CONNECTION OF A STOPPER AND PISTON IN A FLUID DELIVERY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240017022 titled 'CONNECTION OF A STOPPER AND PISTON IN A FLUID DELIVERY DEVICE

Simplified Explanation

The abstract describes a device for delivering fluid to a user. The device includes a fluid reservoir with an internal volume and a stopper with a cavity positioned within the reservoir. A piston is received within the cavity of the stopper, and an actuator is coupled to the piston to drive it into the reservoir. A coupling device engages the piston in the cavity at a desired position, and a sensor determines if the piston is engaged at the desired position.

  • The device is designed to deliver fluid to a user.
  • It includes a fluid reservoir for holding the fluid.
  • The reservoir has an internal volume.
  • A stopper is positioned within the reservoir and has a cavity.
  • A piston is received within the cavity of the stopper.
  • An actuator is used to drive the piston into the reservoir.
  • A coupling device ensures the piston is engaged in the cavity at a desired position.
  • A sensor determines if the piston is engaged at the desired position.

Potential applications of this technology:

  • Medical devices for delivering medication or fluids to patients.
  • Industrial applications for precise fluid delivery in manufacturing processes.
  • Consumer products such as nasal sprays or eye droppers.

Problems solved by this technology:

  • Ensures accurate and controlled delivery of fluids.
  • Prevents leakage or spillage during fluid delivery.
  • Allows for precise dosing of medication or fluids.

Benefits of this technology:

  • Improved accuracy and precision in fluid delivery.
  • Enhanced user experience with controlled and reliable delivery.
  • Reduces waste and potential errors in fluid administration.


Original Abstract Submitted

a device for delivering fluid to a user includes a fluid reservoir for holding the fluid, the fluid reservoir defining an internal volume and a stopper positioned in the internal volume of the fluid reservoir, wherein the stopper is formed with a cavity. the device further includes a piston having a distal end received within the cavity of the stopper and an actuator coupled to the piston for driving the piston into the internal volume of the fluid reservoir. also, the device includes a coupling device for engaging the piston in the cavity of the stopper at a desired position and a sensor for determining whether the piston is engaged in the cavity of the stopper at the desired position.
