A disposable valve assembly configured for use with an endoscope is disclosed. The disposable valve assembly may include a stem comprised of thermoplastic material, a spring stanchion configured to receive the stem and allow movement of the stem in an upward and downward position relative to the spring stanchion, a spring configured to contact that spring stanchion and the stem. In some embodiments, a lubricant is disposed on the stem, the spring stanchion and/or the spring. The disposable valve assembly may also include an antimicrobial agent disposed in the lubricant, or in the thermoplastic material and/or can be coated thereon. A method for manufacturing the disposable valve assemblies for use with an endoscope may include several steps.

A flow stopper preventing the backflow of urine comprises a urinary catheter connector, a flow stopping valve, and a urinary bag connector. The flow stopping valve is a membrane material. A flow channel runs through the front and rear ends of the flow stopping valve. The flow channel is provided with a front-end inlet and a rear-end outlet. The front-end inlet is in communication with a valve port of the urinary catheter connector. The rear-end outlet is a flat slit. A channel of the urinary bag connector is provided with a front-end port and a rear-end port connected to a tube of a urinary bag. The flow stopping valve is arranged within the channel. Moreover, the rear-end outlet of the flow channel faces the rear-end port of the channel. The flow stopper can prevent the backflow of the urine and prevent a patient from being infected.

A respiratory filter and condensate management apparatus is provided for use in a breathing circuit during patient respiration. The apparatus includes a housing having an air inlet port for receiving a flow of respiratory air, and an air outlet port for outputting the flow of respiratory air to a ventilator. A filter compartment is provided within the housing and includes a filter member located in a flow path of the respiratory air from the air inlet port to the air outlet port. A condensate collection compartment is provided within the housing and includes at least one reservoir and at least one self-sealing drainage port. The reservoir collects liquid formed by condensation of the respiratory air within the filter compartment, and the drainage port allows removal of the collected liquid from the reservoir while the housing remains connected to the breathing circuit.

Delivery devices for administering drugs are disclosed. An example apparatus, includes a body including: a handle in which a syringe assembly is to be disposed; a base having a bottom face to be disposed adjacent a user; and an absorbent material attached to the bottom face, the absorbent material structured to hold a fluid to be released onto the user prior to or during an injection procedure.

A system for use in treating a tissue site with negative pressure, which may comprise a dressing or tissue interface and a plurality of standoffs for storing and releasing a biocompatible polymer to the tissue site. The standoff may be cells or closed-end cells. In some examples, the biocompatible polymer may comprise collagen, oxidized regenerated cellulose, or a combination thereof. Method for using and manufacturing the dressing or tissue interface may also be disclosed.

A coated urinary catheter or urinary stent device includes a urinary catheter or stent which, in a deployed position, includes or defines a protective surface area and a protected surface area and a coating upon at least a portion of the protective surface area. The coating includes a lubricant and an antimicrobial and/or pH buffering material. The device is configured such that, upon application of negative pressure to the catheter or stent, tissue of a urinary tract of a patient conforms or collapses onto the protective surface area and is thereby prevented or inhibited from occluding one or more protected drainage holes, ports or perforations of the catheter or stent.

A tamper resistant catheter device preventing unauthorized access, while permitting authorized intravenous medications through an inlet port. The device comprises a catheter line retainer having a base supporting the catheter line, a lumen adaptor engaged with the catheter line, and a locking clamp for clamping the catheter line within the catheter line retainer. An installation tool is provided having a breakaway handle and a locking cap for covering the lumen adaptor. Finally, a slotted retaining sleeve is installed using the breakaway handle of the installation tool for engagement with the locking cap and around the lumen adaptor. The slotted retaining sleeve engages the locking clamp to block removal of the locking clamp from the line retainer. Once the slotted retaining sleeve and locking cap are installed, the breakaway handle is removed. A removal tool disengages the locking cap from the slotted retaining sleeve for authorized access.

A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

Flush syringe assemblies are described herein. Such flush syringe assembly may include a barrel including a side wall defining a chamber, an open proximal end, a distal end having a distal wall with an elongate tip extending distally therefrom having a passageway therethrough in fluid communication with said chamber. A collar may be mounted on the distal wall of the barrel and surrounding the elongate tip. A disinfectant-loaded swab may be disposed in the collar. The flush syringe assembly may also include a removable cap.

The present invention is directed to wall box for hemodialysis interface having two isolated zones. The first zone is a clean interface zone having sources of purified water and dialysis fluids. The second zone is a waste interface zone comprising waste connectors and a waste drain.
