摘要： A sensor apparatus and sensor apparatus system for use in conjunction with a cassette (2300), including a disposable or replaceable cassette. In some embodiments, the cassette includes a thermal well (5100) for permitting the sensing of various properties of a subject media. The thermal well includes a hollow housing of a thermally conductive material. In other embodiments, the cassette includes sensor leads for sensing of various properties of a subject media in a fluid line (2303). The thermal well has an inner surface shaped so as to form a mating relationship with a sensing probe (6000). The mating thermally couples the inner surface with a sensing probe. In some embodiments, the thermal well is located on a disposable portion and the sensing probe on a reusable portion.

摘要： An apparatus, comprising: a coupler adapted to couple to a drip chamber; a support member operatively coupled to the coupler; and an image sensor having a field of view and operatively coupled to the support member, wherein the image sensor is configured to view the drip chamber within the field of view; at least one processor operatively coupled to the image sensor to receive image data therefrom, wherein the at least one processor is configured to: capture a first image; create a first thresholded image from the first image by comparing each pixel of the first image to a threshold value; determine a set of pixels within the first thresholded image connected to a predetermined set of pixels within the first thresholded image; filter all remaining pixels of the first thresholded image that are not with the set of pixels, the filter operates on a pixel-by-pixel basis within the time domain to generate a first filtered image; remove pixels determined to not be part of a drop from the first thresholded image using the first filtered image to generate a second image; determine a second set of pixels within the second image connected to a predetermined set of pixels within the second image to generate a third image, the third image identifies the second set of pixels within the second image; determine a first length of the drop by counting the number of rows containing pixels corresponding to the second set of pixels within the third image, the first length corresponding to a first estimated drop size; update a background image using the first image; create a second thresholded image by comparing first image with background image; sum the rows of second thresholded to create a plurality of row sums, each row sum corresponds to a row of the second thresholded image; start at a row position of the second thresholded image having a first sum of the plurality of sums that corresponds to the first length; increment the row position until the row position corresponds to a corresponding row sum that is zero; determine a second length is equal to the present row position, the second length corresponding to a second estimated drop size; and average the first and second lengths to determine a average length, the average length corresponding to a third estimated drop size.

摘要： The disclosure of this specification relates to many aspects of a haemodialytic system. This includes a drainage system, blood circuit, pumps and routing channels, occlusion assemblies, ability to be portable, modular components and dialysis unit. In particular, an improved occlusion assembly as part of an infusion device is claimed. This assembly may have a pair of collapsible tubes with a spreader positioned between the tubes. The spreader is able to increase the size of the space between the two tubes. The spreader may have an actuator to control its movement and the changes in occlusion. The collapsible tubes may cause occlusion in absence of an outside force. A method using this assembly is also disclosed.

摘要： Abstract Hemodialysis dialysis systems are disclosed. Hemodialysis systems of the invention may include a dialysate flow path including a balancing circuit, a mixing circuit, and/or a directing circuit. The circuits may be defined within one or more cassettes. The fluid circuits may be at least partially isolated, spatially and/or thermally, from electrical components of the system. A gas supply may be provided in fluid communication with the dialysate flow path and/or the dialyzer to urge dialysate through the dialyzer and blood back to the patient. The hemodialysis systems may include fluid handling devices, actuated using a control fluid, optionally delivered using a detachable pump. Fluid handling devices may be generally rigid and of a spheroid shape, optionally with a diaphragm dividing the device into compartments.
