Abstract
The head carried venous puncture leading instrument is one venous imaging system comprising infrared emitter, infrared receiver and head carried display. The infrared emitter consists of several near infrared LEDs of 800-850 nm emitted wavelength. The infrared receiver is one low-irradiation high-resolution white and black video camera with one 800 nm infrared filter before its lens. The display is one head carried spectacles connected to the video camera. The present invention makes it possible to watch the veins on dorsum of hand clearly and is used in venous puncture to facilitate the vein searching.
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 wear-type venipuncture inducer of blood vessel 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 wear-type 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 the wear-type display device at the moment.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 wear-type display device.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 that the video camera that the height of 800nm infrared ray colour filter is resolved is housed before the camera lens, and display is one and wears the video glasses, and it links with the video camera of supporting height parsing.
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 the wear-type display device.
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. near infrared ray receptors, 3. camera lenses among the figure
4. infrared ray colour filter 5. wear-type display devices 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 wear-type display device 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 display is one and wears the video glasses, and it links with the video camera of supporting height parsing, and image presents by wear-type display device 5.For the difficult patient who looks for of blood vessel, when concrete operations, connect with the mains 6 earlier, put on display again, allow patient hold infrared launcher 1, patient places camera lens 3 preceding infrared ray colour filter 4 times with hands then, the near infrared ray that semiconductor light-emitting-diode sends penetrates staff, hemoglobin absorption peak in the staff venous blood is the highest, so develop on wear-type display device 5, at this moment the nurse just can find patient's blood vessel accurately by the development in the wear-type display device.
Claims (4)
1. wear-type venipuncture inducer, the vein blood vessel imaging system of forming by infrared launcher and corresponding near infrared ray receptor and wear-type display device.
2. a kind of wear-type venipuncture inducer according to claim 1, 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.
