Description

자동 수액 공급장치{Automatic injection feeder}[0001] Automatic injection feeder [0002]

본 발명은 인체에 수액을 주입하는 수액 공급장치에 관한 것으로, 일정 높이에 위치되어 중력에 의해 주입되는 중력식 수액 공급장치 또는 손으로 압력을 가하는 수동식 펌핑 장치가 구비된 수액 공급장치의 문제점을 해결하여, 보다 편리하고 안정적이며 고른 압력으로 수액을 공급할 수 있도록 구성된 자동 수액 공급장치에 관한 것이다.
The present invention relates to a liquid supply device for injecting a liquid into a human body, which solves the problem of a liquid supply device provided with a gravity type liquid supply device which is located at a certain height and is injected by gravity or a manual pumping device which applies pressure by hand And more particularly, to an automatic liquid supply device configured to supply liquid at a more convenient, stable, and even pressure.

수액을 환자에게 공급하기 위하여는 수액의 주입 압력이 환자의 혈액 압력보다 높아야 한다. 따라서 종래의 경우 수액을 담은 백(bag, 이하 '수액백'이라 함)을 혈액 압력에 의해 수액이 역류되지 않을 정도의 높은 위치에 위치되도록 행거 등에 걸어 두고, 수액줄에 유량조절기를 설치하여 수액줄의 관경을 조절함으로써 수액의 투여량을 조절하였다.In order to supply the fluid to the patient, the injection pressure of the fluid should be higher than the blood pressure of the patient. Therefore, in the conventional case, a bag (hereinafter, referred to as a "liquid bag") containing the liquid is hung on a hanger or the like so as to be located at a high position where the liquid does not flow back by the blood pressure, The dose of the liquid was adjusted by controlling the diameter of the line.

이러한 중력에 의한 수액의 투여는 수액백의 높이에 따라 수액의 흐름량이 달라지므로, 수액백이 위치가 달라지면 그때마다 유량조절기를 조절하여야 하고 유량조절기는 잘 풀리는 경우가 있어 항상 관찰하여야 한다.Since the flow of sap flows depending on the height of the fluid bag, it is necessary to control the flow controller whenever the position of the fluid bag changes, and the flow controller should be always observed.

이와 같은 중력식 수액 공급장치는 일정한 주입량으로 관리하기가 번거로워 공기 압력을 이용한 수액 주입장치가 개시되어 있다. 즉, 수액백과, 수액백의 외부에 기밀되게 감싸도록 설치된 하우징과, 수액백과 하우징의 사이 공간인 가압실에 공기를 주입하여 수액백을 압박하는 수동식 펌프와, 가압실의 압력을 계측하는 압력계와, 수액백과 주사바늘을 연결하는 수액줄을 포함하여 구성된다.Such a gravity type liquid supply device is troublesome to manage with a constant injection amount, and thus a liquid injection device using air pressure is disclosed. That is, there are provided a liquid bag, a housing provided to hermetically enclose the liquid bag, a manual pump for injecting air into the pressurizing chamber, which is a space between the liquid bag and the housing, for pressing the bag, a pressure gauge for measuring the pressure in the pressurizing chamber, And an infusion line connecting the infusion bag and the injection needle.

상기와 같은 종래의 공기압을 이용한 수액 주입장치는 혈액 압력보다 적당히 높은 압력을 가지도록 수액백을 가압하여 수액이 주입되도록 하는데, 이는 손으로 눌러 펌핑하는 펌프에 의해 가압실의 공간에 공기를 가압하여 이루어졌다.
The conventional infusion apparatus for infusion of pneumatic fluid as described above pressurizes the infusion bag so as to have a moderately higher pressure than the blood pressure so that the infusion fluid is injected by pushing air into the space of the pressurization chamber by a pump .

