Description

Technical Field

[0001] This invention relates to the field of electrocardiography (ECG) technology, and particularly to an ECG lead electrode adsorption device. Background Technology

[0002] Electrocardiographs (ECGs) are widely used in hospitals at all levels and various health check-up institutions, providing doctors with crucial information for diagnosis and treatment. All models of ECGs used clinically require the patient to expose their chest, and medical staff then attach the ECG leads to the patient's chest and limbs. Chest leads are typically patch or bulb-type structures with metal electrodes. These chest leads are connected to the ECG machine via lead wires. During use, the chest lead electrodes are fixed in the corresponding positions on the chest to collect ECG signals, which are then transmitted to the ECG machine via the lead wires.

[0003] Because the patch structure uses conductive adhesive and medical adhesive to fix the electrodes to the body, it is a disposable consumable and cannot be reused, increasing the cost for patients. Furthermore, when removing the electrodes, the adhesive can damage the patient's body hair and even skin, and the adhesive residue left on the skin is difficult to clean. Long-term use can cause skin redness and itching. The fact that people with adhesive allergies cannot use the adhesive structure also limits its application. The suction bulb structure uses negative pressure adsorption to fix the electrodes to the body. Different patients have different skin conditions, requiring different adsorption forces. Moreover, it requires medical staff to manually squeeze the suction bulb, which is cumbersome and affects their work efficiency.

[0004] Therefore, there is a need for an electrocardiogram lead electrode adsorption device that can improve operational efficiency while ensuring adsorption force. Summary of the Invention

[0005] This invention provides an electrocardiogram lead electrode adsorption device that can improve operational efficiency while ensuring adsorption force.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] An electrocardiogram lead electrode adsorption device includes a suction cup, a terminal block fixed to the side wall of the suction cup, an air nozzle on the top of the suction cup, a one-way valve fixed to the air nozzle, and a suction mechanism; the suction mechanism includes a control module, a suction nozzle, and a vacuum pump connected to the suction nozzle.

[0008] The control module includes an input unit, a storage unit, and a processing unit. The input unit is used to receive patient information and suction cup position information. The storage unit stores several suction data in advance. The processing unit is used to match the current suction data according to the patient information, suction cup position information, and suction data in the storage unit. The processing unit is also used to control the vacuum pump to work according to the current suction data.

[0009] The basic principles and beneficial effects of the scheme are as follows:

[0010] When using this device, medical staff first input the patient's information and the location information of the suction cups. Then, they place the suction cups in the designated positions according to the installation sequence, connect the suction nozzle of the suction mechanism to the air nozzle of the suction cup, and start the vacuum pump until the suction pressure threshold is reached, at which point the vacuum pump stops working. This creates negative pressure inside the suction cup, which is then placed on the patient's skin. The lead wires are then connected to the terminals on the side wall of the suction cup. The remaining suction cups are then installed. Finally, the electrocardiogram (ECG) test begins.

[0011] This solution uses negative pressure instead of adhesive, reducing the likelihood of skin allergies. Automatic air extraction via a vacuum pump makes operation more convenient compared to manual squeezing of the suction bulb by medical staff. The suction cups, without a suction bulb, are smaller and less prone to accidental detachment. Pre-stored air extraction data allows for different settings to be configured for different skin conditions at different suction cup locations, creating varying negative pressures. This targeted approach ensures effective adhesion at various locations compared to using the same negative pressure.

[0012] Furthermore, the control module also includes a pressure detection unit;

[0013] The air pressure detection unit is used to detect the current suction pressure when the vacuum pump is working;

[0014] The processing unit is also used to determine whether the current suction pressure has reached the suction pressure threshold in the current pumping data. If the suction pressure threshold is reached, the vacuum pump is automatically controlled to stop working.

[0015] Furthermore, the patient information includes the patient's gender, age, and skin type.

[0016] Furthermore, the position information of the suction cups includes the installation order of all suction cup positions, or the position information of the current suction cup;

[0017] The processing unit is also used to determine the current suction cup position information based on the number of times the vacuum pump has been operated when the received suction cup position information is the installation sequence of all suction cup positions.

[0018] The installation order of all suction cups can be entered in advance, or the installation order of all suction cups can be set to the default value. When using it, medical staff do not need to enter the position for each suction cup. The processing unit can automatically determine the current suction cup position based on the number of times the vacuum pump has worked. For example, if the vacuum pump has worked 5 times, then it is time to evacuate the sixth suction cup, which is more convenient to use.

