PARAMOUNT BED CO., LTD.

A fluid mattress is provided with a fluid supply unit, a fluid path, a plurality of first cells connected to each other, a plurality of second cells connected to each other, a plurality of third cells connected to each other, a pressure sensor, and a controller. The controller measures first time during when a pressure in the first cell changes from a third pressure to a fourth pressure when implementing a first mode by shifting from a third mode, measures second time during when a pressure in the second cell changes from the third pressure to the fourth pressure when implementing a second mode by shifting from the first mode, measures third time during when a pressure in the third cell changes from the third pressure to the fourth pressure when implementing a third mode by shifting from the second mode, and determines a position of a sacral region of a user based on the first time, the second time, and the third time.

A body state determination device includes a detection unit that is configured to detect a plurality of pressure distributions formed by a body weight of a user, and a determination unit that is configured to determine a state of a body of the user by comparing the plurality of pressure distributions detected by the detection unit with each other.

A fluid mattress is provided with a fluid supply unit, a fluid path, a plurality of first cells connected to each other, a plurality of second cells connected to each other, a plurality of third cells connected to each other, a pressure sensor, and a controller. The controller measures first time during when a pressure in the first cell changes from a third pressure to a fourth pressure when implementing a first mode by shifting from a third mode, measures second time during when a pressure in the second cell changes from the third pressure to the fourth pressure when implementing a second mode by shifting from the first mode, measures third time during when a pressure in the third cell changes from the third pressure to the fourth pressure when implementing a third mode by shifting from the second mode, and determines a position of a sacral region of a user based on the first time, the second time, and the third time.

A bed device includes: an operation section that receives an operation input; a controller that controls a movement of the bed in accordance with the operation input; a detector that detects a position of a patient on the bed; and, a limitation table that stores a limitation area set on the bed in association with a limitation content, wherein when the position of the patient detected by the detector is included in the limitation area, the limitation content is read out from the limitation table so as to control the controller in accordance with the limitation content. With this configuration, it is possible to provide a higher safety bed device which can not only notify the danger based on the bed movement but also limit the movement of the bed in accordance with the status of the patient or the bed device.

A high-performance bed apparatus is provided. The bed apparatus includes a supporting unit that supports a user, and a control unit that controls an operation of the supporting unit, wherein a speed of the operation of the supporting unit in a case where the user manipulates the supporting unit is higher than a speed at which the control unit automatically causes the supporting unit to operate.

A bed apparatus includes: a mattress mounted on a bed body; and, first cells arranged on both left and right sides in a longitudinal direction of the bed body and is configured to change the body position of a patient on the mattress by inflating the first cells alternately. When the first cells on the left and right sides are inflated, and when a difference in pressure between the first cells on the left and right sides has continuously fallen within a decision pressure value range for a decision pressure value continuation time, the body position of the patient is changed, whereas when the difference has not continuously fallen within the pressure value range for the continuation time or when the difference has continuously fallen out of the pressure value range for the continuation time, change of the body position of the patient will not be performed.

A mattress including air cells that are located on both sides of a user, in which the air cells each have a convex shape on a first side surface, and the air cells are arranged so that the convex shapes thereof are respectively located near shoulder blade outer edges of the user.

A bed device includes: an operation section that receives an operation input; a controller that controls a movement of the bed in accordance with the operation input; a detector that detects a position of a patient on the bed; and, a limitation table that stores a limitation area set on the bed in association with a limitation content, wherein when the position of the patient detected by the detector is included in the limitation area, the limitation content is read out from the limitation table so as to control the controller in accordance with the limitation content. With this configuration, it is possible to provide a higher safety bed device which can not only notify the danger based on the bed movement but also limit the movement of the bed in accordance with the status of the patient or the bed device.

A bed system including an acquisition unit and a display, in which the acquisition unit acquires user interface device information from a plurality of user interface devices and the display displays a plurality of images corresponding respectively to the plurality of user interface devices on a single screen based on the user interface device information. One set of the plurality of user interface device information includes state information including at least one of bed state information relating to the state of one bed among a plurality of beds and user state information relating to the state of a user of the one bed among the plurality of beds. One image among the plurality of images includes a state display corresponding to the state information. When the state information is abnormal, the first display displays a warning display on the one image among the plurality of images.

A bed system includes: an imaging device; a bed on which the imaging device is to be installed; and a controller configured to process an image acquired by the imaging device to predict a possibility of overturning of a user, in which, when it is determined that a state of the user is a first state, the controller predicts the possibility of overturning of the user based on a first parameter, when it is determined that the state of the user is a second state, the controller predicts the possibility of overturning of the user based on a second parameter, the first state is a state of the user different from the second state, and the first parameter is different from the second parameter.
