Automatic blood draw system and method

摘要

Enables cleaning a user's target area around a vein, starting an intravenous catheter placement into a user's vein, drawing blood from a vein, transferring the blood into one or more test tubes and labeling the test tubes. Includes a housing configured to enable a user to fit their arm into the apparatus, a blood pressure cuff, a scanner, a computer system, one or more needles, test tubes and labels. The scanner may scan the user's arm for target veins. Uses an antiseptic solution or antiseptic pads to wipe down a target area, such that a selected needle of appropriate size is lowered and inserted into the targeted vein to draw blood. Embodiments may lower and fill the test tube with the user's drawn blood, label the test tubes with the user's information and dispose the needle into a biohazard removable container.

1. An automatic blood drawing system comprising:
a housing comprising
a computer system coupled with a blood pressure cuff, scanner, memory, one needle or a plurality of needles of varying sizes, at least one actuator for the one needle or the plurality of needles of varying sizes, one or more test tubes, and one or more labels, wherein said computer system is configured to
accept a user's information into said memory; and,wrap the blood pressure cuff around a user's arm and place pressure on the user's arm after the user's information has been accepted into said memory;scan said user's arm to locate and select one or more veins of the user using the scanner after wrapping the blood pressure cuff around a user's arm and placing pressure on the user's arm;obtain an entry angle A to insert the needle, the entry angle being based on the vein selected during the scan of the user's arm;determine a distance D to move a tip of the needle to obtain a vertical depth of the needle in the selected vein and above a lower wall of the selected vein as D=vertical depth/sin(A), after said obtain said entry angle A;inserting the tip of the needle from the one needle or from the plurality of needles of varying sizes at an angle equal to the entry angle A into said selected vein of said one or more veins of the user at by moving the tip of the needle by distance D to locate the needle in the vein selected during the scan of the user's arm and above the lower wall of the vein selected during the scan of the user's arm after determining the distance D, wherein the inserting of the tip of the needle draws blood from said user into said one or more test tubes respectively; and,place one or more labels on said one or more test tubes respectively with said user's information after the tip of the needle has been inserted and after said one or more test tubes are filled with said user's blood.
