Description

전립선 치료용 카테터{Catheter for prostate remedy}Catheters for the treatment of prostate {Catheter for prostate remedy}

본 발명은 카테터에 관한 것으로, 더욱 상세하게는 요도에 삽입되어 전립선에 약물을 주입할 때 자중에 의해 빠지지 않도록 하는 전립선 치료용 카테터에 관한 것이다.The present invention relates to a catheter, and more particularly, to a catheter for prostate treatment that is inserted into the urethra and prevented from falling by its own weight when injecting drugs into the prostate.

전립선 치료용 카테터는 요도에 삽입되어 전립선에 약물을 주입하는 기기이다.A prostate catheter is a device that is inserted into the urethra to inject drugs into the prostate gland.

전립선은 무게는 약 20g이며, 밤톨 모양이다. 방광 바로 밑에 위치하며, 전립선 가운데에 나 있는 구멍으로 사정관과 요도가 통과한다.The prostate weighs about 20g and is shaped like chestnut. Located directly beneath the bladder, it is a hole in the middle of the prostate that passes through the ejaculatory tube and urethra.

정액은 정자를 포함하고 있으며, 저정낭을 지나면서 저정낭에서 분비된 액체가 정액에 더해지게 된다. 정액은 사정관을 지나 요도로 들어가게 되는데 그 경계 부위에 전립선이 있다. 전립선은 정액의 액체 성분의 30% 이상을 만들어서 분비한다.The sperm contains sperm, and the liquid secreted from the vesicles is added to the sperm as it passes through the sperm capsule. Semen enters the urethra after passing through the ejaculation canal, with the prostate at its border. The prostate glands make up and secrete more than 30% of the semen's liquid components.

전립선에서 만들어진 전립선액은 정소에서 만들어져서 이동해 온 정자에게 영양을 공급하며, 사정된 정액이 굳지 않도록 액체로 유지시킴으로써 정자가 활발하게 운동할 수 있도록 돕는다. 이러한 정자의 운동 능력은 난자와 만나 수정할 수 있는 능력과 직접적으로 연결된다. 또한 여성의 질 속은 산성을 띠는데, 전립선액은 알칼리성이므로 산성을 중화시켜 정자를 보호하는 역할을 한다. 정액에서 나는 독특한 냄새는 전립선액에서 나는 것이다. Prostate fluid produced in the prostate gland nourish the sperm that has been made and transported in the testes, and helps the sperm to exercise vigorously by keeping the fluid in the liquid so that the ejaculated semen does not harden. The sperm's motor ability is directly linked to the ability to meet and fertilize an egg. In addition, the woman's vagina is acidic, the prostate fluid is alkaline, so neutralizes the acid serves to protect sperm. The peculiar smell of semen comes from the prostate fluid.

오줌이 배출되는 통로인 요도가 전립선의 가운데를 통과하기 때문에, 전립선이 커지게 되면 요도가 좁아져서 오줌이 통과하기 힘들게 된다. 이러한 전립선 비대증은 중년 남성에게 흔히 나타나는 질환이다. 또한 같은 증상으로 드물게 전립선암이 발견되기도 한다. 전립선암의 원인은 아직 명확하게 밝혀지지 않았으나 연령과 남성호르몬이 유발인자로서 관련이 있는 것으로 여겨지고 있다. 이외에소 전립선염 등 전립선에 관련된 질환은 다양하다.Because the urethra, the passage through which urine passes, passes through the center of the prostate gland, when the prostate enlarges, the urethra becomes narrower, making urine difficult to pass. This prostatic hyperplasia is a common disease in middle-aged men. In addition, prostate cancer is rarely found with the same symptoms. The cause of prostate cancer has not been elucidated yet, but age and male hormone are thought to be related as triggers. In addition, there are various diseases related to the prostate, such as bovine prostatitis.

전립선 질환의 치료에 있어서, 약물치료와 외과적 치료등이 병행되고 있는데, 약물치료는 치료의 효과가 높으면서도 부작용이 적고 치료비용도 저렴하여 많이 이용되고 있다.In the treatment of prostate disease, drug treatment and surgical treatment are performed in parallel, and drug treatment has been widely used because of its high effectiveness and low side effects and low cost of treatment.

