BIOquant® NS is a medical device developed by Yalong Trade, s.r.o. 

BIOquant® NS uses a patented nasal applicator that utilizes 

optimally-designed laser light source and optic dimensions. 

The device produces wavelength 650nm of semiconductor diode laser light. 

Purpose of use:

This medical device is intended for the physical laser irradiation of blood at wavelength of 650nm through nasal cavity for the purpose of improving rheological properties of blood. 


  • The mechanism of main effect is physical and is based on the absorption of photons in the irradiated mucous membrane and blood flowing in that mucous membrane.  
  • The method is intranasal. The mucous membrane of nasal cavity has numerous blood vessels with rich and relatively slow blood flow. The light from device is irradiation during application the blood flowing in irradiated mucous membrane. 


  • Improved blood rheology, i.e. viscosity and elasticity and deformability of red blood cells. 

Application areas:

BIOquant® NS can be used at home, hospitals, and out-patient departments. 


Use of the device is contraindicated in states associated with bleeding (hemorrhagic states) and in active cancer under treatment. Also, the device must not be used by pregnant women and users with decreased blood coagulation. 


Some users are more sensitive to laser light. This sensitivity can be genetic or caused by drugs interactions. For those with increased sensitivity to light caused by medicaments or by genetic predispositions, the device must be used with short application time and power. We recommend during the first application to use program P5 with continuous light to test sensitivity of users to light. In the event of negative reactions, use of device must be stopped. 


  • Improved blood rheology, i.e. viscosity and elasticity and deformability of red blood cells.
