다단 구조의 피스톤이 형성된 체내 액체 투여기In-vivo liquid dispenser with multistage piston
아래의 실시예들은 다단 구조의 피스톤이 형성된 체내 액체 투여기에 관한 것으로, 더욱 상세하게는 재사용이 불가능한 다단 구조의 피스톤이 형성된 체내 액체 투여기에 관한 것이다. The following embodiments relate to an intrabody liquid dispenser having a multistage piston, and more particularly, to an intrabody liquid dispenser having a multistage piston that is not reusable.
일반적으로 치료 및 위생 등의 목적으로 여성의 질(膣, vagina) 또는 항문 내에 용액 형태의 치료약, 세척 용액 등을 투여할 수 있다. 예를 들어, 여성의 질 세척을 위한 세척 용액을 투여, 피임을 위한 용액 형태의 피임약을 투여, 또는 치질, 성병 등의 치료를 위한 용액 형태의 치료약을 투여, 및 성교 시의 윤활제 투여 등 그 활용 양태는 매우 다양하다. 여성의 질 또는 항문은 점막이 노출되는 부분으로 세균의 감염이 쉬우므로 체내 액체 투입 시 청결에 각별한 주의를 기울여야 한다. In general, for the purpose of treatment and hygiene, a woman may be administered a therapeutic drug, a washing solution, or the like in the form of vagina or anus. For example, administration of a washing solution for washing the vagina of a woman, a contraceptive pill in the form of contraception, or a therapeutic drug in the form of a solution for the treatment of hemorrhoids, sexually transmitted diseases, etc., and administration of a lubricant during sexual intercourse. Aspects are very diverse. The vagina or anus of the woman is an area where the mucous membrane is exposed, so bacterial infections are easy.
이러한 체내 액체 투여기는 위생 상의 문제 및 세척의 어려움으로 인해 일회용으로 제작되는 경우가 많으며, 이에 따라 내부에 액체가 미리 수용된 상태로 시중에 판매되고 있다. Such intrabody liquid dispensers are often manufactured for single use due to hygiene problems and difficulty in cleaning, and thus are sold on the market with liquids already contained therein.
그러나 사용자에 따라 일회용의 체내 액체 투여기를 임의로 세척하여 재사용하는 경우가 있어 질병 및 세균의 감염의 위험성이 매우 높은 실정이다. 따라서 이와 같은 체내 액체 투여기는 재사용이 불가능하도록 설계될 필요가 있다.However, depending on the user, the disposable body liquid dispenser may be arbitrarily washed and reused, so the risk of disease and bacterial infection is very high. Thus, such intrabody liquid dispensers need to be designed such that they cannot be reused.
한국공개특허 10-2003-0028796호는 이러한 여성 질 세척기에 관한 것으로, 길이가 긴 노즐 주사기를 이용하여 체내 세척 및 살균 가능한 기술을 기재하고 있다. Korean Patent Laid-Open No. 10-2003-0028796 relates to such a female vaginal washer and describes a technique capable of washing and sterilizing the body using a long nozzle syringe.

Embodiments provide a liquid injector in which a piston of a multi-stage structure is formed that is not reusable because the piston body and the pressing member are separated and only the pressing member is moved backward when tension occurs after the piston is moved forward for liquid injection.
실시예들은 바디와 피스톤이 수용되고 내측에 바디의 액체 분사구에 삽입되는 마개가 형성된 케이스를 제공함으로써 별도의 케이스 없이 위생적으로 보관이 가능한 다단 구조의 피스톤이 형성된 체내 액체 투여기를 제공하는데 있다.

그리고 바디(110)의 후단부에는 받침부(112)가 연결될 수 있다. 이때, 받침부(112)는 별도의 부재로 이루어져 바디(110)의 후단부에 결합되거나 바디(110)와 일체형으로 이루어질 수 있다. And the supporting portion 112 may be connected to the rear end of the body 110. At this time, the support portion 112 is made of a separate member may be coupled to the rear end of the body 110 or integrally formed with the body 110.
받침부(112)는 내부 관통구가 형성되며 일측이 바디(110)의 후단부에 연결되고, 타측이 후술할 피스톤(120)과 연결된다. The supporting portion 112 is formed with an inner through hole and one side is connected to the rear end of the body 110, the other side is connected to the piston 120 to be described later.
받침부(112)의 표면에는 일정 영역 볼록 패턴 또는 오목 패턴 등의 소정의 패턴을 가져 사용자에 의해 파지 시 미끄러지는 것을 방지할 수 있다. 예컨대 볼록 패턴 및/또는 오목 패턴은 다수의 링 형상, 나선형 형상, 도트 형상, 스트라이프 형상, 엠보싱 형상 중 어느 하나일 수 있다. The surface of the base portion 112 may have a predetermined pattern such as a convex pattern or a concave pattern in a predetermined region to prevent slippage when held by a user. For example, the convex pattern and / or the concave pattern may be any one of a plurality of ring shapes, spiral shapes, dot shapes, stripe shapes, and embossed shapes.
