RESEARCH
Background
How difficult is it for critically ill patient to get an MRI scan examination? Examination Room with Strong Magnetic Field
For normal patient, walking into the examination room is OK. The patient just need to leave the metal stuffs before getting into the room.
For critically ill patient, because of the strong magnetic field, the metal stretcher must be left outside the room . 3
Without the stretcher, patient need be carried in with the help of nursing workers.
Manual handling activity is really costly and time-consuming for medical staff.

RESEARCH
Exsiting Solution in China
What a hard work for the nursing workers ?
5
A nurse survey report from Shanghai Women Study Association shows that 30.9% of the nursing workers work 9 hours per day, and the other about 70% of workers work 12 hours per day, without weekends, which completely exceed the prescribed statutory working time.
The Weakpoints of Manual Handling In current China's national conditions, many hospitals use large medical imaging equipments still in an overcrowded situation. For the whole medical system, the most simple and affordable way to transfer non-mobile patients is still using manual handling way by nursing workers.
But actually inappropriate manual handling has some potential harm in different aspects in the medical system. For different patients, it may lead to more severe symptoms. And also it may create more burden for medical staffs.
Local vascular puncture caused by bony spur, leads to massive hemorrhage.
Fracture
Myocardial Infarction
Inappropriate Manual Handling
For Patient
For Staff
Ventricular arrhythmia appearring in early time, leads to sudden death.
Cerebral Infarction
accelerate brain metabolism, increase cerebral oxygen demand, and increase the risk of infection.
Attending Doctor
has the responsibility to supervise the whole process in carrying his patients. It's time-wasting.
Nursing Worker
Assist in Manual Handling
need several workers to cooperate in this wor. It's energy-wasting. 6
RESEARCH
Auxiliary Equipment
There are different kinds of auxiliar y equipments to assist the manual handling. They can be classified into 3 movement modes, including lift, translation and turn. They can be helpful, but can not solve the core problem.
Lift Can Lift Heavier Body Complicated Steps

What I Want to Change
How might we transfer unmovable critically ill patient to MRI scan smoothly and safely ? Movement Mode: Translation Can Transfer Patient More Smoothly

Translation, the better way to move patient without sitting up
Design a way to transfer patient for MRI scan. Through the sketches, I tried my best to improve and promote the possible way of realization, and to learn different solution in different areas. Also I made sure that the design obeys the basic medical safety restriction, which can have both the crazy innovation and the possibility of realizing it in real.

MRI TRANSFER
Part 1 Strecher + Part 2 Wheeled Bed 11
MRI Transfer makes the optimization of image services as a starting point and further simplify and standardize the MRI delivery processes of critically ill patients. Replace the existing transport mode of artificial lift, MRI-Transfer uses the convenient moveable way of combining the conveyer belts, universal wheels and supplemented Scoop stretcher structure, so that critically ill patients unable to move, could smoothly complete the medical imaging examination in the most hassle free manner - lying on the back. 12

to MRI bedplate
Push the MRI transfer to fit the MRI machine, and press the button which can raise the bedplate to the height of inspection. Use the conveyor belt again to transfer stretcher holding patient to the MRI bedplate and fix the stretcher with the MRI. finally choose the corresponding coil to fix it with the stretcher and start preset sequence. After the inspection, repeat the process to send patient back.

Seek Pain Point
Nowadays many people work with hands in the fixed position for a long time which is potentially harmful to health. 53
For different parts of arm, certain kinds of high strength hand activities such as typing, using phone and so on may cause several harms.
Finger
Wrist
Elbow
Shoulder
Feel pain and sore in finger joints
Repetitive strain leads to tenosynovitis
Prolonged compression leads to poor circulation
Long time fixed position leads to periarthritis
So cer tain exercise and relaxation of joints of arms are very important. but actually few people could insist it because of lack of Excitation.

DESIGN DESCRIPTION
This is an interactive device aimed to change people's diet circumstance. Contemporary fast paced life makes people have no time to take into account the small details of life, such as the experience of the meal. With heads bowed to phones all family members feel awkward at a meal. So how to make a little change in the dining environment?
73
We give the answer, to combine music and food. Giving pleasant feelings of the two kinds of experience, each one can become better with each other. Using similar morphology of plate and DJing, this design let people touch and rotate the upper part of the DJing, following the rhythm of the music to decrease the embellishment of waiting meals.
