摘要:
A testing apparatus and method for characterizing the aerodynamic particle size of an atomized medicament emitted from a metered dose inhaler unit during testing with a particle characterization device in which the testing apparatus includes a first clamp of a first fixture in removable clamping and locking engagement with a throat, which is in fluid communication with a particle characterization device, a second clamp in removable clamping and locking engagement with a delivery device of the metered dose inhaler unit having a canister, containing atomized medicament, operatively loaded therein, an alignment mechanism that removably couples the first fixture to the second fixture at an aligned position therefore causing the throat to be in fluid communication with the delivery device, and an actuation assembly mounted to the first fixture having means that operatively thrusts the canister into the delivery device of the metered dose inhaler unit, thus releasing atomized medicament .
摘要:
A bubble detector utilizes an ultrasonic transducer to sample bubbles as they pass the transducer. The envelope of the return signal is analyzed to determine the volume of each sampled bubble. If the total volume of bubbles sampled within a certain period of time exceeds a desired maximum volume, the bubble detector may initiate a system shut down. A bubble detector can be evaluated or calibrated by introducing bubbles into a conduit, detecting the bubbles introduced into the conduit using visual inspection or a bubble detector of known resolution and comparing the results with the examination of a bubble detector under evaluation.

Tools for determining, and adjusting the setting of an adjustable valve (10) are disclosed. These tools allow a medical professional to locate, and non-invasively determine the setting of an implanted valve (10). After the valve (10) has been located, and the setting of the valve determined, the valve may be re-adjusted non-invasively. There are three tools, a locator tool (26), an indicator tool (28), and an adjustment tool (30). The locator tool (26) allows the physician to locate the adjustable valve (10) of interest, and align the locator tool (26) with a specific orientation of the valve (10). The indicator tool (28) indicates the current setting of the adjustable valve (10), and confirms new settings of the valve (10) after the new settings have been implemented. The adjustment tool (30) interacts magnetically with the implanted adjustable valve (10) to couple with a movable internal element to change the setting of the valve. The indicator tool (28), and the adjustment tool (30) physically cooperate with the locator tool (26)to accomplish the respective function of the tools.
摘要:
An infusion monitoring device including a programming console (10) with a data input unit (20) for inputting infusion parameters, a calculating unit for preconditioning the parameters, and an output interface for said parameters. The programming console (10) may be used to program a large number of self-contained monitoring units (12, 12') each having a sensor (14) combined with a drop counting ampoule for sensing the presence or absence of a drop. Each monitoring unit (12, 12') has a housing for a timing and counting unit, a display unit, an alarm unit, a self-contained power supply, an input interface for receiving parameters preconditioned in the programming console, a memory unit for storing the parameters, and a separate calculating unit for controlling the counting/timing, the display and the alarms.

摘要:
An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.

An electronic smoking article includes a liquid supply including liquid material, a heater operable to heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol, a wick in communication with the liquid material and in communication with the heater such that the wick delivers the liquid material to the heater, at least one air inlet operable to deliver air to a central air passage upstream of the heater, and a mouth end insert having at least two diverging outlets.
摘要:
A base module (1,1') for controlling infusion pumps (14,3) is connected with at least one infusion pump for infusing liquids, in particular into a circulatory system of a patient. Therein, a plurality of module connectors (10) is provided, via each of which the base module (1, 1') is connectable with an external control module (2), wherein each of the module connectors (10) provides a module interface, wherein the base module (1, 1') is adapted to receive control information from a control module (2) via the module interface provided by the module connector (10) the control module (2) is connected to and to control at least one infusion pump (14,3) connected with the base module (1, 1') in dependence on the received control information, which derives from patient parameter sensors (25) connected to the respective control modules. In this way a base module is provided which allows to perform a plurality of infusion control functions via different connected control modules. A communication test method between control and base module is also disclosed.
摘要:
Device (1) for checking the distribution (2) of fluid (3a, 3b) ejected from a nebulizing dispenser (4) of fluid (3a, 3b), of the type comprising a discharging nozzle (4b) of nebulized fluid; the device comprising detecting means (5) for detecting the temperature difference between at least part of the nebulized fluid (3b) ejected from the dispenser (4) and at least one contrast space (7), and/or the temperature difference caused by the nebulized fluid (3b) ejected from the dispenser (4) to the contrast space (7). In this case, the contrast space is arranged so as to be at least partially incident to said nebulized fluid (3b).
