas temperature correlation coefficient. By detecting the atmospheric pressure and temperature at the location of the device and calculating the target pressure inside the detection airbag according to the clear relationship, the influence of environmental factors on the airbag pressure is fully considered, and the target pressure inside the detection airbag suitable for the patient can be accurately determined. In different seasons and different regions, accurate target pressure can be calculated according to actual environmental parameters, providing protection for subsequent accurate detection of pelvic floor muscle pressure and improving the accuracy and reliability of detection.

[0012] As an alternative, the target pressure P0 inside the detection airbag and the standard atmospheric pressure difference P δ form a linear function relationship, satisfying the relationship: P0=P a +kP δ , where P a is the atmospheric pressure, and k is the gas pressure correlation coefficient. By detecting the atmospheric pressure at the location of the device and calculating the target pressure inside the detection airbag according to the clear relationship, the influence of environmental factors on the airbag pressure is fully considered, and the target pressure inside the detection airbag suitable for the patient can be accurately determined. In different seasons and different regions, accurate target pressure can be calculated according to actual environmental parameters, providing protection for subsequent accurate detection of pelvic floor muscle pressure and improving the accuracy and reliability of detection.

[0013] As preferred, the control program of the control module has an optimal pelvic floor contraction model and an active control model, during active training, the pelvic floor muscle and compensatory site signals are collected and substituted into the active control model together with the optimal pelvic floor contraction model, and the active movement score of the training object is calculated; when the score exceeds the preset score, the magnetic stimulation is started; when the score is lower than the preset score, the patient is prompted to make efforts to contract. The active movement score mechanism provides an objective evaluation standard for the training effect. Medical staff can understand the training progress of the patient according to the score, and timely adjust the training scheme; the patient can also intuitively see the training results through the score, and enhance the training confidence and enthusiasm. This objective evaluation method helps to improve the training compliance of the patient, and further improves the overall training effect.

[0014] As preferred, the pressure change of the detection air bag before and after sitting is compared, when the pressure value is lower than the preset minimum threshold value, it is determined that the pelvic floor muscle and the detection air bag are not in sufficient contact, and the detection air bag height needs to be increased; when the pressure value is greater than or equal to the preset minimum threshold value and less than or equal to the preset maximum threshold value, it is considered that the pelvic floor muscle and the detection air bag are in good contact; when the pressure value is greater than or equal to the preset maximum threshold value, the detection air bag height is reduced. This mechanism of automatically adjusting the air bag height according to the pressure change does not require manual operation of the patient, improves the convenience and comfort of use, and optimizes the user experience. The patient only needs to sit on the detection air bag according to the indication, and the device can automatically adjust to the appropriate state, reducing the patient's distress during use, so that the patient can focus more on pelvic floor muscle training, which helps to improve the training effect.

[0015] The beneficial effects of the present application are: More accurate evaluation of training effect. In the present application, the optimal target pressure is determined by collecting atmospheric pressure and temperature before training after the device is started, which can avoid the influence of pressure change caused by different altitudes in different cities on detection accuracy; after the target pressure is determined, whether the patient's pelvic floor muscle is in good contact with the air bag is determined by comparing with the experience threshold value according to the air bag pressure change after the patient sits, and the sufficient contact with the patient is ensured by increasing or reducing the air bag height; at the same time, the accuracy of the result is ensured by correcting the collected pressure value.

The control module 5 is a computer host that can control the corresponding equipment operating system. Data processing includes preprocessing such as notch filtering and bandpass filtering at power frequency, acquiring the preprocessed data, and then calculating characteristic values, including: mean, standard deviation, and so on.

