BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the bed apparatus according to the present invention will be described in more detail with reference to the drawings. The term “before and after” as used herein means that the patient is lying on his / her back on the bed apparatus, and the patient's head side is the front and the foot side is the rear. As with the left and right, the right hand side of the patient is the right and the left hand side is the left.

Further, in the bed apparatus of the present invention, the rod-like body group forming the floor describes and describes only the type of mechanism that moves adjacently in the front-rear direction and moves in the front-rear direction. Needless to say, it also includes, for example, the type of mechanism that moves adjacently in the left-right direction and moves in the left-right direction.

As shown in FIG. 1 and FIG. 2, the floor portion of the bed apparatus 1 is composed of a bottom member 3 that is a rod-like body, and the bottom member 3 is separated by a connecting member 4. It is connected in parallel and below the horizontal position so that it cannot bend but can be bent upward, and is connected to the bottom end rollers 5 and 5 as an example at the end of the upper part of the frame via arms 5a and 5a. .

[0017] As shown in Figs. 1, 2, and 7, the bed apparatus 1 includes a side frame 6 and a gas frame in addition to the floor portion. Id frame 7, head frame (not shown), frame consisting of foot frame (not shown), shelf 11, exchange lifting and holding means 12, mechanical transmission (movement) moving means 13, power unit 14, power It consists of a link 16, a tip lifting arm 20, a front bottom intermediate lifting arm 25, a rear end lifting arm 30, and a rear bottom intermediate lifting arm 35. The mechanical transmission moving means 13 is composed of a hollow shaft motor 13a, a chain sprocket 13b, and a chain 13c wound around the chain sprocket 13b! RU

[0018] The bottom end rollers 5 and 5 shown in FIG. 2 are freely rotatable with respect to the bottom end opening fixed shafts 5b and 5b penetrating the central axis in the left-right direction. 5b is supported by rails 6a and 6a on the side frame 6. The bottom end rollers 5, 5 are moved in the front-rear direction by moving the bottom end roller fixing shafts 5 b, 5 b by mechanical transmission means such as a chain of the mobile movement means 13 or a screw shaft.

In the invention according to Patent Document 1, as shown in FIGS. 2 and 3, the pinions 24 and 24 are attached to the left and right ends of the bottom end roller fixing shafts 5b and 5b, The pion 24, 24 was rotated manually or with a motor roller to move the fixed shafts 5b, 5b. For this reason, it is necessary to move the electric power and control system wires as they are wired near the fixed shafts 5b and 5b. However, the movement of the wires is not required by the mechanical transmission mechanism of the machine movement means 13. Therefore, it has been greatly improved in terms of safety, maintenance and cost.

[0020] It should be noted that the mobile movement means 13 allows the floor portion of the bed apparatus 1 and the bottom end rollers 5, 5 to be independently moved and adjusted in the front-rear direction, and independently moved and moved. By making it adjustable, the opening 51 of any size between the bottom end rollers 5 and 5 can be quickly opened and closed as needed. In addition, a programmable control function is also provided. By setting in advance, the size, movement speed, movement range and number of movements of the above-mentioned opening 51 are automatically manipulated to prevent and rehabilitate critically ill patients. Appropriate combination of sensors can be used to automate the changing of diapers and positioning when using toilets, improving the ease of nursing care.

Next, based on FIGS. 4 to 6, the driving force of the operating mechanism of the bottom front end lifting arm 20, the bottom rear end lifting arm 30, the front bottom middle lifting arm 25, and the rear bottom middle lifting arm 35 is described. An example in which a link is used for transmission of data will be described. In the example shown in the figure, the tip lifting arm 20 and the rear lifting arm 30 constitute the end lifting means in claim 2. 3a is a floor portion end portion facing the front end portion 5, and 3b is a floor portion end portion facing the rear end portion 5. The positions of the floor portion end portions 3a and 3b are end positions. Varies according to the lifting / lowering operation of the unit lifting / lowering means. Reference numeral 3c denotes an intermediate portion between the front end portion 5 and the floor portion end portion 3a. The front inclined guide 50 and the front bottom intermediate lifting arm 25 constitute a floor portion intermediate lifting means. 4 to 6 are cross-sectional views of the bed device 1 having a left-right symmetric structure, as viewed from the right side. FIG. 4 shows a state in which the power unit 14 is not operated, and therefore the power unit arm 15 and the power link 16 are not both operated, and shows the state of each arm when the floor portion is flat. Each rotary shaft provided at the tip of each arm, that is, bottom tip lift arm rotation shaft 20a, bottom rear end lift arm rotation shaft 30a, front bottom middle lift arm rotation shaft 25a, rear bottom middle lift arm rotation shaft 35a Are on the same horizontal plane, and the floor members laid around each rotating shaft have the same height.

