Abstract
A venous vessel finder is a venous vessel imaging system composed of infrared transmitter, near infrared receiver and monitor. Said infrared transmitter consists of several infrared diodes connected parallelly. Said near infrared receiver is a low-illumination high-resolution camera with a 800-mm infrared filter in the front of its lens. It can be used to easily find the venous vessel on the back of hand.
Description
Technical field
The present invention relates to a kind of medical personnel of help and carry out intravenous instrument, especially can when venipuncture, help to find the vein blood vessel of blood vessel to look for device clinical.
Background technology
In the clinical vein piercing process, because some patient's 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, multiple threading a needle, and this just makes patient not only physical distress but also psychentonia, also doctor-patient relationship is also very nervous in addition.The home and abroad document does not have relevant report at present by retrieval, does not have the instrument of assisting venipuncture on the market yet.
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 vein blood vessel in clinical to look for device, for the difficult patient who looks for of blood vessel, the nurse can find patient's blood vessel accurately by the development on monitor.Venipuncture inducer can make hand back vein, especially naked eyes and the touch vein that is difficult to seek, move towards unclear comes into plain view, can greatly lower medical personnel in the use and implement work difficulty in the venipuncture procedure, the misery of avoiding blindness inserting needle, repeated localised puncture to bring to patient, having reduced doctor-patient dispute effectively, also is the good aid of venipuncture teaching simultaneously.
For achieving the above object, the vein blood vessel imaging system that the present invention is made up of infrared launcher and corresponding near infrared ray receptor and monitor.Infrared launcher is formed in parallel by several near infrared diode, and it is 800-850nm that each infrared-emitting diode sends ultrared wavelength.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
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.Make hand back vein, especially naked eyes and the touch vein that is difficult to seek, move towards unclear comes into plain view, can greatly lower medical personnel in the use and implement work difficulty in the venipuncture procedure, the misery of avoiding blindness inserting needle, repeated localised puncture to bring to patient, having reduced doctor-patient dispute effectively, also is the good aid of venipuncture teaching simultaneously.This product can be widely used in that all kinds of hospitals, community clinic, family ward and medical colleges and schools etc. are any to have required unit to venipuncture.
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. infrared launchers, 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 infrared launcher 1 and corresponding near infrared ray receptor 2 and monitor 5.Infrared launcher 1 is formed in parallel by several near infrared diode, and it is 800-850nm that each infrared-emitting diode sends ultrared wavelength.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 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 infrared launcher 1, 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. a vein blood vessel is looked for device, the vein blood vessel imaging system of being made up of infrared launcher and corresponding near infrared ray receptor and monitor.
2. a kind of vein blood vessel according to claim 1 is looked for device, it is characterized in that: infrared launcher is formed in parallel by several near infrared diode, and it is 800-850nm that each infrared-emitting diode sends ultrared wavelength.
3. a kind of vein blood vessel according to claim 1 is looked for device, it 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.
