Healthy animals are necessary for efficient stockyard production. Disease and other bacterial conditions thrive in close quarters; making regular vaccination for all livestock a natural pre-requisite. However, implementing and documenting consistent injections for all animals is tedious, expensive and, in some cases, hazardous. To solve these problems, Acushot, an innovative veterinary design company, designed an automated, needle-free injection gun for mass livestock vaccination. The design required a linear bearing system to absorb recoil. Acushot™ turned to Colpitt Designs, who recommended PBC Linear's Simplicity® plane bearings for the task.
Typically, hand-held needle injections were used for vaccinating the animals in the stockyards and barnyards; however, with thousands of animals coming through production at once, successfully and safely supervising the injections became an increasing concern. Acushot's new system eliminated needles, removing the possibility for an unsafe employee needle-slip. The unit also enhances sanitary conditions. The battery powered injection unit can be used hundreds of times without risk of cross contamination to the animals.
For a rapid prototype and possible added refinements to their design, Acushot™ turned to Colpitt Designs—a third party engineering firm. Colpitt worked to reduce components and assemble the triggering/injection system by using a gas cylinder with varying degrees of strength to provide up to 600 pounds of force. The system also automatically saves each dose with a time stamp for accurate vaccination records. The cylinders are designed to inject the vaccines to the same recommended depth as a typical needle that would have been used on a range of animals. The injector can be set at a low threshold of 0.2cc and deposited just in the skin of the animal or set up to 2.5cc and injected to the recommended depth into the muscle of the animal.
