Technical Field

[0003] The invention belongs to the technical field of portable electrocardiograph design, and in particular relates to a portable electrocardiograph. Background Art

[0004] The electrocardiogram (ECG) is an important tool for detecting cardiovascular disease. Electrodes covering the human body (also known as detection electrodes) collect bioelectrical signals to record cardiac activity patterns. Twelve-lead ECGs, clinically used for medical diagnostics, often use the Wilson 12-lead system. This structure has numerous wires, which are prone to tangling, and complex detection point locations, requiring specialized personnel to perform. This makes it difficult for the general public to use.

[0005] Based on the aforementioned deficiencies of the traditional twelve-lead ECG, the applicant previously proposed a portable twelve-lead ECG. However, most of these ECGs are not equipped with corresponding display components. The display of ECG-related parameters requires the use of smart terminals such as mobile phones and tablets, and data collection and analysis through network or Bluetooth connection. These devices have certain limitations and are easily restricted by terminal devices or networks. In addition, since a considerable proportion of ECG users are elderly people, there are certain obstacles for the elderly to use smartphones, which makes it difficult for these users to view ECG parameters using smart terminals, which reduces the use and promotion of ECG.

[0006] Some portable ECG devices have been proposed in the related art, but these portable ECG devices are difficult to adapt to the individual differences in body shape of different users due to design problems, especially for the V6 detection electrode, which needs to be more accurately positioned at the midline position of the axillary area between the 3 / 4 ribs on the left side of the human body during specific detection, and the fixed-length bracket arm cannot adapt to different body shapes, especially users with large differences in weight. In particular, for the bracket arm with a flip-up storage design, since the position of the flip connection is relatively fixed, the position of the V6 detection electrode of users of different body shapes cannot be adjusted by changing the relative position between the bracket arm and the bracket body. During ECG detection, there is a risk of distortion in the ECG detection output result because the detection electrode contacts cannot be accurately positioned at the target position.

[0007] It can be seen that whether it is possible to provide a portable electrocardiograph with an improved structure based on the deficiencies in the existing technology so that it is compact, easy to carry, convenient to locate and easy to use has become a technical problem that needs to be solved urgently by those skilled in the art.

[0060] The portable electrocardiograph provided by the present invention has the following beneficial effects:

[0061] The ten detection electrodes are reasonably arranged on the bracket body, upper bracket arm, lower bracket arm and side bracket arm according to the ECG detection position, and the corresponding electrode wires are laid out inside the bracket. The structure is compact, which eliminates the entanglement problem caused by long and numerous cables in the existing technology; each bracket arm can be flipped and connected to the corresponding edge of the bracket body. When the user needs to detect the ECG, each bracket arm can be easily positioned when it is unfolded. No professional operation is required. The user only needs to locate and complete the ECG detection according to the reference positioning benchmark on the bracket body. The operation and detection are easy and effective. This is conducive to promoting the progress of electrocardiograms into homes, making it possible for patients to test electrocardiograms at home; when there is no need to test the electrocardiogram, each bracket arm can be flipped and folded toward the side close to the proximal surface of the bracket body to achieve quick storage of each bracket arm, making the structure of the electrocardiograph in the stored state compact; it should be noted that in the flipped and folded storage state, the detection surface of each detection electrode on each bracket arm will face the proximal surface of the bracket body, and the whole is hidden inwardly, which can protect the detection electrodes and effectively reduce the probability of damage to each detection electrode caused by wear or falling;

[0062] The concave-convex matching structure of the first protrusion on the locking key and the ring groove on the V6 detection electrode realizes the locking of the opposite side bracket arm, which has a simple structure and convenient locking operation;

[0063] The locking button can lock both the contralateral bracket arm and the ECG device, streamlining the structural design of the ECG device and making the overall structure of the ECG detection electrode bracket more compact.

[0064] The lock key has two sliding distances. A short sliding distance unlocks the side bracket arm so that ECG detection can be performed. A long sliding distance unlocks the ECG device host so that the host can be replaced.

[0065] In some embodiments, an electrocardiograph host is integrated on the detection electrode bracket. The display screen component of the electrocardiograph host can directly display the electrocardiograph parameters output by the electrocardiograph detection circuit board without the user having to use a mobile phone, tablet computer or other smart terminal for display. Therefore, it is no longer restricted by the terminal device or network, and is particularly suitable for use by the elderly and easy to use and promote among the elderly.

[0066] In some embodiments, on the one hand, the first end of the ECG detection electrode bracket arm is connected to the bracket body in a flippable manner, so that the proximal surface of the bracket arm can be opposite to the proximal surface of the bracket body after flipping, thereby achieving improved structural compactness of the bracket arm when folded and stored, while forming physical protection for each detection electrode on the bracket arm to prevent damage to the detection electrodes; on the other hand, based on the flippability of the bracket arm, the bracket arm is designed to be a retractable structure, so that the second detection electrode thereon can be adjusted and accurately positioned at the target position of different body shapes according to the different body shapes of users, thereby improving the accuracy of the ECG detection output results of the electrocardiograph.

Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0106] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0107] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0108] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0109] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0111] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0112] 1 to 9 , according to an embodiment of the present invention, there is provided an electrocardiogram detection electrode holder, comprising: a holder body 21, on the distal surface of which is provided with an LA detection electrode 211 and an RA detection electrode 212 corresponding to the left arm and the right arm of the user to be detected, respectively, and on the proximal surface of which is provided a V3 detection electrode 213 and an RL detection electrode 214; an upper holder arm 22, connected to the upper edge of the holder body 21, on the proximal surface of which is provided a V1 detection electrode 221 and a V2 detection electrode 222; a lower holder arm 23, connected to the lower edge of the holder body 21, on the proximal surface of which is provided an LL detection electrode 231; a side holder arm 24, connected to the left edge of the holder body 21 to correspond to the chest side of the user to be detected where the heart is located, and on the proximal surface of which are provided V4 detection electrodes 241 and V5 detection electrodes 242. Detection electrode 242 and V6 detection electrode 243; the upper support arm 22, the lower support arm 23 and the side support arm 24 can all flip around their respective connection positions with the support body 21 toward the close body surface of the support body 21 to a target angle, and the aforementioned upper edge, lower edge and left edge are all determined by the orientation of the electrocardiograph of the present invention relative to the user to be detected when in use. The aforementioned target angle is limited to the maximum angle to which the upper support arm 22, the lower support arm 23 and the side support arm 24 can flip close to the close body surface of the support body 21, so that the storage of each support arm is more compact. In a specific embodiment, the target angle to which the upper support arm 22 and the lower support arm 23 can flip should be no less than 90°, and the target angle to which the side support arm 24 can flip should be no less than 120°. The aforementioned ten detection electrodes, namely LA detection electrode 211, RA detection electrode 212, V3 detection electrode 213, RL detection electrode 214, V1 detection electrode 221, V2 detection electrode 222, LL detection electrode 231, V4 detection electrode 241, V5 detection electrode 242 and V6 detection electrode 243, have the same naming rules as the relevant detection electrodes (columns or sheets) of a traditional twelve-lead electrocardiograph. The arrangement positions of the detection electrodes are designed according to ergonomics and meet the requirements of the known twelve-lead Wilson positioning system. The present invention does not impose any special limitations on them.

[0113] In this technical solution, ten detection electrodes are reasonably arranged on the bracket body 21, the upper bracket arm 22, the lower bracket arm 23 and the side bracket arm 24 according to the ECG detection position, and the corresponding electrode wires are laid out inside the bracket. The structure is compact, and the entanglement problem caused by the long and numerous cables in the existing technology is eliminated; each bracket arm can be flipped and connected to the corresponding edge of the bracket body 21. When it is necessary to detect the ECG of the user to be detected, each bracket arm can be easily positioned when it is unfolded, and no professional operation is required. The user to be detected can be positioned and complete the ECG detection based on the reference positioning benchmark on the bracket body 21. The detection is easy to perform, which is conducive to promoting the progress of electrocardiogram into the home, making it possible for patients to detect electrocardiogram at home; when there is no need to detect the electrocardiogram, each bracket arm is flipped and folded toward the side close to the proximal surface of the bracket body 21 to achieve quick storage of each bracket arm, so that the structure of the electrocardiograph in the stored state is compact; it should be noted that the detection surface of each detection electrode on each bracket arm in the flipped and folded storage state will face the proximal surface of the bracket body 21, and the whole is hidden inward, which can protect the detection electrode and effectively reduce the chance of damage to each detection electrode caused by wear or falling.

[0114] The aforementioned near side refers to the side of the wall close to the user to be tested when the electrocardiograph is in use, while the far side refers to the side of the wall far away from the user to be tested in this state. The near side and the far side are opposite to each other.

[0115] The aforementioned upper support arm 22, lower support arm 23 and side support arm 24 can all be connected to the support body 21 in a reversible manner through an existing torsion shaft structure (not shown or labeled in the figure). When the electrocardiograph is in the electrocardiograph detection state, each torsion shaft structure can apply force to each corresponding support arm so that each support arm has a tendency to flip toward the reversible storage state.

[0116] In order to ensure the position of each detection electrode, the length of the side support arm 24 is designed to be longer, while the lengths of the upper support arm 22 and the lower support arm 23 are designed to be relatively shorter.

[0117] In some embodiments,

[0118] A locking component (not marked in the figure) is provided on the proximal surface of the bracket body 21, and the side bracket arm 24 has a detection position (corresponding to the ECG detection state of the electrocardiograph) and a storage position (corresponding to the flipped storage state of the electrocardiograph). When the side bracket arm 24 is in the detection position, the V4 detection electrode 241, the V5 detection electrode 242 and the V6 detection electrode 243 are respectively in the preset ECG detection position. When the side bracket arm 24 is in the storage position, the locking component locks the side bracket arm 24 so that the proximal surface of the side bracket arm 24 is opposite to the proximal surface of the bracket body 21.