A horizontal floor is formed, which is suitable for normal supine and used for the basic position of prone position. The power unit arm 15 rotates about a shaft 15a, and the power link 16 is supported so as to be movable in the front-rear direction with respect to the frame.

FIG. 5 shows an example of changing the floor shape by operating the power unit 14 in a state where only the links and the arm 'rotating shafts are extracted. In the figure, the support shaft 20b, the support shaft 25b, the bottom rear end raising / lowering arm shaft 30b, and the support shaft 50b are fulcrums provided rotatably on the frame. When the power unit 14 is actuated, the power unit arm 15 rotates clockwise, and when the power link 16 moves forward, the connecting portion 20c also moves forward, and the bottom end lifting arm 20 uses the support shaft 20b as a fulcrum. Stands upward in a clockwise direction. At the same time, the front guide link 60 also moves forward together with the rear connection portion 60b by moving the front connection portion 60c forward, and the front inclined guide 50 having the support shaft 50b is rotated clockwise with the support shaft 50b as a fulcrum. Raise upward, thereby raising the front bottom intermediate lifting arm 25 in the upper position upward in the same clockwise direction using the support shaft 25b as a fulcrum.

[0023] Here, there is a space before the operation between the upper roller 50a provided at the tip of the front inclined guide 50 and the front bottom intermediate lifting arm 25 (see Fig. 4). roller 50a does not come into contact with the front bottom intermediate lifting arm 25 immediately after the operation, and the front bottom intermediate lifting arm 25 starts to rise with a time lag after the forward inclined guide 50 is raised to a certain height, so that the floor portion It has a two-step slope, and this shape forms an optimal floor for critically ill patients in upper-up prone position. Also, by adjusting the time difference, it is possible to accommodate and adapt to individual differences such as the height of the patient, and by adjusting the length of the front bottom intermediate lifting arm 25, the back holding the pillow can be raised You can also.

Next, the operation mechanism of the bottom rear end lifting arm 30 will be described with reference to FIG. The bottom rear end ascending / descending arm 30 lowers the lower leg exclusively, and is a force that lowers the floor level and lowers the rear end, mainly for some patients with severe physical condition etc. The bottom end rollers 5 and 5 are preliminarily moved to the local area of critically ill patients and are provided with an opening 51 that matches the size of the toilet. Prepare a toilet (not shown) placed on (not shown) and raise it to an appropriate height. At this time, in order to accurately align the toilet bowl locally, the bottom end rollers 5 and 5 can be quickly and accurately set by the mobile moving means 13 in the front-rear direction. Just do it.

[0025] It is to be noted that the power unit 14 is operated to rotate the power unit arm 15 clockwise, the power link 16 is moved forward, the connecting portion 20c is also moved forward, and the bottom end lifting arm 20 is supported by the support shaft. It rises clockwise with 20b as a fulcrum, but the long hole connecting part 16s provided at the rear end of the power link 16 has a certain frictional resistance in the long hole part, but it slides with more force In this way, the connecting portion 30c of the bottom rear end raising / lowering arm 30 is connected, and after the tip raising / lowering arm 20 is in a certain erection state, the lower leg lowering state is synchronized and lowered clockwise. It is safe, easy, and easy to excrete using a toilet without moving critically ill patients.

[0026] In addition, there are many cases in which relatively mild patients are desired to operate and use toilets by themselves, but this need can be met.

[0027] Next, the operation mechanism of the rear bottom intermediate lifting arm 35 will be described. After turning off the connection of the unnecessary connection part, the front connection part 60c of the front guide link and the connection part 30c of the bottom rear end lifting arm, the power unit 14 is operated and synchronized with the bottom end lifting arm 20 After bottom By raising and lowering the intermediate lifting arm 35, the force that can be used as a standard for reclining the back-raised 'knee-up' is used. The rear bottom intermediate lifting arm 35 is separated from the power link 16, and the original 'dedicated drive device (not shown) ), And can be applied to rehabilitation functions such as contracture prevention / improvement of the lower limbs depending on the combination of the operation mechanism and the operation of the bottom end roller 5, and the function can be further enhanced.

