The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the wrist formula measurement of muscule strength dynamometry device of this utility model sends to host computer muscular strength apparatus for evaluating through Bluetooth protocol with test data.Comprise portable housing 1, measurement of muscule strength dynamometry pick off 2, power supply 3, power management module 4, signal condition module 5, microprocessor 6 and bluetooth sending module 7.Measurement of muscule strength dynamometry pick off 2 is inlaid in the bottom surface of housing 1, and power supply 3, power management module 4, signal condition module 5, microprocessor 6 and bluetooth sending module 7 are arranged in the housing.Power management module 4 links to each other with power supply 3 and converts supply voltage into each and outputs to each with electric device (signal condition module 5, microprocessor 6 and bluetooth sending module 7) with the required electric pressure of electric device; The outfan of measurement of muscule strength dynamometry pick off 2 connects the input of signal condition module 5; The outfan of signal condition module 5 connects the input of microprocessor 6, and the outfan of microprocessor 6 connects the input of bluetooth sending module 7.Power supply 3 wherein adopts No. 7 alkaline batteries of 4 joint 1.5V, provide+the 6V supply voltage, again through two integrated package of pressure-stabilizing produce respectively+5V ,+the 3.3V supply voltage.The bluetooth sending module adopts the BC4EXTA of CSR company.The range of measurement of muscule strength dynamometry pick off is 0~50Kg.
This utility model also is provided with the button 8 that is used to control the output of bluetooth sending module signal; This button 8 is installed in an end of housing 1; When the pressure that puts on the measurement of muscule strength dynamometry pick off as the patient reaches maximum, push button, the bluetooth sending module is to host computer output muscular strength signal.
This utility model also is provided with bluetooth connection status display lamp 9, power supply indicator 10 and on and off switch 11.Bluetooth connection status display lamp 9, power supply indicator 10 and on and off switch 11 are installed in the other end of housing 1 side by side, when bluetooth sending module 7 powers on but is not connected with host computer, 9 flickers of bluetooth connection status display lamp; When bluetooth sending module and host computer successful connection, bluetooth connection status display lamp Chang Liang.
