[0028] Research has found that during dental treatment, patients need to lie in a dental chair. While existing dental chairs can adjust posture to improve comfort or provide auxiliary lighting for easier operation, they can pose safety risks, such as abnormal heart rate, for patients with cardiovascular disease during dental treatment, and current dental chairs cannot provide real-time alerts.
[0029] Based on the above research, this disclosure provides a non-intrusive ECG monitoring smart dental chair and its working method, which can collect the user's biological signals in real time, and the control module identifies and compares the biological signals to realize real-time monitoring of the user's status. The wireless communication unit and display unit quickly provide prompts, which facilitates more scientific and reasonable operation of the user and avoids safety risks caused by changes in status.
[0030] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0032] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0033] like Figures 1 to 5As shown, at least one embodiment provides a non-intrusive ECG monitoring smart dental chair, comprising: a seat body, two tannin monitoring units, a control unit, a wireless communication unit, and a display unit; wherein the two tannin monitoring units are respectively located on the armrests on both sides of the seat body, and the display unit is connected to the seat body; each of the tannin monitoring units, the wireless communication unit, the display unit, and the control unit is electrically connected to the control unit; the control unit is configured to acquire biological signals through the tannin monitoring units; the control unit is further configured to extract feature points from the biological signals to obtain corresponding judgment parameters, compare them with standard parameters, and then output corresponding recognition results; the control unit is further configured to send the recognition results to a mobile terminal through the wireless communication unit; and the control unit is further configured to display the recognition results through the display unit.
[0034] In at least one embodiment, by installing a tannin monitoring unit on the seat body, the user's biosignals can be collected in real time, and the control module can identify and compare the biosignals to realize real-time monitoring of the user's status. The wireless communication unit and display unit can quickly provide prompts, making it easier to take more scientific and reasonable actions to implement on the user and avoid safety risks caused by changes in status.
[0035] In at least one embodiment, please refer to Figure 3 The tannin-induced mental illness monitoring unit includes: a tannin-induced mental illness electrocardiogram electrode; the tannin-induced mental illness electrocardiogram electrode is located on the armrest of the seat body, and the tannin-induced mental illness electrocardiogram electrode is electrically connected to the control unit; the control unit is configured to acquire biological signals, i.e., electrocardiogram signals, through the tannin-induced mental illness electrocardiogram electrode.
[0036] Specifically, when using the device, users can lie on the seat and touch the Tanzhi ECG electrode to achieve real-time monitoring, display, and transmission of ECG signals, improving the user's treatment experience. At the same time, it enables physiological identification and safety hazard warning for cardiovascular patients, reducing operational safety risks.
[0037] Specifically, traditional hydrogel electrodes are prone to water loss when collecting ECG signals, cannot work for a long time, and have poor biocompatibility, while the Tanzhi ECG electrode achieves non-invasive detection of ECG signals.
[0038] Specifically, the Tanzhi ECG electrode can resist sweat interference and improve the accuracy of ECG signal detection.
[0039] In at least one embodiment, please refer to Figure 4The control unit is further configured to extract feature points from the biosignal to obtain corresponding judgment parameters, compare them with standard parameters, and then output corresponding recognition results. Specifically, the control unit performs noise reduction on the electrocardiogram (ECG) signal through filtering; the control unit performs feature point detection on the denoised ECG signal to identify the R wave, QRS complex, P wave, and T wave of the ECG signal; the control unit segments the ECG signal into different cardiac cycles based on adjacent R waves to obtain the corresponding average heart rate and heart rate variability; and the control unit outputs the corresponding recognition results based on the average heart rate and heart rate variability.
[0040] Specifically, the acquired electrocardiogram (ECG) signals are filtered to remove noise information such as power frequency interference, baseline drift, and electromyographic interference. Then, feature point detection is performed on the denoised ECG signals to accurately identify the R wave, QRS complex, P wave, and T wave. The ECG signal is segmented into different cardiac cycles based on adjacent R waves to obtain the average heart rate (HR). A warning signal is issued when tachycardia (HR>120) or bradycardia (HR<60) occurs. Furthermore, heart rate variability (HRV) is calculated to obtain the relationship between adjacent heartbeat interval time series. Using time-frequency domain analysis methods, key time-frequency domain indicators such as SDNN, SDANN, NN50, TP, LFP, and HFP are extracted. Statistical analysis methods are used to detect differences in ECG indicators between the experimental and control groups, selecting the most specific ECG indicators to construct an indicator set. Finally, a screening model is constructed by comparing classifiers such as Bayesian networks, logistic regression analysis, support vector machines, multilayer perceptrons, nearest neighbor classification, and random forests to achieve accurate identification of cardiovascular diseases.
