An intelligent wave-like mattress that could move patients without human labor
Safe Transfers, Gentle Waves, Comfort for Every Patient
Our inspiration
It all begins after a bike accident...
Once during a family dinner, one family member shared about his bike accident. He broke his leg and went through a surgery. After that surgery, he struggled to move. Each time he tried, he experienced intense pain in his leg.
We went through more research...
45% patients are immobile after surgeries. They are mainly orthopedic, abdominal, ICU, and elderly patients. In 1200 immobile patients, 15% of them experiences secondary damages.
Therefore we look for a solution that combines both
The gentle wave like motion
And a mattress
So here is our product
Curawave, Ocean wave comfort mattress
A mattress composed of 360+ silicone units that can automatically move patients smoothly from operating table to their beds.
How does it works
Our product is composed of 360 of these small units
Each unit is composed of a silica base and inflation layer, a confining layer and protective coatings on it. The protective coatings provide anti-infections for a medical environment.
Moving Principle
After inflation, the stretching degree of the restriction layer is smaller than that of the expansion layer, so the silicone will deflect to 1 side. Therefore it can move the object to 1 side.
Here is a overall demonstration of the process
As demonstrated in this video, the strectching degree of the restriction layer and expansion layer are important parameters of our product.
Therefore we need to carefully test and adjust the silicon and other materials like medical gauze in order to satisfy the requirements for our mattress.
How we realize it
1. Mold 3D modeling
These are 2 bases, both top and bottom, and a inner core of 1 silicon unit.
2. Producing the first unit and testing
We use 3D printing to create our mold for the unit. Then, We purchased silicone of different thicknesses to pour according to the mold
We tried thickness of 40A/B, 30A/B, 10A/B and 0A/B. We finally select 30A/B because of its strectching degree and the overall tensile strength of the model.
3. The Control and Programming
The Control
We use solenoid valves to control the in and out of the air flow from the pump to the silicone units.
The Programming
We use Arduino to program the open and close of these solenoid valves and the air pump.
4. Mass production of models
This is the overall combining process of 4 units.
A 1 × 4 model was produced, as shown in the photo.
Through this, the air from the main air pump is divided into four parts, and each group is individually controlled by a solenoid valve.
After producing these models, these models will combine with the air pump and solenoid valves for the overall process testings.
Overall demonstration
After 1 group is inflated, because of the mechanism said before, it will deflect to 1 side. Then the 1 group with deflate and the another group inflate and repeat the process. After a period of half a minute, the object can be moved about 30cm.
We will adjust the power of the mattress for different patients.
What's new
In order to determine the gap in this market, we've done the competitive analysis in this market. Our main competitors are over seas, and there are little competitors in China.
Compare to our product, our main competitors appear with only likeable structures and cannot serves the same functions, and they involves problems like high price and inconvenient to use and sanitize. And they are mainly fragile with un-eco friendly materials.
Our innovations involve reducing reliance on human power, massage function, a price advantage, anti-infection and easy to clean.We will implement AI to create a wound image and calculate the path and force needed. AI will also calculate the appropriate power of the mattress by examining the height, width and weight of the patient.
