Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a bowel sound monitoring device. Background Technology

[0002] The incidence of intestinal motility disorders is high, such as chronic constipation and irritable bowel syndrome. Diagnosis of these diseases relies heavily on the patient's subjective experience and is significantly influenced by the patient's own condition. Doctors typically perform multiple abdominal X-rays to conduct colonic transit tests or insert manometry devices to measure intestinal manometry, which objectively reflects whether intestinal motility is normal. However, in some intestinal motility disorders (such as Crohn's disease and ulcerative colitis), abnormal intestinal motility can be reflected by bowel sounds, thus using bowel sound signals as objective evidence to aid in diagnosis.

[0003] Traditionally, bowel sound monitoring involves doctors listening to the abdomen with a stethoscope. However, bowel sounds are not only irregular but also periodic with relatively long cycles (approximately 80–150 minutes). To fully capture the characteristics of bowel sounds, doctors need to spend a considerable amount of time listening, and for some diseases, monitoring may even be necessary for 24 hours for better diagnostic results. This not only easily leads to doctor fatigue but also makes it difficult to allocate sufficient time to each patient when there are many patients, hindering long-term continuous monitoring of bowel sounds and affecting diagnostic accuracy.

[0004] Therefore, related technologies utilize wearable monitoring devices for long-term monitoring of bowel sounds. Specifically, a microphone and control components are mounted on a belt. The belt is strapped to the patient's abdomen, the microphone collects bowel sound data, and the control components store and process this data, thus enabling long-term monitoring. To avoid cross-infection, the monitoring device must be cleaned and disinfected after each patient's use. After prolonged use, the belt is most prone to wear and tear, and the microphone may also be damaged, requiring replacement. However, in existing bowel sound monitoring devices, the control components and microphone are non-removably fixed to the belt. This not only makes it difficult to clean and disinfect each part appropriately according to its characteristics, reducing the effectiveness of cleaning and disinfection and thus lowering the safety of bowel sound monitoring, but also makes it difficult to replace damaged parts, especially the easily damaged belt and microphone. The belt, microphone, and control components must be discarded together, increasing the cost of bowel sound monitoring.

[0005] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0062] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] It should be noted that in this invention, the terms "first" and "second" are used only to facilitate the description of two or more structures or components that are identical or similar in structure and / or function, and do not indicate any special limitation on order and / or importance.

[0064] In this invention, "and / or" merely describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0065] In this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal connection of two components; it can be a mechanical connection or a communication connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0066] In this invention, "front" in "front side," "back side," "anterior," and "rear" refers to the direction away from the patient after the bowel sound monitoring device is installed on the abdomen via the waist belt 1. Figure 1In the context of "front," "back" refers to the opposite direction to "front," such as... Figure 1 Behind the patient. "Left" and "right" refer to the left and right sides when facing the patient, respectively. Figure 1 The left and right sides of the middle.

[0067] The background technology of this application will be described in detail below.

[0068] In related technologies, wearable bowel sound monitoring devices are used to monitor bowel sounds. These devices typically include a waist belt and a microphone and control components mounted on the waist belt. By attaching the waist belt to the patient's abdomen, the microphone can continuously collect bowel sound signals, and the control components can store and process the collected bowel sound signals, thereby achieving long-term monitoring of bowel sounds.

[0069] To save on the cost of bowel sound monitoring, the devices are often reused, which inevitably carries the risk of cross-infection. To avoid cross-infection, all parts of the monitoring device must be cleaned and disinfected after each patient's use. During the disinfection process, each part is typically cleaned and disinfected according to its characteristics. For example, the belt and microphone often come into direct contact with the body and require cleaning and disinfection to thoroughly eliminate germs. The control components, however, have minimal or no contact with the body and, considering their internal electronic components, are generally disinfected by wiping.

[0070] After prolonged use, the belt is prone to loss of elasticity due to repeated binding, or it is the most easily worn and thus the most likely to be damaged, followed by the microphone. Furthermore, within the entire bowel sound monitoring device, the belt and microphone have relatively low manufacturing costs, while the control components have relatively high manufacturing costs.

[0071] In existing bowel sound monitoring devices, the belt, microphone, and control components are fixed together in a non-detachable manner. This makes it difficult to clean and disinfect each part separately according to its working characteristics after each use. Often, only wiping disinfection is possible, making it difficult to thoroughly disinfect the belt and microphone, which come into direct contact with the human body. This reduces the effectiveness of cleaning and disinfection, increases the risk of cross-infection, and consequently reduces the safety of bowel sound monitoring. It also makes it difficult to replace damaged parts, especially when only the belt or microphone, which has a lower manufacturing cost, is damaged. In such cases, the belt and microphone, along with the more expensive control components, must be discarded, thus increasing the cost of bowel sound monitoring.

[0072] Please refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the bowel sound monitoring device provided in an embodiment of the present invention from one perspective. Figure 2 for Figure 1 The exploded view of the bowel sound monitoring device shown is shown. Figure 3 for Figure 1 The diagram shows the structure of the waist belt in the bowel sound monitoring device from one perspective. Figure 4 for Figure 1 The diagram shows the structure of the waist belt in the bowel sound monitoring device from another perspective. Figure 5 for Figure 1 The diagram shows the structure of the control component in the bowel sound monitoring device from one perspective. Figure 6 for Figure 1 The diagram shows the structure of the control component in the bowel sound monitoring device from another perspective.

