본 고안은 링거액이 모두 소진된 것을 감지하여 경보신호를 발생하고 동시에 링거액 관로를 막아서 공기 유입을 차단해주는 무전원(無電源) 링거액 소진(消盡) 경 보 장치에 관한 것으로, 상기의 다양한 기능을 위해 어떠한 전원도 필요로 하지 않는다는 것을 특징으로 한다.The present invention relates to a non-powered ringer fluid exhaustion alarm device which detects the exhaustion of the ringer fluid and generates an alarm signal and simultaneously blocks the ringer fluid conduit to block air inflow. It does not require any power source.
Description
본 고안은 점적부 내의 링거액이 소진된 것을 감지하여 소리나 빛과 같은 경보 신호를 발생하고 동시에 링거액 관로를 막아서 공기 유입을 차단해주는 무전원(無電源) 링거액 소진 경보 및 공기 유입 차단 장치에 관한 것이다. The present invention relates to a non-powered ringer fluid exhaustion alarm and an air inflow blocking device that detects the exhaustion of the ringer liquid in the drop portion and generates an alarm signal such as sound or light, and at the same time, blocks the air flow by blocking the ringer liquid pipe.
종래의 링거액 소진 경보 장치로는,In the conventional Ringer's liquid exhaustion alarm device,
광센서를 감지 수단으로 이용한 장치는 광센서의 조도변화를 감지하는 방식으로 링거액의 색상이나 투명도에 영향을 받고, 링거용기의 내부에 전극을 삽입시켜 전류를 감지토록 하는 장치는 이물질, 세균 등의 오염에 노출되고, 링거 용기의 외벽에 정전 용량 센서를 부착하여 링거용기 내부의 액체 유무를 판단하는 장치는 제작 비용이 많이 들고 링거 용기 재질의 종류에 영향을 받는 단점이 있다. 더구나 상술한 종래의 장치들은 전원을 필요로 하는 전자 센서를 이용하기 때문에 전원이 근처에 있어야 하는 등의 설치 장소의 제약이 있거나 수시로 장치에 내장된 배터리를 충전(또는 충전)해 주어야 하는 단점이 있다. 이를 보완하기 위해 링거액이 들어 있는 링거 용기의 무게의 변화를 기계식 센서를 사용하여 감지하는 방식이 존재하나 그 구조가 너무 복잡하고, 부피가 너무 커서 설치 및 휴대가 용이치 않으며, 경보 신호 발생을 위해 별도의 전원이 필요하다는 단점이 있다.The device that uses the light sensor as a sensing means detects the change in illuminance of the light sensor and is affected by the color or transparency of Ringer's solution. Exposed to contamination, the device for determining the presence of the liquid inside the ringer container by attaching a capacitive sensor on the outer wall of the ringer container has a disadvantage in that the manufacturing cost and the type of ringer container material is affected. In addition, the above-described conventional devices use an electronic sensor that requires a power source, and thus, there are limitations in the installation place such as the power source being nearby or a need to charge (or charge) the battery built in the device from time to time. . In order to compensate for this, there is a method of detecting the change in the weight of the Ringer's container containing Ringer's solution by using a mechanical sensor, but its structure is too complicated, the volume is too large, so it is not easy to install and carry. The disadvantage is that a separate power supply is required.
종래의 공기 유입 차단 장치로는,As a conventional air inflow shutoff device,
부력과 중력을 이용하여 링거액이 있을 시에는 부력에 의해 밸브가 개방되어지고 링거액이 없을 시에는 중력에 의해 밸브가 차단되어지는 원리를 이용한 다양한 구조의 장치들이 있으나, 링거액의 소진을 감지해서 링거 용기의 교체 시기를 알려 주는 경보 기능이 없다는 단점이 있다.There are various types of devices using the principle that the valve is opened by buoyancy when there is Ringer's fluid by buoyancy and gravity, and the valve is blocked by gravity when there is no Ringer's fluid. The disadvantage is that there is no alarm function to indicate when to replace.
따라서, 본 고안은 상술한 바와 같은 종래의 링거액 소진 경보 장치와 종래의 공기 유입 차단 장치들의 문제점을 일시에 해결하기 위해 안출한 것으로, Therefore, the present invention is devised to solve the problems of the conventional ringer liquid exhaustion alarm device and the conventional air inflow blocking device as described above at one time,
본 고안의 목적은 전원이 없이도 링거액의 잔량 여부를 판단해서 경보 신호를 보내주고 공기 유입 차단을 위해 관로를 차단해 줄 수 있는 무전원 링거액 잔량 감지 및 공기 유입 차단 장치를 제공하는 데에 있으며, 이하 첨부된 도면에 의거 본 고안의 구성 및 작용을 상세히 설명하면 다음과 같다. An object of the present invention is to provide a non-powered Ringer liquid level detection and air inlet blocking device that can determine the remaining amount of Ringer's fluid without power and send an alarm signal and block the pipeline for blocking the inflow of air. Referring to the configuration and operation of the present invention in detail based on the drawings as follows.