일례로 받침부(112)의 표면에 길이 방향으로 나열된(즉, 길이 방향과 수직하게 형성된) 다수의 링 형상의 패턴이 형성될 수 있으며, 이러한 다수의 링 형상의 패턴은 굴곡이 형성되어 볼록부와 오목부를 가질 수 있다. 다른 예로, 받침부(112)의 표면에 볼록 형성된 다수의 도트 패턴이 형성될 수 있다. 또 다른 예로, 받침부(112)의 표면에 길이 방향으로 형성된 스트라이프 형상의 패턴이 형성될 수 있으며, 이러한 스트라이프 형상의 패턴은 굴곡이 형성되어 볼록부와 오목부를 가질 수 있다. 또 다른 예로, 받침부(112)의 표면에 벌집 엠보싱 형상의 패턴이 형성될 수 있다. For example, a plurality of ring-shaped patterns arranged in the longitudinal direction (that is, formed perpendicularly to the longitudinal direction) may be formed on the surface of the support part 112, and the plurality of ring-shaped patterns may have curved portions to form convex portions. And a recess. As another example, a plurality of dot patterns may be formed on the surface of the base 112. As another example, a stripe-shaped pattern formed in the longitudinal direction may be formed on the surface of the base 112, and the stripe-shaped pattern may have a convex portion and a concave portion formed by bending. As another example, a honeycomb embossed pattern may be formed on the surface of the base 112.
이와 같이 받침부(112)의 표면에 일정한 패턴이 형성되어 사용자가 체내 액체 투여를 위해 바디(110)의 받침부(112)를 파지할 때 사용자의 손이 미끄러지는 것을 방지할 수 있다. As such, a predetermined pattern is formed on the surface of the support part 112 to prevent the user's hand from slipping when the user grips the support part 112 of the body 110 to administer the liquid in the body.
더욱이, 받침부(112)는 외주면이 소정 형상으로 이루어져 파지 시 미끄러짐을 방지할 수 있다. 예를 들어, 받침부(112)는 원통 형상의 내부 관통구가 형성되고 외주면은 다각기둥 형상으로 이루어질 수 있다. 즉, 받침부(112)는 원통 형상의 내부 관통구가 형성되고 외주면은 삼각기둥 형상, 사각기둥 형상, 오각기둥 형상, 육각기둥 형상, 칠각기둥 형상, 팔각기둥 형상 등으로 이루어질 수 있다. 또한, 받침부(112)는 다각기둥 형상의 내부 관통구가 형성되고 외주면 또한 다각기둥 형상으로 이루어질 수 있다. 예컨대, 받침부(112)는 육각기둥 형상으로 이루어지고 육각기둥 형상의 내부 관통구를 가질 수 있다. In addition, the support 112 has an outer circumferential surface of a predetermined shape to prevent slipping when gripping. For example, the base portion 112 may be formed with a cylindrical inner through hole and the outer circumferential surface may have a polygonal column shape. That is, the base 112 has a cylindrical inner through-hole is formed and the outer peripheral surface may be made of a triangular prism shape, square pillar shape, pentagonal pillar shape, hexagonal pillar shape, heptagonal pillar shape, octagonal pillar shape and the like. In addition, the base portion 112 may be formed in the inner through-hole of the polygonal pillar shape and the outer peripheral surface may also be formed in a polygonal pillar shape. For example, the base portion 112 may have a hexagonal pillar shape and may have an inner through hole having a hexagonal pillar shape.
이러한 받침부(112)의 외주면은 바디(110)의 둘레보다 큰 둘레를 가져 일측에 상부 케이스(130)가 결합되며 타측에 하부 케이스(140)가 결합될 수 있다. 이는 아래에서 더 구체적으로 설명한다. The outer circumferential surface of the support 112 has a larger circumference than the body 110, the upper case 130 is coupled to one side, and the lower case 140 may be coupled to the other side. This is described in more detail below.
피스톤(120)은 바디(110)의 개방된 후단부로 삽입되어 바디(110)의 전단부로 전진이 가능하다. 피스톤(120)의 재질은 합성수지로 이루어질 수 있으나, 이에 제한되지는 않는다. The piston 120 is inserted into the open rear end of the body 110 to be advanced to the front end of the body 110. The material of the piston 120 may be made of synthetic resin, but is not limited thereto.
피스톤(120)은 바디(110)의 개방된 후단부로 삽입되어 가압에 의해 전방으로 이동 시, 액체 수용 공간에 수용된 액체(l)를 액체 분사구(111)를 통해 외부로 분사시킨다. When the piston 120 is inserted into the open rear end of the body 110 and moves forward by pressure, the piston 120 injects the liquid l contained in the liquid accommodation space to the outside through the liquid injection hole 111.
더 구체적으로 피스톤(120)은 피스톤 본체(122) 및 누름 부재(124, 125, 126)를 포함하여 이루어질 수 있으며, 누름 부재(124, 125, 126)는 제1 누름 부재(124), 제2 누름 부재(125), 및 제3 누름 부재(126)로 이루어질 수 있다. More specifically, the piston 120 may include the piston body 122 and the pressing members 124, 125, and 126, and the pressing members 124, 125, and 126 may include the first pressing member 124 and the second. The pressing member 125 and the third pressing member 126 may be formed.
