Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed apparatus which can be used in various states, and more particularly to a bed apparatus applied to a nursing bed.

[0002]

2. Description of the Related Art In beds used in hospitals and other medical institutions, even if a bedridden patient or a patient who can move, the type of rug and the installation state in accordance with the degree and type of the disease. The sleeping comfort is greatly changed by changing.

[0003] Especially for bedridden persons, it is desirable to change the sleeping state so that bedsores do not occur. In addition, it is desired from a nursing work point that it is possible to easily shift from a bed to a bathtub even when taking a bath.

[0004]

Although expensive multifunctional beds are available on the market, they are not widely used because of the problems of installation scale and installation profitability. on the other hand,
A general bet has an extremely simple structure in which a rug is simply placed on the horizontal frame portion of a bet frame formed by a pipe, and the rug is quickly placed according to the situation of a sleeping person. You can't change or swap things out, and if you try to do it little, the burden of that task will be substantial.

[0005] Furthermore, the work of taking a patient into a bath is quite difficult for the attending nurse, and it is a difficult task to move the patient from the bed to the bathtub while holding the patient. You can say that. Therefore, there are devices that use a device such as a small crane to lift and move the patient, but the device is expensive and has not yet been widely used. In addition, there is also a problem that lifting up as described above gives a patient anxiety.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the various problems in the prior art, and to improve the sleeping comfort by easily changing the installation state and type of the rug even when the user is sleeping. Another object of the present invention is to provide a bed apparatus which can be used for bathing, and which can simplify the bathing of the bed user, is practical and advantageous in cost as a whole, and is particularly effective for nursing.

[0007]

SUMMARY OF THE INVENTION The present invention for solving the above-mentioned problems comprises a lower frame and an upper frame which are connected to each other so as to be vertically movable, and is provided inside the lower frame and the upper frame. A bet body having a waterproof structure having a space in which a rug is detachably housed, and a plurality of shafts connected to each other so as to be vertically movable, and provided at a corner of the bet body so as to extend vertically. A plurality of combined shafts, a tire body provided at a lower portion of each of the combined shafts so as to be able to enter and exit the bet body, and a corner portion supported at an upper portion of each of the combined shafts; It is characterized by comprising a mesh body arranged so as to cover the whole, and driving means for driving the combined shaft body into and out of the bed body.

By changing the height of the upper and lower frames of the bed body appropriately to set the height, the state of the main bed body is changed according to the situation of the sleeping person or the rugs used. When changing rugs, workers can easily change rugs, regardless of the person sleeping, by extending the combined shaft and raising the whole net while sleeping. It can be carried out. Similarly, when taking a bath, raise the whole net while keeping it in a sleeping state, remove the rug, and raise the upper and lower frames so that the space of the waterproof bed body can be used as a bathtub. If the net is lowered after the hot water is put in the section, it is possible to take a bath while sleeping. Further, the bet body can be smoothly and easily moved to an arbitrary place by the installed tire body.

[0009] Further, by connecting to the bottom of the outer side of the bed main body with a vertically rotatable and vertically movable lifting / lowering means, the bed main body can be changed to an arbitrary direction and height. Etc. can be improved.

[0010] Further, by providing a handle for tensioning or loosening the net, the net can be tensioned or loosened as necessary in accordance with the situation of a sleeping person. Work that does not cause anxiety to the sleeping person becomes possible.

When the bed body 1 is used as a bathtub, the net 38 is raised together with the sleeping person as shown in FIG. As shown in FIG. 13 (b), the rugs are taken out, and if necessary, a sheet body 39 shown in FIG. 12 is laid in the space 4, and the lower frame 2 and the upper frame 3 are separated from each other to obtain a space having an appropriate capacity. Part (bathtub) 4 and then lower the upper vertical pipe 26a or rotate the handle 51 provided with a reverse rotation preventing means such as a ratchet mechanism to loosen the net 38 from the tension state. The net 38 is lowered to an appropriate position in the bathtub. And pre-wash if necessary,
The dirt is discharged from the drain pipe 43. Then, by putting hot water into the bathtub, it is possible to take a bath with the hot water in the net 38.

After taking a bath, the net 38 is raised together with the bather who has wiped his / her body, and after the hot water is drained from the drainage pipe 43, the space 4 is cleaned, and the rugs are set in the space 4 again. After that, the net 38 is returned to the original position, and the bather is returned to the predetermined position. At the time of bathing, the bed body 1 can be easily moved to an appropriate room or the like, and the surroundings of the bed body 1 may be covered with a curtain.

[0025]

As described above, according to the present invention, by setting the height by appropriately raising and lowering the upper and lower frames of the bed body, it is possible to match the situation of the sleeping person or the rugs used. The state of the main bed body can be changed, and by extending the combined shaft body while raising the net and raising the net together, the operator can easily change the rug regardless of the sleeping person. Can be done. Similarly, when taking a bath, you can go up with the net while you are sleeping, remove the rug, and raise the upper and lower frames to use the waterproof bed body as a bathtub. By lowering the whole net after putting it in,
It is possible to provide a bed apparatus that is practical and effective in nursing work, such as being able to take a bath while sleeping.
