Description

A kind of medical detector

Technical field

The utility model relates to medical instruments field, is specifically related to a kind of medical detector.

Background technology

Because science and technology development and to the continually developing of medical detector, existing medical detector has had more friendly operation interface and more perfect detection performance, and it is universal that medical detector has been obtained in family.Existing medical detector can make things convenient for the patient to detect voluntarily, and can with the data storage that detects in medical detector, can also directly in medical detector, show; Like publication number is the Chinese invention patent of CN1472535A, mainly comprises one-chip computer, timer manager, analog to digital converter, power supervisor, LCD and storer, and it is through after gathering, take a sample, handle test data; To detect data stores; Be further collection, management testing data, analyze the state provides more effective basis for estimation; And can on LCD, directly show, simple and clear.But the processor processes ability in the medical after all appearance a little less than, limited to the processing that detects data, can not stronger foundation be provided for successive treatment, and the finite capacity of its storer, the lot of data storage can not be provided.

The utility model content

The utility model technical matters to be solved provides a kind of external unit connectivity port that has, and can carry out data communication, the direct medical detector that on the PC display, shows test data with PC.

For solving the problems of the technologies described above, a kind of medical detector that the utility model designed comprises Acquisition Circuit, sample circuit, center processor and USB interface, and wherein, Acquisition Circuit is used to gather patient's test data, and exports these data to sample circuit; Sample circuit is used for the test data of Acquisition Circuit input is carried out analytical sampling, the test data after obtaining taking a sample, and the test data after will taking a sample is sent to center processor; Said center processor is used for the test data after the sampling of sample circuit input is stored, and carries out USB HID protocol processes, obtains meeting the test data of USB HID agreement, these data is stored again.Said USB interface can link to each other with PC or other equipment, but in order to handle data, preferably links to each other with PC; This USB interface comprises usb data communicating circuit, USB interface power circuit and USB interface trigger circuit, and usb data communicating circuit and USB interface trigger circuit can substitute with the chip with identity function.Said usb data communicating circuit links to each other with center processor respectively with the USB interface trigger circuit, and said USB interface trigger circuit link to each other with the USB interface power circuit, and said usb data communicating circuit also links to each other with the USB interface power circuit.Described usb data communicating circuit is used to realize the data communication of center processor and PC.The USB interface trigger circuit are used to detect the make-and-break signal of USB interface power circuit and outer PC, and when detecting the connection of USB interface power circuit and outer PC, the USB interface trigger circuit send trigger pip to center processor.The trigger pip of USB interface trigger circuit is to carry out voltage division processing by the power supply that USB interface is exported, and this trigger pip signal when USB inserts and break off overturns; Center processor is waken up from low-power consumption mode, and center processor carries out data communication through usb data communicating circuit and PC, and the test data that will meet USB HID agreement is sent to PC; After PC is discerned it automatically; In display screen, show test data, realize the automatic demonstration of test data, and/or storage automatically.

The described USB interface trigger circuit of such scheme can be stabilivolt circuit or transistor switching circuit.

The described USB interface trigger circuit of such scheme can link to each other with center processor through the interruption input of center processor.When USB interface with after PC is connected, the USB interface trigger circuit send trigger pip through the interruption input of center processor and wake center processor up.

The utility model compared with prior art adopts USB interface that medical detector is linked to each other with outer PC, realizes the transmission of data; And the interruption input of USB interface trigger circuit and center processor is connected; Center processor is waken up from low-power consumption mode; And making center processor carry out data communication through usb data communicating circuit and PC, the test data that will meet USB HID agreement is sent to PC, makes PC drive corresponding computer programs automatically; Test data is shown in display screen, realize the automatic demonstration of test data and/or storage automatically.
