  • Patent number: 8182452
    Abstract: A medical connector is described which is formed by a body having an inlet port, an outlet port through a male luer portion of the body, and a fluid path between the inlet port and the at least one outlet ports. A retractable post extends through the fluid path in the male luer sealing a tip of the male luer thereby closing the fluid path when the connector in not activated. Barbs extending along the exterior of the male luer and connected to the retractable post, wherein when the connector is activated, the barbs force the retractable post away from the tip of the male luer thereby opening the fluid path through the medical connector. A retention member applies force to the post to force the post to seal the tip of the male luer with the medical connector is not activated.

  • Patent number: 8167866
    Abstract: A method for accelerating subcutaneous absorption of a fluid or drug into the systemic circulation of a specific targeted tissue. A first drug operative to produce local capillary vasodilatation and/or increase the rate of bulk flow of solution through the interstitial space is mixed with a fluid. The fluid may contain a crystalloid solution or a dilute solution of a pharmacologic drug required for a routine or emergency therapeutic treatment for a patient. The first drug is substantially non-toxic to the patient. The fluid mixed with the first drug is then delivered subcutaneously or into deeper tissues of the patient, by use of a hyperdermic needle or infiltration cannula. As the capillaries are dilated, the fluid is efficiently absorbed and circulated systemically.

  • Patent number: 8162919
    Abstract: An ophthalmic surgical system utilizes a needle through which fluid is aspirated from a surgical site, and a sleeve coaxially received over the needle to define a flow passage between the sleeve and needle through which fluid is communicated to the surgical site. The system further includes a container that provides an adjustable infusion pressure for urging the flow of irrigation fluid to the surgical site. An aspiration pump urges aspiration of fluid from the surgical site, and a sensor detects the rate of aspiration flow. A controller is configured to calculate an intraocular eye pressure based on the infusion pressure and a pressure drop due to a resistance to the flow rate, which flow includes the sensed flow rate and a predicted leakage selected from a look-up table based on a size of the needle, a size of a sleeve, and a size of an incision through which the needle and the sleeve are placed.
