Description

Technical Field

[0001] The present invention relates to the technical field of physiology teaching, in particular to a non-invasive human physiology teaching device. Background Art

[0002] Physiology, a major branch of biology, studies the various life phenomena of living organisms, particularly the functions of their components and the internal mechanisms that enable these functions. Physiology can be divided into microbial physiology, plant physiology, animal physiology, and human physiology, depending on the subject of study. Physiology generally refers primarily to the physiology of humans and higher vertebrates, and basic medical physiology instruction refers to human physiology.

[0003] According to the utility model patent of publication number CN220212931U, a non-invasive human physiology teaching experimental equipment includes a vest main body, which includes a front piece and a back piece. The front piece is provided with a mounting block at the chest, and the inner side of the mounting block is sewn with a fleece Velcro. It also includes a mounting sleeve, one side of the mounting sleeve is provided with a mounting cavity for installing an ECG button, and the other side of the mounting sleeve is sewn with a hook-surface Velcro that is compatible with the fleece Velcro. The ECG button can be attached to the mounting block through the mounting sleeve, and the ECG point can be flexibly changed according to the wearer's body shape, thereby ensuring the accuracy of the ECG point positioning, that is, ensuring the accuracy of the clinical diagnosis results. By installing the NFC patch in the airbag bag, the airbag bag can provide cushioning when it is hit, thereby effectively protecting the NFC patch.

[0004] Although the above technical solution can achieve accurate positioning by adjusting the ECG button left and right, in actual use, since the size of the vest body remains unchanged, the vest body will become an obstacle for users of different body shapes, making it difficult to ensure the accuracy of ECG point positioning and inconvenient to flexibly adjust the position of the ECG button. Summary of the Invention

[0005] The purpose of the present invention is to provide a non-invasive human physiology teaching device that is not limited by usage conditions, is not only suitable for users of different body shapes, but also can ensure the accuracy of ECG point positioning through flexible adjustment of its position.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A non-invasive human physiology teaching device comprises a baseband with a flexible setting and an electrode sheet detachably connected to the baseband. Connecting belts are provided on both sides of the left and right sides of the baseband to cooperate with fixing it. The connecting belt comprises an elastic belt with a hollow setting and connecting cloths respectively provided at the free ends of the elastic belt. The connecting cloth corresponding to one side of the baseband is wedge-shaped. A pressure component cooperating with the corresponding connecting cloth is provided on the inner wall of the other side of the baseband. A slot arranged along its length direction is opened backward through the middle position of the front end of the outer wall of the baseband. The inner wall of the slot is cooperated with a guide frame connected to the baseband and capable of deformation. The guide frame is slidably connected to a sliding component cooperating with it and clamped to fix the electrode sheet. The electrode sheet is detachably connected to the sliding component.

[0007] By adopting the above technical solution, when using, first install the electrode sheet on the sliding component, then fix the baseband at the user's chest position, and at the same time appropriately adjust the upper and lower positions of the baseband so that the notch corresponds to the user's precordial area, and then preliminarily fix it through the connecting belt, so that the wedge-shaped connecting cloth is located at the upper end of the other connecting cloth. When fixing, do not let the baseband exert a large pressure on the user's body surface, and then connect the electrode sheet with the corresponding medical instrument for use, and at the same time adjust the position of the sliding component in the guide frame so that the electrode sheet corresponds to the user's heart position, and then apply pressure to the baseband through the pressure component to make the electrode sheet in close contact with the user's body surface, and then perform an electrocardiogram test on the user. If necessary, the user can also be tested at other positions through the position of the twelve-lead electrocardiogram to complete the teaching work, and the hollow elastic band can facilitate the installation and fixation of other electrode sheets.

[0008] The present invention is further configured as follows: the pressurizing component includes an elastic airbag, an air inlet pipe arranged at one side of the bottom of the airbag and connected thereto, and an inflatable and deflable balloon installed at the lower end of the air inlet pipe.

