Description

Electrocardiogram sensing assembly and electrocardiogram sensing device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an electrocardiograph sensing assembly and an electrocardiograph sensing device.

Background

Patient monitoring devices have been in development for over 30 years and include bedside monitoring devices, electrocardiographic telemetry devices, and transfer monitoring devices. With the development of micro-wound surgery, the wound of a patient is smaller and smaller, and the patient can get out of the bed to perform activities quickly after the operation. For example, after coronary intervention, the patient can get out of bed for phase I cardiac rehabilitation after several hours. The traditional bedside monitoring equipment needs bedside power supply support, one end of a sensor or a collector is connected to a host through a cable, and the other end of the sensor or the collector is connected to a patient, so that the patient can only lie on the bed, and the patient can monitor the patient with a messy cable, and the comfort level is poor.

On the other hand, along with the continuous improvement of living standard, people are also continuously improving the attention degree of self health, and then further demands are made on the portability of heart monitoring equipment, and the development of wearable technology enables people to transmit data in a wireless mode, and meanwhile, the wireless heart monitoring equipment has good comfort level and is gradually applied to hospitals and living.

The existing cardiac monitoring device comprises an electrocardiosignal used for being attached to a human body, and the electrocardiosignal comprises a plurality of electrodes, so that electrocardiosignals of different positions of the human body are acquired, and the more the number of the electrodes is, the more comprehensive the position distribution points are, the more the acquired electrocardiosignal data are, and the more accurate the monitoring result can be obtained.

As shown in fig. 1, a conventional electrocardiograph sensor includes a first portion 01 and a second portion 02 that are independent of each other, where the first portion 01 and the second portion 02 are connected by a flexible wire 03, and the first portion 01 and the second portion 02 are attached to different positions, for example, the first portion 01 is used for attaching to a position below a collarbone, and is used for obtaining an electrocardiograph signal independently or used in combination with the second portion 02 to obtain more electrocardiograph signals; the second part 02 is used for being attached to a position between fourth ribs or near other ribs so as to acquire different electrocardiosignals;

on the one hand, when a user needs to do movement or acts with a relatively large amplitude, the joint of the two parts of the electrocardio sensor attached to the body and the lead 03 is easy to pull, so that the signal accuracy is affected; on the other hand, since the length of the wire 03 between the two parts of the electrocardiograph sensor is fixed, the application area is narrow, after the two parts of the electrocardiograph sensor are attached to the human body, the wire 03 is too long, and the user experience and the monitoring effect can be affected because the user wears the foreign body feeling or the wire 03 is too short, so that the two parts of the electrocardiograph sensor cannot be attached to the correct positions.

The following description refers to the accompanying drawings.

Referring to fig. 2 and 3, an embodiment of the present utility model provides an electrocardiographic sensing assembly, which includes a first sensing unit 10, a second sensing unit 20, and a connection unit 30; the first sensing unit 10 is used for being laid at a first preset position of a target object; the second sensing unit 20 is used for being laid at a second preset position of the target object; the connection unit 30 is connected to the first sensing unit 10 and the second sensing unit 20, respectively; wherein the connection unit 30 limits an initial relative distance and/or an initial relative angle of the first sensing unit 10 and the second sensing unit 20 when in an initial state without an external force; the connection unit 30 is adapted to deform when the relative distance and/or relative angle of the first sensor unit 10 and the second sensor unit 20 changes.

The target object here may be a patient, or may be a prosthetic object such as a human model. Further, the first predetermined position may be, for example, a subclavian position of a human body (or a mannequin), and the second predetermined position may be, for example, a fourth intercostal and nearby position. The electrocardiographic sensing assembly can be used as an actual monitoring device when applied to a patient. When the electrocardio sensing component is applied to prosthesis objects such as a human body model, the electrocardio sensing component can provide a training operation environment or a calibration operation environment for an operator to train, and the utility model does not limit a target object. In particular, the application herein refers to that the first sensor unit 10, the second sensor unit 20, and the connection unit 30 are disposed on the target object in contact and contact relation with the target object. In some embodiments, it may be a paste (e.g., self-paste). In other embodiments, the device may be pressed by a certain external force or may be abutted against the target object under the limitation of an external limiting component (such as an adhesive tape), which is not limited in the utility model.

Referring to fig. 2 and 3, for convenience of description, a side of the electrocardiographic sensing element facing the target object is hereinafter referred to as a back side, and a side facing away from the target object is hereinafter referred to as a front side. Fig. 2 shows the front side of the electrocardiographic assembly, and fig. 3 shows the back side of the electrocardiographic assembly.

