Abstract
The aim of the study was to design and develop a comfortable, sturdy and lightweight canine wheelchair prototype. The wheelchair was created for small dogs with paresis or hind limbs paralysis. The final product is adjustable to allow comfortable and customized use and therefore is suitable for more than one patient. Wheelchair implementation in the rehabilitation process improves the dog’s mobility as close as possible to the physiological gait, which may lead to enhanced quality of life or even a return to full fitness after injury. This paper describes the engineering design process to create a ready-to-use product. One of the first steps of the project was to take measurements of two dogs with hind limb paresis caused by mechanical trauma. The range of movement of dogs and their mobility skills were assessed and recorded while walking on various types of surfaces in previously used wheelchairs. Considered together with the review of market solutions, it made it possible to reject design errors that may arise during the design, as well as to introduce improvements that improve the quality of their lives. Three three-dimensional models were designed in compliance with the project assumptions, and next underwent multi-criteria analysis. External company bent and completed the metal parts for the model that received the highest evaluation. Following the tests, the necessary adjustments were done, and two fully operational canine wheelchairs were produced.
