• 12ml Version: Dosage in 1ml increments. Dosage range: 1ml to 12mL
  • 6ml Version: Dosage in 0.5 or 1ml increments. Dosage range: 1ml to 6mL
  • Suitable for liquids of various viscosities
  • Audible click to indicate index position
  • Integrated visual indicators
Filling and Priming:

There are 2 options regarding pre-priming the device.

  1. Sell Product with Dr Doser fully pre-primed up to the nozzle, ready to use.
    • Apply Doser unit to pre filled bottle, pre-prime Dr Doser.

These devices utilise the same technology in different ways, hence;

  • the 6ml is operated by rotating the nozzle head counter clockwise relative to the bottle.
  • the 12ml is operated by rotating a collar at the top of the bottle, relative to the bottle.

To dose the bottle should be in an upright position, the locking tab on the 12ml must be clicked upwards, then a dose can be selected by rotating counter clockwise the collar of the 12ml, or the nozzle head of the 6ml. Each quarter turn adds one increment (0.5 or 1ml) of liquid to the dose. The dispensing tip must then be attached to the nozzle, this opens the nozzle valves which acts as a safety mechanism. The dose can then be dispensed by pressed downwards on the nozzle head. By act of dispensing, the device has been reset to zero. The can the ‘dial up’ another dose, or the dispensing

Dispensing tip:

Redesigned to resemble a child’s dummy, a finger grip area has been added to make this part easier to use. Designed to penetrate the front nozzle valve, this should only be residue left on the tip after it is removed. Fixing the issue of residue left on the nozzle itself.


  • 6ml/12ml main injections moulded parts, 2 smaller injections moulded parts and 2 existingly available valves from mini valve.
  • It is a simpler design, made of fewer parts, that should use less material and be cheaper to manufacture.
  • Both devices operate by siphoning liquid through the special device from the bottom of the bottle.
  • The 6ml fits any standard 28mm glass or polycarbonate bottle threads.
  • The 12ml has been designed to fit the custom designed neck and hence bottle, that allows for the larger size 12ml device.

Design restrictions:
  • Neither version is currently able to be ‘dialled’ backwards. This could be explored in the future if desired.
  • There will be up to 2% of the total volume of liquid that will remain in the bottle
  • Removes a human element of error, safest form of dosing yet.
  • Accuracy, the user can be assured they are getting the correct dose they need.
  • For both versions, once applied to the bottle the Dr. Doser device cannot be removed from the bottle.
  • The dispensing tip must be attached to dispense a dose, otherwise the nozzle cannot be pushed down.
  • We have only performed in house testing on 3D printed versions of the 12ml and 6ml. 
Our results indicate it is more accurate than using existing syringes.
  • Only once have we undertaken qualitative end user acceptance testing at a major Melbourne Hospital. The testing was conducted on a panel of dispensary pharmacists and healthcare professionals.


  • Beverage / Alcohol dispense.
  • Agricultural Chemicals.
  • Precision dispense of laboratory reagents.
  • Large paints and pigments producers.
  • Hospital pharmacies / Aged Care dispensaries.

Intellectual Property:

We have filed a PCT Patent that covers both versions of the device and allows for variations in design.


We have fully functioning 3D printed prototypes of both the 6ml and 12ml device. We plan to commission prototype tooling soon.

Manufacture, sterilisation, assembly and packing:

We are under the impression that in general OTC syrups are not classified as sterile and therefore Dr. Doser is not classified as a Sterile device. Naturally the device would still be produced to high cleanliness standards.

Competitive Advantage:

An example of currently available dosage alternatives.

Austech believe its precision dosage device has a competitive advantage in the areas of; 
1. Dose selection : Both 6ml and 12 ml units feature a single handed dosage selection procedure. Graduations are clearly marked in contrasting colours on the barrel of the device. The user receives  “haptic” – tactile feedback each quarter turn of the device as either a 0.5ml or 1.0 ml aliquot is selected.

2. Ease of dispense : The device is activated by a single finger press. The interaction between moving parts in the internal mechanism have been designed to deliver a smooth, consistent “feel” through the dispense stroke.  

3. Dispense accuracy : Less than 2 percent error across the full dosage range for both devices. 

4. Convenience: Market leaders, GSK and Reckitt Benckiser both provide the end user with proprietary versions of syringe to medicate the end consumer. GSK’s Panadol® product requires the parent or carer to invert the bottle in one hand, while securing the syringe into a gland in the bottle neck with the other hand, in an effort to prevent leaks and / or the ingress of air.

Loose syringes must be washed after use. 
It is not difficult to imagine that small syringes are often misplaced or lost following a single use. 

It is well documented that parents and carers responsible for medication are frequently confused at the point of dose selection and delivery.

5. Security of operation :  Once the device has been activated, dispensing the selected aliquot, it becomes securely locked in the “down” position. (Childproof measure). 

The status quo continues to place a vulnerable group of consumers, infants who are ill, at risk of mis-dosing events.

Uncertainty occurs because of:
i) Different brands and their concentrations.
ii) Complicated measuring cups, syringes and medicine spoons and their graduations.
iii) Poorly written instructions and confusing info-graphics.
iv) Unwieldy ergonomics making single handed dosing impossible.
v) Being forced to use household tea and table-spoons after misplacing loose packed measuring devices.

Austech asserts that its device will not prevent all mis-dosing events, but rather, provides a solution to delivering more of the right dosage, more of the time than current alternatives.
