Abstract
Manually driven intraosseous devices and associated methods are described. 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 includes 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 hand crank that is configured to be manually cranked by an operator to transfer rotational force to the first portion of the transmission.
Core Innovation
The invention relates to an intraosseous device having a housing, a transmission at least partially disposed within the housing, and a penetrator assembly releasably connected to a first portion of the transmission. The transmission includes a first portion and a second portion, where the second portion includes a manual actuator that is at least partially disposed outside the housing. A force applied manually to the manual actuator is transmitted 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 invention further includes a transmission first portion that includes a shaft having a first end configured to connect to the penetrator assembly, and the magnet is embedded in the first end of the shaft. In an additional embodiment, the first portion includes a support plate held within a chamber of the housing, and the support plate supports a second end of the shaft. These structural elements position and support the shaft while enabling rotation of the penetrator assembly relative to the housing.
Claims Coverage
The document provides two independent claims that cover a manually driven intraosseous device with a housing, a two-portion transmission with an external manual actuator, and a penetrator assembly releasably connected to the first transmission portion. Across the independent claims, the inventive feature set includes manual force-driven rotational penetration through bone into an intraosseous space, with shaft connection to the penetrator assembly and additional shaft interface/support characteristics.
Manually driven intraosseous rotation and bone penetration via two-portion transmission
A housing; a transmission at least partially disposed within the housing, including a first portion and a second portion, the second portion including a manual actuator that is at least partially disposed outside of the housing; and a penetrator assembly releasably connected to the first portion of the transmission, wherein the transmission is configured to transmit a force, 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.
Magnet embedded in shaft first end
The first portion of the transmission includes a shaft having a first end configured to connect to the penetrator assembly, wherein a magnet is embedded in the first end of the shaft.
Shaft second-end support plate within housing chamber
The first portion of the transmission includes a shaft having a first end configured to connect to the penetrator assembly, wherein the first portion further includes a support plate held within a chamber of the housing, and the support plate supports a second end of the shaft.
Overall, the independent claims are directed to a manually driven intraosseous device that converts manual force applied to an external manual actuator into rotational movement of a penetrator assembly that drives through bone into an intraosseous space. The claims further specify a magnet embedded in the first end of the shaft configured to connect to the penetrator assembly, and a support plate held in a housing chamber supporting the second end of the shaft.
