摘要： A medical device may include a vascular access device having a body and a membrane of the body. The membrane communicates with a pathogenic environment and discourages adhesion of a pathogen to the membrane. A method of discouraging a pathogen from residing on the membrane of a vascular access device includes providing a vascular access device with a body having a membrane and discouraging a pathogen from residing on the membrane.

摘要： A medical access device provides needleless access to patient fluid lines such as intravascular catheters. A retaining ring at the top end of the housing of the medical access device is molded around a septum that provides access for a tubular portion of a medical device such as a male luer taper of a syringe. Alternatively, the retaining ring may also be molded around the body or around both the body and the base of the housing. The molded retaining ring and septum are attached by mechanical attachment and/or chemical adhesion to minimize axial and rotational movement between the septum and the housing.

摘要： A catheter and introducer needle assembly with needle shield is provided wherein the needle includes an enlarged diameter portion and a distally facing shoulder. The needle shield includes a means for engaging the distally facing shoulder to prevent unwanted distal movement of the needle once the needle has been withdrawn into the needle shield. The needle shield also includes a small diameter opening adjacent to its proximal portion to limit proximal movement of the needle out of the needle shield.

摘要： An apparatus to automatically secure an end of a needle after contact with a blood vessel. The apparatus may include a housing and a biasing member, where the housing includes a hollow interior region extending between a proximal end and a distal end thereof. A proximal opening may be integrated into the proximal end, while a distal opening may be integrated into the distal end. The proximal and distal openings may be configured to receive a needle therethrough along a longitudinal axis. The biasing member may be coupled to the housing and configured to apply a force to the needle. The force may be oriented to displace the needle relative to the longitudinal axis upon retracting an end of the needle through the distal opening into the hollow interior region. Embodiments of the present invention may thus secure the end of the needle within the hollow interior region after use to prevent accidental needle sticks and exposure to blood and blood-borne pathogens.

摘要： An apparatus to control blood flow through an intravenous catheter in accordance with the present invention may include an intravenous catheter adapter and a blood control valve. The blood control valve may be retained within a hollow interior region of the intravenous catheter adapter, and may include a resilient outer shell and an inner valve portion extending inwardly therefrom. The inner valve portion may include a slit configured to open, coin-purse style, upon radially compressing the resilient outer shell. In some embodiments, a compression feature may be integrated into the intravenous catheter adapter to radially compress the resilient outer shell. A Luer device, for example, may be inserted into the intravenous catheter adapter to translate the blood control valve to a position substantially corresponding to the compression feature, thereby actuating the compression feature to open the slit.

摘要： A catheter insertion device with an automatic safety barrier includes a housing, a barrier member, and a biasing element. The housing includes a central bore configured to receive a needle therethrough, and further includes a channel extending through the housing and intersecting the central bore. The barrier member is hingedly coupled to the housing, and includes a leg to extend through the channel. An opening in the leg substantially aligns with the central bore to accommodate the needle therethrough. The biasing element biases the barrier member relative to the housing such that withdrawing the needle through the opening causes the biasing element to misalign the opening with the central bore, thereby occluding the central bore to shield an end of the needle.
