REFERRING TO THE DRAWINGS
[0037] In a preferred embodiment of the present invention, the board (100) shown in FIG. 1 shows the four board parts 101a, 101b, 101c and 101d hingedly joined together by hinges 102 to form the board 100. Each board has a plurality of roller assemblies 200. In a preferable embodiment of the present invention, the board 100 shown in FIG. 1 comprises of roller assemblies 200 consisting of a bracket 201 housing a pin 202, bearings 203 and roller 204. The roller 204 rotates along the axis of the pin 202 as shown in FIGS. 3a and 3b. The roller assemblies 200 are fitted on to the boards by bolts and nuts 205 as shown in FIGS. 3a and 3b for allowing the board to preferably roll laterally. Three such roller assemblies 200 are fitted on the patient's leg side board part 101d and three roller assemblies 200 are fitted on the patient's head side board part 101a. Five roller assemblies 200 each are fitted at the patient's back and thigh side board respectively. The preferred embodiment of the present invention comprises of a washable mattress 300 as shown in FIGS. 4 and 4a which is fixed to the board (100) with the help of four mattress belts 103a that go through the slits 103 on the head side board part 101a and leg side board part 101d as shown in FIG. 4. The mattress 300 is made detachable from the board 100 to wash and sanitize the mattress 300 and also easily service the mechanical parts of the board 100 whenever required. The board 100 and mattress 300 together form the present invention and take the shape of a standard patient cot 500 as shown in FIGS. 5a, 5b and 5c. The board 100 has flexible handles 104a which are attached to the board 100 by slits 104 as well as safety belts 105a which are attached to the board 100 by slits 105 as shown in FIGS. 4, 5a, 5b and 5c as shown in FIG. 4. The present invention can be comfortably worked by a single person by pulling the flexible handles 104a with both hands. The length of the flexible handles 104a have been sized such that distance between the person working the present invention and the patient's cot 500 is comfortably and adequately met to pull the present invention along with the attached mattress 300 and patient safely secured therein onto the stretcher 400 as shown in FIGS. 5a, 5b and 5c.
[0038] The mattress 300 can be adapted to the size of the stretcher 400 as shown in FIG. 4 and FIG. 5c and the size of the cot 500 as shown in FIG. 5a. The board 100 along with the mattress 300 can be fixed and locked on to the patient cot 500 with the help of four locking belts 106a that go through the slits 106 on the head side board part 101a and leg side board part 101d as shown in FIG. 4. The mattress 300 as shown in FIG. 4a has a plurality of foldable parts. The preferred embodiment of the present invention consists of a mattress 300 which as a whole comprises of three sets of foldable parts that are hingedly joined together. The three sets of foldable parts are (i) foldable base parts 301a, 301b, 301c, 301d forming the base of the mattress, (ii) foldable side supports 302a, 302b, 302c and 302d; and (iii) foldable head supports 303a, 303b and 303c. The foldable side supports and foldable head supports are hingedly joined such that they can be upwardly folded and secured in place by the safety belt 105a. Alternatively fasteners may be used to fix the foldable side supports and foldable head supports in their folded position. FIGS. 5a, 5b and 5c show a working example of the present invention wherein the board 100 (not seen) is fixed under the mattress 300. When the patient is on the cot 500 the three sets of foldable parts as mentioned above are in an unfolded position and adapt to the size of the patient cot 500. While being transferred a patient can be nestled within the mattress 300, the foldable parts are secured in the folded position by the safety belt 105 as shown in FIGS. 4a and 5b. The foldable side supports and foldable head supports are used for supporting and securing the patient while being transferred from the stretcher 400 to cot 500 as shown in 4 and FIG. 5c. The present invention can also be used to safely and efficiently transfer the patient from a patient cot 500 to patient cot 500, stretcher 400 to patient cot 500 and stretcher 400 to stretcher 400. The judicious combination of the board 100 and mattress 300 work together in synergy to safely and efficiently transfer the patient as described above.
[0039] In the preferred embodiment of the present invention the board 100 is made to be foldable as shown in FIGS. 2a and 2b so that it will take minimum space to store when it is not in use. Similarly in the preferred embodiment of the present invention the mattress 300 is also made foldable lengthwise by the foldable base parts 301a, 301b, 301c and 301d as shown in FIG. 4c.
[0040] Advantages of Present Invention: [0041] 1. Enables smooth transfer of patient from stretcher to cot, cot to cot and cot to stretcher. [0042] 2. Requires minimum storage space when not in use. [0043] 3. Device does not require electricity and is completely maintenance free.
EXAMPLES
[0044] 1. In a preferable embodiment of the present invention it is placed between the mattress and patient cot, the patient can be easily transferred from the cot to a stretcher, stretcher to a cot and cot to cot. [0045] 2. In another embodiment of the present invention and the mattress are both folded and placed in an ambulance, when an emergency arises the present invention and the mattress are both unfolded the mattress is fixed onto the present invention, the patient is placed on it. The patient can then be lifted from the floor with the help of the flexible handles and placed into the ambulance or onto a stretcher and then smoothly transferred as required. [0046] 3. In another embodiment of the present invention the mattress and the board are non-detachable, they are permanently fixed together to form the present invention. [0047] 4. In another embodiment of the present invention the mattress and the board together roll as per the alignment of the rolling assemblies.
