Description

수액 정량 공급장치Quantity Feeding Device
본 발명은 혈관 주사제나 영양제와 같은 수액을 체내에 투여하기 위한 수액공급장치에 관한 것으로, 보다 상세하게는 수액의 양이나 수액의 위치변화에 상관없이 항상 일정한 양의 수액을 자동으로 공급할 수 있는 수액 정량 공급장치에 관한 것이다.The present invention relates to a fluid supply device for administering a fluid such as a blood vessel injector or a nutrient into the body, and more particularly to a fluid supply device for automatically supplying a constant amount of fluid irrespective of the amount of the fluid or the position of the fluid. To a constant amount feeding device.
일반적으로 수액이나 주사액을 지속적으로 체내에 투여하기 위해서는 수액이 담긴 병 또는 봉지형상의 수액용기와 수액용기에 연결된 수액호스와 수액호스에 결합된 주사바늘과 수액호스 중간에 수액호스를 압박하여 공급되는 수액의 양을 조절해 주는 수액조절기구가 구비된 수액공급장치가 요구된다.Generally, in order to continuously inject a fluid or an injection into the body, it is necessary to pressurize the fluid hose between the injection needle and the fluid hose which are connected to the fluid-containing hose and the fluid hose connected to the fluid- There is a need for a fluid supply device provided with a fluid control mechanism for controlling the amount of fluid.
그러나, 이러한 종래의 수액공급장치는 수액용기에 저장된 수액이 위치에너지와 혈관내의 압력에 따른 관계에 의해 체내에 투입되도록 하는 원리가 적용되고 있기 때문에 수액용기의 거치위치가 높거나 환자가 누워있을 때에는 수액공급이 원활하게 이루어지지만 수액용기의 거치위치가 낮거나 환자가 서있을 때에는 수액공급이 원활하게 이루어지지 않게 된다. 또한, 수액용기 내에 저장된 수액양이 많을 경우에는 수액용기 내부의 압력이 크기 때문에 수액공급이 원활하게 이루어지지만 환자에게 투여되는 양이 증가하면서 수액용기 내의 수액양이 점차로 적어질수록 수용용기 내부의 압력도 동반 하락하면서 수액공급이 원활하게 이루어지지 않게 된다. 심할 경우, 수액의 공급압이 혈압보다 낮게 되면 수액의 투입이 이루어지지 않을 뿐만 아니라 혈액이 역류되는 사고가 발생할 수도 있다.However, such a conventional liquid supply device is applied to the principle that the liquid stored in the liquid container is injected into the body due to the relationship between the potential energy and the pressure in the blood vessel. Therefore, when the liquid container is placed at a high position or the patient is lying Although the supply of the fluid is smooth, the supply of fluid is not smooth when the position of the liquid container is low or when the patient is standing. In addition, when the amount of the liquid stored in the liquid container is large, the liquid is supplied smoothly because of the pressure inside the liquid container. However, as the amount of the liquid administered to the patient increases and the amount of liquid in the liquid container gradually decreases, The supply of fluid is not smooth. In severe cases, when the supply pressure of the fluid is lower than the blood pressure, not only the fluid is injected but also blood may be backflowed.
따라서, 종래의 수액공급장치는 환자의 행동에 큰 제약이 뒤따르게 되고 지속적으로 변화하는 수액공급상태를 수시로 점검하여야 하며, 주기적으로 조액조절기구를 조작하거나 수액용기를 더 높은 곳으로 이동시켜 수액공급상태를 원활하게 유지시켜 주어야 하는 등 보호자의 세심한 주의와 배려가 요구된다.Therefore, the conventional liquid supply device has a great restriction on the patient's behavior, and it is necessary to constantly check the constantly changing liquid supply condition, periodically operate the liquid adjustment mechanism, or move the liquid container to a higher position, Careful attention and care of the caregiver are required such as keeping the condition smooth.

