Description

Technical Field

[0001] The invention relates to rehabilitation equipment, in particular to a pelvic floor muscle repairing device. Background Art

[0002] After childbirth, the pelvic floor muscles and their fascia lose elasticity due to expansion, and some muscle fibers often rupture. If you can persist in rehabilitation exercises after childbirth, the pelvic floor muscles can recover to a state close to that before pregnancy, thereby reducing the occurrence of pelvic floor dysfunction diseases such as pelvic organ prolapse and urinary incontinence.

[0003] The existing pelvic floor muscle contraction rehabilitation training device has simple functions. Usually, the user's legs perform simple linear motion or opening and closing motion on the existing device to drive the movement of the pelvic floor muscles. Although this exercise method can exercise the pelvic muscles, the effect is poor and the rehabilitation effect is slow, which is difficult to meet the needs of postpartum women for rapid recovery.

[0004] Kegel exercise is an effective method for repairing pelvic floor muscles. However, Kegel exercises often involve pressing the vaginal wall with fingers, pinching off urine, and lifting the anus. Conventional Kegel exercises require users to use mirrors and other methods to help trainers find the position of the pelvic floor muscles, and require trainers to concentrate on mobilizing local muscles for training. It is inconvenient to use and has a certain threshold. It is difficult for users to guarantee the effect of Kegel exercises by themselves. Summary of the invention

[0005] The main technical problem to be solved by the present invention is to provide a pelvic floor muscle repairing instrument with bidirectional feedback to solve the problem that users do not know how to perform Kegel exercises correctly.

[0006] In order to solve the above technical problems, the present invention provides a pelvic floor muscle repair instrument, comprising a base and an airbag placed on the base, and also comprising a main control module and a pressure sensor, wherein the airbag is connected to the pressure sensor, and the pressure sensor is used to detect the pressure of the airbag and send it to the main control module;

[0007] The main control module is configured to determine whether the user has completed the upward contraction of the pelvic floor muscles according to the value fed back by the pressure sensor, including the following steps:

[0008] Step 1: After the airbag starts to inflate for N seconds, determine whether the pressure value detected by the pressure sensor increases. If so, determine that the user has correctly contracted the pelvic floor muscles, and go to step 3. Otherwise, determine that the user has not correctly contracted the pelvic floor muscles, and go to step 2.

[0009] Step 2: stop recording the pressure value of the pressure sensor, feed back a signal indicating that the pressure value remains unchanged to the user, and return to step 1;

[0010] Step 3: Record the pressure value of the pressure sensor, feed back a signal of the pressure value change to the user, and return to step 1.

[0011] In a preferred embodiment: Step 2 also includes: determining that the user has not correctly contracted the pelvic floor muscles, controlling the airbag to maintain the current inflation state, or controlling the air pressure of the airbag to gradually increase to force the user to correctly contract the pelvic floor muscles.

[0012] In a preferred embodiment: in step 2, a signal that the pressure value remains unchanged is fed back to the user, or,

[0013] In step 3, a signal of the pressure value change is fed back to the user, wherein the feedback form includes at least one of a pressure-time curve graph, a pressure-time bar graph, a pressure-time data table, a prompt light and a prompt sound.

[0014] In a preferred embodiment: it also includes a vibration motor, and step 2 also includes: determining that the user has not correctly contracted the pelvic floor muscles, controlling the vibration motor to vibrate to provide feedback to the user; the vibration amplitude or frequency of the vibration motor is negatively correlated with the pressure value detected by the pressure sensor.

[0015] In a preferred embodiment: in the step 1, it is determined whether the pressure value detected by the pressure sensor increases. If so, it is determined that the user has correctly contracted the pelvic floor muscles. Specifically, it is determined whether the pressure value detected by the pressure sensor increases and whether the pressure value exceeds a reference value. If so, it is determined that the user has correctly contracted the pelvic floor muscles. Otherwise, it is determined that the user has not correctly contracted the pelvic floor muscles. The reference value is determined based on the user's weight and / or physical characteristics.

[0016] In a preferred embodiment: the main control module and the airbag are arranged along the length direction of the base; the main control module is used to control the inflation and deflation of the airbag.

