Breath sampling device

Abstract

There is provided a breath sampling tube comprising a deflector adapted to reduce liquid intake into a sampling inlet. There is also provided a breath sampling tube including a deflector adapted to deflect liquid droplets present in breath to reduce liquid at the sampling inlet. There is also provided a breath sampling system including a gas analyzer and a breath sampling tube comprising a deflector adapted to deflect breath to reduce liquid at the sampling inlet. There is also provided a breath sampling system including a gas analyzer and a breath sampling tube comprising a deflector adapted to deflect liquid droplets present in breath to reduce liquid at the sampling inlet.

         40 . A breath sampling system comprising a breath sampling tube and an airway adapter having an interior surface defining an inner channel; said airway adaptor comprising a deflector positioned within the inner channel of said adapter, said deflector comprising one end which is narrower than a second opposing end, such that liquids present in exhaled breath flowing in said adapter is deflected away from a breath sampling opening of said adapter and towards said interior surface, thereby preventing accumulation of liquid in vicinity to the breath sampling opening and minimizing disruption to laminar flow of the breath sample. 
     
     
         41 . The system according to  claim 40 , wherein a cross section of said deflector is essentially in a shape of a cone, a pear, an ovoid, a lens, a diamond, a rectangle or any combination thereof. 
     
     
         42 . The system according to  claim 40 , wherein said deflector comprises a hydrophobic material. 
     
     
         43 . The system according to  claim 40 , wherein said adapter further comprises a breath sampler extending through said interior surface of said adapter, wherein said breath sampler protrudes into said channel, such that an opening of said breath sampler is located within said inner channel, thereby enabling breath sampling by said breath sampler directly from said inner channel. 
     
     
         44 . The system according to  claim 43 , wherein said breath sampler is perpendicular to airflow in said airway adapter. 
     
     
         45 . The system according to  claim 40 , further comprising a capnography. 
     
     
         46 . The system according to  claim 43 , wherein said deflector does not contact said breath sampler. 
     
     
         47 . The system according to  claim 40 , wherein said deflector is located essentially at the center of said channel. 
     
     
         48 . An airway adapter having an interior surface defining an inner channel; said airway adaptor comprising a deflector positioned within the inner channel of said adapter, said deflector comprising one end which is narrower than a second opposing end, such that liquids present in exhaled breath flowing in said adapter is deflected away from a breath sampling opening of said adapter and towards said interior surface, thereby preventing accumulation of liquid in vicinity to the breath sampling opening and minimizing disruption to laminar flow of the breath sample. 
     
     
         49 . The airway adaptor according to  claim 48 , wherein a cross section of said deflector is essentially in a shape of a cone, a pear, an ovoid, a lens, a diamond, a rectangle or any combination thereof. 
     
     
         50 . The airway adaptor according to  claim 48 , wherein said deflector comprises a hydrophobic material. 
     
     
         51 . The airway adaptor according to  claim 48 , further comprising a breath sampler extending through said interior surface of said adapter, wherein said breath sampler protrudes into said channel, such that an opening of said breath sampler is located within said inner channel, thereby enabling breath sampling by said breath sampler directly from said inner channel. 
     
     
         52 . The airway adaptor according to  claim 51 , wherein said breath sampler is perpendicular to airflow in said airway adapter. 
     
     
         53 . The airway adaptor according to  claim 51 , wherein said deflector does not contact said breath sampler. 
     
     
         54 . The system according to  claim 48 , wherein said deflector is located essentially at the center of said channel.
