The main value of the venous imaging device in oncology departments and chemotherapy wards lies in addressing the "difficult needle insertion" problem faced by chemotherapy patients due to repeated punctures and deteriorating vascular conditions. It not only significantly improves the success rate of the first puncture, shortens the operation time, but also reduces the pain experience of patients during the puncture process and enhances their satisfaction with medical treatment.

Clinical research data have demonstrated its specific effects:

Improving the success rate of one-time puncture: When using an infrared imaging device on elderly cancer patients, the success rate of one-time puncture can increase from 73.6% in the control group to 92.5%. Recent randomized controlled trials also show that using a near-infrared light imaging device results in significantly higher scores for the visibility of blood vessels reported by nurses.

Shortening the operation time: The use of the imaging device significantly reduces the total time required to locate the blood vessels and successfully perform the puncture. Studies have shown that the puncture time in the group using the equipment is significantly faster than that in the manual group.

Enhancing patient and nurse satisfaction: Successful punctures directly reduce patients' pain and anxiety. Research has confirmed that patients using the imaging device have higher satisfaction with the nursing procedures, and the puncture confidence of the nurses has also significantly increased.

These advantages mainly stem from the specific clinical needs of cancer patients:

"Chemotherapy-induced phlebitis" and vascular sclerosis: Repeated damage to the vascular endothelium caused by long-term infusion of chemotherapy drugs leads to hardening, brittleness, and collapse of the veins, making the traditional puncture method relying on vision and touch extremely difficult. The imaging device can penetrate the skin and clearly display the direction and bifurcations of the blood vessels, helping nurses avoid unhealthy vascular segments.

Protecting limited venous resources: Chemotherapy patients usually require long-term treatment, and every available vein is extremely precious. Using the imaging device to reduce the number of puncture failures can maximize the avoidance of vein damage and extend the lifespan of the patient's venous vessels, preserving the access for subsequent treatments.
Applicable to elderly and special patients: Elderly cancer patients have loose skin, reduced subcutaneous fat, poor vascular elasticity, and prone to sliding. Studies have specifically confirmed that the infrared venous imaging device has a significant effect in elderly cancer patients, effectively solving these problems.

Expansion of Applications and Limitations

Apart from the conventional peripheral venous puncture, the venous imaging technology can also assist in more complex surgical procedures. For instance, a study utilized the dynamic ultrasound imaging technique to perform PICC (peripherally inserted central catheter) catheterization for cancer patients in the ICU, and was able to provide real-time guidance for addressing catheter malposition issues.