[0017] In a preferred embodiment: taking the end of one side of the airbag facing the main control module as the vertex, connecting the two side edges of the main control module along the width direction, the angle between the two connecting lines is 10°-50°.

[0018] In a preferred embodiment, after the airbag is inflated, the width and height of the upper surface of the airbag along the length direction are the same at all locations.

[0019] In a preferred embodiment: the main control module is connected to the app for communication, and the main control module feeds back to the app a signal indicating that the pressure value remains unchanged or a signal indicating that the pressure value changes over time.

[0020] In a preferred embodiment: the main control module compares the signal of pressure value changing with time with the standard signal to generate pelvic floor muscle strength assessment and pelvic floor muscle status assessment.

[0021] In a preferred embodiment: the main control module makes training suggestions based on the pelvic floor muscle strength assessment and the pelvic floor muscle status assessment.

[0022] In a preferred embodiment: the training suggestions include training courses and single training duration.

[0023] In a preferred embodiment: the main control module controls the inflation and deflation of the airbag through an air pump and an air release valve.

[0024] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0025] 1. The present invention provides a pelvic floor muscle repair instrument with bidirectional feedback. First, the main control seat can drive the bag to inflate and deflate, thereby prompting the user to contract the pelvic floor muscles during inflation and relax the pelvic floor muscles during deflation, so that the user can complete the Kegel exercise. This is the front feedback. And the user can also be reminded when the user does not contract the pelvic floor muscles during inflation to ensure that the user can perform Kegel training as required. And only when the user completes the Kegel training correctly will the value of the pressure sensor be recorded and the pressure-time curve be drawn. In this way, it can be ensured that the values ​​on the pressure-time curve are all values ​​that effectively complete the Kegel training, and the user's pelvic floor muscle condition can be evaluated more accurately, so that the user has a full and correct understanding of the training situation. This is the back feedback.

[0026] 2. The present invention provides a pelvic floor muscle repair device with two-way feedback, which can achieve three-axis positioning and completely solve the problem that such products cannot be correctly positioned; because the main control seat and the airbag are arranged along the length direction of the base, the main control seat not only serves as an operation panel, but also can achieve horizontal positioning of the user's sitting position. When the user sits on the pelvic floor muscle repair device to use it, due to the existence of the main control seat, the user's legs automatically spread apart at a certain angle and basically fit the side of the main control seat, so that the user can experience non-invasive Kegel exercises more comfortably, which is horizontal positioning; in addition, the airbag itself has a symmetrical shape, and the width and height of the upper surface of the entire airbag after the bulge are consistent. When the user uses this product for training, as long as he sits on the airbag, whether he is forward or backward, the Kegel exercise can easily squeeze the airbag, which is longitudinal positioning. Therefore, three-axis positioning can be achieved to ensure that users sit in the correct position to start Kegel training, and the training is more effective and accurate.

[0036] The technical solutions 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; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] refer to Figure 1-Figure 6This embodiment provides a pelvic floor muscle repair instrument with bidirectional feedback, including: a pelvic floor muscle repair device and a terminal program; a data connection is established between the pelvic floor muscle repair device and the terminal program; in this embodiment, the terminal program is an APP installed on the user's smartphone or tablet computer.

[0040] The pelvic floor muscle repair device includes a base 1 and a main control seat 2 and an airbag 3 placed on the base 1; the main control seat 2 and the airbag 3 are arranged along the length direction of the base 1; the main control seat 2 is used to control the inflation and deflation of the airbag 3; the airbag 3 is provided with a pressure sensor on the side facing the user, which is used to detect the pressure applied by the user to the airbag 3 and send it to the terminal program: because the user needs to contract the pelvic floor muscles when doing Kegel training, the contracted pelvic floor muscles will squeeze the airbag 3, causing the detection value of the pressure sensor to increase, so by detecting this pressure value, it is possible to judge whether the user has performed the Kegel exercise correctly, and the state of the pelvic floor muscles can also be evaluated by the size of the pressure value.

