[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and features in different embodiments may be combined with each other.

[0036] In one aspect, an embodiment of the present invention provides a chest lead electrocardiogram detection device, comprising: a guide, a joint chain, and a chest lead ball.

[0037] Specifically, the guide includes at least two movably connected guides, which are used to deform according to the shape of the user's chest wall based on their own movement, and adapt to the user's chest wall of different sizes and shapes.

[0038] It can be understood that the above-mentioned setting can reduce the learning cost of medical staff or patients and reduce measurement errors by installing all the chest lead balls in sequence on the fixator before use. There is no need to consider the arrangement order of the chest lead balls during use, while avoiding the problem of wire entanglement in the adsorption process of the chest lead balls in the prior art, thereby improving the operating efficiency of the chest lead; the joint chain is driven by the guide to fit the user's chest wall, thereby avoiding the problem of unstable adsorption in the adsorption process of the chest lead balls in the prior art, thereby improving the operating efficiency of the chest lead; the position of each chest lead ball is fixed and the installation is stable through the joint chain and the fixator, thereby avoiding the problem of electric needle falling off and touching in the prior art, thereby improving the operating efficiency of the chest lead.

[0039] like Figure 1 As shown, in some embodiments, the guide member includes: a core plate 8, a first left wing plate 10 connected to the left side of the core plate 8, a first right wing plate 15 connected to the right side of the core plate 8, a second wing plate 17, a third wing plate 18 and a fourth wing plate 19 connected to the right side of the first right wing plate 15 in sequence. Specifically, the first left wing plate 10 and the first right wing plate 15 are respectively telescopically connected to the core plate 8, the second wing plate 17 is rotationally connected to the first right wing plate 15, the third wing plate 18 is rotationally connected to the second wing plate 17, and the fourth wing plate 19 is telescopically connected to the third wing plate 18. Among them, the fourth wing plate 19 can be embedded in the third wing plate 18 and telescopically move relative to the third wing plate 18.

[0040] In some embodiments, the fixator includes: a first fixator and a second fixator connected to the core board 8, and a third fixator, a fourth fixator, a fifth fixator and a sixth fixator connected to the first right wing board 15, the second wing board 17, the third wing board 18 and the fourth wing board 19 in sequence. Each fixator is connected to a chest lead ball, and the fixator can squeeze the spherical end of the chest lead ball so that the adsorption end of the chest lead ball is adsorbed on the chest wall of the user.

[0041] In some embodiments, the chest lead ball includes: a first chest lead ball 1, a second chest lead ball 2, a third chest lead ball 3, a fourth chest lead ball 4, a fifth chest lead ball 5 and a sixth chest lead ball 6 which are sequentially connected to a first fixture, a second fixture, a third fixture, a fourth fixture, a fifth fixture and a sixth fixture. The chest lead ball is used to collect the electrocardiogram signal of the user.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the chest lead electrocardiogram detection device also includes: an input component and an output component.

[0043] Specifically, the input component includes: a power supply, a switch 9 located on the core board 8, and a sensor module.

Among them, the laser ranging sensor is used to detect the distance between the wing board and the user's chest wall, the thin film pressure sensor 21 is used to detect the pressure between the adsorption end of the chest lead ball and the user's chest wall, and the two six-axis motion processing modules are used to detect the inclination angle between the core board 8 and the third wing board 18.

[0044] Specifically, the output component includes a drive module and a display screen. The drive module includes: six servos located in the holder and four servos located in the first right wing plate 15, the second wing plate 17, the third wing plate 18 and the fourth wing plate 19. The display screen can be located in the center of the core board 8, and the display screen can be a touch screen and is used to display parameter information and prompts of the guide automatic deformation.

[0045] It can be understood that the above-mentioned intelligent system design of the chest lead electrocardiogram detection device allows the shape of the guide to automatically conform to the deformation of the chest wall. After the deformation is completed, the operator only needs to press the manual switch 9, which greatly improves the detection efficiency of the chest leads.

