What medical devices are suitable for a 3.5-inch LCD screen?
The application of 3 5-inch LCD screens in medical equipment not only improves the portability and ease of operation of the devices, but also provides clear and accurate display effects for medical staff, which helps to improve the efficiency and accuracy
3.5-inch LCD screens are widely used in various medical devices due to their small, lightweight, compact size, good display performance, low power consumption, high resolution, and durability. The following is a summary of its main application scenarios and related devices:
Vital sign monitoring equipment:
Monitor: Used for real-time monitoring of vital signs such as heart rate, blood pressure, and blood oxygen saturation of patients. The 3.5-inch screen can clearly display dynamic waveforms and values, making it easy for medical staff to quickly determine the patient's status. The 3.5-inch LCD screen of the blood pressure monitor can clearly display blood pressure values, making it easy for medical staff to quickly read the data.
Thermometer: It intuitively displays the temperature value, making it convenient for medical staff to record and observe changes in the patient's temperature.
Electrocardiogram (ECG): Display electrocardiogram waveform, high-definition screen (such as 800 × 480) can present finer curves, assist doctors in accurately diagnosing heart problems, and display real-time electrocardiogram waveforms to help doctors detect abnormal situations in a timely manner.
Spirometer: displays lung function test results, such as forced vital capacity (FVC) and other indicators, for doctors to evaluate respiratory system diseases.
Portable medical devices:
Ventilator: used to adjust and display ventilation parameters (such as tidal volume and respiratory rate), with a 3.5-inch wide temperature design (-20 ℃ to 70 ℃) and high reliability, suitable for complex environments such as intensive care units, making it easy for medical staff to monitor patients' respiratory status.
Handheld portable ultrasound equipment: Some miniaturized ultrasound devices use a 3.5-inch screen to display preliminary images, supporting rapid diagnosis. The compact and lightweight 3.5-inch LCD screen is easy for doctors to carry and operate, and can display ultrasound images clearly.
Portable X-ray machine: Provides convenience for doctors in clinical environments and can quickly display X-ray images.
Oximeter: displays blood oxygen saturation (SpO ₂) and pulse data, with high-definition resolution (such as 640 × 960) to improve data readability, especially suitable for home or portable devices. Real time display of blood oxygen saturation and other data, making it convenient for medical staff to monitor patients' blood oxygen levels at any time.
Other medical equipment：
Small diagnostic device: used to display diagnostic results and related data, assisting doctors in diagnosis.
Medical terminal: As a part of the medical information system, it displays patient information, medical orders, and other content.
Blood glucose meter: The household or portable blood glucose meter often uses a 3.5 inch screen to display blood glucose values and trend charts in high-definition, so as to help diabetes patients clearly display blood glucose values in daily monitoring and facilitate patient self-monitoring.
Infusion pump/infusion pump: displays information such as infusion rate and remaining medication amount, with low power consumption characteristics to extend device life. Medical analyzers, such as blood analyzers, display test results on a screen, and some devices support touch interaction to simplify operations.
Technical features support medical needs
Resolution adaptation: Pu Qing (320 × 240) is used for basic data display, while HD (640 × 960 or higher) is suitable for waveform and image detail presentation. Durable design: Made of stainless steel material, with a wide temperature range (-20 ℃ to 70 ℃) and shock resistant design, suitable for the harsh requirements of medical environments. Interactive function: Some devices are integrated with touch screens, which support medical staff to directly operate the interface and improve efficiency.
The application of 3.5-inch LCD screens in medical equipment not only improves the portability and ease of operation of the devices, but also provides clear and accurate display effects for medical staff, which helps to improve the efficiency and accuracy of medical diagnosis.
Future Trends
With the development of intelligent medical devices, 3.5-inch screens may further integrate higher resolution (such as 800 × 480), wide viewing angle (IPS technology), and lower power consumption, and be applied in more remote medical and wearable devices.
