Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent stethoscope for infants. Background Art

[0002] As a medical device that combines the functions of a traditional stethoscope with digital technology, the smart stethoscope can collect heart and lung sound signals through highly sensitive sensors and use digital signal processing technology to reduce noise, enhance, and analyze the audio, assisting medical staff in quickly identifying abnormal physiological characteristics (such as heart murmurs and abnormal breath sounds). Its core purpose is to improve auscultation accuracy and reduce the risk of human misjudgment. It also supports data storage and remote transmission, facilitating case review and multidisciplinary consultation. In the field of pediatrics, because young children have small heart and lung structures and weak physiological signals, the use of smart stethoscopes for auscultation of young children is particularly important.

[0003] When used on young children, existing smart stethoscopes are usually fixed by simple adsorption or manual pressing. During the auscultation process, if the child moves, the stethoscope cannot autonomously track the area of the child being auscultated. Due to the child's limb swinging or body position changes, the stethoscope is easily offset from the target area, which leads to signal acquisition interruption or distortion, and ultimately reduces the accuracy of the algorithm analysis.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] Example 1: A smart stethoscope for children, such as Figures 1-4 As shown, it includes an intelligent module 1, which is provided with a wireless transmission module, an ear piece 101 is provided on one side of the intelligent module 1, and the intelligent module 1 is connected to the ear piece 101 through a hose; a fixing part 2 is fixedly connected to the side of the intelligent module 1 away from the hose thereon; a flexible ring 3 is fixedly connected to the side of the fixing part 2 away from the intelligent module 1, and the flexible ring 3 has a sound insulation function; a fixing block 4 is fixedly connected to the side of the flexible ring 3 away from the fixing part 2, and the fixing block 4 is provided with a pickup head 102, and the pickup head 102 is connected to the intelligent module 1 through a hose.

[0022] In the above scheme, the earpiece 101 is an existing device, which is composed of symmetrically distributed earplugs, symmetrically distributed earrings, spring sheets, symmetrically distributed short rubber hoses and T-tubes. The specific arrangement thereof will not be described in detail; the smart module 1 is connected to an electronic device (such as a mobile phone, computer, etc.) through the wireless transmission module thereon; the outer diameter of the flexible ring 3 is equal to the diameter of the fixing member 2, and the specific material of the flexible ring 3 can be selected according to the specific usage requirements during production. The flexible ring 3 is used to enable relative movement between the fixing member 2 and the fixing block 4; in this embodiment, the pickup head 102 is fixed to the rear side of the fixing block 4 by a connecting rod.

[0023] like Figure 4 and Figure 5 As shown, it also includes: a limiting ring 5, which is fixed to the side of the fixing member 2 close to the fixing block 4, and the limiting ring 5 is located in the flexible ring 3; a moving rod 6, which is slidingly connected to the limiting ring 5, and the moving rod 6 is fixed to the fixing block 4.

[0024] In the above scheme, the limiting ring 5 is located on the rear side of the fixing part 2; the moving rod 6 is located on the front side of the fixing block 4, and a sound-absorbing treatment is performed between the limiting ring 5 and the moving rod 6 to reduce the impact of the noise generated by the movement of the two on the auscultation process.

[0025] like Figure 5 As shown, the moving rod 6 is composed of a cylinder and a disc, and the diameter of the cylinder is smaller than the diameter of the disc. The minimum diameter of the limiting ring 5 is larger than the diameter of the cylinder of the moving rod 6 but smaller than the diameter of the disc of the moving rod 6. It is used to limit the moving range and moving direction of the moving rod 6, thereby limiting the deformation degree of the flexible ring 3.

[0026] like Figure 2-Figure 4As shown, the fixing member 2 and the fixing block 4 are jointly provided with a blocking ring 7. Initially, the blocking ring 7 connects the fixing member 2 and the fixing block 4 so that the two cannot move relative to each other, and the connection method between the blocking ring 7 and the two can be specifically selected according to the use requirements during production, such as threaded connection and the like.

