Description

[Detailed description of the invention] [Field of industrial application] This invention is a medical device in which the divided floorboards consisting of the back bottom, waist bottom and foot bottom arranged on the floorboard frame can be raised and lowered freely, and can be operated by gears. The present invention relates to medical beds, and particularly to medical beds that facilitate diaper changes for patients on the bed.

[Conventional technology]

Beds that can be operated by gears are generally known as medical beds.

As an example of this, for example, one in which divided floorboards are arranged on a floorboard frame is known. Although not shown, this includes a floor plate frame and a floor plate arranged on the floor plate frame and consisting of a back bottom, a waist bottom, and a foot bottom, and the back bottom is rotatable in the direction of the waist bottom or foot bottom. One side is fixed on the frame, and each of the waist bottom and foot bottom is arranged so as to be rotatable in the direction of the back bottom, and one side is fixed on the frame to make the patient's posture on the bed comfortable. By undulating the back bottom, waist bottom, or leg bottom, so-called gear operation becomes possible.

[Means for solving ideas]

For bedridden elderly patients, seriously ill patients, and other patients who require diapers, the caregiver must lift the patient from the side of the bed when changing diapers on the bed, which requires a lot of effort. This can be difficult and can cause back pain for caregivers.

It is also possible to use a device to lift the patient, such as a lift, but it can be time-consuming to use, and if used incorrectly, it can cause fractures of bones in the patient.

Therefore, the purpose of the present invention is to add a diaper changing function to a bed with a gear mechanism, thereby making it easier to change diapers on the bed in addition to the aforementioned gear operation, and to provide a medical bed that solves the drawbacks of the known beds mentioned above. The aim is to provide a bed for people to use.

[Means for solving problems]

In order to achieve the above-mentioned objective, according to the present invention,
It includes a floor plate frame, and a floor plate arranged on the floor plate frame and consisting of a back bottom, a waist bottom, and a foot bottom, respectively, and the back bottom is rotatable in the direction of the waist bottom or the foot bottom, and has one side on the frame. In a medical bed that can be operated by gears, each of the waist bottom and the leg bottom is rotatable in the direction of the back bottom and is arranged with one side fixed on the frame. a first shaft installed in the horizontal direction, a second shaft installed in the horizontal direction on the floorboard frame below the waist bottom, a first link with one end fixed to the first shaft, and a first link with one end fixed to the first shaft; a telescoping rod rotatably connected to the free end of the first link, the other end being fixed to the floor plate frame; and an actuator having one end rotatably connected to the free end of the first link a rod; a second ink having one end fixed to the second shaft and the other end rotatably connected to the free end of the operating rod; one end fixed to the second shaft and the other end; and a support rod to which a roller is rotatably attached, and the roller is located below the waist bottom at a position that creates a gap between the roller and the waist bottom before operation. .

Hereinafter, the present invention will be explained in detail using the accompanying drawings.

1 and 2 are perspective views of essential parts of a specific example of the bed of the present invention, in which FIG. 1 shows the state before operation, FIG. 2 shows the state after operation, and FIG. 3 shows the state shown in FIGS. 1 and 2. A partially enlarged cross-sectional view of FIG. 2 is shown, and FIG. 4 is an explanatory diagram showing the state of the patient and bed during diaper changing.

In FIG. 1, reference numeral 1 denotes a rectangular floorboard frame, and a floorboard 2 is placed on top of this floorboard frame 1. As shown in FIG. The floorboard 2 consists of a back bottom 3, a waist bottom 4, and a foot bottom 5. Among these, the back bottom 3 is attached with one side 3a on the floorboard frame 1 by a pin 6 in the direction of the waist bottom 4 or foot bottom 5 ( The waist bottoms 4 and foot bottoms 5 are arranged so as to be rotatable in the direction of the arrow).
It is fixed on the top by pins 7 and 8 so as to be rotatable in the direction of the back bottom 3 (in the direction of the arrow). In addition, an outer waist bottom 9 is further provided on the outside of the waist bottom 4, and diaper changing operations are performed using the waist bottom 4 as described below.
The outer bottom 9 is in charge of gear operation.
It is also possible to perform both operations on separate bottoms.

Further, a first shaft 10 is horizontally installed and fixed on the foot bottom 5, and a second shaft 11 is horizontally installed on the floor plate frame 1 below the waist bottom 4 between the opposing side frames 1a and 1b. will be erected and fixed.

12 is a first link, 13 is a second link,
14 is a telescopic rod, 15 is an operating rod, and the first link 12 has one end 12a connected to the first shaft 1.
One end 13a of the second link 13 is fixed to the second shaft 11, and one end 14a of the rod 14 is rotatably attached to the free end 12b of the first link 12 by a pin 16. Along with being connected,
The other end 14b is fixed to the floor plate frame 1 by a pin 17, and one end 15a of the operating rod 15 is rotatably connected to the free end 12b of the first link 12 by a pin 16, and the other end 15a is rotatably connected to the free end 12b of the first link 12 by a pin 16. The end 15b is rotatably connected to the free end 13b of the second link 13 by a pin 18. The rod rod 14 is configured by screwing the other end 14b into the outer cylinder 19.
Crank handle 12 attached to the end of 9
By the rotational operation, a thread (not shown) is applied between the rod rod 14 and the inner side of the outer cylinder 19, and the length of the rod rod 14 is adjusted in a telescopic manner by this screw action.

21 is a support rod, one end 21a of which is fixed to the second shaft 11, and the other end 21b of which a roller 22 is rotatably attached. Furthermore, this roller 22 is attached to the waist bottom 4 as shown clearly in FIG.
It is arranged at a position below the waist bottom 4, and at a position where a gap 23 is created between the waist bottom 4 and the waist bottom 4 before operation.

[Effect]

In the bed of the present invention constructed as described above, when the crank handle 20 is rotated to shorten the rod 14 from the length shown in Fig. 1 to the length shown in Fig. 2, the free end 12b of the first link 12 is pulled in the direction of the arrow as shown in Fig. 2, and at this time, the first link 12 rises and the foot bottom 5 rises due to the rising of the first link 12. At the same time, the operating rod 15 is also pulled in the direction of the arrow, and at this time, the second link 1
As the leg bottom 5 rises, the support rod 21 also rises due to the rotation of the second shaft 11, and the roller 22 attached to the other end 21b of the support rod 21 comes into contact with the hip bottom 4 as shown in Figs. 2 and 3, pushing it up and causing the hip bottom 4 to stand up. At this time, since there is a gap 23 between the hip bottom 4 and the roller 22, the rise angle of the hip bottom 4 is 1/100th of that of the leg bottom 5.
Therefore, as shown in FIG. 4, the feet of a patient 24 on a bed are supported high by the foot bottom 5, and the hips are lifted by the hip bottom which stands at a small angle, making it easy to change diapers.

It goes without saying that the bed of the present invention, in addition to the above-mentioned diaper changing operation function, also has a gear function by appropriately undulating the back bottom 3, outer waist bottom 9, and leg bottom 5, although not shown in the drawings.

[Effects of the invention] As described above, the bed of the present invention has a diaper changing function added to the bed that has a gear function.
In addition to gear operation, it is also easy to change diapers on the bed, making it especially suitable for bedridden elderly people, critically ill patients, and other patients who require diapers.
