Technical Field

[0001] This utility model relates to the field of sensor testing technology, specifically to a human vital sign signal simulation generator. Background Technology

[0002] With the rapid development of modern medical technology, devices for monitoring human vital signs are constantly emerging. Before these monitoring devices can be marketed, a large amount of test data is needed to calibrate their algorithms and perform deep learning. An important source of this large amount of test data is testing based on analog vital sign signal generators.

[0003] Existing medical device testing equipment typically uses signal injection methods, which often result in single signals and make it difficult to modify related parameters. This makes it challenging to realistically simulate human physiological signals, hindering the testing phase during equipment production. Consequently, existing human biosignal generators suffer from low accuracy, poor real-time performance, inconvenience, and limited application scenarios. Utility Model Content

[0038] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] like Figure 1-5As shown in the figure, the utility model provides a human body sign signal simulation generator, which includes: a profile frame 1, a bottom plate 2, a robotic arm module 3, a motor 4, a pressing plate 5, a loading platform 6, and a controller 7. Among them, the profile frame 1 constitutes the overall structure of the simulation generator of the utility model. The bottom plate 2 is horizontally laid on the profile frame 1 and fixed together with it. The robotic arm module 3 is vertically arranged in the space of the profile frame 1 and is located above the bottom plate 2. The motor 4 and the robotic arm module 3 cooperate to form a driving device, which drives the pressing plate 5 to move vertically above the loading platform 6. The loading platform 6 is regularly arranged on the upper surface of the bottom plate 2 and is used to load the sensor 8. The controller 7, as the control device of the simulation generator, is used for the operation of the system software, the sending of instructions, the collection of data, the transmission of data, the screen display, etc. The controller 7 is embedded between the bottom plate 2 and the profile frame 1.

[0041] For the human body sign signal simulation generator of the utility model, the motor 4 and the robotic arm module 3 drive the pressing plate 5 to move regularly on the sensor 8, thereby simulating the human body sign signal. When the motor and the robotic arm module drive the pressing plate 5 to make regular reciprocating up and down movements on the sensor 8, the human body breathing signal can be simulated; when driving the pressing plate 5 to make regular small-amplitude vibrations on the sensor 8, the human body heart rate signal can be simulated; when driving the pressing plate 5 to make vibrations at a specific frequency on the sensor 8, the human body snoring signal can be simulated.

[0042] Furthermore, as Figure 2 shown, the profile frame 1 includes a bottom plate frame 101, a cross beam 102, and a column 103 built by several profiles through L-shaped connectors 11. Among them, the bottom plate frame 101 is used to support and install the bottom plate 2, and the bottom plate 2 is horizontally laid above the bottom plate frame 101. The shape of the bottom plate frame 101 is not limited. As Figure 2 shown, in one embodiment, four profiles are used to form a rectangular bottom plate frame, and the rectangular bottom plate frame is fixed by L-shaped connectors 11. In another embodiment, seven profiles can be used to form a bottom plate frame in the shape of a "field".

[0043] Among them, the cross beam 102 is fixed under the bottom plate frame through several first corner codes 12. The cross beam 102 extends outwards, extending beyond the area of the bottom plate 2, and is fixedly connected to the column 103 through L-shaped connectors and the first corner codes 12. The column 103 is vertically fixed at the upper end of the cross beam 103 through L-shaped connectors and corner codes, and is vertically arranged in the space of the bottom plate frame through the cross beam 103.

[0044] Furthermore, the L-shaped connector 11 can be an L-shaped connecting plate or an L-shaped corner code.

[0045] Furthermore, as Figure 2As shown, four cushioning feet 9 are installed at the four corners of the base plate frame via foot cup fixing parts 91. The cushioning feet 9 are height-adjustable feet, and by adjusting the height of the cushioning feet, the base plate 2 is ensured to be level. The screw at the upper end of the cushioning feet 9 is fixed in conjunction with the foot cup fixing parts 91, and the base plate at its lower end is made of cushioning material or is equipped with a cushioning pad, thereby avoiding or reducing the influence of external environmental vibrations on the test results.

[0046] The shape of the foot cup fixing member 91 is not limited. The foot cup fixing member 91 includes a threaded hole that mates with the buffer foot cup 9. The foot cup fixing member 91 is fixed to the four corners of the base plate frame by bolts or other fasteners.

[0047] like Figure 3 The diagram shows the specific structure of the robotic arm module 3. The robotic arm module 3 includes a linear screw module 31, an adapter plate 32, and an adapter arm 33. The linear screw module 31 further includes a housing 3101, a sliding plate 3102, and a limit sensor assembly 3103. A ball screw is installed inside the housing 3101. A motor 4 passes through the housing 3101 and drives the screw of the ball screw inside to rotate. The rotating screw converts the rotational motion of the motor into linear motion, thereby driving the sliding plate 3102 to slide up and down.

[0048] Furthermore, the slide plate 3102 is fixedly connected to the nut of the ball screw, and extends out of the outer shell 3101 to be fixedly connected to the adapter plate 32, thereby driving the adapter plate to make linear motion through the motor 4.

