Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a bed particularly suitable for preventing bedsores. When pressure is applied to the area, blood circulation in the area is obstructed, which can lead to ulcers and ulcers, commonly referred to as ``bedsores,'' which cause great pain to the patient.

It is more likely to occur in people with poor nutritional status who are severely weakened by severe pressure sores, people with paralysis or swelling, and people who are incontinent.In addition, if the sleeping position is supine, the sacral region, shoulder blades, back of the head, Pressure is placed on bony areas such as the greater trochanter, ankle, elbow, and acromion on the lower side when lying on the side, such as on the outside of the heel-elbow joint, making bedsores more likely to occur.

It is said that it is a shame for nurses to create bedsores on patients, and the reality is that the prevention of bedsores is left solely to the care of nurses. This means lifting the patient's body and changing its position from time to time. Instead of lying completely on your side or supine, place a comfort post between your body and the bed to slightly shift your center of gravity. Careful attention is required to keep the skin clean and strengthen the skin's resistance by repeatedly wiping the back and pine surges.

[Problem that the invention seeks to solve]

Therefore, the reality is that caring for bedridden patients is an extremely burdensome task.

As mentioned above, the most important reason for bedsores is that a specific part of the body is under pressure for a long period of time, and this will not go away unless the body position is changed. When a patient is unable to move his or her body, the only option is to move the patient's body artificially or mechanically, or conversely to change the position of the patient by moving the bed that supports the patient. However, it is difficult in practice to mechanically change the position of a sick person, as a nurse would do with a sick person.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a bed that prevents bedsores by mechanically changing the posture of the bed body that supports the patient's body.

[Means for solving problems]

The present invention provides a bed body, a support mechanism that rotatably supports the bed body around an axis set above the center parallel to the surface of the bed body, and a support mechanism that supports the bed body continuously or intermittently in place of the axis. The bed is characterized by being equipped with a drive mechanism that changes the posture in the circumferential direction by displacing the bed.

[Effect]

By changing the posture of the bed itself, the position that supports the patient's body while lying on the bed changes, thereby avoiding a situation where a particular area is continuously under pressure for a long time.

〔Example〕

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

In FIGS. 1 and 2, guide rollers 2, 2 are installed on a pair of left and right foot stands 1, 1, and a bed main body 3, which has a curved surface with a constant radius on its outer surface, is straddled over both guide rollers 2, 2. be installed. In the case of the embodiment, a semi-cylindrical body is used for the bed body 3,
The case is shown in which an elastic body 4 is attached to the inner surface and a cushion 5 is further installed inside the elastic body 4.

As a drive mechanism for this bed body 3, there is a
Round cam 7 having continuous right-handed and left-handed threaded grooves 6
The pin 9 of the driven body 8, which is provided with a piece (not shown) that engages with the groove 6, is engaged in the elongated hole 11 of the bar 10, which is suspended with its upper end fixed to the bed body 3. A reciprocating mechanism is used. A motor 12 with a built-in transmission is directly connected to the circular cam 7, and the circular cam 7 is driven by the motor 12.
When the bar 10 is rotated in one direction, the bar 10 reciprocates along the axis of the circular mound cam 7, and the bed body 3 connected to the upper end of the bar 10 moves back and forth along the axis of the circular mound cam 7.
is guided by the guide rollers 2, 2, and makes a reciprocating angular movement from side to side with its arc center 0 as the rotation axis.

The important point in the present invention is that the bed body 3 is angularly displaced using the axis set at the upper center as the rotation axis to control its posture, and the drive mechanism thereof is not limited to the above-mentioned mechanism. . A mechanical, electric or hydraulic mechanism is used, and if necessary, a brake is provided to give angular movement to the bed body 3 so that it can be stopped in any angular position.

In the embodiment, a first
Patient M is placed in a supine position as shown in the figure.

At this time, the center of the arc of the bed body 30 is the frontal part of the human body,
It is particularly desirable to locate it between the eyeballs.

In this state, the motor 12 is started to angularly displace the bed body 3 at a low speed of about 2 degrees of rotation per minute. As a result, the weight of the human body always acts downward, but since the angle of the bed body 30 that supports the human body is angularly displaced in the left and right circumferential directions, the part of the human body that receives pressure from the bed body 3 changes every moment.
Situations in which a specific area is under continuous pressure for a long time can be avoided. However, the bed main body 3f is not limited to continuous driving, but can be converted into any angular posture by intermittent driving. The posture change of the bed body 3 is performed by the nurse or the patient himself using a hand switch.
Alternatively, it is controlled by a computer programmed with conditions such as angular velocity, stopping angle, and angular displacement range.

〔Effect of the invention〕

As described above, according to the present invention, since the bed body is angularly displaced in the circumferential direction with the axis set above the bed body as the rotation center to change its posture, the area where the patient's weight acts on the bed body It is therefore possible to eliminate or reduce "bedsores" caused by prolonged pressure on a specific part of the body. Furthermore, since the present invention angularly displaces the bed body around its central upper axis, the patient is not shaken greatly during the posture change operation of the bed body, and therefore a comfortable bed can be provided.

Therefore, according to the present invention, it is possible to relieve the patient from the pain of bedsores and to reduce the burden on the nurse.
