Description

Technical Field

[0001] This invention belongs to the field of medical ultrasound equipment, and specifically relates to a keyboard control method, system and storage medium for ultrasound imaging equipment. Background Technology

[0002] Ultrasound imaging equipment is a medical diagnostic tool that utilizes the properties of ultrasound waves reflecting and propagating inside the human body to generate images through computer processing. It is widely used in obstetrics and gynecology, cardiology, urology, and many other fields. Ultrasound equipment emits ultrasound waves through a probe; when these waves encounter interfaces between different tissues, they produce echoes. The equipment receives these echoes and constructs an image based on the timing and intensity of the echoes. Ultrasound imaging is non-invasive, safe, real-time, and cost-effective, making it an indispensable part of modern medical diagnosis.

[0003] Existing ultrasound equipment keyboards typically contain multiple scattered keys, each used for different functions. Ultrasound images are crucial for doctors' diagnoses, and during operation, doctors frequently need to use key combinations to save, play back, edit, and perform other operations on images and videos, undoubtedly increasing operational complexity. Furthermore, these scattered keys occupy a significant portion of the keyboard space, affecting the overall compactness of the device and making it difficult for doctors to quickly and accurately locate the required keys, thus impacting work efficiency. This complex design can also lead to misoperation, affecting diagnostic accuracy. Secondly, because each key is independent, the device's appearance design is severely limited, preventing personalized designs.

[0004] Therefore, there is an urgent need for a new type of keyboard control system to enhance the convenience and efficiency of user operation and provide doctors with a better diagnostic experience. Summary of the Invention

[0032] Example 1: Keyboard Control System for Ultrasonic Imaging Equipment

[0033] The keyboard control system of this invention mainly consists of a multi-function button, functional modules, and a microcontroller. The multi-function button of this invention has actuating components including a fingerprint recognition layer, a spring-loaded microswitch, and a knob mechanism. The fingerprint recognition layer is disposed on the surface of the knob mechanism, and the microswitch is disposed at the bottom of the knob mechanism. The central shaft of the knob mechanism is connected to the shaft of the microswitch via a mechanical connector (preferably a bushing or coupling), so that the rotation of the knob does not directly affect the microswitch. An annular groove is pre-drilled at the top of the knob mechanism, and an LED strip is fixed within the groove. A transparent heat-shrink tubing is then used to wrap the connection between the LED strip and the knob. The heat-shrink tubing is heated to ensure it adheres tightly to the knob and the LED strip, thus encapsulating the LED strip.

[0034] The functional modules include: an image freeze / thaw module, a short video acquisition module, an image saving module, a frame rate adjustment module, and a user identification module; the microcontroller includes: a connection module and a storage module. The fingerprint recognition layer's data interface is connected to the user identification module, which is configured to identify the user and retrieve the connection relationships stored in the storage module. The fingerprint recognition layer's data interface is connected to the GPIO pin of the microcontroller (model: STM32F429) for data communication. Next, the knob mechanism and microswitch are connected to another GPIO pin of the microcontroller, and each is programmed to have at least one trigger mode. The LED strip is connected to the microcontroller's PWM pin via a resistor to control the light color change. Fingerprint recognition on the fingerprint recognition layer controls the execution of any functional module (or multiple sequentially executed functional modules); single-click, double-click, and long-press of the microswitch control the execution of one functional module (or multiple sequentially executed functional modules); rotation of the knob mechanism controls the execution of one functional module (or multiple sequentially executed functional modules).

[0035] The execution component is connected to one functional module, or the execution component is connected to at least two functional modules that are executed sequentially. For example, when the single-click mode of the micro switch is connected to an image freeze or defrost module, the image can be frozen or defrosted by a single-click operation; when the double-click module of the micro switch is connected to a short video acquisition module and an image saving module that are executed sequentially, the functions of short video acquisition and image saving can be executed sequentially by a double-click operation.

[0036] The connection module establishes the connection relationship between the execution components and functional modules, enabling personalized settings based on individual user habits. The storage module stores information on the connection relationships between execution components and functional modules stored by at least one user. In software programming, the fingerprint recognition layer is activated when a finger touches a button. After user recognition, the stored connection relationships are retrieved, the user's preset button settings are displayed, and the corresponding function is executed based on the button's operation (single click, double click, long press). Simultaneously, PWM signals control an LED strip to display different lighting effects. All application functions corresponding to each operation can be customized according to user habits. The operation process is as follows: Figure 1 As shown.