[0073] In the embodiments provided by the present invention, such as Figure 1 , Figure 2 As shown, the bowel sound monitoring device includes a waist belt 1, a control assembly 2, and at least one pickup assembly 14. The waist belt 1 has a mounting bracket 4 in its middle. The control assembly 2 includes a control panel 10 and a control module (not shown) disposed inside the control panel 10. The mounting bracket 4 has a through-hole 44 in the front-rear direction. The control panel 10 is at least partially located on the front side of the mounting bracket 4. The pickup assembly 14 is detachably disposed on the rear side of the control panel 10, extending rearward from the mounting hole 44. The control panel 10 is connected to the mounting bracket 4 via at least one quick-connect mechanism 5. The pickup assembly 14 and the control module are communicatively connected.

[0074] It is easy to understand that by installing the microphone assembly 14 onto the rear of the control panel 10, and then installing the control panel 10 onto the mounting bracket 4, the bowel sound monitoring device can be assembled. Fixing the waist belt 1 to the patient's abdomen completes the installation of the bowel sound monitoring device on the patient's abdomen. The acquisition end of the microphone assembly 14 extends rearward through the mounting hole 44, allowing it to conform to the patient's skin at the rear of the waist belt 1 to collect bowel sound signals, which are then transmitted to the control module. The control module can store and process the received bowel sound signals.

[0075] In this way, by using the waist belt 1 to fix the bowel sound monitoring device to the patient's abdomen, the sound pickup component 14 can be used to continuously collect bowel sound signals, and the control component 2 can be used to store and process the bowel sound signals. This enables continuous long-term monitoring of bowel sound signals without the need for doctors to operate the device by hand. This frees up the doctor's hands and allows the doctor to dedicate time to diagnosing related diseases based on the stored or processed bowel sound signals. Especially for some diseases that require 24-hour monitoring of bowel sounds, this can save doctors' time to a great extent, and obtaining long-term bowel sound signals can also improve the diagnostic accuracy of related diseases.

[0076] Furthermore, the control component 2 and the waist belt 1, as well as the microphone component 14 and the control component 2, are detachably connected, allowing for quick disassembly of each part. On one hand, after monitoring a patient, each part can be cleaned and disinfected according to its working characteristics. For example, the control component 2, which has less or no contact with the patient, can be wiped and disinfected, while the waist belt 1 and microphone component 14, which directly contact the patient, can be cleaned and disinfected to thoroughly eliminate germs and improve the cleaning and disinfection effect, thereby enhancing the safety of bowel sound monitoring. On the other hand, when the device is damaged due to prolonged use, the damaged part can be quickly replaced, avoiding the need to discard all parts when one part is damaged. Especially when the waist belt 1 or microphone component 14, which is easily damaged but has a lower manufacturing cost, is damaged, only the waist belt 1 or microphone component 14 can be replaced, while the more expensive control component 2 can be retained, thereby reducing the cost of bowel sound monitoring.

[0077] In addition, based on the convenient disassembly of each part, the control component 2 can also be quickly installed onto the belt 1 via the quick-connect mechanism 5, which improves the assembly efficiency of the bowel sound monitoring device and allows monitoring to start quickly, thereby improving the efficiency of bowel sound monitoring.

[0078] Please refer to this as well. Figures 7 to 9 , Figure 7 for Figure 1 Front view, Figure 8 for Figure 7 Sectional view along line AA, Figure 9 for Figure 8 A schematic diagram of the quick-connect mechanism in the unengaged state.

[0079] In actual setup, the specific structure of the quick-connect mechanism 5 is not limited, as long as the control panel 10 and the mounting bracket 4 can be installed and removed without tools.

[0080] Please combine Figure 8In this embodiment, the quick-connect mechanism 5 includes a release block 18, a first elastic element 19, and a locking pin 20. The control panel 10 has a buckle 16. The buckle 16 has a locking hole 43, and the fixing frame 4 has an insertion hole 8, a moving space 45, and an abutment surface 46. The moving space 45 communicates with the insertion hole 8 and extends to the abutment surface 46. The buckle 16 is inserted into the insertion hole 8, and the locking pin 20 is at least partially located within the moving space 45. Both ends of the first elastic element 19 abut against the release block 18 and the abutment surface 46, respectively. The release block 18 is at least partially located outside the control panel 10 and connected to one end of the locking pin 20. The other end of the locking pin 20 is engaged in the locking hole 43 to restrict the movement of the buckle 16 relative to the fixing frame 4. Pressing the release block 18 towards the abutment surface 46 moves the locking pin 20 within the moving space 45, disengaging it from the locking hole 43. Specifically, one end of the locking pin 20 that engages with the buckle 16 is defined as the locking end, and the other end as the connecting end; the locking end of the locking pin 20 can also be as follows: Figure 8 The slope shown is oriented forward.

[0081] When the control panel 10 of the control component 2 is not inserted into the fixing bracket 4 of the belt 1, the locking end of the locking pin 20 is located in the insertion hole 8.

