    摘要: An enhanced catheter introducer and method for making the same are disclosed. The catheter introducer may have a splittable sleeve assembly configured to be inserted into a blood vessel with a cannula. The cannula may then be removed, and a catheter may be inserted into the sleeve assembly. The sleeve assembly may be removed from the catheter by pulling handles of the sleeve assembly in different directions to split the sleeve assembly into two pieces. The sleeve assembly may have failure zones that enable the sleeve assembly to be easily split; the failure zones may take the form of thinned regions running along the length of the sleeve assembly. The sleeve assembly may be injection molded with a single step by injecting flows of molten plastic into a cavity of a mold such that the flows converge into an even distribution about the circumference of the sleeve. The mold may have a core pin designed to fit into the cavity. Through the use of the even distribution of flows, the core pin may seat within the cavity in an untensioned manner.

    摘要: Infusion sets for insertion into an insertion site for preventing misalignment of the base and cap or fluid connector by providing one or more alignment features between each, and in alternative embodiments, provide one or more features to secure the cap or fluid connector to the base in anyone of a number of rotational positions and having release features to allow the cap or fluid connector to be rotatable with respect to the base portion of the infusion set, and yet easily removed and inserted. Further embodiments provide infusion sets wherein the user can easily see the insertion site of the catheter and the skin, to determine if infections have occurred at an earlier stage than was possible using prior art infusion sets and with substantially less difficulty.

    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.