The initial state of the first sensor unit 10, the second sensor unit 20, and the connection unit 30 when no external force is applied thereto refers to the relative positional relationship between the first sensor unit 10, the second sensor unit 20, and the connection unit 30 when no external force is applied thereto, and the initial state may be regarded as a design form of the product. In this initial state, the connection unit 30 can limit the initial relative distance and/or the initial relative angle of the first and

second sensing units

10 and 20.

In an example of a usage scenario, after the first sensing unit 10 and the second sensing unit 20 are laid (e.g. pasted) at respective corresponding predetermined positions, the target object moves, so that the relative distance and/or relative angle between the first sensing unit 10 and the second sensing unit 20 varies within a certain range, and at this time, the connection unit 30 counteracts the change of the distance and/or angle between the first sensing unit 10 and the second sensing unit 20 by deforming itself, thereby allowing the change of the relative distance and/or relative angle between the first sensing unit 10 and the second sensing unit 20, effectively avoiding the pulling at the connection point between the first sensing unit 10 and the second sensing unit 20 and the connection unit 30, and improving the stability and accuracy of signal transmission.

In another example of a use scenario, during application of the electrocardiographic sensing assembly to the target object, the first sensing element 10 may first be attached to the target object at a location generally below the collarbone of the target object in a cross-sectional direction of the target object, the first predetermined location being relatively easy to determine. After the first sensor unit 10 is properly deployed, the user can find and locate a second predetermined position and then align the second sensor unit 20 to the second predetermined position. Because the positioning of the second predetermined position is affected by the different body types, the different heights, the different ages of people, and the different monitoring position requirements, the second predetermined position may be different in different application scenarios, so that the distance and/or angle of the second sensing unit 20 relative to the first sensing unit 10 are different, and when the second sensing unit 20 is aligned to the second predetermined position, a certain acting force is applied to the connecting unit 30, and the connecting unit 30 generates a certain deformation under the acting force to counteract the change of the distance and/or angle of the second sensing unit 20 relative to the first sensing unit 10, so that the second sensing unit 20 can be accurately laid to the second predetermined position. So configured, the relative distance and relative angle between the first sensing unit 10 and the second sensing unit 20 can be adjusted during installation, so that the electrocardiograph sensing assembly can be conveniently laid at a proper angle position, and the electrocardiograph sensing assembly can be suitable for more monitoring positions and different crowds, the accuracy of signal acquisition is improved, and the physical examination and monitoring effects of users are improved.

Optionally, the connection unit 30 includes a serpentine section extending in a zigzag reciprocation, and the serpentine section has flexibility to allow the connection unit 30 to be deformed in response to a change in a relative distance and/or a relative angle of the first sensing unit 10 and the second sensing unit 20. Since the serpentine section reciprocally extending in a zigzag shape has a curvature, the adjustment of the relative distance and the relative angle of the first sensing unit 10 and the second sensing unit 20 is more flexible, the serpentine section can be compressed when the first sensing unit 10 and the second sensing unit 20 are required to be disposed closer, and the serpentine section can be stretched when the first sensing unit 10 and the second sensing unit 20 are required to be disposed farther. So configured, the user's operation is more nimble, and same pattern electrocardio sensing assembly can be applicable to more different sizes, different heights, the crowd of different ages and the demand of different monitoring positions. Meanwhile, the serpentine section is not easy to break and fracture in any state, and the serpentine section cannot be pulled to the connection point of the first sensing unit 10, the second sensing unit 20 and the connection unit 30, so that the electrocardiosignal transmission is more stable.

Optionally, the first sensing unit 10 includes at least two first signal input parts 11, and at least two first signal input parts 11 are arranged along the extending direction of the first sensing unit 10; the second sensing unit 20 includes at least two second signal input parts 21, and at least two second signal input parts 21 are arranged along an extending direction of the second sensing unit 20. In the example shown in fig. 2 and 3, in the initial state, the extending direction of the first sensor unit 10 is parallel to the extending direction of the second sensor unit 20. Since the extending direction of the first sensing unit 10 and the extending direction of the second sensing unit 20 can be adjusted during the mounting to the target object, the extending direction of the first sensing unit 10 and the extending direction of the second sensing unit 20 can be configured to be parallel for simplicity of design and production.