[0082] When the control panel 10 is inserted and connected to the mounting bracket 4, press the control panel 10 towards the mounting bracket 4. The latch 16 enters the insertion hole 8 and presses against the inclined surface of the latching end of the latch pin 20, pushing the latch pin 20 away from the insertion hole 8. The latch pin 20 drives the release block 18 away from the initial position, and the first elastic element 19 is deformed by pressure. As the latch 16 continues to move into the insertion hole 8, the latching end of the latch pin 20 gradually aligns with the latching hole 43 of the latch 16. Under the elastic force of the first elastic element 19, the release block 18 moves towards the initial position and drives the latch pin 20 towards the insertion hole 8 until the latch pin 20 engages with the latching hole 43 of the latch 16. Thus, the rear side of the latching end of the latch pin 20 and the inner side of the latching hole 43 cooperate, as shown. Figure 8 The locking limit is formed on the buckle 16 as shown.

[0083] When it is necessary to disassemble the control component 2, the operator presses the release block 18 towards the contact surface 46. The release block 18 causes the locking pin 20 to move away from the locking hole 43 within the movement space 45, and the first elastic element 19 is simultaneously deformed by pressure. When the locking pin 20... Figure 9 When the locking end of the locking pin 20 disengages from the locking hole 43, the control component 2 can be lifted and removed from the belt 1. After releasing the release block 18, the locking pin 20 returns to its initial position based on the resetting action of the first elastic element 19, ready for the locking assembly of the control component 2.

[0084] In this way, the quick-connect mechanism 5 can be used to quickly assemble the control component 2 and the belt 1, and the control component 2 can be quickly disassembled simply by pressing the release block 18. The operation is very convenient and can greatly improve the disassembly and assembly efficiency of the bowel sound monitoring device. At the same time, the quick-connect mechanism 5 has a relatively simple and compact structure, which is conducive to the compactness of the bowel sound monitoring device.

[0085] Specifically, the connection method between release block 18 and locking pin 20 is not limited.

[0086] In the embodiments of this application, such as Figure 8 As shown, the quick-connect mechanism 5 also includes a connecting rod 21. The moving space 45 includes an interconnected clearance hole 47 and a moving channel 48. The extending direction of the moving channel 48 is parallel to the abutment surface 46; in other words, the moving direction of the locking pin 20 within the moving channel 48 is perpendicular to the moving direction of the release block 18. The clearance hole 47 is located on the side of the moving channel 48 away from the abutment surface 46. The locking pin 20 and the connecting rod 21 are at least partially located within the moving channel 48. One end of the release block 18 and the connecting rod 21 are hinged, and the other end of the connecting rod 21 is hinged to the locking pin 20. Pressing the release block 18 towards the abutment surface 46 causes one end of the connecting rod 21 to move into the clearance hole 47, thereby pulling the locking pin 20 within the moving channel 48 in a direction away from the insertion hole 8.

[0087] Press the release block 18 towards the abutment surface 46. The release block 18 drives the connecting rod 21 to rotate, and one end of the connecting rod 21 moves into the relief hole 47. The connecting rod 21 pulls the locking pin 20 to move away from the insertion hole 8 in the moving channel 48. At the same time, the first elastic element 19 is compressed. Release the release block 18. Under the elastic force of the first elastic element 19, the release block 18 moves away from the relief hole 47 and drives the connecting rod 21 to rotate, so that one end of the connecting rod 21 moves away from the relief hole 47, that is, towards the moving channel 48. The other end of the connecting rod 21 pushes the locking pin 20 to move towards the insertion hole 8 in the moving channel 48.

[0088] In this way, the movement of the release block 18 is transmitted to the locking pin 20 by the connecting rod 21. At the same time, the movement direction of the release block 18 and the movement direction of the locking pin 20 can be set perpendicularly, so that the release block 18 and the locking pin 20 can be arranged in different directions, making the structure of the quick-connect mechanism 5 more compact.

[0089] Furthermore, the number of latches 16 is unlimited. Correspondingly, each quick-connect mechanism 5 can be used for locking and limiting one latch 16 or for locking and limiting two or more latches 16. This application does not impose any restrictions on this.

[0090] As an optional solution, there is at least one set of latches 16, with each set containing two or more latches 16. The number of quick-connect mechanisms 5 and the number of sets of latches 16 are the same and correspond one-to-one. The number of locking pins 20, connecting rods 21, moving channels 48, insertion holes 8, and latches 16 are also the same and correspond one-to-one. That is, for each set of latches 16, there is a quick-connect mechanism 5 that provides locking limit. This quick-connect mechanism 5 is equipped with locking pins 20 that are the same number as the number of latches 16 and correspond one-to-one to perform locking limit. In this way, one quick-connect mechanism 5 can be used to achieve locking limit for two or more latches 16, which improves the connection stability between the control panel 10 and the fixing bracket 4 while ensuring the compactness of the connection structure.

[0091] Furthermore, the arrangement of the clips 16 is not limited. For example, they can be arranged according to the shape of the control panel 10, and the shape of the control panel 10 can match the shape of the fixing bracket 4. The shapes of the two are also not limited.