[0028] FIG. 7 is a diagram for explaining the replacement product lifting and holding means 12. As an example, both ends are provided at the rear end of the floor portion formed by the rod-shaped body group 3 and the both end rollers 5, 5. After moving the rollers 5 and 5, the appropriate opening 51 is provided, and the expansion and contraction band 12 a of the replacement lifting and holding means 12 provided in the rear frame of the bed apparatus 1 is attached to the both end rollers 5 and 5. Be prepared to turn it back through between the 5 appropriate openings 51. A shelf 11 that can be pulled out is provided in front of the floor portion, and a device such as an air-nosed (air-type portable bathtub) 18 that has been evacuated is placed on the shelf 11 as specified, and the rear end of the air bath 18 Is held by the gripping part 12b at the tip of the stretchable belt 12a, the stretchable belt 12a is lifted and the end of the airbus 13 is lifted and held to a predetermined position on the bottom, both end rollers 5, 5 Is moved to the front end of the floor part while maintaining the appropriate opening 51, so that the existing rug is sequentially lowered onto the shelf 11 so as to peel off the foot end force from between the appropriate openings 51, and at the same time the air nose 18 is Foot force can be lifted to the floor so that it is applied sequentially, and the existing rug and air bath 18 can be safely and easily exchanged from the bottom of the body without any movement of critically ill patients, and can be used for bathing.

[0029] FIG. 8 is a view for explaining the invention of claim 4. A sheet material 70, which is formed in a cylindrical shape and has an inner surface side that is excellent in slipperiness and an outer surface side that is non-slipper, is formed on the top of the bottom. In the example of the bed apparatus 1 used in the above, the sheet material 70 is placed in the cylinder with the front bottom end roller 5 placed in the cylinder, and then moves up and down to move forward on the front bottom. At the rolling axis 20a, the bottom member descends downward along the outer periphery of the front end of the bottom member, and moves backward under the bottom member on the guide frame 7 to raise the outer periphery of the rear end of the bottom member on the guide frame 7 It is mounted with the arm rotating shaft 30a moving forward on the bottom and with the rear bottom end roller 5 placed in the cylinder.

[0030] Since the sheet material 70 is cylindrical and the inner surface is slidable, it easily tunes to the bottom movement 'shape and always covers the bottom surface. Texture A feeling can be obtained, and the mechanical image of the bed apparatus 1 with high functions can be wiped off. In addition, when a roller is selected for the bottom member 3 ..., the rug changing system work becomes smoother, and the rug may be shifted backward when raising the upper half of the seat. By using, the exchange system is smooth, but there is also an effect that it is difficult for deviation to occur.

Next, another embodiment of the invention described in claim 4 will be described with reference to FIG. The sheet material is a single material whose back surface is slidable.The front floor sheet material 80a at the upper part of the front floor part from the bottom end lifting arm rotating shaft 20a of the bed apparatus 1 to the front bottom terminal part, and the rear There is a rear floor sheet material 80b in the upper part of the rear floor part from the bottom end part of the bottom to the bottom rear end lifting arm rotating shaft 30a part, both of which fix one of the bottom front and rear end parts or the bottom front and rear end parts Connect the other side to the unloading machine.

[0032] In Fig. 9, the front end of the front floor sheet material 80a having a predetermined length is connected to the front scraper 81a which is attached to the front frame of the bed and wound around a predetermined amount by a predetermined amount, and the rear end is connected to the front bottom end roller. Connect to the fixture 82a at the front of one. In addition, the front end of the rear floor sheet material 80b having a predetermined length is connected to the fixing member 82b immediately after the rear bottom end roller, and the rear end is attached to the rear frame of the bed. Connect by winding a predetermined amount. This has the same effect as the sheet material 70 described above. Furthermore, the required rigidity strength of the bottom can be reduced by means of strengthening the punching force of the punching machines 81a and 81b to a certain level or temporarily locking the punching.
