Description

Technical Field

[0001] The present invention relates to the field of medical devices, in particular to a handheld electrocardiogram and heart sound synchronization sensor device. Background Art

[0002] An electrocardiogram primarily collects and displays electrophysiological signals from the patient's heart, while a phonocardiogram captures and displays mechanical motion signals from the heart and its pumping function, which are crucial parameters of cardiac function. Therefore, the simultaneous acquisition and analysis of both electrocardiograms and phonocardiograms provides a more comprehensive and multi-dimensional picture of cardiac function, while offering the ease of rapid clinical ECG screening and general investigation. This is similar to being able to simultaneously inspect a house's electrical circuits, doors, windows, walls, and other abnormalities, and is also useful for detecting waterway anomalies.

[0003] Synchronous detection of phonocardiogram and electrocardiogram helps to determine the period and nature of the patient's heart sounds or murmurs, thereby making a more comprehensive diagnosis and identification. It can be used for early screening of clinical diseases such as coronary heart disease, heart failure, and heart valves. Its clinical value is far greater than that of current non-invasive heart screening and examination equipment. However, it also requires going to the hospital for testing, and the testing equipment has problems such as long operation time, high difficulty, and high examination costs. It is not suitable for rapid screening and diagnostic surveys of heart diseases. For this reason, we propose a handheld electrocardiogram and heart sound synchronization sensor device to solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a handheld electrocardiogram and heart sound synchronization sensor device.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A handheld electrocardiogram and heart sound synchronization sensor device comprises an outer shell, on which collection probes are provided, one of which is a heart sound collection probe, and the other collection probes are an electrocardiogram collection probe and a ground line electrocardiogram probe.

[0007] A further technical solution is that there is one heart sound acquisition probe.

[0008] A further technical solution is that a suction cup-shaped flexible disinfection tray is provided on the outside of each of the ECG acquisition probes.

[0009] A further technical solution is that the heart sound collection probe is arranged on the resonance membrane, and the resonance membrane is located in the outer shell.

[0010] A further technical solution is that a signal processing circuit and a power supply electrically connected to the acquisition probe are provided in the outer shell.

[0011] A further technical solution is that an energy focusing head is provided on the resonance film, and the ground wire ECG probe overlaps with the energy focusing head.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention concentrates the ECG and heart sound acquisition probes on an outer shell. The user only needs to place the acquisition probe in the area to be tested on the body to collect physiological signals such as the ECG, heart sounds or lung sounds of the human body. The ECG, heart sounds or lung sound signals collected by the probe can be conveniently transmitted to the hospital or the patient's smart device for timely viewing after being processed by the signal processing circuit, which is convenient for users to use.

[0029] Example 1:

[0030] Please refer to Figure 1-4 shows an embodiment of a handheld ECG and heart sound synchronization sensor device, comprising an outer shell 1, on which are provided acquisition probes 2, one of which is a heart sound acquisition probe 21, the other three are ECG acquisition probes 22, and another is a ground wire ECG probe 23.

[0031] The heart sound acquisition probe 21 is provided with a resonant film component 15 and a signal acquisition microphone 13 in the outer shell 1, and an electrocardiogram acquisition probe is provided on the resonant film component 15. That is, during detection, the heart sound acquisition probe 21 is placed near the tricuspid valve auscultation area. At this time, the vibration of the resonant film component 15 is collected and amplified by the signal acquisition microphone 13 and then transmitted to the signal processing circuit, thereby achieving the purpose of collecting the heart sound signal in the area. At the same time, since the probe on it is in direct contact with the human body, it can monitor the electrocardiogram signal in the area. The monitored electrocardiogram signal is transmitted to the signal processing circuit through the wire, thereby achieving the purpose of homologous synchronous detection.