먼저, 누름 부재(124, 125, 126)는 받침부(112)의 타측에 연결되며 다단 구조로 이루어져 후단부에 형성된 누름대(127)를 누름에 따라 순차적으로 전방으로 이동되어 받침부(112) 내에 수용된다. First, the pressing members (124, 125, 126) is connected to the other side of the supporting portion 112 and consists of a multi-stage structure is sequentially moved forward by pressing the pressing stand 127 formed in the rear end supporting portion 112 Is housed within.
그리고, 피스톤 본체(122)는 누름 부재(124, 125, 126)가 순차적으로 전방으로 이동됨에 따라 바디(110)의 개방된 후단부로 삽입되어 전방으로 이동 시 액체 수용 공간에 수용된 액체(l)를 액체 분사구(111)를 통해 외부로 분사시킨다. 피스톤 본체(122)는 전방으로 이동 후 장력이 발생하는 경우에 후방으로 이동이 제한되어 재사용이 불가능하다. In addition, the piston body 122 is inserted into the open rear end of the body 110 as the pressing members 124, 125, and 126 are sequentially moved forward to move the liquid l contained in the liquid receiving space when moving forward. It is injected to the outside through the liquid injection port 111. The piston body 122 is limited in movement in the rear when the tension occurs after moving forward, and thus cannot be reused.
이러한 피스톤 본체(122)는 전단부에 패킹부(121)가 형성되어 가압에 따라 바디(110)에 밀착되어 전진함으로써 바디(110) 내에 수용된 액체(l)를 액체 분사구(111)를 통해 외부로 분사시킬 수 있다. The piston body 122 is the packing portion 121 is formed in the front end portion is in close contact with the body 110 in accordance with the pressure to move forward the liquid (1) contained in the body 110 through the liquid injection port 111 to the outside Can be sprayed.
더욱이 피스톤 본체(122)는 후방으로의 이동을 제한하기 위해 바디(110)의 길이보다 짧게 형성될 수 있다. 피스톤 본체(122)는 바디(110)에 삽입되어 전방으로 최대 이동 시 끝단이 바디(110) 내에 수용됨으로써, 사용자가 임의로 피스톤 본체(122)를 바디(110)로부터 분리시키거나 피스톤 본체(122)를 후방으로 이동시키는 것을 방지할 수 있다. 즉, 피스톤 본체(122)를 후방으로 이동시키지 못하게 함으로써 사용자 임의로 재사용되는 것을 방지할 수 있다. Furthermore, the piston body 122 may be formed shorter than the length of the body 110 to limit the movement to the rear. The piston body 122 is inserted into the body 110 so that the end is accommodated in the body 110 when the maximum movement forward, so that the user can arbitrarily separate the piston body 122 from the body 110 or the piston body 122 Can be prevented from moving backward. That is, by preventing the piston body 122 from moving backward, it can be prevented from being reused arbitrarily.
실시예에 따라 다단 구조의 피스톤이 형성된 체내 액체 투여기(100)는 상부 케이스(130) 및 하부 케이스(140)를 더 포함할 수 있으며, 마개와 케이스가 일체로 형성되어 별도의 파우치 등의 케이스를 구비할 필요가 없도록 할 수 있다. According to an embodiment, the body liquid dispenser 100 having a piston having a multi-stage structure may further include an upper case 130 and a lower case 140. A case such as a separate pouch is formed integrally with a stopper and a case. It may not be necessary to have a.
상부 케이스(130)는 바디(110)의 적어도 일부를 수용하는 것으로, 그 재질에 제한은 없으나 합성수지로 이루어질 수 있다. The upper case 130 accommodates at least a portion of the body 110, but is not limited in material but may be made of synthetic resin.
상부 케이스(130)는 후단부가 개방된 길이가 긴 유선형, 원통형, 또는 사각기둥 형상으로 이루어져 내부에 바디(110)를 수용할 수 있다. 이러한 상부 케이스(130)는 받침부(112)의 일측에 결합될 수 있다. 이때 상부 케이스(130)의 끝단에 걸림홈(132)이 형성될 수 있으며, 예컨대 걸림홈(132)은 링 형상의 홈일 수 있다. 한편, 받침부(112)의 전측에 링 형상으로 돌출된 걸림돌기(113)가 형성되어 걸림홈(132)에 결합됨으로써 받침부(112)에 상부 케이스(130)가 결합될 수 있다.The upper case 130 is formed of a long streamlined, cylindrical, or square pillar shape with the rear end opened to accommodate the body 110 therein. The upper case 130 may be coupled to one side of the base 112. At this time, the locking groove 132 may be formed at the end of the upper case 130, for example, the locking groove 132 may be a ring-shaped groove. Meanwhile, the upper case 130 may be coupled to the support part 112 by being coupled to the locking groove 132 by a locking protrusion 113 protruding in a ring shape on the front side of the support part 112.