[0119] Since three detection electrodes are provided on the side bracket arm 24 and its length is relatively large, its own mass is also relatively large. The torsional shaft structure between it and the bracket body 21 will weaken its torsional effect when used for a long time, which will cause the side bracket arm 24 to be unable to be reliably and stably in the aforementioned storage position. The loose state will reduce the user's satisfaction with use. More importantly, the corresponding detection electrodes are very likely to randomly collide with external objects due to the unreliable storage position, thereby damaging the detection electrodes. In this technical solution, a locking component is provided on the proximal surface of the bracket body 21 to ensure that the side bracket arm 24 can be reliably and stably in the storage position, effectively preventing the detection electrodes thereon from being damaged by direct collision with external objects.

[0120] 6 to 9 , the V4 detection electrode 241, the V5 detection electrode 242 and the V6 detection electrode 243 are spaced apart along the length direction of the arm of the side bracket arm 24 from the side close to the bracket body 21 toward the side away from the bracket body 21. The locking component includes a locking key 25. The locking key 25 has a first locking position and a first unlocking position. The V6 detection electrode 243 has an annular groove 2431. The locking key 25 has a first protrusion 251. When the side bracket arm 24 is in the storage position, the first protrusion 251 is at least partially inserted into the annular groove 2431 to be in the first locking position. When the locking key 25 is in the first unlocking position, the first protrusion 251 is disengaged from the annular groove 2431.

[0121] In this technical solution, the locking of the opposite bracket arm 24 is achieved through the concave-convex matching structure of the first protrusion 251 on the locking key 25 and the annular groove 2431 on the V6 detection electrode 243. The structure is simple and the locking operation is convenient.

[0122] 1 and 2 , in some embodiments, an assembly hole 215 for embedding the electrocardiograph host 3 is constructed on the bracket body 21. The assembly hole 215 is roughly located in the central area of ​​the bracket body 21. The locking key 25 also has a second locking position and a second unlocking position. The side wall of the electrocardiograph host 3 has a groove (not shown or labeled in the figure). The locking key 25 also has a second protrusion 252. When the electrocardiograph host 3 is embedded in the assembly hole 215, the second protrusion 252 is at least partially inserted into the groove to be in the second locking position. When the locking key 25 is in the second unlocking position, the second protrusion 252 is out of the groove. The electrocardiograph host 3 is embedded in the assembly hole 215, and is electrically connected (for example, a communication connection) to each detection electrode through the electrical connection component 2151. The embedded structure is a detachable structure, so that different types of electrocardiograph hosts 3 can be configured according to the actual needs of the user. For example, a host with a display component 32 or a host without a display component can be selected. The aforementioned electrical connection component 2151 can specifically adopt a commercially available pogopin interface.

[0123] In this technical solution, the locking key 25 also locks the ECG main unit 3 through the second protrusion 252, so that the ECG main unit 3 can be stably and reliably embedded in the assembly hole 215. Therefore, the locking key 25 in the present invention can simultaneously achieve the locking purpose of both the contralateral bracket arm 24 and the ECG main unit 3, simplifying the structural design of the ECG, which makes the overall structure of the ECG detection electrode bracket further compact.

[0124] It can be understood that a host fixing protrusion 2152 is further provided on the inner wall of the assembly hole 215 on the side opposite to the second protrusion 252, which can be inserted into the corresponding card slot on the electrocardiograph host 3, thereby further improving the position reliability of the electrocardiograph host 3 in the assembly hole 215.

[0125] 8 and 9 , in some embodiments,

[0126] The locking key 25 is slidably connected to a slide groove (not shown in the figure) on the bracket body 21, and an elastic member 254 is provided between the locking key 25 and the bracket body 21. The elastic member 254 can exert an elastic force on the locking key 25 so that the locking key 25 can slide close to the V6 detection electrode 243 in the storage position and the electrocardiograph host 3 in the embedded position.

[0127] During specific use, when the electrocardiograph needs to be used for electrocardiograph detection, the user applies force on the locking key 25 to overcome the elastic force applied by the elastic member 254, driving the locking key 25 to slide away from the V6 detection electrode 243 and the electrocardiograph host 3. At this time, the first protrusion 251 disengages from the annular groove 2431 and / or the second protrusion 252 disengages from the groove, thereby releasing the lock on the opposite side support arm 24 and / or the electrocardiograph host 3, and the electrocardiograph can be put into the electrocardiograph detection state. When it is necessary to lock the electrocardiograph host 3 or the side support arm 24, the user only needs to press down the electrocardiograph host 3 or the side support arm 24. When the position of the groove or the annular groove 2431 corresponds to the position of the second protrusion 252 or the first protrusion 251, the locking key 25 will slide close to the electrocardiograph host 3 or the side support arm 24 under the action of the elastic force of the elastic member 254, thereby realizing the snap-on locking of the aforementioned components. The operation is very simple and convenient. In a preferred embodiment, the locking key 25 includes a force-applying protrusion 253 protruding from the proximal surface of the support body 21. To unlock the contralateral support arm 24 and the electrocardiograph main unit 3, the user simply applies force to the force-applying protrusion 253 in a direction away from the aforementioned components, which is simple and convenient. The aforementioned elastic member 254 can be a coil spring.

