Description

미세 실린더펌프 및 이를 이용한 미세펌핑장치Fine cylinder pump and fine pumping device using same
본 발명은 미세 실린더펌프 및 이를 이용한 미세펌핑장치에 관한 것으로, 더욱 상세하게는 구조가 간단하고 크기가 작으며, 원격제어가 가능하고 안정적으로 액체의 주입이 가능한 미세 실린더펌프, 및 이러한 미세 실린더펌프를 손쉽게 장착 및 탈리하여 사용하는 미세펌핑장치에 관한 것이다.The present invention relates to a micro-cylinder pump and a micro-pumping apparatus using the same. More particularly, the micro-cylinder pump has a simple structure and a small size, and is capable of remote control and stable liquid injection, and such a micro-cylinder pump. The present invention relates to a micropumping device for easy installation and detachment.
약액용기 또는 혈액팩으로부터 약액 또는 혈액(이하에서는, '약액 또는 혈액'을 '약액'으로만 간략하여 기재한다.)을 일정하게 상당히 고정밀도로 제어하면서 환자에게 주입하기 위해서는 시린지 펌프 또는 인퓨전 펌프를 사용한다.A syringe pump or infusion pump is used to inject the drug solution or blood (hereinafter, briefly referred to as 'medicine solution or blood' only from the drug solution) from the drug container or blood pack into the patient with constant and highly precise control. do.
종래의 인퓨전 펌프(infusion pump)는 제조회사마다 다른 튜브의 탄성에 의하여 기계에 과부하가 걸려 고장률이 높고, 시린지 펌프(syringe pump)는 정밀성을 높이기 위해 기계가 복잡하여 크기가 크고 일정한 위치에 고정 설치된 상태에서만 사용이 가능하다. 시린지 펌프는 정밀성은 높으나 시린지를 이용하여 대용량은 사용하지 못하며 대용량 사용 시 반복해서 조작해야하는 불편함이 있다.Conventional infusion pumps are overloaded due to the elasticity of tubes that vary from manufacturer to manufacturer, resulting in high failure rates. Syringe pumps are complex, machine-size, and fixed at fixed locations for increased precision. Only available in the state. Syringe pump has high precision but can not use large capacity by using syringe, and there is inconvenience to operate repeatedly when using large capacity.
또한, 종래의 시린지 펌프 또는 인퓨전 펌프는 약액용기 또는 혈액팩의 설치위치, 즉 수두에 따라 배출되는 약액의 압력이 달라져서 거치대를 사용하여 일정한 높이에 약액용기 또는 혈액팩을 설치하여 사용하여야 하는 번거로움이 있다.In addition, the conventional syringe pump or infusion pump has a pressure to install the liquid container or blood pack, that is, the pressure of the chemical liquid discharged according to the chickenpox, so that the need to install the liquid container or blood pack at a certain height using a cradle There is this.
또, 시린지 펌프 또는 인퓨전 펌프의 정밀도가 미리 한정되어 있고, 정밀도가 높은 경우에는 약액의 공급량이 작아서, 요구되는 약액의 주입량의 정밀도에 따라 다른 시린지 펌프 또는 인퓨전 펌프를 사용하여야 하므로, 여러 대의 시린지 펌프 또는 인퓨전 펌프를 구비해야 하는 부담이 있다.In addition, since the precision of the syringe pump or the infusion pump is limited in advance, and the precision is high, the supply amount of the chemical liquid is small, so that different syringe pumps or infusion pumps should be used depending on the precision of the required injection amount of the chemical liquid. Or there is a burden of having an infusion pump.
그리고, 종래의 인퓨전 펌프는 기계의 단자가 튜브를 누르거나 쥐어짜는 페리스탈틱 방식이고 시린지 펌프는 시린지의 피스톤을 밀어 약물을 주입하는 방식으로 이들 모두 약액을 간접제어하는 방식이어서, 단자에 과부하가 걸리거나 복잡한 기계구조를 갖게 되어, 잦은 고장 등의 이유로 신뢰도가 낮거나 고가이므로, 수시로 간호인력이 투입되어야 하며, 원격제어가 어렵다.In addition, the conventional infusion pump is a peristaltic method in which the terminal of the machine presses or squeezes the tube, and the syringe pump injects drugs by pushing the piston of the syringe to indirectly control the chemicals, so that the terminal is overloaded. Because of the low or high reliability due to jammed or complicated mechanical structure, frequent failures, nursing personnel should be put in place from time to time, and remote control is difficult.
