The present application discloses a system for monitoring blood pressure. The system comprises a blood pressure cuff including a connector having an identifier associated with a blood pressure cuff size and a blood pressure measurement device comprising an emitter and a detector, the detector operatively connected to a processor. When the blood pressure cuff connector is mated with the measurement device, the emitter is positioned to direct radiation at the identifier and the detector is positioned to receive radiation from the identifier and generate a signal. The processor then determines the blood pressure cuff size based on the signal received from the detector.

A radio frequency identification tag including a stretchable substrate (105) and an antenna (110) having a plurality of substantially concentric loops (140) disposed on the substrate is described. A radius of curvature of the antenna along at least 90% of each loop of the antenna may be greater than about 0.1 mm and less than about 5 mm. The antenna includes a first terminal (124) disposed within an innermost loop (145) of the antenna and a second terminal (126) disposed outside an outermost loop (147) of the antenna (110). The first terminal (124) is in electrical communication with a first end (120) of the antenna and the second terminal (126) is in electrical communication with a second end (122) of the antenna. The radio frequency identification tag may include an electrode making electrical connections with the first and second terminals.

Also, the present invention relates to a mouthpiece for such medical device and a method and a system for monitoring a physiological pulmonary condition.
摘要:
The present disclosure provides methods and apparatuses for providing an audible feedback based on a proximity or a link quality between an external reader and a tag. The external reader transmits power to the tag with a radio frequency electromagnetic signal. The tag may rectify the radio frequency electromagnetic signal and create a rectified voltage. This rectified voltage may be used to power various components of the tag. Once it receives power from the reader, the tag may communicate information back to the external reader. The information communicated back to the reader is communicated by modulating an antenna impedance of the tag. By modulating the impedance, the tag will backscatter radiation transmitted by the reader. The reader is able to create an audio output based on determining the proximity or link quality from the reader to the tag based on the backscatter radiation it receives from the tag.

A biopsy sampler comprising a penetration zone for receiving a part of an organism to be sampled, a ram situated at a first side of the penetration zone able to be actuated to move along a path between a withdrawn position and an advanced position, a sample collector that can cut a biopsy sample from tissue interposed in the penetration zone, and a container that can receive the sample collector, the sample collector and the container being initially located on opposite sides of the penetration zone, a disposable shield initially located between the ram (with the ram in the withdrawn position) and the penetration zone, advance action of the ram from the withdrawn to the advanced position bringing together the sample collector and container at side of the penetration zone away from the ram, and bringing the disposable shield into the penetration zone, withdrawal action of the ram from the advanced position to the withdrawn position withdrawing the disposable shield to the first side of the penetration zone, leaving the tissue free to leave the penetration zone, such that in use in collecting a sample the shield contacts tissue surfaces and the ram does not contact tissue surfaces.
摘要:
A restraint device (10) includes at least one sensor (26) configured to sense at least one parameter associated with the wearer of the restraint device (10). The sensed parameter may be a physiological parameter of the wearer, or the sensed parameter may be a biological substance, a chemical substance, or a radioactive substance, for example. The restraint device (10) may further include a device (28) communicating with the sensor (26) and configured to store and/or transmit information related to the sensed parameter via Radio Frequency Identification (RFID) communication.