[0046] like Figure 3As shown, in some embodiments, the joint chain includes: a first support rod 24, a second support rod 20 and a third support rod 25. Specifically, the first support rod 24 is located on the side of the first fixture away from the second fixture, and the first support rod 24 is connected to the first left wing plate 10.

A connecting rod 23 is located between the fifth fixer and the sixth fixer, and the fifth fixer and the sixth fixer are connected via the connecting rod 23. The above arrangement can achieve high degree of freedom of extension and retraction of the joint chain.

[0047] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, in some embodiments, the core board 8 includes: a handle 12, an upper shell 46 and a lower shell 51. Specifically, the handle 12 is connected to the upper shell 46, and the end of the handle 12 close to the upper shell 46 has a switch 9. The upper shell 46 has grooves 47 matching the clamping protrusions 53 of the first left wing plate 10 and the first right wing plate 15 on both sides, and the upper shell 46 is clamped with the first left wing plate 10 and the first right wing plate 15 respectively through the grooves 47 and the protrusions. The above-mentioned grooves 47 and protrusions can be L-shaped, so as to facilitate the clamping, so that the core board 8 is not easy to come out from the first left wing plate 10 and the first right wing plate 15. The upper shell 46 has a first laser ranging sensor 22 on one side close to the user's chest wall, which is used to detect the distance L1 between the core board 8 and the user's chest wall.

The lower shell 51 has a first gear 54, a second gear 55 and a third gear 56 that are meshed in sequence, and the third gear 56 is also meshed with the first rack 57 of the first left wing plate 10 and the second rack 58 of the first right wing plate 15 respectively, to respectively realize the sliding connection of the first left wing plate 10 and the first right wing plate 15 with the core board 8. The lower shell 51 has a fourth gear 60, and the fourth gear 60 can be a bevel gear to change the direction of the first steering gear 59. The lower shell 51 has a first six-axis motion processing module 52 to detect the motion state of the core board 8, i.e., yaw angle, pitch angle and roll angle, etc.

[0048] like Figure 1 , Figure 3 , Fig. 9 and Fig.10As shown, in some embodiments, the guide includes: three connection disks 61, three pan-tilt platforms 62, a second servo 68, a third servo 69, and a fourth servo 64. Specifically, the second servo 68 is connected to the side of the first right wing plate 15 close to the user's chest wall through the connection disk 61 and the pan-tilt platform 62, and the second servo 68 is also connected to the second wing plate 17 and drives the second wing plate 17 to rotate relative to the first right wing plate 15. The third servo 69 is connected to the side of the second wing plate 17 close to the user's chest wall through the connection disk 61 and the pan-tilt platform 62, and the third servo 69 is also connected to the third wing plate 18 and drives the third wing plate 18 to rotate relative to the second wing plate 17. The fourth servo 64 is connected to the side of the third wing plate 18 close to the user's chest wall through the connection disk 61 and the pan-tilt platform 62, and the fourth servo 64 is also connected to the fourth wing plate 19 and drives the fourth wing plate 19 to rotate relative to the third wing plate 18. The guide includes: a second laser ranging sensor 29 located at the first left wing plate 10, a third laser ranging sensor 28 located at the first right wing plate 15, a fourth laser ranging sensor 27 located at the second wing plate 17, and a fifth laser ranging sensor 30 located at the fourth wing plate 19. Among them, the second laser ranging sensor 29 is used to detect the distance L2 between the first left wing plate 10 and the user's chest wall, the third laser ranging sensor 28 is used to detect the distance L3 between the first right wing plate 15 and the user's chest wall, the fourth laser ranging sensor 27 is used to detect the distance L4 between the second wing plate 17 and the user's chest wall, and the fifth laser ranging sensor 30 is used to detect the distance L5 between the fourth wing plate 19 and the user's chest wall.