[0128] In some embodiments,

[0129] The insertion and fitting depth of the first protrusion 251 and the annular groove 2431 is smaller than the insertion and fitting depth of the second protrusion 252 and the groove. In this way, by designing the insertion and fitting depth of the first protrusion 251 and the annular groove 2431 to be smaller than the insertion and fitting depth of the second protrusion 252 and the groove, it is possible to unlock the side bracket arm 24 without unlocking the electrocardiograph host 3. Specifically, the locking key 25 has two sliding distances. The short distance sliding unlocks the side bracket arm 24, and electrocardiograph detection can be performed. The long distance sliding unlocks the electrocardiograph host 3, and the host can be replaced at this time. It should be noted that when the locking key 25 slides at the aforementioned two distances, due to the action of the compressive elastic force of the aforementioned elastic member 254, the long distance sliding requires the user to apply greater force. This can effectively prevent the misunderstanding of locking the electrocardiograph host 3 when unlocking the side bracket arm 24 for electrocardiograph detection, and prevent the electrocardiograph host 3 from accidentally falling and causing damage. As a more preferred embodiment, the proximal edge of the side support arm 24 has a third protrusion (not shown in the figure). When the side support arm 24, the upper support arm 22 and the lower support arm 23 are all in the storage position, the third protrusion forms a snap connection with the V1 detection electrode 221, the V2 detection electrode 222 and the LL detection electrode 231 to prevent the upper support arm 22 and the lower support arm 23 from flipping away from the support body 21.

[0130] In this technical solution, when the electrocardiograph is in the flipped storage state, the side support arm 24 interlocks the upper support arm 22 and the lower support arm 23 through the third protrusion, preventing the upper support arm 22 and the lower support arm 23 from flipping away from the support body 21 in the folded storage state, thereby protecting the detection electrodes on the upper support arm 22 and the lower support arm 23. Therefore, it can be understood that when storing the support arms, the upper support arm 22 and the lower support arm 23 should be flipped and stored in place first, and then the side support arm 24 should be flipped and stored, so that the side support arm 24 objectively blocks the outward rotation path of the upper support arm 22 and the lower support arm 23.

[0131] The LA detection electrode 211 and the RA detection electrode 212 are detection electrode sheets. When the electrocardiograph is in the electrocardiograph detection state, the left and right hands of the user to be detected can be placed on the LA detection electrode 211 and the RA detection electrode 212 respectively, so that the user can hold the electrocardiograph and position it while realizing the electrocardiograph detection of the user's left and right arms; the V1 detection electrode 221, the V2 detection electrode 222, the V3 detection electrode 213, the V4 detection electrode 241, the V5 detection electrode 242, the V6 detection electrode 243, the RL detection electrode 214, and the LL detection electrode 231 are all detection electrode columns.

[0132] Referring to Figures 10 to 13, according to an embodiment of the present invention, specifically referring to Figure 10, there is provided an electrocardiograph host 3, comprising a host component 3131 and a display component 3232. The electrocardiograph host 3 is assembled on the distal surface of the bracket body 21 through the host component 31. The host component 31 comprises a host housing 311 and an electrocardiograph detection circuit board 312 arranged in the host housing 311. The electrocardiograph detection circuit board 312 is electrically connected to each of the detection electrodes (through a wire, not shown in the figure). The display component 32 comprises a display screen assembly 322, which is at least used to display the electrocardiograph parameters output by the electrocardiograph detection circuit board 312. Specifically, the aforementioned host housing 311 can The host comprises a main body top shell and a main body bottom shell that are relatively snap-fitted and assembled, and a main body accommodating space is formed between the main body top shell and the main body bottom shell. The aforementioned ECG detection circuit board 312 is arranged in the main body accommodating space. The ECG detection circuit board 312 is equipped with corresponding chips and other electronic components for electrically connecting with each detection electrode assembly to perform routine operations such as processing and analysis on the acquired ECG signals (bioelectric signals). The processing and analysis of the aforementioned ECG signals by the ECG detection circuit board 312 are routine operations in the industry and are not the protection content of the present invention, so they will not be elaborated here. The aforementioned ECG parameters, such as heart rate, ECG curve, etc., are based on the position of the user when using the portable ECG device. The main body component 31 is on the side of the display component 32 close to the human body being detected.