여기에서는 상부 케이스(130)가 받침부(112)의 일측에 결합되는 것으로 도시 및 설명하고 있으나, 상부 케이스(130)는 바디(110) 및 받침부(112)의 전체를 수용하도록 구성될 수도 있다. Here, although the upper case 130 is illustrated and described as being coupled to one side of the base portion 112, the upper case 130 may be configured to accommodate the entire body 110 and the base portion 112. .
한편, 상부 케이스(130)의 전단부 내측에는 마개(131)가 돌출 형성되어 바디(110)의 액체 분사구(111)에 삽입됨으로써, 바디(110)의 액체 수용 공간에 수용된 액체(l)가 사용자의 의도와 상관 없이 외부로 유출되는 것을 방지할 수 있다. On the other hand, the stopper 131 is formed to protrude inside the front end of the upper case 130 is inserted into the liquid injection port 111 of the body 110, the liquid (1) accommodated in the liquid receiving space of the body 110 is user It can be prevented from leaking to the outside regardless of the intention.
이 경우, 별도의 마개를 사용하지 않아 간편할 뿐만 아니라 마개만 별도 형성되는 경우 바디(110)로부터 마개가 쉽게 분리되어 액체(l)가 유출되는 현상을 사전에 방지할 수 있다.In this case, it is not only easy to use a separate stopper, but when only the stopper is formed separately, the stopper can be easily separated from the body 110 to prevent a phenomenon in which the liquid l leaks.
더욱이 상부 케이스(130)의 내부에 부드러운 재질의 스폰지 등이 구성되어 체내에 삽입되는 바디(110)에 스크래치가 생기는 것을 방지함으로써, 보다 안전하게 바디(110)를 보호할 수도 있다. 특히, 상부 케이스(130)의 내부에 스폰지 등의 부드러운 재질로 구성되어 스크래치의 발생을 방지하는 내부층이 형성될 수도 있다. In addition, a soft sponge or the like is formed inside the upper case 130 to prevent scratches on the body 110 inserted into the body, thereby protecting the body 110 more safely. In particular, the inner layer of the upper case 130 may be formed of a soft material such as a sponge to prevent the occurrence of scratches.
하부 케이스(140)는 피스톤(120)의 적어도 일부를 수용하는 것으로, 그 재질에 제한은 없으나 합성수지로 이루어질 수 있다.The lower case 140 accommodates at least a portion of the piston 120, but is not limited in material, but may be made of synthetic resin.
하부 케이스(140)는 전단부가 개방된 길이가 긴 유선형, 원통형, 또는 사각기둥 형상으로 이루어져 내부에 피스톤(120)의 적어도 일부 또는 전체를 수용할 수 있다. 이러한 하부 케이스(140)는 받침부(112)의 타측에 결합될 수 있다. 이때 하부 케이스(140)의 끝단에 걸림돌기(141)이 형성될 수 있으며, 예컨대 걸림돌기(141)는 링 형상의 돌기일 수 있다. 한편, 받침부(112)의 내측에 링 형상으로 걸림홈(115)이 형성되어 걸림돌기(141)가 결합됨으로써 받침부(112)에 하부 케이스(140)가 결합될 수 있다.The lower case 140 may be formed of a long streamlined, cylindrical, or square pillar shape having an open front end portion to accommodate at least part or the entirety of the piston 120 therein. The lower case 140 may be coupled to the other side of the base 112. In this case, a locking protrusion 141 may be formed at an end of the lower case 140, and for example, the locking protrusion 141 may be a ring-shaped protrusion. On the other hand, the locking groove 115 is formed in a ring shape inside the support portion 112 so that the locking protrusion 141 is coupled to the lower case 140 may be coupled to the support portion 112.
더욱이 하부 케이스(140)의 내부에 부드러운 재질의 스폰지 등이 구성되어 피스톤(120)에 스크래치가 생기는 것을 방지할 수 있다. 특히, 하부 케이스(140)의 내부에 스폰지 등의 부드러운 재질로 구성된 내부층이 형성될 수도 있다. In addition, a soft sponge or the like may be formed inside the lower case 140 to prevent scratches on the piston 120. In particular, an inner layer made of a soft material such as a sponge may be formed inside the lower case 140.

It can be moved forward. In this case, the third pressing member 126 may move the piston body 122 coupled to the front end to the front, thereby injecting the liquid l inside the body 110 to the outside. Here, the third pressing member 126 may move forward when pressed and may be accommodated in the second pressing member 125, and may be caught by a jaw or an inner circumferential surface formed at the rear end of the body 110 to limit further advancement. can do.
피스톤 본체(122)는 제1 누름 부재(124), 제2 누름 부재(125), 및 제3 누름 부재(126)가 순차적으로 전방으로 이동됨에 따라 바디(110)의 개방된 후단부로 삽입되어 전방으로 이동된다. The piston body 122 is inserted into the opened rear end of the body 110 as the first pressing member 124, the second pressing member 125, and the third pressing member 126 are sequentially moved forward, thereby being forward. Is moved to.