[0041] In at least one embodiment, please refer to Figure 5 The control unit constructs a multi-level retrieval database according to the set thresholds of average heart rate and heart rate variability corresponding to different recognition results; after the control unit obtains the average heart rate and heart rate variability, it searches the multi-level retrieval database to obtain the corresponding recognition results.
[0042] Specifically, by constructing a multi-level retrieval database, once the average heart rate and heart rate variability are collected, the corresponding recognition results can be directly retrieved from the multi-level retrieval database, thus meeting the need for fast and real-time prompts.
[0043] In at least one embodiment, the tanning electrocardiogram electrode includes: a flexible substrate and a conductive material; the conductive material is compositely connected to the flexible substrate, and the conductive material is electrically connected to the control unit; when the flexible substrate and the conductive material are touched, an electrocardiogram signal is acquired and sent to the control unit.
[0044] In at least one embodiment, the flexible substrate is leather or fabric.
[0045] Specifically, leather is selected as the base material for the Tanzhi ECG electrode, which has good biocompatibility. Based on the multi-level network structure of leather, it can be combined with functional sensing materials to produce a Tanzhi ECG electrode with excellent electrical properties while maintaining the tactile feel of leather.
[0046] In at least one embodiment, the conductive material is one or more of carbon-based materials, metal nanomaterials, non-metal nanomaterials, conductive polymers, and conductive inks.
[0047] Specifically, conductive polymers are selected as the conductive materials, possessing excellent conductivity and good film-forming properties on substrates. By utilizing the multi-level structure of leather and its active functional groups, conductive materials based on conductive polymers are developed. To meet the requirements for acquiring electrocardiogram (ECG) signals (normal amplitude typically 0.05–5 mV, frequency range generally 0.05–100 Hz), a tanning-based ECG electrode is fabricated.
[0048] In at least one embodiment, please refer to Figure 3 The control unit includes a microprocessor and an amplification filter. The microprocessor amplifies and filters the biological signal through the amplification filter, extracts each feature point from the biological signal to obtain the corresponding judgment parameters, compares them with standard parameters, and then outputs the corresponding recognition result.
[0049] Specifically, the amplification filter can be a Butterworth filter or a discrete wavelet filter.
[0050] In at least one embodiment, please refer to Figure 3 The wireless communication unit includes a Bluetooth chip; the Bluetooth chip is electrically connected to a microprocessor; the microprocessor sends the recognition result to a mobile terminal via the Bluetooth chip; the display module includes a display; the display is electrically connected to the microprocessor; the microprocessor displays the recognition result via the display.
[0051] Specifically, a Bluetooth chip with low power transmission and a display are used to realize wired and wireless data transmission. The microprocessor can realize real-time monitoring and storage of electrocardiogram (ECG) signals, as well as preliminary analysis and diagnostic assessment of ECG signals.
[0052] Based on the same technical concept, at least one embodiment also provides a working method for the smart dental chair with non-contact ECG monitoring as described above, which includes: a control unit acquiring biological signals through a tannin monitoring unit; the control unit extracting each feature point from the biological signals to obtain corresponding judgment parameters, comparing them with standard parameters, and then outputting the corresponding recognition result; the control unit sending the recognition result to a mobile terminal through a wireless communication unit; and the control unit displaying the recognition result through a display unit.
[0053] In summary, this invention, by installing a tannin monitoring unit on the seat body, can collect the user's biosignals in real time. The control module identifies and compares these biosignals to monitor the user's status in real time. The wireless communication unit and display unit can quickly provide prompts, facilitating more scientific and reasonable operations to be implemented on the user and avoiding safety risks caused by changes in status.
[0054] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
[0055] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.
[0056] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0057] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0058] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
