Description

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;

the problem with such an electrocardio sensor is that, on the one hand, the second portion 02 is often attached at a certain angle, but how to attach the second portion 02 to a proper angle position has a great operation difficulty for common consumers, which affects the use experience and the monitoring result.

The utility model aims to provide an electrocardiograph sensing assembly and an electrocardiograph sensing device, which are used for solving the problem of poor attaching accuracy of the traditional electrocardiograph sensor.

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; the connection unit 30 serves to limit the relative distance and the relative angle of the first sensing unit 10 and the second sensing unit 20.

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.

In an example of a use scenario, the first sensing unit 10 is attached to the target object at a position substantially below the collarbone of the target object in the cross-sectional direction thereof, i.e. the first predetermined position is relatively easy to determine. After the first sensing unit 10 is correctly laid, the connection unit 30 limits the relative distance and the relative angle between the first sensing unit 10 and the second sensing unit 20, so that the laying of the second sensing unit 20 which is difficult to position is not required to be searched and adjusted, and the first sensing unit is directly laid, so that an electrocardiograph sensing assembly is laid at a proper angle position, the judgment of the laying position is simplified, the manual operation error is reduced, the accuracy of signal acquisition is improved, and the physical examination and monitoring effect of a user are improved.

Further, the connection unit 30 has a fixed angle with the first sensing unit 10, and the connection unit 30 has a fixed angle with the second sensing unit 20; when the connection unit 30 is in an initial state without an external force, the connection unit 30 is in a straight line shape. In the examples shown in fig. 2 and 3, the connection unit 30 is perpendicular to the extending direction of the first sensor unit 10, and the angle between the connection unit 30 and the extending direction of the second sensor unit 20 is also fixed, preferably at a predetermined angle between 45 ° and 60 °.

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 the at least two second signal input parts 21 are arranged along the extending direction of the second sensing unit 20; the angle between the extending direction of the second sensing unit 20 and the extending direction of the first sensing unit 10 is 30 ° to 45 °.

In one exemplary embodiment, the outer contour shape of the first sensing unit 10 is substantially elongated, and the extending direction of the first sensing unit 10 refers to the length direction thereof. 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. For example, in the example shown in fig. 2 and 3, the extending direction of the first sensing unit 10 is a horizontal direction. 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. The second sensing unit 20 extends in a direction from approximately the fourth intercostal space of the right sternum edge to the left xiphoid process, and in the example shown in fig. 2, the second sensing unit 20 extends in a direction from the upper left to the lower right, and has an angle of approximately 30 ° to 45 ° with respect to the horizontal direction.

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. The initial state as referred to herein refers to a state when the first sensor unit 10, the second sensor unit 20, and the connection unit 30 are not subjected to external force, and can be considered as a design form of the product.

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 band shape on the plane, and the length direction of the band shape is perpendicular to the extending direction of the first sensor unit 10 and is disposed at an angle to the extending direction of the second sensor unit 20. Since the connection unit 30 extends in a band shape on the plane, a center line of the flexible substrate 51 extending in a band shape may be referred to as an axis of the connection unit 30.

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 substrates 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, the flexible conductive circuit 52 of the second sensing unit 20 and the flexible conductive circuit 52 of the connecting unit 30 are integrally formed, so that welding is not required, and the flexible conductive circuit is not easy to break 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 in a direction perpendicular to the extending direction of the first sensing unit 10, the connection unit 30 can define the relative angle 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, after the connection unit 30 is straightened, it defines the relative distance of the first sensor unit 10 and the second sensor unit 20 (i.e. the distance of the first sensor unit 10 and the second sensor unit 20 along the axis of the connection unit 30, in particular the distance where the axes of the first sensor unit 10 and the second sensor unit 20 intersect the axis of the connection unit 30). 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. It can be appreciated that, after the first sensor unit 10, the second sensor unit 20 and the connecting unit 30 are assembled and connected, the connecting unit 30 can also define the relative distance and the relative angle between the first sensor unit 10 and the second sensor unit 20. 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, 5c 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.

In this third preferred example, the first sensor unit 10 is a universal unit, as shown in fig. 5 a.
