    Abstract: A system and method to automatically initiate an injection procedure of a medicament into a patient. In the system, a delivery assembly includes an injector for infusing the medicament into the patient. Further, the system includes a monitor for detecting a parameter characteristic of the procedure, for instance, a pressure indicative of a partial vacuum between the injector and the injection site, a pressure exerted by the patient against the delivery assembly, a conductance, a capacitance, or an optical blood reading. Also, the system includes a timer for determining compliance of the parameter within a predetermined range during a first time interval. In response to the timer, an actuator initiates the injection procedure at the expiration of the first time interval. Further, the actuator may stop the injection procedure if the parameter is outside the predetermined range during a second time interval.

  • Patent number: 9144645
    Abstract: A novel one-piece fluid reservoir assembly for use in conjunction with an insulin infusion pump. The single piece fluid reservoir assembly includes a barrel body, a male luer fitting integral with the barrel body, a sealing surface integral with the barrel body, the sealing surface for sealing against the pump housing when the fluid reservoir assembly is inserted into the pump housing. Further, the barrel includes, as part of the one-piece fluid reservoir assembly, threads for engagement with threads on an opening in the fluid pump so that the fluid assembly can be inserted into the fluid pump, engage the threads and rotation therewith will locate the fluid reservoir assembly within the pump. Thereafter, a piston in the pump may be incrementally advanced to act upon a plunger in the barrel assembly to force a fluid within the barrel assembly through the male luer fitting and through a conduit engaged therewith to a remote infusion set.

  • Patent number: 9084529
    Abstract: In a special mode, a first frame image including a blue signal B1, a green signal G1, and a red signal R1 is captured in a first frame period. In a second frame period, a second frame image including a blue signal B2, a green signal G2, and a red signal R2 is captured. An oxygen saturation level calculator calculates an oxygen saturation level of each pixel based on signal ratios B1/G2 and R2/G2, and sequentially outputs obtained special images on a monitor. Whenever the special image is produced, a signal ratio R2/R1 is calculated. When the signal ratio R2/R1 exceeds a threshold value, a warning sign “!!” is displayed. When the signal ratio R2/R1 is larger than a predetermined range S, a warning sign “HIGH StO2” is displayed. When the signal ratio R2/R1 is smaller than the range S, a warning sign “LOW StO2” is displayed.

  • Publication number: 20150073274
    Abstract: A medical fluid injection system may include a powered injector and a fluid reservoir that contains a simulated contrast medium. The simulated contrast medium may exhibit a fluid flow property substantially equal to that of an active contrast medium but be devoid of any active contrast agent that provides contrast during diagnostic imaging. During operation, a syringe in the powered injector may be filled with the simulated contrast medium and then evacuated to discharge the simulated contrast medium from the syringe. The simulated contrast medium may be used to test and evaluate the performance of the powered injector prior to use in a medical procedure without exposing personnel to an active contrast agent or creating medical waste that contains the active contrast agent.

  • Publication number: 20150065872
    Abstract: A catheter has a shaft that defines a delivery lumen, for example, to deliver an elongate medical device therethrough; a proximal section of the catheter includes a seal zone portion, a handle portion and a proximal port portion. A relatively thin wall section of the proximal port portion extends between the seal zone portion and a proximal edge that defines part of a perimeter of a proximal opening of the delivery lumen. The handle portion projects laterally from the seal zone portion, generally opposite the relatively thin wall section. An inflation subassembly of the catheter includes a compliant sleeve member and an inflation lumen extending from the sleeve member, proximally along the shaft, and into a connector port formed in the handle portion. The inflation lumen may be formed by fusing a section of a tube to the shaft and molding the handle portion around another section of the tube.
