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. ## Claims ### Claim 1 An intraosseous device comprising: a housing; a transmission at least partially disposed within the housing, the transmission 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, 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. ### Claim 2 (depends on 1) The intraosseous device according to claim 1, wherein 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. ### Claim 3 (depends on 2) The intraosseous device according to claim 2, wherein the hand crank includes a first end, a second end, and an arm extending between the first end and the second end. ### Claim 4 (depends on 3) The intraosseous device according to claim 3, wherein the first end of the hand crank includes a handle. ### Claim 5 (depends on 3) The intraosseous device according to claim 3, wherein the second end of the hand crank includes a cylinder having a top, a bottom, and an outer circumferential surface extending between the top and the bottom. ### Claim 6 (depends on 5) The intraosseous device according to claim 5, wherein the second portion of the transmission includes a gear that is configured to mesh with a gear of the first portion of the transmission to transmit the force between the hand crank and the first portion of the transmission. ### Claim 7 (depends on 1) The intraosseous device according to claim 1, wherein the first portion of the transmission includes a shaft having a first end that is configured to connect to the penetrator assembly. ### Claim 8 (depends on 7) The intraosseous device according to claim 7, wherein the first end of the shaft is keyed. ### Claim 9 (depends on 7) The intraosseous device according to claim 7, wherein a magnet is embedded in the first end of the shaft. ### Claim 10 (depends on 1) The intraosseous device according to claim 1, wherein the first portion of the transmission or the penetrator assembly is provided through at least one tubular bearing of the housing so as to be rotatable relative to the housing. ### Claim 11 (depends on 1) The intraosseous device according to claim 1, wherein the first portion of the transmission is configured to interface with the second portion of the transmission such that the second portion of the transmission is configured to rotate the second end of the shaft. ### Claim 12 (depends on 7) The intraosseous device according to claim 7, wherein the second end of the shaft includes a gear. ### Claim 13 (depends on 7) The intraosseous device according to claim 7, wherein the first portion of the transmission further includes a support plate held within a chamber of the housing, and the support plate supports the second end of the shaft. ### Claim 14 (depends on 1) The intraosseous device according to claim 1, wherein the housing is divided into a first body and a second body that are snap fit together. ### Claim 15 (depends on 14) The intraosseous device according to claim 14, wherein the housing comprises bearings that support the first portion and the second portion of the transmission such that the first portion and the second portion of the transmission are configured to rotate relative to the housing. ### Claim 16 (depends on 15) The intraosseous device according to claim 15, wherein the bearings are integral with the housing. ### Claim 17 (depends on 15) The intraosseous device according to claim 15, wherein the bearings comprise at least one tubular bearing. ### Claim 18 (depends on 17) The intraosseous device according to claim 17, wherein the at least one tubular bearing is one of a plurality of tubular bearings, the plurality of tubular bearings each include an inner circumferential surface, the plurality of tubular bearings are each arranged coaxially along a linear direction extending through the housing, and the inner circumferential surface of each of the plurality of tubular bearings support the first portion of the transmission such that the first portion of the transmission is configured to rotate relative to the housing. ### Claim 19 (depends on 18) The intraosseous device according to claim 18, wherein an inner diameter of the inner circumferential surface of each of the plurality of tubular bearings is larger than an outer diameter of the first portion of the transmission such that the first portion of the transmission is configured to extend through the plurality of tubular bearings. ### Claim 20 (depends on 1) A method of accessing an intraosseous space of a patient comprising: providing an intraosseous device according to claim 1; driving the penetrator assembly through a bone into the intraosseous space of the patient comprising: manually applying a first force to the housing, the first force directing the intraosseous device towards an insertion site on the patient; and manually applying a second force, concurrently with manually applying the first force, to the second portion of the transmission and transmitting the second force to the penetrator assembly to rotate the penetrator assembly relative to the housing.