이에 본 출원인은 실린더펌프(한국특허 제10-0948632호)를 출원한 바 있다. 이 미세 실린더펌프는 고리형상의 실린더를 형성하며, 상기 실린더 내부를 회전하는 한쌍의 피스톤의 개별 및 동시회전운동에 의해 정밀한 유량제어가 가능하다. 다만, 상기 피스톤이 설치되는 푸싱부재에 부하가 커 피스톤이 밀려나는 단점이 있었다.The applicant has applied for a cylinder pump (Korea Patent No. 10-0948632). This fine cylinder pump forms an annular cylinder, and precise flow rate control is possible by the individual and simultaneous rotational movement of a pair of pistons rotating inside the cylinder. However, there is a disadvantage in that the piston is pushed out due to a large load on the pushing member in which the piston is installed.

그러므로, 본 발명의 핵심은 작동부에서 피스톤의 미세변위에 의해 정확하게 미세유량을 조절하는 것이다. Therefore, the core of the present invention is to precisely control the microflow rate by the microdisplacement of the piston in the operating portion.
특히, 본 발명에 따른 미세 실린더펌프는 구동장치에 착탈가능한 작동유니트이며, 상기 구동장치와 미세 실린더펌프가 미세펌핑장치를 이루게 된다. 따라서, 상기 구동장치는 영구적으로 사용할 수 있으며, 상기 작동유니트는 일회용으로 사용할 수 있다.In particular, the microcylinder pump according to the present invention is an operation unit detachable from the driving device, and the driving device and the fine cylinder pump form a fine pumping device. Thus, the drive device can be used permanently, and the operation unit can be used for single use.
도 1은 본 발명의 실시예에 따른 미세 실린더펌프(200)의 사시도이다. 상기 미세 실린더펌프(200)는 도 2에 도시된 바와 같이 구동장치(100)에 착탈가능하다. 상기 미세 실린더펌프(200)로 약액 또는 혈액 등의 액체, 분말이 혼합된 에멀젼, 또는 산소 등의 기체를 주입하는 경우에는, 상기 미세 실린더펌프(200) 만을 교체하여 사용할 수 있다.1 is a perspective view of a fine cylinder pump 200 according to an embodiment of the present invention. The fine cylinder pump 200 is detachable to the driving device 100 as shown in FIG. When injecting a liquid such as chemical liquid or blood, an emulsion in which powder is mixed, or a gas such as oxygen, into the fine cylinder pump 200, only the fine cylinder pump 200 may be replaced.
상기 구동장치(100)는 하우징(102)의 일측에 내부구동축(114)과 외부구동축(112)을 이중관형태로 하여 장착되며, 상기 구동장치(100)에는 내부구동축(114)과 외부구동축(112)이 배치되는 장착홈(108)이 형성될 수 있다. 상기 장착홈(108)에 상기 미세 실린더펌프(200)가 삽입되어 설치된다. 상기 내부구동축(114)과 상기 외부구동축(112)을 회전시키는 구성요소에 대해서는 설명을 생략한다(한국특허 제10-0948632호 참조). 또, 상기 내부구동축(114)과 상기 외부구동축(112)을 별개의 모터(미도시)로 작동시키는 것도 가능하다.The drive device 100 is mounted on one side of the housing 102 with an inner drive shaft 114 and an outer drive shaft 112 in a double tube form, and the drive device 100 has an inner drive shaft 114 and an outer drive shaft 112. ) May be formed with a mounting groove 108. The fine cylinder pump 200 is inserted into the mounting groove 108 is installed. Components for rotating the inner drive shaft 114 and the outer drive shaft 112 will be omitted (see Korean Patent No. 10-0948632). In addition, the inner drive shaft 114 and the outer drive shaft 112 may be operated by a separate motor (not shown).