[0019] Furthermore, the control module also includes a contact detection unit, which generates a start signal after detecting contact between the suction nozzle and the air nozzle;

[0020] The processing module is also used to control the vacuum pump to operate after receiving the start signal.

[0021] After medical staff connect the suction nozzle to the air nozzle, the vacuum pump will start automatically, making operation more convenient.

[0022] Furthermore, the input unit is also used to receive a manual control signal after the automatic control vacuum pump stops working, and the processing unit is also used to control the vacuum pump to work according to the manual control signal.

[0023] The processing unit is also used to record the suction pressure when the manually controlled vacuum pump stops working, mark it as the corrected suction pressure, and store it.

[0024] Medical staff can manually adjust the vacuum pump after it starts working automatically.

[0025] Furthermore, the control module also includes a server and a communication unit. The communication unit is used to send the corrected inhalation pressure to the server. The server is used to modify the pumping data according to the corrected inhalation pressure and update the pumping data in the storage unit based on the modified pumping data.

[0026] Based on the collected and adjusted data, namely the correction of the suction pressure, the suction data is modified to make the suction data more consistent with actual use. This means that the negative pressure formed inside the suction cup achieves a better balance between the strength of the adhesion and the prevention of skin damage.

[0027] Furthermore, it also includes an electrocardiograph (ECG). The communication unit is also used to obtain the position information of the access suction cup from the ECG, and the processing unit is also used to determine whether the position information of the access suction cup is consistent with the determined current suction cup position information. If they are inconsistent, it determines whether a manual control signal is received. If received, the corresponding corrected inspiratory pressure is deleted. If not received, it determines whether the suction data corresponding to the position information of the access suction cup is consistent with the suction data corresponding to the determined current suction cup position. If they are inconsistent, a reminder message is generated.

[0028] When medical staff do not install the suction cups according to the input installation sequence, the suction cup position calculated by the processing unit may differ from the actual suction cup position, and the inspiratory pressure threshold used may also be inconsistent, potentially causing the suction cups to detach. In this preferred solution, the position information of the connected suction cups is obtained from the electrocardiograph to determine if a positional inconsistency has occurred. If so, a reminder message is generated to draw the attention of medical staff if no manual adjustment is made. If manual adjustment has been made by medical staff, the corresponding corrected inspiratory pressure is deleted to avoid collecting erroneous adjustment data.

[0029] Furthermore, the communication unit is also used to obtain the position information of the suction cup corresponding to the detection interruption from the electrocardiograph, and the processing unit is also used to mark the corresponding suction data as abnormal suction data and send the abnormal suction data to the server through the communication unit. Attached Figure Description

[0030] Figure 1 This is a logic block diagram of the electrocardiogram lead electrode adsorption device in Example 1. Detailed Implementation

[0031] The following detailed description illustrates the specific implementation methods:

[0032] Example 1

[0033] The electrocardiogram lead electrode adsorption device of this embodiment includes a suction cup and a suction mechanism.

[0034] A terminal block is fixed to the side wall of the suction cup, and an air nozzle is provided on the top of the suction cup, with a one-way valve fixed to the air nozzle. In this embodiment, the one-way valve is an umbrella-shaped one-way valve.

[0035] The suction mechanism includes a control module, a suction nozzle, a vacuum pump connected to the suction nozzle, and a power supply; the power supply provides power to the control module.

[0036] like Figure 1 As shown, the control module includes an input unit, a storage unit, a processing unit, an air pressure detection unit, a drive unit, and a contact detection unit;

[0037] The input unit receives patient information and suction cup location information; the patient information includes the patient's name, gender, age, and skin type. In this embodiment, skin type includes dry skin, normal skin, and oily skin, etc.; the patient information is input by scanning the QR code on the patient's wristband to obtain the name, and then obtaining the pre-stored gender, age, and skin type based on the name. In other embodiments, the patient information can also be manually entered by medical staff on-site.

