Description

[0001] The present invention relates to a blood vessel searching apparatus using a transmission illumination,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a blood vessel searching apparatus using transmission illumination, and more particularly, to a blood vessel searching apparatus using transmission illumination for easily finding a blood vessel of a body through light of a light emitting diode.

In general, arteries are high blood pressure because they are the channels through which blood is ejected from the heart, while the blood pressure is relatively low because the veins are circulated and sucked back into the heart due to the pumping action of the heart. Therefore, when an artery is injured, the blood comes out as if the blood is spouting, but the vein is lower than the artery, so blood pressure is not so deep, and there is no serious bleeding. Normally, when injecting or drawing blood to the human body, the injection needle is pushed into the vein to find the vein, and the medicine is directly injected into the blood vessel or the blood is drawn through the vein.

Conventionally, when injecting blood or drawing an injection to find a vein in a human body, a certain portion of the arm is bound using a rubber band, and when the vein protrudes to the outside, an injection needle is pierced into the vein and an injection or blood is drawn. Therefore, conventionally, when a vein is searched, it is troublesome and uncomfortable to find a vein with mental stress and pressure on the body because the patient injects the blood or injects the blood while bundling the arm with the rubber band to protrude the vein.

In order to solve this problem, Korean Patent Registration No. 10-0834542 has proposed a vein measuring device for measuring vein using an electrode method. However, in this electrode method, the reference potential at the electrode is kept constant It is difficult to easily find the position of the vein.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a blood vessel searching apparatus using transmission illumination capable of accurately and easily finding the position of a blood vessel located in a body.

According to another aspect of the present invention, there is provided an apparatus for searching for blood vessels using transmission illumination, comprising: a band unit mounted on a user's body; A pressing part coupled to the band part and pressing a peripheral skin area around a search target skin area for searching for a blood vessel; A light irradiating unit installed in the pressing unit between the pressing unit and the peripheral skin area to irradiate light into the skin of the peripheral skin area; And a lens unit provided in the pressing unit to enlarge and display the search target skin area.

The pressing portion includes a main body coupled to the band portion, and a pressing rib extended from the main body to occupy the peripheral skin region.

And the lens unit is vertically rotatably mounted on the pressing unit.

The light irradiating unit includes an LED package provided below the pressing unit and a power supply unit provided in the pressing unit to supply power to the LED package.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a blood vessel searching apparatus using transmission illumination according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show a blood vessel searching apparatus 1 using transmission illumination according to the present invention. 1 to 4, a blood vessel searching apparatus 1 using transmission illumination includes a band unit 10 mounted on a user's body; A pressing unit 20 coupled to the band unit 10 and pressing a peripheral skin area around the search target skin area for searching for a blood vessel; A light irradiation unit installed in the pressing unit 20 between the pressing unit 20 and the peripheral skin area and irradiating light into the skin of the peripheral skin area; And a lens unit 60 provided in the pressing unit 20 to enlarge and display the search target skin area.

The search target skin region described below refers to a certain region of the skin where the blood vessel is located when injecting the drug solution into the blood vessel through injection or drawing the blood from the blood vessel and the peripheral skin region is a predetermined distance Or a certain area around the adjacent area.

The band portion 10 is formed in a ring-shaped band structure having one side opened so as to be worn on an arm or a leg of the user's body. The band portion 10 is made of a material having elasticity so as to be able to grip an arm or a leg regardless of the thickness of the user's arms or legs. The band portion 10 may be formed of a circular band of rubber material which can be stretched.

The pressing portion 20 is coupled to the band portion 10 and includes a main body 30 coupled to the band portion 10 and an annular pressing portion 32 extending from the main body 30 to occupy the peripheral skin area, And ribs 40.

