Technical Field

[0001] This application relates to the field of electrocardiogram and blood pressure detection equipment technology, and more particularly to an electrocardiogram blood pressure monitor. Background Technology

[0002] Heart rhythm abnormalities are a common condition that can be accurately diagnosed by measuring the patient's electrocardiogram (ECG). For portable ECG blood pressure monitors, during ECG testing, the patient typically holds the monitor, with both hands in contact with the electrodes on either side of the monitor, allowing the ECG to be measured via these electrodes.

[0003] Because it uses a single-electrode configuration, with one set of electrodes on each side, the system identifies the information collected by the electrodes as the patient's electrocardiogram (ECG) data. However, in practical applications, interference such as noise can easily cause abnormalities in the detected ECG signals, affecting the accuracy of the ECG test results. Utility Model Content

[0027] To address the problem of inaccurate output results due to noise interference during ECG monitoring using single-electrode pads in existing technologies, this application provides an ECG blood pressure monitor. By dividing the contact point into measuring electrodes and driving electrodes, with each measuring electrode equipped with a driving electrode, a localized and efficient common-mode interference suppression loop is formed. This structure helps provide a more direct and stable reference for each measuring channel, thereby improving the overall common-mode suppression capability and anti-interference performance of the system. Furthermore, during patient use, the driving circuit corrects the detected ECG information to obtain accurate ECG data and output a corresponding ECG, facilitating diagnosis and treatment by medical personnel to determine if the patient's heart rhythm is abnormal.

[0028] Please see Figure 1 This application provides an electrocardiogram blood pressure monitor, including: a housing 1, and two sets of contact points 2 disposed on both sides of the housing 1. Each contact point 2 includes: a measuring electrode 21 and a driving electrode 22. The measuring electrode 21 and the driving electrode 22 are disposed close to each other, and the driving electrodes 22 of the two sets of contact points 2 are connected to the same driving circuit.

[0029] When using an electrocardiogram (ECG) blood pressure monitor to detect a patient's electrocardiogram (ECG), the patient holds the monitor with both hands, ensuring that both hands are in contact with the contact points 2 on both sides of the housing 1. Because the measuring electrode 21 and the driving electrode 22 are positioned close to each other, the patient can simultaneously touch both electrodes with the same finger. In the embodiment provided in this application, the ECG is detected using the measuring electrode 21, and a common-mode interference suppression circuit is formed between the driving electrode 22 and the measuring electrode 21. This helps provide a more direct and stable reference for the measuring channel 21, thereby improving the overall common-mode suppression capability and anti-interference performance of the system. Furthermore, when the patient uses the monitor, the driving circuit 22 corrects the detected ECG information to obtain accurate ECG data and output a corresponding ECG, facilitating diagnosis and treatment by medical personnel to determine if the patient's heart rhythm is abnormal.

[0030] In the embodiments provided in this application, since the measuring electrode 21 and the driving electrode 22 are positioned close to each other, patients can easily touch both the measuring electrode 21 and the driving electrode 22 simultaneously with one finger. This allows for accurate detection and identification of the patient's heart rhythm via the common-mode interference suppression circuit formed between the driving electrode 22 and the measuring electrode 21, effectively preventing interference from noise from affecting the accuracy of the ECG information detected by the measuring electrode 21. Simultaneously, since the measuring electrode 21 and the driving electrode 22 are located on the same plane of the housing 1, the space occupied on other sides of the housing 1 can be effectively reduced, allowing for a thinner and lighter design of the housing 1, thereby improving the overall portability of the ECG blood pressure monitor. Specifically, in some embodiments, since the measuring electrode 21 and the driving electrode 22 are located on the same plane of the housing 1, the housing 1 can be designed in a flat shape, giving the ECG blood pressure monitor a tablet-like structure. This results in a thinner and lighter overall structure, allowing the user to easily touch both the measuring electrode 21 and the driving electrode 22 simultaneously with one finger, facilitating handheld ECG blood pressure monitoring for ECG testing.

[0031] In some embodiments, to facilitate the use of the ECG blood pressure monitor by users, the shape of the housing 1 can be designed as a tablet computer, smartwatch, handle, or other similar style, so that users can choose an ECG blood pressure monitor with the appropriate housing shape according to their own needs and usage habits.

