Abstract
We developed a toilet-incorporated electric medical bed for bedridden patients, in which a toilet basin, or a commode, is incorporated in the pelvic plate of an electric medical bed. A replaceable toilet seat is located in the mattress of the bed, and toilet basin was tightly attached on the pelvic plate the bed. The excretion slides through a storage tube that angles toward the side of the bed and is automatically collected in a disposable plastic bag. We, however, encountered a problem with testing this newly developed medical bed with the relevant international standard IEC 60601-2-52:2009, or with the corresponding Korean standard KS P 0388:2012--Electrically operated adjustable bed for home care. There was no clear indication in the scopes of the above standards as to whether this standard testing method is applicable to an electric medical bed embedded with a commode. We revised the Korean standard KS P 0388:2012 to accommodate the toilet-incorporated medical bed in the scope of the standard and successfully performed the mechanical tests including the durability, impact, and deformation test of the bed, proving that the newly developed toilet-incorporated medical bed is mechanically strong and durable enough to pass the standard tests.
Highlights
Falls by the elderly are caused by physical and mental decline as a result of aging, and about half of them are associated with toileting [1,2,3]
The excrement collected in the excretion collection cup was drawn to a fluid waste storage container inside a main body that is placed near the bed through a connecting tube
There were questions regarding whether the mechanical testing method of KS P 0388:2012 could be applied to this product, as the opening of the toilet basin overlapped with the positions of the load pads used in the durability, deformation, and impact tests of KS P
Summary
Falls by the elderly are caused by physical and mental decline as a result of aging, and about half of them are associated with toileting [1,2,3]. The system has been commercialized in Japan and Korea with limited acceptance by the patients and carers, as it has some inherent disadvantages [5,6], such as inconvenience for the patient, as the patient has a difficulty in turning his/her body with the bulky excrement collection cup in between the thighs and cleaning difficulty as the channel between the collection cup and the storage container is long and narrow These problems could be overcome if an excrement collection device were placed under the mattress below the patient buttock, and if the channel between the collection part and the storage part were wide enough, and developed a toilet-incorporated electric medical bed that suffices both the conditions and previously reported a case study of the new system [7,8,9,10,11,12].
