background knowledge With the continuous development of modern technology, the medical equipment used by doctors is constantly being updated. Take the stethoscope as an example. It was invented by the French doctor Renak in 1816 and consists mainly of wooden hollow straight tubes. Later, it was continuously improved during the clinical application process, but its basic structure changed little, mainly consisting of the pickup part (chest piece), the conductive part (hose) and the listening part (ear piece). Stethoscope types currently include single-use stethoscopes, dual-use stethoscopes, three-purpose stethoscopes, vertical stethoscopes, multi-purpose stethoscopes, and the latest digital stethoscopes. The digital stethoscope uses electronic technology to amplify the body's sound, overcoming the high noise of the acoustic stethoscope. The digital stethoscope needs to convert the electrical signal of the sound of the sound and then be amplified and processed for optimal listening. They are based on the same physical principles as acoustic stethoscopes. The basic goal of a digital stethoscope is to maintain the look and feel of an acoustic stethoscope, but to improve the detection of sound signals. In addition, high-end digital stethoscopes offer new features such as recording and playback, as well as intuitive data display results and display on peripheral displays such as computer monitors. Advanced features enhance the diagnostic capabilities of physicians. The digital stethoscope maintains the shape of the existing acoustic stethoscope while improving performance. The identification ability of the digital stethoscope is divided into three stages. The first stage is for normal or abnormal identification. At present, most digital stethoscopes are still in the first stage. In the second stage, it will determine which disease is based on the different characteristics of the heart murmur. In the third phase, you can record your individual's heart characteristics and trends, build a personal health model, assess your individual's cardiovascular health trends, or evaluate cardiovascular treatment outcomes, and further give recommendations for treatment. . 3M Littmann: The first river to create a digital stethoscope In 2009, 3M Digital Stethoscope was launched by 3M Company (MMM) Medical Products , a world-renowned company with diversified technology and innovation. The advent of this product marks the first major upgrade of the invention in the past two centuries. 3M's 3M Littmann digital stethoscope is the first electronic stethoscope to use Bluetooth technology to wirelessly transmit signals from the heart, lungs and other body organs to a computer used by doctors, and display the sound curve in real time via Cardioscan software. On the computer screen, more accurate disclosure of possible abnormalities in the patient's heart. The software then analyzes the sonic curve and highlights the details of the anomalous portion of the unwanted noise. The doctor can reduce the playback speed by half to analyze the problem more carefully, save the file to the patient's test results, and email it to the cardiologist to confirm the diagnosis. Not only does this system accurately capture dangerous murmurs, but it also reduces the cost of more expensive ECG exams and the need for unnecessary cardiologists. Face-to-face Table Lifting Frame A face to face desk stand is a desk design that usually consists of two tables and a middle stand so that two people can sit on either side of the table and work face to face. This design helps promote teamwork and communication, as two people can easily exchange ideas and discuss issues. Face to face table racks also save space because two people can share a table instead of needing two separate tables. In addition, face to face desk racks can also improve the efficiency of the office, as it can reduce the time for communication and coordination, making the team closer and more efficient.
