초음파 진단장치는 초음파 프루브(probe)를 통해 피검사체에 초음파를 방사하고 반사되는 초음파를 수신함으로써 얻어지는 에코데이터를 처리하여 피검사체 내의 단층화상 또는 혈류화상 등을 나타내는 장치이다. 초음파 프루브(이하, 프루브라고 칭함)는 초음파 신호와 전기신호를 상호변환하는 트랜스듀서를 포함한다. 트랜스듀서는 다수의 초음파 진동자(Ultrasonic Element)들의 집합체를 구비하며, 피검사체에 초음파를 방사한 후, 그 반사된 초음파 신호를 전기신호로 변환하여, 초음파 진단장치의 이미지 처리장치로 전송한다. 이미지 처리장치는 전송받은 신호를 통해 영상을 생성한다. 이러한 초음파 진단장치는 생명체 내의 이물질의 검출, 상해(lesion) 정도의 측정, 종양의 관찰 및 태아의 관찰 등과 같이 의학용으로 유용하게 사용된다. The ultrasonic diagnostic apparatus is an apparatus for displaying tomographic images or blood flow images in a subject by processing echo data obtained by radiating ultrasonic waves to a subject through ultrasonic probes and receiving reflected ultrasonic waves. Ultrasonic probes (hereinafter referred to as probes) include transducers for converting ultrasonic signals from electrical signals. The transducer includes a plurality of ultrasonic elements, and the ultrasonic waves are radiated to the subject, and then the reflected ultrasonic signals are converted into electrical signals and transmitted to the image processing apparatus of the ultrasonic diagnostic apparatus. The image processing apparatus generates an image through the received signal. Such ultrasonic diagnostic apparatuses are useful for medical purposes, such as detection of foreign substances in living organisms, measurement of degree of injury, observation of tumors, and observation of fetuses.

도 1은 종래기술에 따른 초음파 진단장치의 프루브의 내부를 도시한 단면도이다. 도 1에 도시된 바와 같이, 프루브(1) 내부에는 트랜스듀서(30)의 회동을 원활하게 하고 초음파 진행의 매질이 되는 오일(2)이 커버(12) 내부에 채워진다. 오일(2)의 누유를 방지하기 위하여, 트랜스듀서(30) 하부는 고무막(40)으로 감싸지며, 고무막(40)의 가장자리는 커버(12)의 가장자리에 고정되고, 하부는 클램프(50)에 의해 압착된다. 커버(12)의 가장자리는 커버(12)와 고무막(40) 내에 오일을 밀봉하기 위한 실부재인 고정링(13)이 삽입되도록 고정홈(14)이 형성되며, 고정홈(14)에 고무막(40)의 가장자리가 삽입되고, 고정링(13)이 고무막(40)을 가압하며 삽입된다. 고정링(13)은 플라스틱과 같은 합성수지로 이루어지며, 고정홈(14)에 대응하는 형상으로 제조된 것이다. 트랜스듀서(30)와 연결된 케이블(31)이 연장되 는 고무막(14)의 하부는 클립, 집게 등과 같은 클램프수단(50)으로 클램프된다.1 is a cross-sectional view showing the inside of the probe of the ultrasonic diagnostic apparatus according to the prior art. As shown in FIG. 1, inside the probe 1, oil 2, which smoothly rotates the transducer 30 and serves as a medium for ultrasonic propagation, is filled in the cover 12. In order to prevent the oil 2 from leaking, the lower portion of the transducer 30 is wrapped with the rubber membrane 40, the edge of the rubber membrane 40 is fixed to the edge of the cover 12, and the lower portion is clamp 50. It is compressed by). The edge of the cover 12 has a fixing groove 14 is formed so that the fixing ring 13 which is a seal member for sealing the oil in the cover 12 and the rubber film 40 is formed, the rubber in the fixing groove 14 The edge of the membrane 40 is inserted, and the fixing ring 13 is inserted while pressing the rubber membrane 40. The fixing ring 13 is made of a synthetic resin such as plastic, and is manufactured in a shape corresponding to the fixing groove 14. The lower portion of the rubber film 14, from which the cable 31 connected to the transducer 30 extends, is clamped by clamp means 50 such as clips, tongs, and the like.

그러나 고무막(40)을 고정홈(14)에 걸친 후 고정링(13)으로 압입하는 과정에서 고정링(13) 압입에 큰 힘이 필요하기 때문에 고정링 압입과정에 힘이 많이 들어 제조 작업이 어렵고 조립시간이 오래 걸리는 문제점이 있다.However, since a large force is required to press the fixing ring 13 in the process of pressing the rubber membrane 40 through the fixing groove 14 and then pressing it into the fixing ring 13, the manufacturing work is difficult due to a large amount of force in the fixing ring pressing process. It is difficult and takes a long time to assemble.

