A system to detect occlusion of an intravenous catheter may include a housing, which may include a distal end configured to couple to a proximal end of a catheter adapter and an inner lumen forming a fluid pathway. The system may also include a wave transmitter, a transducer disposed within the fluid pathway, a processor coupled to the transducer, and an indicator unit coupled to the processor. The wave transmitter may transmit energy waves along a length of an intravenous catheter of the catheter adapter. The processor may receive an electrical signal corresponding to the portion of the energy waves that are reflected back from the intravenous catheter and may determine a difference between the electrical signal and a baseline signal. In response to the difference between the electrical signal and the baseline signal meeting a threshold value, the indicator unit may alert a user.

Techniques related to advance diagnosis of operating mode viability are disclosed. The techniques may involve obtaining status information pertaining to operation of a fluid delivery device. The status information may include at least one of a group comprising recent sensor measurement data, sensor calibration data, blood glucose reference measurement data, fluid delivery data, a current battery level of the fluid delivery device, and a current amount of fluid remaining in the fluid delivery device. The techniques may further involve determining, based on the status information, viability of transitioning to a destination operating mode of the fluid delivery device. Additionally, the techniques may involve causing generation of one or more user notifications of recommended remedial actions to improve the viability of transitioning to the destination operating mode when transitioning into the destination operating mode is determined not to be viable.

Devices, kits and methods for determining the site of intramuscular injection in adult and child patients are disclosed. The device includes a top element and two legs that are configured to be fastened in a first position and a second position. When placed in the first position and second position, the device forms a substantially triangular region having a center that corresponds to the site of injection.

The disclosure refers to an apparatus, including a needle unit including a needle arranged along a first axis, a needle shield which covers the needle, a main part, a connector for connecting the needle shield to the main part by a positive connection or an adhesive bond, such that the needle shield is removed when the main part is moved along the first axis away from the needle.

An inhaler includes a mouthpiece cover, a pressure sensor, a first indicator and a second indicator. The first indicator may be configured to indicate based on a state of the cover, and the second indicator may be configured to indicate based on an output of the pressure sensor. For example, when the mouthpiece cover opens, the first indicator may illuminate and a dose of medication may be transferred from a reservoir to a dosing cup. The second indicator may illuminate if an amount of inhaled medication reaches a predetermined threshold for successful inhalation.

Disclosed is a ratchet mechanism having ratchet ring and a chassis. The ratchet ring is rotatable about an axis relative to the chassis, with a general direction of rotation determined by teeth of the ratchet mechanism. The ratchet ring has a first set of teeth arranged regularly around the ratchet ring and protruding in a first axial direction from the ratchet ring and a second set of teeth arranged regularly around the ratchet ring and protruding in a second opposite axial direction from the ratchet ring. The chassis has a third set of teeth arranged regularly and protruding in the second axial direction and generally opposed to the first set of teeth, and a fourth set of teeth arranged regularly and protruding in the first axial direction and generally opposed to the second set of teeth.

Techniques disclosed herein relate to managing transitions into fluid delivery device operating modes. In some embodiments, the techniques involve obtaining status information pertaining to operation of a fluid delivery device, the status information including fluid delivery data, exiting a closed-loop operating mode of the fluid delivery device based on the status information, and, after exiting the closed-loop operating mode, causing generation of a user notification recommending a remedial action to improve viability of a subsequent instance of the closed-loop operating mode. The closed-loop operating mode is an operating mode in which dosage commands are automatically generated based on sensor measurement data.

The disclosure relates to a medicament delivery device, comprising a medicament cartridge adapted to contain a medicament and a stopper slidably arranged within the cartridge. The stopper-comprises a rigid body that is enclosed partially by a soft sealing component.

A process and apparatus monitor a ventilator (100). The ventilator (100) performs supportive artificial ventilation including a sequence of ventilation strokes, with the objective that each inspiration effort of the patient (Pt) triggers a ventilation stroke and the start and the end of the ventilation stroke coincide with the start and the end of the inspiration effort, respectively. A monitoring unit (11) detects deviations between the patient's own inspiratory efforts and the artificial ventilation and determines a respective measure for the respective frequency and/or duration for different possible asynchrony types.

An administration system for delivery of a pharmaceutical composition to a patient has a delivery device configured to deliver a dose of the pharmaceutical composition to the patient and a notification device in communication with the delivery device. The notification device is configured to communicate information about a status of at least one property of the delivery device. The delivery device can be a wearable automatic injector configured to be worn on the patient's skin. The delivery device of the present disclosure may allow a user or the patient to view a status of a container. For example, the delivery device of the present disclosure may provide a simple and effective visual means of displaying fill confirmation and delivery confirmation.
