Double-Barreled Injector Assembly for Sequential Livestock Vaccination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injector assemblies are limited in their ability to perform multiple sequential vaccinations with different vaccines efficiently, particularly in large-scale applications such as vaccinating herds or flocks of livestock.
Innovation Solution
A double-barreled injector assembly with a pair of barrels and actuators, where each barrel is connected to a bar with a hand-operated actuator system, allowing for sequential dispensing of two different vaccines by positioning the barrels and using a refill connector for continuous filling, enabling efficient vaccination of multiple animals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single-barreled injector is used for multiple vaccinations, then the device complexity remains low, but the productivity decreases due to repeated device changes and refilling
Solution Approach 1:
The patent combines two separate injector barrels into a single integrated device, allowing simultaneous or sequential administration of two different vaccines without changing devices. The dual-barrel design with shared actuation mechanism merges multiple functions into one unit, directly increasing productivity while controlling complexity through integrated design
Solution Approach 2:
The injector assembly is designed to perform multiple vaccination functions with different vaccines using a single device. The system can administer various vaccine types through two barrels, eliminating the need for separate single-function injectors and thereby improving vaccination throughput across different disease prevention needs
2Loss of time
If manual refilling of single-barreled injectors is performed repeatedly, then the device complexity remains low, but the loss of time increases during vaccination operations
Solution Approach 1:
The dual-barrel design allows one barrel to be pre-filled while the other is in use, enabling seamless transition without refilling interruption. The system prepares the next vaccine dose in advance, eliminating downtime between vaccinations and reducing overall loss of time during herd vaccination operations
Solution Approach 2:
The injector maintains continuous vaccination capability through dual-barrel configuration where one barrel can be used while the other is refilled or prepared. This continuity eliminates idle time between vaccine administrations, keeping the useful action of vaccination ongoing without interruption
3Quantity of substance
If two separate injectors are used for sequential vaccinations, then the device complexity remains low, but the quantity of substance administered decreases due to inefficient vaccine delivery
Solution Approach 1:
The patent merges two vaccine delivery systems into one integrated injector assembly, allowing efficient administration of two different vaccines in sequential or simultaneous fashion. This consolidation improves the quantity of substance delivered by eliminating the waste associated with device changes and ensuring complete vaccine utilization from both barrels

AI summary
A double barreled injector assembly for performing multiple sequential vaccinations includes a pair of barrels, each of which is engaged by a first terminus thereof to a bar and extends from a lower face thereof. A respective agent can be positioned in each barrel. Each barrel has an orifice positioned in a second terminus thereof. A pair of actuators is engaged to an upper face of the bar. Each actuator is operationally engaged to a respective barrel and can be actuated by action of a hand of a user to dispense an associated agent through the orifice of the respective barrel into an animal. The injector assembly allows the user to perform multiple sequential vaccinations with two different vaccines and will be useful in vaccination of herds or flocks of livestock, such as poultry, cattle, and the like.