이러한 피스톤 본체(122)는 전단부에 패킹부(121)가 형성되어 가압에 따라 바디(110)에 밀착되어 전진함으로써 바디(110) 내에 수용된 액체(l)를 액체 분사구(111)를 통해 외부로 분사시킬 수 있다. The piston body 122 is the packing portion 121 is formed in the front end portion is in close contact with the body 110 in accordance with the pressure to move forward the liquid (1) contained in the body 110 through the liquid injection port 111 to the outside Can be sprayed.
특히, 피스톤(120)은 피스톤 본체(122)의 후단부에 돌출부(123)가 형성되고, 제3 누름 부재(126)의 전단부에 돌출부(123)가 삽입된 홈부가 형성되어 누름대(127)의 가압 시 제3 누름 부재(126)가 전방으로 이동되어 피스톤 본체(122)를 전방으로 이동시킬 수 있다. 이때, 누름대(127)에 장력이 발생되는 경우 홈부에 삽입된 돌출부(123)가 분리되고 누름 부재(124, 125, 126)만 후방으로 이동됨으로써 피스톤 본체(122)의 후방 이동이 제한되어 재사용이 불가능하다. In particular, the piston 120 has a protrusion 123 formed at the rear end of the piston body 122, and a groove portion in which the protrusion 123 is inserted at the front end of the third pressing member 126 is formed to press the push rod 127. The third pressing member 126 may be moved forward when the) is pressed to move the piston body 122 forward. At this time, when tension is generated in the presser 127, the protrusion 123 inserted into the groove is separated, and only the pressing members 124, 125, and 126 are moved backwards, thereby restricting the rearward movement of the piston body 122 and reusing it. This is impossible.
한편, 제1 누름 부재(124), 제2 누름 부재(125), 및 제3 누름 부재(126)는 걸림돌기 등에 의해 서로 결합되어 전진 또는 후진이 가능하며, 전진으로 최대 이동 시 서로 겹쳐진 상태로 받침부(112) 내에 배치될 수 있다. On the other hand, the first pressing member 124, the second pressing member 125, and the third pressing member 126 are coupled to each other by a locking projection or the like to move forward or backward, in the state of overlapping each other when moving forward It may be disposed in the base 112.
더욱이 피스톤 본체(122)는 후방으로의 이동을 제한하기 위해 바디(110)의 길이보다 짧게 형성될 수 있다. 피스톤 본체(122)는 바디(110)에 삽입되어 전방으로 최대 이동 시 끝단이 바디(110) 내에 수용됨으로써, 사용자가 임의로 피스톤 본체(122)를 바디(110)로부터 분리시키거나 피스톤 본체(122)를 후방으로 이동시키는 것을 방지할 수 있다. 즉, 피스톤 본체(122)를 후방으로 이동시키지 못하게 함으로써 사용자 임의로 재사용되는 것을 방지할 수 있다. Furthermore, the piston body 122 may be formed shorter than the length of the body 110 to limit the movement to the rear. The piston body 122 is inserted into the body 110 so that the end is accommodated in the body 110 when the maximum movement forward, so that the user can arbitrarily separate the piston body 122 from the body 110 or the piston body 122 Can be prevented from moving backward. That is, by preventing the piston body 122 from moving backward, it can be prevented from being reused arbitrarily.
따라서 일 실시예에 따른 다단 구조의 피스톤이 형성된 체내 액체 투여기(100)는 피스톤 본체(122)의 후단부에 돌출부(123)가 형성되고, 제3 누름 부재(126)의 전단부에 돌출부(123)가 삽입된 홈부가 형성되어 누름대(127)의 가압 시 제3 누름 부재(126)가 전방으로 이동되어 바디(110) 내에서 피스톤 본체(122)를 전방으로 이동시킴으로써 바디(110) 내부의 액체(111)를 외부로 분사시킬 수 있다. 이후, 피스톤(120)의 누름대(127)에 장력이 발생되는 경우 홈부에 삽입된 돌출부(123)가 분리됨으로써 누름 부재(124, 125, 126)만 후방으로 이동되고 피스톤 본체(122)의 후방 이동이 제한되어 재사용이 불가능하다. Therefore, in the body liquid dispenser 100 having the piston having a multi-stage structure according to an embodiment, a protrusion 123 is formed at a rear end of the piston body 122, and a protrusion ( The groove portion into which the 123 is inserted is formed so that the third pressing member 126 is moved forward when the pressing stand 127 is pressed to move the piston body 122 forward in the body 110 to thereby move the inside of the body 110. Liquid 111 may be injected to the outside. Subsequently, when tension is generated in the presser 127 of the piston 120, the protrusion 123 inserted into the groove is separated, so that only the pressing members 124, 125, and 126 are moved backwards, and the rear of the piston body 122 is moved. The movement is limited and cannot be reused.

더 구체적으로, 제1 누름 부재(225)는 받침부(212)의 내측에 결합되고, 내부 관통구가 형성된 사각기둥 형상 또는 원기둥 형상으로 이루어져 가압 시 전방으로 이동되어 받침부(212)의 내벽을 따라 전방으로 이동될 수 있다. More specifically, the first pressing member 225 is coupled to the inside of the support portion 212, made of a rectangular column shape or a cylindrical shape having an inner through hole is moved forward when pressed to the inner wall of the support portion 212 Can be moved forward.
