Description

  The present invention refers to a person who needs care when taking a bath, such as a physically handicapped person or an elderly person (hereinafter referred to as a "person who needs care when taking a bath, such as a handicapped person or an elderly person"). Further, the present invention relates to a bathing lifting device used for bathing “a bather requiring care” may be referred to as a “bather”.

  2. Description of the Related Art Conventionally, services that allow caregivers to bathe care recipients have been provided in care facilities. When bathing a care recipient, one of the most difficult tasks for the caregiver is to bring the care recipient into and out of the bathtub. This is because the bathtub stores hot water in the interior and has a side wall of a predetermined height, and the caregiver needs to get over the side wall to bring the care recipient into and out of the bathtub.

  Therefore, in recent years, bathing apparatuses including elevators that raise and lower a care recipient with respect to a bathtub have been provided. The elevator supports a stretcher and a sitting chair. The care recipient is placed on a stretcher or a chair while sitting on the sitting chair. The chair can be moved in and out of the bathtub.

  When bathing care recipients, the caregivers store hot water in the bathtub in advance. Although the temperature of this hot water is controlled by a caregiver, it is conceivable that the temperature of the hot water deviates from a temperature suitable for bathing. And when taking care recipients using an elevator, the caregiver's hand does not touch the hot water directly when putting the care recipient in the bathtub, so the temperature of the hot water is not suitable for bathing. There is a risk of bathing care recipients. Some care recipients may not be able to get out of the bathtub on their own, resulting in the risk of causing burns from hot water to the care recipient or increasing the burden on the heart caused by cold water was there.

  As a bathing device that displays the temperature of hot water in the bathtub, for example, the tank-equipped bathing device of Patent Document 1 is a covering member that covers the upper opening of the bathtub sub-portion, and an operation panel is provided at a position facing the bather's face. Yes. By displaying the temperature of the hot water in the bathtub on the operation panel, the bather and the caregiver can check the temperature of the hot water in the bathtub.

The positioning frame 303 can be inserted into the groove 211 from the front side of the bathtub 2, and the bathing elevator 3 is placed at a predetermined position (appropriate position) with respect to the bathtub 2 by being inserted to the innermost part of the groove 211. Be positioned.

  Two power supply units 31 are installed on the base frame 301 with a rod 305 to be described later interposed therebetween, and are power supply means for supplying power to the elevation drive unit 32, the detection unit 35, and the control unit 36. As the power supply unit 31, a secondary battery (such as a lithium ion battery or a nickel metal hydride battery) that can be attached to and detached from the base frame 301 may be used. The power supply unit 31 may be provided with an outlet that can be connected to a commercial power supply instead of a secondary battery, and power may be supplied to each unit.

  The elevating drive unit 32 includes a hydraulic cylinder 304, a rod 305 that can advance and retreat in the hydraulic cylinder 304, a hydraulic cylinder 304, and a cover member 306 that covers at least a part of the rod 305. The rod 305 is attached to a substantially central portion of the base frame 301, and the height of the lift drive unit 32 can be expanded and contracted by the rod 305 moving forward and backward with respect to the hydraulic cylinder 304.

  The support arm 33 is fixedly attached to the hydraulic cylinder 304 and moves up and down as the lifting drive unit 32 expands and contracts. The support arm 33 is formed in a substantially Z shape in a side view, and is configured so that the support arm 33 does not hit the bathtub 2 when the support arm 33 is lowered.

  The stretcher 34 is fixedly attached to the support arm 33 and moves up and down as the support arm 33 moves up and down. The stretcher 34 includes a backrest part 341, a collar part receiving part 342 attached to the support arm 33, and a leg receiving part 343, and the backrest part 341 can be adjusted to an arbitrary angle with respect to the collar part receiving part 342. The leg receiving part 343 can also be adjusted to an arbitrary angle with respect to the buttocks receiving part 342.

  In this embodiment, as described above, the left part of the stretcher 34 is used as a backrest part in order to insert the positioning frame 303 into the groove part 211 from the front side of the bathtub 2, but depending on the installation environment, it is inserted from the back side of the bathtub 2. Sometimes. In this case, the leg receiving portion 343 is the left portion of the stretcher 34, but can be used as a backrest portion by being inclined at substantially the same angle as the left side wall 21a.

  In the present embodiment, the detection unit 35 includes a temperature detection unit 351, a first position sensor 352, a second position sensor 353, and a time detection unit 354. The temperature detection unit 351 is attached to the lower part of the support arm 33 and is immersed in the hot water in the bathtub 2 when the support arm 33 descends to detect the temperature of the hot water in the bathtub 2. The temperature detector 351 may be attached to a position where the temperature of the hot water in the bathtub 2 can be detected before the stretcher 34 is immersed in the hot water in the bathtub 2 when the stretcher 34 is lowered. For example, it is good also as attaching to the lower part of the collar part receiving part 342. FIG.

