Ruijin Hospital is one of the most famous hospitals in Shanghai. Every day many urgent and seriously sick patients sent to the ICU add on nurses' workload.
During the summer camp, the Design School collaborates with Ruijin Hospital to help improve work efficiency with good design.
Our group was assigned to ICU to do investigation and design for them.
Background
Process
Research
Observation
The nurses guided our group a tour around the ICU and introduced their daily tasks to us.
We observed their daily work and how they run the complex medical machines and monitors to take care of the patients.
We found many inconveniences and confusing details and took pictures to record them.
Interview
By asking why they have to do something in an inconvenient way, we gathered several historical restrictions, which our design must apply to.
We interviewed the nurses for more details of their work flow.
Brainstorming&Card Sorting
Do brainstorming to discover problems .
Classify those problems and issues to 3 topics.
Sorted those problems by frequency and urgency.
Efficiency
Nurses need to organize a large number of catheters on the patient
Drainage bag volume needs to be monitored
Intensive care record forms need to be recorded into the system
Patients' relatives' inquiry will hinder the work of medical staff
The nurses have to repeatedly answer same questions
Safety
Blood is prone to leakage during hemodialysis
There is no isolation room between the patient and the visiting relatives, and there may be cross infection.
When cardiac arrest occurs, pressing patients takes time and consumes physical strength.
Patients are unable to flip their bodies with more vulnerable skin, which may cause skin necrosis
The surgical vehicle was pushed to the intensive care unit without prior notice

Journey Map
Problems Defination
After above analysis, we summarized the messy problems and selected 4 main pain points to address:
1 Too much digits to read from the monitors and screens and type into computer system
2 The same questions been asked. The relatives of those patients are usually anxious and worried. They often keep disturbing nurses' workflow by asking for basic vital metric.
3 When the patient performs hemodialysis or puncture treatment, the needle is easy to slip off with the patient's movement, causing leakage or even arterial blood blowout.
4 The drainage , that is used to gather the dialysate, needs manpower to check whether it is full or not, so as to prevent dialysate from flowing back into the patient.
Design
Discussion & Sketch
To address these 4 problems, we discussed together to came up with various ideas.
We decided to :
build an intelligent system to address the data typing problem
and informing relatives problem,
a Drainage Monitor to address the full drainage problem,
a Leakage Monitor to address the leakage problem.
* since I was only responsible for the design of the intelligent system, I will only show the process of designing the intelligent system
