A connection apparatus for a medical device includes a first connection member having a first end and a second end with the first connection member defining at least one channel adjacent the first end. The at least one channel having a first portion extending in an axial direction and a shoulder adjacent to the first end of the first connection member that defines a channel entry. The at least one channel having a second portion extending in a transverse direction relative to the axial direction. The connection apparatus further including a second connection member having a first end and a second end and at least one protrusion adjacent the first end. The shoulder is configured to guide the at least one protrusion of the second connection member into the channel entry regardless of the orientation of the at least one protrusion relative to the channel entry.

A bronchoscope locking mechanism includes a clamping member and a nut. The clamping member includes a threaded portion and a clamping surface that defines a compressible channel. The compressible channel is configured for communication with a tracheal tube. The nut has an inner threaded surface configured to cooperate with the threaded portion of the clamping member. The compressible channel is compressed from a first position defining a first diameter to a second position defining a second diameter when the nut is advanced over the threaded portion. The second diameter is smaller than the first diameter.

A injection site information cap includes a housing, a cover portion, an engagement portion configured to couple to and cover an injection port of an injection site, and at least one information element on the cover portion that is positioned to be automatically sensed by at least one sensor of the injection site when the engagement portion is coupled to or is being coupled to the medication injection port. Related apparatus, systems, and techniques are also described.

Connectors for medical devices include visual and tactile features as an indicator of a connection-type of the connector. This allows for differentiation by type of connection under busy and/or low light conditions.

A respiratory treatment apparatus configured to provide a flow of breathable gas to a patient, including a breathable air outlet, an outside air inlet, and an pneumatic block module, wherein the pneumatic block module includes: a volute assembly including an inlet air passage, a mount for a blower and an outlet air passage; the blower being mounted in the mount such that an impeller of the blower is in a flow passage connecting the inlet air passage and the outlet air passage; a casing enclosing the volute assembly, wherein air passages within the casing connect air ports on the volute assembly, wherein the inlet air passage of the volute assembly is in fluid communication with the outside air inlet and the outlet air passage of the volute assembly is in fluid communication with the air outlet.

A medical connector includes a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end, a helical thread extending radially outward from a surface of the sidewall and comprising a crest portion, flank portions, and a root portion with the flank portions connecting the root portion to the crest portion, and at least one micro-thread extending radially outward from the surface of the sidewall. At least a portion of the micro-thread is spaced apart from the helical thread.

A gas feeding/suction valve includes: a cylinder including a conduit opening communicable with a fluid conduit of an endoscope; two coupling members provided at different positions from the conduit opening of the cylinder and connected to respective fluid sources; and an operation member provided inside the cylinder and including a shaft slidably disposed in a space forming respective fluid paths through which openings of the two coupling members and the conduit opening communicate with each other, and the cylinder includes a sounding body provided near at least one of two ventilation ports, through which the fluid paths communicate with an outside of the cylinder, and configured to generate a warning sound when a fluid flows in a direction opposite to a direction in which a fluid generated from the fluid source is supposed to flow.

A connector interface system includes a cap to connect to a reservoir to form a reservoir/cap unit for installation into an infusion pump device. The cap has at least one receptacle for receiving one or more detectable features comprising at least one disc-shaped member, for detection by at least one sensor element on the infusion pump device when the reservoir of the reservoir/cap unit is received in a reservoir receptacle of the infusion pump device. The at least one detectable feature has at least one detectable parameter that is associated with one or more characteristics of the cap, the reservoir, the infusion pump device, a cannula associated with the cap or a tubing connected between the cap and the cannula.

A syringe comprising a syringe barrel having a distal end, a distal tip, a proximal end, a barrel sidewall extending between the distal end to the proximal end and defining a chamber, the barrel sidewall having a barrel sidewall thickness t, the distal end of the syringe barrel including a distal wall is disclosed. The syringe includes a connector extending from the syringe barrel including a collar disposed coaxially around an elongate tip in fluid communication with the barrel to form a channel between the elongate tip and the collar, including an inside surface, an outside surface and a plurality of ribs extending radially outwardly from the outside surface and separated by spaces, each of the plurality of ribs having a height H and a width W, wherein there is a ratio of the height H to the barrel sidewall thickness tin a range of 0.75 and 1.
