摘要： A method of preventing blood leakage through a septum of a catheter assembly when a needle is disposed within a slit of the septum may include providing a lubricant within multiple gaps disposed between an outer surface of the needle and the slit. The lubricant may include a viscosity greater than 1,000 centipoise. Providing the lubricant within the multiple gaps may include applying the lubricant to the outer surface of the needle, and inserting the lubricated needle distally through the slit of the septum. Providing the lubricant within the multiple gaps may include applying the lubricant to a tip of a septum actuator of the catheter assembly, and penetrating the septum with the lubricated septum actuator. Providing the lubricant within the plurality of gaps may include dispensing the lubricant within the slit of the septum prior to insertion of the septum into the lumen of the catheter adapter.

摘要： A system for confirmation of fluid delivery to a patient at the clinical point of use is provided. The system includes a wearable electronic device. The wearable electronic device has a housing; at least one imaging sensor associated with the housing; a data transmission interface; a data reporting accessory for providing data to the user; a microprocessor for managing the at least one imaging sensor, the data transmission interface, and the data reporting accessory; and a program for acquiring and processing images from the at least one imaging sensor. The system further includes a fluid delivery apparatus; and one or more identification tags attached to or integrally formed with the fluid delivery apparatus. The program processes an image captured by the at least one imaging sensor to identify the one or more identification tags and acquires fluid delivery apparatus information from the one or more identification tags.

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°.

摘要： An obturator assembly includes an obturator positionable within a lumen of a device and movable within the lumen between a first position and a second position. The obturator includes a distal tip portion, wherein, with the obturator in the first position, the distal tip portion limits fluid communication through the lumen and, with the obturator in the second position, the distal tip portion provides fluid communication through the lumen.