또한, 고무막(40)을 고정링(13)을 이용하여 고정홈(14)에 압입하는 밀봉과정에서 고무막이 찢어질 수 있는 또 다른 문제점이 있다.In addition, there is another problem that the rubber film may be torn in the sealing process in which the rubber film 40 is pressed into the fixing groove 14 by using the fixing ring 13.

본 발명은 상기와 같은 제반 문제점을 해결하기 위한 것으로서, 초음파 진단장치 프루브의 커버 내부에 충전된 오일이 누유되지 않도록 고무막으로 프루브의 커버를 밀봉하여 오일의 누유를 방지하는 밀봉 작업을 신속하게 수행할 수 있고 밀봉 작업에 과도한 힘이 들지 않는 프루브를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, the sealing operation to prevent the oil leakage by sealing the cover of the probe with a rubber film so as not to leak the oil filled inside the cover of the ultrasonic diagnostic apparatus probe quickly performed The purpose is to provide a probe which can be made and does not take excessive force in the sealing operation.

본 발명의 초음파 진단장치의 프루브의 바람직한 실시예에 따르면, 피검사체와 접촉하는 커버와, 상기 커버 내측 둘레에 가장자리가 밀착하는 고무막과, 일정 장력으로 상기 고무막을 커버측으로 가압하는 와이어와, 그리고 상기 커버와 고무막 사이에 배치되는 트랜스듀서를 포함하고, 상기 커버와 고무막 사이에 오일이 충전된다.According to a preferred embodiment of the probe of the ultrasonic diagnostic apparatus of the present invention, a cover in contact with the inspected object, a rubber film whose edge is in close contact with the inner circumference of the cover, a wire for pressing the rubber film to the cover side with a constant tension, and And a transducer disposed between the cover and the rubber membrane, wherein oil is filled between the cover and the rubber membrane.

상기 고무막의 중앙부는 관통되고, 상기 고무막 중앙부로 일측이 트랜스듀서와 연결되고 타측이 외부로 연장되는 케이블이 통과하며, 상기 고무막과 케이블은 클램프되어 밀봉될 수 있다.A central portion of the rubber membrane penetrates, and a cable through which one side is connected to the transducer and the other side extends to the rubber membrane center portion passes through the rubber membrane, and the rubber membrane and the cable may be clamped and sealed.

상기 커버 내측 둘레에는 고정홈이 형성되고, 상기 고무막의 가장자리가 상 기 고정홈의 내측에 삽입되며, 상기 와이어는 상기 고무막 가장자리를 가압하며 고무막 가장자리와 함께 상기 고정홈에 삽입되는 것이 바람직하다.A fixing groove is formed in the inner circumference of the cover, and an edge of the rubber membrane is inserted into the fixing groove, and the wire presses the rubber membrane edge and is inserted into the fixing groove together with the rubber membrane edge. .

이하, 도 2 및 도 3을 참조하여 본 발명에 따른 프루브의 일 실시예를 설명한다.Hereinafter, an embodiment of a probe according to the present invention will be described with reference to FIGS. 2 and 3.

도 2는 본 발명에 따른 초음파 진단장치의 프루브의 누유방지부의 단면을 도시한 사시도이고, 도 3은 본 발명에 따른 초음파 진단장치의 프루브의 누유방지부의 조립 과정을 도시한 사시도이다. 도 2 및 도 3에 도시된 바와 같이, 프루브의 커버(112) 내부에는 초음파 진동자 집합체(131)가 구비된 트랜스듀서(130)가 장착된다. 트랜스듀서(130)는 프루브의 내부에서 왕복 운동하며 초음파 진동자 집합체(131)에서 피검사체에 방사된 초음파의 에코 데이터를 읽어들인다. 이러한 에코데이터는 케이블(132)을 통해 초음파 진단장치에 전송된다. 초음파 진단장치의 이미지 처리부(도시되지 않음)에서는 트랜스듀서(130)에서 전송된 에코 데이터를 이용하여 3차원의 이미지를 생성한다. 커버(112) 둘레에는 고정홈(114)이 형성되고, 그 내부에 고무막(140)의 가장자리(141)가 고정홈(114)에 삽입된다. 와이어(150)가 고정홈(114)에 삽입된 고무막(140)의 가장자리(141)를 누르면서 고정홈(114)에 삽입된다. 와이어의 양 단은 조여지거나 매듭처리된다.Figure 2 is a perspective view showing a cross section of the leak prevention portion of the probe of the ultrasonic diagnostic apparatus according to the present invention, Figure 3 is a perspective view showing the assembly process of the leak prevention portion of the probe of the ultrasonic diagnostic apparatus according to the present invention. As illustrated in FIGS. 2 and 3, the transducer 130 having the ultrasonic vibrator assembly 131 is mounted inside the cover 112 of the probe. The transducer 130 reciprocates inside the probe and reads echo data of ultrasonic waves emitted from the ultrasonic vibrator assembly 131 to the object under test. Such echo data is transmitted to the ultrasound diagnosis apparatus via the cable 132. An image processor (not shown) of the ultrasound diagnosis apparatus generates a 3D image by using echo data transmitted from the transducer 130. A fixing groove 114 is formed around the cover 112, and the edge 141 of the rubber film 140 is inserted into the fixing groove 114 therein. The wire 150 is inserted into the fixing groove 114 while pressing the edge 141 of the rubber film 140 inserted into the fixing groove 114. Both ends of the wire are tightened or knotted.

