  • Patent number: 10502350
    Abstract: A quick water intake device comprises a tubular main body. The main body has a channel, and a first seal core, and an elastic piece. Under the action of the elastic piece, the first seal core can block the channel. A second seal core is also slidably arranged inside the main body. The second seal core is located between the first seal core and an outlet end of the main body, and when subjected to forces, the second seal core can move toward the first seal core and drives the first seal core to compress the elastic piece. A sealing structure arranged between an outer wall of the second seal core and an inner wall of the main body can form a seal between an outer wall of the second seal core and the main body to block the channel when the second seal core moves toward the outlet end.

  • Patent number: 9528649
    Abstract: A female coupling member includes a coupling member body having a fluid passage and being configured to receive a male coupling member from a front end thereof, and a valve member disposed in the coupling member body to traverse the fluid passage. The valve member has an opening and is displaceable between an open position and a closed position. In the open position, the valve member communicates between a front end side and a rear end side of the fluid passage through the opening. In the closed position, the opening is located outside the fluid passage to close communication between the front end side and the rear end side of the fluid passage. The valve member has a purge passage configured to communicate with both the front end side of the fluid passage and the atmosphere outside the female coupling member when the valve member is in the closed position.

  • Patent number: 9415200
    Abstract: A soft grip medical connector comprises a housing with an upstream end, a downstream end and a lumen extending through a central portion thereof. A flexible member comprises a valve portion integrally formed with a sleeve portion. The valve portion is positioned within a section of the housing and is configured to control a flow of fluid through the housing lumen. The sleeve is inverted to envelope at least a portion of the outer surface of the housing. In some embodiments the gripping portion is integrally formed with the valve portion. In some embodiments, the connector is also generally configured to create a positive pressure in a catheter lumen upon removal of a syringe or other medical device from the upstream end of the connector.

  • Patent number: 9308362
    Abstract: A male needleless connector includes a body having a male fitting with a distal port, a valve disposed within the body and having a first position wherein the valve seals the port and a second position wherein the valve does not seal the port, and a sliding seal disposed over a portion of the male fitting and having a first configuration wherein a first portion of the sliding seal is in sealing contact with the male fitting and a second configuration wherein the first portion is not in sealing contact with the male fitting. Moving the sliding seal to the second configuration opens the seal between the sliding seal and the male fitting and displaces the valve to the second position, thereby opening the seal between the valve and the port.

  • Patent number: 9283318
    Abstract: A sealing assembly for a fluid infusion device includes a base plate, a reservoir port receptacle, a flow base component, and a needle sealing element. The receptacle receives the reservoir port, and has proximal and distal ends, and a needle entry in the distal end to receive a hollow needle of a fluid reservoir. The flow base component has an inlet structure defining a fluid chamber, and a needle guide pin protruding therefrom. The end of the guide pin fits within the hollow needle. The needle sealing element has a proximal flange adjacent to the inlet structure, a distal flange opposite the proximal flange, a neck section between the flanges, and a needle opening extending through the neck section. The needle sealing element is positioned within the port receptacle such that the neck section surrounds the end section of the needle guide pin.

  • Patent number: 9238128
    Abstract: A bottomed, tubular hollow elastic body that opens toward an outlet side of a drug solution flow path is accommodated and arranged in an accommodation part formed in a housing, and a middle protrusion is provided protruding toward an inlet side of the drug solution flow path from a center part of a bottom wall of the hollow elastic body. Insertion of a male luer causes the bottom wall of the hollow elastic body to be elastically deformed so as to enter inside a peripheral wall, increasing the volume of the drug solution flow path, which is formed between an outer surface of the hollow elastic body and an inner surface of the accommodation part. Removing the male luer and canceling the elastic deformation of the hollow elastic body causes the volume of the drug solution flow path to be reduced.

  • Patent number: 9238129
    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: 9109721
    Abstract: An apparatus for filtering water has an interface and a filtration/purification canister removably mountable onto the interface. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. The interface provides for water boiler expansion pressure relief, while guarding against any water contaminated downstream of the apparatus from backflowing into the filtration/purification canister and contaminating the portion of the filtration/purification canister downstream of the filter/conditioning/purifying medium held within the filtration/purification canister and thereby causing water exiting the outlet port of the filtration/purification canister to be contaminated.
