摘要： The present invention is directed to the parenteral procurement of bodily-fluid samples. The present invention is also directed to systems and methods for parenterally procuring bodily-fluid samples with reduced contamination from dermally-residing microbes. In some embodiments, a bodily-fluid withdrawing system is used to withdraw bodily fluid from a patient for incubation in culture media in one or more sample vessels. Prior to withdrawing bodily fluid into the one or more sample vessels for incubation, an initial volume of withdrawn bodily fluid is placed in one or more pre-sample reservoirs and is not used for the incubation in culture media.

摘要： A biological liquid collection device designed to draw blood using an “atmospheric-balanced vacuum” to ensure the blood is exposed to the sample atmospheric partial pressure oxygen and partial pressure carbon dioxide levels as found in standard arterial blood gas syringes, resulting in blood gas sample stabilization during collection and a superior vacuum shelf-life by reducing the gas permeation rate through the plastic tube. The biological liquid collection device comprises a collection module for receiving a biological liquid sample, an evacuated container having an open end and a closed end wherein the evacuated container contains the collection module therein, and a closure for closing the open end of the evacuated container. The evacuated container comprises a gas composition that is substantially equal to the gas composition of the atmosphere outside of the evacuated container. A method for forming the atmospherically balanced vacuum collection device is also provided.

摘要： Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber.

摘要： A container assembly is disclosed including an outer container, a hollow inner member, and a closure. The outer container has a closed bottom, an open top, and a sidewall extending therebetween. The hollow inner member is disposed within the outer container and has an inner surface defining at least one capillary channel. The inner member includes a first end adjacent to the open top of the outer container and has an outer periphery seated against the sidewall of the outer container. The closure has a proximal end and a distal end. The closure proximal end is seated at least partially within the first end of the inner member to seal the outer container and inner member and define a fluid collection chamber. The closure distal end defines a recessed area shaped to direct fluid under capillary action to the at least one capillary channel in the inner member.

摘要： A blood sequestration device configured to isolate an initial, potentially contaminated portion of blood from the flow of blood of a patient, prior to directing the flow of blood to an outlet port where the blood can be accessed. The blood sequestration device including a body member having an interior wall defining a fluid conduit having a distal portion, a first proximal portion, and a second proximal portion, wherein the first proximal portion defines a sequestration chamber configured to isolate an initial portion of blood of a flow of blood, a vent path configured to enable the escape of gas initially trapped within the sequestration chamber.

摘要： A blood draw system may include a catheter adapter connector in fluid communication with a catheter adapter, and a blood draw device in selective fluid communication with the catheter adapter connector. A first valve may be utilized to selectively permit fluid communication between the blood draw device and the catheter adapter connector. A flush device may also be in selective fluid communication with the catheter adapter connector to flush the catheter adapter after a blood draw procedure. A second valve may be utilized to selectively permit fluid communication between the flush device and the catheter adapter connector.

摘要： An independent blood filter device depends on flow geometry to deliver blood serum or plasma free of detrimental levels of hemoglobin. It depends critically on an upstream flow rate or pressure differential limiting control element or device that limits the rate of change of pressure differential across the filter element. Pre-evacuated versions can be used to simultaneously draw blood from a living being and provide pressure differential across the filter element between an evacuated collector and a supply end open to atmosphere. A unit pressurized by hand motion employs the external shape of a partially filled blood collection tube as a piston to produce pressure in advance of the control element or device to create the pressure differential across the filter element to a collector vented to atmosphere. The control element or device is disclosed in numerous forms, including specially sized flow constrictions and compliant arrangements.

摘要： A blood collection system can include a cannula for insertion into a catheter system that comprises a hub with an internal chamber, a distal port in fluid communication with the internal chamber and coupled with a catheter tube that can be preplaced in a blood vessel of a patient, and an access port in fluid communication with the internal chamber. The cannula can be inserted in the catheter tube and can include a distal opening that is positioned within the blood vessel of a patient and is in fluid communication with an interior of the blood vessel to permit blood to flow into a lumen of the cannula, and can include a proximal opening positioned within the internal chamber to permit blood to flow from the cannula into the internal chamber and through the access port of the hub.

摘要： A blood collection device for medical use having a body with longitudinal flow channel and a needle retraction chamber, a slide assembly slidably engaging the body in a plane transverse to the flow channel through the body, a forwardly projecting nose, a device stabilization member with flexible wings projecting oppositely from a cylindrical hub attached to the nose, a rearwardly biased venipuncture needle projecting forwardly from the nose, and a tubular needle cap having proximal and distal ends, wherein the proximal end of the tubular needle cap is insertable between and is releasably held by the nose and the cylindrical hub. Cooperatively configured sets of ramps and stop surfaces limit lateral sliding movement of the body relative to the slide assembly.
