Fig. 9 is the schematic diagram of the digital regulation resistance of the present patent application embodiment;It includes the resistance, N number of that N number of resistance is Rs Analog switch and a decoder composition.When the decoder supplied with digital signal as digital regulation resistance input when, institute One of conducting that decoder always controls N number of analog switch is stated, remaining analog switch is then closed.It is false If the input of the decoder is D, then decoder will control the D analog switch between Ax and Wx to open, then Ax Resistance value R and Wx between can be expressed as
R=Rs*D
It is achieved thereby that conversion work of the digital quantity of digital value realization to resistance value.Under normal circumstances, due to semiconductor The limitation of technique, it is smaller that the resistance of Rs cannot be done, otherwise accuracy, uniformity and stability it is difficult to ensure that.Such In the case of, optionally, in some embodiments, it is necessary to which analog processing circuit enters the resistance output end of multiple digital regulation resistances Go in parallel or in series, so as to the output area of resistance is identical with the resistance input range of multi-parameter monitor.
In the present embodiment, be converted into for the simulated vital sign data to digitize life entity by the front end acquisition module When levying data, it is sent in the data of rear end resistance output module by wireless communication channel and includes the patient ID, described The digital temperature data of front end acquisition module ID.
In the present embodiment, the rear end resistance output module is used to receive the digitlization by the wireless communication channel Vital sign data, and the digitlization vital sign data is converted to the analog electrical signal that can be received by patient monitor.Specifically Principle is that the principle and head temperature acquisition module of multi-parameter monitor measurement temperature value are identicals, and multi-parameter monitor leads to The resistance value of detection input signal is crossed, then according to resistance value and the relation of temperature value, is calculated correctly by look-up table Temperature value, so as to be shown on screen.Patient monitor in current industry has two kinds of standards, and one kind is 25 DEG C of 2.25K@, separately Outer one kind is 25 DEG C of 10K@.Therefore the rear end resistance output module only needs to carry out resistance according to the corresponding standard of patient monitor defeated Go out, multi-parameter monitor can be shown corresponding temperature value on screen.Assuming that human body temperature is 37 DEG C, head temperature Acquisition module measures human body temperature for 37 DEG C, so as to the temperature value is sent into rear end by temperature value by wireless communication channel Resistance output module, rear end resistance output module receives the digital quantity temperature value, will control inside digital regulation resistance and mould Intend process circuit and export a resistance value for 1.35K (according to 25 DEG C of standards of 2.25K@), the resistance is connected to multi-parameter monitoring After on instrument, multi-parameter monitor is then shown as 37 DEG C.
In the present embodiment, the back end signal recovery module will digitlization vital sign data be converted to can be by patient monitor During the analog electrical signal of reception, institute is parsed from the digitlization vital sign data that the front end acquisition module sends State the patient monitor that the patient ID and front end acquisition module ID is pointed to.
In the above-described embodiments, the simulated vital sign data is converted into digital by the front end acquisition module During life sign data, the uniqueness ID of different front end acquisition modules will be recognized and the digitlization vital sign data is loaded into In, the digitlization vital sign data for carrying the front end acquisition module uniqueness ID is sent by wireless communication channel.Enter One step ground, the back end signal recovery module will digitize vital sign data be converted to can by patient monitor receive simulation electricity During signal, the front-end collection mould is parsed from the digitlization vital sign data that the front end acquisition module sends The uniqueness ID of block, and the digitlization vital sign data that uniqueness ID is pointed to is changed.
In another embodiment, can also include on the basis of above-described embodiment:The front end acquisition module and rear end Signals revivification module is identified matching and setting up the wireless communication channel.Specifically, the front end acquisition module and rear end When signals revivification module is identified matching, the digitlization vital sign data that the back end signal recovery module identification is received Intensity, and the corresponding front end acquisition module of digitlization vital sign data with signal intensity more than setting intensity threshold Automatic identification matching is carried out, and sets up the wireless communication channel;Or, the front end acquisition module and back end signal also grand master pattern When block is identified matching, the predefined action synchronously carried out by both is matched come automatic identification.
Under normal circumstances, the matching of radio transmission apparatus is a critically important job, and the point can ensure multiple wireless Transmission equipment works simultaneously in the case that, the front end acquisition module and the back end signal recovery module also can be to accomplish one One correspondence, data transfer not crosstalk from each other, the different back end signal recovery modules each receive each self-corresponding The data that the front end acquisition module sends out.Typically in the case where display device is possessed, shown according to display device The uniqueness ID of different front end acquisition modules judges.But the Auto-matching to the equipment without display is difficult to realize.