[0049] Furthermore, the adapter plate 32 is fixedly mounted on the front end of the slide plate 3102, and the motor drives the adapter plate 32 to slide up and down synchronously via a ball screw. The adapter arm 33 is perpendicular to the adapter plate 32 and fixedly mounted on the front end of the adapter plate 32, used to connect the pressure plate 5. The motor 4 drives the slide plate 3102 to slide up and down via a ball screw, and the slide plate 3102 drives the pressure plate 5 to slide up and down above the sensor 8 synchronously via the adapter plate 32 and the adapter arm 33, thereby realizing the simulation of human vital signs signals.

[0050] Furthermore, such as Figure 4 As shown, several holes are vertically arranged on the adapter plate 32, forming corner code limiting strip holes 3201 and adapter arm limiting strip holes 3202. Among them, there is one corner code limiting strip hole 3201, and the adapter arm limiting strip holes 3202 are arranged on the left and right sides of the corner code limiting strip hole 3201.

[0051] Furthermore, the adapter arm limiting strip hole 3202 is used for bolts to pass through the rear end of the adapter plate and engage with the adapter arm 33 at the front end of the adapter plate, thereby fixing the adapter arm 33 to the front end of the adapter plate 32. Correspondingly, the rear end of the adapter arm 33 is regularly provided with threaded holes for engaging with bolts at the position of the adapter arm limiting strip hole 3202.

[0052] Furthermore, the corner bracket limiting strip hole 3201 is used for bolts to pass through and cooperate with the second corner bracket 13 to fix the second corner bracket 13 above and below the adapter arm 33, thereby supporting the upper and lower parts of the adapter arm 33 through the second corner bracket 13 and improving the stability of the adapter arm.

[0053] Furthermore, the upper and lower surfaces of the adapter arm 33 are regularly provided with corresponding fixing slots at the positions of the corner code limiting strip holes 3201.

[0054] The corner code limit barcode 3201 and the adapter arm limit bar hole 3202 facilitate the installation of the adapter arm and the quick and easy adjustment of the adapter arm's vertical position.

[0055] like Figure 1 As shown, the pressure plate 5 is fixed to the lower end of the adapter arm 33, and the pressure plate 5 is positioned directly above the stage 6 via the adapter arm 33. To avoid or reduce damage to the sensor 8 on the stage 6 caused by the pressure plate 5, a buffer layer 51 is regularly provided on the lower surface of the pressure plate 5. The material and thickness of the buffer layer are not limited, but a buffer pad with elastic material or a foamed elastic material is preferred.

[0056] Furthermore, the stage 6 is regularly positioned below the pressure plate 5. To avoid and reduce the impact of vibrations from the movement of the motor 4 and the robotic arm module 3 on the sensor test results, a buffer pad 61 is regularly provided between the stage 6 and the base plate 2. The material and thickness of the buffer pad 61 are not limited and can be made of the same material as the buffer layer 51.

[0057] Furthermore, the controller 7 includes a housing, inside which are housed a PCB motherboard, MCU, power interface, data interface, communication interface, etc., with the interfaces extending out of the housing for connecting a power adapter and data cable. The controller 7 also features a display screen 71 for display and interaction, which can be fixedly mounted on the controller or rotated to the top of the controller via a rotating component.

[0058] Furthermore, the controller 7 is also equipped with a power switch and control buttons for interaction.

[0059] like Figure 1 and Figure 2 As shown, the base plate 2 has regularly spaced holes to form controller mounting holes. The controller 7 is inserted and embedded between the base plate 2 and the profile frame 1 through these mounting holes. Meanwhile, as... Figure 2As shown, the lower end of the controller 7 passes through the base plate 2 and connects to the upper end of the crossbeam 102, bypassing the base plate frame 101. The crossbeam 102 serves as a support for the controller 7, supporting and fixing it between the base plate 2 and the profile frame 1. The controller 7 does not need to be fixedly connected to the base plate 2 or the profile frame 1 with fasteners; it is directly inserted into the controller mounting hole on the base plate 2 to confine the controller 7 between the base plate 2 and the profile frame 1. Because there are no fasteners for fixing, the controller 7 can be directly installed and removed, which facilitates initial wiring and subsequent maintenance.

[0060] like Figure 5 and Figure 1 The diagram shown is a system schematic of the human vital sign signal simulator of this invention. The power module drives the operation of the breathing controller, heart rate controller, and snoring controller in the controller 7. When the breathing controller sends a breathing frequency signal to the motor, the motor 4 drives the robotic arm module 3 to move the pressure plate 5 in a reciprocating motion, thereby simulating a human breathing signal. When a heart rate frequency signal is sent to the motor 4, the motor 4 drives the robotic arm module 3 to move the pressure plate 5 in a small-amplitude reciprocating motion, thereby simulating a human heart rate signal. When a snoring frequency signal is sent to the motor 4, the motor 4 drives the robotic arm module 3 to vibrate the pressure plate 5 at a specific frequency, thereby simulating a human snoring signal. Finally, the simulated data and the data collected by the sensors are displayed on the controller's screen.

[0061] Furthermore, the aforementioned base plate 2 and pressure plate 5 are made of acrylic sheets. The aforementioned sensor 8 is the sensor to be tested, including but not limited to the sensor body itself, or smart products made based on the sensor body, such as sleep monitoring belts, sleep monitoring needles, etc.

[0062] Furthermore, in one embodiment, the base plate is made of 80*70*1cm acrylic sheet as the structural base plate, which is sturdy, moderate in size, and easy to carry and use for equipment testing.

[0063] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
