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 body without the use of a needle, ensuring that the skin is not punctured during use, thus reducing the risk of infection. Various drugs can be used, inserted into the hypo in vials attached to the end of the instrument.

The 23rd century Federation hypospray resembled the intravenous needles of previous centuries, whilst the 24th century version of the device was more compact, employing 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, 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.
