A flow sensor sub-assembly for sensing flow of a fluidic medicament is disclosed. The flow sensor sub-assembly includes a first spring contact and a second spring contact. The spring contacts are secured to a base that has a circuit for conducting an electrical signal to and from the spring contacts to a microprocessor. The first spring contact is in electrical communication with a first piezo element and the second spring contact is in electrical communication with a second piezo element. The first spring contact has a first contact force against the first piezo element and the second spring contact has a second contact force against the second piezo element, and the first and second contact forces are equivalent. A circuit board for interfacing to a flow sensor having a plurality of piezo elements for transmitting a flow signal indicative of flow of fluidic medicament is also disclosed.

The construction of a medical device having a disposable element is disclosed. Detachable elements comprising a body having a retention feature, an electrical contactor, and sensors are also disclosed. Further disclosed are detachable elements comprising a body having a hole and a retention pocket, an electrical contactor, and a printed circuit board assembly (PCB) in contact with the innermost surface of the body that forms the retention pocket. Further disclosed are detachable elements comprising a body having an opening and a printed film comprising conductive elements, where the conductive elements comprise a sensor configured to be aligned with the opening to expose the sensor. Further disclosed are reusable components having matching retention features.

Device with disposable element

A column for removal of a component from a fluid is disclosed. The column has a compartment with a cross sectional area. The compartment contains beads having a diameter. A ligand selected to bind to the component is coupled to the beads. The cross-sectional area and bead diameter are selected to maintain a flow velocity of the fluid within the compartment below a first threshold, thereby reducing leaching of the ligand into the fluid. Also described herein is an adsorbent comprising a ligand that is attached to a substrate by an amine bond, wherein the ligand is resistant to dissociation from the substrate.

Reduced leaching of a ligand

A variety of electrode pad cartridges are described that are suitable for use with a defibrillator. In one aspect the cartridge includes a housing and a tray that carries a pair of defibrillation electrode pads. At least a portion of the tray is slidably received within the cartridge housing such that the electrode pads are received within the housing. The tray is configured to be slidably pulled from the cartridge housing while the housing remains attached to the defibrillator to provide access to the electrode pads to facilitate use of the defibrillator.

A vital-signs patch for a patient monitoring system that includes a housing containing a sensor that makes physiological measurements of a patient, a transmitter, a receiver, a memory, and a processor. The processor periodically takes a measurement from the sensor, converts the measurement to a data record, and stores the data record in the memory. Upon receipt of a signal from another device, the processor retrieves at least a portion of the data record, converts the retrieved portion of the data record to a vital-sign signal, and causes the transmitter to transmit the vital-sign signal to the other device.

System and method for storing and forwarding data from a vital-signs monitor

A vital-signs patch for a patient monitoring system is disclosed. The patch consists of a housing that is configured to be worn on the skin of a patient. The housing contains a radio, one or more sensor interfaces, a processor, and a battery. The processor can selectably turn portions of the processor off and on and selectably turn power off and on to at least a portion of the sensor interfaces and radio. The processor includes a timer that, each time the timer times out, will turn all the parts of the processor on and start a new timing period. When the processor receives a signal, the processor will turn off power to at least a portion of the processor and at least a portion of the sensor interfaces.

Devices and methods for reading multiple types of RFID tags having different frequencies and/or encoding schemes are disclosed. One or more search signals covering a plurality of RFID bands are transmitted. A presence indication of an RFID tag in one of the plurality of RFID bands is detected. An interrogating signal having a carrier frequency tuned to a frequency at which the presence indication is detected is transmitted. A tag response signal comprising tag information associated with the RFID tag is received. A digital response signal based on the tag response signal is digital signal processed to obtain the tag information.

Software-defined multi-mode RFID read devices

A vital-signs monitor patch containing at least two electrodes, a circuit assembly, and a patch body having a chamber in which the circuit assembly is housed. The patch body also contains at least one flexible portion adjacent to the circuit assembly chamber, with at least one electrode attached to the flexible portion. The electrodes are configured for attaching the patch to the skin of a patient.