[0038] The suction cup position information includes the installation order of all suction cups, or the current suction cup position. The installation order of all suction cups is, for example: V1, V2, V3, V4, V5, V6. Specifically, V1 is located at the 4th intercostal space along the right sternal border; V2 is located at the 4th intercostal space along the left sternal border; V4 is located at the 5th intercostal space along the left midclavicular line; V3 is located at the midpoint of the line connecting V2 and V4; V5 is located at the same level as V4 along the left anterior axillary line; and V6 is located at the same level as V4 along the midaxillary line. The current suction cup position is, for example: V5.

[0039] The storage unit contains pre-stored suction data. In this embodiment, different genders are pre-defined, then different age groups are defined within each gender, and finally, suction data is set for the location of each suction cup for different skin types within each age group. The suction data for different suction cup locations can be different, or the suction data for some suction cup locations can be the same. The suction data includes suction pressure thresholds. The pre-stored suction pressure thresholds can be obtained through testing, ensuring that the suction cups do not detach or damage the patient's skin during testing.

[0040] The control module also includes a contact detection unit, which generates a start signal after detecting contact between the suction nozzle and the air nozzle. In this embodiment, the contact detection unit uses a micro switch. The inner diameter of the suction nozzle is larger than the outer diameter of the air nozzle. The micro switch is installed inside the suction nozzle. After the suction nozzle contacts the air nozzle, the air nozzle presses the micro switch, which is then turned on, generating an electrical signal, i.e., the start signal.

[0041] The processing unit determines the current suction cup position based on the number of times the vacuum pump has operated when the received suction cup position information indicates the installation sequence of all suction cup positions. In this embodiment, the time from when the suction nozzle contacts the air nozzle, when the vacuum pump starts, to when the vacuum pump automatically stops is counted as one vacuum pump operation.

[0042] The processing unit matches the current suction data with patient information, suction cup position information, and suction data stored in the unit. Upon receiving a start signal, the processing module also controls the vacuum pump to operate based on the current suction data; specifically, it drives the vacuum pump via a drive unit. The pressure detection unit detects the current suction pressure while the vacuum pump is operating. The processing unit also determines whether the current suction pressure reaches the suction pressure threshold in the current suction data; if it does, it automatically stops the vacuum pump.

[0043] Taking the input suction cup position information as the installation sequence of all suction cups as an example, when using this adsorption device, first input the patient information and suction cup position information, then place the first suction cup in the designated position according to the installation sequence, connect the suction nozzle of the suction mechanism to the air nozzle of the suction cup, the vacuum pump works until the inhalation pressure threshold is reached, and then the vacuum pump stops working; connect the lead wire to the terminal on the side wall of the suction cup; then complete the installation of the remaining suction cups according to the installation sequence; finally, start the electrocardiogram test.

[0044] Example 2

[0045] The difference between this embodiment and Embodiment 1 is that this embodiment also includes a server and an electrocardiograph. The control module also includes a communication unit.

[0046] The input unit is also used to receive a manual control signal after the automatic control vacuum pump stops working, and the processing unit is also used to control the vacuum pump to work according to the manual control signal. In this embodiment, the manual control signal is input through a button switch. Pressing the button controls the vacuum pump to work, and releasing the button controls the vacuum pump to stop working.

[0047] The processing unit is also used to record the suction pressure when the manually controlled vacuum pump stops working, mark it as the corrected suction pressure, and store it.

[0048] The communication unit is used to send the corrected inspiratory pressure to the server. In this embodiment, the communication unit is also used to send the device number of the suction mechanism corresponding to the corrected inspiratory pressure, the current position information of the suction cup, and the patient information.

[0049] The server modifies the suction data based on the corrected inspiratory pressure and updates the suction data in the storage unit based on the modified suction data. Specifically, the server receives corrected inspiratory pressures from different suction mechanisms, different patients, and different suction cup positions. First, it performs preliminary screening of the corrected inspiratory pressures, eliminating those with a change in magnitude exceeding a set value. Then, after the number of corrected inspiratory pressures for the same type of patient and the same suction cup position reaches a set number, the average of the corrected inspiratory pressures is calculated as a new inspiratory pressure threshold. The change in magnitude is calculated by subtracting the corresponding inspiratory pressure threshold from the corrected inspiratory pressure and then dividing by the corresponding inspiratory pressure threshold. "Same type of patient" refers to patients of the same gender, age group, and skin type. In this embodiment, the set value is 30%.

