  • Patent number: 11719232
    Abstract: A driving system for driving piezoelectric pump includes one or more mechanical devices and a driving circuit system electrically connected to the at least one mechanical device. The driving circuit system includes a pump-driving unit, a linear voltage-stabilizing unit, a microcontroller unit, a current-sensing unit, and a connection unit. The microcontroller unit generates a first signal, a second signal, and a third signal, and the pump-driving unit receives these signals to drive the mechanical device. The current-sensing unit receives a fourth signal transmitted by the pump-driving unit to obtain an actuation current value of the mechanical device. The linear voltage-stabilizing unit, the current-sensing unit, and the microcontroller unit are coupled to each other through a fifth signal and a sixth signal. The connection unit and the microcontroller unit are coupled to each other through a reset signal, a seventh signal, and an eighth signal provided by the microcontroller unit.

  • Patent number: 9795677
    Abstract: The present invention features a method for reducing the damage caused by free radicals, the method comprises administering a pharmaceutical composition that comprises at least a metal or its ions, at least a drug or an antioxidant that is carrier-protected/modified, and a drug carrier to a subject. Said carrier helps to preserve the anti-oxidative activity, and hence, prevents the decrease of the effect of the antioxidant against free radicals produced in the environment or body fluids and prolongs protection, and be used for reducing damage caused by radiation and adverse effects induced by chemotherapeutic drugs.

  • Patent number: 9597406
    Abstract: This invention provides the controlled-release method for a pharmaceutical composition comprising of metals in the drug carrier. The specific chelator is used to trigger the release of active pharmaceutical ingredients from chelating complex micelles. The drug release rate and half-life can also be controlled by manipulating the dosing sequence and the concentration of metal and specific chelator.

  • Patent number: 9226967
    Abstract: This invention provides Chelating Complex Micelles as a drug carrier. The Chelating Complex Micelles can load drugs without changing their structure, and therefore extend the half-life of drugs in the human body. The chelating complex micelles contain a metal ion core, at least one polymer, and at least one drug molecule. The metal ion is considered as a Lewis acid while polymer chain and drug molecules are referred to as Lewis bases. The drug molecule is linked to the polymer via forming coordinate bonds with metal ion, and then self-assembled to form chelating complex micelles as a drug carrier.