본 고안에서 예시되는 제 1 실시 예는 도 1에서 도시된 바와 같이, 점적부(1) 내부에서 부력과 중력의 상호 작용에 의해 상하 운동을 하는 원통(2)과, 점적부 외측 하단에 설치된 하우징(6) 속에 놓여져 있는 영구 자석(7)과, 태엽(13)과 오르골(orgol)(15, 18)로 구성된 멜로디 발생 장치와, 태엽의 힘을 이용하여 관로(10)를 눌러 주는 누름핀(16)으로 구성된 링거액 잔량 감지 장치에 대한 것이다. As illustrated in FIG. 1, the first embodiment illustrated in the present invention includes a cylinder 2 which vertically moves by buoyancy and gravity interaction inside the drop portion 1, and a housing installed at the lower end of the drop portion. (6) a melody generating device composed of a permanent magnet (7), a spring (13) and an orgol (15, 18), and a push pin that presses the conduit 10 using the force of the spring. It is for the ringer liquid level detection device consisting of 16).
도 2A는 본 고안 제 1 실시 예에 의한 링거액 소진 경보 장치의 단면을 보인 도면으로서, 원통(2)이 받는 부력을 크게 하기 위하여 원통 속에는 공동(空洞)(4)이 형성되어 있으며, 링거액이 소진되면서 원통이 중력에 의해 점적부의 하단으로 내려 갔을때 점적부 외측에 놓여 있는 영구자석(7)을 원통이 끌어 당길 수 있도록 원통 속에는 얇은 환형 금속 띠(3)가 삽입되어 있다. FIG. 2A is a cross-sectional view of the ringer liquid exhaustion warning device according to the first embodiment of the present invention. In order to increase the buoyancy received by the cylinder 2, a cavity 4 is formed in the cylinder, and the ringer liquid is exhausted. When the cylinder descends to the bottom of the drop by gravity, a thin annular metal band (3) is inserted into the cylinder so that the cylinder can pull the permanent magnet (7) placed on the outside of the drop.
도 2B에서 도시된 바와 같이, 링거액(5)이 소진되면서 원통이 중력에 의해 점적부의 맨 하단으로 내려갔을때 원통 속의 금속 띠(3)와 영구자석(7) 간의 상호 인력에 의해 영구자석(7)은 왼쪽으로 이동하게 되고, 도 2A에서 도시된 바와 같이 점적부 내에 링거액(5)이 차게 되면 원통(2)은 부양하게 되고 영구자석(7)은 스프링(8)에 의해 원래 위치로 복원되어 진다. As shown in FIG. 2B, when the ringer fluid 5 is exhausted and the cylinder descends to the bottom of the drop by gravity, the permanent magnet 7 is formed by mutual attraction between the metal band 3 and the permanent magnet 7 in the cylinder. Is moved to the left and, as shown in FIG. 2A, when the Ringer's fluid 5 is filled in the dropping portion, the cylinder 2 is supported and the permanent magnet 7 is restored to its original position by the spring 8. .
다시 도 1을 살펴 보면, 영구자석(7) 하단에 있는 금속 재질의 스위치(12)는 영구자석과 같이 움직이면서, 도 2A에서 보여지는 스위치 위치에서는 감겨진 태엽(13)이 풀리지 않도록 태엽을 구속하는 역할을 하며, 링거액 소진에 의해 영구자석(7)이 왼쪽으로 이동하게 되면, 스위치(12)도 왼쪽으로 이동하면서 감겨진 태엽(13)이 풀리도록 하는 역할을 한다. 상기 태엽이 풀리는 회전력은 오르골의 원통(18)을 회전시켜서 멜로디와 같은 경보 신호를 보내주며, 아울러 상기 태엽의 회전 운동은 하우징(11) 내부에 설치되어 있는 기어 박스(일종의 동력변환장치)를 거치면서 누름핀(16)이 왼쪽으로 직선 운동을 하도록 하여, 누름핀(16)과 받침판(17) 사이에 놓여 있는 관로(10)를 차단하게 된다. Referring back to FIG. 1, the switch 12 made of metal at the bottom of the permanent magnet 7 moves like a permanent magnet, restraining the mainspring so that the wound spring 13 is not released at the switch position shown in FIG. 2A. When the permanent magnet 7 is moved to the left by the exhaustion of the Ringer's liquid, the switch 12 also moves to the left and serves to unwind the wound winding 13. The rotating force of the winding spring rotates the cylinder 18 of the music box to send an alarm signal such as a melody, and the rotating movement of the winding spring passes through a gear box (a kind of power converter) installed inside the housing 11. While the push pin 16 is linearly moved to the left, the push pin 16 blocks the conduit 10 lying between the push pin 16 and the support plate 17.