이 때, 상기 장착홈(108)의 측벽에는 잠금홈(110)이 형성된다. 따라서, 상기 미세 실린더펌프(200)가 상기 잠금홈(110)에 삽입고정되면서 내부구동축(114)과 외부구동축(112)이 결합되고, 내부구동축(114)과 외부구동축(112)이 회전을 개시하면 상기 미세 실린더펌프(200) 내의 피스톤(230,256)이 회전하면서 상기 잠금홈(110)에 끼워 고정되어 인위적으로 탈리가 불가능한 잠금상태를 이루게 된다. 상기 내부구동축(1`14)과 상기 외부구동축(112)이 반대로 회전하면 해제상태를 이룰 수 있다. 이를 위해 상기 미세 실린더펌프(200)에는 상기 잠금홈(110)에 삽입되도록 장착돌기가 돌출형성된다. 상기 장착돌기는 하기(下記)하는 제1케이싱(202)과 제2케이싱(264)에 각각 형성되는 장착돌기반체(205,265)가 서로 결합되면서 이루어질 수 있다. 또는 제1케이싱(202)과 제2케이싱(264) 중 어느 일방에만 장착돌기가 형성되는 것도 가능하다. 특히, 도 2에서 상기 잠금홈(110)이 측벽이 아니라 상기 잠금홈(110)의 바닥면에 형성되고, 제1케이싱(202)에 형성되는 돌기가 장착되는 방식으로 형성되는 것도 가능하다.At this time, the locking groove 110 is formed on the side wall of the mounting groove (108). Therefore, the micro cylinder pump 200 is fixed to the locking groove 110, the inner drive shaft 114 and the outer drive shaft 112 is coupled, the inner drive shaft 114 and the outer drive shaft 112 starts to rotate. When the piston (230, 256) in the fine cylinder pump 200 is rotated to be fitted into the locking groove 110 to achieve a locked state that cannot be detached artificially. When the inner drive shaft 1`14 and the outer drive shaft 112 rotate in reverse, a release state may be achieved. To this end, the mounting cylinder is formed to protrude from the microcylinder pump 200 to be inserted into the locking groove 110. The mounting protrusion may be formed by coupling the mounting protrusions 205 and 265 formed in the first casing 202 and the second casing 264 to each other. Alternatively, the mounting protrusion may be formed only in any one of the first casing 202 and the second casing 264. In particular, in FIG. 2, the locking groove 110 may be formed on the bottom surface of the locking groove 110 instead of the side wall, and may be formed in a manner in which a protrusion formed in the first casing 202 is mounted.

The input unit 106 and the display window 104 may be located in various ways, such as the front or the top of the driving device for convenience.
상기 미세 실린더펌프(200)는 기본적으로 몸체를 이루는 제1케이싱(202) 및 제2케이싱(264)과, 상기 제1케이싱(202)에 삽입되는 제1회전부재(222)와, 상기 제2케이싱(264)에 삽입되는 제2회전부재(244)를 포함하여 이루어진다.The microcylinder pump 200 basically includes a first casing 202 and a second casing 264 constituting a body, a first rotating member 222 inserted into the first casing 202, and the second casing 202. And a second rotating member 244 inserted into the casing 264.
상기 제2케이싱(264)에는 약액이 상기 미세 실린더펌프(200)의 내부로 유입되는 유입관(213)과, 약액을 약액튜브 등에 공급시키는 유출관(215)이 형성된다(도 5 및 도 10 참조). 상기 유입관(213)과 상기 유출관(215)은 상기 제1케이싱(202)에 형성되거나, 상기 제1케이싱(202)과 상기 제2케이싱(264)에 절반씩 형성되는 것도 가능하다.The second casing 264 is formed with an inlet tube 213 through which the chemical liquid flows into the microcylinder pump 200, and an outlet tube 215 for supplying the chemical liquid to the chemical tube or the like (FIGS. 5 and 10). Reference). The inlet pipe 213 and the outlet pipe 215 may be formed in the first casing 202 or may be formed in half of the first casing 202 and the second casing 264.
또, 상기 제1케이싱(202)과 상기 제2케이싱(264)은 도 8에 도시된 바와 같이 서로 결합하면서 상기 제1회전부재(222)의 제1피스톤(230)과 상기 제2회전부재(244)의 제2피스톤(256)이 이동하는 고리형상의 실린더를 형성한다. 그리고, 상기 실린더에 상기 유입관(213)과 상기 유출관(215)가 연통되도록 유입구(266)과 유출구(268)이 형성된다. 따라서, 상기 유입구(266)와 상기 유출구(268)는 상기 제1케이싱(202)과 상기 제2케이싱(264) 중 어느 일방에 모두 형성되거나 각각 1개씩 형성되는 것도 가능하다.In addition, the first casing 202 and the second casing 264 are coupled to each other as shown in Figure 8 while the first piston 230 and the second rotating member (1) of the first rotating member 222 ( The second piston 256 of 244 forms an annular cylinder to which it moves. An inlet 266 and an outlet 268 are formed in the cylinder so that the inlet pipe 213 and the outlet pipe 215 communicate with each other. Therefore, the inlet port 266 and the outlet port 268 may be formed in either one of the first casing 202 and the second casing 264, or may be formed one by one.
