Blood vessel lateral light source structure for blood vessel detection

The present invention relates to a mobile phone lateral light source structure for blood vessel detection, in particular to a hidden infrared light source, which can make infrared light uniform and wide-angle light, so as to facilitate infrared light reflected by the image capturing unit, and through the display unit Corresponding to the angiography of the affected part.

Pressing, needle sticking is one of the common medical methods, which is to carry out blood draw, or to deliver blood, drugs and other substances to the human body through injection. The most common one is intravenous injection; however, in general, The medical staff usually observes the position of the blood vessel through the naked eye to perform needle sticking. However, if the blood vessel is too thin, fragile, deep or hardened, it is difficult to identify the position of the blood vessel through the naked eye, especially in the form of body fat. The position of the blood vessel is deep, so the medical staff usually needs to perform multiple needle sticks to find out the exact position of the blood vessel, so that the patient often has to suffer from the needle.

医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医 医Phenomenon, if the injected drug leaks into the subcutaneous tissue by intravenous or intravenous indwelling needle, it will also cause extravasation injury (Extravasation Injury), which is a common case of needle leakage, which may cause skin swelling, pain, burning or blisters. It can even cause deep tissue necrosis.

Therefore, it is known to provide an apparatus for capturing blood vessel images by using an infrared camera, which mainly uses a plurality of infrared light sources to project light onto the surface of a patient's skin, and the lens of the infrared camera is provided with a filter to filter out infrared rays reflected by the skin surface. And by connecting the infrared camera to the infrared camera to display the image captured by the infrared camera, the medical staff can observe the blood vessel image of the patient by the external screen.

However, conventional infrared camera devices that capture blood vessel images have limited illumination angles of the infrared light source and uneven light intensity, which may cause the infrared camera to accurately capture the reflected infrared rays, resulting in time-consuming infrared light source illumination. The adjustment of the angle, and if the intensity of the infrared light is not uniform, will also affect the infrared camera analysis of the infrared signal, resulting in a variety of noise in the presented blood vessel image; and the conventional infrared camera to capture the blood vessel image, the use of The image is captured by the infrared camera, and the captured image is converted into an electronic signal, and the blood vessel image of the patient is presented through the external screen, thereby causing the patient's actual blood vessel distance, position and the presented blood vessel image and position to be stored. There is a deviation, and if the blood vessel image presented is deviated from the fact, it will result in the inability to intuitively puncture the needle into the correct injection position, which also brings the pain of the patient repeatedly rubbing the needle, and the above-mentioned leaky needle is prone to occur. In addition, medical staff must check the image of the external screen several times. For the injection site of the patient, still consumes time.

Furthermore, in view of the need for a surgical procedure, or when the accuracy of detecting a blood vessel position is high, conventional medical devices, including computed tomography, ultrasonic scanning, etc., are provided, and the instruments are expensive and develop. It is time-consuming and labor-intensive. In addition, before the aforementioned angiography, most of the developer needs to be injected for visualization between the tissues, but the use of the developer for inspection often causes many side effects, especially allergies. Or patients with poor renal function may easily cause allergic symptoms, or accumulate developers in the body and are difficult to metabolize. If the above situation is too serious, the patient may suffer from shock and death.

In view of this, the creator specially researched and improved the imaging technology of blood vessels, and improved the above problems with a better design, and after long-term research and development and continuous testing, the creation of this creation began.

Therefore, in order to solve the problem that the medical staff can distinguish the correct needle position by the naked eye before the injection, the patient suffers from the pain of multiple needles, the swelling of the blood drawn part, the bruising, and the injury of the needle. However, the conventional device provides a device for capturing a blood vessel image by using an infrared camera. The infrared light source has a limited illumination angle and uneven light intensity, which causes an adjustment of the illumination angle of the infrared light source, and is easy to cause the presented blood vessel image. There are a lot of noises. In addition, there are deviations between the blood vessel distance, position and the displayed blood vessel image and position. The medical staff needs to repeatedly compare the actual injection site with the blood vessel image, which results in low injection accuracy and lack of labor time. In addition, the medical equipment used for angiography has problems and lack of cost, time and labor, and even more so because of the need to inject the developer first, it is prone to side effects. In severe cases, there will be shock and death. Missing.
