    Abstract: Se describen mejoras en los sistemas de medición de volumen de fluido para una bomba de diafragma activada neumáticamente en general, y un ciclador de diálisis peritoneal que utiliza un casete de bomba en particular; las mediciones de volumen del fluido de la bomba se basan en las mediciones de presión en una cámara de control de la bomba y una cámara de referencia en un modelo de dos cámaras, con diferentes secciones del aparato estando diseñadas usando una combinación de procesos adiabáticos, isotérmicos y politrópicos; también se describen mediciones de flujo en tiempo real o instantáneas en una cámara de bomba de una bomba de diafragma, en este caso usando un modelo de gas ideal de una cámara y usando un procesador de alta velocidad para obtener y procesar las presiones de la cámara de control de la bomba durante el flujo de fluido hacia adentro o hacia afuera de la cámara de bomba; también se describe un sistema de circuitos de control de calentador mejorado para proporcionar mediciones de seguridad agregadas o redundantes o para reducir la fuga de corriente de un elemento de calentador durante el control de modulación de ancho de pulso del calentador; también se describen mejoras en la aplicación de presión negativa durante una fase de drenado en terapia de diálisis peritoneal y para controlar la cantidad de acumulación de fluido intraperitoneal durante una terapia; también se describen mejoras en eficiencia en el movimiento de fluido hacia adentro y hacia afuera de un casete de dos bombas y bolsa del calentador de un ciclador de diálisis peritoneal y en la sincronización de la operación de dos o más bombas en un ciclador de diálisis peritoneal u otros dispositivos de manejo de fluido que utilizan una disposición de múltiples bombas.

    Abstract: A system for electronic patient care includes a hub. The hub is configured to 5 monitor a patient-care device. The sandbox may be configured to control access to at least one of a hardware resource and a software resource. The hub is further configured to identify the patient-care device and execute an application to monitor the patient-care device. The hub executes the application within the sandbox component such that the application accesses the at least one of the hardware 10 resource and the software resource through the sandbox component. The hub may be further configured to control the patient-care device. The hub may be further configured to receive an identification from the patient-care device and download the application from a server associated with the identification. The hub may be further configured to receive an identification from the patient-care device and 15 update the application from a server associated with the identification. 16777902_1 (GHMatters) P97425.AU.3 23/11/2020

    Abstract: A peristaltic pump, and related system method are provided. The peristaltic pump includes a cam shaft, first and second pinch-valve cams, first and second pinch-valve cam followers, a plunger cam, a plunger-cam follower, a tube receiver, and a spring-biased plunger. The first and second pinch-valve cams are coupled to the cam shaft. The first and second pinch-valve cam followers each engage the first and second pinch-valve cams, respectively. The plunger cam is coupled to the cam shaft. The plunger-cam follower engages the plunger cam. The tube receiver is configured to receive a tube. The spring biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thereby disengages the spring-biased plunger from the tube. A spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube.

    Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include a control system that can adjust the volume of fluid infused into the peritoneal cavity to prevent the intraperitoneal fluid volume from exceeding a predetermined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting the next therapy cycle. The control system may also adjust the dwell time of fluid within the peritoneal cavity during therapy cycles in order to complete a therapy within a scheduled time period. The cycler may also be configured to have a heater control system that monitors both the temperature of a heating tray and the temperature of a bag of dialysis fluid in order to bring the temperature of the dialysis fluid rapidly to a specified temperature, with minimal temperature overshoot.

    Abstract: A wearable infusion pump assembly. The wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system also includes at least one optical sensor assembly, a first valve assembly configured to selectively isolate the pump assembly from the reservoir. The fluid delivery system further includes a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set. The at least one optical sensor assembly is configured to sense the movement of the pump assembly.
