In addition; Because projecting cell 34 has bigger display size, thereby when physiological parameters such as needs enlarged and displayed electrocardiogram, physiological monitor provided by the invention can intactly demonstrate physiological parameters such as electrocardiogram; Thereby make the observer need not display frame is moved or switched the full details that just can observe physiological parameter; Thereby can grasp whole physiologic informations quickly and easily, and then bring convenience for the analysis of testing result, improve the efficient and the accuracy of medical diagnosis.
In practical application, physiological single processing unit 32 can also be sent to the alarm unit (not shown) with this physiologic information.Alarm unit is used to receive the physiologic information from physiological single processing unit 32, and physiologic information and corresponding setting threshold are compared, if physiologic information surpasses corresponding setting threshold, then gives the alarm to the user.Particularly, alarm unit has the setting threshold that quantity equates with the quantity of physiological single processing module 321, and this setting threshold is corresponding one by one with physiological single processing module 321.During use, alarm unit receives the physiologic information from n physiological single processing module 321, and it is compared with corresponding setting threshold one by one.If there are one or more physiologic informations to surpass corresponding with it setting threshold in the physiologic information that compares, then alarm unit will adopt at least a mode in the modes such as sound, light and vibration to give the alarm to the user.In addition, physiological single processing unit 32 can adopt wired or wireless transmission means to send physiologic information to alarm unit.
Lead-out unit 39 is used to receive physiologic information, video signal and/or the image that sends from memory element 38, and with physiologic information, video signal and/or image to export to external equipment such as printer, computer, display or mobile phone etc. such as forms such as txt, ASCII.
In the present embodiment; Can physiological signal detecting unit 31, physiological single processing unit 32, video signal processing unit 33, the second video signal matching unit 41, control unit 35, memory element 38 and lead-out unit 39 be arranged at the inside of same housing (not shown); Projecting cell 34 is arranged at the outside of this housing, and input block 40 is arranged on the outer surface of this housing to make things convenient for user's input operation instruction.In practical application; Can adopt dismountable mode to be connected between projecting cell 34 and the housing; This not only can make the user can regulate the projection angle of projecting cell 34 more neatly; But also can make things convenient for the user to carry projecting cell 34 separately, thereby it is applied on other physiological monitor that is arranged in diverse location or occasion.
Need to prove; In the present embodiment; The quantity of projecting cell 34 is one, but the present invention is not limited thereto, in practical application; The quantity of projecting cell 34 also can be for more than one, so as watch number more, watch the place big and need carry out making in the occasion such as comprehensive demonstration many people can be simultaneously and the testing result of clearly observing physiological monitor to image.When the quantity of projecting cell 34 is one when above, video signal processing unit 33 is sent to each projecting cell 34 respectively with video signal, throws demonstration simultaneously for each projecting cell 34.
Also need to prove; In the present embodiment; Projection angle regulon 36 is according to the projection angle of regulating projecting cell 34 from the projection angle control signal of projection angle control module 351; Projection tone regulon 37 is according to the projection tone of regulating projecting cell 34 from the projection tone control signal of projection tone control module 352, but the present invention is not limited thereto, in practical application; Physiological monitor can also adopt such as manual control and wait other control modes to regulate the projection angle and the projection tone of projecting cell 34; In fact, everyly the control mode that projection angle regulon 36 and projection tone regulon 37 are regulated the projection angle and the projection tone of projecting cell 34 can be controlled, protection scope of the present invention all should be regarded as.
In addition, in practical application, projection tone regulon 37 can also be regulated the projection tone of projecting cell 34 automatically according to the light situation around the projection screen.For example, can on projecting cell 34, be provided with, and in projection tone regulon 37, the light signal processing module is set such as light sensing devices such as light probes.During use, the light sensing device detects the light signal around the projection screen, and this light signal is sent to the light signal processing module; The light signal processing module is regulated the projection tone of projecting cell 34 automatically according to this light signal.
Further need to prove; Although control unit in the present embodiment 35 and input block 40 all are arranged on the inside of housing; But the present invention is not limited thereto, and in practical application, control unit 35 and/or input block 40 can also be arranged on the outside of housing.For example, when control unit 35 and input block 40 all were arranged at housing outside, input block 40 can be integrated in the equipment such as wired or wireless remote controller, panel computer, mobile phone with control unit 35 in the lump.For another example, when control unit 35 is arranged at the inside of housing, and input block 40 is when being arranged at housing outside, and input block 40 can be integrated in the equipment such as wired or wireless remote controller, panel computer, mobile phone.Control unit 35 and/or input block 40 are arranged on the outside of housing, the user can be operated in different positions, thereby carry out bringing convenience such as the therapeutic process of operation etc. to medical personnel.
Need to prove in addition; The physiological signal of gathering when physiological signal detecting unit 31 is during for more than one; It is only to demonstrate the preset pairing physiologic information of one or more physiological signals that the user can select projecting cell 34 through input block 40 and control unit 35, still demonstrates the pairing physiologic information of whole physiological signals.
Embodiment two
