Abstract
The invention discloses a directing apparatus for venous blood vessel piercing, which is a venous blood vessel image-forming system comprising a rectangular near-infrared transmitting tube, a cylindrical near infrared ray receiver, a square monitor and a DC power source. During real time operation, the image signals can be transmitted to the monitor.
Description
Technical field
The present invention relates to a kind of vein blood vessel guiding puncture instrument, in particular, relate to a kind of novel medical apparatus and instruments, it can help medical personnel in real time, dynamically to show the back of the hand and dorsalis pedis vein, naked eyes and touch are difficult to seek and localized vein blood vessel, and all clear demonstrations of energy come into plain view.
Background technology
The vein blood vessel puncture technique is widely used clinically, has brought into play important effect in treatment disease and redemption patient life, and still owing to some patient's self dissection reason, blood vessel is tiny, difficulty is looked for; The patient who also has is because fat, and blood vessel also is difficult for seeking, and also has some patients because the wound severe loss of blood, and blood vessel is full, causes medical personnel's venipuncture failure when treatment easily, increases patient's misery, has missed treatment opportunity when rescuing the heavy patient.
Summary of the invention
The purpose of this invention is to provide a kind of vein blood vessel guiding puncture instrument that in clinical, helps medical personnel to carry out venipuncture, tiny for blood vessel, not full, the deep patient of anatomical position, the nurse can find patient's blood vessel accurately by the development on monitor, increases the success rate of medical personnel's venipuncture.
For achieving the above object, the present invention is by rectangle near-infrared transmitting tube, cylindrical near infrared ray receptor, square monitor and the vein blood vessel imaging system that dc source is formed.Dc source is a chargeable lead-acid battery of 12V.The near-infrared transmitting tube is that the semiconductor light-emitting-diode by several 5mm is formed in parallel, and it sends near infrared wavelength is 850nm, and is connected with dc source.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 8mm optical lens, the outfan of near infrared ray receptor is connected with monitor, input is connected with dc source, the input of monitor is connected with the near infrared ray receptor, and the other end is connected with dc source.Image presents by monitor.
Principle of the present invention is: the specificity absorption spectrum that utilizes deoxyhemoglobin, through opto-electronic conversion and Flame Image Process, the image of the back of the hand and dorsalis pedis vein blood vessel is presented on the screen of monitor real-time dynamicly, so that medical personnel implement venipuncture for the patient accurately and rapidly.
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. near-infrared transmitting tubes, 2. semiconductor light-emitting-diodes, 3. infrared receivers, 4. optical lens, 5. infrared ray colour filter, 6. video cameras, 7. connecting rods, 8. monitors, 9. dc sources among the figure
The specific embodiment
Among the figure, the vein blood vessel imaging system that the present invention is made up of rectangle near-infrared transmitting tube 1, cylindrical near infrared ray receptor 3, square monitor 8 and dc source 9.Dc source 9 is the chargeable lead-acid batteries of 12V.Near-infrared transmitting tube 1 is made up of the semiconductor light-emitting-diode 2 of several 5mm, and it sends near infrared wavelength is 850nm, is connected with dc source 9.Near infrared ray receptor 3 is high video cameras 6 of resolving of black and white low-light (level) that 800nm infrared ray colour filter 5 is housed before the 8mm optical lens 4, and near infrared ray receptor 3 links to each other with monitor 8 by connecting rod 7.The outfan of near infrared ray receptor 3 is connected with monitor 8, and input is connected with dc source 9, and the input of monitor 8 is connected with near infrared ray receptor 3, and the other end is connected with dc source 9.For the difficult patient who looks for of blood vessel, when concrete operations, plug dc source 9 earlier, allow patient hold near-infrared transmitting tube 1, patient places camera lens 4 preceding 5 times about 25cm of infrared ray colour filter with the back of the hand then, infrared ray colour filter 5 is just in time only to allow the 850nm near infrared ray pass through, then pass through the optical lens of 8mm again, picture signal is sent on the high video camera 6 of resolving of black and white low-light (level), video camera 6 changes picture signal into the signal of telecommunication again and is sent on the monitor 8, because the deoxyhemoglobin in the venous blood is the highest near infrared absorption peak, monitor 8 will clearly show the image of the endovascular deoxyhemoglobin of venous patient, and its image is shown as black strip shade on square monitor 8.This moment, medical personnel can find patient's blood vessel 8 times accurately and rapidly at square monitor, and medical personnel's highly difficult repeatedly venipuncture is in the past become fast and simply.
Claims (4)
