Master-slave Bluetooth transmission device for handheld instruments

Abstract

This invention provides a master-slave Bluetooth transmission device for a handheld instrument, comprising a processing unit, a master Bluetooth unit, and a slave Bluetooth unit. The master Bluetooth unit receives recording signals from a Bluetooth transmitter, enabling the processing unit to receive measurement signals from the handheld instrument. The slave Bluetooth unit then converts these measurement signals into an input command via a Bluetooth receiver and inputs it into the electronic device. Transmitting the handheld instrument's measurement signals to the electronic device via Bluetooth not only improves the overall quality of measurement recordings from the handheld instrument, freeing operators from the difficulty of multitasking, but also improves the accuracy of manual recordings and reduces the risk of high-risk human error.

Claims

1. A master-slave Bluetooth transmission device for a handheld instrument, comprising: A processing unit is provided for connection to a handheld instrument device to receive measurement signals from the handheld instrument. A primary Bluetooth unit is connected to the processing unit and is connected to a Bluetooth transmitter to receive a recording signal transmitted by the Bluetooth transmitter; a secondary Bluetooth unit is connected to the processing unit and is connected to a Bluetooth receiver; wherein, when the processing unit receives the recording signal through the primary Bluetooth unit, the processing unit reads the measurement signal of the handheld instrument and generates a data signal accordingly, and transmits the data signal to the Bluetooth receiver through the secondary Bluetooth unit.

2. The master-slave Bluetooth transmission device for a handheld instrument as described in claim 1 further comprises: a battery unit; and a power conversion unit electrically connected to the battery unit, the processing unit, the master Bluetooth unit, and the slave Bluetooth unit to receive battery power from the battery unit, convert the battery power to generate power, and supply the power to the processing unit, the master Bluetooth unit, and the slave Bluetooth unit.

3. The master-slave Bluetooth transmission device for the handheld instrument as described in claim 2, wherein, This power conversion unit is a step-down converter.

4. The master-slave Bluetooth transmission device for the handheld instrument as described in claim 1, wherein, The handheld instrument device is for connecting to a handheld instrument probe, and the handheld instrument probe is equipped with the Bluetooth transmitter.

5. The master-slave Bluetooth transmission device for the handheld instrument as described in claim 1, wherein, The data signal generated from the Bluetooth unit is a Bluetooth keyboard input signal.

6. The master-slave Bluetooth transmission device for the handheld instrument as described in claim 1, further comprising: an integrated bus circuit; wherein, The processing unit is connected to the master Bluetooth unit and the slave Bluetooth unit through the integrated bus circuit.

7. The master-slave Bluetooth transmission device for the handheld instrument as described in claim 1, further comprising: a transmission device interface connected to the processing unit; wherein, The processing unit is connected to the handheld instrument device through the transmission device interface; wherein, the transmission device interface is a universal serial bus interface.
