  • Patent number: 9078965
    Abstract: Embodiments disclosed herein include systems and methods for administering a drug over a time period. One embodiment of a system includes an administration unit, a housing that houses the administration unit, and a controller unit adapted to receive an alarm triggering signal. Also included in some embodiments is an alarming unit that is adapted to generate an alarm signal on reception of the alarm triggering signal. Some embodiments include a patient state monitor that includes a motion-sensitive sensor unit that is reactive on patient motion. The patient state monitor may be adapted to process a sensor signal generated by the motion-sensitive sensor unit. The patient state monitor may also be adapted to transmit the alarm triggering signal to the controller unit if a patient motion level is below a predefined motion level, as determined by a length of time without patient motion.

  • Patent number: 9044538
    Abstract: A power injector (40) includes a movable ram (74) operable to interface with and move a plunger (90a/b) of a syringe (86a/b). The power injector (40) may be operable to automatically determine a proper home position for a particular type of the syringe (86a/b) to be used in a fluid injection sequence. The power injector (40) may also include a ram homing logic (182) operable to automatically move the ram (74) to the home position after the injection sequence. Such automatic homing of the ram (74) may, for example, be initiated by an end of the injection sequence in preparation for another injection sequence, by opening of a faceplate (102a/b), by a user input, or by any combination thereof.

  • Patent number: 9022969
    Abstract: A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

  • Patent number: 8961471
    Abstract: In accordance with at least one exemplary embodiment, a syringe device, a method and a system for delivering a therapeutic amount of ozone are disclosed. A sterility case can enclose a syringe portion and can maintain sterility while the syringe device is interfaced to an ozone generator. A valvably-controlled fluid channel can extend from a barrel of the syringe portion through the case. Conducting elements can be attached to the case and can breach the case. The conductive elements can be connected to electrodes. The electrodes can be attached to the syringe portion. The syringe portion can be filled with oxygen gas via the valvably-controlled fluid channel. An electric current can be provided to the conductive elements from the ozone generator resulting in a corona discharge from at least one of the electrodes. The therapeutic amount of ozone can be produced from the oxygen gas and the syringe portion delivered into a sterile field without compromise.

  • Patent number: 8951229
    Abstract: A catheter includes a pressure actuated seal within a manifold. A catheter body is coupled with the manifold, and a manifold lumen and a catheter lumen are configured to receive pressurized fluids. The pressure actuated seal includes a pressure actuated seal element having a seal element lumen. The seal element lumen is in communication with the manifold and catheter lumens. The pressure actuated seal element is deformable between an open configuration and a sealed configuration. In the sealed configuration, the pressurized fluids in the manifold press on the pressure actuated seal element along a first seal face. The pressure actuated seal element compresses inwardly around the seal element lumen according to a pressure of the pressurized fluids. In the open configuration, the pressure actuated seal element relaxes in an absence of the pressurized fluids, and the seal element lumen is open and configured to allow passage of an instrument.

  • Patent number: 8945041
    Abstract: Fluid removal systems and methods for removing a fluid from a tissue site are presented. The systems includes a semi-permeable inbound conduit, which is fluidly coupled to a treatment-fluid delivery unit, for placement proximate to the tissue site, and a semi-permeable outbound conduit, which is fluidly coupled to the inbound conduit and to a treatment-fluid collector, for placement proximate to the tissue site of a patient. The treatment-fluid collector receives a treatment fluid and the fluid, which is recruited, from the tissue site. A recruited-fluid determination unit may be coupled to the treatment-fluid collector to determine a volume of the recruited fluid recruited from the patient. The treatment fluid is any fluid (including a gas) that pulls the recruited fluid from an interstitial and intracellular space. A reduced-pressure treatment subsystem may also be included, among other things, for removing ascites and other fluids from a body cavity.

  • Patent number: 8939959
    Abstract: A simple method and device enabling a unit dose from a reservoir is provided. The dose is drawn into the reservoir and is then expelled from the device by depressing a plunger. The plunger has features which divide the dose into discrete intervals. As the plunger is moved during delivery, the features on the plunger and features connected to a barrel interact to provide for intermittent stops to the delivery. Other aspects of the device provide for reduced dead space, safety and selective interconnection with other devices. Thus, the device divides the dose.

  • Patent number: 8932275
    Abstract: A surgical seal assembly, includes a seal housing defining a longitudinal housing axis and having a longitudinal opening therethrough, a seal having an inner seal portion defining a passage and being adapted to form a substantial seal about a surgical instrument disposed within the passage and a guide mounted to the seal housing. The guide has an inner guide portion proximal of the inner seal portion of the seal and spaced therefrom. The inner guide portion defines a channel adapted to generally direct the surgical instrument toward the inner seal portion of the seal upon entry of the surgical instrument within the longitudinal opening of the seal housing. The inner guide portion is relatively compliant to accommodate initial offset or angled entry of the surgical instrument.

  • Patent number: 8926549
    Abstract: A handle for a medical instrument having a handle housing that can be closed by a cover and having at least one drainage or irrigation hose in the handle housing that can be connected to a hose connection support. To create a handle that is of a simple construction and ensures a reliable fluid-proof insulated connection of the at least one hose and the hose connection support while protecting a material of the at least one hose, it is proposed that each drainage or irrigation hose should be connectable by an adaptor to the hose connection support and that the adaptor upon closing the handle housing can be pressed against the hose connection support by a stop positioned on the cover or on a base portion of the handle housing.
