Diagnostics is an important compulsory course for medical students, a bridge connecting basic medicine and clinical medicine, a foundation for learning and mastering various disciplines of clinical medicine, and a key to opening the door to clinical medical work. Physical examination is one of the contents of diagnostics, and percussion is the basic method of physical examination. Every medical student must be proficient in standard percussion techniques. Through study, 30% of the students can master it quickly, and 30% of the students need to be repeated by the teacher. Correction can be mastered, and 30% of students need longer practice to master the correct percussion method. Generally, the density of the tissue in the thoracic cavity is different. The percussion of the lungs is voiceless, the percussion of the heart is solid, and the parts of the heart covered by the lungs are dulled. If the percussion technique is wrong, the percussion sounds will be indistinguishable. The ear can distinguish the change of the sound. The so-called correct technique means that the percussion force should be consistent and the rhythm should be consistent. In addition, the percussion force that is too strong will make the patient uncomfortable, and the force is too light and difficult to distinguish. Based on this, a suitable The percussion trainer not only liberates the teacher's time, but also helps students practice anytime, anywhere, and clearly knows the correct number of times and the wrong number of times during the practice process, until all are correct.
