Apparatus and method to provide emergency access to bone marrow
First Claim
1. A kit for injecting a unit dose of medication into the bone marrow comprising:
- a housing;
a needle assembly, including an IO needle and a trocar, operable to penetrate the bone and associated bone marrow;
the IO needle and trocar having respective cutting tips aligned for single cutting action;
a drill shaft rotatably disposed within the housing;
a holding mechanism operable to releasably attach the needle assembly to the drill shaft;
the drill shaft operable to connect the needle assembly to a reduction gear assembly disposed within the housing;
the reduction gear assembly operable to rotate the drill shaft;
a motor disposed within the housing;
the motor operable to engage the reduction gear assembly and drive the needle assembly into the bone and associated bone marrow by rotation of the drill shaft;
a battery power supply and associated circuitry disposed within the housing to power the motor;
a strap operable to stabilize the IO needle after the IO needle has been seated in a bone;
needle assemblies in varying sizes; and
unit doses of medications for emergency treatment of patients.