[0092] Please combine Figures 3 to 5 In this embodiment, both the mounting bracket 4 and the control panel 10 can be rectangular, and their shapes and sizes can match each other. The buckle 16 can be located on the rear side of the control panel 10, and the insertion hole 8 can extend to the front side of the mounting bracket 4, with the abutment surface 46 facing the front of the mounting bracket 4, specifically the front side of the mounting bracket 4. Two sets of buckles 16 can be provided, each set including two buckles 16. The two sets of buckles 16 can be located on the left and right sides of the control panel 10, i.e., the two short sides of the rectangular structure. The four buckles 16 are distributed at the four corners of the rectangle. Correspondingly, the mounting bracket 4 has insertion holes 8 at the four corners of the rectangle corresponding to the positions of the four buckles 16. The quick-connect mechanism 5 has two sets. For each set of buckles 16, the corresponding quick-connect mechanism 5 is provided with two locking pins 20 and two connecting rods 21. The fixed frame 4 is provided with two moving channels 48. The two moving channels 48 can be set along the same center line. The two locking pins 20 are respectively set in the two moving channels 48. The release block 18 of the quick-connect mechanism 5 can be set in the middle position of the fixed frame 4 on the corresponding side.

[0093] During installation, the control panel 10 can be attached to the front side of the mounting bracket 4. The four clips 16 of the control panel 10 are respectively inserted into the four insertion holes 8 of the mounting bracket 4. The left and right sets of clips 16 are respectively locked and limited by the corresponding quick-connect mechanism 5.

[0094] In this way, by setting a set of buckles 16 and a quick-connect mechanism 5 on the left and right sides respectively, the connection between the control panel 10 and the fixing frame 4 can be made stable, while the pin 20 can be set to be shorter to ensure the compactness of the connection structure.

[0095] Please combine Figure 8In this embodiment, the moving space 45 further includes a moving hole 49 communicating with the moving channel 48, extending to the contact surface 46. The control panel 10 has a release hole 9 extending in the front-rear direction, with the release hole 9 and the moving hole 49 corresponding in position. The two release holes 9 corresponding to the two quick-connect mechanisms 5 are located in the middle of the left and right sides of the control panel 10, respectively. The rear side of the release block 18 has a connecting part 50. The first elastic element 19 is a spring, which is sleeved on the connecting part 50. The two ends of the spring abut against the rear side of the release block 18 and the contact surface 46, respectively. The connecting part 50 is at least partially located within the release hole 9 and the moving hole 49. The rear end of the connecting part 50 is hinged to the connecting rod 21, allowing the release block 18 to move along the release hole 9. In this way, the release block 18 and the connecting part 50 form a "T" structure, cleverly realizing the sleeve of the first elastic element 19 and the contact at both ends, as well as the connection between the release block 18 and the connecting rod 21, making the structure of the quick-connect mechanism 5 more compact.

[0096] In the embodiments of this application, such as Figure 4 As shown, the clearance hole 47 can extend to the rear side of the fixing frame 4, so that the space outside the fixing frame 4 can be used to provide additional clearance space for the movement of the connecting rod 21, making the structure of the fixing frame 4 more compact.

[0097] In fact, this application does not limit the type of the first elastic element 19. In specific implementation, the first elastic element 19 can be a spring as described above, or it can be a sleeve-shaped elastomer made of materials with elastic deformation capabilities such as rubber and silicone.

[0098] In the embodiments provided in this application, please refer to Figure 6 It is understood that the bowel sound monitoring device also includes at least one movable component 17. The movable component 17 is located on the rear side of the control panel 10, and the pickup component 14 is located on the movable component 17. The movable component 17 is configured to drive the pickup component 14 to move.

[0099] In contrast to related technologies where the microphone is fixed to the belt and cannot be moved, resulting in a smaller acquisition area and difficulty for new users and non-professionals to place the microphone in the correct monitoring position on the patient's abdomen, making it difficult to acquire comprehensive and accurate bowel sound signals, the bowel sound monitoring device provided in this application embodiment can adjust the position of the microphone component 14 by setting the movable component 17, thereby expanding the acquisition area of ​​bowel sound signals and ensuring that the microphone component 14 is in the correct monitoring position, thus improving the comprehensiveness and accuracy of bowel sound signal acquisition.

[0100] In addition, the movable component 17 can also communicate with the control module, which can quickly and accurately control the movement of the movable component 17 to quickly and accurately adjust the position of the pickup component 14, thereby further improving the accuracy and efficiency of bowel sound monitoring.

[0101] Please refer to this as well. Figure 10 , Figure 10 This is a schematic diagram of the installation structure of the sound pickup component on the moving component in the bowel sound monitoring device provided in an embodiment of the present invention.

[0102] In actual setup, the specific structure of the mobile component 17 is not limited.

[0103] like Figure 10 As shown, in the embodiments provided in this application, the moving component 17 includes a first motor 31, a first mounting plate 32, a first lead screw pair, a first mounting base 35, a second motor 36, a second mounting plate 37, a second lead screw pair, and a second mounting base 40. The first mounting plate 32 is fixed to the rear side of the control panel 10. The first motor 31 is mounted on the first mounting plate 32, and the first mounting base 35 is connected to the output end of the first motor 31 via the first lead screw pair. The second mounting plate 37 is fixed to the first mounting base 35, the second motor 36 is mounted on the second mounting plate 37, and the second mounting base 40 is connected to the output end of the second motor 36 via the second lead screw pair. The microphone assembly 14 is mounted on the second mounting base 40. The first motor 31 and the second motor 36 are communicatively connected to the control module. The first mounting base 35 can move along a first direction, and the second mounting base 40 can move along a second direction. The first and second directions are not parallel; for example, they can be perpendicular to each other.

