Project 1 - Design and Development of Crutch ( Medical Technology)
Task 1 :
Crutches are a type of walking aid that serve to increase the size of an individual's base of support. They transfer weight from the legs to the upper body and are often used by people who cannot use their legs to support their weight (from short-term injuries to lifelong disabilities).
There are three types of crutches: axilla crutches, elbow crutches and gutter crutches.
Medical crutches are used by individuals who cannot use their legs to support their weight due to some form of disability. There are various types of crutches such as forearm, leg, underarm, platform, and others which help transfer weight from the lower part of the body to the upper part. These are used normally in cases of arthritis, fracture, walking impairment, developmental disabilities, balancing problems obesity among others. The crutches provide more self-confidence and self-dependence to persons facing difficulties in moving.
The high prevalence of osteoporosis & arthritis and the rise in awareness & adoption of crutches are expected to drive market growth during the forecast period. In addition, factors like technological advancements in medical crutches, an increasing number of initiatives & funding by international organizations and governments, and an increase in the number of post-surgery rehabilitation programs are expected to boost the market growth. Moreover, the rise in the geriatric population and the increase in the number of hip, knee and joint replacement surgeries are the other factors that drive the growth of the market.
Task 2 :
All crutches should undergo proper fitting to the user to avoid serious injury.
- That they are easily adjustable, strong and durable
- Have a low deformation risk and high abrasion resistance
- Be made from a lightweight material
- The tips of the crutch should be durable, non-slip and replaceable
- Parts must be replaceable and made from materials that withstand the environment of use
Task 3 :
Concept of operation for the product: There are several easy methods for making your crutches more comfortable, including learning how to cushion them, using cushioning grips, properly using and adjusting your crutches, and even finding a more comfortable alternative.
Work breakdown structure (WBS) of Crutch:
interface control documents
- Mechanical interface- The crutch is all Mechanical parts which will be assembled before use.
- Electrical interface-no need
- Information flow interface-no need
- Human-machine interface-no need
Task 4 :
- Also Better grip for lubricant spilled floors
- Handle with grip and padded with material
- Designed with Three legs.
- Also very safe for Heavy weight people.
- Market is for all old people, disabled people, People with sever injuries in legs and hips or Recently operated Patients.
- Cost effictive
Task 5 :
- Simplicity: It will be having a single rod type structure with three legs below for more stability along with a handle with Better grip facility.
- Immediate intuition: A two wooden rod like structure with a wooden part in between for support.
- Approachable innovation: It should have grip in the lower section so that it dont skid/slip on water or oil.
- Aesthetics: It should look simple so that old age people don't feel awkward.
- Ergonomics: The crutch handle should be Padded so that it will be good for grip as well as the user will be more comfortable.