[0041] Therefore, a detection program is stored in the terminal program, so that the terminal program determines whether the user has completed the upward contraction of the pelvic floor muscles according to the value fed back by the pressure sensor:

[0042] 1) Within N seconds after the airbag 3 starts to inflate, determine whether the pressure value detected by the pressure sensor increases. If so, determine that the user has correctly contracted the pelvic floor muscles, and go to step 3. Otherwise, determine that the user has not correctly contracted the pelvic floor muscles, and go to step 2; specifically: determine whether the pressure value detected by the pressure sensor increases, and whether the pressure value exceeds the reference value. If so, determine that the user has correctly contracted the pelvic floor muscles, otherwise determine that the user has not correctly contracted the pelvic floor muscles, wherein the reference value is determined according to the user's weight and / or physical characteristics. Before use, the user sits on the pelvic floor muscle repair instrument, and the pelvic floor muscle repair instrument is provided with a reference value triggering unit, which can be manually triggered by the user, or sound triggered, or automatically triggered after the pelvic floor muscle repair instrument detects that the user is sitting on the pelvic floor muscle repair instrument. According to the user's physical characteristics, such as pelvic shape, sitting posture, and weight, the pelvic floor muscle repair instrument will obtain the pressure value recorded by the pressure sensor, which is the reference value. The pressure sensor can be a gravity sensor or a pressure sensor.

[0043] 2) Stop recording the pressure value of the pressure sensor, feed back a signal that the pressure value remains unchanged to the user, and return to step 1; and, in addition to sending feedback to the user in step 2, the airbag can also be controlled to maintain the current inflation state, or the air pressure of the airbag can be controlled to gradually increase to force the user to correctly contract the pelvic floor muscles; provide multiple feedback to the user, including visually or auditorily reminding the user that the pressure value remains unchanged so that the user can visually or auditorily perceive that they have not correctly contracted the pelvic floor muscles, and controlling the airbag state to remain unchanged or change, or the motor vibration to remind the user's body parts, so that the user can perceive that they have not correctly contracted the pelvic floor muscles.

[0044] Providing users with feedback that the pressure value remains unchanged is a significant improvement over existing technologies. It is equivalent to reminding users that they have not correctly contracted their pelvic floor muscles, and that the current incorrect training method cannot be continued. Continuing the incorrect training will not be recorded and is invalid training, which should be adjusted in time.

[0045] 3) Record the pressure value of the pressure sensor, feed back the signal of the pressure value change to the user, and return to step 1. The pressure value change signal is reminded to the user visually or auditorily, and the airbag is controlled to contract according to the set frequency to remind the user's body parts, so that the user can perceive the correct contraction of the pelvic floor muscles from the visual or auditory sense and body parts. Through the multi-feedback method, the user can be reminded in time to do Kegel exercises correctly, solving the problem that the existing pelvic floor muscle instrument cannot remind the user to do Kegel exercises correctly in time.

[0046] In this embodiment, the main control module is connected to the app for communication, and the main control module feeds back the signal of the constant pressure value or the signal of the pressure value changing over time to the app. The app can then provide feedback to the user based on these feedback signals, and the feedback form includes at least one of a pressure-time curve graph, a pressure-time bar graph, a pressure-time data table, a prompt light, and a prompt sound. In this embodiment, the pressure-time curve graph is taken as an example. The app can be installed on the user terminal to view or listen to the pressure value changes or unchanged conditions in real time.

[0047] The above-mentioned pelvic floor muscle repair instrument can first realize that the main control seat 2 drives the airbag to inflate and deflate, thereby prompting the user to contract the pelvic floor muscles when inflating and relax the pelvic floor muscles when deflated, so that the user can complete the Kegel exercise. This is the front feedback. And it can also remind the user when the user does not contract the pelvic floor muscles during inflation to ensure that the user can perform Kegel training as required. And only when the user completes the Kegel training correctly will the value of the pressure sensor be recorded and the pressure-time curve will be drawn according to the signal of the pressure value change. In this way, it can be ensured that the values ​​on the pressure-time curve are all values ​​that effectively complete the Kegel training, and the user's pelvic floor muscle condition can be more accurately evaluated, so that the user has a full and correct understanding of the training situation. This is the back feedback.

