Anesthetic delivery device

摘要

According to an example embodiment, a delivery device may include a needle and a pump operatively coupled to the needle, the pump having an expanded configuration and a collapsed configuration, the pump being biased to its expanded configuration such that fluid stored in the pump will exit the pump via the needle in response to pressure being applied to the pump, and in response to the pressure being released from the pump, the pump is configured to receive fluid from outside of the delivery device via the needle.

主权项

1. A delivery device comprising:
a needle including a needle shaft defining a lumen; a pump operatively coupled to the needle, the pump including a bulbous member, the bulbous member configured to store fluid, the lumen of the needle shaft being in fluid communication with the bulbous member, the pump having an expanded configuration and a collapsed configuration, the bulbous member including a flexible material, the flexible material biasing the pump to the expanded configuration, the fluid stored in the bulbous member configured to exit the bulbous member of the pump via the needle in response to a user applying pressure to the pump, and in response to the pressure being released from the pump, the pump is configured to return to the expanded configuration causing fluid from outside of the delivery device to enter the bulbous member via the needle; a handle coupled to the bulbous member, the bulbous member being disposed between the handle and the needle, the handle including a valve; and a reservoir removably coupled to the handle, the valve permitting a transfer of fluid from the reservoir to the bulbous member in a first direction.
