Description

Technical Field

[0001] The present invention relates to the technical field related to depression testing, and in particular to a depression identification testing device. Background Art

[0002] Depression is a serious mental health problem that can worsen if not identified and treated promptly. Depression testing can identify potential depressive symptoms early, allowing patients to receive timely intervention and support.

[0003] Traditional depression diagnosis relies on clinical interviews with doctors and self-assessments using questionnaires, but these methods can carry the risk of misdiagnosis. In recent years, artificial intelligence and machine learning technologies have been used to automatically identify depression, improving diagnostic accuracy and efficiency. Currently, heart rate variability (HRV) analysis is used to assist in assessing autonomic nervous system activity, providing reference data for potential biomarkers of depression. Heart rate analysis is performed by recording the patient's heart's electrical activity using an electrocardiograph (ECG). This instrument typically consists of electrodes, a signal acquisition module, a data processing system, and a display device. The ECG is connected to the patient via electrodes and captures the heart's electrical activity. After processing through an amplifier and filter, these signals are transmitted to the signal acquisition module. The captured ECG signals can be transmitted in real time to a host or mobile device and stored in internal or external memory for subsequent analysis and review.

[0004] The electrodes of the ECG lead wire should be attached to specific positions on the patient's body according to the instructions of the electrocardiograph or monitor. When connecting the ECG lead wire set on the existing electrocardiograph to the patient, shave the chest hair and wipe the skin dry before attaching the electrodes. The electrodes are attached to the patient's chest or other parts with tape to ensure close contact between the electrodes and the skin. Once the patient sweats on the skin again during the heart rate measurement process, the adhesion between the electrodes and the skin will be reduced, which may cause the electrodes to fall off or signal interference.

DETAILED DESCRIPTION

[0037] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0038] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0039] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0040] See also Figures 1 to 10In an embodiment of the present invention, a depression identification test device includes an operating table 1 and an electrocardiograph 2 placed on the operating table 1, wherein the electrocardiograph 2 is connected to an electrocardiogram lead wire capable of measuring the heart rate of a user;

[0041] The ECG lead wire comprises a hard tube 3 and a soft tube 4, wherein the hard tube 3 and the soft tube 4 are provided with a communicating annular cavity and a conductive wire;

[0042] It also includes a negative pressure box 12 fixedly mounted on the operating table 1 and connected to the annular cavity. The negative pressure box 12 is provided with a pushing mechanism capable of adsorbing the air in the annular cavity. The lead block 6 provided at the end of the hose 4 can be adsorbed and fixed to the user's skin.

[0043] An elastic triggering member is arranged in the negative pressure box 12, and the pushing mechanism abuts against the elastic triggering member. After vacuum adsorption in the lead block 6, the elastic potential energy stored in the elastic triggering member acts on the sensor 21 arranged in the negative pressure box 12, and the sensor 21 establishes communication with the electrocardiograph 2 and the pushing mechanism respectively.

[0044] Preferably, the end of the soft tube 4 away from the hard tube 3 is connected to multiple wire branches so that the soft tube 4 can be simultaneously attached to the patient's chest or other parts to measure the heart rate.

[0045] In this embodiment, the activity of the autonomic nervous system is assessed by measuring the patient's heart rate variability as a potential biomarker for depression. When measuring the patient's heart rate, the lead block 6 is attached to a specific position on the patient's body according to the instructions of the electrocardiograph 2. Multiple lead blocks 6 are pressed in succession to achieve initial fixation between the lead block 6 and the patient's skin. At this time, the contact between the lead block 6 and the skin is not complete, but it can effectively achieve a simple positioning of the lead block 6 at a specific position on the patient's body to prevent the lead block 6 from separating from the skin. By starting the pushing mechanism, the pressure in the negative pressure box 12 is reduced, thereby absorbing the air between the lead block 6 and the skin, forming a vacuum environment, effectively enhancing the fit and stability between the lead block 6 and the skin, thereby reducing signal interference and artifacts caused by poor fit. This design helps to improve the acquisition quality of electrocardiogram signals, reduce signal interference, and make measurement results more accurate.

[0046] At the same time, when the push mechanism performs the push operation, it squeezes the spring trigger, causing the elastic trigger to store elastic potential energy. The moment the air between the lead block 6 and the skin is completely expelled, the elastic force stored in the elastic trigger instantly bursts out and acts on the sensor 21, causing the sensor 21 to send a signal to the push mechanism and the electrocardiograph 2 at the same time, so that the push mechanism quickly stops pushing, and the electrocardiograph 2 starts measuring the user's heart rate, thereby achieving rapid capture and response to the ECG signal. This rapid response mechanism helps improve the accuracy of the electrocardiograph 2 in dynamic monitoring, especially in medical scenarios that require real-time monitoring.

