A method for assembling a drug delivery device that includes mounting a cartridge with a bung, the mechanism, the plunger and the spring within a housing such that a spring biases a plunger in a dispensing direction and that a drum and/or the release member is attached to the plunger attaching a tool with torque measurement capability to the drum or a release member of a dose mechanism in a state where at least one housing part is detached from further housing part; setting a dose by rotating the dose setting member in a first direction, activating a trigger and monitoring the torque applied to the drum or the release member; releasing the trigger upon detection of a predetermined change in the torque measured by the tool; and releasing the tool and closing the housing.

A medical connector of the present invention is characterized in that: when a male connector portion is inserted into a female connector portion, a first locking portion is engaged with the female connector portion to achieve a first locked state as well as a second locked state; when the second locked state is released by operation of a second unlock operating portion and the female connector portion is moved in a disengagement direction with respect to the male connector portion, the locking member is moved in the disengagement direction together with the female connector portion while keeping the first locked state; and when the female connector portion is rotated with respect to the male connector portion, the first locked state is released.

Tubing retention systems are described herein. A tubing retention system includes a spigot, a tubing, and a collar. The spigot includes a spigot body and a spigot extension extending from the spigot body, wherein the spigot extension comprises a flared portion opposite to the spigot body and the spigot body and the spigot extension cooperatively define a spigot lumen. The tubing includes an outer surface and a tubing lumen, wherein a coupling portion of the tubing is disposed around the spigot extension, permitting fluid communication between the tubing lumen and the spigot lumen. The collar is disposed radially around the outer surface of the tubing and axially between the flared portion and the spigot body, wherein the collar radially engages the coupling portion of the tubing disposed around the spigot extension to axially and radially retain the tubing with the spigot.

A surgical port includes a first end, a second end opposite the first end, and a longitudinal axis extending through the first end and the second end. An outer sidewall extends between the first end and the second end. First and second channels extend through the port from the first end to the second end. A first electrically conductive portion extends from the first channel to the outer sidewall, and a second electrically conductive portion extends from the second channel to the outer sidewall. The first electrically conductive portion provides a first electrically conductive path between the first channel and the outer sidewall and the second electrically conductive portion provides a second electrically conductive path the second channel and the outer sidewall. The second electrically conductive path is separate from the first electrically conductive path. Devices and methods relate to surgical ports.

A cushion assembly for a patient interface includes an elastomeric seal-forming portion with a dome-shaped superior region that is intersected by the sagittal plane in the vicinity of a superior tangent point. The seal-forming portion further including a saddle-shaped inferior region that is intersected by the sagittal plane and includes an inferior tangent point. A first support region is located on one side of the sagittal plane between the inferior region and the superior region, the exterior surface of the elastomeric seal forming portion at the first support region being cylinder-shaped and/or saddle-shaped. In addition, a blowout prevention system is configured to counter a force acting on the unsupported edge of the elastomeric seal-forming portion due to a pressure within the chamber, the blowout prevention system being attached to the elastomeric seal-forming portion at the first support region of the elastomeric seal-forming portion.

A patient interface may include a plenum chamber and a positioning and stabilising structure. The plenum chamber may include a seal-forming structure and a fascia portion. At least a medial portion of the fascia portion is flexible. In embodiments, the patient interface may include a rigidiser to control flexing of the fascia portion.

An infusion tube system and a method for manufacture are provided. An infusion tube system including an infusion tube and a connector attached to the infusion tube at an end of the infusion tube is disclosed. The connector has a proximal end and includes a connector body extending from a distal end to a proximal end along a center axis and defining a cavity. The connector body includes an end wall with an inner surface, and at least one vent opening, and a sidewall extending from the end wall along the center axis with an inner and outer surface. The connector includes a membrane covering the at least one vent opening, the membrane being welded to the inner surface of the end wall along at least one welding seam including a first welding seam such that the membrane covers and seals the at least one vent opening.

A patient interface comprises a seal-forming structure including a textile membrane and a support structure to support the textile membrane. The seal-forming structure may have a varying construction in order to accommodate different regions and the varying contours of the patient's face to ensure a robust and comfortable seal. An air impermeable layer of the textile membrane may have a thickness that varies in different portions of the textile membrane and/or different regions of the cushion assembly. Further, the seal-forming structure may include an underlying cushion, and an arrangement of the textile membrane and the underlying cushion and/or the configuration of the underlying cushion may vary in different regions of the cushion assembly to optimize patient comfort and the effectiveness of the seal in different regions of the patient's face.

Apparatus and methods are described for manufacturing a housing for an impeller of a blood pump. A frame is treated in order to enhance bonding between an inner surface of the frame and an inner lining. Subsequently, the inner lining is coupled to the inner surface of the frame along at least a portion of a central cylindrical portion of the frame. Subsequent to coupling the inner lining to the inner surface of the frame along at least a portion of the central cylindrical portion of the frame, a portion of an elongate tube is placed around at least a portion of the frame. While heating the inner lining, the frame, and the portion of the elongate tube, pressure is applied such as to cause the portion of the elongate tube to become coupled to the frame. Other applications are also described.

A respiratory pressure therapy system for providing continuous positive air pressure to a patient via a patient interface configured to engage with at least one airway of the patient. The system includes: a flow generator configured to generate supply of breathable gas for delivery to the patient via the patient interface; at least one sensor; a display; and a computing device. The computing device is configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control, based on the received sensor data, the flow generator to adjust a property of the supply of breathable gas; receive, an input indicating assistance is needed with using the patient interface; receive one or more images of the patient with the patient interface; analyse the received one or more images; and based on the analysis, display instructions for positioning the patient interface.
