  "patent_number": "US 12734300",
  "country": "US",
  "title": "Precise Medicine Delivery Device with Priming Control",
  "original_title": "Devices and methods for precision dose delivery",
  "summary": "This patent describes a device for accurately measuring and delivering liquid medicine, using a special mechanism to control how a plunger moves during both initial setup and actual delivery.",
  "what_it_does": "This device is designed to deliver a specific amount of liquid medicine or other fluid with high accuracy. It includes a main body that holds the liquid, and a plunger rod that pushes a stopper inside the body. The key feature is a special component that precisely controls the forward movement (distal movement) of the plunger rod. This control happens during two distinct phases: a 'priming step' to prepare the device, and a 'subsequent delivery step' to dispense the medicine. This two-step regulation ensures that the device is accurately prepared and then delivers the exact predetermined volume. For example, an insulin pen could use this technology to ensure each dose is consistently accurate, reducing the risk of under- or over-dosing.",
  "what_it_does_not_cover": [
    "Does not cover devices that deliver medicine as a continuous drip without distinct priming and delivery steps controlled by a plunger.",
    "Does not cover devices where the dose is determined by factors other than the controlled distal movement of a plunger rod pushing a stopper.",
    "Does not cover devices that lack a specific component designed to regulate the plunger rod's movement during both a priming step and a delivery step.",
    "Does not cover drug delivery systems that rely on gravity, pumps, or other mechanisms without a physical plunger rod and stopper for dispensing.",
    "Does not cover devices where the 'predetermined volume' is not achieved through the precise regulation of plunger rod movement."

  "abstract": "Disclosed herein are devices and methods for delivering a predetermined volume of a drug substance or other product including a fluid. An exemplary device may include a body configured to receive a drug substance therein, and a plunger rod disposed at least partially inside the body to distally move a stopper in the body. The device may include a component configured to regulate distal movement of the plunger rod in a priming step and in a subsequent delivery step, so that the device may be accurately primed and may accurately dispense a predetermined volume of a drug substance.",
