Vascular developing glasses structure

The present invention relates to a vascular-developed spectacles structure, and more particularly to a method of enhancing infrared light and developing the blood vessel by a liquid crystal lens to quickly and clearly observe the position of the blood vessel at the infrared ray irradiation.

According to the process of performing medical treatment by the nursing staff, the blood, the liquid medicine and the like are delivered to the human body through various injection methods, and the most common one is intravenous injection. However, according to statistics, whether it is performed When taking blood or injecting, the average number of needles per person needs to be 2.4 times, in order to smoothly insert the needle of the syringe into the appropriate blood vessel position, that is, the blood vessel is too thin, fragile, deep or hardened, so it is difficult for medical personnel to distinguish it by the naked eye. The position of the needle can be correctly inserted, especially in the body fat position, because the blood vessel position is deep, so the patient often has to suffer from the needle.

In addition, due to the way the medical staff judges the position of the blood vessels by the naked eye, it is often impossible to complete the blood drawing or injection process with a single needle. In addition, the patient's blood vessels are too thin and other factors, which are not only easy to puncture the blood vessels, but also cause pumping. The blood area is swollen and bluish. If the injected medicine leaks into the subcutaneous tissue by intravenous or intravenous indwelling needles, it will also cause extravasation injury (Extravasation Injury), which is a common case of needle leakage, which may cause skin swelling and pain. Hot or blisters can even cause deep tissue necrosis in severe cases.

The prior art provides a device for capturing a blood vessel image by using an infrared camera, which mainly uses a plurality of infrared light sources to project light onto a 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 using the external screen; the image must be captured by the infrared camera before use. After converting the captured image into an electronic signal, the patient's blood vessel image is presented through the external screen, causing the patient's actual blood vessel distance, position and the displayed blood vessel image and position to be deviated, and the presented blood vessel Once the image is deviated from the facts, it will result in the inability to intuitively puncture the needle into the correct injection position. This will also bring the patient the pain of repeated needles and the above-mentioned leaking needle. In addition, the medical staff must have multiple times. Compared with the image of the external screen and the part of the patient to be injected, it still takes a lot of work. .

Moreover, in view of the need for a surgical procedure, or when the accuracy of detecting a blood vessel position is high, conventional medical devices are provided, including computer tomography, ultrasonic scanning, etc., and the instruments are expensive to manufacture and consume in the development process. In the absence of time and labor, in addition to the above-mentioned 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 has specially researched and improved the structure of vascular-developed glasses, and has been improving the above problems with a long-term design, and after a long period of research and development and continuous testing, the creation of this creation has begun.

The reason is that this creation is mainly to solve the problem that the medical staff can hardly distinguish the position of the needle from the naked eye before the injection, which causes the patient to suffer from multiple needles, swollen blood, blood, and needle damage. Phenomenon, even if the device provides a device for capturing blood vessel images by using an infrared camera, there is a deviation between the actual blood vessel distance, the position and the displayed blood vessel image and position, and the medical staff needs to repeatedly compare the actual injection site with the blood vessel image, resulting in The injection accuracy is low and the labor time is lacking. Moreover, all kinds of medical equipment used for angiography have problems and lack of cost, time and labor, and even easier to inject the developer first. Side effects, in severe cases, there will be shock and death.

In order to achieve the above object, the creator provides a vascular developing spectacles structure, comprising: a spectacles body provided with at least one infrared ray irradiation unit and a photographic unit, the infrared ray irradiation unit is for projecting infrared rays, and the photographic unit Corresponding to receiving an image reflected by the infrared light; the photographing unit is provided with a filter lens, wherein the filter lens is for enhancing infrared light; and at least one liquid crystal lens is disposed on the lens body, and the liquid crystal lens system is Coupled in the photographing unit, the liquid crystal lens develops an image received by the photographing unit.

According to the vascular development spectacles structure described above, the filter lens is for absorbing infrared light having a wavelength of from 780 nm to 1400 nm.

The vascular development spectacles structure further includes a control unit, one end of which is coupled to the infrared ray irradiation unit, and the other end is coupled to a sensing unit, and the sensing unit senses the ambient light source and transmits the signal To the control unit, the control unit is configured to adjust the intensity of the illumination of the infrared irradiation unit.

According to the vascular development spectacles structure described above, the infrared ray irradiation unit is an infrared LED lamp.

According to the vascular development spectacles structure described above, the infrared ray projected by the infrared ray irradiation unit is near infrared ray.

According to the vascular development spectacles structure described above, the infrared ray irradiation unit projects infrared rays at a wavelength of between 780 nm and 1400 nm.

According to the vascular development spectacles structure described above, a power supply unit is coupled to the infrared ray irradiation unit, the photographic unit, and the liquid crystal lens.

The vascular development spectacles structure further includes a switch member coupled to the power supply unit, the switch member for opening and closing the infrared ray irradiation unit, the photographing unit, and the liquid crystal lens.

According to the vascular development spectacles structure described above, the spectacles system is provided with two liquid crystal lenses.

With the above arrangement, since the filter lens strengthens the infrared light, and the present invention penetrates the skin through the infrared rays, the blood filter absorbs and reflects through the filter lens to facilitate the receiving of the photo unit, and the liquid crystal lens is received by the lens unit. The blood vessel developed by the liquid crystal lens is indeed equivalent to the ratio observed by the human eye, so that the proportion of the blood vessel development is not distorted, so that the medical staff can easily and intuitively wear the lens body. Knowing the position of the blood vessel of the patient, thereby greatly improving the blood drawing or the accuracy of the injection; in addition, the illumination intensity of the infrared irradiation unit can be automatically adjusted according to the ambient light source, and the advantages and functions of the high operational convenience and applicability are more highly utilized. .