[0050] The communication unit is also used to obtain the position information of the accessed suction cup from the electrocardiograph. In this embodiment, after vacuuming is completed, the suction nozzle is separated from the air nozzle, and then the lead wires of the electrocardiograph are connected to the terminals on the side wall of the suction cup. Since different suction cups correspond to different lead wires, after connection, the electrocardiograph can obtain an electrical signal, and the position information of the currently accessed suction cup can be obtained based on the electrical signal.

[0051] The processing unit is also used to determine whether the position information of the access suction cup is consistent with the determined current suction cup position information; if they are inconsistent, it determines whether a manual control signal has been received; if received, the corresponding corrected suction pressure is deleted; if not received, it determines whether the suction data corresponding to the position information of the access suction cup is consistent with the suction data corresponding to the determined current suction cup position; if they are inconsistent, a reminder message is generated. In other embodiments, a buzzer or similar device can be set to provide an audible alarm reminder.

[0052] Example 3

[0053] The difference between this embodiment and embodiment two is that in this embodiment, the communication unit is also used to obtain the position information of the suction cup corresponding to the detection interruption from the electrocardiograph, and the processing unit is also used to mark the corresponding suction data as abnormal suction data and send the abnormal suction data to the server through the communication unit.

[0054] The machine's operating data is used to check if any point is loose, and then feedback is given on whether the suction pressure is appropriate. By sending abnormal suction data to the server, after a certain number of times, the suction data at that location can be adjusted to reduce the probability of loosening.

[0055] Example 4

[0056] The difference between this embodiment and Embodiment 2 is that, in this embodiment, the control module further includes an electromagnet, which is electrically connected to the drive unit. The electromagnet is ring-shaped and circumferentially fixed around the suction nozzle. A ring-shaped iron plate is also fixed around the air nozzle; in this embodiment, the ring-shaped iron plate is wrapped with insulating plastic.

[0057] The input unit is also used to receive the identity information of medical staff, and the communication unit is also used to send the identity information of medical staff and the position information of the access suction cup to the server to determine whether the current position information of the suction cup is consistent.

[0058] The server is also used to record the usage habits of medical staff based on their identity information and judgment information, and to classify medical staff according to their usage habits. The classification includes sequential installation and non-sequential installation. In this embodiment, if the location information of the access suction cup is inconsistent with the current suction cup location information more than 3 times, it is classified as follows:

[0059] The communication unit is also used to obtain the position information of the suction cup corresponding to the detection interruption from the electrocardiograph and send the detection interruption information to the server.

[0060] The server is also used to determine whether there is a corresponding detection interruption information among the medical staff who installed the corresponding category out of order. If so, the medical staff is marked as a special user; the information of the special user is sent to the storage unit for storage through the communication unit.

[0061] The processing unit is also used to determine whether the current medical staff member is a special user based on the current medical staff member's identity information and the stored special user information. If so, after controlling the vacuum pump to stop working, the drive unit controls the electromagnet to be energized and starts timing. If the signal is interrupted within a preset time, the electromagnet is immediately de-energized and the status is marked as "detection passed". If the signal is not interrupted within a preset time, the electromagnet terminal is controlled and the status is marked as "detection failed". The preset time is 3-5 seconds. In this embodiment, the preset time is 3 seconds.

[0062] The communication unit is also used to send status information to the server; the server is also used to cancel the special user mark of the medical staff after 18 consecutive successful detections, and re-evaluate based on subsequent new data, i.e., reset. In this embodiment, 18 consecutive detections are based on 6 suction cups per group and 3 groups tested. In other embodiments, this can be adjusted according to actual conditions.

[0063] This embodiment, based on user habits, identifies medical personnel who do not install the suction cups in the correct order and experience detachment. Testing is then conducted during their use of the suction mechanism: After the vacuum pump stops working, the medical personnel need to remove the entire suction mechanism from the air nozzle. At this time, the electromagnet is energized, generating a certain attraction force on the annular iron plate. If the suction cup is not securely fixed, it will be pulled off along with the entire suction mechanism; if the suction cup is securely fixed, the suction mechanism separates from the air nozzle, and the electrical signal of the contact detection unit is interrupted. This detection allows for the early detection of loosely fixed suction cups, effectively preventing them from detaching during use. The electromagnet's magnetic force in this embodiment requires multiple experiments for calibration to control the magnetic force within a small range, avoiding excessive magnetic force that could pull off properly attracted suction cups.
