Description

Bed with wheelchair}

The present invention relates to a bed used by a patient with impaired mobility, and more specifically, to a bed equipped with a wheelchair that is normally used for resting and sleeping, but when necessary, the wheelchair can be separated from one side and used to transport the patient.

A wheelchair is a four-wheeled chair designed to enable patients who have difficulty walking on their own or who require stability to move while sitting.

The method of placing a bedridden patient in a wheelchair is to first place the patient on the bed, then bring the wheelchair closer to the bed, and then have the patient get out of the bed on his or her own (or with the help of a guardian). ), the wheelchair should be approached to the rear of the patient while the patient is standing and centered on the floor, and the patient should be seated.

Likewise, although the wheelchair is a device originally manufactured to assist patients who have difficulty standing on their own or who have difficulty walking, the patient must stand on his own or with the help of a guardian, and when he is in bed, he must get out of the bed and touch the floor. There is an unreasonable point in having to bear the inconvenience of having to maintain your balance and stand up.

The same problem occurs when transferring from a wheelchair to a bed.

Moreover, in the case of seriously ill patients, such as patients with paraplegia or general weakness, it is impossible for them to stand on their own, so at least two or more guardians must completely lift the patient and place him or her in a wheelchair, which requires a lot of strength for both the patient and the guardian. , Many fall accidents occur during this process, so improvement is urgently needed.

When a patient wants to climb onto the bed while riding the wheelchair 200, first place the wheelchair 200 in the space between the bed units 100 and then place the wheelchair 200 on the bed. Manipulate the provided controller to raise the lifting cushion (250).

The lifting member 270 raises the lifting cushion 250 to the set height, and when the lifting cushion 250 rises to the same height as the top of the bed unit 100, the operation of the lifting member 270 is automatically stopped. .

When the lifting cushion 250 is raised, the first fixing pin 242 of the first locking member 240a is pulled out from the first through hole 241 to release the locking state of the backrest main body 230.

Then, the backrest main body 230 is rotated rearward.

When the backrest portion 230 is rotated rearward, the support frame 232 provided at the lower portion of the backrest main body 231 rotates toward the elevating cushion 250 in the opposite direction to the backrest main body 231, and the backrest portion 230 When it rotates horizontally and becomes fully flat, the support frame 232 is supported on the lower part of the lifting cushion 250.

In this way, the backrest 230 in a state in which the support frame 232 is supported on the lower part of the lifting cushion 250 is no longer allowed to rotate backward, and the patient's force acting on the backrest 230 is no longer allowed. Weight is supported stably.

In addition, when the backrest 230 is in a fully flat state, the horizontal connecting bar 300 supports the lower part of the backrest main body 231, thereby greatly improving the support of the backrest 230 and simultaneously moving the wheelchair 200 backwards. will not be pushed aside.

In this state, the pair of bed parts 100, the backrest part 230 of the wheelchair 200, and the lifting cushion 250 all form the same horizontal plane, forming an overall integrated bed shape.

Therefore, the patient can naturally lie down leaning against the backrest 230 in a very safe state, and in this state, by simply lifting the legs and turning them to the side, the head and legs are moved to one side of the bed 100 and the other side of the bed 100, respectively. ), so you can lie down in a comfortable position.

In this way, the present invention allows a patient with impaired mobility to easily move from bed to wheelchair 200 or from wheelchair 200 to bed on his own without the need for an assistant.

Meanwhile, when the height of the armrest unit 220 is high, the armrest unit 220 may protrude from the top of the bed unit 100 even if the backrest main body 230 is completely rotated to a full flat state.

Figure 5 is a side view showing another embodiment of the wheelchair constituting the present invention, and Figure 6 is a usage state diagram according to Figure 5. As shown, to prevent the above phenomenon from occurring, the wheelchair 200a is equipped with armrests. A backrest portion 230 hinged to rotate back and forth may be provided at the rear end of the portion 220.

Additionally, a connecting link 221 is connected between the front end of the armrest portion 220 and the seating frame 210.

The connecting link 221 is coupled in a vertical state so as to be able to rotate in the forward and backward directions, and rotates backward along the backrest main body 230 when the backrest main body 230 rotates rearward.

Therefore, when the backrest 230 is completely rotated to a full flat state, the connecting link 221 rotates to a horizontal state and the height of the armrest portion 220 is adjusted downward, and as a result, the armrest portion 220 is adjusted downward to the bed portion 100. ) and does not protrude upward.

In this case, a second locking member 240b is provided at the hinge joint between the connecting link 221 and the seating frame 210 to limit the rotation of the connecting link 221.

The second locking member 240b may be provided with a second through hole 243 formed in the hinge coupling portion of the connecting link 221 and a second fixing pin 244 fitted into the second through hole 243. You can.

Therefore, when the second fixing pins 244 are inserted into each of the second through holes 243, the connection link 221 is not allowed to rotate and is in a locked state, and the second fixing pins 244 are inserted into the second through holes (243). When pulled out from 243), the connection link 221 can be rotated and converted to the unlocked state.

In this embodiment, the second locking member 240b is shown as an example of a second through hole 243 formed in the hinge coupling portion and a second fixing pin 244 inserted into the second through hole 243. However, there is no need to be limited to this, and any locking member that can limit the rotation of the connection link 221 can be applied.

Therefore, when the patient wants to climb on the bed while riding the wheelchair 200a, the wheelchair 200a is first placed in the space between the bed units 100 and the wheelchair 200a. ) to raise the lifting cushion 250.

When the lifting cushion 250 is raised, the first fixing pin 242 of the first locking member 240a is pulled out from the first through hole 241 to release the locking state of the backrest main body 230 and simultaneously lock the second locking member 240a. The second fixing pin 244 of the locking member 242 is pulled out from the second through hole 243 to release the locking state.

Then, the backrest portion 230 is rotated rearward.

When the backrest portion 230 is rotated rearward, the vertical connecting link 221 rotates rearward along the backrest main body 230 that rotates rearward, and in this process, the armrest portion 220 moves backrest main body ( As it moves rearward along 230), the height is adjusted downward by the rotation radius of the connection link 221.

When the backrest body 230 is in a fully flat state, the connecting link 221 is in a horizontal state, and as a result, the armrest portion 220 is in a horizontal state together with the backrest portion 230 and the connecting link 221. The height is adjusted downward and does not protrude to the top of the bed unit 100.

In this state, the pair of bed parts 100, the backrest body 230, the armrest parts 220, and the lifting cushion 250 of the wheelchair 200a all form the same horizontal plane, forming an overall integrated bed shape, so it is easy to use. There is no inconvenience.
