Abstract: An oximeter has a housing configured to have a cavity defining portion that is adapted to be fitted with covers of various dimensions to effect receptacles of different dimensions for accommodating differently sized sensor of sensor assemblies that are matable to the oximeter for sensing physical attributes of a patient. Each of the covers, once fully fitted to the housing, is fixedly latched thereto unless a force that overcomes the latching is applied to remove the cover. The effected receptacle is adapted to biasedly retain a corresponding sensor placed therein. The holstered sensor therefore would not accidentally fall out or be removed from the receptacle, until the user deliberately applies a force to remove the sensor from the receptacle.

Abstract: A wireless network having an architecture that resembles a peer-to-peer network has two types of nodes, a first sender type node and a second receiver/relay type node. The network may be used in a medical instrumentation environment whereby the first type node may be wireless devices that could monitor physical parameters of a patient such as for example wireless oximeters. The second type node are mobile wireless communicators that are adapted to receive the data from the wireless devices if they are within the transmission range of the wireless devices. After an aggregation process involving the received data, each of the node communicators broadcasts or disseminates its most up to date data onto the network. Any other relay communicator node in the network that is within the broadcast range of a broadcasting communicator node would receive the up to date data.

Abstract: A single use, self-contained, self-powered disposable oximeter, in the form of a patch or a bandage strip, has mounted thereto a light emitter and a light sensor that together measure at least the SpO2 of the patient. Mounted to an electronics layer of the patch is an application specific integrated circuit (ASIC) that has electronics integrated thereto that controls the operation of the light emitter and light sensor, and the algorithm for calculating from the data collected by the sensor at least the SpO2 of the patient. Optionally, a display and an alarm may also be mounted or embedded onto the patch for respectively displaying at least the SpO2, and for informing the caregiver/patient that at least the SpO2 is not within an acceptable range, if such is the case. Also provided in the patch is a battery that powers the operation of the ASIC circuit and the emitter, as well as the display and alarm if such optional components are provided on the patch. An attachment mechanism is also provided on the patch.

Abstract: A device such as for example a electronic medical device has a memory that has prestored therein a number of programs or routines for performing various functions. Some of those functions are optional functions that were not enabled when the equipment was put into service. If the user of the equipment desires thereafter to activate any one of those optional functions, an options card that has a number of memory blocks each specifically configured to enable one of the prestored optional functions is sent to the user. The user can then insert the options card into a receptacle integrated into the device and, upon power up of the device, elect a menu for enabling the desired optional function(s) prestored in the device. The options card may be configured to have a count number that indicates the number of devices the card may be used for enabling a particular optional function.

Abstract: A detector that monitors the presence of halogenated agents and the presence of N2O includes a base to which a filter cannister is removably coupled. The cannister has an input for accepting exhalent from a patient or an anesthesia machine and an outlet for outputting the filtered exhalent as gases to the base. The filtered gases are routed a gas measurement or monitor cell housed in the base. The cell has a halogenated agents sensing system and a N2O sensing system. When the filter material in the filter cannister could no longer filter out the halogenated agents, the agents are passed from the filter to the measuring cell, which would detect the presence of the halogenated agents. An audible alarm sounds when halogenated agents are detected. This tells the user that it is time to replace the filter cannister.
