The present technology relates to a headgear for a patient interface, comprising one or more straps each having a first end for connecting to a mask. The first end of each strap comprises a connection portion which is grippable by a user to pull the strap to increase a tension in the strap, a first rigid member and a second rigid member that extends from a resilient carrier that is connected to the connection portion. The second rigid member is movable relative to the first rigid member when the connection portion is pulled. At least part of the second rigid member is arranged to strike the first rigid member to cause at least an audible alert when the second rigid member travels further than a threshold distance. The resilient carrier is constructed and arranged such that the threshold distance corresponds to a desired tension limit for the strap.

A universal respiratory detector for detecting a respiratory gas. The universal respiratory detector may include a plurality of layers with a visual indicator to quickly and reversibly change color to detect a respiratory gas parameter such as carbon dioxide. The color change may be visible from both sides of the detector. In some examples, the respiratory detector may be a biocompatible and conformable sticker for mounting on a person’s face or an oxygen delivery device.

This invention relates to a breath indicator that is receivable by a part of a breathing assistance apparatus that supplies gas to a patient. The indicator comprises an elongate body having a gas sampling end and an attachment end. The attachment end is adapted to attach to a part of a breathing assistance apparatus and for locating the gas sampling end. The gas sampling end is to be located in a region where gas from the patient is to be exhaled. The gas sampling end being in communication with a sensor comprising a detector material changeable between a first visual indicator state relating to an inhalation phase of the patient, and a second visual indicator state relating to an exhalation phase of the patient. The detector material is capable of changing between the visual indicator states at a sufficient rate to substantially correspond with the inhalation and exhalation phases of the patient.

An IV set includes an IV component and a duration monitor device coupled to the IV component. The duration monitor device may include an indicator portion configured to change color after a determined amount of time upon activation of the indicator portion, or an RFID tag configured to be detected by an RFID reader. The duration monitor is configured to provide an indication of passage of a useful-life time period for the IV set or the IV component. Methods of operating a duration monitor device are also provided.

A method for analysing a device for spraying a pharmaceutical fluid product including the following steps: providing a spray head of a device for spraying a pharmaceutical fluid product, the spray head having a spray orifice; providing a receiving surface having a plurality of discrete contact zones separated by voids, the contact zones capable of being coated with a heat sensitive material, bringing the receiving surface to a temperature T2, passing a flow of compressed gas through the spray orifice, the flow of compressed gas at a temperature T1 which differs from T2, sending the flow of compressed gas at temperature T1 onto the receiving surface at temperature T2, visualising the impact zone for the flow of compressed gas on the receiving surface, and analysing the visualisation of the impact zone in order to determine whether the spray head complies with predetermined specifications.

Drainage catheters configured to be visible by echogenicity and/or echopacity are provided. Drainage catheters including layers or marker bands configured to be visible by echogenicity and/or echopacity are further provided.

A patient interface includes a sealing arrangement adapted to provide an effective seal with the patient's nose, an inlet conduit arrangement adapted to deliver breathable gas to the sealing arrangement, and a cover that substantially encloses the sealing arrangement and/or the inlet conduit arrangement.

An apparatus including a tubular channel having a pathway extending between a proximal end and a distal end of the tubular channel. The proximal end is configured to connect directly or indirectly to an end tidal CO.sub.2 monitor. The distal end has an opening. The apparatus further includes a detection member including a chamber disposed in fluid communication with the pathway of the tubular channel such that gas entering the tubular channel via the opening on the distal end passes into the chamber. A detection element is disposed within the chamber and includes a component that is sensitive to one or more systemic biomarkers such that, upon exposure to a predetermined concentration level of the one or more systemic biomarkers contained in the gas, a state of the detection element experiences a permanent alteration and the detection member indicates that the predetermined concentration level of the one or more systemic biomarkers is present in the gas.

A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

The present invention relates to a kit comprising: a) an ampoule; b) a material comprising a hemp plant or parts thereof; and c) a color indicator capable of reacting by contacting the hemp plant and/or at least a part thereof to change the color of the color indicator, wherein the material and the color indicator are disposed in the ampoule; and a method for qualitatively and/or quantitatively detecting one or more substance(s) contained in the hemp plant using the kit.
