痛点/Problem
高流量呼吸湿化治疗仪（简称“高流量”）是一种新的呼吸支持设备，
广泛应用于轻中度单纯低氧性呼吸衰竭（Ⅰ型呼吸衰竭）。
相比于传统氧疗、无创通气和有创通气，高流量的优势在于可以给患者提供相对恒定的吸氧浓度（21%~100%）、
温度（31~37 ℃）和湿度（8~80
L/min）气体，并通过鼻塞进行氧疗，为患者提供很好的舒适性。
经过调研，医生反馈当前的一代高流量（下图）屏幕较小且为水平放置，导致医生在手术时或病床远端无法快速查看数据，使用不便。
HFNC is a new respiratory support device, which is widely used in type I respiratory failure. Compared with traditional oxygen therapy, non-invasive ventilation and invasive ventilation, the advantage of HFNC is that it can provide patients with relatively constant oxygen concentration (21%~100%), temperature (31~37 ℃) and humidity (8~80 L/min) gas, and oxygen therapy through nasal congestion, which is very comfortable for patients. Through research, doctors reported that the current HFNC device has a small screen and is placed horizontally, which makes it inconvenient for doctors to quickly view data during surgery or at the far end of the bed.
解决方案/Solution
1. 屏幕尺寸变大：由当前的7寸变为15寸。
Larger
scree size: 7 inches to 15 inches.
便于医生进行手术或查房时，在远端（约2米处）即可看到屏上数据。
It is convenient for doctors to see the
data on the screen remotely (about 2 meters away) when performing
surgery or ward rounds.
2. 屏幕由横屏变为竖屏。
Larger scree
size: 7 inches to 15 inches.
在仪器较多的病房或ICU，竖屏相较于横屏更节省空间。
In a ward or ICU with many instruments, a
vertical screen saves more space than a horizontal screen.
3. 监测数据由4个增加为9个，引入新功能。
The
number of monitoring data increase from 4 to 9, and add new
functions.
丰富大屏的内容显示，提升临床使用体验。
The requirements are clearly hierarchical,
the interaction method is simple and conforms to the doctor's
operating habits.
设计难点/Design difficulties
1. 庞大的数据和功能下，要求层级不多于3个，操作者学习成本低。
1. With huge data and functions, the
number of levels should not exceed three, and the learning cost
for operators should be low.
2. 全部为专业医学用语（术语、图表数据等），需理解后才能设计。
2. All are professional medical terms
(terms, chart data, etc.), which need to be understood before
designing.
3.
交互逻辑要对应医生日常操作习惯，UI设计要满足医疗器械法规要求（颜色、参数名称等）。
The
interaction logic should correspond to the habits of doctors, and the UI design should meet the
requirements of medical device regulations (color, parameter
name, etc.)
