  • Patent number: 9017295
    Abstract: A syringe adapter with a ball-typed valve has a base, a dosing tube mounted around the base and a resilient valve mounted in the base and the dosing tube. The base has a guiding groove and an inner liquid channel communicating with each other, as well as an exhaust channel. Liquid medicine injected into the syringe adapter flows through the guiding groove and causes the inner liquid channel to be injected into a patient's body. The liquid medicine remaining in the split is cleaned when cleaning fluid is injected to clean the syringe adapter. Air in the syringe adapter flows out through the exhaust channel and is not injected into the patient's body, so the patient is free from pain. Furthermore, elements and assembling processes of the syringe adapter are simplified and manufacturing cost of the syringe adapter is lowered.

  • Patent number: 8973622
    Abstract: Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container.

    Abstract: Method and apparatus are disclosed for forming a sealed communication between conduits or conduit subassemblies, each of which has a wall with an exterior surface, and at least one of the walls includes an electrically conductive portion. The exterior surfaces may be brought into a facing relationship, and each conductive portion is heated sufficiently to sterilize the exterior surfaces of the walls by generating electrical current in the conductive portion, such as by application of a voltage or by induction. An aperture is then provided, as by an aperture-forming member, through the facing walls to provide communication between the conduits or conduit subassemblies.

  • Patent number: 8444628
    Abstract: A valve for selectively permitting a fluid flow between first and second medical implements is disclosed. The valve has a housing with an interface suitable for receiving a connector portion of a first medical device such as a catheter, and a seal made of a flexible material. The seal has a first end in fluid communication with the interface, a second end suitable for receiving the second medical device, and at least one slit in fluid communication with the first end and the second end. The slit defines a restricted fluid flow path and a relatively small interior volume when in an undisturbed state, defines an expanded fluid flow path and a larger interior volume upon the introduction of the second medical instrument into the slit, and retracts to define a restricted flow path and a small interior volume upon the withdrawal of the second medical device from the seal.

  • Patent number: 8419075
    Abstract: An end fitting (31) is formed at the patient end of an inner cannula (3) for a tracheostomy tube (1) by punching small holes (33) close to one end (34) of an ePTFE shaft (30). The end is then swaged to form an expanded region (30?) and a preformed tubular insert (40) of a thermoplastic material is inserted to cover the holes (33) on the inside. An outer part (46) of the same thermoplastic material is then overmolded on the outside of the shaft 30 so that its material (47) flows through the holes (33) and bonds with the inner insert (40), thereby securing the inner and outer parts together around the end of the shaft.

  • Patent number: 8388894
    Abstract: An apparatus for sterilizing a tubular medical line port, having a cap with an open distal end and a cavity therein which is dimensioned to receive an outer scrubbing member and the medical line port. Outer disinfected-impregnated scrubbing member is coaxially received in the cavity and has a socket therein dimensioned for engaging exterior side surfaces of the tubular medical line port when inserted into the socket for thereby scrubbing exterior surfaces of the port with the scrubbing member by rotating the cap. The outer scrubbing member is axially displacable downwardly in the cavity by insertion of the medical line port therein from an upper position prior to use to a lower position where it is retained to thereby indicate that the apparatus has been used and should not therefore be reused. A reuse prevention insert is also provided in the cavity of the cap and is displacable with the outer scrubbing member from the upper position prior to use to the lower position during and after use.
