Hypospray

A hypospray (colloquially, hypo) is a medical device used to inject liquids into the body. The system uses a noninvasive transport mechanism of compressed air to transfer the injectant from the device into the subdermal layer below the skin of the body, or artery. This is done without the use of a needle, ensuring that the skin is not punctured during use, thus reducing the risk of infection or pain at the site of injection. Various drugs can be used, inserted into the hypo in vials attached to the end of the instrument.

The current Federation hypospray is compact with an angled head and rounded tip to transfer the drug more easily. Controls at the injection head set the dosage to be injected. The typical injection site used is the side of the neck, to the carotid artery, but the hypospray can inject even through clothing. Unlike hypodermic needles, the hypospray can be used on multiple patients without worries of spreading blood-borne illnesses. Modern hyposprays can also be used to collect air samples in order to test it or condense air and store it for later use.
