페이지 인쇄The Adjustment of backpressure
The back-pressure adjustment is made by the DC-Valve in addition to the level of the water in the Container. When
used with the mask only, there will be a DC backpressure adjusted by the user.
Description of Use
Before the First Use
Thoroughly hand-wash the DC-Valve with water and a small amount of house detergent; then rinse and dry.
Assembly
For doctorVOX Apparatus insert the straight (slightly conic) end of the device into the inhalatory outlet and slightly
push it until a firm closure occurs. You can keep the adjusting knob any side.
For maskVOX, insert the ridged end of the device into the outlet of the maskVOX and feel the 'click' sensation when it
is fixed properly.
For disassembling device:
Slightly rotate and pull the DC-Valve from the outlet tube of the doctorVOX device or,
Slightly bend and pull the DC-Valve from the outlet of the maskVOX device.
How It Works
The physiological effect of the DC-Valve is based on continuous (DC) backpressure. Thanks to this continuous
backpressure, the work of the vocal folds becomes easier and safer. It helps vocal muscle developing and closure of
functional glottic gaps when used properly. At the same time, the respiratory muscles work properly and strengthen,
as they have to overcome the water resistance in addition to the tuning.
Phonation into the maskVOX mounted DC-Valve
When used with maskVOX , continuous backpressure is on duty.
After mounting the DC-Valve to the outlet of the maskVOX properly (please feel the dovetailing between two
devices)
Wear the mask properly and adjust the predefined backpressure by the adjusting knob of the DC-Valve.
Phonation into the doctorVOX Apparatus mounted DC-Valve
When used with doctorVOX Apparatus, the water level in the Container should be at the level 2 in the beginning.
After mounting the doctorVOX DC-Valve to the inhalatory end (marked as 'OUT'); take the phonatory end of the
tube (marked as "IN" ) slightly between your teeth (Do not bite or narrow the silicone tube).
The tongue lies relaxed behind the lower teeth. The lips enclose the end of the tube with a "kiss" without pressure,
but airtight.
Now blow and let the water bubble regularly. Increase the backpressure as described by the supervisor (clinician or
pedagogue)
Phonate into tube with the same regular bubbling pattern. (The primal sound is supposed to be found for this)
Hold this tone and let the water bubble in a stable manner.
Take care to keep your cheeks loose and vibrating with the bubbling. The jaw muscles should also be relaxed.
Imagine your neck and throat wide and soft.
Exercise with the primal sound for few minutes, three to ten times throughout the day.
It helps developing your voice when used properly with a professional guidance.
Respiratory training with doctorVOX Apparatus mounted DC-Valve
Fill the Container with warm water (Not above 50°C/ 122
Adjust the amount of liquid so that the water level does not exceed the level 2.
Place the upper part to the container and lock the device by locker clips.
Mount the DC-Valve to the inhalatory end of the doctorVOX device
FOR THE INHALATORY TRAINING:
Enclose the inhalatory end of the DC-Valve between your lips (be careful for the teeth injury)
Adjust the resistance by the adjusting knob of the DC-Valve
Breathe in slowly through the inhalatory tube end. Be careful not to inhale hot water by breathing too fast and too
much!
FOR THE EXHALATORY TRAINING (Positive Expiratory Pressure- PEP)
Enclose the exhalatory end of the tube (marked as "OUT") between your lips (be careful for the teeth injury, use
the silicone tip))
Adjust the resistance by the adjusting knob of the DC-Valve
Breathe out slowly through the exhalatory tube end. Be careful not to push too much!
If you feel dizzy, stop exercise. Take a break for a few minutes and try again: breathe more slowly and take a break
after each exhalation until you feel the renewed urge to inhale.
