Google X’s delivery drones probably won’t be bringing you champagne anytime soon.

A patent filed in June 2013 and awarded to Alphabet’s GOOG, -2.37% GOOGL, -2.41% Google on Tuesday indicates that the company is more interested in using drones for transporting medical equipment.

The patent states that the drone would have a control system configured to provide medical support, such as delivering a defibrillator.

Automated External Defibrillators can cost $2,000 to $3,000 to install, and some laws require multiple AEDs to be placed in a building. AEDs also require periodic maintenance, thus can continue to add up in cost.

But with a number of AED-carrying drones on standby, in a downtown area for example, Google anticipates it would often be able to respond to an emergency much more quickly than it would take for someone to retrieve an AED from the far reaches of a building, according to the patent.

And AEDs maintained by Google would be able to be inspected with greater ease than if they were left in the building.

In October 2015, Aaref Hilaly, a partner with Sequoia Capital, tweeted out video of a prototype Google drone dropping off a small package in Arizona. Google X head Dave Vos said the company hopes it can be operating a delivery service with Google-made drones by 2017.

Google isn’t the only company wanting to use delivery drones for the medical field.

Silicon Valley startup Matternet is using drones to deliver medical supplies to rural areas.

“It’s much more cost-, energy- and time-efficient to send [a blood sample] via drone, rather than send it in a two-ton car down the highway with a person inside to bring it to a different lab for testing,” said Andreas Raptopoulos, founder and CEO of Matternet.
