A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to air and water channels of an endoscope. One or more embodiments described herein may include cleaning valves with features and/or components that facilitate differentiating them from procedural valves. In some embodiments, valves may be made from a limited number of parts and materials, to limit their cost. For example, multiple seals may be formed as a single component, such as via overmolding. In another example, wiper seals may be used to accommodate greater manufacturing tolerances. In yet another example, the valve may have a single elastomeric component, or spring cap, which may combine the functionality of a number of components (e.g., a boot, spring, spring housing, and stem cap).

A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to fluid (e.g., air and water) channels of an endoscope. Many embodiments described herein may include a cleaning valve (or valve) that is appropriate for single-use and therefore may be disposable. Accordingly, the valve may be made from a limited number of parts and materials, e.g., to limit its cost and/or manufacturing complexity. For example, multiple seals may be integrally formed with a valve stem. In another example, the valve may have an interface member, which may combine and simplify the functionality of a number of components, such as by connecting the valve stem to a valve well, sealing an opening to a lumen in the valve stem, and/or biasing the valve stem into a position relative to the valve well.

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.

The invention relates to an insertion device comprisinga penetrating member (50) connected to transformation means (52), a moving part (38) comprising guiding means (39) which guiding means (39) restrict the movement of the transformation means (52) and guide the penetrating member (50) from a first to a second position in a first direction, i.e. the direction of insertion, towards the injection site, anda stationary housing (30) comprising guiding means (32) which guiding means (32) restrict the movement of the moving part (38). The guiding means (32) guide the moving part (38) in a second direction which is linear and different from the first direction i.e. the direction of insertion.

A needle-free connection device include a casing, a connection base, a slide element and a resilient valve. The casing includes a first hollow tube having a first liquid transmission channel. The connection base is connected to the casing. The resilient valve includes a second hollow tube and a plug connected thereto, wherein the second hollow tube has a second liquid transmission channel, a third liquid transmission channel is formed between the second hollow tube and the plug, and a fourth liquid transmission channel is formed between the connection base and the plug. The first to the fourth liquid transmission channel are intercommunicated with each other. The connection base includes a third hollow tube, and a fourth liquid transmission channel is formed between the plug and the third hollow tube. The needle-free connection device provides a liquid transmission path sequentially passing through the first to the fourth liquid transmission channel.

Some embodiments disclosed herein relate to a medical connector with an internal cavity with an internal closure system having a dome valve configured to resist retrograde fluid flow caused by various sources, including patient activity and fluid administration activity. A proximal closure system with a seal member and a moveable plug are also located within the internal cavity.

A medical fluid connector, having a first body with a tube section with an inlet and a first thread, a second body with an outlet and a second thread that engages the first thread to move the first and second bodies between closed and opened positions. The second body has a third thread that is configured to rotate in the opposite direction in relation to said first and second threads. The connector has a closure cap with a fourth thread that, in a delivery state of the fluid connector, is detachably screwed to the third thread of the second body, wherein the fluid connector assumes the open position, and wherein the outlet is closed off in an air-permeable and liquid-tight manner by means of the closure cap.

An injection port assembly including a body having first and second mating structures configured to mate with a first connector for a first fluid pathway and a second connector on a device, respectively. A resilient barrier substantially contained within the body and compressible from a first position in which fluid flow between the first and second connectors is blocked to a more compressed second position in which fluid flow between the first and second connectors is permitted. A hollow cannula can be coupled with the first mating structure and disposed within the resilient barrier, the hollow cannula having a distal end configured to extend through the resilient barrier when the resilient barrier is in the second position, the distal end having lateral slots. The resilient barrier can have first and second annular sealing rings positioned above and below the lateral slots respectively.

Disclosed is a first medical connector configured to be removably attachable with a second medical connector to permit fluid flow between the first and second medical connectors. The first medical connector can include a first region with a luer-compatible connection portion being configured to engage luer-compatible medical devices, and a second region comprising a resilient seal and a first luer-incompatible connection portion. The first luer-incompatible connection portion can inhibit engagement with luer-compatible medical devices and permit engagement with a second luer-incompatible connection portion of the second medical connector. In some embodiments, the first region of the first medical connector does not rotate with respect to the second region of the first medical connector in an initial stage of use, but the first medical connector is configured to transition from the initial stage of use to a subsequent stage of use in which the first region of the first medical connector and the second region of the first medical connector can be rotated with respect to each other.

A connector system for medical fluid includes a male connector and a female connector that have a closed configuration when detached from one another. The first end of the male connector is configured to mate with a first end of the female connector. When the male connector is coupled with the female connector, complementary structures engage to move seals away from ports in the male connector and the female connector, opening a fluid pathway through the connectors. The mating ends of the connectors are not exposed to the medical fluid when the connectors are coupled so that when the connectors are disconnected, the mating ends are substantially free of residual medical fluid.
