    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.

    摘要： A medical device includes a vascular access device with an access port having a septum and a slit. The slit is formed on the inner surface of the body of the septum where the access port receives an access device that is separate from the vascular access device through the slit of the septum. A pivoting member in communication with the access port pivots when the port is accessed by an access device. The medical device may be used to control the volume displacement of a chamber within the medical device by decreasing the volume of the chamber by inserting a substance having a mass into the chamber, pivoting a structure associated with the chamber, and increasing the volume of the chamber simultaneously and commensurately with the mass of the substance inserted into the chamber.

    摘要： A vascular access device within an external environment may include a body and a septum at least partially housed within the body, a gas chamber housed within the body and the septum, and a vent adjacent the body capable of facilitating gas transfer between the gas chamber and the external environment. A method of venting a gas chamber within a medical device includes transferring gas between the gas chamber and an external environment of the device through a vent that is adjacent the body of the device.

    摘要： A peripheral catheter having a catheter tip diffuser for reducing an exit velocity of an infusant within the catheter. Pluralities of diffusion side holes are provided on the tip portion of the catheter. Some examples further include pluralities of annularly arranged, staggered diffusion holes provided on the tip portion of an intravenous catheter to streamline infusant issued from the diffusion holes. An inner surface of each diffusion hole is further angled relative to the inner surface of the catheter lumen such that an infusant within the lumen exits the catheter though the diffusion holes at an angle less than 90°.
