Painless Injection System
Background
- Conventional medical devices for injecting medications into the muscles and tissues of a patient are typically some form of a manual hypodermic syringe system.Receiving an injection by such a conventional device can be a very traumatic experience for many patients, particularly a child.
- These fears are primarily caused by pain associated with hypodermic syringe injections.
- The child's fear, and that of his/her parents, becomes a significant medical problem if it leads to a child not receiving a required immunization and other therapeutic medications.
- Studies have shown a close relationship exists between the pain associated with injections and the size of the needle and the flow rate at which medications are injected.
- Large diameter needles cause more pain and discomfort, while excessively high injection rates can tear away tissue and cause excessive build-up of fluid pressure around muscle and other structures.
- In addition, once a patient experiences these discomforts, the sight of a hypodermic needle by itself often triggers tension, anxiety and rejections, increasing the difficulty for the deliverer of needed medications and immunizations and, in some cases, threatening the safety of those involved.
- Recent attempts to address this problem by administering either a topical or injected anesthetic have not always resolved these issues.
- These approaches may not always be desirable for a patient and may add unnecessary expense to the total procedure.
Description of Current Technology
The present invention, developed in the laboratory of Dr. Eric Wall, provides a substantially painless method and an apparatus for injecting medications into a patient. Specifically, this technology utilizes a device that houses a quantity of medication and a fine gauge hypodermic needle out of sight of the patient. The device is attached to the patient and when activated, delivers the medication at a rate of injection effective for absorption into the tissue without causing pain. Preliminary tests using fine needles and slow injection rates in human subjects markedly reduced the discomfort associated with the procedure and, in most cases, no discomfort or pain was reported. Some subjects were actually unaware that an injection had been administered. A formal study in pediatric patients is being initiated. A patent application has been filed and a working prototype is being pursued.
Objective
The Cincinnati Children's Research Foundation (CCRF) is seeking a corporate partner for the development, testing and commercialization of this painless injection technology. CCRF is prepared to enter into an option or license agreement and/or to conduct further corporate sponsored research to provide proof of concept data.
