Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to an ultrasonic probe that irradiates a human body with ultrasonic waves and receives reflected waves to detect tissue in the human body.
[0002]
[Prior art]
As this type of ultrasonic probe, as shown in FIG. 3, a plurality of ultrasonic transducers (not shown) are mounted in the probe main body 1, and the ultrasonic irradiation unit 1 a is connected to the probe main body 1 with a water bag 2. Is attached, and a grip portion 3 is attached to an opposite portion of the water back 2 of the probe body 1.
[0003]
[Problems to be solved by the invention]
However, in such an ultrasonic probe, when the water bag 2 is brought into contact with the human body 4 while holding the grip portion 3, the contact surface of the water bag 2 with the human body 4 is soft, so that the grip portion 3 with respect to the human body 4 is soft. It is difficult to vertically support the ultrasonic wave from the ultrasonic transducer mounted in the probe main body 1, and it is difficult to detect a tissue of a necessary part of the human body. There was a problem that there was.
[0004]
[Means to solve the problem]
According to the present invention, a resinous water bag filled with water as a propagation medium is brought into contact with a human body, the water bag is mounted on an ultrasonic irradiation unit of a probe main body, and a plurality of ultrasonic transducers mounted on the probe main body are used. ultrasound through the water back irradiating the human body, in the ultrasonic probe in which the reflected wave of the ultrasonic wave to detect the tissue in the human body and received respectively by the ultrasonic transducers in the probe body the probe reflector inclined at approximately 45 degrees to the opposite surface of the ultrasonic irradiation of the body is attached to the water back, the probe main body of the approximately 90 ultrasound in the water back from the ultrasonic vibrator and degree change, and receives from the radiation and the human body to the human body from the side parallel to the side surface of the water bag of the probe body.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, by installing a reflector inclined at about 45 degrees in the water bag, the ultrasonic wave is irradiated perpendicularly to the human body from the ultrasonic irradiation surface of the water bag simply by bringing the probe body into contact with the human body. The tissue in the human body that is in contact with the irradiation surface of the water back can be reliably detected.
[0006]
【Example】
1 is a plan view of an ultrasonic probe according to an embodiment of the present invention, FIG. 2 is a partial cross-sectional side view of the ultrasonic probe of FIG. 1, an ultrasonic probe includes 1 a probe body, 2 a water back, 3 Is a gripping part, 4 is a human body, and since the configuration thereof is the same as the above-described conventional example, the description thereof will be omitted. The reflecting plate 5 is mounted in the water bag 2.
[0007]
In the ultrasonic probe of the present embodiment configured as described above, as shown in FIG. 2, when the side surface of the probe main body 1 is brought into contact with the human body 4, the ultrasonic irradiation surface 2 a of the water back 2 comes into contact with the human body 4. In this state, when an ultrasonic wave is emitted from the ultrasonic transducer built in the probe main body 1, the emitted ultrasonic wave is substantially perpendicular to the reflector 5 in the water back 2 mounted on the opposite surface of the ultrasonic transducer. It is bent and irradiated vertically into the human body 4 from the irradiation surface 2a of the water bag 2.
[0008]
Therefore, in the ultrasonic probe of the present embodiment, it is not necessary to hold the grasping portion 3 and support the ultrasonic probe so that the grasping portion is vertical as in the conventional ultrasonic probe, and the side surface of the probe main body 1 is attached to the human body. Since the ultrasonic wave is irradiated perpendicularly to the human body 4 from the irradiation surface 2a of the water back 2 simply by bringing it into contact with the body, the support angle of the grip portion 3 does not require accuracy, and the operation becomes simple and the handling becomes easy. .
[0009]
In addition, if the inclined plate 4 incorporated in the water bag 2 is set to 45 degrees or more, it can be used when inspecting the back of a human body that cannot move the body.
[0010]
【The invention's effect】
As described above, in the ultrasonic probe of the present invention, ultrasonic inspection is performed by attaching a reflector inclined at about 45 degrees to the opposite surface of the ultrasonic transducer in the water bag attached to the probe body. When the side of the probe body is in contact with the human body, the ultrasonic irradiation is perpendicular to the human body, so there is no need to support the grip portion of the probe body perpendicular to the human body, the operation is simple, There is an advantage that it is easy to handle.
