Description

Technical Field

[0001] This invention relates to the field of excretory medical devices, and more particularly to a training device for defecation dysfunction. Background Technology

[0002] Among patients with existing bowel problems, some have issues due to rectal sphincter dysfunction. Therefore, during treatment, patients need to perform hip-lifting exercises to rehabilitate the rectal sphincter, restore its function, and thus control bowel movements.

[0003] However, during training, medical staff typically explain the process to patients and guide them through hip-lifting exercises. Because the rectal sphincter is located inside the body, no obvious changes are visible on the external skin during these exercises. This makes it difficult for medical professionals to observe and assess the situation externally, and thus, to determine whether the patient's muscle training has met the required standards. Consequently, the rehabilitation process often proves ineffective.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0009] Multiple pressure sensors, each pressure sensor is connected to a separate airbag component;

[0010] The data processor is electrically connected to the barometric pressure sensor.

[0011] The inflatable air bladder is compressed by the anal sphincter, causing multiple pressure sensors to detect changes in pressure. The data processor then issues a prompt based on a comparison of the changes in pressure from the multiple pressure sensors with a preset pressure.

[0012] Optionally, the airbag component includes: an airbag rubber, with both axial ends of the airbag rubber fixed to the support member, and an air cavity formed between the airbag rubber and the outer wall of the support member;

[0013] The pressure sensor is located inside the air chamber and connected to the outer wall of the support.

[0014] Optionally, a recessed connecting groove is provided on the outer wall of the support member and on both sides of the airbag member. The two ends of the airbag rubber cover the recessed connecting groove. A first sealing ring is provided on the outer sleeve of the recessed connecting groove. A fixing ring is connected to the outer wall of the support member. The fixing ring is sleeved on the outside of the first sealing ring so that the first sealing ring squeezes the end of the airbag rubber.

[0015] Optionally, a groove is provided on the outer wall of the support member, and a through hole is provided at the bottom of the groove;

[0016] The pressure sensor is installed inside the settling tank, and the cable of the pressure sensor passes through the through hole;

[0017] An installation gap is formed between the pressure sensor and the side wall of the settling tank, and the installation gap is filled with a layer of sealant.

[0018] Optionally, multiple airbag components are non-uniformly distributed along the axial direction of the support component;

[0019] Along the axial direction of the support member, the distribution density of multiple airbag components at both ends is less than that in the middle.

[0020] Optionally, the data processor obtains the detection pressure based on the changing pressure of multiple non-uniformly distributed barometric pressure sensors, and the detection pressure F = (k1*F1 + k2*F2 + k3*F3 + k4*F4 + ... + Kn*Fn) / n;

Fn is the measured pressure change of the rear barometric pressure sensor Nn, and n is the total number of barometric pressure sensors;

[0022] k1+*k2+*k3+*k4+…+*Kn=1, k1>k2>k3>k4>…Kn.

[0023] Optionally, along the axial direction of the support member, the volume of the multiple airbags in the middle after expansion is smaller than the volume of the multiple airbags at both ends after expansion.

[0025] Optionally, the defecation dysfunction training device includes a detection host, which is located outside the support, and a data processor is located inside the detection host and electrically connected to the air pressure sensor via a cable.

[0027] The reminder device is electrically connected to the data processor and is used to receive reminder information issued by the data processor.