도 1 내지 도 5에 도시된 바와 같이, 본 발명은 본체(110)와 상기 본체(110)에 착탈가능하게 결합되는 키트(120)로 크게 구성되며, 수액용기(A)와 주사바늘(B)을 연결하는 수액호스(C)의 일측에 설치되어 수액호스(C)가 형성하고 있는 유로의 일부를 이룬다.1 to 5, the present invention is largely composed of a main body 110 and a kit 120 detachably coupled to the main body 110. The main body 110 includes a liquid receiver A and an injection needle B, And a part of the flow path formed by the fluid hose C is formed.
상기 본체(110)는 구동모터(111)와 상기 구동모터(111)에 전원을 공급해 주는 전원공급부(112)를 구비한다. 상기 전원공급부(112)는 외부로부터 전원을 공급받아 구동모터(111)로 구동전원을 제공해 주도록 구성될 수도 있지만, 본 발명이 수액호스(C)의 일측에 설치되는 점을 고려할 때 환자의 이동이 보장되고 설치위치에 제약을 받지 않도록 도시된 바와 같이 건전지나 내장 배터리 등을 통해 구동모터(111)가 내부적으로 전원을 제공받을 수 있도록 구성되는 것이 바람직하다.The main body 110 includes a driving motor 111 and a power supply unit 112 for supplying power to the driving motor 111. The power supply unit 112 may be configured to supply power to the driving motor 111 from an external power supply. However, considering that the present invention is installed on one side of the liquid hose C, It is preferable that the drive motor 111 is configured to be internally supplied with power through a battery or an internal battery as shown in the drawing so as not to be restricted by the installation position.
상기 본체(110)에 착탈가능하게 결합되는 키트(120)는 일측에 수액을 공급받는 수액유입구(123a)가 형성되고 타측에 공급받은 수액을 배출하는 수액배출구(123b)가 형성된다. 상기 수액유입구(123a)는 수액용기(A)와 연결된 제1수액호스(C1)의 단부에 연결된다. 그리고 상기 수액배출구(123b)는 주사바늘(B)과 연결된 제2수액호스(C2)의 단부에 연결된다. 아울러 상기 키트(120)의 내부에는 상기 구동모터(111)로부터 회전력을 전달받아 일측으로 회전하면서 수액유입구(123a)를 통해 유입되는 수액을 수액배출구(123b)로 이송시키는 이송스크류(122)가 설치된다.The kit 120 detachably coupled to the main body 110 is formed with a fluid inlet 123a for receiving the fluid on one side and a fluid outlet 123b for discharging the supplied fluid on the other side. The fluid inlet 123a is connected to the end of the first fluid hose C1 connected to the fluid receptacle A. And the fluid outlet 123b is connected to the end of the second infusion hose C2 connected to the needle B. [ A transfer screw 122 is installed in the kit 120 for transferring the rotational force from the driving motor 111 to the fluid inlet 123a and rotating the fluid inlet 123a to the fluid outlet 123b. do.
보다 상세하게 상기 키트(120)는 본체(110)에 착탈가능하게 결합되는 케이스(121a,121b)를 구비하며, 상기 케이스(121a,121b)의 내부에는 이송스크류(122)가 수직으로 긴밀하게 삽입되는 실린더(123)가 설치된다. 그리고 상기 실린더(123)의 측부에는 수액유입구(123a)가 일체로 연결되고 실린더(123)의 하부에는 수액배출구(123b)가 일체로 연결된다.More specifically, the kit 120 includes cases 121a and 121b that are detachably coupled to the main body 110, and the transfer screws 122 are vertically and tightly inserted into the cases 121a and 121b. A cylinder 123 is provided. A fluid inflow port 123a is integrally connected to the side of the cylinder 123 and a fluid inflow port 123b is integrally connected to a lower portion of the cylinder 123. [
상기 이송스크류(122)의 상단과 하단에는 각각 수액유입구(123a)로부터 수액이 유입되는 유입홈(122a)과 수액배출구(123b)로 이송된 수액이 배출되는 배출홈(122b)이 형성되어 있다.An upper end and a lower end of the conveying screw 122 are formed with an inlet groove 122a through which the sap flows from the sap inlet 123a and a drain groove 122b through which the sap transferred to the sap outlet 123b is discharged.
