Description

자궁경부 무력증에서 조산을 방지하기 위한 자궁경부 밴드 구조체Cervical band structure to prevent premature birth in cervical atresia

본 발명은 조산방지 치료제로써 상세하게는 자궁경부의 확장을 막아주고 조산방지 약물을 방출함으로써 조산을 방지하기 위한 장치에 관한 것으로서, 보다 상세하게는 자궁 경부의 크기에 따른 맞춤형 자궁경부 압박 밴드의 구조에 관한 것이다.More particularly, the present invention relates to a device for preventing the cervical dilatation and releasing the anti-prenancy drug, and more particularly, to a device for preventing the premature cervical compression band according to the size of the cervix .

조기양막파수는 조산의 중요한 원인이 되는데 조산으로 인한 신생아의 합병증과 산모 및 태아 사망률은 심각한 문제로서 국내 연구 보고에 의하면 임신 28주의 조산아 생존률이 50%～70%로 학자들마다 차이를 보이고 있다.Premature rupture of membranes is an important cause of prematurity. Complications of prematurity and maternal and fetal mortality are serious problems. According to domestic reports, the survival rate of preterm delivery is 28% and 50% ~ 70%, respectively.

최근에는 조기양막파수의 문제를 해소하기 위하여 파열된 양막 부위를 인위적으로 막아 주는 방법으로서 자궁경부 Fibrin Ceal을 사용하거나 또는 Oeguta Fence를 사용하여 자궁경부를 막아줌으로써 양수의 누출을 방지하는 방법을 사용한다.Recently, a method to prevent the leakage of amniotic membrane by using cervical fibrin ceal or using Oeguta Fence to block the cervix is used as a way to artificially block the ruptured amniotic membrane to resolve the problem of premature rupture of membranes.

한편, 종래에는 자궁경부에 거치하는 페사리라고 하는 장치가 있으나 이는 단순히 자궁경부에 거치하는 장치로 조산효과가 미미하다는 단점이 있다. 기존에는 조산을 막기 위한 질정이 있으나 매일 약물을 본인이 질내 넣어야 하는 불편 등으로 환자의 약물 순응도가 떨어지고 실제 약물이 녹지 않아 그 효과가 감소되는 문제점이 있다.On the other hand, there is a device called a pesary which is conventionally placed on the cervix, but it has a disadvantage in that it is merely a device for resting on the cervix and the effect of preterm birth is minimal. In the past, there is a fear of preventing premature birth, but there is a problem that the drug is not dissolved due to the inconvenience that the patient has to insert the drug into the vagina every day, and the effect is reduced because the drug is not dissolved.

조산 예방을 위한 방안을 개시한 종래의 문헌으로는 등록특허 제10-0365006호를 들 수 있는데, 상기 문헌은 자궁경부에 삽입 고정되는 자궁경부캡을 통해 자궁경부의 내벽과의 저항이 최대화되도록 하여 자궁경부캡의 고정 위치에서 양막강 측으로 끌려들어가지 않게 하는 구조 및 캐티터의 슬라이드 이동 가능한 구조를 제공하는 것으로서 자궁경부 상에 조절 가능하게 안정적으로 고정되는 형태로서 조산방지 약물을 공급하는 방안에 대해서는 별도로 개시하지 않는다는 한계가 있다.A conventional document disclosing a method for prevention of premature birth is that of Patent Registration No. 10-0365006, which maximizes the resistance of the uterine cervix to the inner wall of the cervix through a cervical cap inserted and fixed in the cervix The present invention provides a structure for preventing sliding of the catheter from the fixed position of the cervical cap, and a structure for sliding movement of the catheter, which can be stably and stably fixed on the cervix, There is a limitation that it is not separately disclosed.

이하, 도 6 내지 도 8을 참조하여, 본 발명의 실시예에 따라 자궁경부 밴드 구조체를 설명한다.Hereinafter, a cervical band structure according to an embodiment of the present invention will be described with reference to FIGS. 6 to 8. FIG.

본 발명에 따른 자궁경부 밴드 구조체는 플렉서블한 재질을 갖는 밴드 바디(110), 밴드 바디(110) 내에 신축 가능하게 삽입되는 탄력 링(120), 밴드 바디(110) 내측에 형성되는 혈관 손상방지 홈(130), 밴드 바디(110) 내측에 돌출 형성되는 미끄럼 방지 엠보싱(140), 및 밴드 바디(110) 상에 형성되는 약물 방출부(150)를 포함한다.The cervical band structure according to the present invention includes a band body 110 having a flexible material, a resilient ring 120 elastically inserted into the band body 110, An anti-slip emboss 140 protruding from the inside of the band body 110, and a drug discharging part 150 formed on the band body 110.

상기 밴드 바디(110)는 자궁경부의 확장을 막아주는 밴드 형태의 실리콘 재질로서, 그 길이 방향을 따라 탄력 링(120)이 삽입될 수 있도록 관통 형성되어진다.The band body 110 is a band-shaped silicone material that prevents the cervix from expanding, and is formed so that the elastic ring 120 can be inserted along the longitudinal direction of the band body 110.

