Abstract

Certain exemplary embodiments provide a device comprising a band comprising a magnetic material. The magnetic material can comprise Neodymium (Nd—Fe—B) and/or Samarium Cobalt (SmCo). Certain exemplary embodiments provide a method comprising utilizing a magnetic band to restrain motion of a vein in a human, wherein a blood sample is taken from the vein or a medication is injected into the vein.

Claims (16)

1 . A device, comprising:

an open-ended band configured as a cuff to couple to a forearm of a user, the cuff comprising a first magnet and a second magnet, the second magnet being spaced apart from the first magnet along a length of the cuff;

an aperture positioned between the first magnet and the second magnet, the aperture providing an opening for insertion of a needle into a vein of the user;

wherein the first magnet and the second magnet are oriented with like magnet poles facing one another across the aperture to generate a repulsive magnetic field extending between the first magnet and the second magnet and through the aperture into soft tissue of the forearm;

wherein the magnetic field applies a magnetic force to diamagnetic blood within the vein positioned beneath the aperture, the magnetic force generating a tensioning effect on the vein that stabilize blood flow

within the vein for withdrawal of the blood sample.

2 . The device of claim 1 , wherein:

the magnetic material comprises Neodymium (Nd—Fe—B).

3 . The device of claim 1 , wherein:

the magnetic material comprises Samarium Cobalt (SmCo).

4 . The device of claim 1 , wherein the device is a wearable device.

5 . The device of claim 4 , wherein the device is worn on a wrist of the user.

6 . The device of claim 1 , wherein the device allow a user to locate and stabilize the vein.

7 . The device of claim 1 , wherein the device is open-ended band with shaped ends.

8 . The device of claim 1 , wherein the first and second magnets are an earth magnetic material.

9 . The device of claim 1 , wherein the band holds the vein in a particular position for the user to inject a medication into the vein.
