The present invention relates to a mobile transportation device, and more in particularly to a mobile transportation device convertible to an examination table configured to be transported in a motor vehicle and method thereof.
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 device to facilitate a medical appointment or examination. 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. 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 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 tables, which results in additional costs to both the patients and the medical care facilities.
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.

If the device 10 is placed in a reclined position such that the patient positioned thereon may be in a supine or semi-supine position, a person will then place the device 10 in a lowered seated position for transportation, as represented in an exemplary process block 1002. Once in a seated position with the back of the device 10 raised, a person may remove the device with another person thereon the device 10 from inside a living facility by pushing the handle 38, as represented by block 1004. The process includes transporting and/or wheeling the device 10 carrying a person from inside a nursing care facility to a motor vehicle, as represented by block 1006. Once the device 10 has been wheeled to the motor vehicle, the device 10 is loaded into the motor vehicle by conventional means. For example, the device 10 may be lifted via a wheelchair lift assembly attached with the motor vehicle or pushed up a vehicle ramp. The device 10 is secured to the motor vehicle via a tie down link system that connects to the four tie down links 18 to reduce injuries during transportation from significant movement of the device 10 during a traffic accident, as represented by block 1008. In one embodiment, the tie down link system includes ratchet tie down straps (or other tie down straps) that secure between the tie down links 18 and the motor vehicle to secure the device 10 substantially in place inside the motor vehicle during transportation. The tie down straps may include hooks or other grasping members, that grasp the tie down links 18 for causing a secure connection between the device 10 and the motor vehicle. When appropriate and prior to the motor vehicle's departure, the crash safety bar 310 is positioned with the device 10 as further disclosed herein to increase the structural integrity of the device 10 during transportation in a motor vehicle.
A person will transport the device 10 to a medical care facility, such as a doctor's office, as represented by block 1010. A person will free the device 10 from the motor vehicle by releasing securement members, such as the ratchet tie-downs, from the four tie down links 18, as represented by block 1012. The device 10 is wheeled in a seated position inside the medical care facility, as represented by block 1014. Alternatively, the device 10 may be positioned into a reclined
When appropriate and at a period of time after arriving at the medical care facility, the crash safety bar 310 is released or otherwise removed from the device 10 for allowing the device 10 to transition to an examination table.
At block 1016, a person rolls the device 10 into an examination room at the medical care facility. Once placed into an examination room, the device 10 is positioned from a seated configuration to an examination table, as represented by block 1018. In preparing the patient to be examined, the device 10 is brought from a seated position to reclined position including raising the lower leg receiving portion and lowering the back receiving portion whereby the device 10 is positioned to a desired reclined position, including a flat position, as illustrated in
After the examination, the device 10 is returned to a seated position, as represented by block 1022. When appropriate, the valve lever 216 is rotated for lowering the upper base 16 thereby placing the device 10 in a lowered position. A person will return the back portion to an upright seated position and the locking mechanism for the wheel is released, which allows for a person to push the device 10 via the handle 38.
A person will push the device back to the motor vehicle. At which time, the device 10 is loaded into the vehicle and secured via one or more securement members carried by the vehicle. The device 10 is secured via four points of attachment. The device 10 may be secured at its four points of attachment via on or more tie down straps. When appropriate, the crash safety bar 310 is positioned with the device 10 for maintaining the structural integrity of the back portion during transportation of the device 10 back to the nursing care facility. The wheel locking mechanism 113 is engaged to prevent the device 10 from further moving about the motor vehicle. A person will transport the device 10 back to the nursing care facility, as represented by block 1024. The device 10 is wheeled back into the living facility, as represented by block 1026. The device 10 may be wheeled in either a reclined position or in a seated position.
At block 2028, the patient is laterally transferred to a bed or other structure. Alternatively, the patient may be left on the device 10 inside the living facility.