상기 유입구(266)와 상기 유출구(268)의 사이각은 30°이며, 필요에 따라 조정이 가능하다. 이는 후술(後述)하는 피스톤(230,256)가 차지하는 중심각 30°와 일치하고, 상기 피스톤(230,256) 중 어느 하나가 상기 유입구(266)와 상기 유출구(268)의 사이에 위치할 때, 상기 유입구(266)와 상기 유출구(268)을 폐쇄하지 않도록 하기 위함이다. 따라서, 상기 유입구(266)와 상기 유출구(268)의 회전중심에 대한 중심각은 1개의 피스톤의 중심각(θ)의 1배 이상 2배 이하가 되도록 배치된다.The angle between the inlet 266 and the outlet 268 is 30 degrees, and can be adjusted as needed. This coincides with a central angle of 30 ° occupied by the pistons 230 and 256, which will be described later, and when one of the pistons 230 and 256 is located between the inlet port 266 and the outlet port 268, the inlet port 266 ) And the outlet 268 is not closed. Therefore, the center angle with respect to the center of rotation of the inlet port 266 and the outlet port 268 is disposed to be one or more times two times or less than the center angle θ of one piston.

The second casing 264 is engageable by coupling means such as bolts and nuts, or ultrasonic welding. Alternatively, direct fitting and groove fitting may be possible, which may use a known technique.
상기 제1회전부재(220)에는 한쌍의 제1피스톤고정구(232,234)가 설치되고, 상기 제1피스톤고정구(232,234) 사이에 제1피스톤(230)이 배치된다. 마찬가지로, 상기 제2회전부재(244)에는 한쌍의 제2피스톤고정구(258,260)가 설치되고, 상기 제2피스톤고정구(258,260) 사이에 제2피스톤(256)이 배치된다. 상기 제1피스톤(230) 및 상기 제2피스톤(256)의 단면적의 크기는 제1피스톤고정구(232,234) 및 제2피스톤고정구(258,260)의 단면적의 크기와 같거나 크다. 따라서, 상기 제1피스톤(230)과 상기 제2피스톤(256)는 전후에 배치되는 피스톤고정구(232,234,258,260)에 의해 지지되므로 더욱 안정적인 지지가 가능하며, 상기 피스톤고정구(232,234,258,260)는 하중이 분산되므로 상기 미세 실린더펌프(200)의 내구성이 향상되는 장점이 있다. 그리고, 상기 피스톤고정구(232,234,258,260)에 의해 상기 제1피스톤(230) 및 상기 제2피스톤(256)의 변형이 억제되므로, 상기 제1피스톤(230) 및 상기 제2피스톤(256) 사이의 공간이 일정하게 유지되어 유량제어의 정확도를 향상시킬 수 있다.A pair of first piston fixtures 232 and 234 are installed on the first rotating member 220, and a first piston 230 is disposed between the first piston fixtures 232 and 234. Similarly, a pair of second piston fixtures 258 and 260 are installed on the second rotating member 244, and a second piston 256 is disposed between the second piston fixtures 258 and 260. The size of the cross-sectional area of the first piston 230 and the second piston 256 is equal to or larger than the size of the cross-sectional areas of the first piston fixtures 232 and 234 and the second piston fixtures 258 and 260. Therefore, since the first piston 230 and the second piston 256 are supported by the piston fasteners 232, 234, 258 and 260 disposed before and after, the piston pistons 232, 234, 258 and 260 can be more stably supported. There is an advantage that the durability of the fine cylinder pump 200 is improved. In addition, since deformation of the first piston 230 and the second piston 256 is suppressed by the piston fixtures 232, 234, 258 and 260, the space between the first piston 230 and the second piston 256 is reduced. It can be kept constant to improve the accuracy of flow control.

상기 미세 실린더펌프(200)는 기본적으로 상술한 바와 같이 구성되며, 이하 그 조립된 상태 및 작동방법에 대해 설명한다.The fine cylinder pump 200 is basically configured as described above, it will be described below the assembled state and operation method.
