In addition, the patient is repeatedly moved in and out several times a day like an emergency room, If it occurs, bed sheets should be replaced from time to time and hygienic management is required.

A series of bed sheet replacement operations to remove existing bed sheets on a mattress, to lay new bed sheets, and to take out the rolled bed sheets has been carried out all by hand until now, It has the disadvantage of being robust. In addition, in the case of an emergency room in which a struggle is taking place, there is often a situation in which a bed sheet is not replaced in time, and many patients are laid on a bed sheet used by a previous patient. Since the bed sheet is directly contacted with the body part of the patient and the replacement of the bed sheet is not performed in a timely manner as described above, it is difficult to maintain the cleanliness of the patient and the infection of pathogenic bacteria is worried. The blood is exposed to the risk that a patient is infected with a fatal disease such as AIDS.

In addition, it is desirable to replace bed sheets frequently in order to maintain a clean sanitary condition even at home. However, there are disadvantages in that it is difficult to replace the bed sheets by the housewife alone and to wash the replaced bed sheets alone .
