골든캡슐(Golden Capsule)은 재난 구조 현장에서 환자를 이송할 때 환자의 수액팩을 누군가가 계속 들어주어야 했던 문제를 해결한 응급용 무동력 수액 주입 장치다. 건물 잔해, 여진 등 위험요소로 가득한 현장을 수액팩을 높이 든 채로 이동하는 행위는 구조대원 및 의료진에게 2차 피해를 입힐 가능성이 있다. 또한 구조업무의 비효율이나 구조대원의 체력 저하 문제를 야기하기도 한다.
중력 대신 탄성력과 기압 차이를 이용한 골든캡슐(Golden Capsule)은 높이차를 확보하지 않아도 안정적인 속도로 균일한 수액 주입이 가능하다. 이 과정에서 별도의 전력을 필요로 하지 않아 전력 보급이 어려운 재난 현장에서 적합하게 사용될 수 있다. 또한 주입 속도도 조절할 수 있으며, 기존의 링거와 비교하여 최대속도가 약 150% 향상되었기 때문에 빠른 수액 처방이 요구되는 재난상황에서 더욱 효과적이다.
- Background & Solution -
- How it works? -
Owing to its strong elasticity, the golden capsule can easily reach full-drip speed,
which is often required in emergency situations.
Here are 2 simple steps to start Golden Capsule.
There are two kinds of Golden Capsules: Glucose, and Normal saline.
In many cases two are prescribed together.
- User Scenes -
Like these user scenes, the golden capsule can be fixed to a stretcher or carried by a rescue team.
it can optimise work efficiency for rescuers, because it can be easily fixed to the belt of a stretcher.
- Prototyping -
We made a prototype model using acrylic CNC processing and 3D printing method.
In actual production, it will be made of polycarbonate material for a reasonable price.
- Lo-fi Test -
We confirmed the feasibility of Golden Capsules through lo-fi test.
We can quickly inject fluids or completely stop through a method using balloon and air pressure differences,
and even control the speed as desired.
- Experiments -
The performance of the golden capsule was accurately measured
using a more advanced experimental model.
Experimental proofs:
1. Can be operated for more than 30 minutes
2. Uniform injection speed across all sections
(meets the standard for uniformity of medication injection devices specified by the medical community)
3. Faster than traditional methods using IVs
(often required in emergency situations)
4. Speed adjustable
This video shows a linear change in the rate of infusion as the amount of air entering the shell is controlled.
The faster the speed was set, the faster the water was leaking out.
- Feedback from Medical Experts -
We interviewed medical experts with experience in dispatching to rescue sites.
Interview with doctor Choi Seok Jae at Hwahong Hospital
We presented this project in front of Doctors Without Borders, nurses with 10 years of experience, patent attorneys specializing in design engineering, internal medicine specialists, emergency medicine specialists, mechanical engineering professors, and design professors, and got good feedback.