  The first position sensor 352 is detection means for detecting whether or not the position of the bathing lifting device 3 is a position where the caregiver is not allowed to lift the stretcher 34. The position where the lift of the stretcher 34 by the caregiver is prohibited is between the insertion position of the positioning frame 303 with respect to the groove 211 and the position where the second position sensor 353 is turned on (details will be described later). During this time, the person requiring care is placed on the stretcher 34 and moves toward the bathtub 2, or the stretcher 34 is not allowed to move up and down because it is moving from the bathtub 2.

  For example, as shown in FIG. 5, the first position sensor 352 is provided so as to protrude laterally at the distal end of one positioning frame 303 of the two positioning frames 303, and in the direction of arrow A about the shaft portion 352a. It consists of a sensor 352b and a groove 211 that can be rotated. When the positioning frame 303 is inserted into the groove 211, the sensor 352b rotates around the shaft 352a when reaching the position where the sensor 352b and the groove 211 come into contact with each other. Thereby, it is detected that the position of the bathing lifting / lowering device 3 is the position where the stretcher 34 is not lifted / lowered.

  In the second position sensor 353, when the first position sensor 352 is in an ON state (a state in which it is detected that the position of the bathing lifting device 3 is the position where the stretcher 34 is not lifted), the bathing lifting device 3 It is a detection means for detecting whether or not the position is an appropriate position with respect to the bathtub 2 (position where the stretcher 34 may be lowered with respect to the bathtub 2). For example, as shown in FIG. 6, the second position sensor 353 is provided on the distal end portion of the positioning frame 303 and on the distal end side of the positioning frame 303 (see FIG. 3) with respect to the first position sensor 352, and is directed upward by a spring 353a. The sensor 353b is biased and the convex portion 353c is provided so as to project from the groove portion 211. When the sensor 353b reaches the position of the convex portion 353c, the sensor 353b slides downward against the spring 353a against the elastic force. Thereby, it is detected that the bathing elevator 3 has reached an appropriate position with respect to the bathtub 2.

  The spring 353a and the sensor 353b may be provided on one positioning frame 303 of the two positioning frames 303 or on both positioning frames 303, but as shown in FIG. By providing, it can detect reliably that both the positioning frames 303 were inserted in the groove part 211 in parallel.

  That is, in the present embodiment, the stretcher 34 can be lifted or lowered when the first position sensor 352 is in an OFF state (that is, the positioning frame 303 is not inserted into the groove portion 211) or the first position sensor is turned on. When the first position sensor is in the ON state and the second position sensor is in the OFF state, the stretcher 34 is not allowed to move up and down. When the spring 353a and the sensor 353b are provided on both of the two positioning frames 303, the first position sensor is in the ON state and the two second position sensors are in the ON state. When only one of the second position sensors is in the ON state, the elevation is prohibited.

  Although the first sensor 352 and the second sensor 353 have been described as separate members in the present embodiment, they may be realized by the same sensor. For example, as shown in FIG. 7, when the second sensor 353 is used and the positioning frame 303 is inserted into the groove 211, the sensor 353b slides downward against the spring 353a against elastic force against the first recess 353d. The sensor 353b slides further downward against an elastic force against the spring 353a when it moves and further contacts the second recess 353e. Accordingly, the position of the positioning frame 303 with respect to the groove 211 can be detected based on the amount of sliding downward (sliding amount).

  The time measuring unit 354 measures the bathing time of the bather. The measurement start timing and the end timing of the bathing time are not particularly limited. For example, the measurement start timing is determined when the bathing lifting device 3 reaches an appropriate position with respect to the bathtub 2 or in the state. This is when the descent of 34 is completed. The measurement end timing is when the raising of the stretcher 34 is completed or when the bathing lifting device 3 is not in an appropriate position with respect to the bathtub 2. Further, the caregiver may start or end the measurement at an arbitrary timing with respect to one or both of the measurement start timing and the end timing.

  The control part 36 is a control means for controlling the bathing elevator 3 as a whole. In this embodiment, the stretcher 34 is moved up and down by controlling the lift drive unit 32 based on an instruction from the outside. Further, control of information displayed on the display unit 37 is performed. As a display mode on the display unit 37, the control unit 36 displays a first display mode for displaying the temperature of hot water in the bathtub 2 based on the detection result of the temperature detection unit 351, and an elapsed time since the bather started bathing ( The second display mode for displaying the bathing time of the bather is displayed in a switchable manner (FIG. 1 shows the state displayed in the first display mode). In addition, it is good also as having a display mode which displays both the temperature of the hot water in the bathtub 2, and the elapsed time after a bather starts bathing.

  When the display unit is small and it is difficult to display both the temperature of hot water in the bathtub 2 and the bathing time of the bather, a plurality of pieces of information can be confirmed sequentially by displaying each switchable.

  The bathing time of the bather is measured by the time measuring unit 354. When bathing a large number of care recipients at a nursing facility, etc., it is often done by setting the bathing time per person, and by displaying the bathing time, it becomes possible to efficiently bathe the caregivers sequentially. .

  The display part 37 is installed in the upper front part of the cover member 306, and it is easy for a caregiver to check while bathing a care recipient.

  The present invention can be used for an elevating device for bathing.
