An optical decoding system including an optical sensor integral with or attachable to a housing of a drug delivery device and configured to be directed at first and second rotatable components of a dose setting and dispensing mechanism of the drug delivery device and a processor configured to: (i) cause the optical sensor to capture images of the first and second rotatable components at least at the beginning and end of a medicament dose dispensing process; (ii) determine a rotational position of both the first and second rotatable components in each of the captured images; and (iii) determine from the rotational positions of the first and second rotatable components an amount of medicament delivered by the dose setting and dispensing mechanism of the drug delivery device.

This document provides systems and methods that can improve the efficacy of tube and needle thoracostomy. For example, this document provides devices and methods for confirming the proper placement of a chest tube or needle within the pleural space to relieve a pneumothorax or tension pneumothoax.

An applicator can include a dispenser for dispensing an amount of a therapeutic composition, which can include an amount of sugar or sugar alcohol and an amount of an alkalizing agent. In some cases, the alkalizing agent can include L-Arginine. In some cases, 75% or more of the composition by weight has a comedogenicity rating of 3 or less on a scale of 0-5. The dispenser can also have a power supply configured to provide power through a contact tip of the dispenser to provide nerve stimulation, such as using vibration, heating, cooling, and/or electrical stimulation.

A clamping module of or for a medical pump, and a method for identifying a hose clamp of a disposable infusion article insertable into the clamping module. The clamping module includes an electro-optical system for identifying the hose clamp, which has an optical marking. The electro-optical system includes a first light source for emitting at least a first light beam and a second light source for emitting at least a second light beam. The second light source is formed differently than the first light source. A photodetector receives a reflected light, and an optical window bundles the first light beam and/or the second light beam on the disposable infusion article, as well as the reflected light received by the photodetector. The method identifies the hose clamp based on a color and uses a measurement algorithm after insertion of the hose clamp into the medical pump.

Systems and methods for fluid delivery into a ventilation system are disclosed. In an example, the technology relates to a fluid delivery system for delivery of aerosolized liquid. The fluid delivery system includes an injection tip having a set of orifices configured to aerosolize a liquid having certain properties. The injection tip may be couplable with components of a breathing circuit. For example, the injection tip may be couplable with components at or below a wye component (e.g., at a wye component or between the wye component and a patient), such as at the wye component or at an endotracheal tube multi-port connector. Alternatively, the injection tip may be integrated into a breathing circuit, such as at an endotracheal tube connector or at an endotracheal tube.

Disclosed is a method and an auto-injector for administering a medicament. The auto injector comprising: a housing; a cartridge receiver configured to receive a cartridge comprising a first stopper; a drive module coupled to move a plunger rod between a retracted plunger rod position and an extended plunger rod position, the plunger rod being configured to move the first stopper; a resistance sensor configured to provide a resistance signal indicative of resistance against movement of the plunger rod; and a processing unit coupled to the drive module and to the resistance sensor. The processing unit being configured to: control the drive module to move the plunger rod towards the extended plunger rod position with a plunger rod speed; determine plunger rod position; receive the resistance signal; and control the drive module to adjust movement of the plunger rod if the resistance signal is indicative of resistance against movement of the plunger rod above a high resistance threshold, wherein the high resistance threshold is based on the plunger rod position.

The present invention concerns an apparatus (1) for measuring and recording the remaining quantity of medicament in a medicament dosing device (2). The apparatus (1) has a location where the medicament dosing device (2) can be inserted. Combined with that location the apparatus (1) has equipment for measuring and analysing. The apparatus is characterised in that this equipment for measuring and analysing comprises a contact image sensor (3) combined with that location for the medicament dosing device, and a software in connection with the contact image sensor. In addition the object of this invention is the corresponding method for measuring and recording the remaining quantity of medicament in a medicament dosing device (2).

A system comprising a biopsy needle device comprising a cannula comprising a distal end configured to sever a tissue sample, and a trocar disposed within the cannula comprising a notch configured to retain a tissue sample, wherein at least one of the cannula and the trocar is divided into at least two segments including different echogenic coatings, an ultrasound probe, and a processor configured and arranged to collect images from the ultrasound probe and color code the at least two segments based on at least one characteristic relating to different echogenic coatings, surface textures, surface contours and dimensions of the biopsy device.

A plurality of first sensory cues are generated capable of being perceived by a user. Each first sensory cue of the plurality of first sensory cues is dependent on a position of at least one body member of a performer relative to a performance element of a performance object with which an event is performed. The plurality of first sensory cues being effective for stimulating a first processing center of a brain of the user. A plurality of visual sensory cues are generated capable of being displayed to the user on a video display device. The visual sensory cues providing a virtual visual indication to the user of the position of the at least one body member. The visual sensory cues being effective for stimulating the visual processing center of the brain of the user. The visual sensory cues being synchronized with the first sensory cues so that the position of the at least one body member is virtually visually indicated in synchronization with the first sensory cue and so that the visual processing center is stimulated with a visual sensory cue in synchronization with a first sensory cue stimulating the first processing center. The synchronized stimulation of the first processing center and the visual processing center is effective for teaching the user to perform a version of the event.

A medication delivery device included molded cylindrical barrel having visual marks on the surface of the barrel in the axial direction, a plunger seals the distal opening of the cylindrical barrel, a molded needle hub disposed in the proximal opening of the cylindrical barrel for sealing the needle hub to the barrel. A needle is disposed in the needle hub for communicating liquids by operation of the plunger in the axial direction. The circumferential surface on the flange of the needle hub comprises a colored mark that corresponds to a characteristic of the medication delivery device or its contents.
