Increase the vaccination success rate

In the traditional inoculation box, the sealability is not very good, even if it looks absolutely tight in the inoculation box. When the person's arm is inoculated into the inoculation box, the air in the box will occupy the volume of the arm. Conversely, when the arm is drawn from the inoculation box, dirty air from the outside will enter the inoculation box. Inoculation personnel in the vaccination process, arm stretching, shrinking time, so that the inoculation box and the outside air when the time out, which is bacteria stains and cause hidden contamination of an important reason. In view of this, a small improvement should be made to the inoculation box, which is now described below. Place a sealed plastic bag on the inoculation box (a hole is left on the bag and tightly sterilized during inoculation) to make it communicate with the bleed hole on the inoculation box. The volume of the plastic bag is preferably 1/10 of the inoculation box (excessive disinfection is not complete). The plastic bag is placed over the window so that the bag is completely sealed from the outside. When disinfected, no sterilizing aerosol that does not penetrate into the hole can enter the plastic bag through the ventilation hole in the upper part of the inoculation box so that the inoculation box and the bag can reach the aseptic state. In this way, at the time of inoculation, the arms go in and out of the inoculation box, forming bumps and pockets of the bag, forming an air exchange between the bag and the inoculation box. Unclean air from the outside can not enter the inoculation box, thereby increasing the success rate of inoculation and reducing the occurrence of hidden dyeing bags. China Agricultural Network Editor
