Description

조립이 용이하고 주입된 약물이 모두 배출되는 약액 공급장치Easy to assemble and dispensing all injected drugs
본 발명은 약액을 공급하여 주는 약액 공급장치에 관한 것으로, 좀더 자세히 설명하면 조립이 용이하여 생산성을 향상시켜 줄 뿐만 아니라, 특히 팽창되어 있던 탄성체가 수축하면서 상기 탄성체가 내장하고 있는 약액을 모두 배출토록 한 원형의 약액 공급장치에 관한 것이다.The present invention relates to a chemical liquid supplying device for supplying a chemical liquid, and when described in more detail, it is easy to assemble to improve productivity, and in particular, to expand all of the chemical liquid contained in the elastic body as the expanded elastic body contracts. It relates to a circular chemical liquid supply device.
일반적으로 약물을 주입할 때에는 링거대에 약물팩을 걸고 대기압에 의해 환자에게 약액을 공급하여 준다. 그러나 이러한 방법은 움직임에 제약이 따르고 특히 약물이 용적량의 변화와 위치 변화에 따라 압력이 줄어들면서 낙하하는 약물의 주입속도가 변화하면서 중간에 다시 클램프를 조절하여 떨어지는 약물의 양을 재조정해 주어야만 하였던 것이다.In general, when injecting drugs, the drug pack is put on the ringer and the medicine is supplied to the patient by atmospheric pressure. However, this method was constrained by movement, and the drug had to be re-adjusted by dropping the clamp in the middle as the injection rate of the falling drug changed as the pressure decreased as the volume change and position changed. .
그러나 환자가 수술중에 있거나 혹은 중한 상태에 있을 경우에는 생명을 유지시켜 주기 위하여 혹은 치료를 의하여 의사의 지도하에 정밀한 약액의 주입이 요구됨으로, 불규칙하게 약액이 환자에게 주입되게 되면 생명에 심각한 문제를 초래할 수도 있다.However, if the patient is in surgery or in a severe state, it is necessary to inject the medicine precisely under the guidance of the doctor to maintain life or to treat it. Therefore, irregular injection of the medicine into the patient may cause serious problems for life. It may be.
따라서 이러한 문제점을 해결하기 위하여 별도로 정밀하게 약액을 주입할 수 있는 약액 공급장치와 컨트롤러가 개발되게 된 것이다.(국내등록특허:10-0519247)Therefore, in order to solve this problem, a chemical liquid supply device and a controller capable of injecting chemical liquids separately and precisely have been developed. (Domestic Patent No. 10-0519247)

상기 몸체(31)의 좌우 결합단면에 각각 한 쌍의 고정체(33)를 끼워 결합시켜줌으로써, 탄성체(32)가 만곡된 외주면을 가진 몸체를 감싼 상태로 가압체(30)를 조립하여 주는 것이다.By fitting a pair of fixing bodies 33 to the left and right coupling end surfaces of the body 31, the pressing body 30 is assembled in a state in which the elastic body 32 wraps the body having the curved outer circumferential surface. .