[0047] In contrast, the lead block 6 currently available on the market is usually fixed to the patient's skin by adhesive bonding. This connection method is premised on skin cleanliness and preparation. Before using the lead block 6, the skin needs to be cleaned to remove grease, dirt, sweat, etc. to improve the conductivity of the skin. At the same time, in order to ensure good contact between the lead block 6 and the skin, it is necessary to ensure that the lead block 6 can fit tightly against the skin to ensure that the current can flow evenly to the human body through the contact surface with the skin. If the lead block 6 cannot completely and tightly contact the skin, the current may be concentrated at one or several points on the skin, causing a tingling sensation on the skin surface, or even skin burns in severe cases.

[0048] It should be noted that when the lead block 6 is fixed to the skin, if the skin sweats again during heart rate measurement after cleaning, it will have a certain impact on the fixation of the lead block 6 to the skin. Sweat will combine with the gel-like substance in the lead block 6, forming a layer of film that hinders conductivity, thereby reducing the adhesion between the lead block 6 and the skin. Negative pressure adsorption technology can alleviate this problem to a certain extent. Negative pressure adsorption allows the air in the lead block 6 to be discharged, forming negative pressure adsorption on the skin surface, thereby achieving close contact with the skin. This fixing method can reduce the risk of the lead block 6 falling off due to sweating, and at the same time, it can also prevent the influence of sweat on the contact between the lead block 6 and the skin to a certain extent. The contact area of ​​the negative pressure adsorption electrode is larger, which can better disperse the pressure on the skin surface, reduce the deformation of the skin caused by pressure, and thus reduce the interference of sweat on the measurement.

[0049] Preferably, the lead block 6 is provided with an electrode sheet 601 and a suction cup 602 , and the electrode sheet 601 and the suction cup 602 are communicated with the conductive wire and the annular cavity respectively.

[0050] Among them, the electrode sheet 601 establishes a bridge between the conductive wire and the patient's skin. The current generated by the electrical activity of the heart is transmitted to the body surface through body fluids (such as blood and tissue fluid) and captured by the electrode sheet 601 placed on the body surface. The captured electrical activity signal is transmitted to the electrocardiograph 2 through the conductive wire, and then amplified and filtered by the amplifier and filter provided in the electrocardiograph 2. It is collected and imported into the host in the electrocardiograph 2 for digital storage.

[0051] As a further solution of the present invention, please refer to Figure 9 and Figure 10 The pushing mechanism includes a screw rod 15 rotatably arranged on the negative pressure box 12, and a threaded sleeve 17 is threadedly connected to the screw rod 15. An extrusion plate 16 that is slidably connected to the inner wall of the negative pressure box 12 is fixedly installed on the end of the threaded sleeve 17 away from the screw rod 15.

[0052] The negative pressure box 12 is connected to the annular cavity in the hard tube 3 through a connecting pipe 14 .

[0053] A connecting seat 5 is provided on one end of the hose 4 away from the hard tube 3 , and a plurality of wire branches are connected to the connecting seat 5 , and the wire branches are respectively connected to lead blocks 6 .

[0054] Preferably, at least one set of limiting grooves 1201 is formed on the inner wall of the negative pressure box 12, and a limiting block 1601 that slides with the limiting grooves 1201 is provided on the extrusion plate 16. Under the restriction of the limiting grooves 1201 and the limiting block 1601, the sliding connection between the negative pressure box 12 and the extrusion plate 16 is realized, and a limiting effect is played on the movement of the threaded sleeve 17.

[0055] It should be noted that the screw 15 is driven to rotate by the motor 13 fixedly installed on the negative pressure box 12. When the motor 13 starts working, it drives the screw 15 to rotate synchronously, thereby driving the threaded sleeve 17 to move linearly along the axial direction of the screw 15, so that the gas volume in the lower end chamber of the negative pressure box 12 increases and the pressure decreases. Under the action of the connecting tube 14, the air in the lead block 6 is pumped to the hose 4 to the hard tube 3 and collected in the negative pressure box 12, so as to form a vacuum environment between the lead block 6 and the skin. After the air in the lead block 6 is exhausted, under the action of the elastic trigger part, the negative pressure adsorption work can be quickly stopped, avoiding the potential damage to the skin tissue caused by unnecessary continuous negative pressure, and at the same time improving the controllability and efficiency of the heart rate measurement process.

[0056] As a further solution of the present invention, please refer to Figure 10 A first push rod 1701 and a second push rod 1702 are fixedly provided on the threaded sleeve 17, and the first push rod 1701 and the second push rod 1702 can push the elastic triggering member respectively.

[0057] The elastic triggering member includes a support base 18 fixedly mounted on the negative pressure box 12, and a deflection rod 19 rotatably mounted on the end of the support base 18, which can abut against the first push rod 1701 and the second push rod 1702;

[0058] The second spring 20 is further included. One end of the second spring 20 is hinged to the support seat 18 , and the other end of the second spring 20 is hinged to the deflection rod 19 .

[0059] The support seat 18 is symmetrically provided with a first positioning block 1801 and a second positioning block 1802 for limiting the tilt of the deflection rod 19 .

