Techniques for monitoring intraperitoneal volume (IPV) during a dwell period of a peritoneal dialysis patient include monitoring intraperitoneal pressure (IPP) during the dwell period using a pressure sensor, monitoring the density of the dialysate during the dwell period, and determining a change in IPV based at least on a change in IPP and a change in the density of the dialysate during the dwell period.

An inhaler includes a mouth-piece 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.

An apparatus and method of controlling the delivery of therapeutic gas delivered to a patient undergoing positive airway pressure therapy is described. The method includes providing a flow of gas to a patient's airway at a pressure, obtaining information from the range of 0 to 25 Hz of the frequency domain of the flow, and adjusting the pressure based on the information. The apparatus includes a blower for providing a flow of gas to a patient's airway at a pressure, a sensor to measure a characteristic of the flow, a controller to obtain information from the range of 0 to 25 Hz of the frequency domain of the characteristic, and a pressure regulator for adjusting the pressure based on the information.

A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

The invention relates to a medical drug delivery apparatus which comprises a cartridge (1) being closed at one end by a membrane (12) and at the opposite end by a movable piston (15). A piston rod foot (1) is provided for transferring the pressure from the piston rod (20) of the drug delivery apparatus and onto the piston (15). The piston rod foot (1) comprises a center part (2) abutting the piston rod (20) and an outer part (3) which center part (2) and outer part (3) are coupled together such that the two (2, 3) can be moved relative to one another, yet remain coupled to each other, when a force above a certain threshold limit is applied to the outer part (3).

The invention refers to a device for attachment to a portable liquid injection device, wherein said device is designed to enclose the drug reservoir of the injection device completely. Further, said device has at least two flat conductive electrodes enabling an electrical field to be applied across the entire volume of the drug reservoir of the injection device. In particular, the portable liquid injection device is a so-called insulin pen, i.e. a portable liquid injection device which is used to inject insulin for the treatment of diabetes. The inventive device preferably is in the form of a cap, in particular in the form of a cap of an insulin pen.

The techniques described herein relate to computerized methods and systems of at least one of for generating a single light indication pattern via LEDs for a dose detection system, such as for example, based on a use case type and a battery life status type. The use case types may include pairing, manual synching, and/or dose injection, and the battery life status types may include 1 to 3 different states. Another method and system are for reducing drainage of a battery for a dose detection system by monitoring the continuous activation of the power-on module, and/or alerting the user in a manner for the user to take action. At least some of the information obtained from these techniques may be communicated to a paired remote electronic device, such as a user's smartphone.

A system is provided for dispensing a fluid. The system has a housing having a fixation means to a user and an orientation element; the cartridge formed so as to be held in a given orientation by the orientation element with respect to the housing; and control means to activate the cartridge to eject a fluid. In one aspect, the system is a emergency rescue fluid(s) transdermal delivery system which includes a removable, single use emergency rescue fluid(s) dispensing cartridge, a wearable device into which the emergency rescue fluid(s) dispensing cartridge uniquely, matingly and removably inserts. The system includes a communication pathway between the wearable device and at least one other cloud network node, and/or at least one communication pathway between the wearable device and at least one GPS network node. In another aspect, the system dispenses a perfume or other fragrance.

An improved medicant delivery system is disclosed wherein the carrier for the medicant is a fluid that can be atomized or vaporized by exposure to heat. The system provides for repeatable dose of medicant, can be stored in any orientation, and/or has an ability to maximize energy efficiency.

A fluid management system including a pass-through fluid volume measurement system to provide continuous measurement of fluid returned from a surgical site during transit to a waste collection system. The pass-through fluid volume measurement system eliminates the need to physically replace full fluid collection containers during the medical procedure with new, empty fluid collection containers.