[0133] In this technical solution, an electrocardiograph host 3 is integrated on the detection electrode bracket 2. The display screen component 322 of the electrocardiograph host 3 can directly display the electrocardiograph parameters output by the electrocardiograph detection circuit board 312 without the user having to use a mobile phone, tablet computer or other smart terminal for display. Therefore, it is no longer restricted by terminal equipment or network, and is particularly suitable for use by the elderly and easy to use and promote among the elderly.

[0134] In some embodiments,

[0135] The display component 32 has a display shell 321, and the display screen assembly 322 is located on a side surface of the display shell 321 away from the main body shell 311. The first side of the display shell 321 is pivotally connected to the first side of the main body shell 311 through a pivot structure (not marked in the figure). The display component 32 can be driven to open and close relative to the main body component 31 around the pivot structure. The aforementioned pivot structure can specifically adopt a commonly used shaft connection structure, and preferably a commercially available damping shaft is used to realize the opening and closing connection between the main body component 31 and the display component 32, so that the opening and closing process of the display component 32 is smooth and stable.

[0136] In this technical solution, the display component 32 can be driven (e.g., manually applied by the user) to expand (as shown in FIG. 10 ) or engage (as shown in FIG. 11 ) relative to the main unit 31 around the pivot structure between the display component 32 and the main unit 31. The user can select the expansion angle according to their viewing angle requirements, thereby facilitating the user to directly view the ECG parameters on the display screen assembly 322 during ECG monitoring, and to immediately determine the validity of their operation and detection data. When the display component 32 and the main unit 31 are in the expanded state, the maximum expansion angle formed between the two is generally designed to be no less than 90°. The user can reasonably adjust the expansion angle according to their needs. It is understood that, based on the state of the user using the ECG monitor, the pivot structure is located near the user's head, that is, the opening of the expansion angle is toward the user's lower limbs.

[0137] In some embodiments,

[0138] The bracket body 21 is provided with an assembly hole 215, and the main unit component 31 is embedded in the assembly hole 215. The bottom wall of the main unit housing 311 is provided with an electrical adapter component 34 electrically connected to the ECG detection circuit board 312. The wall of the assembly hole 215 is provided with an electrical connection component 2151 electrically connected to each of the detection electrodes. When the main unit component 31 is assembled in the assembly hole 215, the electrical connection component 2151 is connected to the electrical adapter component 34. In this technical solution, the electrical connection component 2151 on the wall of the assembly hole 215 and the electrical adapter component 34 on the bottom wall of the main unit housing 311 are connected to each other. The detachable electrical connection between the ECG main unit 3 and the detection electrode bracket 2 and each of the detection electrodes thereon is achieved by docking the electrical connection component 2151 on the wall of the assembly hole 215 with the electrical adapter component 34 on the bottom wall of the main unit housing 311. The detachable connection between the ECG main unit 3 and the detection electrode bracket 2 can improve the maintainability and functional expandability of the ECG.

[0139] In a specific embodiment, the electrical connection component 2151 and the electrical adapter component 34 are spring pin connectors that match each other (such as commercially available pogopin interfaces). At this time, the electrical connection component 2151 and the electrical adapter component 34 can be electrically connected during the process of embedding the electrocardiograph host 3 and the assembly hole 215. It can be understood that at this time, the electrocardiograph host 3 can be inserted and embedded in the assembly hole 215 in a direction that is almost parallel to the depth direction of the assembly hole 215. This assembly method can make the structural design of the detection electrode bracket 2 more reasonable, so that the detection electrodes thereon can be more conveniently arranged in the corresponding The detection position is shown in FIG2 . It is worth noting that although the aforementioned spring pin connector can facilitate the assembly of the ECG main unit 3 into the assembly hole 215, since the connecting pins in the spring pin connector need to be elastically retractable, the transmission of ECG parameters (signals) is weakened to a certain extent, which is not conducive to the subsequent calculation and analysis of ECG signals in the ECG detection circuit board 312, and will lead to a reduction in the accuracy of the output results. However, the use of the spring pin connector to connect the ECG main unit 3 to the detection electrode bracket 2 allows the two to be embedded in an integral translational manner, ensuring a reliable electrical connection between the display device and each detection electrode while making the structure more compact. As can be seen from FIG12 , there are two aforementioned electrical adapter components 34, each located at the two end regions of the length of the main unit housing 311, so as to be able to electrically connect to the detection electrodes on the left and right parts of the detection electrode bracket respectively.

