Description

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

Traditionally, when bathing a bedridden patient, it was necessary for multiple nurses 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. Not only did this place a heavy burden on the staff, but it also posed a safety problem.

The present invention was developed in view of these conventional circumstances, and its purpose is to safely transport a sick person lying on a bed between the bed and the bathtub without requiring multiple nurses. The goal is to provide a bed for the sick that can be used.

In order to achieve the above-mentioned object, the patient's bed of the present invention has a hollow box connected to the outside of the head and foot of the bed body so as to be able to slide in the horizontal direction, and one end of the lower surface of the box The device is equipped with a guide wheel that touches the ground on a guide rail provided at the head or foot, and an auxiliary leg with wheels that touches the floor at the other end, and a hoisting device for lifting a patient's hoisting mat between both boxes. It is characterized by having the following.

According to the above method, a bathtub is positioned adjacent to the bed body, and a patient placed on a hoisting mat is
Both box bodies are slid to be horizontally transferred from the bed body to above the bathtub, and then the lifting mat is lowered by operating the lifting device, and the patient is lowered into the bathtub to take 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 that time, the head and foot close the front and rear open sides of the lifting mat and support the load of the patient on the lifting mat,
The guide ring guides the sliding movement of the head and foot, and the auxiliary legs prevent the head and foot from being supported in a cantilevered manner. At the same time, the load of the patient during normal use of the bed is distributed and supported by the bed's base, which consists of the base frame, head, and foot, and the load during transport of the patient is distributed and supported by the lifting mat and box body. do.

Embodiments of the present invention will be described below with reference to the drawings.

The bed body A has a head part on the base frame _a3 .
A ₁ and foot part A ₂ are erected, and the base frame is
A pinerest _A4 is placed on _A3 , and a toilet E is suspended below the base frame _A3 .

In addition, the bed body A has a head part _a1 and a foot part.
A box D is horizontally slidably connected to the outside of a ₂ , and a lifting bar B of a mat b installed on both boxes D and D is attached to one box D in order to rotate the lifting bar B. Alternatively, the transmission mechanism C accommodated in D is detachably provided.

The base frame _a3 has a vertical rod 2 installed between parallel horizontal rods 1 and 1, and is equipped with a mounting plate 3 at both ends of the horizontal rods 1 and 1, and a head portion _a1 and a foot portion a are attached to the mounting plate 3. Install and fix ₂ .

The head part _a1 and the foot part _a2 have a box shape with a hollow interior, and two rows of upper and lower guide rails 4 and 5 are arranged and fixed in parallel on the back surface of the head part a1 and the foot part a2.

The lower guide rails 4 and 5 are box D.
A metal material with a cross-section of 〓 shape is cut and formed with grooves 4' having approximately the same interval as the width of the metal material. The head part is parallel to the
Attach and fix to the back of A ₁ and foot A ₂ .

Reference numeral 6 denotes a hole opened so that the transmission gear 7 protrudes into the guide rail 4.

Box D allows a lifting bar B and a transmission mechanism C for the lifting bar B to be detachably attached, and includes a box body d ₁ with a hollow interior and an open back side;
It consists of a lid plate _d2 whose open end is removably closed via screws, and a connecting recess 8 with which the transmission gear 7 meshes is carved on the lower surface.

The box bodies d ₁ , d ₁ have recessed portions 10 , 10 formed from above on both sides of the opposing surfaces 9 , 9 , and a hooking rail 11 having a cross-sectional shape “shaped” is attached at a position facing the upper guide rail 5 . Fix it.

The recessed parts 10, 10 allow the lifting bar B of the mat b to be detachably installed from above, and the inner and outer bottom surfaces of the recessed parts 10, 10 are connected to the box body d.
A through hole 12 that communicates with the inside of the container 1 is opened.

The lifting bar B is long enough to hang between the recesses 10, 10, and is provided with a gear 13 at one end.

The transmission mechanism C is built into a hollow case body _c1 having a size that can be built into the box body _d1 , and includes a gear train _c2 and a chain _c3.
Sprocket C ₄ and final gear rotated by
c ₅ .

As shown in the figure, the gear train _c2 includes a first gear 15 that can be operated from the outside with an operating lever 14, etc., and a second gear that meshes with the first gear 15 via a second gear 16 and rotates in opposite directions. 3. It consists of fourth gears 17 and 18, which are pivotally supported by support shafts 15', 16', 17' and 18', respectively, and are disposed within the case body _c1 .

Sprocket c ₄ is the third and fourth gears 17 and 18
A first sprocket _c4 is provided coaxially with the first sprocket c4, and a second sprocket _c4 is linked to the first sprocket _c4 via a chain _c3 . Further, the second sprocket c ₄ has a final gear that meshes with the gear 13 of the lifting bar B through the through hole 12 on the support shaft c ₄ ′.
c ₅ shall be established.

Therefore, the recessed portions 1 of the bed main body A facing each other
Hang the lifting bar B across 0 and 10, and lift the lid plate d ₂
By removing it and incorporating the transmission mechanism C, it changes to a bed with a lifting device.

In this elevating device, the operating lever 14 inserted through the hole 19 formed in the cover plate d ₂ is engaged with a rotating recess (not shown) formed in the support shaft 15', and the operating lever 14 is By rotating the lifting bar B through the gear train c ₂ , _the sprocket c ₄ and the final gear c
Rotate in opposite directions to lift the patient during bathing.

This bed with a lifting device can be restored to a normal bed by opening the cover plate _d2 , removing the internal transmission mechanism C, and removing the lifting bar B from the recessed part 10.

The transmission gear 7 is provided at both ends of a transmission shaft 7' rotatably supported under the base frame _a3 , and is operated by the rotation of a crank-shaped operating lever or by a motor X linked to a switch. It is made to rotate on its own axis and is positioned so that the upper half protrudes from a hole 6 formed in the guide rail 4.

The meshing recess 8 is continuously carved on the lower surface of the box _d1 , and is connected to the transmission gear 7 supported on the transmission shaft 7'.
The boxes D and D can be slid in the horizontal direction by meshing with each other.

As a result, the boxes D and D are automatically moved to the guide rails 4 and 5 by the rotation of the operating lever and motor X.
It becomes possible to guide the bathtub E by sliding it horizontally and above the opened and deployed bathtub E. Reference numeral 20 is a guide wheel for smooth movement, and 21 is an auxiliary leg with wheels that prevents the boxes D and D from becoming cantilevered when sliding so that they move on the floor f of the bedroom F. Note that this auxiliary leg 21 may be moved via a rail laid on the floor surface f.

Note that 22 is a leg for the bathtub E.

Since the present invention is configured as described above, it has the effects described below.

The lifting mat for patients is supported by a box body that slides horizontally, and the guide wheels and auxiliary legs enable the head and foot to slide more reliably and safely, making it easy to lift bedridden patients. To provide a bed for a sick person that allows the patient to be bathed very easily without requiring a plurality of nurses, and also has excellent safety when transporting the sick person. At the same time, compared to a case where the head part and the foot part are provided so as to be able to slide in the horizontal direction and the patient's lifting mat is supported by the head part and the foot part, the base frame, the head part and the foot part are This burden can be reduced and its durability can be improved.
