It's okay to give a cat a human syringe. Cats' greatest nemesis is the syringe. Whether it's a big cat or a kitten, the vet will walk in with a syringe, and the cat will tremble in fear.
The emergence of the syringe was an epoch-making revolution in the field of medical appliances, and the process of injecting a gas or liquid with a needle is called injection.
Use of syringes
Syringes can also be used for medical devices containers such as some chromatography in which scientific instruments are injected through a rubber diaphragm. Injecting gas into a blood vessel will result in an air embolism. The way to remove air from a syringe to avoid an embolism is to turn the syringe upside down and tap it gently, then squeeze out a little liquid before injecting it into the bloodstream.
In situations where precision is the primary concern rather than germs, such as in quantitative chemical analysis, glass syringes are still used because of their low margin of error and smooth movement of the pusher. Syringes can also be used to inject some juice into meat to improve flavor and texture when cooking meat, or into pastries when baking. The syringe can also be used to refill ink into cartridges.