종래의 공기압을 이용한 수액 공급장치는 하우징의 내부에 수액백이 설치되고, 가압실에 공기를 주입하여 그 공기압이 수액백을 가압하도록 하여 수액을 배출하도록 하는 장치였다. 즉, 가압실의 가압은 손으로 눌러 공기를 펌핑하는 핸드 블로어와 같은 구조의 수동 펌프가 사용되었고, 수동 펌프의 가압시에는 가압실에 설치된 압력계를 보면서 작동하였다.Conventionally, a liquid supply device using air pressure is a device in which a liquid bag is provided inside a housing, air is injected into the pressure chamber, and the air pressure pressurizes the liquid bag to discharge the liquid. That is, a manual pump having a structure similar to that of a hand blower for pumping air by pressing with a hand was used for the pressurization of the pressurizing chamber, and a pressure gauge installed in the pressurizing chamber was operated when the manual pump was pressurized.

이와 같이 종래의 경우, 펌프로 펌핑하여 수액백이 일정 압력으로 가압되도록 하면, 가압력에 의해 수액백이 압축되면서 수액이 수액줄을 따라 흘러가게 된다. 그러나, 수액이 수액백에서 빠져 나가게 되면 가압실의 압력이 떨어져 수액의 흐름량이 줄어들게 되므로, 항상 가압실의 압력을 주시하면서 압력이 떨어지면 펌핑하여야 하는 번거로움이 있었다.Thus, in the conventional case, when the liquid bag is pumped by the pump and the liquid bag is pressed at a constant pressure, the liquid bag is compressed by the pressing force, and the liquid flows along the liquid bag. However, when the liquid is discharged from the liquid bag, the pressure in the pressurizing chamber drops and the flow amount of the liquid is reduced. Therefore, it is troublesome to pump the pressure when the pressure in the pressurizing chamber is constantly monitored.

따라서 본 발명은 수액백의 설치 높이와 무관하고, 항상 일정한 압력이 가압실에 가해져 일정량의 수액이 주입될 수 있도록 하되, 간호사나 간병인의 관찰과 수동 펌핑이 없이도 자동으로 수액백을 가압하는 압력이 일정하게 조절되도록 하는 자동 수액 공급장치를 제공함에 목적이 있다.
Therefore, the present invention is independent of the installation height of the fluid bag, and is constantly applied to the pressurizing chamber so that a certain amount of fluid can be injected. However, even if the nurse or caregiver observes and the manual pumping is not performed, And a control unit for controlling the operation of the automatic liquid supply device.

상기의 목적을 달성하기 위하여 본 발명은 가압실에 공기를 주입하여 수액백을 가압하는 에어펌프와, 가압실의 압력을 계측하는 압력센서와, 입력된 특정 압력과 압력센서에 의해 계측된 압력을 비교하여 에어펌프를 제어함으로써 가압실의 압력을 일정하게 유지시키도록 하는 제어장치를 포함하여 구성된 자동 수액 공급장치를 제공하게 된다.
According to an aspect of the present invention, there is provided an air bag comprising: an air pump for injecting air into a pressurizing chamber to pressurize the bag, a pressure sensor for measuring a pressure of the pressurizing chamber, And controlling the air pump so as to maintain the pressure of the pressurizing chamber at a constant level.

본 발명에 따르면, 수액백의 설치 높이에 상관없이 항상 일정한 압력으로 수액을 공급할 수 있으므로, 종래 중력식이나 수동식의 경우 압력 관리가 안되어 혈액이 역류하는 문제를 해소하고, 수액 공급 관리가 매우 간편하게 이루어지며, 이러한 것들에 의해 의사의 처방대로 정확하게 수액이 공급되어 환자의 다양한 시술이나 치료에 효과가 있다.
According to the present invention, it is possible to supply the liquid at a constant pressure regardless of the installation height of the liquid bag. Therefore, in the conventional gravity type or manual type, the problem of the back flow of the blood due to no pressure control can be solved, By these things, the liquid is supplied exactly according to the doctor's prescription, and it is effective for various treatment and treatment of the patient.

도 1은 본 발명의 전체 구성도BRIEF DESCRIPTION OF THE DRAWINGS FIG.

