今般では、老齢化が進み老人が多くなってきているのにも関わらず、核家族化 が進み老夫婦又は老人独りで生活しなければならないケースが多くなってきてい るが、老夫婦又は老人独りで生活することは様々な面で困難があり、中でも浴槽 に入ったり、上がったりすることは老人にとって非常に困難であった。そこで、 場合によっては派遣会社に依頼し、その派遣会社から派遣された看護人に浴槽に 入れてもらったり、上がらさせてもらったりしていた。ところが、看護人が老人 を浴槽に入れさせたり、上がらさせたりすることはかなりの重労働であった。 老人が家族と一緒に生活している場合も同様に、家族の人が老人を浴槽に入れ させたり、上がらさせたりしなければならず、看護をする人にとってはかなりの 重労働であった。 また、下半身が不自由な身体障害者の場合も同様に独りで浴槽に入ったり、上 がったりすることが困難であるため、看護する人の手を借りて浴槽に入れてもら ったり、上がらさせてもらったりしているが、看護をする人にとってはかなりの 重労働であった。 In recent years, despite the aging of the population and the increasing number of elderly people, the number of cases where the nuclear family has progressed and the elderly couple or the elderly alone have to live in many cases. It was difficult to do in various ways, and it was very difficult for an old man to enter and leave the bathtub. Therefore, in some cases, I asked the dispatching company to let the nurses dispatched by the dispatching company put them in the bathtub or raise them. However, it was quite hard work for the nurses to put the old man in or out of the bathtub. Similarly, when an old man lives with his family, the family member must put the old man in or out of the bath, which was a considerable heavy labor for the caregiver. Similarly, for physically handicapped people with lower mobility, it is difficult for them to enter the bathtub or go up by themselves. Although I was allowed to raise it, it was quite a heavy labor for those who care.
