Description

Technical Field

[0001] The invention relates to the technical field of medical education equipment, in particular to a device for automatically moving an electric nursing bed controller for convenient operation by patients. Background Art

[0002] Domestic and foreign enterprises that develop and produce electric medical care beds are developing rapidly. There are many types of electric medical care beds. In order to realize the functions of electric care beds, controller buttons and control handles that can be operated by patients are basically set on the guardrails. However, if the fixed controller is set on the guardrail, it is difficult to operate after the patient sits up because the patient's hand is too far away from the controller. Therefore, some companies have also added fixed controllers on the left and right sides of the guardrails near the end of the bed for the patient to operate when sitting up, and also set a controller button box facing outward for nursing staff to operate, but the controller cost is significantly increased. If an LCD touch screen controller is used, the cost is even higher; if a control handle button is used for operation, the text / logo of the button is 2 times smaller than that of the fixed controller, and patients with poor eyesight are difficult to operate. Moreover, after the patient sits up or lies down, the patient is very easy to forget (even normal people often can't find their mobile phones), which is not very convenient to use. Therefore, a device that automatically moves the electric care bed controller is developed to facilitate patient operation. Summary of the invention

[0003] The purpose of the present invention is to develop a device for automatically moving the controller of an electric nursing bed for easy operation by the patient. The patient operates the controller when lying or sitting. After changing to a sitting or lying position, the controller automatically moves to a position convenient for the patient to operate. Since it is convenient for the patient to operate by himself, it is beneficial to improve the patient's self-care ability.

[0004] The present invention solves the problem that it is inconvenient for patients to operate and control the electric nursing bed by themselves, and fills the gap of a device in the medical device field for automatically moving the electric nursing bed controller to facilitate patient operation.

[0012] Figure 5 A schematic diagram of a controller key box sliding device according to another embodiment of the present invention DETAILED DESCRIPTION

[0014] The controller button box 1 is made by injection molding of a plastic mold, the sliding tube 7 is made of a metal tube or a plastic tube matching the linear bearings 6-1 and 6-2, the metal sliding rod 5 is made by electroplating a metal rod matching the sliding rod, and the inverted U-shaped component is made by bending a metal sheet. Other parts are available on the market. Prepare various parts and assemble them according to the instructions and the drawings in the instructions. After debugging, they can be used. Before use, the patient is in a supine position, and the controller button box 1 is located in the middle of the guardrail 4 to the head side of the guardrail 4, that is, near the forearm of the patient in a supine state. When the patient wants to sit up, he presses the "back raising" button, and the "back bed board" 12 of the electric nursing bed rises. Since a small hole 8-1 with a diameter of 2-3 mm is set at the tail end of the sliding tube 7, the rope 10 in the fixed pulley groove is wound around the rope 10 in the two pulley grooves of the V-groove fixed pulley 9 set at the tail end of the metal sliding rod 5, and pulls the end of the extension arm 13 of the back bed board 12 of the nursing bed. When the back bed board 12 rises, the power of the back bed board 12 rotating forward drives the bed board to generate a reaction force on the extension arm 13 with the rotating shaft as the center, that is, a backward force, and the traction force of the rope 10 at its end causes the sliding tube 7 to drive the controller button box 1 fixed to the inverted U-shaped component 3 with adhesive to move forward and to the end of the bed. At the same time, since the end of the rope 10 on the bedside of the controller button box 1 is connected to the tension spring / rubber strip 14 with a stretch length of 500mm and a tension of 0.5Kg; its end is fixed on the bottom frame 15 of the nursing bed below the head side of the guardrail 4, the tension spring / rubber strip 14 is stretched during the horizontal movement of the controller button box 1 along the metal sliding rod 5 toward the end of the bed, generating elastic potential energy. When the back bed board 12 rises to the limit position of about 75°, it touches the inner limit switch of the back rising electric push rod, and automatically cuts off the power and stops running. At this time, the controller button box 1 has stopped near the patient's forearm on the bedside side of the guardrail 4. When the patient wants to lie down, he presses the "back down" button of the controller button box 1, and the reduction motor of the electric push rod runs in the reverse direction, and the back bed board 12 descends. Therefore, in the process of horizontal movement of the controller button box 1 along the metal sliding rod 5 toward the end of the bed, the elastic potential energy generated by the elongation of the tension spring / rubber strip 14 is released, and converted into kinetic energy to pull the rope 10 fixed by the small hole 8 at the head side end of the sliding tube 7, so that the sliding tube 7 drives the controller button box 1 to move along the metal sliding rod 5 toward the head side. When the back bed board 12 returns to the supine position, the controller button box 1 also returns to the initial position at the same time, that is, the position where the patient can operate the buttons conveniently with his hands.In another embodiment of the present invention, when the patient wants to sit up, he presses the "back raising" button of the controller button box 1 on the nut tube 18 at the initial position on the middle head side of the guardrail 4, and the power supply of the micro reduction motor M connected in parallel with the back lifting electric push rod is automatically turned on. When the back bed board 12 rises, the metal long wire rod 16 hinged to the reduction motor M runs forward, driving the nut tube 18 and the controller button box 1 connected by the inverted U-shaped component 3 to move toward the end of the bed. Since the power supply of the electric push rod is connected in parallel with the power supply of the micro reduction motor M, the back bed board 12 rises from the horizontal position to the 75° angle limit position when the patient is in a sitting state, touching The electric push rod has a built-in limit switch, and the electric push rod motor and the micro-reduction motor M are automatically powered off at the same time. Since the controller button box 1 is hung on the nut tube 18 / sliding tube 7 through the inverted "U-shaped" component 3, the controller button box 1 automatically moves to the side of the guardrail 4 at the end of the bed, which is convenient for the patient to operate the button by himself; when the patient wants to lie down, he presses the "back down" button, and the reduction motor and micro-reduction motor M of the back lifting electric push rod both run in the opposite direction, the electric push rod retracts, and when the back bed board drops to the limit position of 0°, that is, the horizontal position, the controller button box 1 has moved from the side of the bed of the guardrail 4 to the initial position of the guardrail, which is convenient for the patient to operate the button by himself. When the nursing staff operates, they can remove the inverted U-shaped component connected to the controller button box 1, hang the controller button box 1 outward on the sliding tube 7 or the nut tube 18, and when the patient's condition improves and operates by himself, hang the controller button box 1 inward. Whether the present invention adopts the lifting and lowering of the back bed board 12 as the power, that is, the sliding tube-fixed pulley method, or adopts the micro-reduction motor M as the power to drive the long screw-nut tube / gear meshing rack-sliding tube method, the controller button box 1 can automatically move with the change of the patient's body position when the patient is sitting up, lying down or in a semi-recumbent position. The controller button box 1 always tracks near the position convenient for the patient's hand operation. Since it is convenient for the patient to operate the functions of the nursing bed by himself, it is beneficial to improve the patient's self-care ability.
