The present invention relates to a valve system for an inflatable portion of an indwelling medical device and more particularly to a valve system for fluid regulation of a catheter comprising a fluid inflatable portion that undergoes pressure changes within the body during use.

An aseptic connector assembly includes a body portion having a receptacle configured to receive a corresponding fill connector. A pivot portion is movably coupled to the body portion, the pivot portion having a channel formed therein. A conduit portion is slidably disposed within the channel formed in the pivot portion. The pivot portion has a ready position and an operative position, the pivot portion being adjustable from the ready position to the operative position via relative movement with respect to the body portion.

A medical instrument for diagnostic, therapeutic, or surgical measures in a cavity in the body of a patient may include a proximal region, which is provided and designed for arrangement outside the body, a distal region, which is provided and designed for arrangement inside a cavity in the body, a supply structure for delivering a fluid to the cavity, wherein the supply structure reaches from a first coupling in the proximal region of the medical instrument to an outlet in the distal region, and a discharge structure for discharging a fluid from the cavity, wherein the discharge structure reaches from an inlet in the distal region of the medical instrument to a second coupling in the proximal region of the medical instrument. The flow resistance of the supply structure is greater than the flow resistance of the discharge structure.

In one aspect, a valve includes an interior channel for permitting a fluid to flow through the valve and an opening to the interior channel, the opening including a circular portion and a tapered portion adjacent the circular portion, the tapered portion having a maximum width that is less than a diameter of the circular portion, wherein the valve is rotatable about a central axis of the valve to adjust a position of a cross-sectional area of the opening with respect to a cross-sectional area of an inlet fluid line positioned to deliver the fluid to the rotary valve.

A check valve includes a housing that includes an inlet port, an outlet port, and a valve chamber. The inlet port extends from a ceiling of the valve chamber to an outer surface of the housing. The outlet port extends from a floor of the valve chamber to the outer surface of the housing. The check valve further includes a valve member supported within the chamber. The valve includes a valve head. When an upstream pressure is applied to the valve, the valve head is configured to deflect away from the ceiling of the valve chamber and unseal the inlet port. When a downstream pressure is applied to the valve, the valve head is configured to deflect away from the floor of the valve chamber and seal the inlet port such that the valve head conforms to a shape of the ceiling of the valve chamber.

A suction/irrigation medical device valve system comprises a first valve plunger configured for insertion into a first valve plunger channel. The first valve plunger has a first latch member disposed at a distal end with a first sealing member and a first valve opening disposed proximally from the first latch member. The system also comprises a second valve plunger configured for insertion into a second valve plunger channel. The second valve plunger includes a second valve opening that is longer than the first valve opening. The system also comprises a valve body having the first and second valve plunger channels. The first and second valve plunger channels are configured to receive the first and second valve plungers, respectively.

A waste management appliance includes a tubular body having a proximal end and a distal end, a cowl fastened to the tubular body at a first circumferential location in a vicinity of the proximal end, a balloon provided within the cowl, and an inflation lumen opening to an interior of the balloon and extending toward the distal end of the tubular body. The cowl extends outside of the tubular body to a second circumferential location spaced from the first circumferential location and is fastened to the tubular body at the second circumferential location. The balloon is inflatable to a desired extent within the cowl by injecting a predetermined amount of fluid into the balloon via the inflation lumen; the cowl restrains inflation of the balloon beyond the desired extent in the event of an injection of more than the predetermined amount of fluid into the balloon.

A fluid transfer connector comprises a medical standard connector part comprising a fluid transfer port, a connector part for flexible tubing, the connector part arranged to form a fluid connection with the fluid transfer port such that, in use, a fluid flow can pass between flexible tubing connected to the connector part and the fluid transfer port. The connector further comprises a moveable member arranged to interrupt the fluid flow in the flexible tubing when moved from a first position to a second position. The moveable member is further arranged to release a connection, in use, between the medical standard connector part and a corresponding adaptor part such as a female hub).

A flow control device includes a housing having a primary valve body defining a primary inlet and an outlet, a secondary valve body defining a secondary inlet, and a chamber defined by an inner circumferential surface of the housing and fluidly connecting the primary and secondary inlets with the outlet. The primary and secondary inlets share a common central axis perpendicularly disposed to a central axis of the outlet. A valve member is reciprocally mounted in the chamber to block fluid communication between the secondary inlet and the outlet when fluid pressure into the primary inlet is higher than fluid pressure into the secondary inlet, and) block fluid communication between the primary inlet and the outlet when fluid pressure into the secondary inlet is higher than fluid pressure into the primary inlet.

A compact and smart wearable device is configured to automatically inject medicines into the wearer. Because hypodermic needles are only deployed when triggered, infection risks are eliminated. Necessary medicines are automatically deployed based on physiological or other data without human intervention to save lives.