[0027] The specific workflow of the above solution is as follows: When it is necessary to use this device to perform auscultation on a young child, the medical staff wears the device according to the operating specifications and connects the wireless transmission module on the smart module 1 to the electronic device. The medical staff then moves the shielding ring 7 backward, causing the shielding ring 7 to lose contact with the fixing part 2 and the flexible ring 3 in turn, until the shielding ring 7 moves backward to the extreme position. At this time, the shielding ring 7 loses contact with the flexible ring 3 (and the front side of the shielding ring 7 is flush with the front side of the fixing block 4), that is, the fixing block 4 and the fixing part 2 can produce relative movement.

[0028] After the shielding ring 7 moves to the extreme position, the medical staff activates the intelligent module 1 and performs auscultation on the child according to the operating specifications (the sound is transmitted from the pickup head 102 to the intelligent module 1 through the hose, and then from the intelligent module 1 to the earpiece 101 through the hose). At the same time, the wireless transmission module transmits the auscultation results to the electronic device so that the medical staff can record the auscultation results. During the auscultation process (the pickup head 102 must be close to the child's clothes, and there must be appropriate pressure between the pickup head 102 and the child to ensure appropriate friction between the child and the pickup head 102), if the child moves, the following description takes the child moving to the left as an example: During the movement of the child, the pickup head 102 is driven to move synchronously to the left by friction, and the pickup head 102 drives the fixed block 4 to move to the left, and the fixed block 4 drives the moving rod 6 to move synchronously to the left along the limiting ring 5, and the fixed block 4 drives the flexible ring 3 to move synchronously, causing the flexible ring 3 to deform. At the same time, the flexible ring 3 absorbs the noise generated by friction when the limiting ring 5 and the moving rod 6 move relative to each other, reducing the impact on the auscultation results, so that the pickup head 102 can move with the movement of the child, thereby maintaining the stability of the position between the pickup head 102 and the child, and improving the accuracy of the sound positioning of the auscultation part by the pickup head 102.

[0029] After the auscultation is completed, the staff turns off the intelligent module 1, then separates the pickup head 102 from the child, and manually resets the fixed block 4 to the initial position relative to the fixing part 2. At the same time, the fixed block 4 drives the moving rod 6 to move synchronously. After the fixed block 4 is reset, the medical staff resets the shielding ring 7 to the initial position, so that the shielding ring 7 reconnects the fixing part 2 and the fixed block 4 for subsequent use.

[0030] Example 2: Based on Example 1, Figure 3 、 Figure 4 and Figure 7 As shown, it also includes: a connecting column 8, which is fixed to the side of the pickup head 102 close to the fixing part 2, and the shielding ring 7 is slidably connected to the fixing part 2 and the fixing block 4; a connecting shell 9, which is arranged on the side of the fixing block 4 away from the moving rod 6, and the connecting shell 9 is slidably connected to the shielding ring 7, and the connecting shell 9 is slidably connected to the connecting column 8, and a tension spring is fixed between the shielding ring 7 and the pickup head 102; an elastic airbag 10, which is fixed in the connecting shell 9, and the connecting column 8 is in contact with the elastic airbag 10.

[0031] In the above scheme, the connecting column 8 is composed of two sections of cylinders with different diameters, of which the cylinder with a larger diameter is located on the rear side, and the cylinder with a smaller diameter on the connecting column 8 slides in the connecting shell 9; the diameter of the connecting shell 9 is equal to the inner diameter of the shielding ring 7, so that the shielding ring 7 can move along the connecting shell 9; the connecting shell 9 is located on the rear side of the fixed block 4, and in this embodiment, the connecting shell 9 is fixed to the fixed block 4; the elastic airbag 10 can be deformed under the action of pressure, and initially the connecting column 8 is in contact with the elastic airbag 10, and initially the elastic airbag 10 does not have any elastic force; initially, the tension spring between the shielding ring 7 and the pickup head 102 is in a stretched state.

