Abstract

The present invention provides an improved arterialized earlobe blood collection device, and an improved process for blood analysis. The device and the process of the invention can be used in many unsual and/or risky situations, including collecting arterialized blood in space missions under microgravity environment and within ambulances or the like. The process of the present invention enables easier and faster blood analysis, since the blood collector device of the invention is coupled with an analyzing apparatus so as no blood or needle manipulation is required.

Claims

1. An arterialized earlobe blood collector device comprising:

a blood collecting module comprising at least one cartridge for blood collecting;

a cutting module comprising an ophthalmic surgery blade in an aluminum body and at least one screwing system having a blade depth adjusting means; and

a device body comprising a back part having a quick fastener mechanism for opening and closing the device, an anatomic ear attachment system, and a sealing system.

2. The device according to claim 1, wherein said quick fastener mechanism comprises four pins attached to the back part of the device, and a cap comprising four L-shaped depressions, wherein each of the pins are connected to a respective one of the L-shaped depressions for closing.

3. The device according to claim 2, wherein said blade has a thickness between 0.1 mm and 0.4 mm.

4. The device according to claim 3, wherein said blade has a thickness of 0.15 mm.

5. The device according to claim 3, wherein the blade is spring-pushed, and further comprising a plastic pin which releases the spring-pushed blade via a cam mechanism.

6. The device according to claim 3, further comprising a window enabling visualization of blood during collection of blood.

7. The device according to claim 2, wherein the blade is spring-pushed, and further comprising a plastic pin which releases the spring-pushed blade via a cam mechanism.

8. The device according to claim 7, further comprising a window enabling visualization of blood during collection of blood.

9. The device according to claim 2, further comprising a window enabling visualization of blood during collection of blood.

10. The device according to claim 1, wherein the blade has a thickness between 0.1 mm and 0.4 mm.

11. The device according to claim 10, wherein said blade has a thickness of 0.15 mm.

12. The device according to claim 10, wherein the blade is spring-pushed, and further comprising a plastic pin which releases the spring-pushed blade via a cam mechanism.

13. The device according to claim 10, further comprising a window enabling visualization of blood during collection of blood.

14. The device according to claim 1, wherein the blade is spring-pushed, and further comprising a plastic pin that releases the spring-pushed blade via a cam mechanism.

15. The device according to claim 14, further comprising a window enabling visualization of blood during collection of blood.

16. The device according to claim 1, further comprising a window enabling visualization of blood during collection of blood.

17. A blood analysis process wherein arterialized blood is collected by means of a device comprising:

attaching the device to an earlobe via a means for attaching the device to an earlobe;

sealing the device to an earlobe via a means for sealing the device to an earlobe, wherein the sealing device avoids leakage of blood between the device and an earlobe;

collecting blood via a means for collecting blood, said means for collecting blood comprising at least one cartridge and a screw system having a blade depth adjusting means; and

avoiding blood manipulation and conducting blood analysis in vitro once collected blood is located on the at least one cartridge that is directly associated to an analysis device,

wherein the device comprises a back part and a means for quick fastening of the back part of the device.

18. The blood analysis process according to claim 17, further comprising a blade and using said blade to cut the earlobe, wherein cut depth of the blade is adjustable by means of retraction or extension of an exposed part of the blade.

19. The blood analysis process according to claim 18, further comprising, after collecting blood, coupling the at least one cartridge to an analyzer to avoid blood manipulation.

20. The blood analysis process according to claim 17, further comprising, after collecting blood, coupling the at least one cartridge to an analyzer to avoid blood manipulation.