고무막(140)의 중앙부는 커버(112)와 고무막(140) 사이에 배치된 트랜서듀서(130)로부터 케이블(132)이 외부로 연장될 수 있도록 관통되어 있다. 케이블(132)은 일측단이 트랜스듀서(130)와 연결되고 타측단은 외부로 연장되는데, 도 시하지는 않았지만, 타측단은 고무막(140)과 함께 클램핑된다. 따라서, 고무막(140)과 커버(112) 사이에 충전된 오일이 누유되지 않는다.The central portion of the rubber membrane 140 penetrates from the transducer 130 disposed between the cover 112 and the rubber membrane 140 so that the cable 132 can extend to the outside. One end of the cable 132 is connected to the transducer 130 and the other end extends to the outside, although not shown, the other end is clamped together with the rubber membrane 140. Therefore, the oil filled between the rubber film 140 and the cover 112 is not leaked.

이하, 상기와 같이, 구성된 프루브의 누유방지장치의 조립과 작용효과를 설명한다.Hereinafter, assembling and action effects of the leak prevention apparatus of the configured probe will be described.

프루브 커버(112)의 가장자리에는 고정홈(114)이 형성되어 있으며, 고무막의 가장자리(141)가 와이어(150)에 의해 고정홈(114)에 삽입된다. 와이어의 양단을 조이거나 매듭을 형성하면서 와이어의 장력을 조절할 수 있어서, 밀봉작업이 편리하다. 즉, 종래기술에서는 고정링은 정해진 형상으로 성형되므로 고무막(112) 전체가 균일하게 가압되는지 확인할 수 없고, 고정링을 고정홈에 탄성 압입하는 과정에서 작업자가 과도한 힘을 들여야 하지만, 본 발명에서는 고정홈(114)에 삽입된 와이어(150)의 양단을 조여 와이어에 장력을 인가할 수 있어서, 고무막(140)을 균일하게 커버(112) 측으로 가압할 수 있다. 따라서, 밀봉의 불량이 거의 발생하지 않으며, 작업자가 큰 힘을 들이지 않고 밀봉작업을 수행할 수 있다.The fixing groove 114 is formed at the edge of the probe cover 112, and the edge 141 of the rubber film is inserted into the fixing groove 114 by the wire 150. The tension of the wire can be adjusted by tightening both ends of the wire or forming a knot, so that the sealing operation is convenient. That is, in the prior art, the fixing ring is molded into a predetermined shape, so that the entire rubber film 112 cannot be uniformly pressed, and the operator must exert excessive force in the process of elastically injecting the fixing ring into the fixing groove. Tension may be applied to the wire by tightening both ends of the wire 150 inserted into the fixing groove 114, so that the rubber membrane 140 may be uniformly pressed toward the cover 112. Therefore, the sealing failure hardly occurs, and the worker can perform the sealing operation without applying great force.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의하여 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경할 수 있다는 것이 본 발명이 속하는 분야에서 통상의 지식을 가진 자에게 있어서 명백할 것이다.The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it is common in the field of the present invention that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have knowledge.

전술한 바와 같이 본 발명에 따르면, 프루브 내부에 충전된 오일이 외부로 누출되지 않도록 프로브의 커버에 고무막을 밀착시키는 밀봉 과정을 작업자가 큰 힘을 들이지 않고 신속하게 수행할 수 있으며, 고무막의 일부를 과도하게 가압하지 않기 때문에 고무막이 찢어져 불량이 발생할 확률이 낮은 효과가 있다.As described above, according to the present invention, the sealing process of bringing the rubber film into close contact with the cover of the probe so as not to leak the oil filled inside the probe to the outside can be performed quickly by the operator without a large force, and a part of the rubber film Since the pressure is not excessively pressurized, the rubber film is torn and there is a low probability of failure.

또한, 본 발명에 따르면, 와이어의 장력으로 고무막을 프루브의 커버에 가압하여 밀봉하므로, 고무막이 균일하게 가압될 수 있어서 오일 누유의 확률이 낮은 또 다른 효과가 있다.In addition, according to the present invention, since the rubber membrane is pressed against the cover of the probe by the tension of the wire, the rubber membrane can be uniformly pressurized, and thus there is another effect of low probability of oil leakage.