[0009] By adopting the above technical solution, the pressure applied by the baseband to the electrode sheet can be appropriately adjusted by inflating the airbag, so that it can be in close contact with the user's body surface while avoiding excessive pressure that affects the test data and thus affects the teaching effect.

[0010] The present invention is further configured as follows: a suede Velcro is provided on the inner wall of the connecting cloth on one side of the base belt, and a hook Velcro is provided on the outer wall of the connecting cloth on the other side, for use with the suede Velcro.

[0011] The present invention is further configured as follows: the sliding assembly includes a slider, a fixing groove opened at the rear end of the outer wall of the slider, limiting plates respectively arranged at the front and rear ends of the slider, a fixing spring plate arranged at the upper end of the inner wall of the fixing groove and arranged in an arc shape, and a through groove opened at the lower end of the fixing groove and connected thereto.

[0012] By adopting the above technical solution, the electrode sheet can be quickly installed and fixed, and after the fixation is completed, it can also be driven to move along the guide frame to achieve flexible position adjustment, and the position adjustment can be completed without disassembling the baseband.

[0013] The present invention is further configured as follows: a pressure sensor is installed at the bottom of the inner wall of the fixing groove, a spacer is provided at the rear end of the pressure sensor, and a connecting wire is provided at the front end of the outer wall of the pressure sensor to electrically connect with the pressure sensor and extend from the front end of the outer wall of the slider.

[0014] By adopting the above technical solution, the pressure applied by the baseband to the sliding component can be accurately controlled through the pressure sensor, thereby preventing the baseband from applying too much or too little pressure on it, thereby affecting the accuracy of the test teaching results.

[0015] The present invention is further configured as follows: a permanent magnet for adsorbing and fixing the electrode sheet is installed at the rear end of the spacer.

[0016] The present invention is further configured as follows: anti-slip strips cooperating therewith are provided at both upper and lower ends of the inner wall of the base belt along its length direction.

[0017] In summary, the present invention has the following beneficial effects: First, the present invention is not limited by usage conditions and is not only suitable for users of different body shapes, but also can ensure the accuracy of ECG point positioning through flexible adjustment of its position; Secondly, in actual use, the present invention can flexibly adjust the position of the electrode sheet without untying the baseband, thereby facilitating the rapid positioning of ECG points and improving the accuracy of test and teaching results; Third, the combination of the pressure sensor and the pressurizing assembly of the present invention can accurately and flexibly adjust the pressure applied by the baseband to the sliding assembly, thereby finding the appropriate pressure value between the electrode sheet and the user's body surface, thereby improving the teaching effect.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0022] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0023] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections, direct connections, indirect connections via an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0024] Example, see Figure 1-4A non-invasive human physiology teaching device comprises a baseband 1 with a flexible configuration, an electrode sheet 54 detachably connected to the baseband 1, an anti-slip strip 16 cooperating with the upper and lower ends of the inner wall of the baseband 1 along its length direction, and a connecting belt 11 cooperating with it is provided on the left and right sides of the baseband 1, the connecting belt 11 comprises an elastic belt 12 with a hollow configuration, and connecting cloth 13 respectively arranged at the free ends of the elastic belt 12, the connecting cloth 13 corresponding to one side of the baseband 1 is wedge-shaped, a suede Velcro 14 cooperating with it is provided on the inner wall of the corresponding connecting cloth 13 on one side of the baseband 1, and a hook Velcro 15 cooperating with the suede Velcro 14 is provided on the outer wall of the corresponding connecting cloth 13 on the other side, and a pressure component 2 cooperating with it and controlling the pressure applied by the baseband 1 to the user's body surface is provided on the inner wall of the corresponding connecting cloth 13 on the other side of the baseband 1.

