DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasound
probe for an ultrasound diagnostic device. An ultrasonic probe (hereinafter simply referred to as
a probe) of an ultrasonic diagnostic apparatus needs to be cleaned and disinfected in order to
directly touch the patient's body for its use, and waterproofness and sealing are required. FIG. 1
is a view showing the appearance of a general probe. In FIG. 1, a rubber cover 1 is provided with
a functional element such as an ultrasonic transducer inside. 2 is a case of a probe, which is
generally made of plastic (1) which resin. A cable 5 is composed of a cable for transmitting an
input / output signal of the functional element described above to the main body (not shown) of
the ultrasonic diagnostic apparatus. Although the rubber cover 1 and the case 2 have a structure
such that there is no obstruction to the sealing property, the conventional problem is how to
airtightly bond the joint portion between the rubber cover 1 and the case 2 The A conventional
example showing this bonding is shown in FIG. FIG. 2 is a view mainly showing a cross section of
a bonding portion when it is cut along an A plane in FIG. As shown in FIG. 2, a 7-character insert
is a rubber cover as described above, and 1all + on the front face also functions as an acoustic
lens. 2 is a case of a probe and 4 is a functional element configured by an ultrasonic transducer
or the like. The probe shown in FIG. 2 constitutes a sealed case by bonding the rubber cover 1
and the case 2 at a portion indicated by 5, but this bonding is conventionally performed by
bonding with an adhesive. However, the rubber cover 1 made of rubber is poor in adhesion as it
is made of material, and it only requires a lot of working time required for adhesion, but in the

case where external force is applied to the contact layer portion (2) There was an undesirable
side. In the present invention, the convex portion is provided on a part of the rubber cover, and
the convex portion of the rubber cover is mechanically pressed (pressure-welded) in the case
portion of the probe to achieve sealing property, and more than the conventional adhesion. It is
intended to make strong bonding easier. FIG. 3 is a cross-sectional view of a probe according to
an embodiment of the present invention. That is, FIG. 5 is a view showing a bonded state of the
rubber cover and the case of the probe in the case of being cut at surface A of FIG. In FIG. 5, 1 is
a rubber cover, and as in FIG. 2, the ld section on the front side also functions as an acoustic lens.
Further, the rubber cover 1 is provided with a convex portion indicated by lb and a concave
portion indicated by IC around the opening indicated by ld. A probe case 2 is made of a resin
such as plastic and has a rectangular opening 2b for providing the rubber cover 1 and the
functional element at one end, and the other end is an opening for inserting a pressing block or
the like described later However, after the pressing block and the like are provided in the case 2,
the opening at the other end is sealed (3) by a cover (not shown).
A projection 2a is provided on the inner side of the edge of the rectangular opening 2b of the
case 2 as shown in FIG. Reference numeral 4 is a functional element composed of an ultrasonic
transducer or the like, and 6 is the above-mentioned pressing block. As shown in FIG. 5, the
protrusion 2a of the case 2 and the pressing block 6 The presser sealability is obtained. FIG. 4 is
a view showing the appearance of the rubber cover 1. As shown in FIG. 4, the rubber cover 1 has
a case-like shape so as to cover the functional element 4 and has a convex portion 1b around the
opening 1d. As described above, according to the present invention, it is simple to simply provide
a convex portion on the rubber cover and mechanically press-contact using the convex portion
without performing adhesion of rubber which requires much time as in the prior art. By such an
operation, a probe having a good sealability can be obtained, and even if an external force is
applied to the joint portion, the effect is obtained such that the sealability is superior to that by
the conventional adhesion, etc. (4) FIG. 1 is a view showing the appearance of a general probe,
FIG. 2 is a cross-sectional view showing a conventional probe, and FIG. FIG. 4 is a cross-sectional
view showing an embodiment, and FIG. 4 is a view showing an appearance of a rubber cover. 1rubber cover, la · · · acoustic lens, 1 b · · convex portion, IC · concave portion 1 d · opening portion