[0032] The three ECG acquisition probes 22 form a standard Ehrlich triangle, that is, the layout of the three ECG acquisition probes 22 conforms to the Ehrlich triangle law, and can perform ECG examinations on the human body. The ground ECG probe 23 is the zero potential point. The three ECG acquisition probes 22 and one ground ECG probe 23 are all electrically connected to the circuit board inside the outer shell 1, and they pass through the outer shell 1. When in use, they are in direct contact with the human skin and act as electrodes.

[0033] Each of the three ECG acquisition probes 22 is provided with a suction cup-shaped flexible disinfection disc, that is, the ECG acquisition probe 22 is connected to the hole reserved on the circuit board through the threaded end of the metal screw passing through the shell body, and at the same time, the non-threaded end of the screw presses the flexible disinfection disc onto the outer shell 1. During detection, the flexible disinfection disc opens under pressure, and the screw contacts the human skin. It is designed to preserve the gel. The gel is not only conductive, making the signal acquisition probe more closely contacted with the human body, but also can disinfect the signal acquisition probe.

[0034] The signal processing circuit includes an ECG signal probe processing circuit, a heart sound signal processing circuit, an AB converter, a power supply, a wired, wireless, and a wired and wireless hybrid module. The ECG signal probe processing circuit includes a five-channel ECG signal probe and an ECG signal circuit. The five-channel ECG signal probe is connected to the ECG processing circuit. The heart sound signal acquisition circuit is electrically connected to the signal acquisition microphone 13 and the heart sound signal processing circuit. The ECG signal processing circuit and the heart sound signal processing circuit both include voltage stabilization, filtering, signal amplification, and characteristic wave extraction. The device has a built-in power supply, which is replaceable.

[0035] When the device is in use, an operator can hold the outer shell 1 and attach the electrode end thereof to the part of the human body to be examined, or can tie the outer shell 1 to the part of the human body to be examined with a strap.

[0036] The outer shell 1 of the device adopts a split structure of an upper shell 12 and a lower shell 11. The upper shell 12 and the lower shell 11 are snap-connected, and its circuit control board 18 is snap-connected to the inside of the outer shell 1. In order to protect the internal circuit control board 18, the connection between the upper shell 12 and the lower shell 11 is sealed with a sealing ring.

[0037] The device is also provided with a signal acquisition probe connection port, a power supply port, and a signal output port electrically connected to the circuit control board 18 .

[0038] The circuit control board 18 is provided with a hexagonal nut connected to the ECG acquisition probe 22 and the ground ECG probe 23. Each flexible disinfection tray is provided with a screw adapted to the hexagonal nut, which connects each disinfection tray to the ECG acquisition probe 22 and the ground ECG probe 23.

[0039] A through hole is also provided at the bottom of the lower shell 11. A circular ring 16 concentric with the through hole is provided inside the lower shell 11, and the inner diameter of the circular ring 16 is larger than the inner diameter of the through hole. At this time, the resonant film assembly 15 can be placed in the circular ring 16, and the signal collection microphone 13 is connected to the circuit control board 18. At the same time, a clamping ring 14 is placed on the resonant film assembly 15. When the circuit control board 18 is connected to the lower shell 11, the top of the clamping ring 14 is in contact with the circuit control board 18. At the same time, the signal collection microphone 13 is located in the clamping ring 14 to collect the vibration sound from the resonant film assembly 15.

[0040] The resonant film assembly 15 includes a focusing head and a resonant film, with the focusing head disposed on the resonant film. The focusing head can be made of any material that can transmit sound, such as wood, plastic, metal, alloy, or other sound-transmitting materials. In a preferred embodiment, the focusing head is metal, such as iron, aluminum, steel, or an alloy. The focusing head should be thicker than the film, and its density per unit volume should be greater than that of the film. For example, if the film is an alloy sheet, the focusing head can be an alloy head. When detecting sound, the focusing head is in contact with the skin, while the film is kept away from the skin as much as possible. For example, when detecting heart sounds, the focusing head is in contact with the skin near the heart. The heart sounds are transmitted through the skin near the heart to the focusing head, which then transmits the sound to the film. We surprisingly discovered that using a film with a focusing head can amplify sound, particularly low-frequency sounds, enabling more comprehensive sound monitoring. Here, what is meant by trying not to let the film contact the skin can be that a small part of the film contacts the skin, at least the film where the energy focusing head is set does not contact the skin, and other places can contact the skin. Or, preferably, the film does not contact the skin at all, and only the energy focusing head contacts the skin.