그리고 제2 누름 부재(223)는 제1 누름 부재(225)의 내측에 결합되어 끝단의 누름대의 가압 시 제1 누름 부재(225)의 내벽을 따라 전방으로 이동되며 피스톤 본체(222)와 연결되어 피스톤 본체(222)를 전방으로 이동시킬 수 있다. 여기에서 제2 누름 부재(223)의 후단부는 슬릿(224)에 의해 이격된 날개부(223a)가 형성되어 날개부(223a)가 압축된 상태로 제1 누름 부재(225)에 슬라이드된 후, 제1 누름 부재(225)에 형성된 홈부(226)에서 팽창되어 후방으로의 이동이 제한될 수 있다. In addition, the second pressing member 223 is coupled to the inside of the first pressing member 225 and moves forward along the inner wall of the first pressing member 225 when the end of the presser is pressed and is connected to the piston body 222. The piston body 222 may be moved forward. Here, the rear end portion of the second pressing member 223 is formed by the wing portion 223a spaced apart by the slit 224 and slides on the first pressing member 225 while the wing portion 223a is compressed. The expansion in the groove 226 formed in the first pressing member 225 may be limited to move backward.
예를 들어 피스톤 본체(222)의 후단부에 제2 누름 부재(223)가 형성되고, 제2 누름 부재(223)의 외주면에는 슬릿(224)에 의해 소정 간격 이격된 날개부(223a)가 형성될 수 있다. 이러한 제2 누름 부재(223)의 외측에 제1 누름 부재(225)가 형성되며, 사용자가 제2 누름 부재(223)를 가압하는 경우 제2 누름 부재(223)는 제1 누름 부재(225)의 내측에서 슬라이드 되어 전방으로 이동될 수 있다. For example, a second pressing member 223 is formed at the rear end of the piston body 222, and a wing portion 223a spaced by a slit 224 at a predetermined interval is formed on the outer circumferential surface of the second pressing member 223. Can be. The first pressing member 225 is formed outside the second pressing member 223, and when the user presses the second pressing member 223, the second pressing member 223 may be the first pressing member 225. The inner side of the slide can be moved forward.
이때, 제1 누름 부재(225)의 전단부 내측에 홈부(226)이 형성되어 제2 누름 부재(223)가 소정 거리 전방으로 이동된 후 상기의 홈부(226)에 걸림으로써 후방으로의 이동을 제한할 수 있다. 특히, 제2 누름 부재(223)의 외주면에 형성된 날개부(223a)가 압축된 상태로 제1 누름 부재(225)의 내측에 삽입되어 슬라이드된 후, 링 형상의 홈부(226)에 진입하게 되는 경우 공간이 생겨 압축되어 있던 날개부(223a)가 슬릿(224)에 의해 외측으로 팽창된다. 이와 같이 제2 누름 부재(223)의 외주면에 형성된 날개부(223a)는 팽창되므로 홈부(226) 내에 삽입 후 후방으로의 이동이 제한된다. At this time, the groove portion 226 is formed inside the front end portion of the first pressing member 225 and the second pressing member 223 is moved forward by a predetermined distance, and then the rear portion is moved by catching the groove portion 226. You can limit it. In particular, the wing 223a formed on the outer circumferential surface of the second pressing member 223 is inserted into the inside of the first pressing member 225 in the compressed state and slides, and then enters the ring-shaped groove 226. In this case, a space is created and the wing 223a, which has been compressed, is expanded outwardly by the slit 224. As described above, since the wing 223a formed on the outer circumferential surface of the second pressing member 223 is expanded, movement of the wing 223a after insertion into the groove 226 is limited.
또한, 제1 누름 부재(225)는 받침부(212)의 내측에서 슬라이드 되어 전방으로 이동될 수 있다. 이때 받침부(212)의 전단부 내측에 돌출부(214)가 형성되어 제1 누름 부재(225)의 전방으로의 이동을 제한할 수 있다. In addition, the first pressing member 225 may slide inward of the support 212 and move forward. In this case, the protrusion 214 may be formed inside the front end of the supporting part 212 to limit the forward movement of the first pressing member 225.
다시 말하면, 사용자가 제2 누름 부재(223)를 가압하는 경우 제2 누름 부재(223)는 제1 누름 부재(225)의 내측에서 슬라이드 되어 전방으로 이동되며, 제1 누름 부재(225)는 받침부(212)의 내측에서 슬라이드 되어 전방으로 이동될 수 있다. 이때 받침부(212)의 전단부 내측에 형성된 돌출부(214)에 의해 제1 누름 부재(225)는 소정 거리 이상 전방으로의 이동이 제한되며, 제1 누름 부재(225)의 전단부 내측에 형성된 홈부(226)에 의해 제2 누름 부재(223)는 소정 거리 이상 전방으로 이동된 후 후방으로의 이동이 제한될 수 있다. In other words, when the user presses the second pressing member 223, the second pressing member 223 slides inward of the first pressing member 225 to move forward, and the first pressing member 225 is supported. The inside of the portion 212 can be slid to move forward. At this time, the first pressing member 225 is limited to move forward by a predetermined distance or more by the protrusion 214 formed inside the front end of the supporting part 212, and is formed inside the front end of the first pressing member 225. After the second pressing member 223 is moved forward by a predetermined distance or more by the groove 226, movement of the second pressing member 223 to the rear may be limited.
