Set of prosthetic attachments for specific sports and play activities for disabled children aged two to ten years. It is a set popliteal lower limb prostheses, which contains five exchangeable options - scooter, snow scoot, skate board, mosaic and jumping stilts. The main idea is based on drafts of the extensions which are compatible with the default stump bearing by using quick coupler. By an atypical movement, this coupler enables quick connection, disconnection or exchange of the individual attachments.
1. Scooter
The first prosthetic attachment is a specially adjusted scooter. Scooters, as a means of transport, are very popular with children. Scooters offer muscle and balance exercising through game. This exercise is especially beneficial for disabled children. The draft contains two main parts. The first part consists of a height adjustable limb extension which can substitute the missing limb. The second part is the scooter’s body. These two parts are interconnected by a ball joint which enables a revolving movement with one degree of freedom. The interconnection is possible by using a pedal clutch.
2. Snow scoon
Based on the previous draft of the prosthetic attachment, there is also the winter type. Snow scoon enables riding in the snow on the principle of a pushbike. This draft also consists of two parts.
3. Jumping stilts
The third prosthetic attachment is jumping stilts. As in accordance to its name, it is an extension developed for jumping for the entertainment purposes. A child using this prosthesis becomes a fully-pledged player amongst its peers. The prosthesis is designed only for the game purposes. It does not serve for the long distance transport. The attachment consists of one piece of material. The shape of this component and the selected material enables springing during the jump.
4. Skateboard
The fourth draft is a skateboard. The prosthetic attachment is specifically designed for paved surfaces. It allows ride induced by rebound. The product consists of two main parts. The first of these parts is a flexible carbon blade and the second part is a plinth, which is part of the skateboard. The carbon blade is rotationally attached with one degree of freedom in the top of the plinth. This solution stimulates the natural movement of the ankle.
5. Mosaic
The last attachment of the prosthetic set is the mosaic. The main idea of this solution is the involvement of creativity and interaction with the prosthesis. The creativity is achieved by the possibility of placing the different segments of the outer shell. These segments can be assembled into abstract or real pictures. The goal of this attachment is the child’s individuality. As a secondary effect, there can be improvement of the social bonds between peers using game with colorful segments. The prosthesis is specially designed for walking and consists of two main parts. The first part is perforated calf extension and the second part is a cover of the prosthetic foot. The accessories of the prosthesis consist of fastening storage box for segments.
The entire set is designed in three basic sizes. The main components are designed primarily from plastic. These plastic parts are constructed by injection into a mold and further blowing of the semi-finished product. These products shall be unified.
The aim of the work was to propose an alternative solution in contrast with the current state of knowledge. When speaking of the visual aspect, contemporary prostheses for children are being solved only as smaller size prostheses for adults. The attempt for diversification reflects only in color or graphic solutions. In my proposal I emphasize on child as being playful and curious. This reflects in the design of the prosthesis itself. Apart from the primary walking function, the prosthetic set enables a secondary function in form of jumping, skipping, riding, etc. The key benefit is the improvement of the quality of life of a disabled child through the way of new possibilities of the child prosthesis and the improvement of the child’s attractiveness, creativity and elimination of social prejudices. The proposal respects the ergonomic and technical requirements of the leg prosthesis.
