一、概说在毛主席“应当积极地预防和医治人民的疾病”的光辉思想指引下,我单位研制成了“XJY-3型心脏机能诊断仪”,它是一种能显示人体心电图、心音图和超声心动图的综合性诊断仪。医师通过所显示的波形,进行分析或比较即可精确地诊断出患者的各种病变和程度。这部仪器制成后曾在武汉医学院附属第一、第二医院经过几年临床试用,作过数百病例的超声心动图检查,其中部分病例经手术证实,诊断效果较好。由于它是无损伤性探测,对病人没有任何痛苦,又可任意作重复检查,所以对于判断内外科治疗效果和追踪疾病的自然过程,都有重要的意义,而且费用经济,因此受到医务人员的欢迎,认为无论在临床诊断或是医学研究上,实用价值都很大。现将本仪器在应用超声心动图诊断方面的效果录列如下: I. General Introduction Under the glorious ideology of Chairman Mao’s “diseases that should be actively prevented and managed by people,” our unit has developed “XJY-3 Cardiac Function Diagnostic Instrument,” a device that can display human body electrocardiogram, heart sound Figure and a comprehensive diagnostic echocardiography. Through the displayed waveforms, doctors can accurately diagnose a variety of patients’ diseases and degrees by analyzing or comparing them. After the device was made in Wuhan Medical College Affiliated First and Second Hospital after several years of clinical trials, made hundreds of cases of echocardiography, in which some cases confirmed by surgery, the diagnosis is better. Since it is a nondestructive test, it is painless and repeatable to the patient, so it is of great importance to judge the internal surgical treatment and to follow the natural course of the disease, and is cost-effective and therefore medical staff Welcome, that in terms of clinical diagnosis or medical research, the practical value are great. Now the instrument in the application of echocardiography diagnostic results recorded as follows:
