Arrangement method of nozzle holes of capturing nozzle of air-borne bacteria capturing apparatus and air-borne bacteria capturing apparatus

Abstract

In order to present an arrangement method of nozzle holes of a capturing nozzle of an air-borne bacteria capturing apparatus in which dents are hardly formed on the carrier in an operation by rotating a petri dish containing a carrier, and sticking air-borne bacteria contained in the air sucked from nozzle holes formed in a capturing nozzle on the surface of the carrier by inertia, nozzle holes 11 of a capturing nozzle 1 of an air-borne bacteria capturing apparatus characterized by rotating a petri dish 3 containing a carrier 2, and sticking air-borne bacteria contained in the air sucked from the nozzle holes 11 formed in the capturing nozzle 1 on the surface of the carrier 2 by inertia are arranged by uniform random numbers, and the density of the nozzle holes 11 per unit area is uniform.

What is claimed is: 
     
         1 . An arrangement method of nozzle holes of a capturing nozzle of an air-borne bacteria capturing apparatus characterized by rotating a petri dish containing a carrier, and sticking air-borne bacteria contained in the air sucked from nozzle holes formed in a capturing nozzle on the surface of the carrier by inertia, wherein nozzle holes are arranged by uniform random numbers, and the density of nozzle holes per unit area is uniform. 
     
     
         2 . The arrangement method of nozzle holes of a capturing nozzle of an air-borne bacteria capturing apparatus according to  claim 1 , wherein by utilizing the average of a plurality of uniform random numbers, the density of nozzle holes per unit area can be disposed in a normal distribution. 
     
     
         3 . An air-borne bacteria capturing apparatus characterized by rotating a petri dish containing a carrier, and sticking air-borne bacteria contained in the air sucked from nozzle holes formed in a capturing nozzle on the surface of the carrier by inertia, wherein nozzle holes are arranged by uniform random numbers, and the density of nozzle holes per unit area is uniform. 
     
     
         4 . The air-borne bacteria capturing apparatus according to  claim 3 , wherein by utilizing the average of a plurality of uniform random numbers, the density of nozzle holes per unit area can be disposed in a normal distribution.
