Patent number: 6019748Abstract: A medical valve has a body which includes a wall structure defining an internal cavity having an inside and an outside. The body also has a proximal end and a distal end. The proximal end has an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through the delivery end. The body has a fluid escape space in its wall structure. The valve also has a spike with a tip and at least one hole located at or near the tip. The spike has a passageway in communication with the hole that allows fluid to flow through the spike. A resilient seal in the cavity surrounds the spike. This seal is adapted to be moved into a compressed state upon insertion of the tip of the medical implement into the opening. The seal is sufficiently resilient to return to a decompressed state upon removal of the tip of the medical implement from the opening. The fluid escape space is in fluid communication with the outside of the cavity when the seal is in its compressed state.Type: GrantFiled: April 6, 1998Date of Patent: February 1, 2000Assignee: ICU Medical, Inc.Inventor: George A. Lopez

Patent number: 5971950Abstract: Disclosed is a connector for introducing medication into a patient in a safe, convenient way. It comprises a pair of plastic tubular members adapted to be manually pushed together to engage in a male-female relationship, and a locking mechanism that detachably secures the members together. The male member has a sealed entry port at its end, and the female member safely houses within it a needle which centrally pierces the seal of the port upon engagement of the members. Preferably, the locking mechanism provides a "click" sound when it locks the members together.Type: GrantFiled: October 6, 1997Date of Patent: October 26, 1999Assignee: ICU Medical, Inc.Inventors: George A. Lopez, Virgil R. Laul

Patent number: 5928204Abstract: A closed system, needleless valve device includes a generally tubular body defining an internal cavity. On the proximal end of the body there is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The distal end of the body has a generally tubular skirt. The valve also includes a hollow spike having a closed tip. The spike includes at least one longitudinal 18-gauge hole located distal the tip, and is seated inside the cavity such that the tip is below the proximal end of the body. An annular support cuff is connected to the spike which seals off a portion of the cavity of the body such that an upper cavity containing the tip is defined. The valve also includes a plastic, resilient silicone seal which fills the upper cavity and opening and covers the tip of the spike so as to present a flush surface. An adaptor enables the valve to be attached to a resealable container.Type: GrantFiled: June 7, 1995Date of Patent: July 27, 1999Assignee: ICU Medical, Inc.Inventor: George A. Lopez

Patent number: 5810768Abstract: A medical connector is for use in transferring fluids to and from a patient. The connector has a primary conduit, which has an upstream branch in fluid communication with a primary source of fluid and a downstream branch in fluid communication with a patient. The connector also has a secondary conduit in fluid communication with said primary conduit. Additionally, the connector has a hollow, resilient valve positioned such that the primary fluid can flow through the valve when the valve is in a decompressed state. The valve has a tab extending into the secondary conduit such that a luer inserted in the secondary conduit compresses the tab, thereby preventing flow of the primary fluid through the connector while permitting both flow of fluid to the patient from the luer and flow of fluid from the patient to the luer.Type: GrantFiled: June 7, 1995Date of Patent: September 22, 1998Assignee: ICU Medical, Inc.Inventor: George A.

Patent number: 5330450Abstract: A safety connector is provided for connection to the branch port on a fluid flow line. The connector comprises a tubular body having an opening at its distal end to receive a branch port and a channel in the wall of the tubular body adjacent to the distal end. The channel is adapted to receive the fluid flow line when the branch port is engaged within the tubular body. The connector also comprises a locking rotatable collar located on the distal end of the tubular body. The collar is rotatable from a first position wherein the channel is adapted to receive the fluid flow line when the branch port is engaged within the tubular body, and a second position wherein the collar prevents the removal of the branch port from the tubular body.Type: GrantFiled: August 17, 1993Date of Patent: July 19, 1994Assignee: ICU Medical, Inc.Inventor: George A.
