Innovative Folding Bed cum Chair based on IoT-Cloud Technology

Abstract

\n\n The method of utilization of IoT and other evolving techniques in medical equipment design field is discussed in the\npresent paper. A remotely managed interface equipped in a wheel chair cum bed is embedded for elderly or physically challenged people.\nWith the help of a camera embedded in the proposed solution a real time remote monitoring of the patient is achieved using a android\napplication over the concerned person. For achieving the above said purpose, the use of linear actuators has been done. This paper further\naims to explore the hidden potentials of merger of all these fields to benefit the end users.\n\n\n\nRemote monitoring of health of the patient through a cloud based android application. Automatic adjustment of the wheelchair\ninto bed and vice-versa. Automatic stool passing chamber facility is available under the proposed model. Injuries during transportation of\nthe patient from one chair to another (or chair to bed) have been limited in our designed model.\n\n\n\n The basic mechanism of proposed wheelchair has been designed using the computer aided design software. The basic\nmethodology adopted for development of prototype & subsequent “user review analysis” is displayed below. The CAD Model of the\nwheelchair cum stretcher was designed using the “Solid works solid modelling techniques”. The basic structure has been designed with\nseveral modifications when compared to the conventional wheelchair design. The computer made design was then utilized for final\nfabrication of prototype. The prototype was tested for endurance, Load bearing capacity and customer comfort during various phases of\ndevelopment. The feedbacks of several subjects were recorded for future utilization in improved design & fabrication\n\n\n\nThe proposed model is of utmost importance as the number of critical patients like accident cases, critical pre and post-surgery\ncases are increasing day by day. Sometimes these patients need in-time medication during transition in ambulance either picked up from\nhouse or are referred to nearby big hospitals. During transition or in hospital critical patients can be handled efficiently by a specialist\ndoctor through his/her smart phone applications. It also optimizes the services of specialist doctors as we find the shortage of specialists in\nIndian hospitals. In a nutshell, this Wheel Chair system can be moved anywhere due to it portability. Following are the most highlighted\nfeatures:\n1. Authorized relatives and Doctors can see and interact with the patient at any time remotely on his/her smart phone.\n2. Authorized relatives and Doctors can see the Vital Sign of patient like BP, ECG, and Pulse etc. at any time through Smart Phone.\n3. Doctor can instruct the care taker to release the emergency drugs through Infusion Pump.\n4. Doctor can plan the exceptions, drug infusion, alarm etc.\n5. System is portable and can easily be shifted to ambulance. All transmissions are wireless so there is no hassle of wires and connectivity.\n\n\n\nThe presented work is limited to the design and fabrication of a new model of wheelchair, which works as a stretcher and has\nthe locomotive capabilities. The key feature of design is its versatility and adaptability to various working conditions. The feedback\nobtained from various subjects during the testing of wheelchair shows their confidence and fair degree of comfort which they felt while\nusing 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\ncost and highly reliable equipment to propel the wheelchair.\n
