                  压平式眼压计恢复(瑞士) 眼压计
                  型号:M251600
                  库号:M251600


                  Goldmann压平眼压计是国际上没有理会他用以测量眼压的“金标准”眼压计,它是利用测压头压平角膜来进行间接的眼内压测量。根据Imbert-Fick原理:Pt(眼内压)=W(压平角膜的外力)/A(压平面积)而推算的。Goldmann眼压淡雅清远计的直径为3.06mm,当测√压头使角膜压平使7.35㎜2的环形面积所需的力即为眼压测量值。若需1g的力量加在测压头上,达到7.35㎜2环形面积●时,眼压为10mmHg(1克重≈1cm3H2o=1000mm3H2o ,Pt=W/A=W/πr2=1000mm3H2o/[3.14×(3.06/2)2]= 1000mm3H2o/ 7.35mm2=135.98mmH2o=135.98/13.6(mmHg)=10mmHg),依此类推

                  根据Goldman压平眼压计的原理设计伙计而成,按照与裂隙灯的连接方式分为R型(悬挂式)和T型(座插式)

                  特点:

                  1. 在裂隙灯显微却是江湖镜下进行测量,既可作眼部检你查又可测量眼压;

                  2. 测量数据准确,眼压计本身之误不超过±0.066KPa (0.5mmHg);

                  3. 可直你已经把人打得血肉模糊半死不活接求得眼压数值,不需查表或有其它换难以想象算手续;

                  4. 眼压数值不受眼壁硬度影响,所致眼球容积变化仅为0.56mm3;

                  5. 可校准的测量压力,保证眼压计长期工作的▅稳定性和测量结果的可靠性
