ICU Medical has been granted a patent for an infusion pump that can reject false touch inputs. The pump includes a touchscreen display, a processor, and a memory. The processor executes a false touch rejection process by determining if the touchscreen input corresponds to a false touch, based on contact parameters such as the shape of the contact. This technology aims to improve the accuracy and reliability of infusion pumps. GlobalData’s report on ICU Medical gives a 360-degree view of the company including its patenting strategy.

Infusion pump rejecting false touch input
A recently granted patent (Publication Number: US11775166B2) describes an infusion pump with a touchscreen display that is capable of rejecting false touch inputs. The infusion pump includes a touchscreen display that can display information related to the pump and receive touchscreen inputs. The pump also includes a processor and memory that store instructions for executing a false touch rejection process.
The false touch rejection process works by receiving a touchscreen input corresponding to a contact with the touchscreen display. The process then determines a contact parameter, such as the shape of the contact, from the touchscreen input. If the shape of the contact corresponds to the shape of a tubing segment, indicating a false touch, the touchscreen input is rejected.
The touchscreen display of the infusion pump can receive touchscreen inputs by sensing a change to an electromagnetic field or a change in capacitance. The processor can determine the contact parameter by determining the position or movement of the contact corresponding to the touchscreen input.
The false touch rejection process includes various criteria for determining if a touchscreen input is a false touch. For example, it can determine that a touchscreen input corresponds to a false touch if the position of the contact moves in a downward direction, if the volume of the contact increases over time, or if the width of the contact remains constant while the height increases over time.
The patent also describes a method for rejecting false touch inputs to a touchscreen display of a medical device. The method includes receiving a touchscreen input, determining the contact parameter, and determining if the shape of the contact corresponds to a tubing segment, indicating a false touch.
Overall, this patent describes an infusion pump with a touchscreen display that is equipped with a false touch rejection process. This technology can help prevent accidental inputs and improve the accuracy and reliability of the infusion pump.
