Vein Pattern Locating Technology for Cannulation: A Review of the Low-Cost Vein Finder Prototypes Utilizing near Infrared (NIR) Light to Improve Peripheral Subcutaneous Vein Selection for Phlebotomy <s> Site for venipuncture <s> Introduction. This study aims to evaluate for the first time the value of visualizing veins by a prototype of a near-infrared (NIR) vascular imaging system for venipuncture in children. Methods. An observational feasibility study of venipunctures in children (0-6 years) attending the clinical laboratory of a pediatric university hospital during a period of 2 months without (n = 80) and subsequently during a period of 1 month with a prototype of an NIR vascular imaging system (n = 45) was conducted. Failure rate (ie, more than 1 puncture) and time of needle manipulation were determined. Results. With the NIR vascular imaging system, failure rate decreased from 10/80 to 1/45 (P = .05) and time decreased from 2 seconds (1-10) to 1 second (1-4, P = .07). Conclusion . This study showed promising results on the value of an NIR vascular imaging system in facilitating venipunctures. <s> BIB001 </s> Vein Pattern Locating Technology for Cannulation: A Review of the Low-Cost Vein Finder Prototypes Utilizing near Infrared (NIR) Light to Improve Peripheral Subcutaneous Vein Selection for Phlebotomy <s> Site for venipuncture <s> Venipuncture is pivotal to a wide range of clinical interventions and is consequently the leading cause of medical injury in the U.S. Complications associated with venipuncture are exacerbated in difficult settings, where the rate of success depends heavily on the patient's physiology and the practitioner's experience. In this paper, we describe a device that improves the accuracy and safety of the procedure by autonomously establishing a peripheral line for blood draws and IV's. The device combines a near-infrared imaging system, computer vision software, and a robotically driven needle within a portable shell. The device operates by imaging and mapping in real-time the 3D spatial coordinates of subcutaneous veins in order to direct the needle into a designated vein. We demonstrate proof of concept by assessing imaging performance in humans and cannulation accuracy on an advanced phlebotomy training model. <s> BIB002 </s> Vein Pattern Locating Technology for Cannulation: A Review of the Low-Cost Vein Finder Prototypes Utilizing near Infrared (NIR) Light to Improve Peripheral Subcutaneous Vein Selection for Phlebotomy <s> Site for venipuncture <s> This work presents a portable, affordable and reliable vein locating device to overcome the complications in vein localization irrespective of age and tissue thickness during medical procedures like Phlebotomy and intravenous infusion. A prototype has been developed using infrared (IR) detector and multispectral near infrared (NIR) (740,765,770,780 nm) source. The differential absorption of the NIR by veins due to the presence of deoxyhemoglobin, helps in enhancing the localization of the vein. The detector is integrated with the single board computer (SBC) and connected with LCD through serial programming interface (SPI) for real time display of veins. The initial observations have found to be successful. It is expected that this affordable device will help in reducing time and improving accessibility to locate antecubital and cephalic vein without multiple incision and minimal pain. <s> BIB003 </s> Vein Pattern Locating Technology for Cannulation: A Review of the Low-Cost Vein Finder Prototypes Utilizing near Infrared (NIR) Light to Improve Peripheral Subcutaneous Vein Selection for Phlebotomy <s> Site for venipuncture <s> OBJECTIVE ::: To compare the performance on the detection of the invisible veins between our modified prototype device and an existing device in elderly hospitalized patients. ::: ::: ::: METHODS ::: A prospective, cross-sectional, and observational study was performed in the invisible veins in elderly patients. The major variables, skin color near the invisible veins, and diameter and depth of the invisible veins were measured. The vein visualization rate was calculated as the ratio of the visualized veins to the invisible veins by the visualization device. ::: ::: ::: RESULTS ::: We analyzed 53 invisible veins in the cubital fossa and 56 invisible veins in the forearm in a total of 72 patients (median age, 73 years). The visualization rate for our prototype device was higher than that for an existing device in the cubital fossa and the forearm sites. The visualized veins of the prototype device had a higher intensity ratio than that of an existing device. No significant differences were observed in the body mass index, vein depth, and vein diameter of the visualized veins at the cubital fossa and forearm sites. ::: ::: ::: CONCLUSION ::: The prototype surpassed the existing device in visualizing the invisible veins. However, the prototype was unable to visualize all the invisible veins. We need to look for ways to reduce noise and to visualize the invisible veins, and the visualization rate of devices needs to be investigated in further association with the percentage of success with actual intravenous access and locating time to vein. <s> BIB004 </s> Vein Pattern Locating Technology for Cannulation: A Review of the Low-Cost Vein Finder Prototypes Utilizing near Infrared (NIR) Light to Improve Peripheral Subcutaneous Vein Selection for Phlebotomy <s> Site for venipuncture <s> Detection of intra vena is very important technique in the medical clinic applications. For intravenous detection, some nurses usually have a mistake which can cause a pain or injured to the patient. When the nurses are headed with this problem, it becomes dangerous for the patient. To solve the problem, in this paper, vein finder with multi-tuning wavelength for intra vena detection is proposed and investigated. Vein finder is tested to various skin colour and body mass. The results show that vein finder was successfully designed with controllable wavelength in the range of 600-696 nm using RGB LED. <s> BIB005 </s> Vein Pattern Locating Technology for Cannulation: A Review of the Low-Cost Vein Finder Prototypes Utilizing near Infrared (NIR) Light to Improve Peripheral Subcutaneous Vein Selection for Phlebotomy <s> Site for venipuncture <s> Poor quality of the images captured by a conventional vein viewer or finder renders it to be un-useful as a diagnostic tool. This is a result of an insufficient amount of venous blood in the superficial veins and the low resolution of the near-infrared (NIR) cameras used in the traditional vein viewers. In this paper, we propose using a high resolution NIR camera, vein warmer and image contrast enhancer (CLAHE) to improve the view of the superficial veins. This approach effectively produces a diagnostic medical superficial vein images. <s> BIB006
The preferred venipuncture sites include the antecubital fossa and the back of the hand that has the superficial vein. Veins are blood vessels that aim to return the blood to the heart. It has a higher percentage of deoxygenated blood (deoxyhemoglobin) as compared to arteries that have higher level of oxygenated blood (oxyhemoglobin) BIB006 . Hemoglobin (Hb) is the primary component of the blood, specifically; of the red blood cells that have the oxygen carrying capacity  . There are three veins that can be selected. Among the three are the veins in the median aspect (center of the arm) must be the first choice followed by the veins in the lateral aspect (outer thumb side), i.e., the cephalic vein, and last are the veins in the medial aspect (inner little finger side), i.e., the basilic vein  . Figure 5 shows the main veins of the antecubital fossa (a) median cubital vein, (b) cephalic vein, and (c) the basilic vein. The median cubital vein is considered as the best site for venipuncture. It lies over the cubital fossa and serves as a branching between the cephalic and basilic veins  . Compared to the two other sites it is well anchored vein, usually large and prominent  . Age as a factor to be considered was clearly described by Dhakshayani M and Yacin S., 2015 BIB003 in their study. In the elderly, vein access was challenging due to the changes in the vein structure as thin and fragile people lose elasticity while pediatrics have smaller peripheral veins with higher content of subcutaneous fat and are usually prone to vasoconstriction. This parameter was also considered in different studies BIB001 BIB005 BIB004 BIB002 .
