摘要:
The invention relates to a system and method for tracking drugs during a transfer and administering process to reduce labeling errors that can occur during that process. The system includes a storage container reader that is configured to read a set of one or more storage-container-associated machine-readable indicia positioned on a container containing a drug. The set of one or more storage-container-associated machine-readable indicia identifies the drug. The system further includes an indicia-generating device that is configured to generate a drug-delivery-container-associated indicia identifying the drug based on the storage-container-associated machine-readable indicia. The set of one or more drug-delivery-container-associated indicia includes a set of one or more drug-delivery-container-associated machine-readable indicia. Optionally the system further includes a drug delivery container reader, wherein the drug delivery container reader is configured to read the set of one or more drug-delivery-container-associated machine-readable indicia. Optionally the system further includes a processing unit that generates an output signal corresponding to the drug based on the set of one or more drug-delivery-container-associated machine-readable indicia. Optionally the system further includes an output device that outputs a user-comprehensible output identifying the drug based on the output signal from the processing unit.

A curved surface input device with normalized capacitive sensing is disclosed. The input device can normalize capacitive sensing through an overlay having a varying thickness, such as an overlay with a curved surface. The capacitive sensing normalization can be implemented in software, hardware or a combination of software and hardware. A software implementation for normalizing capacitive sensing can comprise adjusting the sensitivity of a sensing operation associated with different sensor elements of the input device. A hardware implementation for normalizing capacitive sensing can comprise adjusting a hardware configuration of the input device associated with one or more physical parameters that can influence the capacitive sensitivity of the sensor elements, such as an area of the sensor elements, a distance between the sensor elements and other conductive input device elements (such as a ground plane), and a dielectric constant associated with the overlay.

A method of controlling a gas delivery apparatus including an apparatus controllable variable using an iterative algorithm to deliver a test gas (TG) for non-invasively determining a subject's pulmonary blood flow comprising iteratively generating and evaluating test values of a iterated variable based on an iterative algorithm in order output a test value of the iterated variable that meets a test criterion wherein iterative algorithm is characterized in that it defines a test mathematical relationship between the at least one apparatus controllable variable, the iterated variable and an end tidal concentration of test gas attained by setting the apparatus controllable variable, such that the iterative algorithm is determinative of whether iteration on the test value satisfies a test criterion or iteratively generates a progressively refined test value.
摘要:
A portable life support apparatus (1102) and particularly a respiratory support apparatus adapted to be easily mounted to a stretcher is disclosed. Prior devices that attach onto a stretcher are heavy and cumbersome and obstruct access to the patient. Accordingly, there is a great need for a portable emergency support device that overcomes the weight, size, positioning, and other portability disadvantages. One aspect relates to a portable life support device including at least one ambient gas inlet (14); a conditioned gas outlet (30); an oxygen concentrator (26,28) fluidly connected between the at least one gas inlet and the gas outlet, and a ventilator (44) fluidly connected downstream from the oxygen concentrator. A further aspect is directed to a portable life support apparatus in the form of a portable respiratory support apparatus (1102) capable of exploiting both ambient air and expired gas as oxygen sources, wherein the oxygen generator (20) and ventilator (10) are arranged end to end to provide a longitudinal profile that can thus be compactly secured to a stretcher or other similar emergency transport vehicle.
摘要:
A processor obtains input of a logistically attainable end tidal partial pressure of gas X (PetX[i]T) for one or more respective breaths [i] and input of a prospective computation of an amount of gas X required to be inspired by the subject in an inspired gas to target the PetX[i]T for a respective breath [i] using inputs required to utilize a mass balance relationship, wherein one or more values required to control the amount of gas X in a volume of gas delivered to the subject is output from an expression of the mass balance relationship. The mass balance relationship is expressed in a form which takes into account (prospectively), for a respective breath [i], the amount of gas X in the capillaries surrounding the alveoli and the amount of gas X in the alveoli, optionally based on a model of the lung which accounts for those sub-volumes of gas in the lung which substantially affect the alveolar gas X concentration affecting mass transfer.

Compact input devices formed on flexible substrates are disclosed. The input devices may be formed using three or more conducting layers. By including three or more conducting layers, the diameter of the input device may be minimized. In addition, to improve the flexibility of portions of the input device mounted, some portions of the input device may be made to have fewer layers than other portions of the input device.

摘要:
Described is a method for screening for alterations in exocytosis of a population of cells. The cells are sorted by a FACS machine by assaying for alterations in at least three of the properties selected from the group consisting of light scattering, fluorescent dye uptake, fluorescent dye release, annexin granule binding, surface granule enzyme activity, and the quantity of granule specific proteins. Methods for screening for bioactive agents capable of modulating exocytosis in a cell are also described. The methods provide for reduced background and increased specificity without increasing the time or steps involved in assaying for exocytosis.