[0032] like Figure 4 、 Figure 7 and Figure 8 As shown, it also includes: an extrusion block 11, a guide rod is fixedly connected to the connecting shell 9, the extrusion block 11 is slidably connected to the guide rod in the connecting shell 9, and a first spring is fixedly connected between the extrusion block 11 and the connecting shell 9; a limit block 12 is slidably connected to the blocking ring 7, a second spring is fixedly connected between the limit block 12 and the blocking ring 7, the connecting shell 9 is used to limit the limit block 12, and the extrusion block 11 is used to change the position of the limit block 12; a moving block 13 is rotatably connected to the side of the extrusion block 11 close to the connecting column 8, the connecting shell 9 is provided with a limiting groove 14, the moving block 13 slides in the limiting groove 14, and the connecting column 8 is used to extrude the moving block 13.

[0033] In the above scheme, initially, the extrusion block 11 is at the lowest side under the action of the first spring; a through hole is provided at the front of the upper side of the connecting shell 9, and the limit block 12 is located in the through hole on the front side of the connecting shell 9. Initially, the limit block 12 is at the lowest side under the action of the second spring thereon, and initially, the extrusion block 11 is in contact with the limit block 12; the limit groove 14 is a horizontal straight groove.

[0034] The specific workflow of the above solution is as follows: When it is necessary to use this device to auscultate a child, the medical staff first connects the electronic device to the wireless transmission module on the smart module 1 and wears the earpiece 101 according to the operating specifications. Then the medical staff places the pickup head 102 on the child and presses the smart module 1, so that the smart module 1 drives the limiting ring 5 and the moving rod 6 to move backward through the fixing member 2, and the moving rod 6 drives the fixing block 4 to move backward, and the fixing block 4 drives the connecting shell 9 to move backward, and the connecting shell 9 drives the shielding ring 7 to move backward through the limiting block 12. At the same time, in this process, the pickup head 102 is blocked by the child and cannot move backward, so that the connecting shell 9 moves backward relative to the connecting column 8, and the elastic airbag 10 inside it is driven by the connecting shell 9 to move backward synchronously during the movement, so that the elastic airbag 10 is squeezed and deformed by the connecting column 8, and the elastic airbag 10 accumulates force.

[0035] During the backward movement of the connecting shell 9, the connecting shell 9 drives the moving block 13 to move backward synchronously through the extrusion block 11. After the connecting column 8 contacts the moving block 13, during the continuous movement of the connecting shell 9, the connecting column 8 squeezes the moving block 13, causing the lower part of the moving block 13 to move upward, and the extrusion block 11 is driven to move upward by the moving block 13. During the movement, the extrusion block 11 squeezes the first spring thereon, causing the first spring to compress and accumulate force. At the same time, during the upward movement of the lower part of the moving block 13, the rear part of the moving block 13 moves backward along the limiting groove 14 (thereby converting the moving block 13 from an inclined state to a horizontal state).

[0036] During the upward movement of the extrusion block 11, the extrusion block 11 squeezes the limit block 12, causing the limit block 12 to move upward, and the limit block 12 squeezes the second spring thereon during the upward movement, causing the second spring to compress and accumulate force, thereby reducing the contact area between the limit block 12 and the connecting shell 9. When the extrusion block 11 moves upward to the limit position, the limit block 12 moves upward to the outside of the through hole of the connecting shell 9, that is, the limit block 12 no longer limits the connecting shell 9. At this time, the tension spring on the pickup head 102 drives the shielding ring 7 to move backward, causing the shielding ring 7 to gradually lose contact with the fixing member 2 and the fixing block 4.

[0037] After the tension spring on the sound pickup head 102 returns to its unstretched state (at this time the connecting post 8 can still move relative to the connecting shell 9 in the front-to-back direction), the shielding ring 7 loses contact with the fixing part 2 and the fixing block 4. The medical staff then performs auscultation on the child according to the above operation. At the same time, during the auscultation process, when the child moves backward, the squeezing force between the child and the sound pickup head 102 will be relatively weakened. At this time, the elastic airbag 10 changes to its initial state, and the elastic airbag 10 pushes the connecting post 8 to move backward along the connecting shell 9, thereby driving the sound pickup head 102 to move synchronously by the connecting post 8, maintaining the fit between the sound pickup head 102 and the child; when the child moves forward, the child squeezes the sound pickup head 102, causing the sound pickup head 102 to drive the connecting post 8 to move forward relative to the connecting shell 9, and the connecting post 8 squeezes the elastic airbag 10 again during the movement, causing the elastic airbag 10 to continue to be compressed and accumulate force, thereby reducing the resistance of the sound pickup head 102 to the child.