[0028] Beneficial Effects: This invention provides a defecation dysfunction training device. During anal sphincter training, a support is inserted into the patient's anus, and the device is activated. The inflatable air bladder expands, compressing the anal sphincter. Initial air pressure values ​​are detected by air pressure sensors at different axial positions. The patient performs Kegel exercises as instructed. During these exercises, the anal sphincter compresses the air bladder. At this point, the air pressure sensors detect the maximum air pressure value. The data processor receives the maximum air pressure value from the air pressure sensors and compares it with the initial air pressure value, calculating the difference to obtain the change in air pressure value. The change in pressure from multiple air pressure sensors is compared with a preset pressure to determine if the preset requirements are met. If the preset requirements are met, the Kegel exercise is considered successful; otherwise, it is considered unsuccessful. Information prompts are provided based on the success rate, encouraging the patient to improve or / and providing time reminders. This ensures the patient's Kegel exercises meet training standards, improves rehabilitation effectiveness, and reduces the burden on medical staff. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0036] like Figure 1 , Figure 2As shown, this embodiment proposes a defecation dysfunction training device, which can be an integrated structure or a split structure. If a split structure is adopted, it mainly includes: a sensor rod 10 and a detection host 20. The sensor rod 10 and the detection host 20 are connected via cable or wireless connection. For ease of structural description, the axial direction of the sensor rod 10 is taken as the front-back direction, the front end of the sensor rod 10 is used to insert into the patient's anus, and the end that is easy to hold is the rear end. Taking the split structure as an example, the sensor rod 10 mainly includes: a support member 100, multiple airbags 200, and multiple air pressure sensors 300. The support member 100 is cylindrical and extends a predetermined length along the axial direction. This length is greater than the vertical length of the human anal sphincter (when standing), so that when inserted into the patient's anus, it can pass through the entire area of ​​the anal sphincter, and there is also a handle position on the outside for easy gripping. Multiple airbag components 200 are axially spaced on the support member 100. Each airbag component 200 has an air chamber 220, which is independently configured and used for inflation. The arrangement of multiple airbag components 200 allows for a smaller diameter in the contracted state, facilitating insertion into the anus. Inflation fills the anus, and the inflated state allows for sensitive response to pressure changes via the contraction of the anal sphincter. Multiple pressure sensors 300 are connected one-to-one with each airbag component 200, and each pressure sensor 300 is connected to an air chamber 220, allowing for individual sensing of pressure changes in each airbag component 200. By using multiple pressure sensors 300 along the axial direction, pressure changes in different areas of the anal sphincter in the vertical direction can be detected, comprehensively considering the contraction amount at various locations of the anal sphincter, thus making the detection more sensitive and accurate. The detection host 20 mainly includes a data processor 21. The data processor 21 is electrically connected to the pressure sensor 300. The detection host 20 is also connected to multiple airbag components 200 and is used to supply air to each airbag component 200. The inflated airbag component 200 is compressed by the anal sphincter, causing the multiple pressure sensors 300 to detect pressure changes. The data processor 21 issues a prompt based on a comparison of the pressure changes from the multiple pressure sensors 300 with a preset pressure. In addition to detecting pressure changes, it also detects the duration for which the pressure change exceeds the preset pressure. It checks whether the duration meets a required time, such as 3-5 seconds.

[0037] This embodiment adopts a split design, which can reduce the number of components inside the sensing rod 10, simplify the structural design, and facilitate the miniaturization of the sensing rod 10.

[0038] Additionally, a scale is provided on the side of the support member 100. The length of the support member 100 inserted into the anus can be read visually through the scale. A hemispherical top 110 is provided at the front end of the support member 100, which guides the sensor rod 10 to more easily enter the patient's anus. A central cavity 120 is provided inside the support member 100 to facilitate the insertion of cables and trachea.

[0039] If the defecation dysfunction training device adopts an integrated structure, then multiple airbag components 200, multiple air pressure sensors 300 and data processor 21 are all integrated on the support component 100 to form an integrated sensing rod 10, while the corresponding detection host 20 can be set separately as an accessory.

[0040] The working principle and effect of the defecation dysfunction training device in this embodiment are as follows: When training the patient's anal sphincter, the support 100 is inserted into the patient's anus and the training device is started, so that the air bladder 200 is inflated and expands. The expanded air chamber 220 can squeeze the anal sphincter, and the initial air pressure value at this time is detected by the air pressure sensors 300 at different axial positions. The patient performs Kegel exercises according to the instructions. During the exercises, the anal sphincter muscles compress the air bladder 200. At this time, the pressure sensor 300 detects the maximum pressure value. The data processor 21 receives the maximum pressure value from the pressure sensor 300 and the initial pressure value, calculates the difference to obtain the change pressure value, and compares the change pressure from multiple pressure sensors 300 with the preset pressure to see if the preset requirements are met. If the preset requirements are met, the Kegel exercise is considered successful; if not, it is considered unsuccessful. Information prompts are given based on the success or failure status, prompting the patient to improve or / and providing a timer reminder. This ensures that the patient's Kegel exercises meet the training standards, improves the training and rehabilitation effect, and reduces the burden on medical staff. Moreover, the expansion of the air bladder 200 can provide some resistance to the contraction of the anal sphincter muscles, thus applying resistance to the training and further aiding in the training of the anal sphincter muscles.

[0041] like Figure 2 , Figure 3As shown, further, the airbag component 200 in this embodiment includes an airbag rubber 210, with its axial ends fixed to the support component 100. An air cavity 220 is formed between the airbag rubber 210 and the outer wall of the support component 100. The air pressure sensor 300 is located inside the air cavity 220 and connected to the outer wall of the support component 100. This structure allows the air pressure sensor 300 to be directly placed in the air cavity 220 of the airbag component 200, thus directly sensing changes in air pressure within the air cavity 220. Even minute changes in air pressure can be detected by the air pressure sensor 300, thereby improving detection sensitivity and significantly enhancing the detection accuracy of the entire training device.

