The apparatus also includes a processing unit configured to receive data representing the portion of the detected electromagnetic radiation from each of the plurality of sensors. The processing unit is further operable to convert the received data into a signature representative of the electromagnetic radiation detected by the plurality of sensors.

An infusion set of a system for detecting and controlling drip rate is disclosed. The infusion set includes an infusion device and an adjustment device. The adjustment device is installed on the infusion device and for adjusting drip rate of injection in the infusion device. The infusion set of the system further includes an activating unit and at least one detecting module. The activating unit is coupled to a control unit of the system for providing staff in the hospital to control the drip rate through operation of the control unit. Further, the infusion set of the system further includes further includes at least one detecting module for drip counts, whereby it provides the staff with further information when controlling the drip rate of the infusion set.

A flow meter, and related system and method are provided. The flow meter includes a coupler, a support member, an image sensor, a valve, and one or more processors. The coupler is adapted to couple to a drip chamber. The support member is operatively coupled to the coupler. The image sensor has a field of view and is operatively coupled to the support member. The image sensor is positioned to view the drip chamber within the field of view. The one or more processors are operatively coupled to the image sensor to receive image data therefrom and to the actuator to actuate the valve. The one or more processors are configured to estimate a flow of fluid through the drip chamber and to actuate the valve to control the flow of fluid through the drip chamber to achieve a target flow rate.

An infusion apparatus includes a housing and a chamber configured to be connected to the housing. The apparatus further includes a weight sensor coupled to a load connector connected to the housing and an optical sensor disposed in the housing. The weight sensor is configured to generate a first signal based on a measured weight of the fluid container attached to the housing in a weight-bearing configuration. The optical sensor is configured to generate a second signal based on detecting drops of the fluid traversing the chamber. The apparatus also includes a flow control mechanism to control a flow rate of the fluid into an outlet channel. The apparatus includes one or more processing devices configured to perform operations including transmitting a control signal to the flow control mechanism to adjust the flow rate.

An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

The present disclosure relates to a urine monitoring method adapted to a urine monitoring device and a cloud server. The urine monitoring method includes the urine monitoring device detecting a real-time weight, the urine monitoring device sending the real-time weight to the cloud server through a communication interface, and the cloud server determining whether the real-time weight is less than a lower bound of a current weight or is greater than an upper bound of the current weight. If the real-time weight is either less than the lower bound of the current weight or greater than the upper bound of the current weight, the cloud server sends a signal to set the urine monitoring device as a urine volume warning status.

Devices, systems, and associated methods for detecting drops dispensed by a dropper are provided. For example, a drop detection device may include a light source and a light detector configured to be coupled to a drop dispenser such that the light source and light detector are disposed proximal of a distal dispensing tip of the drop dispenser. The light detector may be configured to receive a reflected portion of a beam of light from the light source, which is reflected by a drop dispensed through the dispensing tip of the drop dispenser. In some embodiments, a processing circuit is configured to analyze a signal provided by the light detector to detect the dispensed drop.

A method of operating an infusion pump includes transmitting light through or around a drop of fluid suspended from an end of a drip tube for the infusion pump, the end of the drip tube located in a drip chamber for the infusion pump, wherein the drip tube is configured for connection to a source of the fluid; receiving, using an optical system for the pump, light transmitted through or around the drop; transmitting, to a specially programmed microprocessor and using the optical system, data regarding the received light; and, using the microprocessor to calculate a volume of the drop using the data.
