A system and method that includes inserting a needle of a phacoemulsification handpiece into an eye of a patient and vibrating the needle in a first trajectory. Matter from the eye is aspirated via an aspiration line while the needle is vibrated in the first trajectory. An indication is received, of a vacuum level in the aspiration line. Determined is, that the vacuum level has changed by at least a preset vacuum level change, and in response vibrating the needle is switched to a second trajectory, different from the first trajectory.

A gravity fed peritoneal dialysis (“PD”) machine includes: a frame configured to be set on a supporting surface; at least one load cell; a scale platform supported by the frame via the at least one load cell positioned between the frame and the scale platform; a drain container support in mechanical communication with and extending downwardly from the scale platform, the machine configured such that when the frame is set on the supporting surface, at least one fresh PD fluid supply container is supportable by the scale platform above the at least one load cell and at least one used PD fluid drain container is supportable by the drain container support below the at least one load cell, so that a combined weight of fresh PD fluid and used PD fluid may be sensed by the at least one load cell.

An appliance is provided for negative-pressure therapy of wounds on the human or animal body in which, on the one hand, a substance is delivered to a wound bed (W) and, on the other hand, fluids, in particular an exudate and the delivered substance, are aspirated from the wound bed by negative pressure. The appliance has a suction pump housing, with a suction pump arranged therein for aspirating the fluids from the wound bed (W), and a fluid collection container for collecting the aspirated fluids. Moreover, the appliance has a first measuring device and a second measuring device. The first measuring device serves to determine the quantity of the aspirated fluids, and the second measuring device serves to determine the quantity of the substance delivered to the body.

A system for compounding medications. The system includes one or more compounding devices, and a central computer system. The central computer system receives requests, at least some of which require the compounding of one or more medications, and pushes assignments of respective compounding tasks to the one or more compounding devices. The assignments are made in accordance with a set of rules designed to promote efficient use of compounding resources.

A fluid management system including a pass-through fluid volume measurement system to provide continuous measurement of fluid returned from a surgical site during transit to a waste collection system. The pass-through fluid volume measurement system eliminates the need to physically replace full fluid collection containers during the medical procedure with new, empty fluid collection containers.

A processor of a medical device configured to communicate with a remote server can be programmed to protect the medical device from exposure to unauthorized or malicious software. A system or method to implement this form of protection can include, for example, at least one processor on the medical device, a control software module that controls the operation of the medical device and is executable on the processor, a data management module that manages data flow to and from the control software module from sources external to the medical device, and an agent module that has access to a limited number of designated memory locations in the medical device. In addition, a hemodialysis apparatus can be configured to operate in conjunction with an apparatus for providing purified water from a source such as a municipal water supply or a well. A system for controlling delivery of purified water to the hemodialysis apparatus can comprise a therapy controller of the hemodialysis apparatus configured to communicate with a controller of a water purification device, and a user interface controller of the hemodialysis apparatus configured to communicate with the therapy controller, and to send data to and receive data from a user interface.

A fill adapter system for an infusion pump assembly. The system includes a reusable fill adapter base, the base including a volume control mechanism to adjust an available fill volume of a reservoir of the infusion pump assembly and a pump mechanism configured to pump air into a fluid vial. The system also includes a vial adapter assembly including a first needle configured to penetrate a septum of the fluid vial for fluidly coupling the pump mechanism to the fluid vial and a second needle having a first end configured to penetrate the septum of the fluid vial and a second end configured to penetrate a septum of the reservoir of the infusion pump assembly to allow transfer of fluid from the fluid vial to the reservoir of the infusion pump assembly in response to air being pumped into the fluid vial and a needle carriage adapted to carry the first needle and the second needle, wherein the needle carriage slidably attached to the interior of the vial adapter assembly, wherein the needle carriage adapted to slide from a vial end of the vial adapter to a receptacle end of the vial adapter.

Methods, systems, and kits are provided for performing hemodialysis, hemodiafiltration, and peritoneal dialysis on a portable machine suitable for both clinical and home use. Peritoneal dialysate can be flowed into and out of the peritoneal cavity, and can also be regenerated within the system, without the need for introducing fresh dialysate. Common hardware and software can be utilized for both peritoneal dialysis and other forms of dialysis such as hemodialysis, hemofiltration, and hemodiafiltration, allowing for facile transition between different dialysis modes using the same dialysis machine.

A CRRT apparatus comprising a filtration unit (2), a blood circuit (17), a blood pump (21), a dialysate line (13) and one or more lines (8; 51; 57; 58; 63; 69; 67; 74) to transfer a respective solution into blood; a fluid source for each of said one or more lines, wherein said solution comprises at least one buffer agent in the form of bicarbonate or bicarbonate precursor. A control unit (12) is configured to receive a patient prescription and to determine a parameter (J.sub.buffer_load/BW) indicative of a steady state acid-base balance in the blood of the patient who has to undergo a CRRT blood treatment, wherein said parameter is determined as a function of the concentration of said buffer agent in said fluid source and as a function of the estimated or calculated patient systemic steady state concentration of bicarbonate and/or bicarbonate precursors.
