MFTH Patent Number: 7,347,841 for a technology for a medical assembly and a protector, or locking mechanism, that is intended to ensure that no substances can be released from the hypodermic needle without positive pre-matching between the substance and the specific patient.

Here is the abstract of MFTH`s patent: A medicine assembly, and a protector that fits over at least a portion of the medicine assembly, the protector including a bar code and a locking element openable by means of a bar code reader reading the bar code, wherein when the locking element is in a locked orientation, the protector substantially prevents administration of a substance from the medicine assembly.

MFTH`s invention, based on the patent, is a medical assembly which may effectively prevent unauthorized administration of a drug or medicinal substance by hypodermic needle. It accomplishes this by taking a medical assembly and incorporating a locking mechanism that is intended to ensure the substance cannot be released from the hypodermic needle without positive pre-matching between the substance and the specific patient, identified by bar-coding or other identification technology.
