Background

Electrocardiography (ECG) is a technique that uses an electrocardiograph to record from the body surface the pattern of electrical activity changes produced by each cardiac cycle of the heart.

Detailed Description

The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.

A typical six lead ecg monitoring device 100 employing a right leg drive circuit typically requires four electrodes for connecting to different parts of the body. At present, four electrodes (including a right leg driving electrode) in six-lead electrocardiogram monitoring equipment are arranged on a front shell or a rear shell, the electrodes are close to each other, and the right leg driving electrode is easily influenced by other electrodes to vibrate during monitoring, so that the stability of ECG signals is influenced, and the monitoring result is inaccurate. To solve this problem, please refer to fig. 1, the present embodiment provides an electrocardiograph monitoring apparatus 100.

Referring to fig. 1 to 3 together, an electrocardiograph monitoring apparatus 100 according to an embodiment of the present disclosure includes a first housing 10, a second housing 20, a middle frame 30, a first electrode 42, a second electrode 44, a third electrode 46, and a fourth electrode 48. The middle frame 30 includes a first side 31 and a second side 33 opposite to each other, the first case 10 is mounted on the first side 31 of the middle frame 30, and the second case 20 is mounted on the second side 33 of the middle frame 30. The first electrode 42 is disposed on the first shell 10 or the second shell 20, and corresponds to the first area 101 of the electrocardiograph monitoring device 100, and the first area 101 is an area corresponding to the left hand when the electrocardiograph monitoring device 100 is held. The second electrode 44 is disposed on the first shell 10 or the second shell 20 and corresponds to the second area 102 of the electrocardiograph monitoring device 100, and the second area 102 is an area corresponding to the right hand when the electrocardiograph monitoring device 100 is held. Optionally, there is a certain spacing between the second region 102 and the first region 101. The third electrode 46 is provided on the middle frame 30 and serves as a right leg driving electrode. The fourth electrode 48 is provided to the first case 10 or the second case 20, and the first electrode 42, the second electrode 44, the third electrode 46, and the fourth electrode 48 are insulated from each other.

The electrocardiograph monitoring device 100 may be a portable electrocardiograph monitoring device 100, in particular, a handheld electrocardiograph monitoring device 100, which may be a health measurement product used in a home, a trip, or a traditional hospital. When a user uses the electrocardiograph monitoring device 100 of the present application to perform electrocardiograph monitoring, the user holds the electrocardiograph monitoring device 100 with two hands, specifically, the left hand corresponds to the first region 101 and contacts with the first electrode 42, the right hand corresponds to the second region 102 and contacts with the second electrode 44, one of the fingers of the left hand or the right hand contacts with the third electrode 46, and the left leg (left side of the body, position below the abdomen) contacts with the fourth electrode 48, thereby realizing six-lead electrocardiograph monitoring. In one embodiment, the "first region 101" and the "second region 102" may be divided by an axis 001 of the electrocardiographic monitoring device 100 when the user normally uses the device, "the first region 101" is a region on the left of the axis 001 when the user normally uses the device, and "the second region 102" is a region on the right of the axis 001 when the user normally uses the device.

More specifically, the third electrode 46 is used as a right leg driving electrode for improving the common mode rejection ratio of the ECG signal collected by the electrocardiograph monitoring device 100, so as to reduce the amplitude of the common mode interference signal in the collected ECG signal, and greatly reduce the interference on the human body as an antenna. The left-hand contacted first electrode 42 and the right-hand contacted second electrode 44 form an ECG I lead signal acquisition, the left-leg contacted fourth electrode 48 and the right-hand contacted second electrode 44 form an ECG II lead signal acquisition, and then the remaining 4 lead electrode signals are derived from the I lead signal and the II lead signal in the following way: the III lead signal is II lead signal-I lead signal; aVR ═ II lead signal + I lead signal)/2, aVL ═ I lead signal-II lead signal/2, aVF ═ II lead signal-I lead signal/2, and further, all of the 6 lead signals are acquired.

The utility model provides an electrocardio monitoring facilities 100 locates first shell 10 or second shell 20 with first electrode 42, first shell 10 or second shell 20 are also located to second electrode 44, and locate center 30 and regard as right leg drive electrode with third electrode 46, compare in all setting up four electrodes at first shell 10 or second shell 20, can make the distance between first electrode 42 and the right leg drive electrode, and the distance between second electrode 44 and the right leg drive electrode is all drawn greatly, right leg drive electrode is difficult to receive the influence of first electrode 42 or second electrode 44 and takes place the vibration during the monitoring, with the stability of guaranteeing ECG signal, and then guarantee the accuracy of monitoring result.

In some embodiments, the first shell 10 can comprise a glass shell, the second shell 20 can also comprise a glass shell, and the first electrode 42 and the second electrode 44 comprise indium tin oxide electrodes or metal electrodes disposed within the glass shell.