[0025] The pressurizing component 2 includes an elastic airbag 21, an air inlet pipe 22 arranged on one side of the bottom of the airbag 21 and connected thereto, and an inflatable and deflable balloon 23 installed at the lower end of the air inlet pipe 22. A control valve connected thereto is installed between the balloon 23 and the air inlet pipe 22, and a one-way valve connected thereto is installed at one end of the control valve. A slot 3 arranged along its length direction is opened backward through the middle position of the front end of the outer wall of the base band 1, and the inner wall of the slot 3 is provided with a guide frame 31 connected thereto and capable of deformation. The guide frame 31 is slidably connected to a sliding component 4 that is engaged with it and is used to fix the electrode sheet 54.

[0026] The sliding assembly 4 includes a slider 41, a fixing groove 43 opened at the rear end of the outer wall of the slider 41, a limiting piece 42 respectively arranged at the front and rear ends of the slider 41, a fixing spring piece 44 arranged at the upper end of the inner wall of the fixing groove 43 and arranged in an arc shape, and a through groove 45 opened at the lower end of the fixing groove 43 and connected thereto. A pressure sensor 5 is installed at the bottom of the inner wall of the fixing groove 43 to match it, a spacer 51 is provided at the rear end of the pressure sensor 5, and a permanent magnet 52 for adsorbing and fixing the electrode sheet 54 is installed at the rear end of the spacer 51. The front end of the outer wall of the pressure sensor 5 is provided with a connecting wire 53 that is electrically connected to the front end of the outer wall of the slider 41, and the electrode sheet 54 is detachably connected to the fixing groove 43 of the sliding assembly 4.

[0027] Instructions for use: When in use, first install the electrode sheet 54 on the sliding assembly 4, so that the electrode sheet 54 is located in the fixed groove 43 of the slider 41, and the permanent magnet 52 on the spacer 51 is used to adsorb the electrode sheet 54, and the electrode sheet 54 is fixed in the fixed groove 43 through the cooperation of the fixed spring piece 44. The wire of the electrode sheet 54 can extend downward through the through groove 45, and then fix the baseband 1 to the user's chest position, allowing it to pass around the user's back, and then the velvet Velcro 14 and the hook Velcro 15 on the connecting cloth 13 can complete the preliminary fixation of the baseband 1, so that the wedge-shaped connecting cloth 13 is located at the upper end of the other connecting cloth 13. When fixing, do not let the baseband 1 exert a large pressure on the user's body surface, and then appropriately adjust the upper and lower positions of the baseband 1 so that the notch 3 corresponds to the user's precordial area, and then the electrode sheet 54 is connected to the corresponding medical instrument for use, and the pressure sensor 5 is connected to the teaching instrument through the connecting line 53.

[0028] Then adjust the position of the sliding component 4 in the guide frame 31, and drive the electrode sheet 54 to slide through the slider 41 so that it corresponds to the user's heart position. Then, apply pressure to the base band 1 through the pressurizing component 2, and generate airflow by squeezing the balloon 23. The airflow enters the balloon 21 through the air inlet pipe 22 and causes it to expand and deform. The base band 1 applies pressure to the sliding component 4 and the electrode sheet 54 through the elastic band 12, so that the electrode sheet 54 is in close contact with the user's body surface, thereby improving the stability between the base band 1 and the user's body surface, and the anti-slip strip 16 can prevent the base band 1 from sliding down.

[0029] Due to the interaction of forces, the pressure applied by the baseband 1 to the electrode sheet 54 will be recorded in real time by the pressure sensor 5, which not only facilitates the teaching work, but also allows the user to know the optimal pressure value between the electrode sheet 54 and the user's body surface. The user can then undergo an electrocardiogram test. If necessary, the user can also be tested at other positions through the position of the twelve-lead electrocardiogram to complete the teaching work. The hollowed-out elastic band 12 can facilitate the installation and fixation of other electrode sheets 54. After use, the gas in the airbag can be discharged through the control valve.

[0030] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