도 8은 상기 미세 실린더펌프(200)의 상기 제1회전부재(222)와 상기 제2회전부재(244)를 조립 후, 상기 미세 실린더펌프(200)의 작동순서를 개략적으로 설명한 도면이다.8 is a view schematically illustrating an operation procedure of the microcylinder pump 200 after assembling the first and second rotation members 222 and 244 of the microcylinder pump 200.
도 3 및 도 4에 도시된 바와 같이 제2케이싱(264)을 기준으로 하여 설명하고, 유입구(266) 및 유출구(268)은 제2케이싱(202)에 설치되었지만, 이해의 편의를 위해 제1케이싱(202)에 연통되는 것으로 도시한다. 또, 유입구(266) 및 유출구(268)의 위치는 상기 피스톤(230,256)가 반시계방향으로 회전할 경우이며, 만일 상기 피스톤(230,256)의 회전방향이 시계방향이라면 도면부호 266이 유출관이 되고 도면부호 268가 유입관이 된다.3 and 4, the inlet 266 and the outlet 268 are installed in the second casing 202, but the first casing 202 is provided for convenience of understanding. It is shown as being in communication with the casing 202. In addition, the positions of the inlets 266 and the outlets 268 are when the pistons 230 and 256 rotate counterclockwise, and if the direction of rotation of the pistons 230 and 256 is clockwise, reference numeral 266 becomes the outlet tube. Reference numeral 268 denotes an inlet pipe.
조립되는 제품은 밀봉상태로, 도 8a에 표시된 피스톤(230,256)이 반시계방향으로 좀 더 회전하여, 상기 피스톤(230,256)가 유입구(266) 및 유출구(268)를 폐쇄한 상태이다.The assembled product is in a sealed state, in which the pistons 230 and 256 shown in FIG. 8A are further rotated counterclockwise, so that the pistons 230 and 256 close the inlet 266 and the outlet 268.
그리고, 동작개시상태는 도 8a에 도시된 바와 같이, 어느 하나의 피스톤(256)가 상기 유입구(266) 및 상기 유출구(268)의 사이에 위치하고, 다른 피스톤(230)가 유입관(276)을 폐쇄한 상태이다. 밀봉상태에서 동작개시상태는 상기 구동장치(100)의 동작을 통해 실현한다.8A, one piston 256 is positioned between the inlet 266 and the outlet 268, and the other piston 230 opens the inlet 276. It is closed. The operation start state in the sealed state is realized through the operation of the drive device (100).
다음으로, 상기 피스톤(230)가 도 8b와 같이 반시계방향으로 회전하기 시작하면, 상기 실린더내에 부압이 발생되면서 상기 유입구(266)을 통해 약액이 상기 실린더 내로 유입된다. 그리고, 반시계방향의 회전을 계속 하게 되면 도 8c에 도시된 바와 같이 상기 피스톤(230)는 상기 유출관(216) 및 상기 유입관(214)의 사이에 위치된 피스톤(256)에 맞닿게 된다. 즉, 상기 피스톤(230)는 300°를 회전하게 된다. 이 상태에서는 상기 피스톤(230)가 상기 유출구(268)을 폐쇄한 상태이다.Next, when the piston 230 starts to rotate in the counterclockwise direction as shown in FIG. 8B, negative pressure is generated in the cylinder, and the chemical liquid is introduced into the cylinder through the inlet port 266. And, if the rotation continues in the counterclockwise direction as shown in Figure 8c the piston 230 is in contact with the piston 256 located between the outlet pipe 216 and the inlet pipe 214. . That is, the piston 230 is rotated 300 °. In this state, the piston 230 closes the outlet 268.
