摘要:
A pump unit (10) includes a number of pumps (14) each having a port in fluid connection to a combined port (12) of the pump unit. A processing system (16) is connected to each of the pumps (14) for independent actuation of each pump. A user interface (22) allows user actuation of the pump unit according to one or more mode of operation, requiring various different levels of suction or pressure. The processing system (16) determines what number of pumps (14) is required, and selectively actuates pumps in order to generate the required suction or pressure. Particularly preferred applications include breast pumps. Additional aspects of the invention relate to a cyclic pulsed suction profile generated by the device, implementations that detect when a milk extraction set is not properly deployed, and configurations which allow a touch screen to be used as a power-on switch for the device.
摘要:
A system for monitoring a period of use of components includes a number of components each having an integrated or attached NFC tag and a monitoring system. The monitoring system includes a processing system, an NFC reader and an output device for providing information to a user. The monitoring system is configured to read data from an NFC tag of one of said components brought into proximity to said NFC reader and determine whether said component has been previously used. For a previously used component, the monitoring system generates an indication to a user of a period-of-use status. For a component not previously used, the monitoring system stores data indicative of a first date of use of the component. Also disclosed is a system for monitoring the expiration date of perishable goods.
