A system and method to help maintain quality control and reduce cannibalization of accessories and attached probes in a highly sensitive patient monitor, such as a pulse oximetry system. One or more attached components may have information elements designed to designate what quality control mechanisms a patient monitor should look to find on that or another component or designate other components with which the one component may properly work. In a further embodiment, such information elements may also include data indicating the appropriate life of the component.

An analyte sensor device includes a housing, a sensor, and a printed circuit board assembly (PCBA) within the housing and including a circuit and a first plurality of contacts. The sensor includes a proximal end within the housing and a distal end outside of the housing. The proximal end includes a second plurality of contacts electrically connected to the first plurality of contacts on the PCBA. The distal end includes one or more electrodes configured to measure a concentration level of an analyte in a body of a user. The circuit is operable to detect electrical connection between the first plurality of contacts and the second plurality of contacts within the housing while the distal end of the sensor is outside the body of the user or a fluid.

An ECG controller for an ECG device is connectable to a base ECG lead system (e.g., a 12-lead system) whereby the ECG controller implements an ECG waveform morphology based and ECG lead redundancy based detection and classification of any cable interchange (e.g., a limb cable interchange or a precordial cable interchange) between the ECG controller and the base ECG lead system. Alternatively, the ECG controller is further connectable to a sub-base ECG lead system (e.g., a limb only-lead system or a limited precordial-lead system) whereby the ECG controller implements an ECG waveform morphology based detection and classification of any cable interchange (e.g., a limb cable interchange or a precordial cable interchange) between the electrode interface and the sub-base ECG lead system.

An electrode assembly for patient monitoring and treatment can include an electrode configured to be worn by a patient to provide at least one of monitoring a cardiac function of the patient and delivering a treatment for cardiac arrhythmia to the patient; and a first connector connected to and in communication with the electrode, the first connector including a male connection portion. The male connection portion is configured to engage a second connector to form a mating engagement between the first connector and the second connector. The male connection portion includes at least one orientation aligning feature configured to engage the male connection portion of the first connector with the second connector in a fixed orientation with respect to the second connector to form the mating engagement. The first connector has a flattened profile.

A physiological signal monitoring device includes a base including a base body that has a bottom plate and an opening, a biosensor mounted to the base, and a transmitter removably mounted to the base body. The base further includes a first coupling structure disposed on a top surface of the bottom plate, and the transmitter includes a second coupling structure coupled to the first coupling structure when the transmitter is mounted to the base body. When the first and second coupling structures are coupled to each other, they are disposed to be distal from a periphery cooperatively defined by the base and the transmitter. They are uncoupled from each other when an external force is applied through the opening of the base body to separate the transmitter from the base.

A medical visualisation system including a first medical visualisation device having a first device colour identifier, a second medical visualisation device having a second device colour identifier, a third medical visualisation device having a third device colour identifier, and a monitor device, the first device colour identifier being a first colour, the second device colour identifier being a second colour, and the third device colour identifier being a third colour. The first colour has a first hue angle, the second colour has a second hue angle, and the third colour has a third hue angle, wherein the first hue angle and the second hue angle differ by more than 40 degrees, the second hue angle and the third hue angle differ by more than 40 degrees, and the third hue angle and the first hue angle differ by more than 40 degrees.

One aspect of the present disclosure involves a method. The method includes retrieving, from a diagnostic medical device, identification information that identifies a feature of the diagnostic medical device. A proprietary signal is generated in response to the identification information. The proprietary signal is sent to a medical measurement system to facilitate an unlocking of one or more programs to be executed on the medical measurement system. Another aspect of the present disclosure involves a method. The method includes detecting, through an electronic interface device, a coupling of a remote diagnostic medical device. Thereafter, a proprietary signal is received from the electronic interface device. An identity feature of the remote diagnostic medical device is ascertained based on the proprietary signal. One or more programs are unlocked for execution if the identity feature of the remote diagnostic medical device matches a predetermined identity feature.

An electronic apparatus includes: a connector which is configured to enable one of measurement devices for measuring different types of bio signals to be selectively attached thereto or detached therefrom; a communication device configured to communicate with an external apparatus; and a processor configured to, in response to the measurement device being attached to the connector, obtain identification information of the attached measurement device and transmit the identification information to the external apparatus, and control the attached measurement device based on a control command received from the external apparatus.

A device is configured to monitor the integrity of a connection system between first and second fluid containing systems comprising first and second pulse generators. A pressure sensor is arranged in the first fluid containing system to detect first pulses originating from the first pulse generator and second pulses originating from the second pulse generator. The device operates a monitoring method, by generating (42) a time-dependent pressure signal based on measurement data obtained from the pressure sensor such that the pressure signal contains a sequence of apparent pulses. The apparent pulses represent a superposition of the second pulses on the first pulses when the connection system (C) is intact. The device processes (44) the pressure signal to calculate a parameter value based on a pulse feature of at least one of the apparent pulses in the pressure signal. The parameter value represents a disturbance caused by the superposition of the second pulses on the first pulses, and may be given as a measure of statistical dispersion, pulse-to-pulse symmetry, or first pulse similarity. The device determines (45) the integrity of the connection system based at least partly on the parameter value. The first fluid containing system may be an extracorporeal blood circuit, and the second fluid containing system may be a human or animal subject.

A coupling device for releasable connection of a medical or dental handpiece to a drive unit or to a supply tubing for transferring signals, data and/or energy, a drive movement, a working medium and/or light between the handpiece and the drive unit or the supply tubing, having a first coupling element and a second coupling element, wherein one of the two coupling elements is designed as a coupling cavity, into which a coupling protrusion on the other coupling element can be inserted, a positioning element, which is disposed on the first coupling element or the second coupling element and can be inserted into a first recess on the other coupling element in order to position the two coupling elements in a defined angular position about their common axis relative to one another, at least one light source, which is disposed in a second recess on the first or second coupling element and can be coupled to an optical fiber on the other coupling element as well as by at least one transfer element, which is disposed on the first or second coupling element and can be inserted into a third recess on the other coupling element to transfer data, signals and/or energy between the first and second coupling elements.