In the example shown in fig. 2 and 3, the outer contour shape of the first sensor unit 10 is substantially elongated, and the extending direction of the first sensor unit 10 refers to the length direction thereof. The outer contour shape of the second sensing unit 20 is also substantially elongated, and the extending direction of the second sensing unit 20 is along the length direction thereof. As shown in fig. 2 and 3, in the initial state, the extending direction of the first sensing unit 10 is parallel to the extending direction of the second sensing unit 20.

In a certain monitoring state, the extension direction of the first sensor unit 10 is arranged along the cross-sectional direction of the target object. The extending direction of the first sensing unit 10 is a horizontal direction. The extending direction of the second sensing unit 20 extends from the fourth intercostal space of the right edge of the sternum to the left edge of the xiphoid process, the extending direction of the second sensing unit 20 is from the upper left to the lower right, the included angle between the extending direction and the horizontal direction is approximately 30-45 degrees, and at this time, a certain acting force is applied to the second sensing unit 20, so that the second sensing unit 20 overcomes the resistance of the connecting unit 30 to reach the target angle, and is laid on a corresponding second preset position. It will be appreciated that the connection unit 30 is now formed with a certain curvature.

The first signal input part 11 and the second signal input part 21 are used for acquiring different electrocardiographic signals from a target object, respectively. In an alternative exemplary embodiment, the first signal input 11 and/or the second signal input 21 comprise electrode contacts. Of course, in other embodiments, the first signal input unit 11 or the second signal input unit 21 may be configured to acquire an electrocardiographic signal of the target object, which is not limited to this aspect of the utility model.

At least two first signal inputs 11 are arranged along the extension direction of the first sensor unit 10, i.e. at least two first signal inputs 11 are arranged along the cross-sectional direction of the target object. Further, if the number of the first signal input portions 11 is plural, the plural first signal input portions 11 are preferably located at the same cross-sectional position. For example, in the example shown in fig. 2 and 3, the first sensing unit 10 includes 4 first signal inputs 11. It will be appreciated that in other embodiments, the first sensing unit 10 may also include 3 or more first signal input parts 11. In one monitoring state, at least one second signal input part 21 is positioned between fourth ribs of the right edge of the sternum, and at least another second signal input part 21 is positioned at the left edge of the xiphoid process. The connection lines of the two second signal input portions 21 are arranged along the extending direction of the second sensing unit 20. In the example shown in fig. 2 and 3, the second sensing unit 20 includes 2 second signal input parts 21. It will be appreciated that in other embodiments, the second sensing unit 20 may also include a greater number of second signal inputs 21.

Optionally, the first sensing unit 10 includes at least two first signal output parts 12 and at least two second signal output parts 13; at least two first signal output portions 12 are electrically connected to the corresponding first signal input portions 11, respectively; at least two of the second signal output portions 13 are electrically connected to the corresponding second signal input portions 21 through the connection unit 30.

The at least two first signal output portions 12 are electrically connected to the corresponding first signal input portions 11, respectively, which means that at least one signal output portion 12 is electrically connected to at least one corresponding first signal input portion 11, and that another signal output portion 12 is electrically connected to at least another corresponding first signal input portion 11. That is, the first signal output units 12 and the first signal input units 11 may be connected in one-to-one correspondence, that is, one-to-many correspondence, that is, the same first signal output unit 12 may be connected to two or more first signal input units 11. In the example shown in fig. 2 and 3, the first sensing unit 10 includes 4 first signal output parts 12 and includes 4 first signal input parts 11, the connection relationships of which are in one-to-one correspondence. In other embodiments, the number of the first signal input portions 11 and the first signal output portions 12 may be only 1, and the number of the signal output portions 12 and the second signal output portions 13 may correspond to the number of the first signal input portions 11 and the first signal output portions. Those skilled in the art can configure the number and the corresponding connection relation of the first signal output parts 12 and the first signal input parts 11 differently according to the above description, and the present utility model is not limited thereto.

The first signal output portion 12 and the second signal output portion 13 are configured to be electrically connected to corresponding structures of the host computer 40 (see fig. 7 and 8) to output the electrocardiographic signals acquired by the first signal input portion 11 and the second signal input portion 21 to the host computer 40. In an alternative example, the first signal output part 12 and/or the second signal output part 13 comprise electrode connectors. The connecting structure of the electrode connecting buckle is adopted, and the first signal output part 12 and/or the second signal output part 13 are/is electrically connected with the host 40, so that certain mechanical connection strength can be kept, the connection is stable, the operation is convenient, and the stability of signal transmission is improved. Of course, in other embodiments, the first signal output unit 12 and/or the second signal output unit 13 may be configured to be connectable to the host 40, which is not limited by the present utility model. Further, the first signal output portion 12 and the second signal output portion 13 are both integrally disposed on the first sensing unit 10, which is beneficial to centralized arrangement, reduces the volume of the host 40, and is convenient for portable application.