[0060] In the initial state, the second spring 20 is in a stretched state. At this time, the second spring 20 generates a force on the deflection rod 19 to rotate toward the first positioning block 1801. Under the limit of the first positioning block 1801, the deflection rod 19 cannot rotate toward and beyond the first positioning block 1801. At the same time, the first push rod 1701 abuts against one end of the deflection rod 19. When the above-mentioned threaded sleeve 17 makes a linear motion along the axial direction of the screw rod 15, the first push rod 1701 squeezes the deflection rod 19 at this time, and the thrust of the first push rod 1701 on the deflection rod 19 is greater than the elastic force of the second spring 20, so that the deflection rod 19 can overcome the resistance of the second spring 20 and rotate in the direction away from the first positioning block 1801. When the air between the lead block 6 and the skin is exhausted, the first push rod 1701 pushes the deflection rod 19 to deflect to the same horizontal line as the support seat 18. At this time, the tensile potential energy of the second spring 20 is at its maximum value, and the force between the deflection rod 19 and the support seat 18 is balanced. When the first push rod 1701 continues to move until the deflection rod 19 and the support seat 18 are out of balance, under the elastic force of the second spring 20, the deflection rod 19 quickly deflects toward the direction of the second positioning block 1802 and can quickly trigger the sensor 21, so that the sensor 21 sends a signal to the motor 13 and the electrocardiograph 2, so that the negative pressure adsorption work can be quickly stopped while quickly capturing and responding to the electrocardiogram signal.

[0061] As a further solution of the present invention, please refer to Figure 4 and Figure 5 The operating table 1 is provided with a reeling mechanism capable of retracting and unfolding the hose 4 .

[0062] The winding mechanism includes a winding drum 7 rotatably mounted on the operating table 1 , a first limiting ring 8 is provided along the axial direction of the winding drum 7 , and the first limiting ring 8 is provided with a plurality of first latching teeth 801 equidistantly along the circumference;

[0063] It also includes an elastic locking member, which is arranged along the axial direction of the winding drum 7 and connected to the operating table 1. The elastic locking member can lock the rotation of the first limiting ring 8.

[0064] The elastic locking member includes a connecting tube 11 fixedly mounted on the operating table 1, a second limiting ring 9 is slidably mounted on the connecting tube 11, and the second limiting ring 9 is provided with a plurality of second latching teeth 901 along the circumference thereof, which can engage with the first latching teeth 801;

[0065] It also includes a first spring 10 , which is sleeved on the connecting tube 11 , with one end of the first spring 10 abutting against the end of the connecting tube 11 , and the other end abutting against the second limiting ring 9 .

[0066] Preferably, at least one group of strip blocks 902 is provided on the inner ring of the second limiting ring 9, and a strip groove 1101 is formed on the connecting tube 11, which slides with the strip block 902. Under the restriction of the strip block 902 and the strip groove 1101, the sliding connection between the second limiting ring 9 and the connecting tube 11 is realized. When the second latch 901 is subjected to the tilting force generated by the first latch 801, the second limiting ring 9 can make a linear motion along the axial direction of the connecting tube 11.

[0067] In order to prevent the ECG lead wires from getting tangled or knotted during daily use, the hose 4 is reeled in. By controlling the rotation of the reel-in 7, the hose 4 can be quickly reeled in. When the reel-in 7 rotates, the second limiting ring 9 and the first limiting ring 8 are engaged, so the reel-in 7 can be locked at any time.

[0068] In detail, when the winding drum 7 rotates, it drives the first limit ring 8 to rotate at the same time. During the rotation, the first limit ring 8 rotates relative to the second limit ring 9, so that the first latch 801 generates an inclined force on the second latch 901, thereby squeezing the second limit ring 9 to make a linear motion along the axial direction of the connecting tube 11. When the second limit ring 9 moves, it squeezes the second spring 20, so that the elastic compression potential energy of the second spring 20 increases. When the winding drum 7 stops rotating, the first limit ring 8 stops squeezing the second limit ring 9, and the second spring 20 releases its elastic potential energy, driving the second limit ring 9 to reset. At this time, the first latch 801 and the second latch 901 abut against each other, thereby preventing the winding drum 7 from rotating.

[0069] When the first tooth 801 rotates relative to the second tooth 901, the inclined surface of the first tooth 801 generates an inclined force on the inclined surface of the second tooth 901. In the initial state, the second spring 20 is in a compressed state. At this time, the isosceles triangle structure formed on the second tooth 901 is placed in the insertion groove formed between the two adjacent first teeth 801. When the second tooth 901 is subjected to the inclined extrusion force, the second limiting ring 9 moves along the axis of the connecting tube 11. When the compression amount of the second spring 20 is at the maximum value, the end of the triangular structure formed by the second tooth 901 is in the same horizontal plane as the end of the triangular structure formed by the first tooth 801. When the first tooth 801 continues to rotate synchronously with the rotation of the first limiting ring 8, the second tooth 901 loses the extrusion force and is then reset by the elastic action of the second spring 20.
