Abstract

A blood sample obtaining device including a first arm, a second arm, a light source and a pressure applying head. The first arm and the second arm are operably connected to each other. The light source is mounted with respect to the first arm. The pressure applying head is mounted with respect to the second arm.

Claims

1. A blood sample obtaining system comprising:

a blood sample obtaining device comprising;

a first arm;

a second arm that is operably connected to the first arm;

a light source mounted to the first arm, wherein the light source is adapted to emit light; and

a pressure applying head mounted to the second arm, wherein the pressure applying head has an open region formed therein and wherein the pressure applying head is rotatable with respect to the second arm, wherein the first arm and the second arm are configured to move to a closed configuration to retain a body portion in a stationary position with respect to the first arm and the second arm, and wherein the light source is configured to illuminate the body portion through the open region to aid a user in identifying a location for blood sampling; and

a puncturing device that is configured to puncture the body portion.

2. The blood sample obtaining system of claim 1, wherein the first and second arms are biased away from each other.

3. The blood sample obtaining system of claim 2, wherein a biasing force is adjustable.

4. The blood sample obtaining system of claim 1, and further comprising a protective cover mounted at least partially over the light source, wherein the light is visible through the protective cover.

5. The blood sample obtaining system of claim 1, wherein the light source is configured to be activated using a technique selected from the group consisting of when the first arm and the second arm are moved from an open configuration toward a closed configuration, by movement of at least one of the first arm and the second arm from a stationary position, by an on/off switch or combination thereof.

6. The blood sample obtaining system of claim 1, wherein the open region on the pressure applying head is configured to allow blood to flow into a puncture site.

7. The blood sample obtaining system of claim 1, wherein the pressure applying head is capable for use as a guide for a puncture site.

8. The blood sample obtaining system of claim 1, and further comprising at least one guiding mark on the pressure applying head.

9. The blood sample obtaining system of claim 1, and further comprising a magnifying means operably connected to at least one of the first arm and the second arm.

10. The blood sample obtaining system of claim 9, wherein the magnifying means is movable between a use position and a storage position.

11. The blood sample obtaining system of claim 1, and further comprising a battery mounted with respect to at least one of the first arm and the second arm, wherein the battery is operably connected to the light source.

12. The blood sample obtaining system of claim 1, wherein rotation of the pressure applying head with respect to the second arm is configured to change an orientation of the open region with respect to the second arm.

13. The blood sample obtaining system of claim 1, wherein the pressure applying head further comprises a slot formed therein and wherein the slot is configured to receive a blood collection device.

14. A method for obtaining a blood sample comprising:

providing a blood sample obtaining device comprising a first arm and a second arm that are operably connected to each other, a light source mounted to the first arm, and a pressure applying head rotatably mounted to the second arm, wherein the light source is adapted to emit light and wherein the pressure applying head has an open region formed therein through which the light may be viewed;

positioning a portion of a body from which a blood sample is to be obtained between the first arm and the second arm;

illuminating the body with the light to identify a location from which the blood sample will be obtained;

moving the first arm and the second arm to a closed configuration to retain the body in a stationary position with respect to the first arm and the second arm; and

puncturing the body to obtain the blood sample.

15. The method of claim 14, and further comprising providing at least one guide mark on the pressure applying head to identify a location from which the blood sample is to be obtained.

16. The method of claim 14, and further comprising providing a magnifying means on the second arm to facilitate identifying a location from which the blood sample is to be obtained.

17. The method of claim 14, and further comprising biasing the first arm and the second arm away from each other.

18. The method of claim 14, wherein the light source is activated using a technique selected from the group consisting of when the first arm and the second arm are in a closed configuration, by contact with an ear, by movement of the first arm and the second arm from a stationary position, by an on/off switch or combination thereof.

19. The method of claim 14, wherein the pressure applying head comprises only one point for compression thus allowing blood flow into a puncture site.

20. The method of claim 14, and further comprising mounting a battery with respect to at least one of the first arm and the second arm and operably connecting the battery to the light source.

21. The method of claim 14, wherein rotation of the pressure applying head with respect to the second arm changes an orientation of the open region with respect to the second arm.

22. The method of claim 14, and further comprising rotating the pressure applying head with respect to the second arm.

23. The method of claim 14, and further comprising:

providing a blood collection device;

providing a slot in the pressure applying head;

extending the blood collection device through the slot, wherein the slot is configured to hold the blood collection device in a stationary position with respect to the pressure applying head; and

collecting the blood sample with the blood collection device.

24. A blood sample obtaining system comprising:

a tissue stabilization device comprising;

a first arm;

a second arm that is operably connected to the first arm;

a light source mounted to the first arm, wherein the light source is adapted to emit light; and

a pressure applying head mounted to the second arm, wherein the pressure applying head has an open region formed therein, wherein the pressure applying head is rotatable with respect to the second arm, wherein the pressure applying head further comprises a slot, wherein the first arm and the second arm are configured to move to a closed configuration to retain a body portion in a stationary position with respect to the first arm and the second arm, and wherein the light source is configured to illuminate the body portion through the open region to aid a user in identifying a location for blood sampling; and

a blood collection device configured to be placed through the slot.

25. The blood sample obtaining system of claim 24, wherein the slot is configured to hold the blood collection device.
