11660412 · 2023-05-30 ·

Disclosed embodiments of an endotracheal tube (ETT) guard system help to hinder self-extubation of the ETT of an awake patient who may reflexively attempt removal, but also allow early mobilization and exercise necessary for preservation of muscle strength. Embodiments may include an ETT holder, which may be generic ETT holders offered by various medical device companies, or a specially configured ETT holder as described herein. Embodiments also may include a sensor that alarms when the ETT guard is moved beyond pre-set motion thresholds.

20230158256 · 2023-05-25 ·

An inhaler configured and adapted for inhaling an inhalation medium, enriched with active ingredients and/or flavouring substances, includes a cartridge carrier, a storage tank which contains the inhalation medium, a mouthpiece which is associated with the cartridge carrier, and an actuating mechanism for releasing the inhalation medium out of the storage tank in the direction of the mouthpiece. The inhaler has at least one sensor associated with the mouthpiece. The sensor is configured and adapted to detect characteristics of lips of the person using the inhaler and to provide a data signal formed from the characteristics. The sensor is connected to an electronic control unit associated with the inhaler, to which the actuating mechanism is also connected, in such a manner that the inhalation medium is released on the basis of the data signal. A corresponding arrangement and a corresponding method are disclosed.

An apparatus for treatment of a respiratory condition, the apparatus comprising: a pressure generator configured to generate a flow of breathable gas; an intermediate component pneumatically connected to an air delivery tube, the intermediate component comprising a port configured to facilitate propagation of sound outside of the intermediate component; a sensor attached externally to the intermediate component and located adjacent to the port of the intermediate component, the sensor configured to sense sound propagated through the air delivery tube; and a controller. The controller can be configured to: receive a sound signal generated by the sensor as a result of sensing sound during operation of the apparatus, analyse the received sound signal, and effect a response based at least in part on the analysing.

Dialysis system having inductive heating

A dialysis fluid system includes a dialysis fluid inlet; a dialysis fluid outlet; a pump positioned and arranged to pump dialysis fluid through the dialysis fluid inlet and the dialysis fluid outlet; and an inductive heater located between the dialysis fluid inlet and the dialysis fluid outlet, the inductive heater including a fluid flowpath positioned and arranged to receive non-heated dialysis fluid from the dialysis fluid inlet and to output heated dialysis fluid to the a dialysis fluid outlet, a conductive heater element located within the fluid flowpath so as to be or act as a secondary coil of a transformer, and a primary coil of the transformer located outside of the fluid flowpath and positioned so as to magnetically induce a current into the conductive heater element, causing the conductive heater element and surrounding fluid to heat.

System and Method For Utilization of Data From Remote Regulation and Monitoring of Drug Delivery

Aspects and embodiments of the present invention generally include a device for patient self-administration of a prescribed medication. The device makes available for administration the precise quantity of medication constituting a dose at times designated by a health care provider (HCP). Preferably, the device also detects and transmits information to a remote management system accessible to the HCP, including detected attempts to tamper with the device. Advantageously, HCPs may render oversight and control over the device and its use to mitigate risks associated with patients self-administering medication without in-person supervision. This control may include establishing prerequisites the patient must meet prior to a dose being made available, or remote deactivation of the device. This oversight by the HCP may include patient-specific and aggregate data analysis for optimization of treatment or evaluation of the safety and efficacy of a treatment. Furthermore, this oversight may be conducted via a web-based interface.