[0032] In the embodiments provided in this application, the overall structure of the contact point 2 formed by the measuring electrode 21 and the driving electrode 22 can be set to be the same size or similar to that of a single electrode sheet in the prior art. This makes the space occupied by the contact point 2 as a whole in the electrocardiogram blood pressure monitor similar to that of the electrode sheet in the prior art, effectively reducing the overall space occupation. Dividing the original electrode sheet into the measuring electrode 21 and the driving electrode 22, a common-mode interference suppression circuit is formed between the driving electrode 22 and the measuring electrode 21. This helps to provide a more direct and stable reference for the measuring channel 21. Furthermore, when the patient is being tested, the common-mode interference suppression circuit can play an anti-interference role, thereby obtaining accurate electrocardiogram information of the patient and outputting the corresponding electrocardiogram. This facilitates medical staff in providing a basis for diagnosis and treatment of whether there are abnormalities in the patient's electrocardiogram information.

[0033] In some optional embodiments, a gap 23 is provided between the measuring electrode 21 and the driving electrode 22, preventing them from contacting each other. By providing a gap 23 between the measuring electrode 21 and the driving electrode 22, interference and other abnormalities caused by contact between the measuring electrode 21 and the driving electrode 22 are avoided while keeping them as close as possible, effectively improving the overall safety and stability of the operation.

[0034] In some optional embodiments, an insulating isolator 24 is provided between the measuring electrode 21 and the driving electrode 22. The insulating isolator 24 isolates the measuring electrode 21 and the driving electrode 22, effectively preventing crosstalk between the electrical signals of the measuring electrode 21 and the driving electrode 22. This allows the internal system of the driving circuit to calculate and correct the ECG signal detected by the measuring electrode 21 through a common-mode interference suppression circuit, thereby obtaining accurate ECG information data. This facilitates medical personnel in judging the patient's heart rhythm using the ECG formed from the patient's ECG information data, thereby improving the accuracy of diagnosing the patient's condition.

[0035] In some alternative embodiments, the two sets of contact points 2 are symmetrically arranged about the central axis of the housing 1, so that when the patient uses the electrocardiogram blood pressure monitor, he / she can easily contact the contact points 2 on both sides to form a circuit, so as to detect and acquire the patient's electrocardiogram information through the measuring electrodes 21 of the contact points 2.

[0036] In some optional embodiments, the measuring electrode 21 and the driving electrode 22 in each set of contact points 2 are integrated into a unified component. By integrating the measuring electrode 21 and the driving electrode 22, the relative distance between the measuring electrode 21 and the driving electrode 22 can be brought as close as possible, thereby facilitating simultaneous contact with both the measuring electrode 21 and the driving electrode 22 using the same finger, and thus improving the anti-interference capability of the detection data while detecting the patient's electrocardiogram information.

[0037] In some optional embodiments, the driving electrodes 22 in the two sets of contact points 2 are connected in parallel to the output terminal of the same driving circuit. The driving electrodes 22 of the two sets of contact points 2 are directly connected in parallel in the driving circuit inside the housing 1, thereby jointly forming a driving reference surface with lower impedance and greater redundancy. Therefore, even if the contact effect of one driving electrode 22 is poor, the other driving electrode 22 can maintain the system function, significantly improving the robustness and success rate of the measurement.

[0038] In some optional embodiments, a safety current-limiting resistor is connected in series at the output of the drive circuit to limit the current magnitude, so that the current will not cause discomfort to the patient and improve the comfort and safety of the use process.

[0039] In some optional embodiments, anti-slip structures are provided on the measuring electrode 21 and the driving electrode 22, respectively. By providing anti-slip structures on the measuring electrode 21 and the driving electrode 22, when the patient's hand or fingers come into contact with the measuring electrode 21 and the driving electrode 22, the tactile feedback provided by the anti-slip structures allows the patient to know whether they are correctly pressing on the contact point 2, ensuring that the ECG blood pressure monitor can accurately acquire the patient's ECG information data. Simultaneously, by providing anti-slip structures, the patient's hand or fingers can be prevented from slipping off the measuring electrode 21 or the driving electrode 22, ensuring that the patient's hand only contacts one set of electrode pads on the measuring electrode 21 or the driving electrode 22, or completely detaches from the contact point 2, thereby affecting the continuous detection effect of the ECG blood pressure monitor on the patient's ECG information.

