Methods and apparatus to reduce deadspace in syringes and other devices with the use of volume displacing members that occupy space within one or more interior spaces of such devices. The volume displacing members are also equipped with one or more internal flow passages that facilitate a flow of a fluid through it. The volume displacing members are also adapted to cooperate with features of the devices that house them to form air-tight and liquid-tight seals that at least partially determine a fluid pathway through the devices.

Provided herein are the safety features for radiopharmaceutical infusion system for treatment or diagnostic purpose, wherein infusion system comprises a controller, a source of radiopharmaceutical including other components. The controller is configured to perform automated quality control steps at the start of the system during daily quality control and ensure that system complies to desired technical attributes prior to administration to patients. The quality control steps comprise calibration, breakthrough testing, checking for unauthorized connection and/or malware in the system, network or other connected devices.

The drip monitoring system comprises a weighing device to measure a carrying weight. The weighing device includes a gravity sensor to sense a motion data of the weighing device. The processing element gathers the carrying weight to compare with an empty weight. The processing element gathers the motion data of the weighing device when the carrying weight is less than the empty weight. The processing element determines whether the weighing device is in a calibration orientation or not according to the motion data. When the weighing device is in the calibration orientation, the processing element controls the weighing device to perform a return to zero calibration process.

In a system, a medical apparatus and a remote control device perform a pairing procedure, in which the remote control device sends an identifier of the remote control device, the medical apparatus sends a time-referenced information, the remote control device receives the time-referenced information and generates a first hash key based on the identifier and the time-referenced information, and the medical apparatus receives the identifier and generates a second hash key based on the identifier and the time-referenced information. The second hash key corresponds to the first hash key, wherein, when the pairing has been successfully completed, the remote control device sends an instruction controlling the medical apparatus based on the first hash key, and the medical apparatus accepts the instruction if the first hash key corresponds to the second hash key.

A system and method for tracking and administering liquid intravenous medications in a hospital, clinic, or patient residence, including recording information onto a short range communication device affixed to a liquid container in a hospital pharmaceutical filling or compounding center, the information including drug information, patient information, and IV administration information, transferring the liquid container to a patient's bedside, programming an infusion course into a bedside IV infusion pump by enabling the pump to read the encoded information on the communication device, and disposing of the liquid container and any residual drug in a smart disposal bin that reads the communication device and weighs the container. The disposal bin may confirm the chemical contents of the container.

A fluid connector assembly. The fluid connector assembly includes a tab portion including a slot; a plug portion slidably connected to the tab portion the plug portion comprising a fluid path and a disc, the disc configured to seat within the slot; a catch feature located on a first end of the tab portion and configured to interact with a reservoir; and a latching feature located on a second end of the tab portion, the latching feature configured to interact and lock onto the reservoir, wherein force applied to the plug portion may overcome a threshold force and unseat the disc from the slot wherein the plug portion moves with respect to the tab portion.

Methods and apparatus provide communications among respiratory therapy device (“TD”), server and intermediary (e.g., a control device (“CTLD”) for the therapy device) to improve security. More secure communication channel(s) may be established using shared secrets derived with different channels. The communications may include transmitting therapy data from TD to server for authentication. The CTLD may receive the data and a nonce from a server. The CTLD receives from the TD a signing key dependent on the nonce and a secret shared by TD and server. The CTLD generates an authorisation code with received therapy data and the key for authentication of the data by the server upon its receipt of the code and data. The server computes (1) a key from the nonce and the secret known to TD, and (2) another authorisation code from received therapy data and the key. Data authentication may involve comparing received and computed codes.

A set of at least two drug delivery devices includes a first drug delivery device and a second drug delivery device, The first and second drug delivery devices each include a first set of mutual members that are identical, and the first drug delivery device and the second drug delivery device each include a second set of distinguishing members that differ. The first drug delivery device includes a first connection device for attaching a first dispensing unit to the first drug delivery device and the second drug delivery device includes second connection device for attaching a second dispensing unit to the second drug delivery device, the first and second connection devices differ from each other so that the second dispensing unit is not attachable to the first connection device and the first dispensing unit is not attachable to the second connection device.

A heating device is provided that creates inhalable aerosol that includes one or more heating elements and a temporary or permanently established cavity formed by a barrier between the heating elements and the external environment that envelops the heating elements to allow the insertion and removal of consumables from the cavity and allows for the replacement of the heating elements in the device.

A reader system for reading information on at least one identification tag associated with a syringe connected to a fluid injector has a detector and a background screen spaced apart from the detector such that at least one of the at least one identification tags is positioned in an optical path between the detector and the background screen when the syringe is connected to the fluid injector. The reader system further has an illumination system configured for illuminating at least a portion of the background screen. The detector is configured for detecting and decoding the at least one identification tag. Methods for reading information on at least one identification tag associated with a syringe are also described.
