The neurology consultant’s patented syringe can be used without a pump barrel attached to a traditional stainless steel needle that sometimes ruptures blood veins, causing patients significant pain and at times leading to infectious diseases.
In Dr. Al-Rasheed’s process, a pointy-end component made of carbon fiber, plastic, silicon, cellulose or fiberglass is attached to the pump. The tip is covered with a soluble paint that dissolves when it gently penetrates the skin.
The non-metal end can penetrate smaller veins, decreasing the time to find an appropriate point of penetration and reducing the risk of infectious diseases and failed procedures.
In addition to the patient, Supervisor of Intellectual Property and Technology Licensing Program (IPTL) Dr. Khalid Al-Saleh said that medical personnel, occasionally pricked by the metal tip during injections, are accorded a sense of ease and safety by the new syringe end.
Dr. Al-Rasheed’s invention, patent No. 8382740, is titled “Trocar Less Intravenous Cannula with a Multifilament Tip.”
The first hypodermic metal needle fine enough to penetrate the skin was developed in 1853, and the process has undergone only subtle modifications since then.
Other technologies to replace IV needles are currently in the works, including a micro-needle patch of 400 silicon-based microscopic needles under development at Georgia Institue of Technology in the U.S.
