Abstract

Apparatus and methods are provided to penetrate a bone and associated bone marrow using a powered driver. The apparatus may include a housing; a drive shaft comprising a first end disposed within the housing and a second end extending from the housing, the second end of the drive shaft configured to releasably engage the intraosseous device; a motor disposed within the housing and rotatably engaged with the drive shaft; a rechargeable power supply configured to supply power to the motor; an electrical charging circuit configured to recharge the rechargeable power supply; and a visual indicator indicating a status of the rechargeable power supply. The apparatus may also include an electrical power circuit configured to measure one of torque and current flow through the motor.

Claims

1. An apparatus for inserting an intraosseous device into a bone and associated bone marrow, comprising:

a housing;

a drive shaft comprising a first end disposed within the housing and a second end extending from the housing, the second end of the drive shaft configured to releasably engage the intraosseous device;

a motor disposed within the housing and rotatably engaged with the drive shaft;

a rechargeable power supply configured to supply power to the motor;

an electrical charging circuit configured to recharge the rechargeable power supply; and

a visual indicator indicating a status of the rechargeable power supply.

2. The apparatus of claim 1, further comprising a sensor configured to measure an amount of power available in the rechargeable power supply.

3. The apparatus of claim 2, wherein the visual indicator comprises a plurality of lights, the plurality of lights comprising:

a first light configured to indicate that the amount of power is below a first threshold amount; and

a second light configured to indicate that the amount of power is above a second threshold amount; and

a third light configured to indicate that the rechargeable power supply is being recharged.

4. The apparatus of claim 2, wherein the visual indicator comprises a digital display indicating the amount of power available in the rechargeable power supply as a percentage of full charge of the rechargeable power supply.

5. The apparatus of claim 4, wherein the digital display further indicates an estimated number of remaining uses of the apparatus based on the amount of power available in the rechargeable power supply.

6. The apparatus of claim 2, wherein the sensor comprises one of:

a voltmeter and an amp meter.

7. The apparatus of claim 1, wherein the electrical charging circuit comprises an electrical contact configured engage with a portion of a charging receptacle.

8. The apparatus of claim 7, further comprising:

a handle; and

a removable cap disposed on one end of the handle;

wherein the rechargeable power supply is disposed in the handle;

wherein the electrical contact is disposed on the removable cap.

9. The apparatus of claim 1, further comprising an impact device configured to store and deliver rotational energy to a gear assembly,

wherein the motor is configured to generate the rotational energy when the rechargeable power supply supplies power to the motor;

wherein the gear assembly is attached to the drive shaft;

wherein the gear assembly rotates the drive shaft when the impact device delivers the rotational energy to the gear assembly.

10. The apparatus of claim 9, further comprising a first electrical power circuit configured to detect a current change between the impact device and the rechargeable power supply.

11. The apparatus of claim 10, wherein the first electrical power circuit is configured to reduce power from the rechargeable power supply to the motor when the first electrical power circuit detects the current change,

wherein the current change indicates that apparatus has inserted the intraosseous device into the bone and associated bone marrow.

12. The apparatus of claim 1, further comprising a second electrical power circuit configured to measure one of torque and current flow through the motor.

13. The apparatus of claim 12, wherein the second electrical power circuit is configured to reduce power supplied by the rechargeable power supply to the motor when the torque or current flow measured by the second electrical power circuit is greater than a threshold level.

14. The apparatus of claim 13, further comprising a fourth light configured to indicate when the torque or current flow measured by the second electrical power circuit is greater than the threshold level.

15. The apparatus of claim 1, further comprising a fifth light extending from the housing, wherein the fifth light is configured to illuminate an insertion site of the intraosseous device.

16. An apparatus for inserting an intraosseous device into a bone and associated bone marrow, comprising:

a housing;

a drive shaft comprising a first end disposed within the housing and a second end extending from the housing, the second end of the drive shaft configured to releasably engage the intraosseous device;

a motor disposed within the housing and rotatably engaged with the drive shaft; and

a first electrical power circuit configured to measure one of torque and current flow through the motor.

17. The apparatus of claim 16, further comprising a power supply configured to supply power to the motor,

wherein the first electrical power circuit is configured to reduce power supplied by the rechargeable power supply to the motor when the torque or current flow measured by the first electrical power circuit is greater than a threshold level.

18. The apparatus of claim 17, further comprising a light configured to indicate when the torque or current flow measured by the first electrical power circuit is greater than the threshold level.

19. The apparatus of claim 17, further comprising an impact device configured to store and deliver rotational energy to a gear assembly,

wherein the motor is configured to generate the rotational energy when the power supply supplies power to the motor;

wherein the gear assembly is attached to the drive shaft;

wherein the gear assembly rotates the drive shaft when the impact device delivers the rotational energy to the gear assembly.

20. The apparatus of claim 19, further comprising a second electrical power circuit configured to detect a current change between the impact device and the rechargeable power supply, wherein the second electrical power circuit is configured to reduce power from the power supply to the motor when the second electrical power circuit detects the current change.
