摘要： A flow meter, and related method, include a coupler adapted to couple to a drip chamber, a support member operatively coupled to the coupler, an image sensor and a backlight. The image sensor has a field of view and is operatively coupled to the support member. The backlight is adapted to illuminate the image sensor to expose the image sensor such that the field of view of the image sensor at least partially images at least a portion of the drip chamber. A processor receives image data from the image sensor to select a region of interest of the image sensor, determine whether a pixel of the image sensor is within the region of interest, activate the at least one light of the backlight when the pixel of the image sensor is within the region of interest, and expose the pixel of the image sensor.

摘要： A method of preparing a pharmaceutical product in a single multiple chamber flexible bag. A pharmaceutical product is introduced in a liquid state into a first chamber of the flexible bag through a first port. The pharmaceutical product is lyophilized within the first chamber of the flexible bag to provide a lyophilized pharmaceutical product. The flexible bag has a second chamber and the first chamber and the second chamber are separated by a breakable seal. The second chamber further includes a reconstituting solution for reconstituting the lyophilized pharmaceutical product in the first chamber. A user may apply pressure to the flexible bag to break the seal and mix the lyophilized pharmaceutical product and the reconstituting solution to order to administer the pharmaceutical product to a patient.

摘要： A droplet measurement system is provided with: an imaging device placed to locate a tip part of a nozzle and the entire liquid hanging down from the nozzle within a field of view; an image generation unit that generates a plurality of images that capture the state in which droplets are dripping down from the nozzle based on image data output from the imaging device; a dripping detection unit that detects, from the plurality of images, a dripping-detected image in which the fact that a droplet has departed from the nozzle is detected; and a volume calculation unit that calculates the volume of the droplet based, at least, on an image-before-dripping, which is generated a predetermined number of frames before the dripping-detected image and capturing liquid hanging down from the nozzle and on a reference image that captures at least the tip part of the nozzle.

摘要： A flow meter includes a background pattern disposed behind a drip chamber, an image sensor, and a processor. The image sensor has a field of view and is configured to view the drip chamber within the field of view. The processor is coupled to the image sensor to receive image data therefrom and captures, using the image sensor, an image of the drip chamber and at least a portion of the background pattern, examines the image, and adjusts a flow rate of fluid flowing through a fluid line in accordance with the examination of the image.

摘要： A portable electronic fluid dispensing system can provide pre-filled, pre-primed IV bag assemblies comprising therapeutic fluids. The same fluid line and connector in the IV bag assembly can be used to fill the IV bag as is used to withdraw fluid from the IV bag and infuse such fluid into the patient. The connection points along the IV assembly, such as the connection between the IV bag and a drip chamber, or between an IV bag and tubing, or between a drip chamber and tubing, or between tubing and a closeable, resealable connector, can each be resistant to disconnection by a user. The healthcare practitioner at the patient care site is not required to attach any of these components to each other, and the healthcare practitioner at the patient care site is not required to introduce a spike into a spike port on the IV bag.
