Abstract: There is described a method of filtering a captured image of a drip chamber configured to allow a drop of fluid to fall within the drip chamber, the method comprising: capturing an image of the drip chamber with an image sensor; determining if the captured image contains a visual obstruction; applying a blurring function to the captured image, the blurring function configured to eliminate an amount of detail in the captured image; and determining if the captured image contains a match to a template. There is also described an apparatus comprising: an image sensor configured to capture an image of a drip chamber; and a processor operatively coupled to the image sensor, the processor being configured to: determine if the captured image contains a visual obstruction; apply a blurring function to the captured image, the blurring function configured to eliminate an amount of detail in the captured image; and determine if the captured image contains a match to a template.

Abstract: A peristaltic pump is disclosed. The peristaltic pump comprises a plunger configured to engage with a tube; a spring configured to bias the plunger against the tube; a position sensor operatively coupled to the plunger; an inlet valve configured to impede fluid flow through the tube positioned upstream of the plunger; an outlet valve configured to impede fluid flow through the tube positioned downstream of the plunger; and at least one processor in operative communication with the position sensor. The position sensor is configured to determine a position of the plunger. The at least one processor is configured to monitor the position of the plunger when the inlet and outlet valves are closed and the plunger is being biased by the spring, and determine at least one of an occlusion, an air bubble, and a leak exists in accordance with the monitored position of the plunger.

Abstract: A method for estimating volume of drop in intravenous drip chamber using pixels contained in the drop’s outline is described. The method determines a relevant subset of pixels in the image of the drop in the drip chamber by assessing which pixels represent the edge of the drop and whether the edge of the drop is contiguous with a baseline (215) determined within the drip chamber. The pixels within the outline are counted to indicate the area in the image, and the area is rotated and thus integrated to determine the volume.

Abstract: An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube. 18722089_1 (GHMatters) P101057.AU.3
