  • Patent number: 12005235
    Abstract: A drug delivery system includes a drug containing device and a drug delivery device. The drug containing device includes a chamber carrying a fluid drug and an outlet in fluid communication with the chamber. A first closure initially inhibits the fluid drug from exiting the drug containing device via the outlet. The drug delivery device includes a fluid passageway and a stem having an inlet in fluid communication with the fluid passageway. The stem displaces the first closure from the outlet and enters the outlet to provide fluid communication between the chamber and the fluid passageway and thereby facilitates delivery of the fluid drug to the drug delivery device. A second closure is coupled to the stem, and the second closure engages the first body at the outlet when the stem enters the outlet to inhibit the fluid drug from exiting the drug containing device around the stem.

Moreover, the elongated body further includes a first portion, a second portion and a flexible portion between the first and the second portions. The second portion includes a passageway for the body liquid. The valve mechanism closes to the inlet of the passageway. Furthermore, the flexible portion expands when the adjusting mechanism is in a first state to prevent the catheter from being removed from the subject, and the flexible portion retracts when the adjusting mechanism alters to a second state to allow the catheter to be removed from or inserted into the subject. Hence, the body fluid is directed to enter the passageway via the inlet and exit via the outlet when the adjusting mechanism is not in the second state.

    Abstract: A body-fluid-and-medication leak-proof and closed medical connector has a first connecting assembly and a second connecting assembly. The first connecting assembly has a first sleeve and a first resilient valve. The first resilient valve tends to seal a first opening of the first sleeve. The second connecting assembly has a second sleeve and a second resilient valve. The second resilient valve tends to seal a second opening of the second sleeve. The two resilient valves can avoid leakage of the medication remaining in an injector and a vial, or remaining in a fluid infusion tube and a catheter. The two resilient valves also can seal in two directions to avoid leakage during connecting or separating the two connecting assemblies after supplying medication. Therefore, the transfer of the medication is more hygienic and safe, and the waste of medical resources is effectively reduced.

  • Patent number: 11213456
    Abstract: A sealing device for a medication vial which is highly efficient and easy to use. The sealing device comprises a valve and a compressible stopper. Fitted vertically on top the valve and stopper is a coupling portion. When a syringe is coupled to the sealing device, the syringe compresses the stopper which in turn exposes an aperture defined in a central neck portion of the valve. As medication is withdrawn from the vial, the medication enters the valve and travels through the central neck where it then exits through its open apertures and subsequently into the syringe itself. As the syringe is withdrawn, the stopper is allowed to expand or relax which again closes the apertures defined within the central neck of the valve, thereby ceasing the flow of medication through the sealing device.

  • Patent number: 10238858
    Abstract: A connector includes a housing including: an insertion section into which a male connector is insertable from an outside of the housing, and a flow path communicating with the insertion section; and an elastic valve body having a slit and configured to block the insertion section. An inner wall of the housing defining the flow path is integrally formed with a liquid barrier face. The housing is configured such that, when the male connector is inserted in the insertion section, the liquid barrier face faces a tip opening of the male connector in an insertion direction of the male connector such that liquid flowing out from the tip opening collides with the liquid barrier face.

  • Patent number: 10117977
    Abstract: The tissue therapy device includes a sealant layer and a suction apparatus. The sealant layer creates a sealed enclosure between it and the surface of a patient by forming an airtight seal around an area of tissue. The suction apparatus is in fluid communication with the sealant layer and together, create a closed, reduced pressure therapy system. The suction apparatus self-creates reduced pressure by decreasing the density of air molecules underneath the sealant layer by expanding the volume of the air molecules.

  • Patent number: 9925365
    Abstract: A needleless injection port assembly includes first and second body parts and a resilient barrier received within the body. A cannula attached to the first body part is received within an internal cavity of the resilient barrier. The resilient barrier is moveable between a less axially compressed first position in which fluid flow through the injection port assembly is prevented and a more axially compressed second position in which fluid flow through the assembly is allowed. An interference fit is provided between the resilient barrier and the cannula to seal against fluid flow through the cannula when the resilient barrier is in the first position. The cannula has an internal fluid passageway with a non-circular cross section providing increased fluid flow.
