Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a bed for patients who are bedridden, elderly, or disabled.

(Prior art) Conventionally, when bathing a bedridden patient, multiple nurses had to pick up the patient, lower them into the bathtub, give them a bath, then pick them up again and carry them to the bed. This not only placed a heavy burden on nurses, but also caused safety issues.

(Problem to be solved by the invention) This invention was made in view of the above-mentioned conventional circumstances, and its first purpose is to treat a sick person lying in bed, requiring multiple nurses. To provide a bed for a patient that can be safely transported between the bed and a bathtub without any problems.

A second object of the present invention is to prevent the mechanical part for transporting the sick person from getting in the way when the bed is used for a mildly sick person.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the patient's bed of the present invention has a head part and a foot part provided in a box shape at the side ends of the base frame so as to be slidable in the horizontal direction. A guide wheel is provided at one end of the lower surface of the head portion and the foot portion to be grounded on a guide rail provided on the base frame, and an auxiliary leg with wheels is provided at the other end to be grounded to the floor surface. A lifting bar for a patient's lifting mat is removably installed between the sections, a rotating mechanism for the lifting bar is removably built into the head or foot, and leg rods for placing the bathtub are provided on the side of the bed body. It is characterized by having been provided.

(Function) According to the above means, the bathtub is positioned adjacent to the bed body using the leg levers for placing the bathtub, and the patient placed on the lifting mat is lifted onto the bed by sliding the head and foot sections. The patient is horizontally transferred from the main body to the upper part of the bathtub, and then the lifting mat is lowered by operating the lifting device, and the patient is lowered into the bathtub and taken a bath. After bathing, the patient is returned to the bed body by raising the lifting mat and sliding the head and foot parts. At this time, the head and foot close the front and rear open sides of the lifting mat and support the patient's load on the lifting mat, while the guide wheels guide the sliding of the head and foot and work together with the auxiliary legs. Prevents cantilever support of the head and foot parts. At the same time, the lifting bar and its rotation mechanism are removed from the bed main body so that the bed main body can also be used for mildly ill patients.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The bed body A has a base frame _A4 surrounding a bed _A3 which _{is rectangular} in plane, and _a mat _A5 . slidably connected to.

As shown in Fig. 3, the base frame _a4 has a square pipe shape with a hollow interior, but on the short side where the bed part _a1 and foot part _a2 are connected, the base frame a4 has almost the entire length in the longitudinal direction. A guide elongated hole 1 is drilled across it, and a guide rail 2 with an L-shaped side surface is formed to extend.

The head part _a1 and the foot part _a2 include a box body 3 with a hollow interior and an open back surface, and the box body 3.
Lid plate ₄ that can be opened and closed on the back via screw A 4
It is formed with the same width as the inner width of the guide rail 2, and the base frame is
A locking pin 5 that locks into the guide elongated hole 1 is protruded from the sliding contact surface with a ₄ , and a locking recess 7 into which the transmission gear 6 meshes is continuously carved on the lower surface.

The transmission gear 6 is provided at both ends of a transmission shaft 6' that is rotatably supported under the base frame _a4 , and is configured to rotate by rotation of a crank-shaped operating lever 2 so that the upper half protrudes from the hole 2'.

Then, the locking pin 5 is locked in the guide elongated hole 1, and the head part _a1 and foot part _a2 are attached to the base frame.
a ₄ in a spliced manner, and the latching recess 5 is meshed with the transmission gear 6. In this way, the operating lever
By this rotation, the head part _a1 and the foot part _a2 are automatically guided by the locking pin 5, and can be slid horizontally and guided to the top of the bathtub C placed adjacently.
Reference numeral 8 is a guide wheel for smooth design, and 9 is an auxiliary leg with wheels that prevents the head part _A1 and foot part _A2 from becoming cantilevered when sliding.
Make it move on top. Note that this auxiliary leg 9 may be moved via a rail 10 laid on the floor surface d.

Further, the head part _a1 and the foot part _a2 are provided with a lifting device B for lifting a patient's lifting mat _b1 .

Lifting device B consists of lifting bar _b2 and its lifting bar.
It consists of a rotating mechanism _b3 that rotates the lifting mat _b2 to raise and lower the lifting mat _b1 .

As shown in FIG. 3, the lifting bar _b2 has a size that allows it to hang between the recessed portions ₁₁ , 11 formed from above on both sides of the opposing surfaces 13, 13 of the head portion a1 and foot portion _a2 . It is a rod material having a length of , with both ends open, and the end portion of the lifting mat _b1 is attached to it, and a receiving member 12 having internal teeth is installed at one end.

The recessed portions 11, 11 allow the lifting bar _b4 to be detachably installed from above.
A through hole 11a communicating with the inside of the box body 3 is formed in one of the inner surfaces of the boxes 1 and 11, respectively.

The rotation mechanism _b4 is built into a hollow case body 14 having a size that allows it to be detachably built into the box body 3, and is formed by a gear train 15 and a chain 17. It consists of a rotating sprocket 16 and is housed in the box body 3.

As shown in the figure, the gear train 15 includes a first gear 19 that can be operated from the outside with an operating lever 18 or the like, and a third gear that meshes with the first gear 19 via a second gear 20 and rotates in opposite directions. and fourth gears 21 and 22, respectively, and support shafts 19', 20', 21', and 2
It is pivoted at 2' and placed inside the case body 14.

The sprocket 16 has the third and fourth gears 21 and 22.
A first sprocket 16 is provided coaxially with the first sprocket 16, and a second sprocket 16 is linked to the first sprocket 16 via a chain 17. In addition, when the case body 14 is assembled into the box body 3, the second sprocket 16 has a support shaft 16' that is connected to the through hole 1.
It is made long so as to protrude from 1a, and a transmission means such as a spline that engages with the receiving member 12 at one end of the lifting bar _b2 is formed on the protruding shaft portion. Reference numeral 23 is a leg rod for placing the bathtub, and one end is pivoted to the side or bottom of the bed _A3 so that it can be taken in and out.

Then, the case body 14 is fitted into the box body 3 so that the spline engages with the receiving member 12 of the lifting bar ^b3 , and it is covered with the cover plate 4, and the first gear 19 is rotated by the operation lever 18. The lifting bars b ₂ and b ₂ are rotated to automatically raise and lower a bedridden elderly person or a disabled person. Thereafter, the head part _a1 and the foot part _a2 are moved in the horizontal direction and transferred into the bathtub C placed on the leg rod 23 for bathing (see FIGS. 7 to 9).

In addition, this bed with lifting device B is shown in Fig. 10,
As shown in FIG. 11, after opening the cover plate 4, removing the internal rotating mechanism _b3 and removing the lifting bar _b2 from the recessed part 11 restores the bed to a normal bed ( (See Figure 12).

(Effects of the invention) Since the invention is constructed as described above, it has the effects described below.

The bathtub is placed adjacent to the bed body using the leg rods for placing the bathtub, the patient lifting mat is supported by the horizontally sliding head section and the foot section, and the head section and the foot section are supported by the guide wheels and auxiliary legs. The foot can now slide more reliably and safely, making it extremely easy to bathe a bedridden patient without requiring multiple nurses, and at the same time improving safety when transporting the patient. It can also provide an excellent bed for patients.

Furthermore, by making the lifting mat, the lifting bar, and its rotating mechanism detachable, it can be used for patients ranging from mildly sick patients to severely bedridden patients.