[0104] The control module can start the first motor 31, which drives the first mounting base 35 to move along the first direction via the first lead screw, thereby adjusting the position of the pickup component 14 along the first direction. Similarly, the control module can start the second motor 36, which drives the second mounting base 40 to move along the second direction via the second lead screw, thereby adjusting the position of the pickup component 14 along the second direction. In this way, the pickup component 14 can be moved quickly and accurately to any position within the set area, ensuring the comprehensiveness of the bowel sound monitoring range and making the structure of the moving component 17 more compact.

[0105] In this embodiment, the first lead screw pair has a first lead screw 33 and a first lead screw nut (not shown in the figure), and the second lead screw pair has a second lead screw 38 and a second lead screw nut (not shown in the figure). The first lead screw 33 is rotatably mounted on the first mounting plate 32 and connected to the first motor 31. The first lead screw 33 passes through the first mounting base 35, and the first lead screw nut is fixed inside the first mounting base 35 and threadedly connected to the first lead screw 33. The second lead screw 38 is rotatably mounted on the second mounting plate 37 and connected to the second motor 36. The second lead screw 38 passes through the second mounting base 40, and the second lead screw nut is fixed inside the second mounting base 40 and threadedly connected to the second lead screw 38. Thus, the structure of the moving assembly 17 is more compact.

[0106] In the embodiments of this application, such as Figure 10As shown, the movable component 17 also includes a first guide post 34 and a second guide post 39. The first guide post 34 and the second guide post 39 are respectively fixed to the first mounting plate 32 and the second mounting plate 37. A first mounting base 35 is slidably disposed on the first guide post 34, and a second mounting base 40 is slidably disposed on the second guide post 39. The first guide post 34 extends along a first direction, and the second guide post 39 extends along a second direction.

[0107] In use, the first guide post 34 can guide the movement of the first mounting base 35, and the second guide post 39 can guide the movement of the second mounting base 40, so as to improve the stability of the movement process of the pickup assembly 14 and further improve the accuracy of the position adjustment of the moving assembly 17.

[0108] The first guide post 34 can pass through the first mounting base 35, and a first slider (not shown in the figure) can be provided in the first mounting base 35. The first slider can be slidably connected to the first guide post 34. The second guide post 39 can pass through the second mounting base 40, and a second slider (not shown in the figure) can be provided in the second mounting base 40. The second slider can be slidably connected to the second guide post 39.

[0109] Please refer to this as well. Figure 11 and Figure 13 , Figure 11 for Figure 10 The diagram shows the structure of the moving component. Figure 12 This is a schematic diagram of the sound pickup component in the bowel sound monitoring device provided in an embodiment of the present invention. Figure 13 for Figure 12 The diagram shows the structure of the pickup assembly on the front side.

[0110] In specific configuration, the connection method between the pickup component 14 and the second mounting base 40 is not limited, as long as it is detachable. In the embodiments of this application, such as Figure 11 As shown, the second mounting base 40 is provided with a slot 42, which can be located on the rear side of the second mounting base 40. The pickup assembly 14 is provided with a plug 29, which can be located on the front side of the pickup assembly 14. The plug 29 is inserted into the slot 42, realizing a detachable connection between the pickup assembly 14 and the second mounting base 40, thereby realizing a detachable connection between the pickup assembly 14 and the control panel 10, enabling quick assembly and disassembly of the pickup assembly 14.

[0111] like Figure 11As shown, the pickup assembly 14 has a first transmission contact 30, and the second mounting base 40 has a second transmission contact 41. The first transmission contact 30 and the second transmission contact 41 are in contact, and the second transmission contact 41 is connected to the control module. Specifically, the first transmission contact 30 can be located on the front side of the pickup assembly 14, and the second transmission contact 41 can be located on the rear side of the second mounting base 40. The insertion block 29 of the pickup assembly 14 is inserted into the slot 42 of the second mounting base 40 to realize the connection between the first transmission contact 30 and the second transmission contact 41, which is convenient and quick to operate.

[0112] The number of insert blocks 29 is unlimited; for example, they can be as follows: Figure 13 The configuration shown has two plugs 29, which can be symmetrically arranged about the axis of the pickup assembly 14. Correspondingly, there are also two slots 42, and the second transmission contact 41 can be located between the two slots 42. The two plugs 29 are respectively inserted into the two slots 42, which can improve the stability of the connection between the pickup assembly 14 and the second mounting base 40.

[0113] Please refer to this as well. Figures 14 to 15 , Figure 14 for Figure 12 The axial sectional view of the pickup assembly shown. Figure 15 for Figure 12 An exploded view of the pickup assembly shown.

[0114] In actual setup, the specific structure of the pickup component 14 is not limited.

[0115] In the embodiments provided in this application, the sound pickup assembly 14 includes a sound pickup module 22, a second elastic member 27, and a connecting seat 28. For example... Figure 14 As shown, the pickup module 22 is connected to the connecting seat 28 via the second elastic element 27. The connecting seat 28 is connected to the control panel 10, specifically via the aforementioned movable component 17. There is a gap between the front end face of the pickup module 22 and the rear end face of the connecting seat 28. The pickup module 22 is connected to the control module and is used to perform the acquisition operation of bowel sound signals and transmit the acquired bowel sound signals to the control module.