따라서, 상기 수액유입구(123a)와 수액배출구(123b)는 이송스크류(122)가 회전하는 과정에서 유입홈(122a)과 배출홈(122b)에 의하여 일정시간 동안만 주기적으로 개방되므로 일정한 양의 수액이 이송스크류(122)측에 공급되고 이송스크류(122)측으로부터 배출된다. 이때, 상기 수액유입구(123a)와 수액배출구(123b)는 동시에 개방되지 않는 위치에 형성되도록 한다. 이는 이송스크류(122)의 회전이 의도치 않게 중지될 경우에 동시 개방된 수액유입구(123a)와 수액배출구(123b)를 통해 수액이 지속적으로 환자에게 투입되거나 개방된 수액배출구(123b)와 수액유입구(123a)를 통해 혈액이 역류하는 사고가 발생되지 않도록 하기 위함이다.Therefore, since the liquid inlet 123a and the liquid outlet 123b are periodically opened for a predetermined period of time by the inlet groove 122a and the outlet groove 122b in the course of the rotation of the feed screw 122, Is supplied to the conveying screw 122 side and discharged from the conveying screw 122 side. At this time, the fluid inlet 123a and the fluid outlet 123b are formed at positions that are not opened at the same time. This is because when the rotation of the conveying screw 122 is inadvertently stopped, the liquid inlet 123a and the liquid outlet 123b simultaneously opened So that the blood does not flow back through the fluid outlet port 123b and the fluid inlet port 123a which are continuously inserted into the patient or opened through the fluid inlet port 123a.
한편, 도 4 내지 도 6에 도시된 바와 같이, 상기 이송스크류(122)는 회전축(122c)과, 실린더(123)에 밀착되도록 고무나 연질의 합성수지로 제작되어 상기 회전축(122c)에 끼워져 결합되는 스크류(122d)로 구성되며, 이송스크류(122)의 상부에는 키트(120)를 본체(110)에 결합시키는 과정에서 상기 구동모터(111)의 회전축(111a) 단부와 탄성적으로 연결되도록 탄성결합수단(130)이 구비된다.4 to 6, the conveying screw 122 is formed of rubber or soft synthetic resin so as to be in close contact with the cylinder 123 and is inserted into the rotation shaft 122c And the upper end of the transfer screw 122 is elastically coupled to the end of the rotation shaft 111a of the drive motor 111 in the process of coupling the kit 120 to the main body 110. [ Means 130 are provided.
상기 이송스크류(122)의 회전축(122c)은 하단이 실린더(123)의 바닥에 회전가능하게 삽입되어 이송스크류(122)가 실린더(123) 내부에서 안정적인 자세를 유지할 수 있도록 하는 것이 바람직하다. The lower end of the rotary shaft 122c of the feed screw 122 is rotatably inserted into the bottom of the cylinder 123 so that the feed screw 122 can maintain a stable posture in the cylinder 123. [
상기 이송스크류(122)는 수액배출구(123b)로 근접할수록 스크류(122d)의 축부 외경(D)이 점진적으로 증대되도록 형성하는 것이 좋다. 상기 축부 외경(D)이 점진적으로 커지게 됨에 따라서 스크류(122d)의 날개부의 높이는 점진적으로 작아진다. 또한, 상기 이송스크류(122)는 수액배출구(123b)로 근접할수록 스크류(122d)의 피치가 점진적으로 좁아지도록 하는 것이 바람직하다. 이와 같이 이송스크류(122)의 축부 외경(D)이 점진적으로 증대되게 하거나 수액배출구(123b)로 근접할수록 스크류(122d)의 피치가 점진적으로 좁아지도록 하는 이유는 수액의 이송압력이 수액배출구(123b)로 근접할수록 증대되게 하여 수액의 이송이 외부의 압력변화에 영향을 받지 않고 확실하게 이루어질 수 있도록 하기 위함이다.It is preferable that the feed screw 122 is formed such that the outer diameter D of the shaft portion of the screw 122d gradually increases as it approaches the liquid outlet 123b. As the shaft outer diameter D gradually increases, the height of the wing portion of the screw 122d gradually decreases. In addition, it is preferable that the pitch of the screw 122d gradually decreases as the feed screw 122 gets closer to the fluid outlet 123b. The reason why the pitch of the screw 122d is gradually narrowed as the outer diameter D of the shaft portion of the feed screw 122 gradually increases or gets closer to the liquid outlet 123b is that the feed pressure of the liquid passes through the liquid outlet 123b So that the transfer of the liquid can be surely performed without being influenced by the external pressure change.