Optionally, the first sensing unit 10, the second sensing unit 20, and the connection unit 30 include a flexible substrate 51 and a flexible conductive circuit 52, respectively, and the flexible conductive circuit 52 is disposed on a side of the flexible substrate 51 away from the target object; when the first sensing unit 10, the second sensing unit 20, and the connection unit 30 are in an initial state without external force, the extending direction of the first sensing unit 10 and the extending direction of the second sensing unit 20 are located on the same plane, and the flexible substrate 51 extends in a flat shape on the plane; the first signal output part 12 is electrically connected with the first signal input part 11 through a part of flexible conductive line 52 of the first sensing unit 10; the second signal output portion 13 is electrically connected to the second signal input portion 21 through another portion of the flexible conductive trace 52 of the first sensor unit 10, the flexible conductive trace 52 of the second sensor unit 20, and the flexible conductive trace 52 of the connection unit 30.

Since the flexible substrate 51 and the flexible conductive trace 52 are flexible, the first sensor unit 10, the second sensor unit 20, and the connection unit 30 can bend and deform when an external force is applied, and can adapt to the outer contour shape of the target object, so that they can be attached to the skin surface.

In an alternative example, the flexible substrate 51 comprises a medical non-woven fabric tape, and the flexible conductive trace 52 comprises a flexible substrate (e.g., PVC substrate) and a flexible conductor of metal paste, such as metal paste (e.g., silver paste) printed on the substrate. Of course, in other embodiments, flexible conductive trace 52 may comprise a conventional flexible conductive wire, as the utility model is not limited in this regard. Further, the flexible conductive trace 52 is located on the side of the flexible substrate 51 away from the target object, i.e., on the front side of the flexible substrate 51, instead of being sandwiched between two nonwoven tapes. So configured, the flexible conductive trace 52 does not contact the skin during use, and only one layer of nonwoven fabric is advantageous for increased breathability and comfort, for long-term application to the skin surface, and for reduced cost.

Alternatively, when the first sensor unit 10, the second sensor unit 20, and the connection unit 30 are in the initial state without external force, the flexible substrate 51 of the connection unit 30 extends in a belt shape on the plane, wherein the flexible substrate 51 of the serpentine section is in a reciprocating belt shape with a meandering shape. The direction of extension of the connection unit 30 is in general direction perpendicular to the direction of extension of the first sensor unit 10.

Optionally, in some embodiments, the first sensing unit 10 and the second sensing unit 20 are respectively fixedly connected to the connection unit 30, that is, the whole electrocardiographic sensing assembly is integrated. As shown in fig. 2 to 5, the flexible substrate 51 of the first sensing unit 10, the second sensing unit 20 and the connecting unit 30 are integrally formed, and a part of the flexible conductive circuit 52 of the first sensing unit 10, a part of the flexible conductive circuit 52 of the second sensing unit 20 and a part of the flexible conductive circuit 52 of the connecting unit 30 are integrally formed, so that the flexible conductive circuit is not easy to break due to welding, and is more comfortable to use. Since the flexible substrate 51 of the connection unit 30 preferably extends in a band shape having a certain width, the connection unit 30 can define the relative angles of the first sensing unit 10 and the second sensing unit 20 (i.e., the angle between the extending direction of the first sensing unit 10 and the extending direction of the second sensing unit 20), respectively. Further, the connection unit 30 itself has a certain axial length (refer to a length perpendicular to the extending direction of the first sensor unit 10) in the initial state, which is a limitation of the relative distance between the first sensor unit 10 and the second sensor unit 20 (particularly, the closest distance between the first sensor unit 10 and the second sensor unit 20 in the extending direction of the first sensor unit 10 when the extending direction of the first sensor unit 10 is arranged parallel to the extending direction of the second sensor unit 20 in the initial state without external force). The scheme of integrally forming the first sensing unit 10, the second sensing unit 20 and the connecting unit 30 is convenient to manufacture, and the connection firmness and reliability of the three parts in use are high, so that the accuracy of electrocardiosignals is guaranteed. In particular, the flexible conductive circuit 52 for connecting the second signal input portion 21 and the second signal output portion 13 is integrally formed, so that the connection joint required for interconnection is avoided, welding is not required, reliability is high, breakage is not easy, and use is more comfortable.