The main body 30 is formed in a rectangular shape having a space portion 31 formed therein and a passing slit 32 passing through both side surfaces is formed so that the band portion 10 can pass therethrough. An operation button 55 is provided on the upper surface of the main body 30 to sequentially turn on or off the power from the power supply part 53 of the light irradiation part to be described later, Exposed. The main body 30 is provided at the rear end side of the main body 30 to prevent the main body 30 and the pressing portion 20, which will be described later, from slipping along the user's body while the band portion 10 is mounted on the user's arm, Preventing protrusion 33 protruding downward from the bottom of the main body 30 and extending in the width direction of the main body 30. [ The slip prevention protrusion 33 is bent at a predetermined angle in accordance with the bending of the arm or the leg and is formed of a rubber material having elasticity so that the body 30 can be held by the user even when the user does not hold the body 30 with one hand. It is possible to free both hands of the user because it is prevented from being detached from the legs.

The pressurizing rib 40 is bifurcated to form an elliptical shape from the distal end side of the main body 30 so as to occupy the peripheral region of the skin region to be searched, that is, the peripheral skin region, and an opening 40a is formed at an end thereof. The upper and lower portions of the pressurizing ribs 40 are opened to allow the user to look into the skin region to be searched above the pressing ribs 40.

The bottom surface of the pressurizing rib 40 is convex downward so as to press the peripheral skin area and to relatively bump the search target skin area upward.

The bottom surface of the end portion of the pressing rib 40 is further provided with a non-slip pad 41 for preventing the pressing rib from sliding in contact with the skin.

The lens unit 60 is rotatably coupled to the main body 30 through the hinge 61 so as to be able to enlarge and see the search target skin region surrounded by the pressing rib 40. [

The light irradiation part is provided on the pressing part 20 and irradiates light into the skin of the peripheral skin area. The light irradiation part includes an LED package 51 installed on the bottom surface of the pressing rib 40 contacting the peripheral skin area, A power supply unit 53 installed in the space 31 inside the LED package 51 to supply power to the LED package 51 and a power supply unit 53 exposed from the power supply unit 53 to the LED package 51, And is transmitted from the power supply unit 53 to the LED package 51 in accordance with the operation of the operation button 55 and the operation button 55 for sequentially changing the amount of light emitted from the LED package 51 And a control module (not shown) for controlling the magnitude of the current. For example, the control module operates the LED package 51 once by pressing the operation button 55 once, and gradually increases the amount of light emitted from the LED package 51 by pressing the operation button 55 once To decrease the value of the current applied to the LED package 51 so as to increase the value of the current applied to the LED package 51 or gradually decrease the amount of the light.

The LED package 51 is inclined to the pressurizing rib 40 so that light can be emitted to the skin region to be searched when the pressurizing rib 40 presses the peripheral skin region. The power supply unit 53 may be a non-rechargeable battery or a rechargeable secondary battery. Alternatively, the power supply unit 53 may be a voltage regulator that receives external power, adjusts the voltage according to the operating voltage of the LED package 51, May be applied.

The LED package 51 is equipped with an LED chip array emitting light of 590 nm and 630 nm wavelength.

When an LED light source of a specific wavelength is penetrated deeply into the skin, the light is absorbed by the hemoglobin in the blood, thereby distinguishing it from the skin cell. Blocking the blood supply to the artery blocks OxyHb (oxyhemoglobin), which contains oxygen, and increases the amount of DeoxyHb (deoxyhemoglobin). Conversely, when the blocked blood is supplied, OxyHb (oxyhemoglobin) increases and returns to normal.

At this time, hemoglobin is bright red when it is bonded with oxygen, dark red when it loses oxygen, and the position of the blood vessel is selected by the change of hemoglobin absorbance in the human body when oxygen is sufficient or not enough by using LED light source of a specific wavelength . In other words, when passing through a bright red blood containing a lot of oxygen by a specific wavelength range of an LED light source, it absorbs a lot of light of 590 nm. The intensity of light transmitted through this wavelength band is different from that of OxyHb By visualizing the change in absorbance of DeoxyHb, the position of the blood vessel can be found.

Here, the light of 630 nm wavelength is used to give a change of light absorbance to the skin when the skin is browned or the skin color is different than the general person.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the exemplary embodiments, but, on the contrary, It will be appreciated that other embodiments are possible.

Accordingly, the scope of the true technical protection of the present invention should be determined by the technical idea of the appended claims.
