A system for controlled delivery of medical fluids to a patient includes an inlet conduit attached to a source of a medical fluid and an outlet conduit connected to the patient. The inlet and outlet conduits are interconnected by a multiple stage control valve assembly and a pair of syringes. The control valve assembly is alternated between a first state wherein the inlet conduit communicates with a first syringe for transmitting fluid from the source to the first syringe, a second state wherein the first syringe communicates with a second syringe and is isolated from the inlet conduit and the outlet for transmitting fluid from the first syringe to the second syringe, and a third state wherein the second syringe communicates with the outlet and is isolated from the inlet and the first syringe for transmitting fluid from the second syringe to the patient through the outlet.

A Luer-like non-standard quick disconnect medical fluid connector that cannot be engaged with a standard Luer fitting.

An access port for providing subcutaneous access to a patient is disclosed. In one embodiment, the port includes an internal body defining a fluid cavity that is accessible via a septum. A compliant outer cover including silicone is disposed about at least a portion of the body. A flange is included with the port body and is covered by the outer cover. The flange radially extends about a perimeter of the port body proximate the septum so as to impede penetration of a needle substantially into the outer cover in instances where the needle misses the septum. The flange can further include both an anchoring feature for securing the outer cover to the port body and an identification feature observable via x-ray imaging technology for conveying information indicative of at least one attribute of the access port. The outer cover provides a suitable surface for application of an antimicrobial/antithrombotic coating.

An apparatus 100 for use in tube feeding comprises a cylindrical body 110 provided with a first opening 120 and a second opening 130 connected by a flow channel 140. The body 110 comprises reagent 111, for determining a characteristic of fluid disposed in the body and a transparent window 112 through which the reagent 111 is visible. In use, a first end of an enternal feeding tube releasably engages with the first opening 120. The second, distal end of said feeding tube is disposed inside a patient to be fed. A second feeding tube engages with the second opening 130. The second feeding tube connects the apparatus 100 to a bi-directional pump operable: to pump enternal fluid from a reservoir, through the apparatus and into the enternal feeding tube; and to pump fluid from the patient into the body 110 of the apparatus 100. This allows a user to pump fluid from the patient into the body 110 of the apparatus 100 to react with the reagent 111. This thereby provides an indication of the acidity of the fluid and hence whether the second end of the feeding tube is disposed in the patent's stomach before commencing feeding.

A fluid path set and method of use thereof is disclosed. The fluid path set includes a multi-patient fluid path section adapted for fluid connection to at least one pressurizing device, a per-patient fluid path section adapted for fluid connection with a patient, and a connector for removably and fluidly connecting the multi-patient fluid path section with the per-patient fluid path section. The connector includes a first connector member having an outer housing member and a first luer member recessed within the outer housing member, and a second connector member having a second threaded member and a second luer member recessed within the second threaded member. The first luer member and the second threaded member cooperate to securely and releasably connect the first connector member with the second connector member to establish removable fluid connection between the multi-patient fluid path section and the per-patient fluid path section.

A catheter system may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending through the distal end of the catheter adapter and the proximal end of the catheter adapter. The catheter system may include a catheter extending distally from the distal end of the catheter adapter. The catheter system may include a connector coupled to the catheter adapter and comprising a septum. The catheter system may include a blood collection adapter coupled to the connector. The blood collection adapter may be configured to create a fluid path through the connector. The catheter system may include a blood collection set coupled to the blood collection adapter. The blood collection set may include a needle assembly configured to receive a blood collection container.

Aspects of the present disclosure describe a vacuum luer lock connector comprising a male luer configured to couple to a female luer defining a fluid passageway, a vacuum chamber between the male luer and female luer that entraps air when the male luer is pushed into the female luer, a solid cylinder that surrounds the male luer and acts as a piston, a cylindrical member that surrounds the female luer and acts as the walls of the vacuum chamber and a vent passage in the female luer that allows air to escape when the male luer is pushed into the female luer. The male and female luers are held connected by a force created in the vacuum chamber that surrounds the luers.

Bubble traps for use in medical fluid lines and medical fluid bubble trap systems are disclosed herein. In some embodiments, the bubble trap is configured to trap gas (e.g., air) that flows into the bubble trap from a fluid line. In some embodiments, the bubble trap includes an inlet and an outlet and a chamber between the inlet and the outlet. For example, in some embodiments, the bubble trap is configured to inhibit gas from flowing into the outlet once gas flows into the chamber from the inlet. In some embodiments, the bubble trap is in fluid communication with a source container, a destination container, and/or a patient.

A flush syringe with a syringe coupler facilitates twice dispensing of intravenous flushing solution to a patient's vascular access device (VAD), with reduced risk of VAD infection. The syringe coupler incorporates a female, first Luer connector on its proximal end that is removably coupled to the male, barrel Luer connector of the syringe, isolating the latter connector from external contamination. The syringe coupler also has a single-use, male, second Luer connector on its distal end of the housing that is adapted for coupled insertion into the patient's VAD, for delivery of at least a portion of the flushing solution retained within the syringe. After the first delivery, the syringe coupler is de-coupled from both the VAD and the syringe. Thereafter, the syringe's unused, sterile, male, barrel Luer connector is directly coupled to the VAD for dispensing the second portion of the flushing solution.

The present application includes a sheath that is suitable for use in a variety of medical procedures. In one or more implementations, the sheath includes a shunt member, and a curvable portion. The curvable portion may be configured in various orientations to facilitate an intervention, such as a hemodialysis intervention, or the like, by an operator. The curvable portion may be configured to bend between a substantially straight configuration and a curved configuration. In implementations, the sheath may be configured to have detachable and/or interchangeable components (e.g., shunt member, curvable portion, etc.).
