DEVICE ASSEMBLY FOR NEEDLELESS SYRINGE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240017011 titled 'DEVICE ASSEMBLY FOR NEEDLELESS SYRINGE
Simplified Explanation
The abstract describes a device assembly for a needleless injector that includes a gas generating agent with a slower combustion rate and longer combustion duration than an ignition agent. The device assembly is designed to pressurize the injection objective substance, causing the ejection pressure to increase to a first peak pressure, decrease, and then increase again to a second peak pressure. An igniter is activated to reach the first peak pressure using the combustion gas pressure of the ignition agent.
- The device assembly includes a gas generating agent with a slower combustion rate and longer combustion duration than an ignition agent.
- The injection objective substance is pressurized, resulting in an ejection pressure that increases to a first peak pressure, decreases, and then increases again to a second peak pressure.
- An igniter is activated to reach the first peak pressure using the combustion gas pressure of the ignition agent.
Potential Applications:
- Needleless injection systems in medical and healthcare settings.
- Delivery of medication or vaccines without the use of needles.
- Industrial applications where precise and controlled substance ejection is required.
Problems Solved:
- Eliminates the need for needles in injection procedures, reducing the risk of needlestick injuries and associated infections.
- Provides a controlled and precise ejection of substances without the use of needles.
- Offers a safer and more convenient alternative to traditional injection methods.
Benefits:
- Reduces the risk of needlestick injuries and associated infections for healthcare professionals and patients.
- Provides a painless and needle-free injection experience for patients.
- Allows for precise and controlled delivery of substances.
- Offers a more convenient and accessible method for administering medication or vaccines.
Original Abstract Submitted
a device assembly for a needleless injector including a gas generating agent formed such that a combustion rate thereof is lower than a combustion rate of an ignition agent and a combustion duration thereof is longer than a combustion duration of the ignition agent. the device assembly may be configured to pressurize the injection objective substance such that an ejection pressure of the injection objective substance, defined as a pressure of the injection objective substance ejected from an ejection port, increases to a first peak pressure after pressurization is started, decreases to a pressure lower than the first peak pressure, and then increases again to a second peak pressure. the device assembly may be configured to activate an igniter and cause the ejection pressure of the injection objective substance to reach the first peak pressure by a pressure of a combustion gas of the ignition agent.
