Abstract
Description
BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a blood vessel projection apparatus using infrared rays, and more particularly, to a blood vessel projection apparatus using infrared rays with more accurate imaging of a blood vessel and improved projection sharpness.
In the medical field, when inserting a needle into a blood vessel located under the skin of a patient, the band is wrapped near the site to expand the blood vessel so that the blood vessel can be visually confirmed, and then the needle is inserted.
However, the medical practice for inserting injections into blood vessels is mainly nurses. Especially, novice nurses are inconveniencing patients when injecting injections into blood vessels because about 50% of patients have had at least one injection stroke.
In particular, in patients with obesity, the elderly, children, and patients who have narrowed blood vessels due to multiple procedures, it is often difficult to find blood vessels by the naked eye and it takes a lot of time to find the blood vessels. .
Accordingly, techniques for photographing a blood vessel of a patient using a camera and projecting the blood vessel to the skin of a patient to thereby facilitate the procedure of inserting the injection needle have been proposed. For example, a technique of infrared ray, Device is being proposed.
There is an unoxidized hemoglobin component in the blood inside the blood vessel, and hemoglobin has a characteristic of absorbing light in the near infrared ray wavelength band. By using the optical characteristics of hemoglobin, near infrared rays are irradiated to the skin of a patient, and images are taken with an infrared camera to obtain images having darker blood vessels relative to skin.
The 'needle guide device' disclosed in Japanese Patent Publication No. 4517004 discloses a technique of displaying a blood vessel image and a needle together on a monitor, in order to help the practitioner's operation using the blood vessel image thus obtained. In Korean Patent Registration No. 0734097, 'Image System Using Infrared Diffusion' discloses a technique of projecting a blood vessel image onto a patient's skin using a projector.
Such techniques are based on accurately extracting a blood vessel in an image taken by an infrared camera and then accurately displaying or projecting it again. In case of inaccurate photographing, display or projection, incorrect blood vessel information is provided to an operator Is an important technical factor in the techniques because it causes the insertion of the needle in the wrong direction.
Accordingly, it is an object of the present invention to provide an apparatus for projecting a blood vessel using infrared rays, which has improved imaging of a blood vessel and improved projection sharpness.
According to the present invention, the above object can be achieved by an infrared ray irradiation module for irradiating infrared rays toward the skin; A camera module for photographing the infrared ray irradiated from the infrared ray irradiation module and reflected from the skin side; An image processing module for extracting a blood vessel from the infrared image taken by the camera module and generating a blood vessel image; A projection module for projecting the blood vessel image generated by the image processing module to the skin; A distance sensor for measuring the distance to the skin; When the distance to the skin is within a predetermined reference distance range based on the measurement result of the distance sensor, the camera module controls the camera module to operate the auto focusing function based on the measured distance measured by the distance sensor And a main controller for controlling the image processing module and the projection module so that the blood vessel image is projected based on the infrared image captured in the auto focusing state.
Here, the distance sensor may include a laser distance sensor.
Further, the main control unit may control the projection module so that the auto-zoom function of the projection module operates based on the measurement distance measured by the distance sensor.
And an output unit for outputting a predetermined alarm; The main control unit may control the output unit to output an alarm when the distance to the skin is within the reference distance range based on the measurement result of the distance sensor.
The output unit may include at least one of a speaker for outputting sound, an alarm lamp for being turned on and off under the control of the main control unit, and a display unit for displaying an image.
The measurement distance may be displayed on the display unit.
According to the present invention, according to the present invention, in order to find the distance to the skin suitable for projecting the blood vessel image, the operator firstly moves the blood vessel projection apparatus to the reference distance range using the laser distance sensor, The operator can more easily find an appropriate distance and obtain an easier and clearer infrared image through the auto focusing function.
In addition, thanks to the auto zoom function of the projection module, a clear vascular image can be projected onto the patient's skin while matching the actual blood vessel.
