Thanks to all who responded. First to answer sockov's question, the chair has not had a clinical trial or pilot test yet. But we are looking to do one (an expensive proposition).
I especially want to thank Thanksforthedonuts for the thoughful reply. This is excellent feedback.
My LTC consultant nurses told me patients should be changed every 2 hours but perhaps every 3 hours might be more accurate. This is an excellent point and the video should be updated to reflect this. However this is still a hugely labor-intensive activity for LTC nurses - even at 3-4 hour intervals.
For statement (1), I do not understand. Hoyer lifts are very slow and the by-directional transfer is going to take a minimum of 8 minutes. To build and unbuild the stretcher takes about one minute, and there is little danger of a patient fall, a nursing back injury, and little patient pain involved.
For (2), I completely agree that a $2,000 to 3,000 chair is expensive and money is tight. It is hard to compete with a $150 WC and a $1,000 patient lift that can transfer multiple patients per hour. That is why the chair needs to do a lots of things very safely and efficiently (bed transfer in 2-3 minutes, shower transfer in 30 seconds, commode transfer in 30 - 90 seconds) in order to justify that expense. There is an HCPCS Medicare code for insurance reimbursement for the chair and patients at home could apply for a chair and bring it into LTC in some cases when they can no longer live at home.
For (3), the chair can be used with a high quality foam seat cushion which will limit pressure sores. Most LTC patients I have seen sit on vinyl seats in cheap WCs without cushions - not very comfortable.
For (4), the chair has about the same footprint (viewed from above) as a 18" seat WC but is certainly heavier (50 - 60 lbs.). This is MUCH smaller than a lift combined with a standard WC as far as space required for use. The chair/gurney surface is 24 inches wide and obviously would not work well for patients over 250 lbs. but a 200 lb. patient should be able to be changed easily enough.
Thanks again for taking your valuable time to reply!