약물치료에 있어서, 전립선에 약물을 직접 주입하는 것이 가장 효과적인데, 주사기 등을 통해 인체를 관통하여 주사하면 인체는 외과적 손상을 받을 수 받게 없으므로, 얇은 튜브를 요도를 통해 전립선까지 위치시킨 후 튜브를 통해 전립선에 직접 약물을 주입하는 방법이 가장 많이 이용되고 있다.In drug therapy, it is most effective to inject the drug directly into the prostate gland. If the injection is made through a human body through a syringe or the like, the human body cannot receive surgical damage. Therefore, a thin tube is placed through the urethra to the prostate tube. Injecting drugs directly into the prostate through the most widely used method.

전립선에 약물을 주입하는 시간은 질환의 종류나 환자의 상태에 다르겠지만, 일반적으로 수십분 내지 수시간씩 소요된다.The time to inject the drug into the prostate will vary depending on the type of disease or the condition of the patient, but generally takes tens of minutes to several hours.

이와 같이, 요도에 튜브를 삽입하고 상당한 시간을 들여 약물을 주입하면 주입하는 동안 튜브가 요도에서 빠지는 경우가 자주 발생된다. 따라서 약물 주입이 제대로 안되는 경우가 발생하게 된다.As such, when a tube is inserted into the urethra and the drug is injected for a considerable time, the tube often falls out of the urethra during the injection. Therefore, the drug is not properly injected.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 카테터를 구성하는 튜브를 요도에 삽입하여 전립선에 약물을 주입하는 동안 튜브가 요도에서 빠져나기자 않게 하고자 한다. 또한 전립선에 주입된 약물이 전립선에 흡수가 잘 될 수 있도록 전립선에 일정한 전압의 전류를 지속적으로 인가시킬 수 있도록 하고자 한다.The present invention is to solve the problems described above, to insert the tube constituting the catheter into the urethra so that the tube does not escape from the urethra while injecting drugs into the prostate. In addition, the drug injected into the prostate is to be able to continuously apply a current of a constant voltage to the prostate so that the prostate can be absorbed well.

본 발명은 전술한 바와 같은 목적을 달성하기 위하여 요도에 삽입되어 전립선에 약물을 주입하는 전립선 치료용 카테터에 있어서, 내튜브외 외튜브로 이루어지고 끝 부분에는 통공이 다수 형성된 튜브, 상기 튜브의 선단에서 분기되고 약물이 주입되는 제1메니홀드, 상기 튜브의 선단에서 분기되고 공기가 주입되는 제2메니홀드, 상기 튜브 내부의 선단에서부터 하단까지 삽입되어 튜브의 하단에서 노출되어 튜브에 수십번 권선되어 형성된 양전극부, 상기 튜브의 선단에서 분기되고 상기 양전극부에 대응되는 착탈가능한 음전극부가 삽입된 제3메니홀드, 상기 튜브의선단에서 분기되고 약물 주입과정에서 발생되는 삼출물이 배출되는 제4메니홀드, 상기 튜브의 하단에 공기압에 의해 팽창되도록 형성된 풍선부를 포함하여 이루어진 것을 특징으로 하는 전립선 치료용 카테터를 제공한다.The present invention is a catheter for prostate treatment that is inserted into the urethra to inject drugs into the urethra in order to achieve the object as described above, consisting of an outer tube and an outer tube, the end of the tube formed of a plurality of holes, the end of the tube The first manifold branched from and the drug is injected, the second manifold branched from the front end of the tube, the air is injected from the front end to the lower end of the inside of the tube is exposed from the lower end of the tube is wound around the tube several times A positive electrode portion formed therein, a third manifold branched from the tip of the tube and having a removable negative electrode portion corresponding to the positive electrode portion inserted, a fourth manifold branched from the tip of the tube and discharging the exudates generated during the drug injection process; Characterized in that it comprises a balloon portion formed to be inflated by the air pressure at the bottom of the tube A catheter for prostate treatment is provided.