With continued reference to fig. 2 and 3, in a first preferred example of the electrocardiographic sensing assembly, the electrocardiographic sensing assembly includes four first signal input portions 11, four first signal output portions 12, two second signal input portions 21 and two second signal output portions 13, wherein the four first signal output portions 12 and the two second signal output portions 13 are located in the middle of the first sensing unit 10 and are arranged in three rows and two columns, and wherein two rows of the upper portion (refer to a side far from the second sensing unit 20) are four first signal output portions 12 which are electrically connected with the four first signal input portions 11 through four flexible conductive lines 52 extending to both sides of the first sensing unit 10, respectively. The lower portion (refer to the side close to the second sensing unit 20) serves as two second signal output portions 13, which are electrically connected to the two second signal input portions 21 on the second sensing unit 20 through the connection unit 30 by two flexible conductive traces 52, respectively. So configured, the trace length of the flexible conductive trace 52 is advantageously shortened, thereby advantageously increasing the accuracy of signal transmission.

Referring to fig. 4, in a second preferred example of the electrocardiographic sensing assembly, four first signal input portions 11, four first signal output portions 12, two second signal input portions 21, and two second signal output portions 13 are also included. In the second preferred example, the arrangement order of the four first signal output sections 12 and the two second signal output sections 13 is different from that of the first preferred example shown in fig. 2 and 3. Specifically, among the 6 signal output units arranged in three rows and two columns, the left one column of 3 signal output units is the first signal output unit 12. One signal output portion at the lower part of the right row is a first signal output portion 12, and two signal output portions at the upper part of the right row are second signal output portions 13. It should be understood that the above two preferred examples are merely exemplary of the number and arrangement of the signal input parts and the signal output parts, and are not limited thereto, and those skilled in the art may variously arrange and arrange the number and arrangement of the signal input parts and the signal output parts according to actual practice.

Optionally, in other embodiments, at least one of the first sensing unit 10 and the second sensing unit 20 is detachably connected with the connection unit 30. It will be appreciated that since the connection unit 30 is detachable from the first sensing unit 10 or the second sensing unit 20, it is a split type scheme as compared to the integrated scheme of the previous embodiment. The split type scheme can make the different parts of being separated can carry out nimble combination and use, improves the application scope of electrocardio sensing component, and the cost of manufacture is also lower than the electrocardio sensing component of integral type, and when electrocardio sensing component packs and deposits simultaneously, also can be more nimble, and whole packing size is littleer, and for example the different parts of being separated can pack respectively, also can set up in a packing side by side, and storage space is also littleer, and the person of facilitating the use carries with oneself.

As shown in fig. 5a, 5b and 6, in a third preferred example of the electrocardiographic sensing assembly, the first sensing unit 10 is detachably connected to the connection unit 30, and the second sensing unit 20 is fixedly connected to the connection unit 30 to form a combination 60; the electrocardiographic sensing assembly comprises a plurality of assemblies 60 with different specifications, and the first sensing unit 10 is used for selecting one of the assemblies 60 with different specifications for connection.

Further, the first sensing unit 10 includes at least one first signal input part 11 and at least one first signal output part 12, the connection unit 30 includes at least one second signal output part 13, and the second sensing unit 20 includes at least one second signal input part 21; the first signal output part 12 is electrically connected to the corresponding first signal input part 11; the second signal output section 13 is electrically connected to the corresponding second signal input section 21.

And the combination 60 formed by the second sensing unit 20 and the connecting unit 30 has a plurality of different specifications to match different usage scenarios. Different specifications here may refer to that the connection unit 30 has serpentine regions of different lengths or different shapes. In other embodiments, different specifications may refer to that the connection unit 30 and the second sensing unit 20 have different angles, and may refer to that the second sensing unit 20 has different numbers of second signal input portions 21, which may be configured by those skilled in the art according to practical implementation.

Since the first sensor unit 10 is mainly used for being laid at a first predetermined position, such as a position under the collarbone, the position and range of application thereof are substantially fixed, and are not greatly changed due to different physical constitutions of different patients, it can be configured as a general unit. The plurality of assemblies 60 with different specifications can cope with different use situations, and patients can select to use only the first sensing unit 10 or use only the assemblies 60 according to needs, and can flexibly match the first sensing unit 10 with the assemblies 60 with different specifications, so that compared with an integrated electrocardiograph sensing assembly, the matching flexibility is better, and the processing cost and the packaging volume can be reduced. Of course, the above-mentioned splitting manner is only an example of a split type scheme, and in other embodiments, according to different requirements, a person skilled in the art may also fixedly connect the first sensing unit 10 with the connecting unit 30 to form a combination and detachably connect the first sensing unit 10 with the second sensing unit 20, or detachably connect the first sensing unit 10, the second sensing unit 20 with the connecting unit 30.

