Description

  The present invention relates to a bed and a mattress, and more particularly, to a bed and a mattress that allow a user to recognize a sleeping position where the user should lie.

  Conventionally, medical and nursing beds and mattresses have a function of electrically raising and lowering the back bottom and knee bottom to raise the user's upper body on the bed (Patent Documents 1 and 2), continuously. In order to reduce pressure and friction on the skin or internal body tissue of a user lying on a bed or mattress, a pressure ulcer prevention band that is removable from the mattress is used (Patent Document 3).

  In addition to the medical and nursing care fields, a bed (Patent Document 4) provided with an air conditioning function on a side frame and the like, and a function of giving a massage effect to a lying user by providing a vibrator or a sliding roller inside are provided. Beds and mattresses (Patent Document 5) are used.

  Beds and mattresses such as beds and mattresses having a back raising and knee raising function described in Patent Documents 1 to 5 described above, mattresses with removable pressure ulcer prevention bands, beds having an air conditioning function, beds having a massage function, etc. Among the functions that support the operation of the user lying on top or operate or act on the user, there are some functions that do not sufficiently function unless the relative position of the user lying on the bed or the mattress is determined. In particular, the back raising function of the bed and mattress disclosed in Patent Documents 1 and 2 lies on the bed or mattress because the back bottom rotates with respect to the waist bottom with the position of the user's waist as a fulcrum. If the user's position shifts relative to the bed or mattress, for example, in a bedridden patient, there is a shift between the muscle and the skin, and the narrow blood vessels from the muscle to the skin are stretched to occlude the blood vessels. Or it becomes easy to raise | generate a blood circulation disorder and there exists a possibility that the disorder | damage | failure may generate | occur | produce in skin. In addition, when a caregiver returns the body of a bedridden patient whose position is shifted with respect to the bed or the mattress to the original position, the patient cannot move by himself / herself, which is a very heavy burden on the caregiver. Further, even for a user who is not bedridden, there is a possibility that an unpleasant reaction force due to the bending of the bed is applied to the back or thigh, or there is a risk of falling on the bed or falling from the bed.

  For example, Patent Document 6 (Claim 49 (Procedure Amendment Claim 47)) includes, for example, a head portion, a seat portion, and a seat portion so that the bed user's relative sleeping position relative to the bed can be accurately confirmed and adjusted. In a chair bed having a back raising function by rotating the head portion of the bed frame comprising the foot portion at the connecting portion with the seat portion, the joint floor composed of the head portion, the seat portion, the thigh portion and the foot portion ( A chair bed provided with a waist rotation guide at the bottom) is disclosed. According to the chair bed disclosed in Patent Document 6, the waist rotation guide is provided so that the nurse can accurately position the user's waist lying on the mattress placed on the joint floor. It is disclosed that it is possible.

  Further, in Patent Document 7, in a bed having a back raising function in which the angle of the back bottom can be changed with the center portion of the floor as a fulcrum, a scale indicating the length is provided on the side of the back bottom, and is sandwiched on the back bottom. Care is taken of the bed user's head and shoulders on the mattress when the bed user's sciatic tubercle position is positioned at the fulcrum of the angle change by holding the mattress together with the back bottom using an instrument. A bed is disclosed that allows a person to check on a scale.

  Further, in Patent Document 8, in a bed having a fixed waist plate and a back plate, a thigh plate, and a crus plate provided so as to be tiltable with respect to the waist plate, the position of the fixed waist plate on the side surface portion of the bed frame is disclosed. There is disclosed a bed provided with a mark that clearly indicates that it is visible.