[0042] like Figure 2 As shown, further, in this embodiment, recessed connecting grooves 130 are respectively provided on the outer wall of the support member 100 and on both sides of the airbag member 200. The two ends of the airbag rubber 210 are covered in the recessed connecting grooves 130. A first sealing ring 140 is sleeved on the recessed connecting grooves 130. A fixing ring 150 is connected to the outer wall of the support member 100. The fixing ring 150 is sleeved on the outside of the first sealing ring 140 so that the first sealing ring 140 squeezes the end of the airbag rubber 210. The recessed connecting grooves 130 in the front and rear directions are all arranged around the outer wall of the support member 100. The two ends of the airbag rubber 210 are pressed into the recessed connecting grooves 130 on the front and rear sides by the first sealing ring 140, and then fixed by the fixing ring 150, so that the air cavity 220 is sealed and there is no air leakage.

[0043] like Figure 2 As shown, further, in this embodiment, a groove 160 is provided on the outer wall of the support member 100, and a through hole is provided at the bottom of the groove 160. The pressure sensor 300 is disposed in the groove 160, and the cable of the pressure sensor 300 passes through the through hole and extends into the central cavity 120. By disposing of the pressure sensor 300 in the groove 160, the pressure sensor 300 is prevented from protruding from the outer wall of the support member 100, thus avoiding any bumping sensation when the support member 100 is inserted into the anus, making the patient more comfortable. An installation gap is formed between the pressure sensor 300 and the side wall of the groove 160, and the installation gap is filled with a sealant layer 310. The sealant bonding and fixing provides two advantages: firstly, it forms a simple fixing method, which is convenient for production; secondly, the sealant layer 310 seals the gap and prevents air leakage. In this embodiment, the multiple pressure sensors 300 are staggered, and adjacent pressure sensors 300 are not located in a straight line in the front-back direction. For example, they can be spirally staggered around the outer wall of the support member 100. This allows for effective sensing of the anal sphincter contraction around the anus, enabling a comprehensive examination and analysis of the anal sphincter contraction in all directions around the anus, thus improving detection accuracy.

[0044] In another structure, the air chamber 220 can also be in the form of an independent airbag, with the individual airbag directly placed on the outer wall of the support 100, and the air pressure sensor 300 connected to the airbag through a pipe to sense the air pressure change inside the airbag and realize the detection function.

[0045] In this embodiment, the multiple airbag components 200 can be evenly distributed along the axial direction of the support member 100. If a uniform distribution is adopted, all the airbag components 200 need to be designed relatively densely, resulting in an increase in the number of air pressure sensors 300.

[0046] like Figure 3 As shown, in this embodiment, the airbag component 200 is ventilated using an air pipe connector 230 and a flexible hose. A connector mounting countersunk hole 170 is provided on the outer wall of the support component 100. The air pipe connector 230 is screwed onto the outer wall of the support component 100, and is located within the connector mounting countersunk hole 170. A second sealing ring 240 is filled between the air pipe connector 230 and the inner wall of the connector mounting countersunk hole. The flexible hose extends into the central cavity 120 of the support component 100 and can be led out from the rear end of the support component 100 to connect to an external air pump 22 for inflation. The air pipe connector 230 in one air chamber 220 is circumferentially offset from the air pressure sensor 300.

[0047] like Figure 1 , Figure 5 As shown, further in the split design, the detection host 20 of the defecation dysfunction training device is separately installed outside the sensing rod 10, while the data processor 21 is installed inside the detection host 20 and electrically connected to the air pressure sensor 300 via a cable. This approach reduces the structure on the sensing rod 10, making it more convenient to use.

[0048] Furthermore, the detection host 20 is also equipped with an air pump 22 and an alert device 23. The air pump 22 is connected to the air tube (hose) of the air chamber 220 and is used to inflate the airbag component 200. The alert device 23 is electrically connected to the data processor 21 and is used to receive alert information issued by the data processor 21.

[0049] The reminder device 23 may include a speaker, an indicator light, and / or a display screen. If a display screen is used, it can visually display usage instructions and training methods.

[0050] Example 2

[0051] like Figure 4As shown, this embodiment improves the distribution of multiple airbag components in Embodiment 1. Specifically, in this embodiment, the multiple airbag components are non-uniformly distributed along the axial direction of the support member. The distribution pattern is as follows: along the axial direction of the support member, the distribution density of the multiple airbag components at both ends is less than the distribution density in the middle.

[0052] Because the anal sphincter exerts greater pressure in the middle section during contraction, compared to less pressure at the ends, the measurement index relies on the core pressure in the middle. Therefore, using pressure sensors with a higher density in the middle section for pressure detection effectively captures the core pressure of the anal sphincter, while using pressure sensors with a lower density at the ends provides auxiliary detection of the peripheral contractile capacity. Combining these two methods allows for a comprehensive assessment of the anal sphincter's contractile ability.