[0038] After the auscultation is completed, the medical staff separates the sound pickup head 102 from the child. After the sound pickup head 102 is separated from the child, the elastic airbag 10 is no longer subjected to the squeezing force, so that the elastic airbag 10 drives the connecting column 8 to move backward relative to the connecting shell 9, so that the connecting column 8 is reset relative to the connecting shell 9. In this process, as the connecting column 8 gradually moves, the squeezing force of the connecting column 8 on the moving block 13 gradually decreases, so that the squeezing block 11 gradually moves downward under the action of the first spring thereon, and the moving block 13 is driven to move synchronously by the squeezing block 11. After the connecting column 8 loses contact with the moving block 13, the first spring on the squeezing block 11 drives the squeezing block 11 to move downward to the initial position relative to the connecting shell 9, and then the medical staff moves the shielding ring 7 forward (to reset the shielding ring 7 relative to the fixed block 4), so that the shielding ring 7 stretches the tension spring on it and accumulates force during the forward movement.

[0039] During the movement of the blocking ring 7, the blocking ring 7 drives the limit block 12 to move synchronously (the second spring on the limit block 12 is always in a compressed state during this process). After the blocking ring 7 is reset to its initial position relative to the fixed block 4, the limit block 12 is aligned with the through hole on the connecting shell 9. Then the limit block 12 is reset downward under the action of the second spring thereon, so that the limit block 12 re-enters the through hole on the connecting shell 9. The limit block 12 and the through hole on the connecting shell 9 jointly limit the blocking ring 7 for subsequent use.

[0040] Example 3: Based on Example 2, Figure 4-Figure 6As shown, it also includes: a first connecting seat 15, which is fixed to the side of the fixed block 4 close to the connecting shell 9; a first connecting rod 16, which is fixed to the side of the connecting shell 9 close to the fixed block 4, and the first connecting rod 16 and the first connecting seat 15 are ball-connected, and a plurality of third springs are fixed to the side of the fixed block 4 close to the connecting shell 9, and the third spring on the fixed block 4 is fixed to the second connecting seat 17, and the second connecting seat 17 is ball-connected with the second connecting rod 18, and the second connecting rod 18 is fixed to the side of the connecting shell 9 close to the extrusion plate 19, and the extrusion plate 19 is in contact with the connecting shell 9.

[0041] In the above scheme, the specific number of the third springs on the fixed block 4 is selected according to the specific production requirements during production. A number of third springs can be controlled to be evenly distributed circumferentially on the fixed block 4 so that the connecting shell 9 is evenly stressed. Initially, the third springs on the fixed block 4 are all in a stored force state. The third springs evenly distributed circumferentially on the fixed block 4 maintain the connecting shell 9 in a horizontal state (so that the front side of the connecting shell 9 is parallel to the fixed block 4); the extrusion plate 19 is squeezed by the connecting shell 9 and always fits with the front side of the connecting shell 9.

[0042] The specific workflow of the above solution is as follows: During the process of auscultation of a child, when the child leans forward, the child squeezes the sound pickup head 102, causing the sound pickup head 102 to move forward. At the same time, the child will also lean relative to the sound pickup head 102. At this time, the child's squeezing force on the upper side of the sound pickup head 102 increases, and the squeezing force on the lower side of the sound pickup head 102 decreases, thereby causing the sound pickup head 102 to drive the first connecting rod 16 to rotate upward relative to the first connecting seat 15 through the connecting shell 9, even if the connecting shell 9 is tilted upward relative to the fixed block 4.