[0049] like Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments, the third wing plate 18 has a fifth gear 63, a sixth gear 65 and a seventh gear 66 that mesh with each other, and the sixth gear 65 is also meshed with the third rack 67 of the fourth wing plate 19 to achieve a sliding connection between the third wing plate 18 and the fourth wing plate 19. The seventh gear 66 is a double-layer gear, the small diameter of the seventh gear 66 is meshed with the fifth gear 63, and the large diameter of the seventh gear 66 is meshed with the sixth gear 65. Among them, the fifth gear 63 can be a bevel gear, and the above setting can change the direction of the fifth gear 63 and amplify the stroke. The third wing plate 18 has a second six-axis motion processing module 26. The second six-axis motion processing module 26 is used to detect the motion state of the third wing plate 18, that is, the yaw angle, pitch angle and roll angle.

[0050] like Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15As shown, in some embodiments, the fixator includes: a main body plate 38. The main body plate 38 has a strangle structure 33 formed by a central opening connected to the side of the main body plate 38, and the strangle structure 33 clamps the neck of the chest lead ball. The two sides of the neck of the chest lead ball are respectively connected to the spherical end and the adsorption end. The fixator includes: a first splint 31 and a second splint 32. The first splint 31 has a fourth rack 36, and the second splint 32 has a fifth rack 37. The main body plate 38 has two parallel sliding grooves for the fourth rack 36 and the fifth rack 37 to slide and drive the first splint 31 and the second splint 32 to move. The first splint 31 and the second splint 32 jointly squeeze the spherical end of the chest lead ball so that the adsorption end of the chest lead ball is adsorbed on the user's chest wall. The holder includes: an eighth gear 39, a ninth gear 40 and a tenth gear 41. The eighth gear 39 is meshed with the fourth rack 36, and the ninth gear 40 is meshed with the fifth rack 37 to ensure that the first clamping plate 31 and the second clamping plate 32 can be tightly matched and not easy to loosen, while not affecting the sliding, and ensure the synchronous movement of the two. The tenth gear 41 is meshed with the eleventh gear 35 of the fifth steering gear 34 to complete the rotation of the chest lead ball fixed to the fifth steering gear 34. The holder includes: a thin film pressure sensor 21. The thin film pressure sensor 21 is located on the side of the main plate 38 close to the user's chest wall, and is used to detect the pressure between the adsorption end of the chest lead ball and the user's chest wall.

[0051] Continue to refer Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15 In some embodiments, the fixer includes: a telescopic plate 44. The telescopic plate 44 is located in the slot of the main plate 38, and compression springs 43 are provided on both sides of the telescopic plate 44. The first end of the compression spring 43 abuts against the transverse protrusion 42 at one end of the telescopic plate 44, and the second end of the compression spring 43 abuts against the main plate 38, so that the telescopic plate 44 always has a tension to be retracted relative to the fixer, thereby making the entire joint chain have an inward tension. One end of the telescopic plate 44 has a limiting protrusion 45, which is clamped in the slot of the main plate 38 to prevent the telescopic plate 44 from falling out. The presence of the telescopic plate 44 on the fixer can make telescopic movements between the main plate 38 of the fixer, so the joint chain as a whole can be twisted and retracted. In addition, the above-mentioned design of the fixer makes close use of space, so that the chest lead electrocardiogram detection device can be miniaturized.

[0052] It is understandable that due to the traction and limitation of the joint chain by the guide and the inward tension of the joint chain, the chest lead ECG detection device can always be stably fixed on the user's chest wall unless the skin quality is so poor that no chest lead ball is successfully adsorbed.

[0053] Continue to refer Figure 1In some embodiments, the first left wing board 10 and the first right wing board 15 of the chest lead electrocardiogram detection device can be installed with four limb lead auxiliary brackets, and connected to the upper limb lead bracket slot 7 and the lower limb lead bracket slot 16. The limb lead auxiliary brackets can also integrate four limb leads on the device, further improving the automation of the device and improving the efficiency of electrocardiogram detection.