[0040] In some optional embodiments, the anti-slip structure adopts a raised dot structure or a textured structure. The raised dot structure consists of a plurality of raised dots arranged in an array on the measuring electrode 21 and the driving electrode 22. When the patient being tested comes into contact with the raised dot structure, the undulation state on the measuring electrode 21 and the driving electrode 22 can be clearly perceived. At the same time, the raised dots in the raised dot structure can increase the contact area between the measuring electrode 21 and the driving electrode 22 and the patient's hand, so that the measuring electrode 21 or the driving electrode 22 can stably acquire the patient's electrocardiogram information, and can effectively increase the friction, thereby achieving a stable and reliable anti-slip effect.

[0041] The ridges on the textured structure can be straight segments or wavy patterns, which facilitates clear tactile feedback when the patient comes into contact with the textured structure. Compared to the parallel straight segments of the textured structure, the wavy pattern can provide anti-slip effect in four directions: front, back, left, and right, thereby effectively preventing the patient's hand or fingers from slipping off the measuring electrode 21 or the driving electrode 22.

[0042] In some optional embodiments, the contact point 2 is located on the front or back of the housing 1. A display screen 11 is provided on the housing 1, the display screen 11 is located on the front of the housing 1, and the display screen 11 is electrically connected to a drive circuit disposed inside the housing 1.

[0043] When contact point 2 is located on the front of housing 1, i.e., on the same plane as display screen 11, it allows patients to clearly see whether their hand is effectively contacting contact point 2 when using the ECG blood pressure monitor for ECG information detection. Simultaneously, the corresponding ECG information detection data can be read instantly on display screen 11. During continuous ECG information detection, the patient's heart rate value can be displayed on display screen 11 in the form of an electrocardiogram (ECG), allowing patients and medical staff to determine whether there are any abnormalities in the patient's heart rate and other ECG information based on the ECG.

[0044] When contact point 2 is located on the back of housing 1, i.e., opposite to the display screen 11, the screen-to-body ratio of the display screen 11 on housing 1 can be maximized. This allows patients and medical staff, especially older patients or those with poor vision, to clearly see the detected heart rate value and corresponding electrocardiogram displayed on the display screen 11. Simultaneously, it reduces the overall size of housing 1, further improving the portability of the electrocardiogram and blood pressure monitor. This makes it easier for patients to carry it with them and perform corresponding electrocardiogram monitoring at any time, thereby monitoring changes in the patient's daily heart rate and other electrocardiogram information.

[0045] In some optional embodiments, a blood pressure detection module 3 is also included. The blood pressure detection module 3 is disposed within the housing 1 and is electrically connected to a drive circuit disposed inside the housing 1. When it is necessary to detect a patient's blood pressure, it can be measured through the blood pressure detection module 3 to obtain the patient's blood pressure data. By including the blood pressure detection module 3, the functionality of the electrocardiogram blood pressure monitor is expanded, meeting the needs for detecting various health data of patients.

[0046] In some optional embodiments, the blood pressure detection module 3 includes: an air pump disposed inside the housing 1, and an air tube connector 31 disposed on the housing 1. The air pump and the air tube connector 31 are connected by a pipeline, and the air pump is electrically connected to a drive circuit. A cuff is externally connected to the air tube connector 31, allowing the air pump to inflate and deflate the air bladder in the cuff, thereby compressing the patient's arm. The patient's blood pressure data is detected by a sensor on the cuff and electrically connected to the drive circuit of the electrocardiogram blood pressure monitor via a connecting wire. The patient's blood pressure is then displayed in real time on the display screen 11 of the electrocardiogram blood pressure monitor, and the patient's electrocardiogram and blood pressure data can be stored for later retrieval.

[0047] In some optional embodiments, a button module 12 is provided on the housing 1, and the button module 12 is electrically connected to a drive circuit disposed inside the housing 1. The button module 12 can be used to control the working status of the ECG and blood pressure monitor, including ECG and blood pressure detection. Simultaneously, in conjunction with the display screen 11 of the ECG and blood pressure monitor, it allows retrieval of various information obtained during different periods of patient testing, facilitating access for medical staff or patients to review changes in the patient's historical health data.

[0048] In the embodiments provided in this application, by dividing the contact point 2 into a measuring electrode 21 and a driving electrode 22, with each measuring electrode 21 equipped with a driving electrode 22, a localized and efficient common-mode interference suppression loop is formed. This structure helps to provide a more direct and stable reference for each measuring channel, thereby improving the overall common-mode rejection capability and anti-interference ability of the system. Furthermore, when used by a patient, the driving circuit 22 corrects the detected ECG information to obtain accurate ECG information from the patient, outputting a corresponding ECG, which facilitates medical personnel in providing a basis for diagnosis and treatment regarding whether the patient's heart rhythm is abnormal.
