Detailed Description

The controller key box 1 is manufactured by injection molding through a plastic mold, the sliding tube 7 is manufactured by a metal tube or a plastic tube matched with the linear bearings 6-1 and 6-2, the metal sliding rod 5 is manufactured by electroplating a metal rod matched with the sliding rod, and the inverted U-shaped part is manufactured by bending a metal sheet shear plate to manufacture other parts which are commercially available. The prepared parts can be used after being assembled according to the specification and attached drawings. Before use, the patient is in a recumbent state, and the controller key box 1 is positioned at a position from the middle part of the guardrail 4 to the side of the head of the guardrail 4, namely, a position near the forearm of the patient in the recumbent state. When a patient wants to sit up, a back lifting key is pressed down, a back bed plate 12 of the electric nursing bed is lifted, as the tail end of the sliding tube 7 is provided with a small hole 8-1 with the diameter of 2-3mm, a rope 10 in a rope fixed pulley groove is wound with a rope 10 in two pulley grooves of a V-shaped groove fixed pulley 9 at the tail end of a metal sliding rod 5, the tail end of an extension arm 13 of the back bed plate 12 of the nursing bed is pulled, when the back bed plate 12 is lifted up, the back bed plate 12 rotates forwards to lift up, the bed plate is driven to generate a reaction force on the extension arm 13 by taking a rotating shaft as a center, namely a backward acting force, and the traction force of the tail end pulling rope 10 drives the sliding tube 7 to drive a controller key box 1 fixed by adhesive to move forwards and in the bed tail direction. Meanwhile, since the end of the rope 10 at the head side of the controller key case 1 is connected with a tension spring/rubber strip 14 having a tensile length of 500mm and a tensile force of 0.5Kg and the end thereof is fixed to the nursing bed bottom frame 15 under the head side of the guard rail 4, the tension spring/rubber strip 14 is elongated and generates elastic potential energy during the horizontal movement of the controller key case 1 along the metal sliding rod 5 toward the tail direction. When the back bed board 12 rises to the limit position of about 75 degrees, the back lifting electric push rod is contacted with the inner limit switch, and the automatic power-off operation is stopped. At this point the controller key box 1 has stopped near the patient's forearm on the bed tail side of the guardrail 4. When a patient wants to lie down, the back descending key of the controller key box 1 is pressed, the gear motor of the electric push rod runs reversely, and the back bed board 12 descends, so that in the process that the controller key box 1 horizontally moves along the metal sliding rod 5 towards the tail direction, the elastic potential energy generated by the stretching of the tension spring/rubber strip 14 is released and converted into kinetic energy to pull the rope 10 with the small hole 8 at the head side end of the sliding tube 7 so that the sliding tube 7 drives the controller key box 1 to move along the metal sliding rod 5 towards the head side direction, and when the back bed board 12 returns to the horizontal position, the controller key box 1 also returns to the initial position, namely, the position where the key is convenient to operate by the patient by hands. In another embodiment of the invention, when a patient wants to sit up, a 'back lifting' key of the controller key box 1 arranged on the middle sheet head side of the guardrail 4 and positioned on the initial position nut pipe 18 is pressed, the power supply of the miniature speed reduction motor M connected in parallel with the back lifting electric push rod is automatically connected, the metal long screw 16 hinged with the speed reduction motor M runs forward while the back bed plate 12 is lifted, the nut pipe 18 and the controller key box 1 connected through the inverted U-shaped part 3 are driven to move towards the direction of the bed tail, as the power supply of the electric push rod is connected in parallel with the power supply of the miniature speed reduction motor M, when the patient sits down from the flat position to the 75 DEG angle limit position of the back bed plate 12, the limit switch arranged in the electric push rod is touched, the electric push rod motor and the miniature speed reduction motor M are automatically powered off simultaneously, and the controller key box 1 is automatically moved to the position close to the position of the guardrail 4 by the patient's self operation by the self through the inverted U-shaped part 3, and the controller key box 1 is automatically moved to the position close to the position of the bed tail of the guardrail 4 when the patient wants to operate by self, and the back lifting electric push rod is conveniently moved to the position close to the position of the patient's position of the miniature speed reduction motor M when the patient sits down from the flat position to the position of the patient. When a nursing staff operates, the inverted U-shaped part connected with the controller key box 1 can be taken down, the controller key box 1 is hung on the sliding tube 7 or the nut tube 18 in an outward manner, and when the illness state of a patient is improved and the patient operates by himself, the controller key box 1 is hung inwards. The invention adopts the lifting of the back bed board 12 as power, namely a sliding tube-fixed pulley mode or a miniature gear motor M as power to drive a long screw rod-nut tube/gear engaged rack-sliding tube mode, and the controller key box 1 can automatically move along with the change of the patient body position when the patient sits up, lies down or semi-lying down, and the controller key box 1 always tracks the position nearby the hand operation position of the patient, so that the function of self-operating nursing bed of the patient is convenient, and the self-care capability of the patient is improved.
