Description

FIELD OF THE INVENTION

The present invention relates to a mobile transportation device, and more in particularly to a mobile transportation device convertible to a Trendelenburg table configured to be transported in a motor vehicle and method thereof.

BACKGROUND OF THE INVENTION

In the past, patients living in nursing home facilities were relatively difficult to transport between the nursing home and a doctor's office or like medical facility due to their advanced age and conditions. The elderly individuals living in nursing care facilities commonly must be lifted by a worker because these elderly are at advanced stages and cannot stand unassisted. These elderly individuals are regular medical patients and frequently visit doctor's offices and other medical facilities.

One particular problem with the prior art systems and methods for transporting elderly patients between their medical visits is that workers must constantly lift and transfer the elderly patients between a host of different seats, cots, and examination tables.

Accordingly, one or more workers, nurses, and others must transfer the elderly patients to different devices to facilitate a medical appointment or examination, including without limitation dialysis appointments to facilitate increased cardiac filling and prompt increase of blood pressure due to the frequent decrease in blood pressure commonly associated with dialysis.

However, elderly patients are susceptible to skin tears, bruising, and bone fractures. The transfer of elderly patients between different devices, such as wheelchairs and examination tables, significantly increases the aforementioned injuries, particularly for patients in need of dialysis. To make matters worse, elderly patients struggle out of fear of being dropped or the lack of dignity associated with the lack of autonomy and dependency of others.

Over time, workers experience injury due to the constant lifting of elderly patients. Costly workman's compensation claims commonly pay workers for back injuries associated with the constant lifting of the elderly patients.

Resultantly, the nursing homes and medical facilities have previously been left with no viable alternatives for safety transporting patients to a doctor's office, including dialysis appointment, without the need for a significant amount of additional equipment and/or staff to transfer the elderly patient between multiple wheel chairs, motor vehicle seats, and examination and procedure tables, which results in additional costs to both the patients and the medical care facilitites.

Accordingly, a need exists for a single transportation device that is configured to safely transport a patient between a living facility, which includes without limitation nursing homes, assisted living facilities, long term care facilities, or other like facilities, and a medical care facility, which includes without limitation doctor's offices, hospitals, dialysis facilities, or other medical treatment facilities. Furthermore, a need exists for a transportation device that allows for a transition to an examination table for examining of a patient in the Trendelenburg position, supine position and/or semi-supine position, and for other improvements that will become evident as the present invention is described in detail below.