한편, 링거액 소진 후 링거액을 새로 교체하게 되면, 태엽(13)을 다시 감아 놓아서 나중에 링거액 소진시 태엽이 회전력을 발생시킬 수 있도록 해주며, 상기 태엽을 감는 과정에 의해 누름핀(16)이 오른쪽으로 이동되면서 차단되었던 관로가 열리게 된다. On the other hand, when Ringer's fluid is newly replaced after Ringer's fluid is exhausted, the winding of the mainspring (13) is re-wound so that when the Ringer's fluid is exhausted later, the spring can be generated. As the movement moves, the blocked pipeline is opened.
본 고안에서 예시되는 제 2 실시 예는 도 3A에서 도시된 바와 같이 센서 역할을 하는 영구 자석의 설치 위치를 도 2와 다르게 변경한 것으로, 점적부(1) 내부에서 부력과 중력의 상호 작용에 의해 상하 운동을 하는 원통(22)과, 점적부 하단 외측에 설치된 하우징(20) 내부에 놓여 있는 환형 영구자석(21)으로 구성된 링거액 잔량 감지 장치에 관한 것이다. 원통(22)의 내부는 공동(24)과 얇은 금속 원형 판(23)으로 구성되어 있으며, 링거액이 소진되어 원통이 점적부 하단으로 내려가게 되면 도 3B에서 도시된 바와 같이 원통(22)과 영구자석(21) 간에는 상호 인력이 발생하게 되어 영구자석(21)은 위쪽으로 상승하게 되고, 링거액이 다시 점적부 내부에 채워지게 되면 부력에 의해 원통(22)은 부양되게 된다. 결과적으로 링거액 유무에 따라 상하 운동을 하는 영구자석(21) 근처에 스위치(12)를 설치하게 되면, 제 1 실시 예와 같은 개념의 링거액 잔량 감지 및 공기 유입 차단 장치가 구성되게 된다.As illustrated in FIG. 3A, the second exemplary embodiment of the present invention changes the installation position of the permanent magnet serving as a sensor, as shown in FIG. 3A, differently from FIG. 2. The present invention relates to a ringer liquid remaining amount sensing device including a cylinder 22 for up and down movement and an annular permanent magnet 21 placed inside a housing 20 installed outside the bottom of the drop portion. The inside of the cylinder 22 is composed of a cavity 24 and a thin metal circular plate 23, and when the ringer liquid is exhausted and the cylinder is lowered to the bottom of the drop portion, the cylinder 22 and the permanent as shown in Figure 3B The mutual attraction is generated between the magnets 21 so that the permanent magnets 21 rise upwards, and when the ringer liquid is filled in the drop portion again, the cylinder 22 is buoyed by buoyancy. As a result, when the switch 12 is installed near the permanent magnet 21 that moves up and down in accordance with the presence or absence of Ringer's solution, the Ringer's solution remaining amount detection and air inflow blocking device according to the first embodiment is configured.
한편, 상기의 제 2 실시 예의 경우, 제 1 실시 예와는 달리 별도의 튜브 누름 장치(17, 16)를 사용하지 않고, 도 3B에서 도시된 바와 같이 원통(22)이 영구자석(21)의 인력에 의해 점적부의 하단에 강하게 밀착되도록 하는 방법에 의해 자동으로 점적부 출구(25)가 막혀지도록 하여 관로가 차단되도록 하는 방안이 이용될 수 있다.On the other hand, in the case of the second embodiment, unlike the first embodiment, without using a separate tube pressing device (17, 16), as shown in FIG. 3B the cylinder 22 of the permanent magnet 21 A method of automatically blocking the dropout outlet 25 by a method of tightly contacting the bottom of the dropper by the attraction force may block the conduit.
상술한 바와 같이 본 고안은 링거액의 공급이 완료될 경우 자동으로 경보 신호를 보내주고 관로를 차단해주기 때문에, 적절한 시기에 링거액의 교체가 가능케 하고 자동으로 공기 유입을 차단해주는 효과가 있다. 특히, 본 고안은 전기를 필요로 하지 않기 때문에 전원 공급을 위한 설치 장소의 제약과 배터리 교체의 번거로움 및 교체 비용 등의 문제점을 일시에 해결해주는 효과를 제공한다.As described above, the present invention automatically sends an alarm signal when the supply of the Ringer's solution is completed and blocks the conduit, thereby enabling the replacement of the Ringer's solution at an appropriate time and automatically blocking the inflow of air. In particular, since the present invention does not require electricity, it provides an effect of temporarily solving the problems such as the limitation of the installation site for power supply and the hassle and replacement cost of battery replacement.