[0054] Continue to refer Figure 1 In some embodiments, the core board 8 of the chest lead ECG detection device can be connected to a robotic arm equipped with a depth camera, and a visual recognition algorithm can be used to move the chest lead ECG detection device in a three-dimensional space to further improve the degree of automation of the device and improve the efficiency of ECG detection.

[0055] It is understandable that, when using the chest lead electrocardiogram detection device, the operator only needs to touch the handle 12 and the display screen of the device throughout the whole process, which reduces health hazards. At the same time, the operator does not need to directly touch the chest of the female user, which can reduce medical disputes.

[0056] On the other hand, Fig.16 As shown, an embodiment of the present invention further provides a chest lead electrocardiogram detection method, using the above-mentioned chest lead electrocardiogram detection device, the method comprises:

[0057] S110, placing the chest lead electrocardiogram detection device on the chest wall of the user.

[0058] S120, the guide is deformed according to the shape of the user's chest wall;

[0059] S130, the fixator squeezes the spherical end of the chest lead ball, and the fixator rotates so that the adsorption end of the chest lead ball is adsorbed on the chest wall of the user;

[0060] S140. The chest lead ball collects electrocardiogram signals of the user's chest wall.

[0061] For the above step S110, specifically, for a user of any body type, after applying alcohol to a suitable position of the user's chest wall to increase skin conductivity, the operator grasps the handle 12 and places the chest lead electrocardiogram detection device at a position slightly below the midline of the user's chest wall. The user may be a patient who needs to undergo an electrocardiogram test, and the operator may be a medical staff member.

[0062] For the above step S120, specifically, a two-stage button switch 9 is provided at the front end of the handle 12. When lightly pressed, the first stage is started, and the guide begins to deform. The parameters that appear during the deformation and the prompt that the deformation is completed will be displayed on the screen.

[0063] For the above step S130, specifically, after the guide is deformed, the switch 9 is pressed to the bottom to start the second stage, and the button is released after the spherical ends of the six chest lead balls are squeezed, so that the six servos on the joint chain work and the chest lead balls are adsorbed.

[0064] For the above step S140, specifically, check the electrocardiogram waveform, make adjustments according to the log prompted by the screen, such as wiping with alcohol, etc., and wait for the electrocardiogram waveform to be recorded after the adjustment is completed.

[0065] In some embodiments, after the above step S140, the method may further include:

[0066] Press the switch 9 to the bottom again, and do not release it at this time. When the spherical end of the chest lead ball is squeezed and the chest lead electrocardiogram detection device can be removed from the user's chest wall, release the button. The above operation can reduce the pain of directly removing the chest lead ball from the user's chest wall and improve the user experience.

[0067] It is worth noting that the above S110 to S140 are merely step numbers, which are used to facilitate reference and avoid text duplication. Unless otherwise specified, the above and subsequent step numbers will not limit the order of implementation of the various steps of the method. In other embodiments, the above steps of the method can also be written and implemented in an interchangeable order, and are not limited thereto.

[0070] S121, pre-processing of retraction of the first left wing panel 10, the first right wing panel 15 and the second wing panel 17.

[0071] First, check whether the recorded values ​​of L1, L2 and L3 of the laser distance sensor are less than the set threshold. This threshold is the appropriate distance from the laser distance sensor on the guide to the surface of the user's chest wall skin under ideal conditions, such as 2cm (need to be adjusted according to specific circumstances), which should be greater than the minimum sensing distance of the distance measurement module.

[0072] At the same time, it is necessary to detect whether the recorded values ​​of the film pressure sensors 21P1, P2 and P6 are greater than a threshold value. The threshold value is a reasonable value set to simulate the pressure fed back to the fixator after a single chest lead ball contacts the skin.

[0073] Since the positions of the three detection laser ranging sensors just correspond to the first left wing plate 10, the first right wing plate 15 and the second wing plate 17, when the above-mentioned conditions of L1 < threshold value, L2 < threshold value and L3 < threshold value are not met, it means that the chest lead ECG detection device does not contact the user's chest wall, or contacts it but the value deviates due to asymmetry.

