Vein Sensing Device

technical field

The invention relates to a vein sensing device, in particular to a vein sensing device that uses infrared light sensing technology to display vein images.

Background technique

In traditional Western medicine, there are thousands of types of drug treatments. These include oral medicines, injection medicines, drip-type medicines or suppositories, etc., which are all common methods.

However, administration by injection has long been an integral part of medical practice. In general, the most common form of injection is the safest way to give the drug through an IV. The reason for this is that blood pressure in the veins is lower and therefore less prone to the risk of substantial blood loss following invasive treatments.

However, the traditional intravenous injection relies on the experience of medical staff. Apart from the experience, there are still many patients who have difficulty finding blood vessels in clinical practice. The reason may be that the natural blood vessels are thinner; it may also be that the body fat is too high, and the blood vessels are not easy to be detected by the naked eye from the outside of the skin. Although it is also possible to force the veins to appear by means of banding, etc., their effect is still very limited.

Based on the above reasons, modern vein sensing devices have actually been developed in modern medicine. The principle of traditional vein sensing devices is mainly to use the principle that the absorption rate of hemoglobin in blood vessels to near-infrared light is different from that of other tissues. Through image processing after imaging with near-infrared light, the position of subcutaneous blood vessels is projected and displayed on the skin surface. It enables medical staff to clearly identify the distribution of blood vessels under the patient's skin.

In more detail, in the vein sensing device of the conventional technology, when the near-infrared light irradiates the body part, the infrared light of a specific wavelength will be absorbed by the blood vessels. The more absorption, the less reflection, so the image projected on the skin will appear black; while other tissues have less absorption, the more reflection. Therefore, it will present a higher brightness color light.

However, the traditional vein sensing device finally displays the blood vessel image on the skin surface by projecting visible light. Therefore, the projected blood vessel image is likely to deviate from the actual position of the venous blood vessel. As a result, the needle stick will not reach the correct injection site.

As shown in FIG. 1 , the embodiment of FIG. 1 shows the structure of the vein sensing device 10 of the present invention, which mainly includes a pedestal 100 , a transmitter 200 , a detection arm 300 , a first receiver 400 a and a display 500 .

Wherein, the transmitter 200 is arranged on the pedestal 100 . The transmitter 200 in this embodiment selects an infrared light transmitter. And the transmitter 200 is closely attached to the illuminated part H and emits infrared light R1 to illuminate the illuminated part H. In this embodiment, the wavelength of the infrared light R1 is between 780-1400 nanometers (nm), and the illuminated portion H is a human palm. However, in fact, the irradiated part H can also be a common intravenous injection site such as thigh, buttock, upper arm, etc., which is not limited in the present invention.

The detection arm 300 of this embodiment is disposed on the pedestal 100, and the detection arm 300 is used to carry the first receiver 400a. In this embodiment, the first receiver 400a is an infrared light camera, and the first receiver 400a receives the infrared light image R2a emitted by the illuminated part H. The infrared light image R2a is actually an image converted from the infrared light R1 passing through the irradiated portion H. As shown in FIG. Among them, the infrared light image R2a contains the image information of many tissues after being irradiated with the infrared light R1.

In this embodiment, the infrared light image R2a actually includes a first luminance interval image, a vein luminance interval image, and a second luminance interval image. Wherein, the brightness of the first brightness interval image is higher than the vein brightness interval image, and the vein brightness interval image has a higher brightness than the second brightness interval image.

Taking the tissue that may be included in the actual irradiated portion H as an example, since almost all of the infrared light R1 is absorbed by the veins, only images in a certain depth (sharpness) interval are taken as the vein brightness interval images. The first brightness interval image and the second brightness interval image defined by the vein brightness interval image higher or lower may be hard bone tissue, connective tissue, adipose tissue, cartilage tissue or other tissue cells, etc., which are not included in the present invention. limit.

Therefore, the display 500 of this embodiment is disposed on the stand 100 and is electrically connected to the first receiver 400a. And the display 500 displays the vein image V converted from the infrared light image R2a. More specifically, the vein image V is an image formed by the aforementioned image conversion of the vein brightness interval, which clearly shows the position of the vein.

In this embodiment, the transmitter 200 further includes a lens 201 . The lens 201 is in close contact with the illuminated portion H. In the present invention, the term "closeness" does not only refer to closeness, but also includes meanings such as closeness and closeness of actual physical contact, which all belong to the definition category of the present invention.

In this embodiment, the lens 201 is a fish-eye lens, and further can be a fish-eye lens group. The purpose is to allow the infrared light R1 emitted by the transmitter 200 to freely control its emission direction. And according to the position of the illuminated part H and the first receiver 400a, the light-emitting direction of the infrared light R1 is adjusted. Therefore, through the above technical means, it is easier to achieve the requirement that the first receiver 400a, the illuminated portion H and the transmitter 200 must be located on the same line in this embodiment.

In other words, the transmitter 200 substantially includes the function of tracking the position of the illuminated portion H in an omnidirectional manner. Therefore, the position of the first receiver 400a must be adjusted by other means to meet the definition of being on the same straight line.
