Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ultrasonic diagnostic device used as a medical diagnostic device.

Conventional configuration and its problems Conventional ultrasound probes with a built-in transmitter/receiver circuit are directly connected to the ultrasound diagnostic equipment main body via a cable. Transmission signals to the ultrasound probe and reception signals from the ultrasound probe to the main body of the ultrasound diagnostic apparatus are processed by a transmission/reception circuit built into the ultrasound probe.

However, in recent years, ultrasonic probes that do not have a built-in transmitter/receiver circuit have become popular in order to reduce weight and size. When using the ultrasound diagnostic apparatus main body using this ultrasound probe, it is naturally impossible to use it because there is no transmitting/receiving circuit.

Therefore, by providing an ultrasonic diagnostic device adapter dedicated to the transmitter/receiver circuit, it becomes possible to use an ultrasound probe that does not have a built-in transmitter/receiver circuit.

However, since the above ultrasound diagnostic device adapter does not have a frequency type function, for example, for an ultrasound probe with a drive frequency of 3 MHz, only the ultrasound diagnostic device adapter dedicated to the above ultrasound probe can be used. , ultrasound probes with drive frequencies of different frequencies, such as 5 MHz, required separate ultrasound diagnostic device adapters.

As a result, in order to use an ultrasound probe with a different drive frequency, the ultrasound diagnostic device adapter must be replaced, making handling inconvenient and cumbersome for those performing diagnosis. .

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide an ultrasonic diagnostic device that can be used with ultrasonic probes of different drive frequencies using a single ultrasonic diagnostic device adapter.

Structure of the Invention The present invention provides a first probe drive frequency that corresponds to a first ultrasonic probe sent out from the main body side, and a second probe drive frequency that corresponds to a second ultrasonic probe. The above object is achieved by providing a frequency changing means for changing the frequency of the child drive frequency.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

The figure shows a block configuration of an ultrasonic diagnostic apparatus according to an embodiment of the present invention.

In the figure, reference numeral 1 denotes an ultrasonic diagnostic apparatus main body, which inputs information signals necessary for ultrasonic diagnosis to a transmitter 2 in an ultrasonic diagnostic apparatus adapter 10. Note that the ultrasonic diagnostic apparatus adapter 10 is provided between the cable connecting the apparatus main body 1 and the ultrasonic probe 8. The transmitter 2 sends the input information to the transmit pulse generator 3, which generates a plurality of transmit pulses of different frequencies. These frequencies are then sent to the pulse switching circuit 4.

Reference numeral 5 denotes a frequency classification circuit 6, which generates a signal indicating the type using the ultrasonic probe 8. A switching control circuit 6 generates a control signal for the pulse switching circuit 4 based on the probe type signal inputted from the frequency type circuit 5.

The transmission pulse switching circuit 4 selects a transmission pulse using the signal obtained from the transmission pulse generator 3 and the switching control circuit 6,
The selected one is amplified by the amplifying section 7 and sent to the ultrasonic probe 8. In the ultrasonic probe, the signal is applied to the transducer, and the receiving section 9 receives the reflected signal. Then, it is displayed by the ultrasound diagnostic apparatus main body 1.

As described above, according to this embodiment, the ultrasonic probe 8 generates a signal in the frequency type circuit 6 indicating the type, and sends it to the switching control circuit 6 to instruct it, thereby operating the transmission pulse switching circuit 4. can be done.

That is, even if the ultrasonic probe 8 has a different frequency, transmission pulses can be matched.

As a result, there is no need to replace the ultrasonic diagnostic device adapter 10 each time, which eliminates the burden on the diagnostician.

In this embodiment, the driving frequency corresponding to the ultrasonic probe 8 is configured so that the frequency type circuit 5 can be manually instructed. It will be even more convenient if the frequency type circuit 5 is driven by the signal.

Further, in this embodiment, the ultrasound diagnostic device adapter 10 is provided between the cable connecting the ultrasound diagnostic device main body 1 and the ultrasound probe 8, but the ultrasound diagnostic device adapter 10 is provided on the ultrasound diagnostic device main body 1 side. may be provided.

Effects of the Invention As described above, the present invention provides a frequency changing means for adjusting the frequency according to the ultrasonic probe, thereby improving the efficiency of diagnosis.
There is no need to replace the ultrasonic diagnostic device adapter, which eliminates the burden on the diagnostician, which has a great effect.