도 14는 또 다른 실시예에 따른 다단 구조의 피스톤이 형성된 체내 액체 투여기를 나타내는 사시도이다. 14 is a perspective view showing a body liquid dispenser having a piston having a multi-stage structure according to another embodiment.
도 14를 참조하면, 또 다른 실시예에 따른 다단 구조의 피스톤이 형성된 체내 액체 투여기(300)는 바디(310), 받침부(312), 및 피스톤(320)으로 구성되며, 바디(310)의 개방된 후단부로 피스톤(320)이 삽입되어 전방으로 이동 시 바디(310)의 내부에 수용된 액체(l)를 액체 분사구(311)를 통해 외부로 분사시킨다. 이때, 피스톤(320)은 전방으로 이동 후 장력이 발생하는 경우에 누름 부재(324, 325)와 피스톤 본체의 결합이 분리되어 피스톤 본체의 후방 이동이 제한됨으로써 재사용이 불가능하다. Referring to FIG. 14, the body liquid dispenser 300 having a piston having a multi-stage structure according to another embodiment includes a body 310, a support part 312, and a piston 320, and a body 310. The piston 320 is inserted into the open rear end of the liquid to eject the liquid (1) contained in the interior of the body 310 to the outside through the liquid injection port 311 when moving forward. In this case, when the piston 320 moves forward, tension is generated, the coupling between the pressing members 324 and 325 and the piston body is separated, so that the rear movement of the piston body is restricted, and thus reuse is impossible.
이러한 또 다른 실시예에 따른 다단 구조의 피스톤이 형성된 체내 액체 투여기(300)는 도 1 내지 도 9에서 설명한 일 실시예에 따른 다단 구조의 피스톤이 형성된 체내 액체 투여기(100)와 동일한 구성을 포함하고 있으므로 중복되는 내용은 생략한다. Intra-body liquid dispenser 300 formed with a piston having a multi-stage structure according to another embodiment has the same configuration as the intra-liquid liquid dispenser 100 is formed with a multi-stage piston according to an embodiment described in Figures 1 to 9 Since it is included, duplicate content is omitted.
또 다른 실시예에 따른 다단 구조의 피스톤이 형성된 체내 액체 투여기(300)의 피스톤(320)은 다단 구조로 이루어지며, 예컨대 제1 누름 부재(324) 및 제2 누름 부재(325)를 포함하는 2단 구조로 이루어질 수 있다. According to another embodiment, the piston 320 of the intra-liquid liquid injector 300 having the multistage structure is formed in a multistage structure, and includes, for example, a first pressing member 324 and a second pressing member 325. It can be made of a two-stage structure.
제2 누름 부재(325)의 후단부에는 사용자가 제1 누름 부재(324) 및 제2 누름 부재(325)를 쉽게 누르도록 표면이 넓게 형성된 누름대(327) 및 누름대(327)와 제2 누름 부재(325)의 결합을 위한 보조 부재(326)가 형성될 수 있다. At the rear end of the second pressing member 325, the pressing stand 327 and the pressing stand 327 and the second pressing member 324 and the second pressing member 325 have a wide surface to easily press the first pressing member 324 and the second pressing member 325. An auxiliary member 326 may be formed to engage the pressing member 325.
즉, 사용자가 누름대(327)를 가압함에 따라 제2 누름 부재(325)가 전방으로 이동되며, 이후 제1 누름 부재(324)가 전방으로 이동된다. 그리고 제1 누름 부재(324)와 결합된 피스톤 본체가 바디(310)의 내부에서 전방으로 이동됨으로써 바디(310) 내에 수용된 액체가 액체 분사구(311)를 통해 외부로 분사될 수 있다. That is, as the user presses the pusher 327, the second pressing member 325 moves forward, and then the first pressing member 324 moves forward. In addition, since the piston body coupled to the first pressing member 324 is moved forward in the interior of the body 310, the liquid contained in the body 310 may be injected to the outside through the liquid injection hole 311.
이때, 제1 누름 부재(324)의 홈부에 피스톤 본체의 후단부에 형성된 돌출부가 결합될 수 있다. 제1 누름 부재(324)에 형성된 홈부와 피스톤 본체에 형성된 돌출부가 결합되어 가압에 따라 전방으로 이동은 가능하되 후방 이동 시 홈부와 돌출부의 결합이 분리됨으로써, 장력이 발생하는 경우에도 피스톤 본체는 후방으로 이동하지 않고 제1 누름 부재(324) 및 제2 누름 부재(325)만 후방으로 이동될 수 있다. In this case, the protrusion formed at the rear end of the piston body may be coupled to the groove of the first pressing member 324. The groove formed on the first pressing member 324 and the protrusion formed on the piston body are coupled to each other, and the piston body is rearward even when tension is generated because the coupling between the groove and the protrusion is separated when moving backwards. Only the first pressing member 324 and the second pressing member 325 may be moved rearward without moving to.
