A medical stopcock includes a main body having an input port and an output port, a valve body having a handle and a syringe port, with the valve body moveable relative to the main body and defining a valve passageway. The valve body includes a first position where the input port and the output port are in fluid communication via the valve passageway, a second position where the syringe port and the output port are in fluid communication via the valve passageway, and a third position where the syringe port and the input port are in fluid communication via the valve passageway. Rotation of the syringe port is configured to move the valve body relative to the main body.

Syringe actuated stopcock smart-valve

A method for readying a fluid sensor associated with a medical device includes attaching a flow restrictor to a fluid outlet of the fluid sensor. The fluid sensor includes a fluid channel, a fluid inlet at a first end of the fluid channel configured to couple to an outlet of an administrable fluid source, and the fluid outlet at a second end of the fluid channel. Fluid is delivered from the administrable fluid source to the fluid channel through the fluid inlet. A syringe actuation device including a force limiting device may be used to deliver the fluid. The fluid is pressurized in the fluid channel between the fluid inlet and the flow restrictor to wet an interior surface of the fluid channel with the fluid. The flow restrictor is removed from the fluid outlet.

Method and apparatus for wetting internal fluid path surfaces of a fluid port to increase ultrasonic signal transmission

A system may include a flow sensor and a base. The flow sensor may include a flow tube, a sensor configured to characterize at least one attribute of a fluid in the flow tube, and an electrical contact in electrical communication with the sensor. The flow tube may include a fluid inlet at a first end of the flow tube, a fluid outlet at a second end of the flow tube, a fluid injection port between the first and second ends of the flow tube, and a valve configured to control a flow of a fluid in the flow tube. The base may include a processor, an electrical contact in electrical communication with the processor, a short range wireless communication device, and a display. The flow sensor electrical contact may be in electrical communication with the base electrical contact when the flow sensor is connected to the base.

Flow sensor system

A system may include a flow sensor and a base. The flow sensor may be configured to connect to the base. The flow sensor may include a flow tube including a fluid inlet at a first end of the flow tube, a fluid outlet at a second end of the flow tube opposite the first end of the flow tube, and a fluid injection port between the first end and the second end of the flow tube. The base may include a short range wireless communication device including a curved coil antenna.

A reader includes a first antenna, a second antenna spaced apart from the first antenna, an RFID reader circuit, and a processor. The first antenna and the second antenna are connected to the RFID reader circuit. The first antenna is configured to receive a first signal from an RFID tag. The second antenna is configured to receive a second signal from the RFID tag. The processor controls the RFID reader circuit to determine a first value of a signal parameter associated with the RFID tag based on the first signal and a second value of the signal parameter associated with the RFID tag based on the second signal, receives, from the RFID reader circuit, the first value and the second value, and determines, based on the first value and the second value, whether the RFID tag is located between the first antenna and the second antenna.