At present, most of the electrocardiogram monitoring devices on the market adopt stainless steel as electrodes, four stainless steel electrodes are respectively connected with different parts of a human body, and the four electrodes need to be completely and independently separated, so that the whole appearance of the electrocardiogram monitoring devices is usually divided by the stainless steel electrodes, and the appearance is lack of attractiveness. Of course, a silicon carbon nitrogen film plated on a shell is also adopted as an electrode in the market, but the color of the silicon carbon nitrogen film is darker, and the overall appearance is not beautiful enough.

In order to solve the problem of poor appearance, in one embodiment, the first casing 10 is made of glass, the second casing 20 is also made of glass, and the first electrode 42 and the second electrode 44 are both Indium Tin Oxide (ITO) electrodes disposed inside the first casing 10 and each include a plurality of strips. The first shell 10 is made of a glass material, the second shell 20 is also made of a glass material, and the first electrode 42 and the second electrode 44 both adopt transparent ITO electrodes, so that compared with the dark color of a chromium-plated silicon carbon nitrogen film, the electrocardiogram monitoring device 100 is relatively transparent and has a relatively beautiful appearance. Moreover, a plurality of the first electrodes 42 or the second electrodes 44 are electrically connected to each other, and an interval exists between two adjacent electrodes, so that the first electrodes 42 or the second electrodes 44 do not have a separation feeling like a plurality of stainless steel electrodes, and the appearance of the electrocardiograph monitoring device 100 is more beautiful.

In one example, the ITO electrode as the first electrode 42 may be completely embedded in the first case 10, and only one electrical contact may be exposed to electrically connect to another component, and the ITO electrode as the second electrode 44 may be completely embedded in the first case 10, and only one electrical contact may be exposed to electrically connect to another component. In this way, the first electrode 42 and the second electrode 44 can be prevented from being exposed to the outside and often rubbing against an external object to cause fracture, thereby influencing the acquisition of the ECG signal. Of course, the ITO electrode as the first electrode 42 may be disposed on the outer surface or the inner surface of the first case 10 by a plating method, and similarly, the ITO electrode as the first electrode 42 may also be disposed on the outer surface or the inner surface of the first case 10 by a plating method. The first electrode 42 and the second electrode 44 are processed on the surface of the first shell 10 in a film coating manner, the processing technology is simple and convenient, and the production efficiency can be improved.

It is understood that in other embodiments, the first shell 10 may be a shell made of other materials, such as plastic. Similarly, the second casing 20 may be a casing made of other materials, such as plastic. The first shell 10 and/or the second shell 20 being made of plastic can reduce the weight of the electrocardiograph monitoring device 100 and is more portable. In the case that the first shell 10 is made of other materials, the first electrode 42 may be an ito electrode or a metal electrode; the second electrode 44 may be an indium tin oxide electrode or a metal electrode. Similarly, in the case that the second shell 20 is a shell made of other materials, the first electrode 42 can be an ito electrode, and can also be a metal electrode; the second electrode 44 may be an indium tin oxide electrode or a metal electrode.

With continuing reference to fig. 1-3, in some embodiments, the first electrode 42 and the second electrode 44 are disposed on the first housing 10 and are symmetrically disposed about a central axis 001 of the ecg monitoring device 100. When a user holds the electrocardiograph monitoring device 100 with two hands, the first housing 10 can be aligned to the user in a manner similar to a manner of holding a mobile phone with a game, the thumb of the left hand contacts the first electrode 42 of the first region 101, the thumb of the right hand contacts the second electrode 44 of the second region 102, and the index finger of the left hand contacts the third electrode 46 on the middle frame 30, so that the user can hold the electrocardiograph monitoring device conveniently and ergonomically. At this time, the fourth electrode 48 may be disposed on the second case 20, and since the fourth electrode 48 is apart from the first and second electrodes 42 and 44, contact with the left leg is also facilitated.

In some embodiments, the first electrode 42 and the second electrode 44 are disposed on the second housing 20 and are symmetrically disposed about a central axis 001 of the electrocardiograph monitoring device 100. When a user holds the electrocardiograph monitoring device 100 with two hands, the user can hold the mobile phone in a manner similar to playing games, the second housing 20 can be opposite to the user, the thumb of the left hand contacts the first electrode 42 of the first region 101, the thumb of the right hand contacts the second electrode 44 of the second region 102, and the index finger of the left hand contacts the third electrode 46 on the middle frame 30, so that the holding is very convenient and meets ergonomics. At this time, the fourth electrode 48 may be disposed on the first case 10, and since the fourth electrode 48 is apart from the first electrode 42 and the second electrode 44, contact with the left leg is also facilitated.