그리고, 선행하는 피스톤(256)과 후행하는 피스톤(230)가 동시에 30°만큼 반시계방향으로 회전한다. 따라서, 도 8d에 도시되는 바와 같이 후행하는 피스톤(230)가 유입구(266) 및 유출구(268)의 사이에 위치하게 된다. 이 상태에서 도 8e 및 도 8f와 같이 상기 피스톤(256)가 반시계방향으로 회전하면서 상기 피스톤(256)보다 회전방향으로(반시계방향으로) 앞쪽에 위치한 상기 실린더 내의 약액이 상기 유출구(268)을 통해 배출되게 된다. 동시에, 상기 유입구(266)을 통해서 약액이 상기 피스톤(256)의 후측으로 유입되어 상기 실린더 내부를 채우게 된다. 다시 말해, 회전하는 피스톤(256)에 의해 약액의 배출과 유입이 동시에 일어나게 된다.And the preceding piston 256 and the following piston 230 rotate counterclockwise by 30 degrees simultaneously. Thus, as shown in FIG. 8D, the trailing piston 230 is positioned between the inlet 266 and the outlet 268. In this state, as the piston 256 rotates counterclockwise as shown in FIGS. 8E and 8F, the chemical liquid in the cylinder located in the rotational direction (counterclockwise) ahead of the piston 256 is discharged from the outlet 268. It will be discharged through. At the same time, the chemical liquid flows into the rear side of the piston 256 through the inlet port 266 to fill the inside of the cylinder. In other words, the discharge and inflow of the chemical liquid occurs at the same time by the rotating piston (256).
그리고, 상기 피스톤(256)가 반시계방향의 회전을 계속하게 되면 도 8g에 도시된 바와 같이 상기 피스톤(256)는 유입구(266) 및 유출구(268)의 사이에 위치된 피스톤(230)에 맞닿게 된다. 즉, 상기 피스톤(256)는 300°를 회전하게 된다. 이 상태에서는 상기 피스톤(256)가 상기 유출구(268)를 폐쇄한 상태이다.When the piston 256 continues to rotate in the counterclockwise direction, as shown in FIG. 8G, the piston 256 fits the piston 230 positioned between the inlet 266 and the outlet 268. Is reached. That is, the piston 256 is to rotate 300 °. In this state, the piston 256 closes the outlet 268.
또, 선행하는 피스톤(230)과 후행하는 피스톤(256)가 동시에 30°만큼 반시계방향으로 회전하여, 다시 도 8h(도 8a와 동일)와 같은 상태로 복귀한다.In addition, the preceding piston 230 and the following piston 256 simultaneously rotate counterclockwise by 30 °, and return to the same state as in FIG. 8H (same as FIG. 8A).
상술한 바와 같이, 상기 피스톤(230,256)가 각각 1회전씩 하게 되면, 다시 도 8a 내지 도 8g에 도시된 동작을 반복적으로 수행하게 된다. 따라서, 상기와 같은 과정이 반복하면서 상기 미세 실린더펌프(200)는 약액의 공급을 연속적으로 수행할 수 있으며, 상기 피스톤(230,256)의 회전속도를 제어하는 것에 의해 약액 공급량의 미세조절이 가능하게 된다.As described above, when the pistons 230 and 256 are rotated by one rotation, respectively, the operations shown in FIGS. 8A to 8G are repeatedly performed. Therefore, the above-described process is repeated, the fine cylinder pump 200 can continuously perform the supply of the chemical liquid, by controlling the rotational speed of the piston (230, 256) it is possible to fine-tune the chemical liquid supply amount .
도 9는 상기 미세 실린더펌프(200)의 적용예를 도시한다. 즉, 유입포트(214)에 다방변(40)을 설치하는 것에 의해 2종 이상의 액체를 선택적으로 공급하거나 다방변(40)의 노브(42)의 조작을 통해 어느 하나의 튜브(16)에 시린지를 연결시키면 시린지 내의 약, 액을 빨아 들여 공급하는 것이 가능하다, 즉 시린지 펌프의 역할이 가능하여 실린더 펌프는 인퓨젼펌프의 역할과 시린지펌프의 역할이 하나로 가능하다. 따라서, 상기 다방변(40)의 일측에는 1개의 튜브(14)가 연결되고, 타측에는 2개의 튜브(16,18)가 연결되었다. 마찬가지로, 유출포트(216)에 다방변을 설치하여 배출되는 방향을 2 이상으로 선택하는 것도 가능하다.9 shows an application example of the fine cylinder pump 200. That is, by providing the multi-side 40 in the inlet port 214, two or more liquids are selectively supplied or the syringe 16 to any one tube 16 through the operation of the knob 42 of the multi-side 40 It is possible to supply the medicine and the liquid in the syringe by connecting it, that is, the role of the syringe pump is possible, the cylinder pump is one of the role of the infusion pump and the role of the syringe pump. Therefore, one tube 14 is connected to one side of the multi-side 40, and two tubes 16 and 18 are connected to the other side. Similarly, it is also possible to select two or more directions in which the discharge port 216 is provided with multiple directions.
