    Abstract: A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

  • Publication number: 20140180258
    Abstract: A needle-free connector includes a hollow connector, an elastic block, and a switch assembly. The inner perimeter of the hollow connector forms a first annular wall and a second annular wall. The elastic block is disposed in the hollow connector. The switch assembly has a stop member and a guide tube connected to the stop member, the stop member being pressed between the annular block and the elastic block, the guide tube being disposed in the hollow connector, the external perimeter of the stop member forming a first annular portion against the first annular wall and a second annular portion against the second annular wall, a groove being disposed between the first annular portion and the second annular portion of the stop member, the groove being connected to the guide tube. Thus, the structure stability and closing performance are achieved such that the outside air cannot leak into the connector.

    Abstract: A neonatal feeding tube (10) includes electronics and instrumentation for monitoring a neonate and for provides nourishment to the neonate. The tube (10) includes electrodes (20) for sensing ECG signals of the neonate. Thermistors (22, 24, 28, 30) are placed at various points along the tube (10) to measure the neonate's temperature at those points. Breathing effort is measured by calculating a pressure differential at two pressure ports (32, 34). Pulse and SpO2 are measured at a fiber optic window (35). The electrodes (20), a distal electrode (64) and a light source (66) aid in helping a caregiver position the tip (12) of the tube (10) correctly in the stomach of the neonate.

  • Patent number: 8603072
    Abstract: The male connector of the present disclosure allows for the flow of fluids therethrough and includes a movable blunt needle having a shoulder projecting radially outwards from the movable blunt needle. The male connector also includes an outer cylinder body formed around the movable blunt needle and disposed in coaxial alignment to the movable blunt needle, a blunt needle retainer which retains the movable blunt needle so that the movable blunt needle can move in an axial direction, and a valve which opens as a result of the movable blunt needle moving in the axial direction when the posterior end presses against the valve. This occurs when the movable blunt needle is inserted into a corresponding connection site, such as a female connector, and the shoulder presses against the connection site to force the movable blunt needle in the axial direction.

  • Patent number: 8535293
    Abstract: Ureteral access sheaths can have a nonuniform axial-stiffness. A nonuniform axial-stiffness ureteral access sheath can have an inner liner defining a longitudinally extending and generally uniform bore. A non-uniform axial-stiffness outer jacket can define a longitudinally tapered outer surface, and a reinforcement layer can be encapsulated between the inner liner and the non-uniform axial-stiffness outer jacket. The reinforcement layer can have a non-uniform axial-stiffness. For example, a proximal portion of the reinforcement layer can be thicker than a distal portion of the reinforcement layer. A coil of wire can be included in the reinforcement layer, and a diameter of the wire in a proximal portion of the reinforcement layer can be larger than a diameter of the wire in a distal portion of the reinforcement layer. In some instances, the diameter of the wire tapers from the proximal portion to the distal portion.

    Abstract: The present invention relates to a connection piece for an enteral transfer system and to an enteral transfer system with such a connection piece, and also to an arrangement composed of such a transfer system and of an enteral feed probe. The connection piece according to the present invention comprises a distal attachment piece for attachment of a connection piece of a probe tube of an enteral feed probe, and a proximal attachment piece for attachment of the connection tube of a transfer system. The distal attachment piece of the connection piece is conical or is designed in stepped fashion with several portions of different diameter. The distal attachment piece can therefore be releasably connected to the funnel-shaped connection pieces of different diameter of the probe tubes of the known feed probes. The connection piece according to the present invention can be used universally in this respect.

    Abstract: Drainage catheters for use in a variety of medical procedures are presented herein. The drainage catheter features an improved tension member locking mechanism. In use, once the drainage catheter is placed as desired, a second connector piece is rotated relative to a first connector piece to wind the tension member around a spooling region and pull the distal end of the catheter tube into a locked configuration. Once the tension member is tensioned, the first and second connector pieces are pulled into a locking engagement thereby securing the catheter tube in the locked configuration.
