A simple and inexpensive uroflowmeter has been designed that uses a common carbon dioxide cystometer. The patient voids urine in a specially designed container connected at the bottom of the carbon dioxide source in the cystometer. After proper calibration (500 cc fluid for a 20 mm. deflection in the paper) the patient is asked to void while carbon dioxide flows through the container and the paper recording commences. Any change of volume in the container produces a change in the pressure recorded by the cystometer, which will allow us to know, following calibration, the 2 factors involved in flow: 1) volume voided and 2) time. A table of average flow is available for a quick reading of the findings only by superimposing the table on the uroflow study. The only attachment needed for the cystometer is the special container. Our results support the use of this economical new way to determine urinary flow.
一种简单且价格低廉的尿流计已被设计出来，它使用的是常见的二氧化碳膀胱内压测量仪。患者在一个特别设计的容器中排尿，该容器连接在膀胱内压测量仪的二氧化碳源底部。经过适当校准（500立方厘米液体使记录纸产生20毫米的偏转）后，让患者排尿，同时二氧化碳流经容器，记录纸开始记录。容器内体积的任何变化都会使膀胱内压测量仪记录的压力发生变化，校准后这将使我们能够了解与尿流相关的两个因素：1）排尿量和2）时间。只有将表格叠加在尿流研究上，才有平均尿流表格可供快速读取结果。膀胱内压测量仪唯一需要的附件就是这个特殊容器。我们的结果支持使用这种经济的新方法来测定尿流。