참고로, 상기 몸체(31)의 결합단면에는, 호스의 결합관(34)과 결합편이 끼워지는 고정홈(31h) 및 주입홈(31d)이 형성되어 있고, 이를 중심으로 일정한 간격을 유지하고 있는 원형의 걸림턱(31f)과 결합홈(31g)을 형성하여, 상기 탄성체(32)가 몸체(31)를 수용했을 때 양 측단에 형성되어 있는 돌출테(32a)가 몸체의 걸림턱(31f) 안쪽으로 내입되게 조립하고,For reference, a coupling groove 34h and an injection groove 31d into which the coupling pipe 34 and the coupling piece of the hose are fitted are formed at the coupling end surface of the body 31, and maintain a constant distance therefrom. A circular locking jaw 31f and a coupling groove 31g are formed so that when the elastic body 32 receives the body 31, the protruding frames 32a formed at both side ends thereof have the locking jaw 31f of the body. To assemble inward,
이때, 고정체(33)는 상기 걸림턱(31f)과 결합홈(31g)에 대응하는 내측테(33b) 및 외측테(33a)를 형성하여,At this time, the fixing body 33 forms the inner frame 33b and the outer frame 33a corresponding to the engaging jaw 31f and the coupling groove 31g,
상기 고정체(33)가 몸체의 결합단면(33b.33c)에 끼워져 설치되었을 때, 걸림턱(31f) 안쪽으로 내입되어 있는 돌출테(32a)가 고정체(33)와 몸체(31)에 의해 물려지면서 고정되어 있도록 한다. 그리고 이때 내측에 형성되어 있는 결합홈(31g)과 내측테(33b)에는 돌기와 홈이 형성되어 있어 초음파 접합하여 고정체와 몸체를 단단히 고정하는 것이다.When the fixing body 33 is fitted to the coupling end face 33b.33c of the body, the protruding frame 32a, which is inwardly inserted into the locking jaw 31f, is formed by the fixing body 33 and the body 31. Make sure it is bitten and fixed. At this time, the coupling groove 31g and the inner frame 33b formed at the inner side are formed with protrusions and grooves, thereby ultrasonically bonding to fix the fixed body and the body firmly.
참고로, 이때 본 발명은 다양한 방법으로 몸체에 고정체(33)를 고정하여 줄 수 있고, 도 5의 확대도에 도시된 바와 같이, 탄성체(32)가 늘어나 그 두께가 얇아질지라도 걸림턱(31f) 안쪽으로 내입되어 있는 탄성체(32)의 돌출테(32a)가 밖으로 빠져나가지 않도록 고정하여 줄 수도 있는 것이다.For reference, in this case, the present invention may fix the fixing body 33 to the body in various ways, and as shown in the enlarged view of FIG. 5, even when the elastic body 32 increases and the thickness thereof becomes thin, the locking jaw ( 31f) The protruding frame 32a of the elastic body 32, which is inwardly inserted, may be fixed so as not to escape.
즉, 몸체(31)의 걸림턱(31f) 안쪽으로 내입홈(31i)을 형성하고, 대응하는 고정체(33)에도 같은 위치에 대응하는 내입홈(33c)을 하나 더 형성한 상태에서,That is, in the state in which the indentation groove 31i is formed in the engaging jaw 31f of the body 31, and the indentation groove 33c corresponding to the same position is also formed in the corresponding fixing body 33,
상기 탄성체(32)가 몸체(31)를 수용하여 돌출테(32a)가 결합단면의 걸림턱(33f) 안쪽에 내입되게 될 때 걸림턱(31f)과 돌출테(32a) 사이에 이격된 공간(32b)을 형성한 채로 내입되어 지도록 하여, The space spaced between the engaging jaw 31f and the protruding frame 32a when the elastic body 32 receives the body 31 and the protruding frame 32a is to be inserted into the engaging jaw 33f of the coupling end surface ( 32b) to be incorporated,
고정체(33) 끼움시 외측테(33a)가 걸림턱(31f) 안쪽에 내입되면서 걸림턱(31f)과 돌출테(32a) 사이의 이격된 공간(32b)을 매워주면서 탄성체의 측단에 형성되어 있는 돌출테(32a)가 몸체의 내입홈(31i)과 고정체의 내입홈(32c) 안쪽으로 밀려들어가 매워진 상태로 결합하여 줌으로써, When the fixing body 33 is fitted, the outer frame 33a is formed inside the locking jaw 31f and fills the space 32b between the locking jaw 31f and the protruding frame 32a while being formed at the side end of the elastic body. Protruding frame (32a) is pushed into the inner groove (31i) of the body and the inner groove (32c) of the fixing body to combine in a state filled with,
탄성체(32)가 주입된 약액에 의해 부피가 늘어나면서 그 두께가 얇아질지라도 돌출테(32a)가 걸림턱(31f) 안쪽의 내입홈(31i,32c)을 매운상태로 고정체에 의해 물려져 단단히 고정되어 있게 되는 것이다.Although the elastic body 32 is increased in volume by the injected chemical liquid, the thickness thereof becomes thin, but the protruding frame 32a is bitten by the fixing body with the inner grooves 31i and 32c inside the latching jaw 31f being spicy. It will be firmly fixed.
