Device for measuring liquid volume expelled from syringe
A recently granted patent (Publication Number: US12013267B2) discloses a novel device designed to measure the volume of liquid expelled from a syringe barrel accurately. The device comprises a syringe barrel with a plunger and a sensor having two ports, one in fluid communication with the syringe barrel and the other with an external fluid source. The sensor operates by detecting pressure differentials through the second port connected to the external fluid source, allowing for precise volume measurements of liquid expelled from the syringe barrel. Additionally, a controller connected to the sensor records these pressure readings, enabling the calculation of the total volume of liquid expelled from the syringe barrel.
Furthermore, the patent details a method for measuring the liquid volume expelled from the device, involving sliding the plunger to expel liquid through a liquid orifice, detecting pressure differentials over time, and calculating the volume of liquid expelled based on the recorded pressure data. The device also includes a hollow plunger rod with a sensor housed within a thumb pad, enhancing user convenience during operation. With applications in various fields requiring accurate liquid measurements, such as healthcare for administering precise doses of therapeutic agents, this patented device offers a reliable and efficient solution for measuring liquid volumes with precision and ease.