In some embodiments, one of the first electrode 42 and the second electrode 44 is disposed on the first shell 10 and the other is disposed on the second shell 20, and the projections of the first electrode 42 and the second electrode 44 coincide. At this time, the first region 101 and the second region 102 overlap. In one example, the first electrode 42 is disposed on the first housing 10, the second electrode 44 is disposed on the second housing 20, and when the user holds the electrocardiograph monitoring device 100 with two hands, the first housing 10 can be directly opposite to the user, the thumb of the right hand contacts the first electrode 42, the index finger of the left hand contacts the second electrode 44, and the thumb of the left hand or the index finger of the right hand contacts the third electrode 46 on the middle frame 30. At this time, the fourth electrode 48 may be disposed on the second case 20, and since the fourth electrode 48 is away from the first electrode 42, contact with the left leg is also facilitated. In another example, the first electrode 42 is disposed on the second shell 20, the second electrode 44 is disposed on the first shell 10, and when the user holds the electrocardiograph monitoring device 100 with two hands, the second shell 20 can be directly opposite to the user, the thumb of the left hand contacts the first electrode 42, the index finger of the right hand contacts the second electrode 44, and the index finger of the left hand or the thumb of the right hand contacts the third electrode 46 on the middle frame 30, so that the holding is very convenient and ergonomic. At this time, the fourth electrode 48 may be disposed on the first case 10, and since the fourth electrode 48 is away from the first electrode 42, contact with the left leg is also facilitated. Of course, the holding manner of the user when holding the electrocardiographic monitoring device 100 with two hands is not limited to the above example, as long as the requirement that the left hand contacts the first electrode 42, the right hand contacts the second electrode 44, one finger of the left hand or the right hand contacts the third electrode 46, and the left leg contacts the fourth electrode 48 can be met, so as to implement six-lead electrocardiographic monitoring.

In addition, the projection coincidence of the first electrode 42 and the second electrode 44 includes: in a projection plane approximately parallel to the surface of the first shell 10 or the second shell 20, the projection range of the first electrode 42 and the projection range of the second electrode 44 completely overlap, so that on one hand, a good appearance can be maintained, and on the other hand, when a user holds the electronic device, the finger extension lengths of two hands are approximately the same, and the holding experience is better. Or, the projection range of the first electrode 42 in the projection plane includes the projection range of the second electrode 44, and the center of the projection range of the first electrode 42 coincides with the center of the projection range of the second electrode 44, and similarly, this design can ensure that the finger extension lengths of both hands are substantially the same when the user grips, and the grip experience is better. Or, the projection range of the second electrode 44 in the projection plane includes the projection range of the first electrode 42, and the center of the projection range of the first electrode 42 coincides with the center of the projection range of the second electrode 44, and similarly, this design can ensure that the finger extension lengths of both hands are substantially the same when the user grips, and the grip experience is better. Or, the projection range of the first electrode 42 includes the projection range of the second electrode 44 in the projection plane, and the center of the projection range of the first electrode 42 is staggered from the center of the projection range of the second electrode 44, so that the first electrode 42 is closer to the left hand or the right hand, and the second electrode 44 is closer to the right hand or the left hand, which can further improve the holding experience. Or, the projection range of the second electrode 44 includes the projection range of the first electrode 42 in the projection plane, and the center of the projection range of the first electrode 42 is staggered from the center of the projection range of the second electrode 44, so that the first electrode 42 is closer to the left hand or the right hand, and the second electrode 44 is closer to the right hand or the left hand, which can further improve the holding experience.

It is understood that in the case that one of the first electrode 42 and the second electrode 44 is disposed on the first shell 10, and the other is disposed on the second shell 20, the projections of the first electrode 42 and the second electrode 44 may also be misaligned, and the projections of the first electrode 42 and the second electrode 44 may be disposed in a staggered manner, for example, the first electrode 42 is disposed closer to the left hand or the right hand, and the second electrode 44 is disposed closer to the right hand or the left hand, so as to further enhance the experience of holding.

Referring to fig. 3, in some embodiments, the middle frame 30 is made of a conductive material, and the middle frame 30 is integrally formed as the third electrode 46. Specifically, the middle frame 30 may be made of stainless steel or Aluminum (AL) alloy. The whole middle frame 30 serves as the third electrode 46, so that when a user holds the electrocardiograph monitoring device 100, the user can hold any position on the middle frame 30 to realize contact with the third electrode 46, fingers do not need to be placed at a specified position on the middle frame 30, and the holding operation is more convenient.

In some embodiments, the middle frame 30 includes an electrode region 32, and the third electrode 46 includes an indium tin oxide electrode or a metal electrode disposed on the electrode region 32. In this case, the middle frame 30 may be made of a non-conductive material, such as plastic, which may reduce the cost of the electrocardiograph monitoring apparatus 100 and reduce the weight of the electrocardiograph monitoring apparatus 100.