도 10과 도 11은 상기 미세 실린더펌프(200)의 오작동을 방지하고 종료상태를 감지하기 위하여 기포감지기능과 폐색감지기능을 가지는 센싱부를 설치하는 모습을 도시한다.10 and 11 illustrate a state in which a sensing unit having a bubble detection function and a blockage detection function is installed to prevent a malfunction of the microcylinder pump 200 and detect an end state.
상기 센서부는 상기 유입관(213) 및 상기 유출관(215)에 모두 설치될 수 있다. 먼저, 상기 센서부는 상기 유입관(213) 및 상기 유출관(215)에 연결되는 연결포트(302,304)와, 상기 연결포트(302,304)에 연결되는 센서하우징(314,320)과, 상기 센서하우징(314,320) 내부에 삽입되는 센싱튜브(306,308)와, 상기 센서하우징(314,320)에 형성되는 센서설치구(316,318,322,324)에 설치되는 센서(310,312,326,328)를 포함한다.The sensor unit may be installed in both the inlet pipe 213 and the outlet pipe 215. First, the sensor unit is connected to the inlet pipe 213 and the outlet pipe 215, the connection port (302, 304), the sensor housing (314, 320) connected to the connection port (302, 304), and the sensor housing (314, 320) The sensing tubes 306 and 308 inserted therein, and the sensors 310, 312, 326 and 328 installed in the sensor installation holes 316, 318, 322 and 324 formed in the sensor housings 314 and 320 are included.
상기 센서(310,312,326,328)는 로드셀(326,328)과 초음파센서(310,312)로 이루어진다. 상기 로드셀(326,328)은 상기 미세 실린더펌프(200) 뿐 아니라 연결되는 어느 위치에서도 관이 접히거나 폐색되면 압력이 상승하기 때문에서 상기 센싱튜브(306,308)는 팽창하게 되며, 이 결과 상기 센서설치구(318,324)을 통해 부풀게 된다. 이 때, 상기 로드셀(326,328)에 의해 팽창압을 측정하여 기준범위를 넘어서거나 부족하면 튜브의 폐쇄여부를 감지하여 상기 구동장치(100)를 정지시키거나 알람을 울려 사용자에게 문제가 발생함을 인식시켜 후조치를 하도록 하는 것에 의해 의료사고를 막을 수 있다. 또, 상기 초음파센서(310,312)는 상기 센싱튜브(306,308) 내의 버블을 감지하는 것으로, 버블이 발생하여 이동할 때 초음파진동을 주어 되돌아 오는 진동을 측정하여 액체 내에 버블이 혼입되어 있음을 알 수 있게 된다. 이 경우에도 상기 구동장치(100)를 정지시키거나 알람을 울려서, 버블유입에 따라 발생될 수 있는 문제점을 방지할 수 있다.The sensors 310, 312, 326, and 328 are composed of load cells 326, 328 and ultrasonic sensors 310, 312. The load cells 326 and 328 expand in pressure because the pressure rises when the pipe is folded or closed at any position where the micro cylinder pump 200 is connected, as well as the micro cylinder pump 200. As a result, the sensor installation holes ( 318,324). At this time, by measuring the inflation pressure by the load cells (326,328) if it exceeds or falls short of the reference range to detect the closing of the tube to stop the driving device 100 or alarm to recognize that a problem occurs to the user It is possible to prevent medical accidents by making them follow up. In addition, the ultrasonic sensors 310 and 312 detect the bubbles in the sensing tubes 306 and 308. When the bubbles are generated and moved, the ultrasonic sensors 310 and 312 measure ultrasonic vibrations, and thus, the bubbles are mixed in the liquid. . Even in this case, the driving device 100 may be stopped or an alarm may be prevented, which may be caused by a bubble inflow.
상기 센서하우징(314,320)에는 장착포트(330,332)가 연결되어, 액체가 유입 및 공급되는 별도의 튜브(10,12)와 연결될 수 있다. 상기 장착포트(332)에는 커플러(334)가 설치되어 나사선을 가지는 기구와 체결이 가능하다.Mounting ports 330 and 332 may be connected to the sensor housings 314 and 320, and may be connected to separate tubes 10 and 12 into which liquid is introduced and supplied. Coupler 334 is installed in the mounting port 332 can be fastened to the mechanism having a screw line.
