Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a medical bed.

(Prior art and its problems) Examples of conventional medical beds used by patients include those shown in FIGS. 3a, b, and c.
With such a conventional medical bed a, as shown in FIG. If you are trying to move to another place, first raise your body by yourself or with the help of a caregiver, or by raising the floorboard on your back, as shown in Figure b, and then turn to the side of bed a. As shown in Figure c, the robot takes a sitting position on the edge of the bed a, then stands up and walks, thereby moving to the desired location. Conversely, in order for patient B, who has been away from bed A, to lie down on bed A, he must first place his hips on the edge of bed A, as shown in Figure c. Lower it, then change the direction of your body, and
By assuming this posture and then leaning back the upper body, one can lie down on bed a as shown in figure a.

In this way, in the conventional medical bed a, patient b on bed a may move away from bed a, or conversely, patient b who was away from bed a may
When patient B returns to bed A, there are many complicated movements such as changing the direction of the body one by one.Moreover, without the help of a caregiver, patient B must move his body on his own, which reduces the burden on patient B. For patient b, such as an elderly person with a large body and particularly weak arm strength, it is difficult to move from bed a. Further, even if the caregiver helps, the caregiver must support the weight of patient b, and even in this case there is a problem in that the burden on the caregiver is large.

The present invention aims to solve these problems.

(Means for solving the problems) The configuration of the present invention is shown in FIGS. 1 to 2 corresponding to embodiments.
To explain based on the drawings, first, the medical bed 1 according to claim 1 has a bed base 2 divided in the lateral direction at a position corresponding to the knee, and an above-knee base 2a.
and a below-knee base 2b, the below-knee base 2b is configured to be movable by casters 3 and detachable from the above-knee base 2a, and the floor plate 4 on the above-knee base 2a is designed to accommodate the waist. The back floor plate 4a and the waist floor plate 4b are divided in the transverse direction at the positions, and the back floor plate 4a is configured to be rotatable around the pivot point 5 on the waist floor plate 4b side. , has a structure that can be tilted with the head side facing upward, and furthermore, the rotation means 6 of the back side floor plate 4a and the back side floor plate 4a,
A fixing means 7 for fixing the knee in an inclined state with the head side facing upward is provided at an appropriate location on the above-knee base body 2a.

Further, in the bed described in Item 1, the rotating means 6 and the fixing means 7 are connected to the lower side of the back floor plate 4a and the above-knee base 2a at appropriate positions, for example, with the member 8. In between, attach the operating rod 9 side to the back floor plate 4.
A gas spring 10 connected as the a side and the gas spring 10 provided on the side of the back floor plate 4a.
It is composed of an operating lever 11.

(Actions and Examples) Next, the operation of the present invention will be explained along with examples.

As shown in FIG. 1a, the below-knee base body 2b is configured to be detachable from the above-knee base body 2a via a connecting portion 13. As shown in FIG. The connecting portion 13 is connected to the lower knee base 2, as shown in the embodiments of FIGS. 2a, b, and c, for example.
A rotation fulcrum 15 is provided at the tip of a support arm 14 protruding from a suitable position on one side corresponding to the above-knee base 2a side of b.
A hook 16 configured to be rotatable around this rotation fulcrum 15, and a below-knee base 2b of the above-knee base 2a.
An operating rod 18 is connected to the hook 16. If the connecting portion 13 is configured in this way, the hook 16 can be easily hooked onto the engaging rod 17 as shown in FIG. It can be brought into the state shown in FIG. 2b when it is removed from the engagement rod 17. Therefore, the lower knee base 2b can be placed in relation to the upper knee base 2a.
It can be configured to be detachable.

When the patient 12 is normally on the medical bed of the present invention, as shown in FIG.
is connected to the above-knee base body 2a via the connecting portion 13, and can thus be used as a normal bed. When the patient 12 on the bed 1 in such a state leaves the bed 1, for example, as shown in FIG. Let go. Since the below-knee base 2b is configured to be movable by the casters 3, it is extremely easy to move the below-knee base 2b. In this way, the lower knee base 2
b away from the above-knee base 2a, the patient 12 can bend his knees and thus put his feet on the floor. Of course, the height of the floorboard 4 is adjusted in advance so that when the patient 12 puts his/her feet down in this manner, the patient's 12 feet can reach the floor sufficiently.

Next, the rotation means 6 is driven to rotate the back side floor plate 4a.
When the patient 12 is gently rotated upward around the rotation fulcrum 5, the upper body of the patient 12 gradually rises, and the patient 12 can finally take a posture of sitting on the lumbar floor plate 4b. Once the patient 12 has taken this position, the fixing means 7 is driven to fix the back floor plate 4a so that it does not return to its original position.

In this way, the patient 12 is able to sit on the lumbar floorboard 4b with the help of the rotational movement of the backside floorboard 4a, making it easier for the patient 12 to sit on the floorboard 4b. Since you are already on the floor, all you have to do is stand up and start walking, and you can easily move to your desired destination.

If the patient 12 who has left the bed 1 in this manner returns to the bed 1 and rests there, the procedure described above may be reversed. That is, the patient 12 first assumes a posture of sitting on the lumbar floorboard 4b, and then leans on the backside floorboard 4a, which is already fixed in an inclined state, and rests the upper body on this. After that, the fixing means 7 of the back side floor plate 4b is released, and the rotating means 6 is moved to the back side floor plate 4b.
A is driven in the direction to return to the original flat state, and the back side floorboard 4b is slowly brought down to return to the flat state. Next, the below-knee base 2b is brought closer to the above-knee base 2a, and the patient's 12 foot is placed on the below-knee base 2b.
When the connecting portion 13 is finally connected, the patient 12 can lie down and rest on the bed 1 as before.

In the embodiment shown in FIGS. 1a and 1b, the back side floor plate 4a
For example, the rotating means 6 and the fixing means 7 of
This is a tilting mechanism for the floor plate 4 using the gas spring 10 described in Publication No. 38989, and the operating lever 1
1, the back side floor plate 4a can be easily rotated and fixed at a desired inclination angle.
Further, it goes without saying that the rotating means 6 and the fixing means 7 may be constructed of an electric motor and a screw shaft that is rotated and expanded and contracted by the electric motor.

(Effects of the Invention) As described above, the medical bed of the present invention allows a patient to stand up from a sitting position without changing the direction of the patient's body when getting on and off the bed. In addition, since the patient can lie down on the bed from a sitting position, the effort borne by the patient or his/her caregiver when getting on and off the bed can be significantly reduced.