The connection unit 30 and the flexible conductive circuit 52 of the second sensing unit 20 are also integrally formed, and the flexible conductive circuit 52 sequentially extends from the second signal input portion 21 through the flexible substrate 51, the strip-shaped extension portion 511 and the connection portion 512 of the second sensing unit 20 to be connected with the second signal output portion 13 on the connection portion 512, so as to realize the electrical connection between the second signal input portion 21 and the second signal output portion 13.

The connection section 512 can then be detachably mounted on the first sensor unit 10, for example by gluing or velcro connection. As shown in fig. 6, optionally, the area of the first sensor unit 10 for mounting the connection section 512 may be distinguished by marking or providing physical limitation, so that the connection section 512 can be mounted at a predetermined position of the first sensor unit 10. So configured, after the assembly 60 is assembled and connected with the first sensor unit 10, the second signal output portion 13 also becomes a part of the first sensor unit 10, so as to facilitate the installation of the subsequent host 40.

In the preferred embodiment, the flexible substrate 51 of the second sensing unit 20 and the connecting unit 30 are integrally formed, and the flexible conductive traces 52 of the second sensing unit 20 and the connecting unit 30 are also integrally formed, so that the flexible conductive traces are not easy to break due to welding, and are more comfortable to use.

In some embodiments, the adhesive layer, such as a self-adhesive, is disposed on the back of the flexible substrate 51 and may be applied directly to the skin during use. The release film layer is used for protecting the adhesive layer before use and can be torn off when in use. Preferably, the first sensing unit 10, the second sensing unit 20, and the connecting unit 30 all include an adhesive layer and a release film layer, and when in use, all three can be respectively attached to the target object.

Referring to fig. 7 and 8, an embodiment of the present utility model further provides an electrocardiographic device, which includes an electrocardiographic component as described above, and further includes a host 40; the host 40 is detachably connected to the electrocardiograph sensing assembly, and the host 40 is used for acquiring electrocardiograph signals sensed by the electrocardiograph sensing assembly. In an alternative example, the electrode connectors of the first signal output portion 12 and the second signal output portion 13 are male connectors, which are protruded toward the front. The host 40 is provided with a plurality of female buckles matched with the male buckles, the number and the arrangement of the female buckles are the same as those of the male buckles, and the host 40 can be directly buckled on the electrocardiograph sensing assembly, and the electric conduction between each signal output part and the host 40 is realized, so that an electrocardiograph signal transmission path is formed. The buckling connection mode is very convenient in assembly connection and high in connection reliability. Alternatively, the host 40 is an electrocardiograph device host, and the structure and principle of other parts of the host 40 can refer to the prior art, and the present utility model will not be described further.

In summary, in the electrocardiographic sensing assembly and the electrocardiographic sensing device provided by the present utility model, the electrocardiographic sensing assembly includes a first sensing unit, a second sensing unit and a connection unit; the first sensing unit is used for being laid at a first preset position of the target object; the second sensing unit is used for being laid at a second preset position of the target object; the connecting unit is respectively connected with the first sensing unit and the second sensing unit; wherein the connection unit is adapted to deform when the relative distance and/or relative angle of the first and second sensing units changes. So configured, by the arrangement of the connection units, the initial relative distance and/or the initial relative angle of the first sensing unit and the second sensing unit is limited in the initial state, thereby facilitating the application of the electrocardiographic sensing assembly to a suitable angular position. Further, when the relative distance and/or the relative angle of the first sensing unit and the second sensing unit change, the connecting unit adaptively deforms, so that the connection part of the first sensing unit and the second sensing unit and the connecting unit is effectively prevented from being pulled, and the stability and the accuracy of signal transmission are improved. In addition, because when the relative distance and/or the relative angle of the first sensing unit and the second sensing unit change, the connecting unit is adaptively deformed, so that the relative distance and the relative angle of the first sensing unit and the second sensing unit can be adjusted, and the electrocardiographic sensing assembly can be conveniently laid at a proper angle position, so that the electrocardiographic sensing assembly can be suitable for more monitoring positions and different crowds, the accuracy of signal acquisition is improved, and the physical examination and monitoring effects of users are improved.