[0024] The audio-visual feedback module 9 is a display, wherein the visual feedback forms include the change curve of the pelvic floor pressure, the broken line chart, etc., and can also be the movement of the pelvic floor muscle presented by using the virtual reality technology; the audio feedback forms include the voice guidance provided by the system, the prompt of starting and stopping, the feedback of success or failure, etc. The detection air bag 2 and the height increasing air bag 3 are both the bellows type telescopic folding structures, which can only expand and contract in one dimension, that is, the length between the front and rear ends of the detection air bag 2 and the height increasing air bag 3 is fixed, and the length between the top and bottom sides is variable. The height increasing air bag 3 is three, and the three height increasing air bags 3 are sequentially arranged and connected along the telescopic direction to form a height increasing air bag group, which is attached to the bottom side of the detection air bag 2. The middle segment of the surface of the top side of the detection air bag 2 is a cylindrical surface, and the two sides are hemispherical surfaces, so that the top side of the detection air bag 2 directly contacting with the human body is relatively smooth, the edges and corners are eliminated, and the discomfort when contacting with the human body is avoided.

[0038] In S2, the atmospheric pressure fluctuates due to factors such as season and temperature, and P δ represents the standard atmospheric pressure difference value. The target pressure inside the detection airbag 2 is the sum of the atmospheric pressure and the fixed pressure difference value, which is corrected by the air pressure correlation coefficient, and specifically satisfies the relationship: P0=P a +kP δ , wherein P a is the atmospheric pressure, and k is the air pressure correlation coefficient. In S3, the pressure change of the detection airbag 2 before and after sitting is compared to determine whether the pelvic floor muscles and the detection airbag 2 are in sufficient contact. When the pressure value is lower than the preset minimum threshold value, it is determined that the pelvic floor muscles and the detection airbag 2 are not in sufficient contact, and the height of the detection airbag 2 needs to be increased; when the pressure value is greater than or equal to the preset minimum threshold value and less than or equal to the preset maximum threshold value, it is considered that the pelvic floor muscles and the detection airbag 2 are in good contact; when the pressure value is greater than the preset maximum threshold value, it is determined that the detection airbag 2 is too high in position, and the height of the detection airbag 2 needs to be reduced.

[0039] When the patient sits, the threshold value of the pressure change is: T min =P0+K W1 *K H1 *P0, T max =P0+K W2 *K H2 *P0 , wherein T min is the preset minimum pressure threshold value, T max is the preset maximum pressure threshold value, K W1 is the user weight correlation coefficient of the minimum pressure threshold value, K W2 is the user weight correlation coefficient of the maximum pressure threshold value, K H1 is the user height correlation coefficient of the minimum pressure threshold value, and K H1 is the user height correlation coefficient of the maximum pressure threshold value. The calculation formula of the pressure threshold value and the correlation coefficient are pre-stored in the control module 5, and the corresponding threshold value is automatically calculated according to the working environment and state of the device. The control program of the control module 5 has an optimal pelvic floor contraction model and an active control model. In active training, the pelvic floor muscle and compensatory site signals are collected and substituted into the active control model together with the optimal pelvic floor contraction model to calculate the active movement score of the training object; when the score exceeds the preset score, the magnetic stimulation is started; when the score is lower than the preset score, the patient is prompted to make efforts to contract.

[0040] When the airbag 3 needs to be inflated, the airbag 3 and the detection airbag 2 to be inflated are connected to the air pump 4 through the switch electromagnetic valve 8 to be inflated until the target pressure is reached. When the airbag height needs to be higher, the above operation is repeated. When the airbag 3 is started, the volume in the airbag increases, and the pressure value needs to be corrected. Then the corrected front and rear pressure difference ΔP is: ΔP = K T *K F (P1-P0)*(V0+n*V1) / V0 Wherein K T is the correction coefficient of real-time temperature, K F is the correction coefficient of real-time atmospheric pressure, V0 is the volume when the detection airbag target air pressure, V1 is the volume of a single airbag target air pressure, P0 is the target pressure, P1 is the airbag pressure after the patient sits down, n is the number of airbags, and n=4 in this embodiment. The correction formula and related coefficients are pre-stored in the control module 5, and the corresponding correction is automatically calculated according to the working environment and state of the device.