전술한 바와 같이, 본 발명에 따르면 튜브의 끝에 공기의 압력으로 풍선처럼 부풀어 오르는 풍선부가 형성되어 있어서, 튜브가 요도를 통해 방광까지 삽입된 상태에서 풍선붕에 공기를 불어 넣으면 팽창하여 방광에서 요도로 연결되는 입출부에 풍선부가 걸려 빠져 나가지 못하므로, 약물 주입과정에서 튜브를 인위적으로 잡고 있지 않아도 자중에 의해 튜브가 요도에서 빠져나가지 않는다. 또한, 튜브에 감겨진 전극부를 통해 전립선에 지속으로 전류를 인가함으로 전립선이 전기적인 반응에 의해 약물이 더 잘 흡수되어 약물치료의 시간을 단축하고, 치료효과도 높아진다. 또한 카테터로 전립선 질환 치료를 하면서 성기능 검사도 수행할 수 있다.As described above, according to the present invention, a balloon portion that inflates like a balloon is formed at the end of the tube by the pressure of air, and when the tube is inserted into the bladder with the tube inserted into the bladder through the urethra, the balloon expands and expands from the bladder to the urethra. Since the balloon part is not caught and pulled out to be connected to the entrance and exit, the tube does not escape from the urethra by its own weight even without artificially holding the tube in the drug injection process. In addition, by continuously applying a current to the prostate through the electrode portion wound on the tube, the prostate gland is absorbed by the electrical response to the drug better shorten the time of drug treatment, the therapeutic effect is also high. A catheter can also be used to treat prostate disease, as well as to perform sexual function tests.

첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1에 도시된 바와 같이. 본 발명의 일실시예에 따른 카테터(100)는 요도에 삽입될 정도의 직경을 갖는 중공의 튜브(110)가 구비된다.As shown in FIG. 1. Catheter 100 according to an embodiment of the present invention is provided with a hollow tube 110 having a diameter enough to be inserted into the urethra.

튜브(110)는 폴리에틸렌 재질로서 이중관 형태인 내튜브(120)와 외튜브(130)로 이루어져 있고, 질기고 연성이 좋아 잘 구부려진다.The tube 110 is made of a polyethylene material and consists of an inner tube 120 and an outer tube 130 having a double tube shape, and bends well and has good ductility.

내튜브(120)의 끝부분은 제조할 때 다른 부분보다 얇게 가공하여 공기의 압력이 가해지면 풍선처럼 부풀어 오르게 하는 내튜브풍선부(122)를 형성하고, 내튜브풍선부(122)에 대응되는 외튜브(130)에도 다른 부분보다 얇게 가공하여 외튜브풍선부(132)를 형성하며, 외튜브(130)의 끝 부분에는 다수의 통공이 형성되어 있다.When the end of the inner tube 120 is manufactured to manufacture a thinner than the other portion to form an inner tube balloon portion 122 to swell like a balloon when the air pressure is applied, corresponding to the inner tube balloon portion 122 The outer tube 130 is also processed thinner than other parts to form the outer tube balloon 132, the end portion of the outer tube 130 is formed with a plurality of through holes.

튜브(100)의 선단에는 분기되어 외튜브(130)와 연통되는 제1메니홀드(140)가 형성된다. 제1메니홀드(140)에는 액상의 약물이 투입되어 중공된 외튜브(130)를 따라 이동하다 외튜브(130)의 끝 부분에 형성된 통공(134)을 통해 전립선에 주입된다.A first manifold 140 is formed at the tip of the tube 100 to communicate with the outer tube 130. Liquid drug is injected into the first manifold 140 to move along the hollow outer tube 130 and is injected into the prostate through a through hole 134 formed at the end of the outer tube 130.

