Description

[Detailed description of the invention] [Industrial Application Field J The present invention relates to a bed for treating bedsores and the like.

``Conventional technology j Conventionally, a rubber cone (doughnut-shaped) has been used to treat mild bedsores in the lumbosacral and greater trochanteric regions, but because it surrounds the bedsore in a circle, it is not breathable. This can lead to poor blood circulation, so it is necessary to change positions frequently.

Therefore, a method was devised in which the body was supported parallel to the pillar by folding a long blanket or rolling it into a cylindrical shape, but this required effort when changing positions and caused serious problems such as cerebral hemorrhage, bedridden elderly people, and people with general weakness. The patient had no effect and bedsores occurred all over the body (head, auricles, both shoulders, both elbows, back, lumbosacral region, greater trochanteric region, both thighs, both knees, both lower knees, both ankle joints, both heels). 1 foot section and 1 foot section on both evenings).

Therefore, bedsore prevention mats are used, but these mats are air mats made of rubber fabric in the form of rafts (parallel cylinders), and the air pressure is 1 to 1.
It is a compressed air device that can be adjusted in 8 stages, and it is a mat-L
A small amount of air is discharged from a large number of pores on the surface, and adjacent cylinders alternately supply and exhaust air (air injection, degassing) at regular intervals. However, when you lie on your back on such a mat, the mat becomes flat due to your weight, and the area that comes into close contact with your body is large to support your body. More than half of the area will be in close contact with the mat during air injection.

The mat at the boundary between the air injection part and the deaeration part overlaps, and that part is always in close contact with the mat. In addition, the adhesion area changes due to differences in body weight, and the resting area of the back (the area other than the adhesion agent) is variable, so there are individual differences, and it is difficult to match the effects of promoting blood circulation, preventing bedsores, and treating the effects of pine surge. Ta.

``Problems to be Solved by the Invention'' The present invention attempts to treat bedsores of critically ill patients without requiring any human intervention, regardless of the patient's weight difference.

"Means for Solving the Problems" The present invention provides a bed floor in which fixed parallel rigid body members and movable elevating parallel rigid body members are alternately arranged on the upper part of the machine frame, in which the upper surface level of the movable parallel rigid body members is The treatment bed is supported to be movable up and down above and below the level of the upper surface of a fixed parallel rigid rod, and is provided with a lifting device for driving the movable parallel rigid rod.

``Operation'' Therefore, when a thin mattress is spread on the bed floor, the patient is placed supine on it, and the elevating drive device is started, the movable parallel rigid rod slowly rises and stops, and then slowly descends again.
- It stops when the surface level matches the upper surface level of the fixed parallel rigid rod. After that, it further slowly descends and stops, then rises again and stops when the upper surface level matches the -F plane level of the fixed parallel rigid rod, and the same operation as described above is repeated. When the movable parallel rigid rod rises from the state where the upper surfaces are aligned, the patient is slightly lifted by the rod and is supported by the movable parallel M1 rod, creating a gap in the middle of the rod. Therefore, the pressure on the skin and muscles is released, the body becomes in a closed position, and air permeability is promoted. After that, when the movable parallel rigid rod descends and its upper surface becomes below the level of the upper surface of the fixed parallel rigid rod, the patient will be supported by the fixed parallel rigid rod, and the two body parts will be supported and compressed and move. The compression part by the parallel rigid rods is released and becomes the body state. By repeating the above alternating compressions, blood circulation is promoted, muscles and skin are massaged, and breathability is promoted.

``Example'' Eight parallel rods 2 made of wooden logs are arranged on the top of the machine frame 1, and both ends are fixed to the machine frame 1 (FIGS. 3 and 4).

The diameter of the log is 5 cm, and the distance between the sides is 7 cm.

A diameter of 5 cm is placed in the above-mentioned space between parallel rods 2.2 and 2.2.
A movable parallel rod 3 made of a wooden log of The lower end of the upper steel rod 9 is slidably supported on a horizontal guide 10 provided at the lower part of the machine frame 1, and the lower end of the upper steel rod 9 is pivotally supported at the lower part of the machine frame 1 by a pin 8. The upper end of the upward steel rod 9 is slidably supported on the horizontal guide guide 10 provided on the lower surface of the elevator frame 6, and the lower part of the machine frame 1 is supported by a pin 12. The middle of the pivoted upward arm 13 and the lower part of the machine frame 1 are connected by a cylinder 14, and the upper end of the upward arm 13 is slidably connected to the lower part of the lifting frame 6 by the expansion and contraction of the cylinder 14. The movable parallel rigid rod 3 can be raised and lowered via the lifting frame 6 by raising and lowering the upward arm 13, and constitutes a lifting drive device 5. The movable parallel rod 3 is raised and lowered slowly or gradually by the slow expansion and contraction of the cylinder 14, and it rises from the solid line position in FIGS. 1 and 2 to the imaginary line position 1.
It can be lowered to the original solid line position and comes to a standstill at the upper and lower limit positions and at the same level of the upper surface level of both rigid rods 2.3.One resting time can be freely set from 5 minutes to 1 hour, and the ascent and descent are gradually carried out. It will be held in In Figure 4, the movable parallel rod 3 is divided into two at the center, and the divided rods are raised and lowered at different times, and the divided movable parallel rods 3.3 are arranged alternately in a staggered manner as shown in Figure 5. Also good. Further, the above-mentioned dividing position may be determined as appropriate, and the movable parallel rod 3 can be formed to be detachable, and at one dividing position, a divided space is created, which is good for ventilation. Further, the M-body rod 2.3 may be a metal rod whose outer surface is covered with a rubber plate or a sponge plate. 15 in the figure is a fixing arm of the fixed parallel rigid rod 2, 16 is a support stand of the machine frame 1, 17 is a wheel provided on the support stand 16, 18 is a pivot pin for raising and lowering the machine frame 1, 19 2 is a hoisting handle of the machine frame 1, 20 is a hoisting screw, 21 is a hoisting arm, and 22I''i is a female screw for hoisting of the same arm 21.

``Effects'' Since the present invention is configured as described above, it improves the ventilation of the affected area, automatically performs muscle and skin pine surge, and constantly eliminates tight contact areas and eliminates blood circulation disorders, improving blood circulation and ventilation. By the simultaneous progression of pressure ulcers, bedsores can be treated without the need for human intervention.
