数理教研室最近试制了一种供教学和诊断用的仪器——心音扩大器,受到了内科医生和工农兵学员们的欢迎。 心音扩大器是利用“换能器”将心音换为电能输至晶体管放大器放大,再用“换能器”(喇叭、耳塞),将电能换为声能,供多人听诊,是一种医用教学仪器。 大家知道,心脏和肺部疾病的诊断,要借助听诊器的听诊来鉴别。但如果在教学中许多学员一个一个在病人身上听诊,就会造成病人很大的负担。为了减轻病人的痛苦,满足临床教学的需要,提高教学质量,在系党总支、支部的直接领导下,数理教研室的同志们,以毛
Mathematical teaching and research department recently trial a device for teaching and diagnosis - heart sound amplifier, by physicians and workers and peasants and soldiers welcomed. Heart sound amplifier is the use of “transducer” will heart sound into electrical energy input to the transistor amplifier to enlarge, and then “transducer” (speaker, earplugs), the electrical energy into sound energy, for more than auscultation, is a medical Teaching equipment. We all know that the diagnosis of heart and lung disease should be identified by auscultation of a stethoscope. However, if many trainees auscultate on the patient one by one during teaching, the patient will be greatly burdened. In order to alleviate the suffering of patients, to meet the needs of clinical teaching and improve the quality of teaching, under the direct leadership of the Party branch, branches, mathematical comrades, to Mao
