A surgical fluid management system includes a console and a cassette for delivering fluids to a surgical site. The console has a pump rotor and a pressure-sensing membrane. The cassette has a cassette housing, a flexible fluid delivery tube in the housing. The flexible fluid delivery tube has a lumen configured to interface with the pump rotor and to deliver a flow of fluid from a fluid source as the rotor is rotated. A pressure-transmitting membrane is located in a wall of the cassette housing and in fluid communication with said fluid delivery lumen. The pressure-transmitting membrane flexes outwardly in response to a positive pressure in the lumen and flexes inwardly in response to a negative pressure in the lumen. The pressure-transmitting membrane detachably adheres to or presses against the pressure-sensing membrane to cause the pressure-sensing membrane to move in response to pressure changes in the flexible fluid delivery tube.

The present disclosure provides an aerosol precursor consumable, and an aerosol delivery device that comprises a control unit that defines a receiving chamber, and a removable and replaceable aerosol precursor consumable, at least a portion of the consumable configured to be received into the receiving chamber. The aerosol precursor consumable comprises a housing defining an outer wall, an aerosol precursor composition reservoir located in the housing and configured to contain an aerosol precursor composition, an atomizer located in the housing, and at least one aroma diffuser. The atomizer is configured to vaporize the aerosol precursor composition to generate an aerosol for oral delivery to a user, and the at least one aroma diffuser is configured to diffuse an aroma composition for olfactory delivery to the user.

Disclosed are apparatus and methods of detecting user interaction with a respiratory therapy device and effecting an action in response to the detection. The apparatus comprises a sensor which is positioned so as to detect the presence of a user's hand or fingers near to the apparatus, such as a surface or handle. In embodiments the apparatus may be configured to detect gestures or movement of the user. On detection of a user, the apparatus may be configured to effect one or more actions, such as disabling a feature of an input or output device or alerting a user.

A low-cost medical pump for ambulatory use provides an improved IV line cartridge attachment allowing for single handed, low force release while preventing inadvertent IV line cartridge release. A rotatable side lever minimizes the force required to move the locking elements against a spring biased force urging the locking elements to a locking position.

A security tag can prohibit unauthorized usage of a device or product. The device may include an electronic nicotine delivery systems (“ENDS”) device, which may include aerosol delivery devices such as smoking articles that produce aerosol. The security tag can prevent usage until authorized. Attempts at usage without authorization can result in the device being unusable. The authorization may include identity confirmation or age verification.

A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.

An infusion apparatus includes a housing and a chamber configured to be connected to the housing. The apparatus further includes a weight sensor coupled to a load connector connected to the housing and an optical sensor disposed in the housing. The weight sensor is configured to generate a first signal based on a measured weight of the fluid container attached to the housing in a weight-bearing configuration. The optical sensor is configured to generate a second signal based on detecting drops of the fluid traversing the chamber. The apparatus also includes a flow control mechanism to control a flow rate of the fluid into an outlet channel. The apparatus includes one or more processing devices configured to perform operations including transmitting a control signal to the flow control mechanism to adjust the flow rate.

Vaporizer cartridges and vaporizer apparatuses, and methods for making, using and delivering vapor to a user, that are leak-resistant for use with cannabinoids. In particular, described herein are leak-resistant vaporizer cartridges and apparatuses adapted for use with oil-based vaporizable materials including cannabis oils.

This disclosure relates to a medical device including a hard part and a converter. The hard part has fluid paths for conducting a medical fluid through the hard part. The converter is arranged to measure a characteristic of the medical fluid while the medical fluid is present in one of the fluid paths. At least a section of the converter is applied or superimposed to the hard part by at least one additive application method.

A docking station for removable connection to an enteral feeding pump enables automated flushing of an administration set loaded in the enteral feeding pump. The docking station may have a valve seat configured to receive a switchable flow valve of the administration set, a flush controller, an actuator connected to the flush controller and configured to releasably mate with the switchable flow valve when the switchable flow valve is received by the valve seat, and data communication means by which data signals sent by the enteral feeding pump are inputted to the flush controller of the docking station when the enteral feeding pump is connected to the docking station. In operation, the flush controller may receive a flush command sent by the enteral feeding pump and transmit a control signal to the actuator for switching the switchable flow valve to a flush position in response to the flush command.
