Which apparatus is used for injecting arterial fluid during the embalming process?

The gravity injector is a commonly used device in the embalming process to inject arterial fluid. This apparatus operates on the principle of gravity to create pressure, allowing the embalmer to introduce the fluid into the arterial system effectively. By positioning the fluid reservoir at a height, the natural pull of gravity facilitates the flow of embalming fluid through the tubing and into the arteries, ensuring that it reaches the intended tissues for preservation and embalming.

This method is favored for its simplicity and reliability in achieving a steady flow of fluid, which is crucial for adequate embalming. The gravity injector allows the embalmer to control the rate of fluid injection, helping to manage the distribution within the body.

The other choices do play roles in the embalming process but are not specifically designed for injecting arterial fluid. For example, a hand pump may be used but often lacks the consistent pressure and control that gravity injectors provide. Pressure machines serve to generate higher and more consistent pressures, which may be beneficial for certain types of cases but aren’t the traditional approach. Lastly, a fluid reservoir simply holds the embalming fluid; while it is essential for the process, it does not perform the function of injecting the fluid on its own.
