医療グレードのシリコンキーの応用

People often talk about “B-ultrasound”. B-type ultrasound uses the physical properties of ultrasound in human tissue, such as reflection and refraction, to receive signals through specific instruments to display the shape of various tissues and organs, thereby judging the location and nature of lesions. even the extent of functional impairment. Nowadays, the diagnostic information provided by B-ultrasound is more and more accurate and reliable, and the scope of application is more and more extensive, and clinicians are increasingly relying on ultrasound machines. At the same time, each set of B-ultrasound machine must pass through layers of mechanical, functional, high-voltage current resistance, patient simulation and other strict tests before shipment.

As a special-needed instrument often used in clinical medical treatment, B-ultrasound machine has relatively high requirements on the functional properties of each component; and its main operation buttons are often made of silicone material, and the silicone buttons are placed under the plastic shell , on the PCB board; when the medical staff operates on the surface of the control panel, the force directly presses the silicone button layer, which induces the PCB board through the conductive carbon particles on the bottom layer of the button, so as to achieve the operation effect.

What functional effects do the silicone buttons need to have on this application? How does it help the B-ultrasound machine to check and diagnose human tissue? Next, we will explain the application of ES Dongcheng’s medical-grade silicone button on the control panel of the B-ultrasound machine.

1. Long service life and high quality; the usage rate of clinical medical equipment is very frequent, and different people will make appointments and queue up for testing at different times every day; the service life of the silicone button directly affects the service life of the B-ultrasound machine, and Time cost due to equipment replacement. This medical-grade silicone button adopts customized high-life silicone material, and the button has a long life. Quality, Durability. Meet the use requirements of medical grade silicone buttons.

2. Precise conduction and high performance; the sensitivity of the keys not only affects the accuracy of the use of the B-ultrasound machine, but also directly affects the efficiency of the medical staff during the examination process for each patient. The bottom surface of each single key of this silicone keyboard There are at least 4 or more high-quality conductive carbon particles installed according to the position of each trigger point on the PCB board of the ultrasound machine to ensure that the carbon particles maintain long-term and good conductivity, and stabilize the signal transmission between the silicone button and the PCB board.

3. The key characters are clear and wear-resistant; before the users of the ultrasound machine press the plastic keycap with force, they need to determine and familiarize themselves with the functions expressed by the key characters. As the function keys on clinical medical equipment, the technology used for the characters must reach Later use requirements; the surface characters on this plastic keycap adopt laser engraving process, ES Dongcheng’s reliable technology and automatic wear resistance test inspection make the key characters clearly visible, and meet the requirements of wear-resistant and long-life use .

In addition to medical equipment such as B-ultrasound machines that often use high-level medical-grade silicone materials, more and more silicone materials are widely used in real life and daily operations; in terms of single buttons, many electronic products can be seen With the continuous development of modern technology and product personalization, silicone buttons are widely favored because of their strong functionality and good material performance. ES Dongcheng has been focusing on the silicone product industry for many years. Now, it conforms to the requirements of the times. Develop into a one-stop “silicone +” professional service provider to meet the customized requirements of more mid-to-high-end brands for silicone products.
