Design of Mechanical Device to Transfer a Seriously Ill Person to the Operation Theater

摘要

The problem in transferring a patient from OT table to the stretcher or the transportation system is very common in almost all the hospitals or Operation theatres. Generally, the patient is transferred from the table in the operation theatre to the transporting stretcher or the like manually by hand or lifting the entire bed sheet or bed along with the patient. As we are dealing with seriously ill or injured patients, any kind of disturbances even to a small extent are likely to hurt the patient. So, a device is designed that helps in properly loading/unloading the patient on to/off the table in the operation theatre with minimal use of hands of people. The device to be designed may be semi-manual or semi-automatic or fully automatic keeping the cost that would incur in manufacturing moderate. As per procedure, initially the problem is properly defined and exhaustive search was carried out for different types of ideas or processes for the problem. After that, systematic evaluation of ideas was carried out to select the best idea or process for the product to be designed. Basically, this design is a modification of an existing design with some added features for the stated problem.