[0053] Furthermore, with a fixed support length, this configuration allows for more accurate testing for both adults and children. Specifically, the length of the anal sphincter muscles differs between adults and children; adults' muscles are longer, while children's are shorter. Therefore, during testing, the support extends a greater length into the adult's anus (fully inserted) and a shorter length into the child's (half-inserted). When only half-inserted, the remaining half does not detect pressure changes. Therefore, data analysis can exclude the number of pressure sensors that are not inserted and only count those inserted into the anus. Because the front end is sparse and the middle section is dense, the middle section still enters the child's anus for pressure sensing. The densely packed pressure sensors in the middle can still detect pressure. Furthermore, based on the number of pressure sensors at the rear that do not produce pressure changes, the patient's age range can be determined, and preset pressures can be automatically matched to patients of different ages. This improves the user experience and makes this bowel dysfunction training device more intelligent.

[0054] The preset pressure in this embodiment was determined through multiple experimental tests before the instrument was manufactured. Furthermore, in actual use, doctors can adjust the preset pressure according to the patient's needs.

[0055] Furthermore, the data processor obtains the detection pressure based on the changing pressure of multiple non-uniformly distributed barometric pressure sensors, and the detection pressure F = (k1*F1 + k2*F2 + k3*F3 + k4*F4 + ... + Kn*Fn) / n. Where k1-Kn are weighting coefficients, F1 is the measured pressure change of the central barometric pressure sensor N1, F2 is the measured pressure change of the barometric pressure sensor N2 located in front of the central barometric pressure sensor N1, F3 is the measured pressure change of the barometric pressure sensor N3 located behind the central barometric pressure sensor N1, F4 is the measured pressure change of the barometric pressure sensor N4 located in front of the barometric pressure sensor N2, F5 is the measured pressure change of the barometric pressure sensor N5 located behind the barometric pressure sensor N3, ..., Fn is the measured pressure change of the rear barometric pressure sensor Nn, and n is the total number of barometric pressure sensors; k1+*k2+*k3+*k4+……+*Kn=1, k1>k2>k3>k4>……Kn. In the specific method,

[0056] By weighting the pressure readings from each pressure sensor as described above, the measurement from the middle pressure sensor is made more effective than those from the two ends. This ensures that the pressure sensor in the middle position more accurately detects the contraction of the core area of ​​the anal sphincter. This allows for accurate detection of the anal sphincter contraction process with fewer pressure sensors.

[0057] In this embodiment, the weighting value k1 is the largest, k1 = 2k2; k2 = 1.8k3; k3 = 1.7k4; k4 = 1.6k5. This ensures the stability of the detection of contraction in the core area of ​​the anal sphincter and the comprehensiveness of the data.

[0058] In the specific structure, for example, the number of pressure sensors is set to 11: k1 = 2k2, k2 = 1.8k3, k3 = 1.7k4, k4 = 1.6k5, k5 = 1.5k6, k6 = 1.4k7, k7 = 1.3k8, k8 = 1.2k9, and k9 = 1.1k10. This structure can meet the testing needs of all patients. Test results show that by detecting pressure at different locations, the contraction of the anal sphincter at different positions during exertion can be accurately reflected. Moreover, when determining whether training standards have been met, the pressure changes obtained using this method are highly accurate, comprehensive, and more stable than other setups.

[0059] Example 3

[0060] like Figure 4As shown, this embodiment is a further improvement on Embodiments 1 and 2. Specifically, along the axial direction of the support member, the volume of the multiple air bladders in the middle after expansion is smaller than the volume of the multiple air bladders at both ends after expansion. This creates a structure that is large at both ends and small in the middle. When inserted into the anus, the larger air bladders at both ends exert a certain amount of pressure on the anal sphincter, thereby providing a certain limiting function for the support member. During the contraction and relaxation of the muscles during anal sphincter contraction, the support member usually does not move back and forth due to the limiting effect of the larger air bladders at both ends. This avoids the problem of inaccurate detection position caused by the sliding of the support member during muscle relaxation. It also avoids the problem of the support member easily slipping out when the muscles are relaxed.

[0061] In addition, by making the airbag components, which have different inflated sizes, sparser airbag components at the front and rear ends can create a larger interlocking gap between adjacent airbag components. This interlocking gap allows for better restraint by engaging with human tissue.

[0062] like Figure 4 As shown, in this embodiment, the vertices of the multiple inflated airbag components are arranged in an arc shape. The arc shape formed by the outer airbag components better matches the contour of the anus, resulting in a better limiting effect.

[0063] In summary, the defecation dysfunction training device of the present invention compares the changes in pressure from multiple air pressure sensors with a preset pressure during anal sphincter training to see if a preset requirement is met. The preset requirement can be a pressure requirement or a time requirement. For example, if the preset requirement is met, the anal sphincter training process is considered qualified; if it is not met, the anal sphincter training process is considered unqualified. Information prompts are given based on the qualification status to prompt the patient to improve or / and time reminders are provided, thereby enabling the patient's anal sphincter training to meet the training standards, improving the training and rehabilitation effect, and reducing the burden on medical staff.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