[0116] The distance between the pickup module 22 and the connecting seat 28 allows the pickup module 22 to "float" relative to the connecting seat 28. When the bowel sound monitoring device is fixed to the patient's abdomen using the waist belt 1, the rear end face of the pickup module 22 is pressed against the patient's abdominal surface. Under pressure, the second elastic element 27 is compressed, ensuring that the pickup module 22 remains in close contact with the patient's abdomen. Simultaneously, the second elastic element 27 adaptively deflects according to the curvature of the abdominal surface in contact with the pickup module 22, ensuring that the pickup module 22 is suitable for different curvatures of the patient's abdomen. During monitoring, as the patient's breathing causes the abdomen to rise and fall, the deflection of the second elastic element 27 allows the pickup module 22 to adjust its posture in real time to adapt to the curvature of the patient's abdomen. All of these factors contribute to further improving the accuracy of bowel sound monitoring.

[0117] Specifically, the structure of the pickup module 22 is not limited. For example... Figure 15 As shown in the embodiment of this application, the pickup module 22 includes a diaphragm cover 23, a vibrating diaphragm 24, a pickup element 25, and a sound collector 26. The diaphragm cover 23 is disposed on the rear end of the sound collector 26 and has a pickup hole 51 extending in the front-to-back direction. The sound collector 26 has a stepped hole 52 and a first wire passage hole 53 that are interconnected. The stepped hole 52 faces rearward. The vibrating diaphragm 24 is disposed within the pickup hole 51, and the pickup element 25 is disposed within the stepped hole 52. The second elastic element 27 is an elastic tube, which is sleeved on the sound collector 26 and connected to the diaphragm cover 23 at its rear end. The two ends of the elastic tube abut against the front end face of the diaphragm cover 23 and the rear end face of the connecting seat 28, respectively. The connector 28 is provided with a second wire hole 54 that runs through the front and rear directions and a first transmission contact 30. The first transmission contact 30 is at least partially located in the front end of the second wire hole 54. The pickup 25 and the first transmission contact 30 are connected by a wire. The wire passes through the first wire hole 53 and the second wire hole 54 in sequence. The first transmission contact 30 is connected to the control module.

[0118] In this way, the bowel sound signal causes the vibrating diaphragm 24 to vibrate. This vibration is captured by the pickup element 25 and converted into an electrical signal. The captured electrical signal is then sent to the control module via the first transmission contact 30 and the aforementioned second transmission contact 41, thereby realizing the rapid acquisition, storage and processing of the bowel sound signal. Moreover, the structure of the entire pickup assembly 14 is relatively compact.

[0119] The second elastic element 27 can be configured as an elastic tube or a spring, as described above, and this application does not limit it in this regard.

[0120] The two plugs 29 mentioned above can be located on the front end face of the connector 28. The connector 28 is inserted into the two slots 42 of the moving component 17 through the two plugs 29. There are several first transmission contacts 30, which can be long strips.

[0121] The microphone assembly 14 can be a reusable consumable after cleaning and disinfection. When in use, press the microphone assembly 14 so that it is installed into the second mounting base 40 through the plug 29, and transmit signals and electrical energy through several first transmission contacts 30 and second transmission contacts 41.

[0122] Please refer to this as well. Figure 16 , Figure 16 This is a schematic diagram of the bowel sound monitoring device provided in an embodiment of the present invention after the air bladder is inflated, viewed from another angle.

[0123] In the embodiments provided in this application, please refer to Figure 4 and Figure 6 The mounting bracket 4 is equipped with an airbag 6, and the control panel 10 has a support member 15 on its rear side. The airbag 6 surrounds the mounting hole 44, and the support member 15 surrounds the microphone assembly 14. The support member 15 extends at least partially rearward beyond the mounting hole 44, and the microphone assembly 14 extends at least partially rearward beyond the support member 15. The mounting bracket 4 has an air inlet 7 on its front side, and the control panel 10 has an air pump (not shown) inside and an air outlet 13 on its rear side. The air pump is connected to the airbag 6 via the air outlet 13, the air inlet 7, and the control module. The airbag 6 is configured such that, after being inflated, its rear side is at least partially flush with the rear end face of the microphone assembly 14. The support member 15 is made of noise-reducing material.

[0124] When the control panel 10 is installed on the front side of the mounting bracket 4, the air inlet 7 can be inserted into the air outlet 13 to achieve rapid airflow connection. The control module can control the air pump to inflate the airbag 6 sequentially through the air outlet 13 and the air inlet 7. After inflation, the airbag 6 expands, and the inflated airbag 6... Figure 16 The airbag 6 is flush with the rear end face of the pickup component 14, so that the airbag 6 can fit tightly against the patient's skin and form a double-layer physical noise reduction barrier with the inner support 15. This can effectively shield noise from the external environment, reduce the impact of these noises on the acquisition process of the pickup component 14, and further improve the accuracy of bowel sound monitoring.

[0125] Specifically, the structure of support member 15 is not limited. For example... Figure 16 As shown, the support member 15 can be a rectangular frame. When two or more microphone components 14 are set, the support member 15 can be a rectangular grid, which can be set around the circumference of each microphone component 14 to enhance the noise reduction effect.

[0126] Each pickup component 14 is installed into the corresponding square on the support 15 via the corresponding movable component 17. The first mounting plate 32 of the movable component 17 can be directly fixed to the rear side wall of the control panel 10 or directly fixed to the inner side wall of the support 15. This application does not limit this.