밴드 바디(110)는 그 일측이 분리된 구조를 이루게 되는데, 상기 분리된 부분 상에 결합 돌기(112) 및 결합홈(114)이 형성된다. 밴드 바디(110) 내부를 통해 설치되는 탄력 링(120)은 일예로서 결합 돌기(112)에 고정된 상태일 수 있다.  The band body 110 has a structure in which one side is separated, and a coupling protrusion 112 and a coupling groove 114 are formed on the separated portion. The elastic ring 120 installed through the inside of the band body 110 may be fixed to the coupling protrusion 112 as an example.

상기 구조를 통해서, 사용자가 결합 돌기(112) 및 결합홈(114)을 통해서 상기 밴드 바디(110)의 일측을 분리하는 경우에 탄력 링(120)을 통해서 신축 가능한 상태를 갖게 한다.Through the above structure, when the user separates one side of the band body 110 through the coupling projections 112 and the coupling grooves 114, the user can stretch and contract through the elastic rings 120.

도 8을 참조하는 경우에, 밴드 바디(110)의 내면은 상부에서 하부 방향으로 경사지게 형성된 구조일 수 있다. 즉, 밴드 바디(110)의 내측 상단부에 돌출부(116)가 구성됨으로써 상부에서 하부 방향으로 갈수록 밴드 바디(110)의 내경이 점점 커지거나 좁아지는 구조일 수 있다. 상기 구조 하에서는 자궁경부 밴드 구조체가 자궁경부 상에 결합된 경우에 내경이 좁은 부분이 자궁경부의 외측 상에 배치되게 함으로써 자궁경부 밴드 구조체의 분리를 방지하게 할 수 있다.Referring to FIG. 8, the inner surface of the band body 110 may have a structure inclined downward from the top. That is, since the protrusion 116 is formed on the inner upper end of the band body 110, the inner diameter of the band body 110 gradually increases or decreases from the upper portion to the lower portion. Under such a structure, when the cervical band structure is bonded on the cervix, the narrow inner diameter portion is disposed on the outer side of the cervix, thereby preventing the cervical band structure from being separated.

혈관 손상방지 홈(130)은 밴드 바디(110) 내측에 대향하는 형태로 형성되며, 자궁경부 밴드 구조체를 자궁경부 상에 결합한 경우에 양측 자궁경부혈관의 손상을 막기 위한 구조일 수 있다.The vascular injury-preventing groove 130 is formed in a shape opposite to the inside of the band body 110 and may be a structure for preventing damage to the bilateral cervical vessels when the cervical band structure is bonded on the cervix.

미끄럼 방지 엠보싱(140)은 밴드 바디(110)의 마주보는 양측 상에서 돌출 형성되는 구조일 수 있는데, 예를 들어 자궁경부에 대한 손상을 최대한 방지하도록 반구 형태의 구조를 이룰 수 있다.The anti-slip embossing 140 may be a structure protruding from opposite sides of the band body 110, for example, a hemispherical structure may be formed to prevent damage to the cervix as much as possible.

상기 미끄럼 방지 엠보싱(140) 및 혈관 손상방지 홈(130)은 밴드 바디(110) 상에서 상호 간섭을 회피할 수 있도록 배치된다. 즉, 혈관 손상방지 홈(130)이 밴드 바디(110)의 중심으로 기준으로 대향하는 형태로 배치된 이후에, 미끄럼 방지 엠보싱(140)은 상기 혈관 손상방지 홈(130)이 형성된 위치를 피한 상태에서 밴드 바디(110)의 중심으로 기준으로 대향하는 형태로 배치된다.The anti-slip embossing 140 and the vascular damage-preventing groove 130 are disposed on the band body 110 so as to avoid mutual interference. The anti-slip embossing 140 may be formed in a state in which the position where the blood vessel damage prevention groove 130 is formed is avoided after the anti-slip prevention groove 130 is disposed opposite to the center of the band body 110 With respect to the center of the band body 110.

약물 방출부(150)는 밴드 바디(110)의 외측 표면 중앙부 상에서 길이 방향을 따라 설치되는 구조일 수 있다. 즉, 링 형상을 갖는 밴드 바디(110)의 외주면 최외측을 따라 형성되는 구조일 수 있다. 본 약물 방출부(150)는 서방형 프로게스테론 방출 장치 기능을 하는 장치로서 기능하고, 방출되는 약물은 조산방지 치료제로써 자궁경부의 확장을 막아주고 조산을 방지하는 기능을 한다.The drug releasing part 150 may be provided along the longitudinal direction on the center of the outer surface of the band body 110. That is, it may be formed along the outermost side of the outer circumference of the ring-shaped band body 110. The drug releasing part 150 functions as a device for functioning as a sustained progesterone releasing device, and the released drug serves as an antihypertensive drug to prevent expansion of the cervix and prevent premature birth.
