Syringes are commonly used tools in medicine, chemistry, biology and other fields, and are widely used. The following are some common applications of syringes:
Administration: Doctors or nurses usually inject drugs into the blood vessels, muscles or subcutaneous tissues of patients with syringes. This drug delivery method can quickly deliver the drug to the patient's body to achieve therapeutic effect.
Sample extraction: In chemical and biological experiments, syringes are often used to extract samples. For example, using a syringe can easily extract a certain amount of liquid or gas from the experimental material for further analysis or detection.
Hemodialysis: syringe can be used for hemodialysis. The blood in the dialyzer enters the dialyzer through the syringe and is purified in the dialyzer to remove the waste and excess water in the body, and then returns to the patient through the syringe.
Injection smears: In the field of biology and medicine, syringes can be used to prepare cell injection smears for observing and studying cell morphology and function.
Measuring volume: The syringe can usually be used to measure the volume of liquid, because there is a clear scale line in the syringe, which can accurately measure a certain volume of liquid. This is very common in chemical and biological experiments.
In general, syringes are widely used in medicine, chemistry, biology and other fields. It is a very practical tool.