아울러, 상기 소켓(131)의 하부 외주면에는 실린더(123) 내주면에 밀착되는 밀착돌기(131c)가 형성되어 수액유입구(123a)를 통해 실린더(123) 내부로 유입된 수액이 이송스크류(122) 상부로 역류하여 실린더(123) 외부로 유출되지 않도록 하는 것이 바람직하다.A contact protrusion 131c is formed on the outer circumferential surface of the lower portion of the socket 131 so as to be brought into close contact with the inner circumferential surface of the cylinder 123. A liquid inflow into the cylinder 123 through the fluid inlet 123a is transferred to the upper portion of the transfer screw 122 So as not to flow out to the outside of the cylinder 123.

In this case, the fixed cap 134 should be made of a stretchable material.
본 실시예에서는 승강부재(133)의 상단에 요부(133a)가 형성되고 구동모터(111)의 회전축(111a) 단부에 돌부(111b)가 형성되도록 하였으나, 이와 반대로 형성되어도 무방하다. 아울러, 보다 원활한 돌부(131b)와의 맞물림을 위하여 상기 승강부재(133)의 상단면(133c)은 상기 요부(133a)를 향해 하향경사지게 형성되는 것이 바람직하다.The concave portion 133a is formed at the upper end of the lifting member 133 and the protrusion 111b is formed at the end of the rotating shaft 111a of the driving motor 111. However, It is preferable that the upper end surface 133c of the elevating member 133 is formed to be inclined downward toward the recess 133a in order to engage with the smooth protrusion 131b.
한편, 도 2 및 도 3에 도시된 바와 같이, 상기 케이스(121a,121b)는 사용상의 편의를 위하여 본체(110)에 슬라이딩 결합되도록 상기 본체(110)의 일측에는 키트(120)를 수용할 수 있는 절취부(110a)가 형성되고, 상기 절취부(110a)의 일측에는 수직레일부(113)가 형성되며, 상기 키트(120)의 케이스(121a,121b) 일측에는 상기 수직레일부(113)를 따라 슬라이딩 결합되는 수직홈부(124)가 형성될 수 있다.2 and 3, the case 121a and 121b can receive the kit 120 at one side of the main body 110 to be slidably coupled to the main body 110 for convenience of use.

[
이와 같이 구성된 본 발명의 수액 정량 공급장치는 다음과 같이 사용된다.The thus configured liquid quantity dispenser of the present invention is used as follows.
먼저, 키트(120)에 형성된 수액유입구(123a)에 수액용기(A)와 연결된 제1수액호스(C1)를 연결하고 상기 수액배출구(123b)에는 주사바늘(B)과 연결된 제2수액호스(C2)를 연결한 다음 본체(110)의 절취부(110a)의 하부에 키트(120)를 위치시킨 다음 밀어올리게 되면, 키트(120)에 형성된 수직홈부(124)가 절취부(110a)에 형성된 수직레일부(113)에 끼워지면서 키트(120)가 본체(110)에 슬라이딩 결합된다. 이 과정에서 본체(110)에 구비된 구동모터(111)의 회전축(111a)과 키트(120)에 구비된 이송스크류(122)가 상호 결합된다.The first fluid hose C1 connected to the fluid receptacle A is connected to the fluid inlet 123a formed in the kit 120 and the second fluid hose C1 connected to the injection needle B is connected to the fluid outlet 123b. C2 is connected to the cutout 110a of the main body 110 and then the kit 120 is positioned at the lower portion of the cutout 110a of the main body 110, The kit 120 is slidably engaged with the main body 110 while being fitted to the vertical rail part 113. [ The rotating shaft 111a of the driving motor 111 provided in the main body 110 and the feeding screws 122 provided in the kit 120 are coupled to each other.
