Devices for transferring fluid to or from a subject include an extension tube assembly with an axially extending inner tube configured to couple to an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen and an axially extending inner tube. The inner tube extending through the tubular cannula defines an exposed needle tip and is in fluid communication with the inner tube of the extension tube assembly. The needle tip extends out of a distal end of the tubular cannula a suitable distance.

A housing includes a cavity portion and a cover portion configured for rotary motion. The cover portion can include a receiver port configured to engage with a fitting configured for coupling to an end of a first tube. At a first alignment position of the cavity portion relative to tire cover portion, the receiver port is aligned with a first retention cleat. At a second alignment position of the cavity portion relative to the cover portion, the receiver port is aligned with a fluid coupler. At a third alignment position of the cavity portion relative to the cover portion, the fitting is aligned with a second cap.

The invention relates to a PEG probe having a PEG tube, an outer holding plate, through which the PEG tube is fed and in which the PEG tube is fastened, and a funnel adapter, which is associated with an outer end region of the PEG tube. A tightly closing valve is arranged either in the PEG tube between the outer holding plate and the outer end region or on the outer end region of the PEG tube. The valve blocks the flow through the PEG tube in a closed position and allows said flow at least in the full cross-section of the PEG tube in an open position. The valve has a valve body and a valve housing. The valve body is connected to and movable by means of a handle accessible from outside. The valve body is supported in the valve housing.

Systems, methods and devices are described including a medical device subassembly including a magnetic feature. Systems include such a catheter adapter subassembly or needle subassembly or guidewire introducer subassembly and a wire including a magnetic feature, and relative movement of the catheter adapter subassembly or needle subassembly or guidewire introducer subassembly and the wire can be determined using an magnetometer.

Disclosed is a disposable needle filter apparatus with a universal truncated syringe-receiving neck to enable the filtration of fluids/solutions aspirated into a needle-bearing syringe. The apparatus includes a needle seal stopper and needle stop to create a substantially airtight chamber to facilitate fluid aspiration through an enclosed filter and into the syringe. In an alternative embodiment, the filter apparatus includes an extended syringe-receiving neck configured to receive a specifically sized syringe/needle combination. In a further embodiment, the receiving neck is constructed as a modular unit to allow for interchangeable necks to accommodate different needle and syringe sizes with different cross-sectional diameters. In a yet further embodiment, the neck is constructed with stepped tapered segments of serially larger cross-sectional diameters to accommodate differently sized syringes. In a still further embodiment, the apparatus includes an accessory needle secured to the apparatus inlet.

An adapter constructed to have a proximal portion that interfaces with the internal lumen of a medical device and a distal portion that modifies, augments or extends the configuration or intended use of the medical device. The proximal portion of the adapter interfaces with the internal lumen of the medical device in a manner to secure the adapter to the medical device during use. The distal portion of the adapter is generally outside the lumen of the catheter or device.

A delivery adapter which may be used as an interface between a syringe and a catheter hub is described.

A method for administering chemotherapy medicament, which comprises providing a closed-system drug administration kit, performing sterile catheterization on a patient by placing at least the distal tip of the catheter into the patient's bladder to drain the bladder, inserting a syringe containing the medicament into a safety adapter at a proximal end of the catheter to prevent leakage during attachment, injecting the medicament into the bladder with the injector through the adapter and the drain lumen without leakage of the medicament from the patient into an environment while assessing a pain level of the patient, removing the syringe and closing the catheter to hold the medicament in the bladder for a given treatment time, and, after the given treatment time, draining the medicament out of the bladder with a medicament pressure reservoir through the catheter and into the medicament pressure reservoir for disposal of the kit.

An enema adapter attaches to a plurality of bottles, shower hoses, or water hoses as the fluid storage vessel or fluid source for body cavity flushing applications, such as enema, douching, or similar applications. The enema adapter directs the flow of water from the into the body cavity for medical or hygienic needs. The enema adapter includes discharge nozzle, a first mounting adapter, at least one discharge opening, and a nozzle cap. The discharge nozzle focuses and directs fluid flow from a fluid reservoir out through the at least one discharge opening into the user's body cavity. The discharge nozzle attaches to the first mounting adapter. The first mounting adapter secures the enema adapter to the fluid reservoir.

A delivery adapter which may be used as an interface between a syringe and a catheter hub is described.