참고로, 도 6은 이러한 가압체(30)에 약액을 주입하였을 때와 배출될 때의 모습을 보여주는 것으로, 도시된 바와 같이, 본 발명은 압력을 가하여 몸체 안쪽으로 약액을 주입하게 되면, 약물이 주입홈(31d)과 유로(31e)를 따라 몸체 안쪽으로 들어와 외주면(31a) 밖으로 밀려나오게 된다.For reference, FIG. 6 shows the state when the liquid is injected into the pressurized body 30 and when it is discharged, as shown in the present invention, when the liquid is injected into the body by applying pressure, the drug is It enters into the body along the injection groove 31d and the flow path 31e, and is pushed out of the outer circumferential surface 31a.
이때, 외주면(31a)을 감싸고 있던 탄성체(32)는 밀려나온 약액에 의해 팽창하게 되면서, 밀착되어 있던 탄성체(32)와 외주면(31a) 사이의 공간에 주입된 약물을 수용할 수 있게 되는 것이다.At this time, the elastic body 32 surrounding the outer circumferential surface 31a is expanded by the chemical liquid pushed out, and thus the drug injected into the space between the elastic body 32 and the outer circumferential surface 31a which is in close contact with each other can be accommodated.
참고로 이때 하부케이스(20)에 직접 주입구(미도시)와 역류방지체크밸브(미도시)를 형성하고, 상기 주입구와 가압체(30)를 연결하여, 약액을 직접 가압체(30) 쪽으로 주입할 수 있도록 할 수 있으나, For reference, at this time, an injection hole (not shown) and a non-return check valve (not shown) are directly formed in the lower case 20, and the injection hole and the pressurizer 30 are connected to directly inject the chemical liquid toward the pressurizer 30. You can do it, but
도 7에 도시된 바와 같이 실시 예에 따라서는 상기 가압체(30)와 연결되는 호스(3)에 별도로 역류방지체크밸브와 주입관(4)를 형성하고 상기 주입관에 주사기(5)를 끼워 내장된 양물을 가압체(30)쪽으로 주입할 수도 있다.As shown in FIG. 7, the non-return check valve and the injection tube 4 are separately formed in the hose 3 connected to the pressurizer 30, and the syringe 5 is inserted into the injection tube. The embedded good may be injected into the press body 30.
참고로, 이때 본 발명에서는 고정 플레이트(50)를 더 포함하여 이루어져, 주사기(5)에 담겨져 있는 약액을 가압체(30)쪽으로 안전하게 주입하여 수용토록 할 수도 있는 것이다.For reference, in this case, the present invention may further include a fixing plate 50, so that the chemical solution contained in the syringe 5 may be safely injected into the pressurized body 30 so as to be accommodated.
즉, 주사기의 피스톤을 눌러줘서 약액을 가압체(30)쪽으로 주입할 경우, 탄성체(32)를 팽창시키기 위해서는 상당량의 힘으로 피스톤을 눌러줘야지만 함으로, 작은 크기의 주입관(4)과 호스(3)의 움직임을 고정하여 주기 위한 고정 플레이트(50)가 별도로 요구되게 되는 것이다.That is, when pressing the piston of the syringe to inject the chemical liquid into the pressurized body 30, in order to expand the elastic body 32 to press the piston with a considerable amount of force, the small size of the injection tube 4 and the hose (3) Fixing plate 50 for fixing the movement of the) will be required separately.
