Innovative Folding Bed cum Chair based on IoT-Cloud Technology

Aim: The method of utilization of IoT and other evolving techniques in medical equipment design field is discussed in the present paper. A remotely managed interface equipped in a wheel chair cum bed is embedded for elderly or physically challenged people. With the help of a camera embedded in the proposed solution a real time remote monitoring of the patient is achieved using a android application over the concerned person. For achieving the above said purpose, the use of linear actuators has been done. This paper further aims to explore the hidden potentials of merger of all these fields to benefit the end users. Objectives: Remote monitoring of health of the patient through a cloud based android application. Automatic adjustment of the wheelchair into bed and vice-versa. Automatic stool passing chamber facility is available under the proposed model. Injuries during transportation of the patient from one chair to another (or chair to bed) have been limited in our designed model. Methods: The basic mechanism of proposed wheelchair has been designed using the computer aided design software. The basic methodology adopted for development of prototype & subsequent “user review analysis” is displayed below. The CAD Model of the wheelchair cum stretcher was designed using the “Solid works solid modelling techniques”. The basic structure has been designed with several modifications when compared to the conventional wheelchair design. The computer made design was then utilized for final fabrication of prototype. The prototype was tested for endurance, Load bearing capacity and customer comfort during various phases of development. The feedbacks of several subjects were recorded for future utilization in improved design & fabrication Results: The proposed model is of utmost importance as the number of critical patients like accident cases, critical pre and post-surgery cases are increasing day by day. Sometimes these patients need in-time medication during transition in ambulance either picked up from house or are referred to nearby big hospitals. During transition or in hospital critical patients can be handled efficiently by a specialist doctor through his/her smart phone applications. It also optimizes the services of specialist doctors as we find the shortage of specialists in Indian hospitals. In a nutshell, this Wheel Chair system can be moved anywhere due to it portability. Following are the most highlighted features: 1. Authorized relatives and Doctors can see and interact with the patient at any time remotely on his/her smart phone. 2. Authorized relatives and Doctors can see the Vital Sign of patient like BP, ECG, and Pulse etc. at any time through Smart Phone. 3. Doctor can instruct the care taker to release the emergency drugs through Infusion Pump. 4. Doctor can plan the exceptions, drug infusion, alarm etc. 5. System is portable and can easily be shifted to ambulance. All transmissions are wireless so there is no hassle of wires and connectivity. Conclusion: The presented work is limited to the design and fabrication of a new model of wheelchair, which works as a stretcher and has the locomotive capabilities. The key feature of design is its versatility and adaptability to various working conditions. The feedback obtained from various subjects during the testing of wheelchair shows their confidence and fair degree of comfort which they felt while using the wheelchair. The easy and user-friendly use of android application helps to monitor the health of the patient. The smart phone camera helped to achieve this data. The analysis of the data can be done in the cloud base station. Linear actuator has proved to be the low cost and highly reliable equipment to propel the wheelchair.