이와 같이 본체(110)에 키트(120)가 결합되면, 사용자는 본체(110) 전면에 구비된 컨트롤부(110c)를 이용하여 구동모터(111)를 동작시키고 이송스크류(122)의 회전속도를 적절하게 조절하여 수액의 투입속도를 셋팅한다.When the kit 120 is coupled to the main body 110 as described above, the user operates the drive motor 111 using the control unit 110c provided on the front surface of the main body 110 and adjusts the rotation speed of the feed screw 122 Adjust the infusion rate of the liquid appropriately.
한편, 구동모터(111)와 이송스크류(122)의 상호결합은 구동모터(111)의 회전축(111a) 단부에 형성된 돌부(111b)와 이송스크류(122) 상단에 설치된 승강부재(133)에 형성된 요부(133a)가 서로 맞물리며 이루어지게 되는데, 상기 회전축(122c)과 승강부재(133)는 회전이 자유로운 상태이므로 도 6에 도시된 상태와 같이 본체(110)에 키트(120)를 결합시킬 때 회전축(122c) 단부에 형성된 돌부(111b)와 승강부재(133)의 축연결부에 형성된 요부(133a)가 정확하게 맞물리지 않을 수 있다.The mutual engagement of the drive motor 111 and the feed screw 122 is formed by the protrusion 111b formed at the end of the rotary shaft 111a of the drive motor 111 and the elevation member 133 provided at the upper end of the feed screw 122 The rotation shaft 122c and the elevating member 133 are free to rotate so that when the kit 120 is coupled to the main body 110 as shown in FIG. 6, The projected portion 111b formed at the end of the elevating member 122c and the recessed portion 133a formed at the shaft connecting portion of the elevating member 133 may not be correctly engaged.
이와 같이 요부(133a)와 돌부(111b)가 정확하게 맞물리지 않은 경우에는 승강부재(133)가 회전축(111a) 단부에 눌리면서 하강한 상태로 본체(110)에 키트(120)가 결합되는데, 이후 구동모터(111)가 동작되면 회전축(111a)이 회전하면서 자연스럽게 돌부(111b)와 요부(133a)가 맞물림이 가능한 상태로 정렬된다. 상기 돌부(111b)와 요부(133a)가 맞물림이 가능한 상태로 정렬되면, 승강부재(133)에 가해졌던 압축력이 제거되면서 압축되었던 승강부재(133)가 원래 위치로 상승하게 되므로 요부(133a)와 돌부(111b)의 맞물림은 정상적으로 이루어지게 된다. 이때, 승강부재(133)의 상단면(133c)이 요부(133a)를 향해 하향경사지게 형성된 경우, 상기 요부(133a)와 돌부(111b)의 맞물림은 매우 원활하게 이루어지게 된다.When the recess 133a and the protrusion 111b are not correctly engaged with each other, the kit 120 is coupled to the main body 110 in a state where the lifting member 133 is pushed down by the end of the rotating shaft 111a, The rotation shaft 111a is rotated to naturally align the protrusion 111b and the recess 133a with each other. When the protrusion 111b and the concave portion 133a are aligned with each other, the pressing force applied to the lifting member 133 is removed and the lifted member 133 is lifted to the original position. The engaging of the protruding portion 111b is normally performed. At this time, when the upper end surface 133c of the lifting member 133 is inclined downward toward the concave portion 133a, the concave portion 133a and the convex portion 111b are engaged with each other very smoothly.
