Abstract
A vessel location assistance device having a housing with a proximal portion and a distal portion, an infrared light emitter adapted to emit infrared light from the housing to a patient and an infrared light receiver adapted to receive backscattered infrared light intensity reflected from the patient, wherein the received backscattered infrared light intensity is converted to a voltage and when the voltage is within a calibrated range the device indicates the presence of a blood vessel. The device may further include at least one wing with a slot for capturing the blood vessel.
Claims23
A vessel location assistance device comprising:
- a housing having a proximal portion and a distal portion, said proximal portion and said distal portion spaced apart along a centerline of said housing, said housing having a top portion and a bottom portion;
- an aperture positioned in said distal portion along said centerline, said aperture penetrating through said top portion and said bottom portion of said housing;
- at least one light associated with said housing;
- three infrared light emitters adapted to emit infrared light from said bottom portion of said housing to a patient and three infrared light receivers adapted to receive backscattered infrared light reflected from the patient;
- said three infrared light emitters and said three infrared light receivers arranged in pairs along equally spaced rows, including a middle row and two remaining rows, each equally spaced row extending perpendicular to said centerline, wherein said middle row of said three rows is aligned with said aperture;
- said three emitters and three receivers arranged in two columns extending along axes equally spaced and parallel to said centerline;
- wherein each pair of said three emitters and three receives is serially and repeatedly energized to emit infrared light and detect backscattered infrared light intensity from said patient when said housing is positioned on or near a patient's skin, each of said detection intensities being converted to a voltage;
- wherein, when a voltage of said middle row is less than a voltage of each of said two remaining rows said at least one light illuminates to indicate the presence of a patient's blood vessel nearest said middle row of said three rows.
