Pull chord manually driven intraosseous injection devices and methods

Abstract

Manually driven intraosseous devices and associated methods are disclosed. The intraosseous device includes a housing and a transmission at least partially disposed within the housing. The transmission includes a first portion and a second portion. The second portion including a manual actuator that is at least partially disposed outside of the housing. The intraosseous device also includes a penetrator assembly releasably connected to the first portion of the transmission. The transmission is configured to transmit a force, which is applied manually to the manual actuator, to the penetrator assembly to rotate the penetrator assembly relative to the housing and to drive the penetrator assembly through a bone into an intraosseous space. The manual actuator is a pull chord and the force is configured to be applied by an operator to a first end of the pull chord to unwind the pull chord and transmit the force to the penetrator assembly.

Dependencies are inferred from the claim text.
