Description

Venous Detection Projector Apparatus}

The present invention relates to a vein detection projector device. More specifically, it assists in finding veins more easily when administering an intravenous injection at a medical institution, and is linked to the Hospital Information System (HIS) when prescribing an injection. This relates to a vein detection projector device that enables transmission and reception of necessary data.

Intravenous injections performed in hospitals are generally a field that requires such skilled skills that they can only be performed by separately hired professional nurses, but recently, as the social shortage of nurses continues, it is difficult to secure nurses skilled in intravenous injections. This situation is becoming increasingly difficult.

The vascular scanning device designed to solve this problem was developed to solve the shortage of nurses and to provide smooth injections to subjects such as dark-skinned blacks, infants whose blood vessels are difficult to detect, the elderly, and obese patients. A market worth $29.26 billion has been created.

However, such conventional blood vessel scanning devices only provide the function of finding blood vessels, so their utilization is low.

Currently, the risk of medical accidents is increasing due to the expansion of nurses' work areas, and the intensity of nursing work has recently increased extremely due to the international pandemic, making it more convenient than existing blood vessel scanning devices. There is a need for an equipped device.

Therefore, a method to solve these problems is required.