[0140] Specifically referring to Figure 13, a power supply battery 35 is also provided in the main housing 311, and the power supply battery 35 is electrically connected to the electrocardiogram detection circuit board 312 and the display screen assembly 322. It can be a rechargeable battery to further improve the portability of the corresponding electrocardiograph. Specifically, a corresponding charging interface 38 is constructed on the main housing 311, and the user charges the aforementioned power supply battery 35 through the charging interface 38; in a preferred embodiment, a display control circuit board 325 is provided in the display housing 321, and the power supply battery 35 is also electrically connected to the display control circuit board 325, and a power switch 36 is provided on the display housing 321, and the power switch 36 is used to control the power supply of the power supply battery 35. The user activates or stops the display device by pressing the power switch 36. In a specific embodiment, the aforementioned display control circuit board 325 can adopt an existing Android control mainboard. The control technology design of the Android control mainboard is relatively mature, and can enable the display device of the present invention to have more extended functions. For example, a camera module, a speaker module and a remote control module can be configured on the display control circuit board 325, so that the display device of the present invention can have the function of remote doctor diagnosis, thereby improving the intelligence level of the display device.

[0141] According to an embodiment of the present invention, a handheld portable electrocardiograph is provided, comprising a detection electrode holder 2 on which a plurality of detection electrodes are assembled, each detection electrode being arranged corresponding to an electrocardiograph detection target position, the detection electrode holder 2 comprising a holder body 21; the handheld portable electrocardiograph also comprises the aforementioned electrocardiograph host 3.

[0142] Referring to Figures 14 to 22, according to an embodiment of the present invention, specifically referring to Figure 14, a length-adjustable ECG detection electrode bracket arm is provided, comprising: a fixed arm segment 246, a first end of which is used for flippable connection with the bracket body 21 of the electrocardiograph, and a first detection electrode 241 is provided on the proximal surface of the fixed arm segment 246 (in a specific embodiment, the first detection electrode 241 corresponds to the V4 detection electrode in the twelve leads, and is described below as an example of the V4 detection electrode), and the fixed arm segment 246 also has a slide rail 2462 provided along its length extension direction. The aforementioned proximal surface refers to the side wall of the corresponding component facing the body of the user being detected when the electrocardiograph is in the ECG detection state, and the opposite side is the distal surface, that is, When the electrocardiograph is in the electrocardiograph detection state, the corresponding components are away from the side wall of the body of the user being detected; the telescopic arm section 247, the proximal surface of the telescopic arm section 247 is provided with a second detection electrode, the aforementioned second detection electrode is used to locate the midline position of the axillary area between the 3 / 4 ribs on the left side of the body of the detected user, corresponding to the twelve leads, the second detection electrode includes at least the V6 detection electrode 243, in a preferred embodiment, the second detection electrode also includes the V5 detection electrode 242, the telescopic arm section 247 where the second detection electrode is located also has a slider 2473, the slider 2473 can be slid along the length direction of the slide rail 2462 and mounted on the outer side of the slide rail 2462, so that the telescopic arm section 247 can be slidably and telescopically connected to the second end of the fixed arm section 246.

[0143] In this technical solution, on the one hand, the first end of the ECG detection electrode holder arm is connected to the holder body 21 in a flippable manner, so that the proximal surface of the holder arm can be opposite to the proximal surface of the holder body 21 after flipping, thereby achieving the goal of improving the compactness of the structure by folding and storing the holder arm, while forming physical protection for each detection electrode on the holder arm to prevent damage to the detection electrodes; on the other hand, based on the flippability of the holder arm, the holder arm is designed to be a retractable structure, so that the second detection electrode thereon (in a specific embodiment, the V6 detection electrode 243) can be adjusted and accurately positioned at the target position of different body shapes according to the different body shapes of users, thereby improving the accuracy of the ECG detection output results of the electrocardiograph.

[0144] As shown in FIG22 , in some embodiments, the slide rail 2462 has a wiring groove 24621 extending through both ends along its length. The wiring groove 24621 has a U-shaped cross-section, with the U-shaped opening facing the proximal side of the fixed arm section 246 and the telescopic arm section 247. The cables of the first detection electrode 241 and the second detection electrode respectively at least partially pass through the wiring groove 24621. In a specific embodiment, the width of the wiring groove 24621 is approximately 10 mm, and the cables of each detection electrode are routed within the wiring groove 24621. Because the slide rail 2462 is fixedly connected to the fixed arm section 246, its position relative to the fixed arm section 246 does not change during the telescopic adjustment of the telescopic arm section 247. Therefore, the cables are protected from wear and tear caused by friction during length adjustment.

[0145] Continuing with reference to Figure 22, a slide 24622 extending along the length direction of the slide rail 2462 is constructed on each of the two opposite side walls. The end of the slide 24622 away from the telescopic arm section 247 is a blind end, and the end of the slide 24622 close to the telescopic arm section 247 is an open end. A plurality of ball holes (not shown in the figure) are provided at positions corresponding to the slider 2473 and each of the slides 24622. The plurality of ball holes are spaced apart along the length direction of the slider 2473, and a ball (not shown in the figure) is clamped between each ball hole and the slide 24622.

