An intravenous therapy system may include a hollow needle comprising a distal end and a proximal end, the distal end comprising a sharp tip for insertion into a vein; an infrared (IR) camera placed within a hollow portion of the hollow needle, including: an IR detector; a first light source to emit a first wavelength of IR light; and a second light source to emit a second wavelength of IR light; a comparator to, upon execution of a processor communicatively coupled to the comparator, compare an amount of reflected light received at the IR detector during activation of the first light and second light and provide an indication of light absorption within a vein.

A plunger gasket with reduced surface contact area including a body, a first side defining a first side surface, a second side defining a second side surface, and at least one surface feature projecting outwardly from at least one of the first or second side surfaces. In example embodiments, at least one surface feature projects outwardly from both the first and second side surfaces. By reducing the surface areas of contact between gaskets during manufacture and processing, the incidence of unintentional cohesion may be reduced or eliminated.

Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. An elastomeric seal without a guide member is positioned within the internal cavity. A rigid, hollow elongated portion is located within the internal cavity such that in an open configuration, a tip of the elongated portion is more proximal than a proximal surface of the elastomeric seal. A distal portion of the elastomeric seal is seated radially within a region surrounded by a plurality of longitudinally extending protrusions.

Nonpathogenic microorganism preparations for delivery to the intranasal system, kits including nonpathogenic microorganism preparations for delivery to the intranasal system, and devices for administering nonpathogenic microorganism preparations to the intranasal system are provided. Vehicles for intranasal delivery of nonpathogenic microorganisms are provided. Ammonia oxidizing microorganism preparations for delivery to the intranasal system, kits including ammonia oxidizing preparations for delivery to the intranasal system, and devices for administering ammonia oxidizing preparations to the intranasal system are provided. Vehicles for intranasal delivery of ammonia oxidizing microorganisms are provided.

A medical female connector (10) for controlling a fluid flow is disclosed, as well as a method for its manufacturing, and medical devices including such a female connector. A tubular plunger (40) and a flexible valve member (60) are inserted into a housing (20). A distal end (42) of the plunger (40) is located at a distance proximally from the distal end (22) of the housing (20). In a flow stop configuration, the flexible valve member (60) seals a flow path (44) through the tubular plunger (40). In a flow configuration, the valve member (60) is compressed by a male connector (90) and deformed by the plunger (40) to allow a fluid flow through the plunger (40). A frusto-conical female sealing surface (24) is arranged to form a seal with the male connector (90). An entrance opening (25) of the housing (20) presents a diameter equal to or larger than the maximum diameter (d1) of the female sealing surface (24).

A medicament for inhalation is provided. The medicament comprises at least a first layer comprising a first active pharmaceutical ingredient in powder form and at least a second layer comprising at least a second active pharmaceutical ingredient in powder form. The second layer is disposed on the first layer. A container for dispensing a medicament and methods of making are also described.

A support member for use in a sealing assembly of a patient interface device for delivering a flow of a breathing gas to the airway of a patient. The support member includes: a first end structured to be coupled to a frame member of the patent interface device; a second end structured to sealingly engage the face of a patient or to underlie a sealing flap which is structured to sealingly engage the face of a patient; and a sidewall which extends between the first end and the second end. The sidewall is formed from a plurality of beads of material.

An oxygen delivery apparatus wearable by user includes a frame including nose pads connected to a bridge portion, an oxygen inlet defined by one of the nose pads, an oxygen inlet defined by the frame, and a hollow channel contained by the frame. The oxygen inlet and oxygen outlet are in fluid communication via the hollow channel. The frame can be formed as a monolithic structure using additive manufacturing. A nasal prong can be connected to the oxygen outlet such that a prong outlet of the prong is in fluid communication with the hollow channel. The prong outlet is positioned within a nostril of the user during use of the apparatus. A method of fabricating the frame includes obtaining measurement information for at least one of a head feature or facial characteristic of the user and generating a digital model of the oxygen delivery apparatus using the measurement information.

A dialyzer housing manufacturing system includes a molding device configured to mold a dialyzer housing, and a tool coupled to a robotic arm and configured to retrieve the dialyzer housing from the molding device after the dialyzer housing is molded. The tool includes a frame, a first suction cup connected to a first portion of the frame, and a second suction cup connected to a second portion of the frame, the second suction cup being oriented about 70 degrees to about 110 degrees relative to the first suction cup.

A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patient's nares and/or an entrance to the patient's mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patient's respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.