[0043] During the tilting process of the connecting shell 9, the connecting shell 9 squeezes the upper squeezing plate 19, so that the squeezing plate 19 is subjected to the squeezing force and drives the second connecting rod 18 to rotate relative to the second connecting seat 17, and at the same time, the third spring on the upper side of the fixed block 4 is compressed again to store force. During this process, the squeezing force exerted on the third spring on the lower side of the fixed block 4 gradually decreases, so that the third spring on the lower side of the fixed block 4 drives the second connecting seat 17 on the lower side to move backward. At the same time, under the action of the lower third spring, the lower squeezing plate 19 is always kept in contact with the front side of the squeezing plate 19 (the second connecting rod 18 on the lower side rotates relative to the second connecting seat 17 on the lower side). At the same time, during this process, the two squeezing plates 19 in the middle are driven by the connecting shell 9 to tilt synchronously, so that the two squeezing plates 19 in the middle respectively drive the adjacent second connecting rods 18 to rotate relative to the adjacent second connecting seats 17, thereby keeping the contact area of the pickup head 102 with the child stable during the tilting process of the child.

[0044] After the auscultation contact, the staff separates the sound pickup head 102 from the child. After the sound pickup head 102 is separated from the child, the sound pickup head 102 is no longer subjected to the squeezing force, and the connecting shell 9 is no longer subjected to the squeezing force. Subsequently, under the joint action of the third spring uniformly distributed circumferentially on the fixed block 4, the connecting shell 9 is reset to the initial position relative to the fixed block 4 (during the movement of the connecting shell 9, the movement process parameters of the four squeezing plates 19 and other parts connected thereto are as described above, wherein the movement process of the lower squeezing plate 19 is similar to the movement process of the above-mentioned upper squeezing plate 19, and the movement process of the upper squeezing plate 19 is similar to the movement process of the above-mentioned lower squeezing plate 19. When the connecting shell 9 is reset to the initial position relative to the fixed block 4, the four squeezing plates 19 are synchronously reset to the initial position relative to the fixed block 4), and the shielding ring 7 is reset to the initial position relative to the connecting shell 9 according to the above-mentioned operation for subsequent use.

[0045] During the auscultation of the child, when the child leans backward or left or right, the specific working process of the fixed block 4 and other parts connected thereto can refer to the movement process of the fixed block 4 when the child leans forward.

[0046] like Figure 6 As shown, it also includes: a friction ring 20, which is fixed to the side of the first connecting seat 15 away from the fixed block 4, and the friction ring 20 is in contact with the first connecting rod 16. The friction ring 20 is made of an elastic deformable material and is used to increase the friction between the first connecting rod 16 and the first connecting seat 15, thereby increasing the stability of the position of the first connecting rod 16.

[0047] The specific workflow of the above solution is as follows: During the process of the first connecting rod 16 tilting upward relative to the first connecting seat 15, the first connecting rod 16 squeezes the upper side of the friction ring 20, causing the inner ring of the friction ring 20 to deform under the influence of friction, thereby increasing the friction force exerted on the first connecting rod 16 during movement (i.e., increasing the resistance of the first connecting rod 16 during movement). At the same time, after the first connecting rod 16 moves, the resistance of the first connecting rod 16 during the resetting process is increased (the first connecting rod 16 squeezes the lower side of the friction ring 20 during the resetting process), thereby maintaining the stability of the position of the first connecting rod 16 and the connecting shell 9 after movement.

[0048] like Figure 3 and Figure 4 As shown, a sound insulation ring 21 is fixed between the fixed block 4 and the connecting shell 9, and the sound insulation ring 21 is made of elastic deformable material. When the connecting shell 9 tilts relative to the fixed block 4, the connecting shell 9 drives the sound insulation ring 21 to deform, and the sound insulation ring 21 isolates the noise generated by the friction between the parts of the connecting shell 9 and the fixed block 4, thereby increasing the accuracy of the auscultation results.

[0049] While the disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised which do not depart from the scope of the invention.