[0146] In this technical solution, by clamping multiple balls between the slider 2473 and the slide rail 2462, the relative sliding process between the two can be made smoother, improving the convenience of length adjustment. It should be noted that the blind end of the aforementioned slide rail 24622 can limit the maximum retracted position of the slider 2473.

[0147] As a more preferred embodiment, the open end is provided with a limiting hole 24624, and a limiting part (such as a limiting pin with interference fit or a limiting stud with threaded connection, etc.) is connected inside the limiting hole 24624 to limit the maximum extension position of the telescopic arm section 247 by contacting the side of the slider 2473 away from the fixed arm section 246. In this way, the aforementioned open end not only realizes the ball assembly so that the slider 2473 is slidably connected with the slide rail 2462, but also realizes the purpose of limiting the maximum extension position of the slider 2473 through the limiting part, and the structure is simple.

[0148] 15 and 22 , the slide rail 2462 has a positioning ridge 24623 on its wall surface facing away from the wiring groove 24621, and the positioning ridge 24623 has a plurality of positioning protrusions 246231. The plurality of positioning protrusions 246231 are arranged at intervals along the length direction of the positioning ridge 24623. The fixed arm section 246 includes a first fixed shell 24631 and a second fixed shell 24632 assembled with each other along the width direction of the fixed arm section 246. A clamping gap (not marked in the figure) is formed between the first fixed shell 24631 and the second fixed shell 24632. Positioning grooves (not shown in the figure) corresponding to the respective positioning protrusions 246231 are formed on the opposite walls of the clamping gap. The positioning ridge 24623 is clamped in the clamping gap and the respective positioning protrusions 246231 are respectively located in the respective positioning grooves.

[0149] In this technical solution, the fixed arm section 246 is formed by assembling and combining the first fixed shell 24631 and the second fixed shell 24632, which can be beneficial to the structural design at the first end position and help reduce the manufacturing and processing difficulty of the fixed arm section 246. At this time, the positioning protrusion 24623 on the slide rail 2462 can be clamped in the clamping gap formed between the first fixed shell 24631 and the second fixed shell 24632 during the assembly process of the two, and pre-positioned by the positioning protrusion 246231 and the positioning groove, so that a fixed connection is formed between the slide rail 2462 and the fixed arm section 246, while facilitating the assembly of the three scattered components and reducing the assembly difficulty.

[0150] On the basis of the aforementioned pre-positioning, the slide rail 2462 is constructed with positioning holes 24625 on the two side walls of the slide rail 24622, and the first fixed shell 24631 and the second fixed shell 24632 are respectively bolted to the positioning holes 24625 by threaded parts (such as screws).

[0151] That is, the slide rail 2462 in the present invention forms a primary positioning with the first fixed shell 24631 and the second fixed shell 24632 through the positioning protrusions on the one hand, and forms a secondary positioning through the screw parts on the other hand, thereby ensuring the position reliability of the slide rail 2462 and further ensuring the smooth telescopic adjustment of the telescopic arm section 247.

[0152] The fixed arm section 246 further includes a first electrode shell 2464 . The first detection electrode 241 is located on the proximal surface of the first electrode shell 2464 . The first electrode shell 2464 is detachably connected to the proximal surfaces of the first fixed shell 24631 and the second fixed shell 24632 .

[0153] That is, in this technical solution, the first electrode shell 2464 is formed and assembled independently of other components in the fixed arm segment 246, which can facilitate the integrated forming of the detection electrode. At this time, the first fixed shell 24631 and the second fixed shell 24632 serve as one of the connecting components of the flip connection on the one hand, and as an assembly carrier of the first electrode shell 2464 on the other hand.

[0154] Specifically referring to Figure 18, the telescopic arm section 247 also includes a second electrode shell 2474, the second detection electrode is located on the proximal surface of the second electrode shell 2474, and the cross-section of the slider 2473 is U-shaped, the U-shaped opening of the slider 2473 faces the second electrode shell 2474 and is connected to the distal surface of the second electrode shell 2474, and the slider 2473 with a U-shaped cross-section is inverted on the three outer surfaces of the slide rail 2462, which can ensure the stability and reliability of the sliding connection between the slider 2473 and the slide rail 2462.

[0155] In a preferred embodiment, the electrode column barrel of the first detection electrode 241 is integrally formed with the first electrode shell 2464, and the electrode column barrel (not labeled in the figure) of each second detection electrode is integrally formed with the second electrode shell 2474. The integrally formed electrode column barrels do not require a specific assembly process, thereby improving the assembly efficiency of the individual detection electrodes.

[0156] 15 and 19 , in some embodiments, a first through hole (not labeled in the figure) is formed at the end of the first fixed shell 24631 corresponding to the first end, and a second through hole (not labeled in the figure) is formed at the end of the second fixed shell 24632 corresponding to the first end. A flange ring 246311 is formed on the side opening of the first through hole away from the second fixed shell 24632. The flange ring 246311 can form a rotating shaft connection with the corresponding connecting ear seat on the bracket body 21, and the cables of the first detection electrode 241 and the second detection electrode can be led out through the hollow structure corresponding to the flange ring 246311 and the first through hole, thereby simplifying the structural design of the electrocardiograph.

