Abstract
A venipuncture guider is composed of a near-infrared LED emitter consisting of several LEDs with 850 nm of near-infrared wavelength, a near-infrared receiver which is a camera with a 800-nm filter in the front of its length for high white-black definition, and a monitor for correctly displaying vanual position after a patient grasps said emitter and its hand is positioned before said chroamtic filter.
Description
Technical field
The present invention relates to a kind of assistance medical personnel and carry out intravenous instrument, especially can when intravenous injection, help to find the venipuncture inducer of blood vessel clinical.
Background technology
Intravenous injection extensive use clinically brought into play important effect in treatment disease and redemption patient life, but again owing to some patient self, blood vessel is tiny, difficulty is looked for; Also have some traumatic patients because severe loss of blood, blood vessel is full, causes that the nurse can not find blood vessel when intravenous injection, has missed treatment opportunity.
Summary of the invention
The purpose of this invention is to provide and a kind ofly make things convenient for the nurse to carry out intravenous venipuncture inducer in clinical, for the difficult patient who looks for of blood vessel, the nurse can find patient's blood vessel accurately by the development on monitor.
For achieving the above object, the vein blood vessel imaging system that the present invention is made up of near-infrared semiconductor diode discharger and corresponding near infrared ray receptor and monitor.
Adopt said structure, because principle of the present invention is: near infrared ray penetrates the tissue of human body, and the hemoglobin absorption peak in venous blood is the highest, so can develop on monitor.
In sum, advantage of the present invention is: principle is simple, alleviated nurse's working strength, improved the success rate of intravenous needle puncture.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the present invention.
Figure is a structural representation of the present invention.
1. semiconductor light-emitting-diodes, 2. infrared receivers, 3. camera lenses among the figure
4. infrared ray colour filter 5. monitors 6. power supplys
The specific embodiment
Among the figure, the vein blood vessel imaging system that the present invention is made up of near-infrared semiconductor diode discharger and corresponding near infrared ray receptor and monitor.Near-infrared semiconductor diode discharger is made up of the semiconductor light-emitting-diode 1 of several 5, and it sends near infrared wavelength is 850nm.Near infrared ray receptor 2 is high video cameras of resolving of black and white low-light (level) that 800nm infrared ray colour filter 4 is housed before the camera lens 3, and image presents by monitor 5.For the difficult patient who looks for of blood vessel, when concrete operations, plug in 6 earlier, allow patient hold near-infrared semiconductor diode discharger, patient places camera lens 3 preceding infrared ray colour filter 4 times with hands then, and the near infrared ray that semiconductor light-emitting-diode sends penetrates staff, and the hemoglobin absorption peak in the staff venous blood is the highest, so develop on monitor 5, at this moment the nurse just can find patient's blood vessel accurately by the development in the monitor.
Claims (3)
1. venipuncture inducer, the vein blood vessel imaging system of forming by near-infrared semiconductor diode discharger and corresponding near infrared ray receptor and monitor.
2. a kind of venipuncture inducer according to claim 1 is characterized in that: near-infrared semiconductor diode discharger is that the semiconductor light-emitting-diode by several 5 is formed in parallel, and it is 850nm that each light emitting diode sends near infrared wavelength.
3. a kind of venipuncture inducer according to claim 1 is characterized in that: the near infrared ray receptor is the high video camera of resolving of black and white low-light (level) that 800nm infrared ray colour filter is housed before the camera lens.