도 15는 또 다른 실시예에 따른 다단 구조의 피스톤이 형성된 체내 액체 투여기의 받침부의 예를 설명하기 위한 도면이다. FIG. 15 is a view for explaining an example of a support part of a body liquid dispenser having a piston having a multi-stage structure according to another embodiment.
도 15를 참조하면, 받침부(312)는 내부 관통구가 형성되며 일측이 바디의 후단부에 연결되고, 타측이 피스톤과 연결된다. Referring to Figure 15, the support portion 312 is formed with an inner through hole, one side is connected to the rear end of the body, the other side is connected to the piston.
이러한 받침부(312)는 외주면에 소정 패턴이 형성되거나 외주면이 소정 형상으로 이루어져 사용자가 피스톤을 누르기 위해 받침부(312)를 파지할 때 사용자의 손이 미끄러지는 것을 방지할 수 있다.The support 312 may be formed in a predetermined pattern on the outer circumferential surface or the outer circumferential surface is formed in a predetermined shape to prevent the user's hand from slipping when the user grips the support 312 to press the piston.
받침부(312)는 원통 형상의 내부 관통구가 형성되고 외주면은 다각기둥 형상으로 이루어질 수 있다. The support part 312 may have a cylindrical inner through hole, and an outer circumferential surface thereof may have a polygonal pillar shape.
예를 들어, 도 15a에 도시된 바와 같이 받침부(312)는 원통 형상의 내부 관통구가 형성되고 외주면은 삼각기둥 형상으로 이루어질 수 있다. 다른 예로, 도 15b에 도시된 바와 같이 받침부(312)는 원통 형상의 내부 관통구가 형성되고 외주면은 팔각기둥 형상으로 이루어질 수 있다. 또 다른 예로, 도 15c에 도시된 바와 같이 받침부(312)는 원통 형상의 내부 관통구가 형성되고 외주면은 오각기둥 형상으로 이루어질 수 있으며, 도 15d에 도시된 바와 같이 받침부(312)는 원통 형상의 내부 관통구가 형성되고 외주면은 육각기둥 형상으로 이루어질 수 있다.For example, as shown in FIG. 15A, the supporting part 312 may have a cylindrical inner through hole, and an outer circumferential surface thereof may have a triangular prism shape. As another example, as shown in FIG. 15B, the support 312 may have a cylindrical inner through hole, and an outer circumferential surface thereof may have an octagonal pillar shape. As another example, as shown in FIG. 15C, the supporting portion 312 may have a cylindrical inner through hole, and an outer circumferential surface thereof may have a pentagonal pillar shape. As shown in FIG. 15D, the supporting portion 312 may have a cylindrical shape. The inner through hole is formed and the outer circumferential surface may be formed in a hexagonal column shape.
또한, 받침부(312)는 다각기둥 형상의 내부 관통구가 형성되고 외주면 또한 다각기둥 형상으로 이루어지는 것도 가능하다. In addition, the support portion 312 may be formed in the inner through-hole of the polygonal pillar shape, the outer peripheral surface may also be made of a polygonal pillar shape.
이러한 받침부(312)의 외주면은 바디의 둘레보다 큰 둘레를 가져 일측에 상부 케이스가 결합되고 타측에 하부 케이스가 결합될 수 있다.The outer circumferential surface of the base 312 may have a larger circumference than the circumference of the body so that the upper case is coupled to one side and the lower case is coupled to the other side.
이와 같이, 실시예들에 따르면 액체 주입을 위해 피스톤이 전방으로 이동 후 장력이 발생하는 경우 피스톤 본체와 누름 부재가 분리되어 누름 부재만 후방으로 이동됨으로써, 사용자가 임의로 피스톤 본체를 후방으로 이동시켜 재사용되는 것을 방지할 수 있다. As such, according to the embodiments, when the piston is moved forward to inject liquid and tension is generated, the piston body and the pressing member are separated, and only the pressing member is moved backward, so that the user may randomly move the piston body backward and reuse it. Can be prevented.
또한, 실시예들에 따르면 바디와 피스톤이 수용되고 내측에 바디의 액체 분사구에 삽입되는 마개가 형성된 케이스를 제공함으로써 별도의 케이스 없이 위생적으로 보관이 가능할 뿐만 아니라, 마개만 별도 형성되는 경우 바디로부터 마개가 쉽게 분리되어 액체가 유출되는 현상을 사전에 방지할 수 있다.In addition, according to the embodiments, the body and the piston is accommodated and provided with a case in which a stopper is inserted into the liquid injection hole of the body is not only hygienic storage possible without a separate case, but only stopper from the body when the stopper is formed separately Can be easily separated to prevent the liquid from leaking in advance.
