Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It will be understood that when an element is referred to as "transferring" another element, it can be directly transferred to the other element or intervening elements may also be present. 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 method for displaying images of a blood vessel imager 100, as shown in fig. 5, comprising:
s1, providing an imager;
specifically, as shown in fig. 1-2, the imager includes a power supply 1, a light source circuit 2, an LED lamp 3, a shielding assembly 4, and a blood vessel positioning hole 5; the LED lamps 3 are arranged around the blood vessel positioning holes 5; the shielding component 4 is connected with the blood vessel positioning hole 5; the LED lamp 3 is electrically connected with the light source circuit 2; the power supply 1 is connected with the light source circuit 2, and electric energy is transmitted to the LED lamp 3 through the light source circuit 2;
s2, placing the blood vessel positioning hole 5 in a human blood vessel detection area; the human body blood vessel detection area is positioned on the surface of the skin where the human body blood vessel is detected;
the invention observes the position of the blood vessel by the light transmitted from the bottom of the skin, and any light entering the positioning hole from the top of the skin is interfered, so medical personnel need to press the skin when the blood vessel positioning hole 5 is placed, and if the material at the periphery of the blood vessel positioning hole 5 does not press the skin, the light source is easy to permeate out through the gap between the material and the skin, thereby causing the interference on observation.
At this time, the size of the blood vessel detection range is the size of the area of the blood vessel positioning hole 5. The shielding component 4 can shield part of external light, so that the skin of a human body within the range defined by the blood vessel positioning hole 5 is dark due to lack of external light;
s3, turning on the LED lamp 3;
s4, observing the image contour in the human blood vessel detection area irradiated by the LED lamp 3, and judging the blood vessel position by showing the contour of the blood vessel appearance.
Because the light source is arranged around the blood vessel positioning hole 5 and is positioned below the periphery of the positioning hole, light emitted by the light source can irradiate the 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 in the range enclosed by the blood vessel positioning hole 5; the higher the density of tissue cells under the skin, the less part of the light passes through the tissue cells, and conversely, the lower density tissue cells appear more transparent due to the greater light passing through;
the shielding component 4 can shield external light to avoid the interference of the external light to the light transmitted from the bottom of the skin, so that the outline of the blood vessel is more obvious. When the medical staff observes, the eyes are positioned on the opposite side of the shielding component 4 to observe, so that the shielding component 4 is prevented from shielding the sight;
the eyes of the health care worker can observe the contour of the tissue under the skin 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 that the blood vessels can show darker color in a light irradiation range compared with other muscle tissues of a human body, the position of the blood vessels is more prominent in the light irradiation range, and therefore medical staff can observe the position of the blood vessels.
In some embodiments, as shown in fig. 6, after S3 and before S4, the method includes the following steps:
s3.1, observing the skin color of the human body in the human body blood vessel detection area; if the skin color is white, the LED lamp 3 is adjusted to a yellow lamp; if the skin color is darker, the LED lamp 3 is adjusted to be dark red; if the skin color is darker, the LED lamp 3 is turned to bright red.
Specifically, the LED lamp 3 can emit light of three colors, which are bright red, dark red, and yellow, respectively. The blood vessel imager also comprises a power supply 1 switch and an LED lamp color adjusting switch 7, and the LED lamp 3 is controlled by the LED lamp color adjusting switch 7 to realize the color change of the LED lamp 3.
The three colors are for different skins, yellow for whiter skins, dark red for darker skins, and bright red for that darkest skin.
In some embodiments, as shown in fig. 7, after S4, the method includes the following steps:
s4.1, observing whether the display degree of the blood vessel contour of the irradiation area is obvious or not; if the blood vessel contour is not obvious, the turning-on number of the LED lamps 3 is increased;
specifically, the number of LED is 20, and the control module can control the independent on/off of each LED lamp 3.
In some embodiments, as shown in fig. 8, the following steps are included after S4.1:
s4.2, if the outline of the blood vessel is not clear enough, the moving part 41 moves to the side far away from the fixed part 42 until the limiting part contacts with the blocking part.
Specifically, as shown in fig. 3 to 4, the shielding member includes a moving member 41 and a fixing member 42; the bottom of the fixing part 42 is fixed at the edge of the blood vessel positioning hole 5; the moving part 41 includes a connecting shaft 411 and a limiting part, and the fixing part 42 includes a connecting hole 421 and a stopping part; the connecting shaft 411 is connected with the connecting hole 421; the limiting part is matched with the stopping part.
The fixed part 42 and the moving part 41 are both of hemispherical film structures; the size of the hemispherical film structure of the moving part 41 is slightly smaller than that of the hemispherical film structure of the fixing part 42, the outer surface of the hemispherical film structure of the moving part 41 can be matched with the inner surface of the latter, so that the hemispherical film structure of the moving part 41 can be hidden in the hemispherical film structure of the fixing part 42, because the moving part 41 is supported by the matching between the connecting shaft 411 and the connecting hole 421, too much external force cannot be received, if the external part is extruded once, the matching structure is extremely easy to damage, and the moving part 41 can be effectively prevented from being damaged when being idle by the design that the hemispherical film structure of the moving part 41 can be hidden in the hemispherical film structure of the fixing part 42.
The moving member 41 is added to shield external light from entering the blood vessel positioning hole 5 as much as possible, thereby reducing interference of the external light with observation of the blood vessel.
Specifically, the limiting portion is specifically a protruding portion, the protruding portion is designed on the outer surface edge of the moving part 41 near the fixed part 42, and the stopping portion is designed on the inner surface edge of the fixed part 42 near the moving part 41. When the moving part 41 moves to a certain distance, the stopping part stops the limiting part to move continuously, so that the moving part 41 is prevented from moving outwards far away from the fixed part 42;
when the user uses the present invention, his/her sight line is to observe the blood vessel positioning hole 5 at the opposite side of the fixing component 42, and the moving component 41 is easily rotated by the connecting shaft 411 and directly moved to the opposite side of the fixing component 42, so as to block the sight line of the user from observing the blood vessel positioning hole 5, and therefore, a structure that a stop part is matched with the limiting part is designed, so as to prevent the moving component 41 from moving to the opposite side of the shielding component 4.
When the stopper comes into contact with the stopper, the moving member 41 completes its maximum movable distance, and the moving member 41 and the fixing member 42 together block more external light, which contributes to more conspicuous outline of the blood vessel.
In some embodiments, the area of the vascular locating hole 5 is 113 square centimeters;
specifically, the diameter of the blood vessel locating hole 5 is 12 cm, so the approximate area of the locating hole is 113 cm;
after the illumination module finishes the detection, if the blood vessel visualization is not clear, the blood vessel positioning hole 5 can be moved to enlarge the blood vessel detection range.
In some technical schemes, the human blood vessel detection area can be selected as a human hand back;
the distance between the blood vessel of the back of the hand of the human body and the surface of the skin is short, so that the observation is easy.
The foregoing is only a few embodiments of the present invention, and it should be noted that other variations and modifications could be made by those skilled in the art without departing from the inventive concept of the present invention, which falls within the scope of the appended claims.