[0127] The mounting hole 44 of the fixture 4 can be correspondingly set as a rectangle, and the support member 15 can pass through the mounting hole 44. Specifically, the airbag 6 can partially surround the outer peripheral wall of the fixture 4 and extend to the rear side wall of the fixture 4. In this way, the airbag 6 is located on the outer periphery of the support member 15, and can also be rectangular after inflation. The rear side of the inflated airbag 6 can be located on the rear side of the support member 15, so that the support member 15 does not come into contact with the patient, that is, the entire control component does not come into contact with the patient, and subsequent wiping disinfection can achieve thorough disinfection. Of course, the rear side of the inflated airbag 6 can also be flush with the rear side of the support member 15, and there is no specific limitation.

[0128] The specific noise reduction material used in the fabrication of the support component 15 is not limited; for example, it can be sound-absorbing cotton or foam plastic.

[0129] In the embodiments provided in this application, such as Figure 3 As shown, the waist belt 1 includes two elastic clamping straps 3. The two elastic clamping straps 3 are fixed to the left and right sides of the fixing frame 4 respectively and are respectively bent into arc shapes to the left and right sides, and there is a gap between the ends of the two elastic clamping straps 3.

[0130] Compared to related technologies where the waistband of a bowel sound monitoring device is connected to both sides by adhesive components, requiring the device to wrap around the patient's abdomen during installation and necessitating the patient to turn over, making the operation inconvenient, the bowel sound monitoring device provided in the above embodiments of this application features an open structure with arc-shaped elastic clamping straps 3 on both sides of the waistband 1. When installed on the patient's abdomen, the elastic clamping straps 3 can be bent outwards according to the patient's body shape, causing them to elastically deform. Then, the elastic clamping straps 3 can be released to restore their deformation and clamp the patient's waist and abdomen. This allows for quick installation of the bowel sound monitoring device on the patient's abdomen without requiring the patient to turn over, making it suitable for patients of different body types, more convenient to operate, and improving the installation efficiency of the bowel sound monitoring device.

[0131] In the embodiments provided in this application, the control component 2 further includes a human-computer interaction module. The human-computer interaction module is located on the control panel 10, and the control module and the human-computer interaction module are connected. The human-computer interaction module is used to receive the user's bowel sound collection command and send the bowel sound collection command to the control module; the control module is used to control the pickup component 14 to start after receiving the bowel sound collection command; the pickup component 14 is used to collect bowel sound signals and send the collected bowel sound signals to the control module; the control module is used to store and process the bowel sound signals and send the processed bowel sound signals to the human-computer interaction module; the human-computer interaction module is used to play or display the received bowel sound signals. Thus, the human-computer interaction module, the control module, and the pickup component 14 cooperate to achieve rapid collection, storage, processing, playback, or display of bowel sound signals.

[0132] In this embodiment, the bowel sound monitoring device further includes a wireless earpiece, and the control component 2 further includes a wireless communication module. The control module is connected to the wireless earpiece via the wireless communication module. Thus, the control module can transmit the stored bowel sound signals to the wireless earpiece via the wireless communication module, for example, to a Bluetooth earpiece, enabling remote auscultation. This not only allows for the selection of a quiet area for auscultation, avoiding the influence of external noise and improving diagnostic accuracy, but also eliminates the need for contact with patients during infectious disease outbreaks, preventing healthcare worker infections, and supports simultaneous auscultation by multiple individuals.

[0133] In this embodiment, the control component 2 may further include a power module, which may be located inside the control panel 10. The power module is used to supply power to the human-computer interaction module, the control module, the wireless communication module, the microphone component 14, the first motor 31, the second motor 36 and the air pump.

[0134] The human-computer interaction module may specifically include a display screen 11, several buttons 12, and a speaker. The display screen 11 and buttons 12 may be located on the front side of the control panel 10, and the speaker may be located inside the control panel 10. Users send corresponding control commands to the control panel 10 by pressing each button 12. These control commands, in addition to the aforementioned bowel sound acquisition commands, may also include start and stop commands for the bowel sound monitoring device, movement commands for the pickup component 14, and inflation commands for the airbag 6. Upon receiving these commands, the control panel 10 can control the start and stop of the bowel sound monitoring device, the pickup component 14 to acquire bowel sound signals, the activation of the first motor 31 and the second motor 36 of the moving component 17 to adjust the position of the pickup component 14, and the activation of the air pump to inflate the airbag 6.

[0135] The display screen 11 can be used to display bowel sound signals, and the speaker can be used to play bowel sound signals. The above instructions can be generated by pressing the corresponding button, or the display screen 11 can be set as a touch screen and generated by touching the touch screen. For example, the position of each pickup component 14 can be accurately displayed and the position of each pickup component 14 can be accurately adjusted.

