The present invention connects to tubing through which gas flows to a patient. An alert notifies monitoring personnel that oxygen flow to the patient has been interrupted, because the tubing has been disconnected. The invention comprises an adapter that is connected to a gas or oxygen source and a nipple over which the tubing fits and through which oxygen flows to the patient. When the tubing becomes disconnected from the nipple, the oxygen flow actuates an alert. In one embodiment, the invention includes a spring and swing arm that, when the tubing becomes disconnected from the nipple, align the nipple with a swing arm so that the gas flows through the nipple and the swing arm to actuate the alert.

An aerosol provision system comprises a heating element for generating an aerosol from a source liquid and control circuitry for controlling a supply of electrical power from a power supply to the heating element. The control circuitry is configured to measure an indication of a derivative of an electrical characteristic of the heating element with respect to time. Based on the measured time derivative, the control circuitry is configured to determine whether or not a fault condition has arisen for the electronic aerosol provision system. The overall change in the electrical characteristic for the heating element caused by the localized heating may be small and so difficult to reliably identify, but the rate at which the change occurs can be expected to be relatively high, such that the time derivative of the local characteristic is a more reliable indicator of occurrence of the fault condition.

An anesthetic administration device comprising an infusion device, which is in fluid connection with a regional anesthetic needle by means of a feed tube. The infusion device comprises one or more anesthetic flow devices capable of triggering forward flow, and optionally backward flow, of the local anesthetic through the regional anesthetic needle. Forward, and optionally backward flow, of the local anesthetic through the regional anesthetic needle is controlled by a controller that comprises one or more actuator switches. The one or more actuator switches are positioned on the device 1 such that they may be operated by hand.

A system for priming an infusion pump is disclosed. The system includes a priming cap including a septum and configured to matably connect with a male part comprising a needle and attached to a length of tubing for fluid, wherein when matably connected with the male part, the priming cap occludes the tubing.

Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, incorrect connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if reverse flow conditions or other error conditions exist. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The methods can be implemented at the humidifier side, at the gases source side, or both.

An insertion mechanism for a drug pump includes an insertion mechanism housing; a sleeve; a rotational biasing member initially held in an energized state; a retraction biasing member and a hub connected to a proximal end of a needle, wherein the retraction biasing member is held initially in an energized state between the hub and the sleeve. The needle is inserted into a target tissue by the rotational biasing member and interaction between the hub and housing. Retraction of the needle is caused by decompressing or de-energizing of the retraction biasing member. A drug delivery pump includes an activation mechanism, a drive mechanism, a sterile access connection, and the insertion mechanism. Assembly and operation methods are provided.

An anesthetized catheter that includes the ability to administer substances and remove substances via the catheter orifice as well as pericatheter with the option of using wireless technology, while also having an indication system.

According to an aspect, there is provided a training device for use in an inhaler, the training device comprising a body that is configured to be received at a first position in a housing of an inhaler, wherein the body comprises an interface arranged to connect to a canister interface in the housing of the inhaler; an electrical circuit configured to perform one or more functions; and a circuit triggering mechanism that comprises a switch for enabling the electrical circuit to perform the one or more functions when the switch is closed, wherein the circuit triggering mechanism is configured such that the switch is closed when the body is pressed from the first position towards the canister interface and into a second position in the housing of the inhaler.

Described are gas flow disruption alarms. The alarms can include a gas inlet; a gas outlet configured to couple to a gas delivery device; and a vibration member between the gas inlet and the gas outlet configured to produce an audible sound when a gas delivery device is removed from the gas outlet.

A patient care system has a medical pump for delivering a medicine to a patient, and a processor in communication with the pump. The pump is configured to receive a first input on whether the medicine is a critical medicine, and a second input on a trigger condition that triggers a fail-operate mode for the critical medicine. The processor controls the medical pump to operate in the fail-operate mode, where the fail-operate mode continues delivery of the critical medicine when the trigger condition is triggered.