[0041] When in use, the heart sound acquisition probe 21 of the device is preferably placed near the tricuspid valve auscultation area, that is, replacing the V2 lead position of the traditional electrocardiogram detection. Therefore, this application uses this position as the fixed position point of the heart sound acquisition probe 21 and describes it based on the heart sound and electrocardiogram signal acquisition. Of course, if other physiological sounds need to be detected, the device can also be attached to other physiological sound collection positions of the human body.

[0042] Example 2:

[0043] Please refer to Figure 5 The embodiment shown is different from the above-mentioned embodiment 1 in that: a plurality of ECG acquisition probes 22 are provided on the outer shell 1 , and the ECG acquisition probes 22 surround the heart sound acquisition probe 21 .

[0044] By providing a plurality of ECG acquisition probes 22 , a multi-lead ECG and heart sound synchronous acquisition device is formed.

[0045] Example 3:

[0046] Please refer to Figure 6 The embodiment shown is different from the above-mentioned embodiment 1 and embodiment 2 in that: an ECG acquisition probe 22 is provided on the outer shell 1, and the ECG acquisition probe 22 does not overlap with the heart sound acquisition probe 21.

[0047] By providing one ECG acquisition probe 22 , a single-lead ECG and heart sound synchronous acquisition device is formed.

[0048] Example 4:

[0049] The present embodiment differs from the above-mentioned embodiments 1, 2 and 3 in that the ground wire ECG probe 23 overlaps with the energy focusing head, that is, the ground wire ECG probe 23 is no longer separately provided on the outer shell 1, but the ground wire is connected to the energy focusing head.

[0050] Example 5:

[0051] Please refer to Figure 7 The embodiment shown is different from the above embodiment in that when the ECG acquisition probe 22 is connected to the circuit board, the end thereof retained outside the outer shell 1 is provided with a metal buckle connected to the circuit board. When the device is in use, a button electrode sheet that is compatible with it is fastened on the metal buckle. At this time, the button electrode sheet is in contact with the human body. After use, the button electrode sheet can be removed to meet hygiene requirements.

[0052] Please refer to Figure 8, each button electrode is fixed on a soft sheet. The soft sheet can be made of medical non-woven fabric, and the side of the medical non-woven fabric that contacts the human body is coated with adhesive except for the electrode sheet. The other end of the button electrode penetrates the soft sheet. At the same time, a hole is opened on the soft sheet for the heart sound collection probe 21 to pass through.

[0053] During use, each button electrode is aligned with the hidden button position on the outer shell 1 and then fastened together. The other end of each button electrode is in direct contact with the human body, and the heart sound collection probe 21 is also in contact with the human skin to achieve the purpose of monitoring. This method can avoid direct contact between the outer shell 1 and the human body to be tested, meeting the hygiene requirements. Since the button electrode and the soft thin sheet are relatively cheap, the soft thin sheet and the button electrode on it can be used as consumables for one-time use, fully meeting the hygiene requirements, and the heart sound collection probe 21 can be disinfected to meet the hygiene requirements.

[0054] As another implementation of this embodiment: it is also possible not to use soft thin sheets, but only to buckle button electrodes at the hidden buckle positions on the outer shell 1. When in use, the other end of each button electrode and the heart sound collection probe 21 are in contact with the human skin, and the bottom surface of the outer shell 1 is also in contact with the skin of the test person. After use, each button electrode is removed, and then the bottom surface of the outer shell 1 is disinfected as a whole. At this time, soft thin sheets can be saved, but the installation and removal speed and hygiene requirements of the button electrode and the outer shell 1 are not as good as the above-mentioned use of soft thin sheets.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
