    Abstract: PROBLEM TO BE SOLVED: To effectively prevent the careless infection of a particulate bacterium or virus in air or an accident which occurs when blood is collected. SOLUTION: A cannula consists of a housing provided with an inlet and an outlet to form a fluid passage between them, a means for forming an access hole which communicates with the fluid passage, and a flexible means which is supported by the housing to seal the access hole, and which is provided with an opening to be re-sealed and a curved outer peripheral front surface inside, with which the blunt cannula is sealed and inserted through the opening to be re-sealed, arranged by communication with the passage concerning the fluid and is removed from the arrangement, and which flexible means mutually works with the housing to re-seal the opening to be re-sealed in the case of removal.

    Abstract: An infusion pump (110) includes a housing (112); a rotor (230) inserted into the housing, the rotor including a first ring (38a) of surfaces (236a) that form channels with the housing, and a second ring (38b) of surfaces (236b) that form channels with the housing, the second channel forming surfaces radially offset from the first channel forming surfaces; and a motor (40) operably engaged to rotate the rotor to cause the first and second channel forming surfaces to pump a flow of fluid, the radial offsetting of the second channel forming surfaces from the first channel forming surfaces dampening a pulsatility of the flow of fluid.

    Abstract: A needleless connector (450) is provided which utilizes a resealable preslit septum valve (402). The valve (402) is resiliently restrained relative to a housing (418) with the valve and housing configured to accept a standard male luer lock having a luer tip (18) which penetrates the valve through the opening to extend within the housing and a luer locking flange of the luer lock extending about the housing. The valve (402) includes a disk shaped upper portion (404) covering the opening, a lower portion (406) spaced from the housing (418) and extending downward from the disk shaped portion into a passageway defined by the housing (418), and an annular skirt (408) to attach the septum to the housing. The connector (450) exhibits satisfactory leak pressure after multiple connections and disconnects to the luer lock fitting and long periods of indwell of the luer tip (18).