[0157] As shown in FIG19 , a rotating shaft assembly 2465 is assembled in the second through hole. The rotating shaft assembly 2465 includes a rotating shaft 24651. The rotating shaft 24651 has a connecting portion 246511. The connecting portion 246511 is used to be detachably connected to the bracket body 21. The connecting portion 246511 has an extended connection position protruding from the outside of the opening of the second through hole and a retracted insertion position hidden inside the opening of the second through hole. In this technical solution, the rotating shaft assembly 2465 is used to realize the rotatable connection between the second fixed shell 24632 and the corresponding connecting ear seat of the bracket body 21. In combination with the above, the first fixed shell 24631 can form a rotating shaft connection with the corresponding connecting ear seat on the bracket body 21 through the flange ring 246311. In this way, the two together realize the flipping function of the ECG detection electrode bracket arm. As shown in Figure 14, the aforementioned connecting part 246511 is specifically a plate structure with a connecting hole on it, and the ear seat connected to it is correspondingly constructed with a corresponding straight groove (not shown in the figure). The ear seat is a shell structure with an internal space. When the bracket arm is assembled, force is applied to the connecting part 246511 to put it in the retracted insertion position. At this time, the first end of the bracket arm can be inserted into the gap space between the two ear seats, and the flange ring 246311 can be rotatably inserted into the ear seat through hole on one side. After the rotation of the rotating shaft assembly 2465 is coaxial with the ear seat through hole, the connecting part 246511 switches from the retracted insertion position to the extended connection position, that is, the connecting part 246511 will extend into the aforementioned straight groove. At this time, the position of the connecting part 246511 can be fixed on the inner side of the bracket body 21. It can be understood at this time that the second fixing shell 24632 can rotate relative to the rotating shaft assembly 2465. In this technical solution, the position switching of the connecting portion 246511 allows the bracket arm to be assembled independently of the bracket body 21, and then its first end can be reassembled with the bracket body 21 as an integral whole. It is only necessary to connect the connecting portion 246511 to the bracket body 21. The retractable connecting portion 246511 can reduce the gap between the bracket arm and the ear seat after assembly, thereby improving the appearance consistency.

[0158] Further referring to Figure 19, the rotating shaft assembly 2465 is rotatably connected to the second fixed shell 24632 through the following structure, the rotating shaft assembly 2465 also includes an outer cylinder 24652 fixedly connected to the second fixed shell 24632, the rotating shaft 24651 is coaxially connected to the outer cylinder 24652 so as to be axially movable, and a spiral elastic member 24653 is provided on the outer side of the rotating shaft 24651, one end of the spiral elastic member 24653 is fixedly connected to the outer cylinder 24652, and the other end of the spiral elastic member 24653 is fixedly connected to the rotating shaft 24651.

[0159] In this technical solution, the aforementioned spiral elastic member 24653 can, on the one hand, provide a reverse elastic force to the rotation of the rotating shaft 24651, so that the bracket arm has a pre-loaded force to bring its proximal surface close to the proximal surface of the bracket body 21, and this force can make the various detection electrodes on the bracket arm reliably contact the human body during the electrocardiogram detection process, thereby ensuring the electrocardiogram detection effect; on the other hand, the aforementioned spiral elastic member 24653 also has an axial compression rebound force, and this compression rebound force can jointly drive the axial movement of the connecting part 246511 (that is, the rotating shaft 24651) with the external force applied by the user, thereby realizing the switching between the aforementioned extended connection position and the retracted insertion position. Specifically, the aforementioned rotating shaft 24651 has a small-diameter shaft end, which is inserted into the through hole on the bottom of the outer cylinder 24652, and the displacement of one side of the small-diameter shaft end is limited by the gasket 24654 and the screw 24655. The aforementioned rotating shaft 24651 also has a large-diameter shaft end, and the spiral elastic member 24653 is clamped between the end face of the large-diameter shaft end and the bottom of the outer cylinder 24652. In this way, when the user applies external force to the connecting part 246511 to compress the spiral elastic member 24653, the connecting part 246511 will move close to the bottom of the cylinder and then retract into the second through hole to realize the position switching of the connecting part 246511. Conversely, after the external force is released, the connecting part 246511 is extended from the aforementioned retracted insertion position to the extended connection position under the action of the restoring force of the spiral elastic member 24653.

[0160] As shown in FIG14 , a fixed section panel 2466 is connected to the distal surface of the fixed arm section 246 , and a telescopic section panel 2475 is connected to the distal surface of the telescopic arm section 247 , so as to enhance the overall aesthetics of the bracket arm.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above are merely preferred embodiments of the present invention.
