Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating procedure display device for a multi-item measuring device, and relates to a structure for displaying operating procedures for each test item in a pulmonary function measuring device having a seven-item testing function, for example.

In recent years, various measuring devices have the ability to measure multiple types of items with one device.
For example, lung function measurement devices measure vital capacity (VC), forced vital capacity (FVC), maximum tidal volume (MVV), minute ventilation (MV), functional residual capacity (FRC), closing volume (CV), and lung diffusion. Capacity (DLCO)
These measurements can now be performed with a single device. However, the operations and instructions given to the test subject are different for each measurement item, and the operator must refer to the instruction manual in advance to become fully familiar with the device. There is a problem in that it takes a lot of time to complete the process, and there has been a demand for a multi-item measuring device that does not require such familiarization training.

Next, 8 is a display drum, which is formed into an octahedron by, for example, seven display panels 9 according to measurement items and one non-display panel 10 for reset, as shown in FIG. A display 7 of display items 5 for each measurement item is formed on each display panel 9.
As shown in FIG. 5, the display drum 8 is constructed by mounting the display panel 9 and the non-display panel 10 on the outer periphery of octagonal panel mounting plates 11, 12, and 13, respectively. 11,1
A rotary shaft 15 is fixedly fixed through a shaft support hole 14 formed at the center of each of the shafts 2 and 13. . A rotation position detection portion, for example, a slit 16, is formed in the panel mounting plate 11 at one end. The rotating shaft 15 of the display drum 8 is rotatably mounted on both end plates 18 of the operation case 17, and a pulley 19 is fixed to the other end of the rotating shaft 15.

Also, the pulse motor 2 fixed to the other end plate 18
A timing belt 23 is suspended between a pulley 22 fixed to a drive shaft 21 of the drive shaft 21 and a pulley 19 of the rotating shaft 15, and the display drum 8 is rotated in conjunction with an electric motor 20.

Also, a position detector 24 located on one end side of the display drum 8 to detect the slit 16 of the one end panel mounting plate 11 includes a light emitting element and a light receiving element that receives reflected light emitted from the light emitting element.

Next, the control circuit 26 will be explained with reference to FIG.

Reference numeral 27 denotes a measurement item selection switch, which outputs signals of numbers corresponding to each item, for example, signals of 0 to 7.
The number output from the selection switch 27 is converted into a binary number by the encoder 28, and the number output from the selection switch 27 is converted to a binary number by the first latch circuit 29.
number is retained. In addition, the selection switch 27
When any of these is operated, the instantaneous pulse output is
The OR circuit 30 inputs the signal to a first latch pulse generator 31 , a second latch pulse generator 32 and a delay circuit 33 .

Further, immediately before the number of the selection switch 27 newly operated by the second latch circuit 34 is input to the first latch circuit 29, the first latch circuit 29
The number of the selection switch 27 corresponding to the previous measurement item held in is taken in.

Further, the arithmetic comparison circuit 35 receives the number of the newly operated selection switch 27 and the number of the previously operated selection switch 27 from the first latch circuit 29 and the second latch circuit 34. The rotation direction of the display drum 8 is determined and a rotation direction signal is output. The operation of this arithmetic comparison circuit 35 is shown in a flowchart as shown in FIG. If the value is 0, this means that the same selection switch as the previously operated selection switch has been operated, so an INHIBIT signal is generated to stop the rotation. If the value is other than 0, it is determined whether it is positive or negative, and if it is negative, +4 is added, and if it is positive, -4 is added.
If the value is negative, a rotation direction signal in one direction, for example, clockwise, is output, and if it is other than negative (positive and 0), a rotation direction signal in the other direction, for example, counterclockwise, is output.

Further, when the operation signal of the selection switch 27 is inputted to the delay circuit 33 from the OR circuit 30, the one-shot multivibrator 36 outputs a drive signal by shaping the pulse delayed by the operation time of the arithmetic and comparison circuit 35, etc. The one-shot vibrator 36 is configured to stop operating when the INHIBIT signal is generated. This one-shot multivibrator 36

The driving pulse of the electric motor 20 from 9 is the counter 4.
0 and outputs a pulse signal that shifts the phase of the drive pulse according to the number of windings of the motor 20 and applies it to each winding. For example, if the number of windings in the motor 20 is four, the pulses will be shifted in phase by 90 degrees.

The rotation direction signal from the arithmetic comparison circuit 35 is input to the forward/reverse rotation switching circuit 41, which switches the phase rotation direction of the pulses applied to each winding of the motor 20 from the counter 40, and causes the motor 20 to be rotated by the driver 42. The drive pulse is amplified to a possible level, the electric motor 20 is rotated, and the display drum 8 is
is rotated.

Further, the number of the selection switch 27 corresponding to the measurement item held in the first latch circuit 29 is decoded by a decoder 43, and this decoder 43 selects the sensor corresponding to the number of the selection switch 27 of the position detector 24. 25 light emitting elements are turned on. Further, a predetermined gate of the multiplexer 44 is opened by a position signal corresponding to the number of the selection switch 27 from the first latch circuit 29, and a predetermined position of the position detector 24 is caused to emit light by the rotation of the display drum 8. When the slit 16 of the panel mounting plate 11 of the display drum 8 reaches the position of the sensor 25, the signal is transmitted to the multiplexer 44.
enters the open gate, a stop signal is output, the flip-flop 37 is reset, the motor 20 is stopped, and the display panel 9 displays the measurement item corresponding to the selected selection switch 27 in the display window 4 of the operation panel 1. Display 7 is displayed.

Next, the operation of this embodiment will be explained.

The operation parts 2, 2, 2, 2, of the selection switch 27 arranged on the operation panel 1 according to the measurement item
When any one of 2, 2, 2 is operated, the electric motor 20
is rotated in the rotation direction determined by the rotation direction signal from the arithmetic and comparison circuit 35, and the display drum 8 is rotated by the rotation of the electric motor 20. When the position detector 24 detects the slit 16 due to the rotation of the display drum 8, the electric motor 20 is stopped, and the selected measurement item is displayed in the display window 4 of the operation panel 1.
A display panel 9 on which is formed is located. For example, when measuring vital capacity with a pulmonary function measuring device, the display 7 on the display panel 9 is visually recognized through the display window 4 of the operation panel 1. Then, the operator operates the operation section 6 of the operation switch located under "Preparation" of the display item 5 of the display 7. By this operation, the zero balance of the pneumotachograph in the pulmonary function measuring device is automatically adjusted.