튜브(100)의 선단에는 분기되어 내튜브(120)와 연통되는 제2메니홀드(150)가 형성된다. 제2메니홀드(150)에는 공기를 불어 넣어 내튜브(120)의 끝 부분에 형성된 내튜브풍선부(122)에 공기압을 가해 풍선부가 부풀어(팽창) 오르도록 한다.A second manifold 150 is formed at the front end of the tube 100 to communicate with the inner tube 120. Air is blown into the second manifold 150 to apply air pressure to the inner tube balloon 122 formed at the end of the inner tube 120 so that the balloon swells (expands).

내튜브(120)에는 내튜브(120)의 선단에서 부터 하단까지 삽입되어 내튜브(120) 및 외튜브(130)를 통과하여 외튜브(130)에 권선되어 전극코일(182)을 형성하는 양전극부(180)가 형성된다. 양전극부(180)의 선단에는 단자를 형성하여 외부의 배터리 등을 활용하여 전극코일(182)에 통전시킬 수 있도록 한것이다.A positive electrode inserted into the inner tube 120 from the front end to the lower end of the inner tube 120 to pass through the inner tube 120 and the outer tube 130 to be wound around the outer tube 130 to form an electrode coil 182. The unit 180 is formed. A terminal is formed at the tip of the positive electrode unit 180 to allow the electrode coil 182 to be energized by using an external battery.

튜브(100)의 선단에는 분기되어 내튜브(120)와 연통되고 양전극부(180)와 대응되는 음전극부(190)가 삽입되는 제3메니홀드(160)가 형성된다. 제3메니홀드(160)에는 전선이나 와이어로 이루어진 음전극부(190)가 삽입되어 양전극부(180)의 전극코일(182)에 접속되어 전극코일(182)에 일정한 전류를 지속적으로 공급할 수 있는 전기회로를 완성한다. 음전극부(190)는 제3메니홀드(160)에서 착탈 가능하다.A third manifold 160 is formed at the distal end of the tube 100 to communicate with the inner tube 120 and to insert the negative electrode unit 190 corresponding to the positive electrode unit 180. An electric wire capable of continuously supplying a constant current to the electrode coil 182 by inserting a negative electrode portion 190 formed of a wire or a wire into the third manifold 160 is connected to the electrode coil 182 of the positive electrode portion 180. Complete the circuit. The negative electrode unit 190 may be detachable from the third manifold 160.

튜브(100)의 선단에는 분기되어 외튜브(130)와 연통되는 제4메니홀드(170)가 형성된다. 제4메니홀드(170)의 선단에는 첵밸브(도시되지 않음)를 설치하여 필요에 따라 개폐시킴으로써 외튜브(130)를 통해 전립선에 약물을 주입할 때 배출되는 혈액이나 농 등의 삼출물을 필요에 따라 외부로 배출시킬 수 있도록 한 것이다.A fourth manifold 170 is formed at the front end of the tube 100 to communicate with the outer tube 130. At the tip of the fourth manifold 170, a check valve (not shown) is installed and opened and closed as necessary, thereby requiring exudates, such as blood or pus discharged when the drug is injected into the prostate through the outer tube 130. Therefore, it can be discharged to the outside.

내튜브(120)의 하단에는 내튜브(120) 가공시 얇게 가공하여 공기압이 가해지면 풍선처럼 부풀어 오를 수 있게하는 내튜브 풍선부(122)가 폭 1 ~ 2cm 정도로 형성되고, 내튜브 풍선부의 길이는 필요에 따라 가감할 수 있다.At the lower end of the inner tube 120, the inner tube balloon portion 122 is formed to be about 1 to 2 cm in width so as to swell like a balloon when air pressure is applied to the bottom of the inner tube 120, and the length of the inner tube balloon portion is formed. Can be added or subtracted as needed.

외튜브(130)의 하단에는 내튜브 풍선부(122)의 대응되는 위치에 외튜브(130) 가공시 얇게 가공하여 공기압이 가해지면 풍선처럼 부풀어 오를 수 있게하는 외튜브 풍선부(132)가 폭 1 ~ 2cm 정도 형성되고, 외튜브 풍선부(132)의 길이는 필요에 따라 가감할 수 있다.At the lower end of the outer tube 130, the outer tube balloon portion 132, which allows the outer tube 130 to swell like a balloon when air pressure is applied to the corresponding position of the inner tube balloon 122, is expanded. It is formed about 1 ~ 2cm, the length of the outer tube balloon 132 can be added or subtracted as needed.

