And, each button selection It consists of a confirmation button 119 for selecting and inputting the user confirmation.

The signal distributor 130 is provided on the side rail of the bed and the patient control board 120 for detecting a button selected by the patient, and the angle of generating an electrical signal when the angle of the backrest, legrest, tilt of the bed A sensor unit 134 to 136 and a scale unit 140 for receiving a signal detected from four load cells 141 to 144 provided to measure the weight of the patient, and measuring the weight of the patient; The bed angle control signal and the bed height control signal of the patient control board 120 or the bed angle control signal and the bed height control signal of the main control board 100 are selected and transmitted to the motor controller 150 to adjust the bed angle. And, the bed angle data detected through the angle sensor unit (134 ~ 136) is output to the main control board 100, the weight data of the patient input from the balance unit 140, the main control It consists of a signal splitter 130 for output to a load (100).

Here, the angle sensor unit 134 ~ 136 is composed of a backrest angle sensor 134, a legrest angle sensor 135 and an inclination angle sensor 136.

The detailed operation of the present invention configured as described above will be described in more detail with reference to FIGS. 1 to 5 as follows.

First, the present invention is fixed to the frame of the bed of the medical bed, the legrest, the tilt angle and the total tilt angle and the height of the bed of each motor and the angle sensor for detecting each angle is fixed, by controlling each motor The patient control board with buttons is provided on the side rail of the bed so that the patient can directly adjust the angle and the bed height of the bed, and the main control board is provided on the top of the foot panel for easy adjustment by the nurse or guardian.

That is, by using the patient patient control board and the nurse main control board provided in the bed is provided so that the patient or nurse can conveniently operate according to the condition or needs of the patient.

As shown in FIG. 3, the operation switch unit 110 for adjusting a backrest, a legrest, a bed height, and a bedside depression by operating a button according to a patient's state or need as shown in the front display of the nurse main control board. Each of the up (△) or down (▽) button (113 ~ 116) of the () is controlled.

In addition, the initialization button (CPR) 111 is to perform the initialization of the back of the needle, the backrest, the overall height to the default position set at the same time. That is, while pressing the reset button 111, the backrest, the legrest, the total inclination and the bed height are controlled at the same time to return each motor to the initial setting position.

The control button 112 is a patient control board control button for selecting the operation lock or release operation of the patient control board 120 in a locked state to prevent the patient from operating arbitrarily using the patient control board 120 Do this.

The backrest control button 113 is composed of a pair of up and down control buttons (△, ▽), and when the button is pressed to operate the main controller 102 detects the motor controller (130) through the signal distributor (130) It is delivered to the 150 to drive the third motor 153 by the motor controller 150, the backrest is raised and lowered.

In this case, when the signal distributor 130 measures the inclination angle of the backrest by the first angle sensor 134 and outputs it to the main controller 102, the main controller 102 converts the input angle signal into a number. The backrest angle will be displayed.

The footrest control button 114 also comprises a pair of up and down control buttons (△, ▽), and when the button is pressed to operate the main controller 102 to detect the signal distributor 130 The motor controller 150 is transmitted through the motor controller 150, and the motor controller 150 drives the fourth motor 154 to raise and lower the legrest.

At this time, the signal splitter 130 measures the angle of the footrest to the second angle sensor 135 and outputs it to the main controller 102, the main controller 102 converts the input angle signal to a number The angle of the legrest is displayed on the liquid crystal display 103.

The bed height adjustment button 115 is composed of a pair of adjustment buttons (△, ▽) for raising, lowering the height of the bed, and the nurse or guardian by pressing it detects the main controller 102 The motor controller 150 is output to the motor controller 150 through the signal splitter 130, and the motor controller 150 drives the first and second motors 151 and 152 to move up and down.

The inclination adjustment button 116 is composed of a pair of buttons (△, ▽) for adjusting the overall inclination of the bed in the forward, reverse direction, the signal is detected by the main controller 102 when pressing the corresponding button The controller 130 is transferred to the motor controller 150 through the distributor 130, and the motor controller 150 drives the first and second motors 151 and 152 in different directions to set the inclination of the needle in the forward or reverse direction. To adjust.

In this case, when the signal distributor 130 measures the inclination angle of the bed on the third angle sensor 136 and outputs it to the main controller 102, the main controller 102 converts the input angle signal into a number. The inclination angle of the needle is displayed on the liquid crystal display 103.

As such, the head, food and needle angles are simultaneously displayed on the liquid crystal display 103 as shown in FIG. You can check with.

 The scale button 117a is a button for measuring and checking the weight of the patient. When the nurse or the guardian selects this, the scale button 117a switches to the weight measurement mode and the signal distributor 130 has four load cells 141 to the bottom of the bed. 144 receives the weight data from the balance unit 140 and outputs it to the main controller 102, the main controller 102 receives it and displays it on the liquid crystal display 103.

At this time, the main controller 102 reads the initial weight of the patient measured and stored in the built-in memory, and calculates a change amount by subtracting the current weight from the initial weight of the patient.

As illustrated in FIG. 5, the liquid crystal display 103 sequentially displays the patient's first weight, the changed weight, and the current weight, thereby showing the patient's weight change state at a glance. Make sure to check.

On the other hand, when the menu button (118) is pressed while the current measured weight is displayed in the scale mode, a message "Do you want save first?" Is displayed through the liquid crystal display 103. Press Enter (119) to save the currently measured weight as the initial weight.

The zero button 117b is a selection button for setting the currently measured weight in the scale mode by the scale button 117a to a '0' point. When the zero button 117b is selected in the scale mode, “0” is selected. Do you want zero? Message is displayed on the liquid crystal display 103, and when the user selects the enter button 119, the current weight is set to zero, and the liquid crystal display 103 ), The current weight (Now) is displayed "00.0Kg".

What has been described above is just one embodiment for implementing a medical bed control device using a control board, the present invention is not limited to the above embodiment. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
