The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
In order to facilitate understanding for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples.
The present invention provides a vascular imaging apparatus 100; the lighting device comprises a battery module 1, a lighting module 2 and a control module 3 which are connected in sequence; the lighting module 2 comprises a light source 21, a shielding component 22 and a blood vessel positioning hole 23; the light source 21 is arranged around the vascular locating hole 23; the shielding component 22 is connected with the blood vessel positioning hole 23.
Firstly, estimating the approximate position of a human blood vessel, placing a blood vessel positioning hole 23 at the position, wherein the size of the blood vessel detection range is determined by the area of the blood vessel positioning hole 23, and the shielding component 22 can shield part of external light so that the human skin within the range defined by the blood vessel positioning hole 23 appears dull due to lack of the external light;
the light source 21 of the illumination module 2 is turned on through the switch of the control module 3, because the light source 21 is arranged around the blood vessel positioning hole 23 and is positioned below the periphery of the positioning hole, light emitted by the light source 21 can irradiate a human body part under the skin through the skin, the light can be scattered when encountering human tissue cells under the skin, and the scattered light can be irradiated through the skin within a range enclosed by the blood vessel positioning hole 23;
the higher the density of tissue cells under the skin, the less the portion of the tissue cells that the light passes through, and conversely, the more transparent the tissue cells with the lower density, the contour of the tissue under the skin can be observed by the eyes of the health care provider by the light scattered out of the skin; blood vessels under the skin are not easy to pass through due to high density of the blood vessels, so the blood vessels are dark in the light irradiation range, the position of the blood vessels is more prominent in the light irradiation range, and the position of the blood vessels can be observed by medical staff.
The shielding assembly 22 can shield the external light to avoid the interference of the external light to the light transmitted from the bottom of the skin, so as to make the contour of the blood vessel more obvious. When the medical staff observes, the eyes are positioned on the opposite side of the shielding component 22 to observe, and the shielding component 22 is prevented from shielding the sight.
After the illumination module 2 finishes the detection, if the blood vessel visualization is not clear, the blood vessel detection range can be expanded by moving the blood vessel positioning hole 23 to test other positions.
In the invention, the blood vessel position is observed through the light transmitted from the bottom of the skin, and any light entering the blood vessel positioning hole 23 from the top of the skin is interfered, so that the medical staff needs to press the skin when the blood vessel positioning hole 23 is placed, and if the material at the periphery of the blood vessel positioning hole 23 does not press the skin, the light source 21 can easily permeate through the gap between the material and the skin, thereby causing the interference on the observation.
The invention irradiates the light emitted by the lighting module 2 into the body tissue under the local skin area encircled by the blood vessel positioning hole 23, and observes the outline of the blood vessel by utilizing the illumination characteristic of the blood vessel, thereby finding the position of the blood vessel.
In some embodiments, the light source 21 includes no less than 2 LED lamps 211.
Specifically, the brightness of the light source 21 is also determined by the size of the blood vessel positioning hole 23, and if the area of the blood vessel positioning hole 23 is larger, the brightness of the light source 21 correspondingly required is also larger; the light source 21 is formed by combining a plurality of LED lamps 211, and the brightness of the light source 21 can be determined by adjusting the number of the LED lamps 211.
In some embodiments, the LED light 211 includes three colors, which are bright red, dark red, and yellow.
The three colors are for different skins, yellow for whiter skins, dark red for darker skins, and bright red for that darkest skin.