상기와 같이 구성된 본 발명에 따른 요도 카테터의 작용을 설명하면 다음과 같다.Referring to the operation of the urethral catheter according to the present invention configured as described above are as follows.

튜브(100)의 끝은 요도에 삽입한 후 밀어 넣어 내외튜브 풍선부(122,132)가 방광 내부로 돌출되도록 한다.The end of the tube 100 is inserted into the urethra and then pushed so that the inner and outer tube balloons 122 and 132 protrude into the bladder.

내외튜브 풍선부(122,132)가 방광 내부로 유입된 상태에서 제2메니홀드(150)를 통해 외부에서 공기를 적당히 불어 넣으면 내외튜브 풍선부(122,132)가 부풀어 오르면서 직경이 커져 자중에 의해 빠져나가려고 할 때 방광의 출입구에 걸려 빠져나가지 못하고 고정된다.When the inner and outer tube balloon parts 122 and 132 are introduced into the bladder, the air is properly blown from the outside through the second manifold 150, and the inner and outer tube balloon parts 122 and 132 swell and become larger in diameter, thereby escaped by their own weight. When I try to get there, I get stuck in the entrance of my bladder and I can't get out of it.

내외튜브 풍선부(122,132)가 방광의 출입구에 걸려서 고정되면, 전극코일은 대략 전립선의 중앙에 위치되고, 튜브(100)에 형성된 통공들은 전립선 폭의 전체에 분포되어 위치된다.When the inner and outer tube balloons 122 and 132 are fixed to the entrance and exit of the bladder, the electrode coil is positioned approximately at the center of the prostate gland, and the through holes formed in the tube 100 are distributed and positioned over the entire prostate width.

튜브(100)가 고정된 상태에서 제3메니홀드(160)를 통해 와이어로 이루어진 음전극부(190)을 내튜브(120)로 밀어 넣어 음전극부(190)의 끝이 전극코일(182)의 일측과 접속되도록 한다. 여기서 양전극부(180)에는 배터리가 접속되어 있으므로 배터리의 전류가 전극코일에 통전되어 전극코일(182)부에서는 1 ~ 3V의 전압으로 전류가 방출되어 전립선에 지속적으로 인가된다.In the state where the tube 100 is fixed, the negative electrode unit 190 made of a wire is pushed into the inner tube 120 through the third manifold 160 so that the end of the negative electrode unit 190 is one side of the electrode coil 182. To be connected to. Since the battery is connected to the positive electrode unit 180, the current of the battery is energized by the electrode coil, and the electrode coil 182 emits a current at a voltage of 1 to 3 V and is continuously applied to the prostate.

튜브(100)가 고정되고 전극코일(182)에 전류을 통전시킨 후 제1메니홀드(140)를 통해 액상의 약물을 투입하면 약물은 외튜브(130)를 타고 통공을 통해 전립선에 배출된다. 전립선에 배출된 약물은 전립선에 흡수되면서 치료가 된다.When the tube 100 is fixed and the current flows through the electrode coil 182, the drug is injected into the liquid through the first manifold 140, and the drug is discharged to the prostate through the outer tube 130. Drugs released into the prostate are treated by absorption into the prostate.

도 5는 본 발명에 따른 다른 실시예로서, 풍선부가 상호 일정간격 이격되어 두개 형성된 것이다. 이는 하나의 풍선부는 방광의 출입구에 걸리고 다른 하나는 요도에 강하게 밀착되어 튜브가 빠지지 않으면서도 밀려 올려가지도 않도록 한 것이다.5 is another embodiment according to the present invention, two balloon parts are formed at regular intervals from each other. This is because one balloon is caught in the entrance of the bladder and the other is tightly attached to the urethra so that the tube is not pushed up without being pulled out.