이와 같이 구동모터(111)의 회전축(111a)과 이송스크류(122)가 정상적으로 결합된 상태에서 구동모터(111)의 회전축(111a)으로부터 회전력을 부여받아 사용자가 설정한 속도로 이송스크류(122)가 회전하게 되면, 수액유입구(123a)가 이송스크류(122)의 회전각도에 따라 주기적으로 개폐되면서 수액유입구(123a)가 개방되는 동안만 이송스크류(122)측으로 수액이 공급된다. 이때의 실린더(123)의 내부는 이송스크류(122)의 동작에 의하여 제1수액호스(C1) 보다 저압이므로 수액유입구(123a)를 통해 유입되는 수액은 수액용기(A) 내에 저장된 수액양의 변화나 수용용기의 거치위치에 상관없이 항상 원활하게 이루어지게 된다.When the rotation shaft 111a of the driving motor 111 and the conveying screw 122 are normally engaged with each other, a rotational force is applied from the rotational axis 111a of the driving motor 111 to the conveying screw 122 at a speed set by the user, The liquid inflow port 123a is periodically opened and closed according to the rotation angle of the feed screw 122 and the liquid is supplied to the feed screw 122 only while the liquid inflow port 123a is opened. Since the interior of the cylinder 123 at this time is lower in pressure than the first fluid hose C1 due to the operation of the feed screw 122, the fluid flowing through the fluid inlet 123a flows into the cylinder 123, Regardless of the position of the container or the mounting position of the container.
이와 같이, 이송스크류(122)측으로 유입된 수액은 스크류(122d)를 따라 수액배출구(123b)로 이송된다. 이때, 스크류(122d)의 피치가 점진적 좁아지게 형성되거나 이송스크류(122)의 축부 외경(D)이 점진적으로 증대되도록 하면, 수액의 이송압력이 점진적으로 높아지면서 수액배출구(123b)로의 이송압력이 커지게 된다. 따라서 이송되는 수액은 이송 중 이송압력이 약해 실린더(123) 내부에서 정체되거나 역류하지 않고 수액배출구(123b)를 통해 제2수액호스(C2)로 원활하게 빠져나가게 된다.Thus, the liquid introduced into the side of the conveying screw 122 is conveyed along the screw 122d to the liquid outlet 123b. At this time, if the pitch of the screw 122d is gradually reduced or the outer diameter D of the shaft portion of the feed screw 122 is gradually increased, the feed pressure to the liquid outlet 123b gradually increases as the feed pressure of the liquid gradually increases . Accordingly, the transferred liquid is smoothly transferred to the second liquid hose C2 through the liquid discharge port 123b without being stagnated or flowing backward in the cylinder 123 due to the weak transfer pressure during transfer.
따라서, 수액용기(A)와 주사바늘(B)을 연결하는 수액호스(C) 사이에 본 발명의 수액 정량 공급장치가 설치되면, 별도의 수액조절장치 없이도 수액용기(A) 내에 저장된 수액양의 변화나 수용용기(A)의 거치위치에 상관없이 항상 목표로 하는 시간 동안 정량의 수액을 환자에게 투여할 수 있게 되므로 사용이 매우 간편하며 치료효과도 향상될 수 있다.Therefore, when the fixed amount supply device of the present invention is provided between the liquid hoses C connecting the liquid container A and the needles B, the amount of liquid stored in the liquid container A It is possible to administer a predetermined amount of liquid to the patient at any desired time regardless of the position of the changeable container or receptacle (A), so that it is very easy to use and the therapeutic effect can be improved.
이와 같이, 도면을 참조하여 본 발명의 바람직한 실시예에 대해 상술하였으나 본 발명은 전술한 실시예에 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진자가 본 발명의 사상을 벗어나지 않고 변형 가능하며, 이러한 변형은 본 발명의 권리범위에 속할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be takeners of ordinary skill in the art, And such variations are within the scope of the present invention.