[0136] The working principle of the bowel sound monitoring device provided in the embodiments of the present invention will be described below with reference to the accompanying drawings:

[0137] During assembly, the number and location of the pickup components 14 to be installed can be determined according to the location to be monitored. Then, the plug 29 of the pickup component 14 is connected to the slot 42 of the second mounting base 40 on the rear side of the control component 2 to complete the quick assembly of the pickup component 14 and the control component 2. Next, the control panel 10 and the mounting bracket 4 are aligned, and the two release blocks 18 are respectively inserted into the two release holes 9 of the control panel 10. Each buckle 16 enters the corresponding insertion hole 8. The control panel 10 is pressed towards the mounting bracket 4, and each buckle 16 presses against the locking end of the locking pin 20 inside the corresponding insertion hole 8, pushing the locking pin 20 to move away from the insertion hole 8. The locking pin 20 drives the release block 18 to move backward via the connecting rod 21, and the first elastic element 19 is deformed by pressure. As the buckle 16 continues to move within the insertion hole 8, the engaging end of the insertion hole 8 gradually aligns with the engaging hole 43 of the buckle 16. Under the elastic force of the first elastic element 19, the release block 18 moves forward and, via the connecting rod 21, drives the locking pin 20 to move closer to the insertion hole 8 until the locking pin 20 engages with the engaging hole 43, thus locking and limiting the buckle 16 and achieving rapid assembly of the control component 2 and the belt 1. The entire assembly process is extremely convenient and can improve the assembly efficiency of the bowel sound monitoring device.

[0138] During installation, the two elastic clamping straps 3 can be adjusted according to the patient's body shape, securing them to the left and right sides of the patient's waist and abdomen respectively. Releasing the straps allows them to clamp the patient's waist and abdomen, enabling rapid installation of the bowel sound monitoring device. The entire process requires no patient intervention and is extremely convenient. After installation, the control component 2 and the pickup component 14 are located in front of the patient.

[0139] In use, the air pump is activated via button 12 on the control panel 10, inflating the airbag 6 on the waist belt 1. The inflated airbag 6 contacts the patient's skin, forming a double-layer physical noise reduction barrier with the support member 15 on the control component 2, ensuring the acquisition accuracy of the sound pickup component 14. Button 12 controls each sound pickup component 14 to begin acquiring bowel sound signals. The sound pickup component 14 transmits the acquired bowel sound signals to the control module, which stores and processes the bowel sound signals, enabling continuous long-term monitoring of bowel sounds.

[0140] By controlling the start and stop of each first motor 31 and each second motor 36 via the button 12 on the control panel 10, the position of each pickup component 14 can be adjusted. This not only ensures that each pickup component 14 is in the correct monitoring position, improving the accuracy of bowel sound signal monitoring, but also allows each pickup component 14 to collect bowel sound signals at all positions within the set area, achieving comprehensive collection of bowel sound signals and improving the completeness of bowel sound signal collection.

[0141] The control module transmits bowel sound signals to the display screen 11, which shows the signal waveform to assist doctors in observation and judgment, facilitating further processing. The control module can also transmit the bowel sound signals to a speaker for playback during on-site auscultation. If there is significant ambient noise, or during epidemic prevention and control measures, the bowel sound signals can be transmitted via a wireless communication module to wireless headphones for remote auscultation, thus isolating noise or preventing infection among medical staff.

[0142] During installation, the microphone assembly 14 is pressed against the patient's abdomen, compressing its second elastic element 27. This ensures that the microphone assembly 14 remains in close contact with the patient's skin. The second elastic element 27 also undergoes slight deflection due to the suspended design of the microphone module 22 relative to the connecting seat 28, ensuring that the microphone assembly 14 is suitable for the curvature of different positions on the patient's abdominal surface, thereby guaranteeing the accuracy of bowel sound acquisition. During use, when the patient's breathing causes abdominal rise and fall, the second elastic element 27 also adaptively deflects to adjust the posture of the microphone module 22, ensuring that the microphone module 22 always adapts to the curvature of the patient's abdomen.

[0143] After completing bowel sound monitoring for one patient, pry open the two elastic clamping straps 3 outwards to quickly remove the bowel sound monitoring device from the patient. Then, press the two release blocks 18. The release blocks 18 drive the connecting rods 21 to rotate. One end of the connecting rod 21 moves backward, and the other end drives the corresponding locking pin 20 to move along the moving channel 48 away from the insertion hole 8 until the locking pin 20 disengages from the locking hole 43 of the buckle 16. The first elastic element 19 is compressed. At this time, the control component 2 can be removed from the belt 1. Release the release blocks 18. Under the elastic force of the first elastic element 19, the release blocks 18, connecting rods 21, and locking pins 20 reset. The locking pins 20 are inserted into the corresponding insertion holes 8 for the assembly of the control component 2.

[0144] The microphone assembly 14 can be removed from the control assembly 2. The control assembly 2, which has little or no contact with the human body, can be wiped and disinfected. The belt 1 and microphone assembly 14, which have close contact with the human body, can be cleaned and disinfected separately according to the characteristics of each part, thereby improving the cleaning and disinfection effect, reducing the risk of cross-infection, and ensuring the safety of bowel sound monitoring.

[0145] When the bowel sound monitoring device is found to be partially damaged, such as reduced elasticity of the belt 1 or damage to the microphone assembly 14, that part can be discarded directly, while the more expensive control assembly 2 can be retained for reuse, thus reducing the cost of bowel sound monitoring. In field environments, the belt 1 or microphone assembly 14 can also be discarded as disposable consumables, which is convenient and quick.

[0146] After cleaning and disinfection, the assembly of each part or the reassembly of each part after replacing the damaged part can be quickly achieved through the snap-fit ​​structure between the above-mentioned pickup component 14 and control component 2, and the quick-connect mechanism 5 between control component 2 and belt 1.

[0147] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the device and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
