Abstract: Provided are embodiments of a device, having a device body suitable to hold a syringe. The device body can have an elongated member with a distal support and a proximal support. The device further includes a ratcheting rod configured to fit moveably within an open chamber in the elongated member, where the ratcheting rod has a proximal end configured to connect to a plunger of the syringe. The device can include a lever handle hingedly connected to a distal end of the device body, and a ratcheting lever hingedly connected to a distal end of the lever handle and positioned to interact with the ratcheting rod. Compression of the lever handle forces the ratcheting lever to extend the ratcheting rod in a proximal direction and to extract the plunger of the syringe.