따라서 본 발명의 실시 예에 따른 고정 플레이트(50)는 평평한 플레이트(51)를 형성하고, 상기 플레이트의 상단 일부를 돌출시켜 장착부(52)를 형성한 상태에서, Therefore, the fixing plate 50 according to the embodiment of the present invention forms a flat plate 51, and in a state in which the mounting portion 52 is formed by protruding a portion of the upper end of the plate,
상기 장착부(52)의 일측과 타측을 가로지르는 내입골(53)과 장착홈(54)을 형성하여, By forming the inner bone 53 and the mounting groove 54 across one side and the other side of the mounting portion 52,
호스 및 주입관이 내입골(53)과 장착홈(54)에 끼워져 고정되어 있을 때 주입관의 마개를 오픈하고 주사기를 끼워 피스톤 동작시 내장된 약액을 가압체(30) 쪽으로 안전하면서 용이하게 약액을 주입할 수 있도록 한 것이다.When the hose and the injection tube are inserted into the inlet bone 53 and the mounting groove 54 and are fixed, the stopper of the injection tube is opened and the syringe is inserted into the chemical solution safely and easily toward the pressurizer 30 during the piston operation. It is to be able to inject.
참고로 이때 플레이트(51) 하단에는 마찰력을 최대화하여 미끄러지지 않도록 하는 고무 또는 실리콘 재질의 고정패드(55)를 더 형성할 수도 있는 것이다.For reference, at this time, the bottom of the plate 51 may further form a fixing pad 55 made of rubber or silicon to maximize the friction force so as not to slip.
그리고 이렇게 주사기에 담겨져 있는 약액을 주입하여 탄성체가 약액의 수용을 완료하게 되면, When the elastic body completes the acceptance of the chemical liquid by injecting the chemical liquid contained in the syringe like this,
몸체(31)를 감싸고 있는 탄성체(32)가 수축하려고 하고, 이때 호스와 연결되어 있는 컨트롤러(미도시)나 밸브(미도시)가 클로즈(Close)되어 있으면 상기 탄성체(32)가 계속 팽창되어 있는 상태를 유지하고 있게 된다.The elastic body 32 surrounding the body 31 attempts to contract. At this time, if the controller (not shown) or the valve (not shown) connected to the hose is closed, the elastic body 32 is continuously inflated. The state is maintained.
그러나 컨트롤러(미도시)나 밸브를 오픈(Open)하여 주게 되면, 상기 탄성체(32)가 수축하면서 안쪽에 내장되어 있는 약액을 외주면(31a)쪽으로 밀어내게 되고, 이때 밀려나온 액액은 외주면 안쪽의 유로(31e)와 주입홈(31d) 따라 외부(환자에게)로 배출되게 되는 것이다.However, when the controller (not shown) or the valve is opened, the elastic body 32 contracts and pushes the chemical liquid contained therein toward the outer circumferential surface 31a. At this time, the liquid liquid pushed out is a flow path inside the outer circumferential surface. It is to be discharged to the outside (to the patient) along the 31e and the injection groove 31d.
특히 이때 탄성체(32)는 만곡된 외주면(31a) 전체를 감싸고 있고, 만곡된 외주면(31a) 전체에 압력을 가하여 탄성체와 외주면 사이에 수용되어 있는 약액 전체를 유로(31e) 밖으로 밀어내게 되어 최대한 많은 량의 약액을 모두 배출할 수 있게 되는 것이다.In particular, the elastic body 32 surrounds the entire curved outer circumferential surface 31a, and applies pressure to the entire curved outer circumferential surface 31a to push out the entire chemical solution contained between the elastic body and the outer circumferential surface out of the flow path 31e. It will be able to discharge all the amount of chemicals.
더욱이 이렇게 모듈화되어 있는 가압체(30)를 하부케이스(20)의 내적공간(21) 안쪽에 끼워 결합시켜 주기만 하면 됨으로, 용이하게 조립할 수 있고, 이에 따른 조립시간이 단축되게 되어 생산성이 향상되는 것이다.Furthermore, the modular body of the pressurizer 30 may be simply inserted into the inner space 21 of the lower case 20 so as to be combined, and thus easily assembled, thereby reducing assembly time, thereby improving productivity. .
