Sensors 

The FreVAX™ device is equipped with several sensors to guarantee an optimal vaccination result. 

8.1.

 

Position Sensor 

This sensor allows for continuous control of the correct holding 

position of the device. Once the trigger has been pushed, before 

allowing liquid to be drawn into the device the position sensor will 

check if it is held upright in order to avoid drawing in air. If the device 

is held in the correct angle, which is indicated by the small circle being 

inside the big circle, liquid from the attached bottle will be drawn in. 

Once the device is fully loaded with liquid, the holding position is no 

longer relevant until the trigger is activated again.  

 

Please note: When using the tubing adapter to deliver vaccine, no position sensor reading is needed 

because there is no bottle mounted on top of the device. In this case, the position sensor can be 

disabled (

). 

8.2.

 

Air Detection Sensor 

This sensor measures whether fluid or air is drawn into the device. If 

air is drawn in, e.g. by emptying the bottle and not fitting a new one 

in time, a warning “Air detected” is shown. Afterwards, only rinsing is 

possible, indicated by blue flashing LED bars, until the air exits at the 

injection head. This takes a minimum of 3 rinsing cycles, as the liquid 

circuit has a volume of a little less than 6 ml and one rinsing cycle 

moves a volume of 2 ml. After the rinsing process, you will be able to 

vaccinate again (indicated by white flashing LED bars). 

8.3.

 

Nozzle Sensor 

This sensor enables an extra safety precaution when using the injector. Once the FreVAX™ device is 

ready for vaccination (white flashing LED bars), push and hold the trigger. When the device is applied 

to the skin of the piglet, the safety sleeve around the injection head will slide back, releasing the 

vaccine. If either the trigger is not pushed or the safety sleeve around the injection head does not 

slide back, no vaccine will be released. This allows for a high level of user safety. 

Furthermore, the nozzle sensor measures  if the minimum  contact 

time between device and piglet 

for administration of the full dose

 is 

fulfilled. If the injector is released too early, implicating an underdose, 

the device will give an optical warning via red flashing LED bars and a 

written notification on the display.

Vaccination Process 

 

Press the trigger to load the device. The position sensor indicates 

the position of the bottle in the holder of the FreVAX™.