[0074] Since the positions of the three thin film pressure sensors 21 correspond exactly to the middle position of the first left wing plate 10 and the first right wing plate 15 and the end position of the fourth wing plate 19, when the above-mentioned conditions of P1>threshold, P2>threshold and P6>threshold are not met, it means that the chest lead ball in front of the guide has failed to contact the skin of the user's chest wall for some reason and needs to be checked. Especially when P6 does not reach the threshold, it often means that the user is small in size, because the S1 telescopic state is retained after the previous user has done it once, or the guide length is relatively long relative to the user's half chest wall, which causes the sixth chest lead ball 6 to be unable to contact the chest wall, so that the thin film pressure sensor 21 of the sixth chest lead ball 6 cannot feel the pressure.

[0075] When the above conditions are not met, the step length of S1 is retracted by 1 unit first, and then the above judgment is performed. This step length is set according to the actual situation, such as 0.5 cm.

[0076] When the above conditions are met, the preparatory form (the core board 8 of the chest lead electrocardiogram detection device is located at the center of the user's chest wall and is symmetrical on both sides, the left wing of the guide is in the most abducted state as a whole, the first chest lead ball 1, the second chest lead ball 2 and the sixth chest lead ball 6 have contacted the skin and generated pressure) is ready to proceed to the next step.

[0077] S122, the second wing plate 17 is folded inward.

[0078] If the judgment condition L4 < threshold value, P4 > threshold value is met, go to the next step directly; if not, close the joint R1 inward by 1 step, and repeat the judgment to make the second wing plate 17 and the fourth chest lead ball 4 fit the chest wall to contact the skin. If it is met, go to the next step.

[0079] S123, the third wing plate 18 is folded inward.

[0080] If the judgment conditions L5 < threshold value, P6 > threshold value are met, go to the next step directly; if not, close the joint R2 inward by 1 step, and repeat the judgment to make the fourth wing plate 19 and the sixth chest lead ball 6 fit the chest wall to contact the skin. If met, go to the next step.

[0081] S124, roll angle calibration.

[0082] Determine whether the rolling angle Φ* formed by M1 and M2 is less than the threshold value, which can be set to 90°-100°. When the judgment condition is met, it means that the deformation of the guide has met the condition. If it is not met, it means that the person's body shape is relatively large relative to the guide, and S1 needs to be stretched out to perform the above deformation process again until Φ* meets the condition. When performing this adjustment, S2 will stretch synchronously with S1, and its step length can be set additionally. The deformation of these two telescopic joints makes the guide larger as a whole. It should be noted that for rare users with barrel-shaped chests, the telescopic length of S2 can be set additionally through the display screen to adapt to their contours.

[0083] In some embodiments, after the above step S140, the method may further include:

[0084] The guide is partially reset and deformed, extending R1 and R2 to the limit position, while S2 retracts, and the entire guide is in a relatively "flat" state, completing the reset, and the next user's detection operation can be carried out.

[0085] It can be understood that the specific implementation method and technical effects of the chest lead electrocardiogram detection method can be found in the aforementioned chest lead electrocardiogram detection device, which will not be repeated here.

[0086] In summary, the chest lead electrocardiogram detection device and method of the present invention, by installing all the chest lead balls in sequence on the fixture before use, there is no need to consider the arrangement order of the chest lead balls during use, which can reduce the learning cost of medical staff or patients and reduce measurement errors, while avoiding the wire entanglement problem in the adsorption process of the chest lead balls in the prior art, thereby improving the operating efficiency of the chest lead; the joint chain is driven by the guide to fit the user's chest wall, thereby avoiding the adsorption instability problem in the adsorption process of the chest lead balls in the prior art, thereby improving the operating efficiency of the chest lead; the position of each chest lead ball is fixed and the installation is stable through the joint chain and the fixture, thereby avoiding the problem of electric needle falling off and touching in the prior art, thereby improving the operating efficiency of the chest lead.

[0087] The above contents are further detailed descriptions of the present invention in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