[0048] In order to facilitate users to see the effect of training, the terminal program stores the drawn pressure-time curve in the form of date. In this way, users can call up curves of different dates at any time for comparison and intuitively see the repair status of pelvic floor muscles, thereby increasing motivation and willingness to use the repair instrument.

[0049] In addition, the terminal program can also calibrate and generate a standard curve when users of different weights sit down. The terminal program compares the drawn pressure-time curve with the standard curve to generate a pelvic floor muscle strength assessment and a pelvic floor muscle status assessment. After the assessment is completed, the terminal program makes training suggestions based on the pelvic floor muscle strength assessment and the pelvic floor muscle status assessment. Users can perform Kegel exercises according to the training course and single training duration in the training suggestions to better achieve the effect of repairing the pelvic floor muscles.

[0050] Finally, the terminal program can also increase the user's interest in Kegel training by playing fun games. For example, the training time is 5 minutes, and each 30 seconds is a cycle, with 20 seconds of training and 10 seconds of rest in 30 seconds. After each cycle, the user's training situation is scored, and if the score reaches a certain value, the user can upgrade in the next training cycle.

[0051] In a specific embodiment, in order to more conveniently receive feedback signals, a display module is provided on the pelvic floor muscle repair device, and the display module is used to receive the signal sent by the main control module to feedback to the user that the pressure value remains unchanged, or to feedback to the user that the pressure value changes over time.

[0052] The above mainly describes the guidance of Kegel exercises. There is another problem with this type of device, that is, the user cannot accurately locate the position of the pelvic floor muscles, and the device in this embodiment can achieve three-axis positioning, which completely solves the problem that this type of product cannot be correctly positioned; because the main control seat 2 and the airbag 3 are arranged along the length direction of the base 1, the main control seat 2 not only serves as an operation panel, but also can realize the horizontal positioning of the user's sitting position. When the user sits on the pelvic floor muscle repair device and uses it, due to the existence of the main control seat 2, the user's legs automatically spread apart at a certain angle, and basically fit the side of the main control seat 2, so that the non-invasive Kegel exercise can be experienced more comfortably, which is horizontal positioning; in addition, the airbag 3 itself has a symmetrical shape, and the width and height of the upper surface of the entire airbag 3 after the bulge are consistent. When the user uses this product for training, as long as he sits on the airbag 3, whether it is forward or backward, the Kegel exercise can easily squeeze the airbag 3, which is longitudinal positioning. Therefore, three-axis positioning can be achieved to ensure that users sit in the correct position to start Kegel training, and the training is more effective and accurate.

[0053] Specifically, with the end of one side of the airbag 3 facing the main control seat 2 as the vertex, the angle between the two lines along the two side edges of the main control seat 2 along the width direction is 10°-50°. The setting of the main control seat 2 can play a role in leg positioning. When the user sits on the airbag 3 on the pelvic floor muscle repair instrument, the legs are leaning against the main control seat 2. At this time, the angle of the legs is roughly 10°-50°, which can achieve a better training effect. In the process without guidance, users often arbitrarily open their legs at a wide angle and cannot achieve a good training effect. On the contrary, when the user clamps the legs too tightly, the contraction exercise cannot be done well, which will also affect the training effect. Therefore, the main control seat 2 is used as a reference to better guide the user's sitting posture.

[0054] In this embodiment, the main control seat 2 controls the inflation and deflation of the airbag 3 through the air pump 4 and the deflation valve 5. The typical connection structure is as follows: Figure 7 In addition, the pelvic floor muscle repair device also includes a vibration motor 6. When the pressure sensor detects that the pressure value becomes larger, it is judged that the user contracts the pelvic floor muscles to squeeze the airbag 3, and the vibration motor 6 vibrates to provide feedback to the user; the vibration amplitude or frequency of the vibration motor 6 is negatively correlated with the pressure value detected by the pressure sensor.

[0055] The above description is only a preferred specific implementation mode of the present invention, and does not limit the patent scope of the present invention. Any technical equivalent changes made using the contents of the present invention specification shall fall within the protection scope of the present invention.
