Description

Technical Field

[0001] This utility model relates to the field of vaccine dispensing device technology, and in particular to a fully enclosed dilution vaccine dispensing device. Background Technology

[0002] Currently, with the continuous expansion of livestock farming in my country, the use of freeze-dried vaccines for immunization or treatment of pigs, horses, cattle, sheep, and poultry is increasing. Vaccines such as those for swine fever, swine erysipelas, swine pneumonia, sheep pox, sheep clostridium, and brucellosis are all made using the freeze-drying method. When using these vaccines, they need to be diluted with special diluents or saline solution. During the manual dilution process, it is easy to cause the virus to spread and splash, which may infect epidemic prevention personnel or veterinary personnel. Therefore, vaccine dilution dispensing devices are often used to administer the vaccines.

[0003] CN201821075930.3 describes a fully enclosed pipeline-based continuous injection device for diluted vaccines. This device connects vaccine vials and diluent vials together, offering advantages such as fully pipelined connection, no need for a circulation tank or other cavities for easy cleaning and disinfection, simple structure, light weight, and easy operation. It eliminates the environmental pollution and risk of virus release caused by manually opening diluent bottles and adding diluent, and solves the problems of operator infection caused by manual vaccine dilution and contamination of vaccines by dust and droplets in the livestock house during dilution addition. However, this device is not convenient for detecting the dilution amount of the vaccine, resulting in relatively low dilution accuracy. Utility Model Content