In one example, the electrode region 32 protrudes compared to the sidewall 34 of the bezel 30. At this time, the protruded electrode region 32 has a function of positioning guide, and can guide the user to press a finger thereon to achieve the acquisition of the lead signal.

In another example, the electrode region 32 is recessed compared to the sidewall 34 of the middle frame 30. At this time, the recessed electrode region 32 has a positioning guide function, and can guide the user to press a finger thereon to realize the acquisition of the lead signal.

In yet another example, the electrode area 32 is uniform compared to the sidewall 34 of the middle frame 30, and the electrode area 32 is provided with a mark. Wherein, the electrode region 32 is consistent with the sidewall 34 of the middle frame 30: the electrode region 32 is neither protruded nor recessed compared to the sidewall 34 of the middle frame 30, but forms a smoothly connected structure with the surrounding sidewall 34. The mark includes, but is not limited to, a figure, a word, a pattern, or some concave-convex structure, etc., as long as the function of positioning guidance can be achieved visually or tactually. The mark setting also has the function of positioning guide, and can guide the user to press the finger on the mark setting to realize the acquisition of the lead signal.

Referring to fig. 1 and 3, in some embodiments, the middle frame 30 may be provided with the key 36, and the third electrode 46 includes an ito electrode or a metal electrode provided on the key 36. The buttons 36 may be buttons 36 that function as power on, power off, selection, adjustment, and the like. The key 36 may protrude from the side wall 34 of the middle frame 30, may be recessed from the middle frame 30, or may not protrude from or be recessed from the middle frame 30 (in this case, a mark may be disposed on the key 36). At this time, the key 36 not only can perform the original functions of power on, power off, selection, or adjustment, but also can perform the positioning and guiding functions.

Referring to fig. 2, in some embodiments, when the middle frame 30 includes the electrode area 32 and the third electrode 46 is disposed on the electrode area 32, the electrocardiograph monitoring device 100 further includes an upper half 103 and a lower half 104, the first electrode 42 and the second electrode 44 are disposed on the lower half 104, and the third electrode 46 and the fourth electrode 48 are disposed on the upper half 103. In this manner, the user may more easily contact the first electrode 42 with the left hand, the second electrode 44 with the right hand, the right leg electrode actuation with the third electrode 46 or the right hand, and the left leg with the fourth electrode 48 while holding the electrocardiographic monitoring device 100. The "upper half 103" and the "lower half 104" may be defined by the other axis 002 of the electrocardiographic monitoring device 100 when the user normally uses the device, the "upper half 103" is an area above the axis 002 when the user normally uses the device, and the "lower half 104" is an area below the axis 002 when the user normally uses the device.

In some embodiments, when the middle frame 30 includes the electrode region 32 and the third electrode 46 is disposed on the electrode region 32, the distance between the center of the third electrode 46 and the center of the second region 102 is greater than or equal to the distance between the center of the third electrode 46 and the center of the first region 101. Thus, the third electrode 46 (left index finger contact) can be far away from the second electrode 44 (right thumb contact), and the right leg driving electrode is less susceptible to the influence of the first electrode 42 or the second electrode 44 and vibrates during monitoring, so as to ensure the stability of the ECG signal and further ensure the accuracy of the monitoring result.

Referring to fig. 3 and 4, in some embodiments, the middle frame 30 includes an electrode area 32, the third electrode 46 is disposed in the electrode area 32, and the first shell 10, the second shell 20, and the middle frame 30 form a receiving space 106. The electrocardiograph monitoring device 100 may also include a motherboard 50 and one or more processors 60. The main board 50 is accommodated in the accommodating space 106. The processor 60 is mounted to the motherboard 50. The first electrode 42, the second electrode 44, the third electrode 46 and the fourth electrode 48 are all electrically connected to the processor 60, and the processor 60 is configured to acquire at least one electrical signal of the first electrode 42, the second electrode 44, the third electrode 46 and the fourth electrode 48, and process the acquired electrical signal according to the aforementioned manner to obtain a 6-lead signal, so as to obtain an electrocardiogram. The main board 50 may be mounted on the middle frame 30, and the main board 50 includes a hard circuit board, a flexible circuit board, or a rigid-flex circuit board. Of course, in other embodiments, the processor 60 may also be disposed on the middle frame 30 and electrically connected to the circuit board.

With continued reference to fig. 3 and 4, in some embodiments, the electrocardiograph monitoring apparatus 100 may further include a bracket 70, the main board 50 is mounted on the bracket 70, and the bracket 70 is mounted on the middle frame 30, so that the main board 50 is indirectly mounted on the middle frame 30.