본 발명에 의한 자동 수액 공급장치는 수액줄(1)과 연결되고 수액이 담긴 수액백(2)과, 수액백(2)의 외부를 감싸도록 설치된 하우징(3)과, 수액백(2)과 하우징(3) 사이에 형성된 가압실(4)에 튜브(5)로 연결되어 공기를 주입하여 수액백(2)을 가압하는 에어펌프(6)와, 가압실(4) 또는 튜브(5)에 설치되어 압력을 계측하는 압력센서(7)와, 입력된 특정 압력과 압력센서(7)에 의해 계측된 압력을 비교하여 에어펌프(6)를 제어함으로써 가압실(4)의 압력을 일정하게 유지시키도록 하는 제어장치(8)와, 튜브(5)의 관로상에 설치되어 수액이 에어펌프(6)쪽으로 역류되는 것을 방지하는 체크밸브(9)로 구성된다.The automatic fluid dispensing apparatus according to the present invention comprises a fluid bag 2 which is connected to a fluid bag 1 and contains an infusion fluid, a housing 3 installed to surround the outside of the fluid bag 2, a fluid bag 2, An air pump 6 connected to the pressurizing chamber 4 formed between the housings 3 by a tube 5 to inject air and pressurize the infusion bag 2, The pressure of the pressurizing chamber 4 is controlled to be constant by controlling the air pump 6 by comparing the pressure measured by the pressure sensor 7 with the specific pressure inputted And a check valve 9 provided on the channel of the tube 5 for preventing the liquid solution from flowing back to the air pump 6 side.

상기의 가압실(4)에는 압력계(10)가 설치될 수도 있는데, 이는 환자나 간호사나 간병인 등이 쉽게 가압실(4)의 압력을 관찰할 수 있도록 함이다.A pressure gauge 10 may be provided in the pressurization chamber 4 so that a patient, a nurse, a caregiver, etc. can easily observe the pressure of the pressurization chamber 4.

상기와 같이 에어펌프(6)를 이용하여 수액백(2)을 가압하고, 일정한 압력이 유지되도록 압력센서(7)와 제어장치(8)에 의해 제어됨으로써, 수액백(2)의 설치 높이나 위치에 상관없이 일정한 압력에 의해 일정한 유량의 수액이 공급된다.The infusion bag 2 is pressed by using the air pump 6 and controlled by the pressure sensor 7 and the control device 8 so that a constant pressure is maintained so that the installation height or position of the infusion bag 2 A constant flow rate of the liquid is supplied by a constant pressure regardless of the flow rate.

이하 도면을 참조하여 본 발명의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described with reference to the drawings.

도 1에 도시된 바와 같이, 수액백(2)은 수액줄(1)과 연결되어 환자나 시술자에게 주입되는데, 수액을 주입하기 위한 압력은 수액백(2)을 가압하여 얻게 된다. 본 발명은 수액백(2)의 가압이 에어펌프(6)에 의한 공기압으로 수액백(2)을 가압하는 구조이다.As shown in FIG. 1, the infusion bag 2 is connected to the infusion line 1 and is injected into the patient or the practitioner. The pressure for injecting the infusion solution is obtained by pressing the infusion bag 2. The present invention is a structure in which pressurization of the fluid bag (2) pressurizes the fluid bag (2) by air pressure by the air pump (6).

우선, 혈액 압력보다 높은 압력으로 가장 이상적인 수액의 주입 압력을 제어장치(8)를 통해 설정한다. 제어장치(8)는 가압실(4)의 유지 압력을 일정 범위에서 설정하고, 그 설정치에 드는 경우 에어펌프(6)의 작동을 멈추고, 작을 경우 작동시켜 항상 일정한 압력이 가압실(4)에 작용하도록 제어한다.First, the injection pressure of the ideal fluid is set through the control device 8 at a pressure higher than the blood pressure. The control device 8 sets the holding pressure of the pressurizing chamber 4 within a certain range and stops the operation of the air pump 6 when the set value is reached, .

제어장치(8)에 압력치가 설정된 후, 본 발명의 장치가 작동되면, 가압실(4)의 압력은 압력센서(7)에 의해 계측되고, 이의 수치는 제어장치(8)에서 설정치와 비교된 후, 설정치 보다 작은 경우 에어펌프(6)를 작동시킨다.When the apparatus of the present invention is operated after the pressure value is set in the control device 8, the pressure in the pressurizing chamber 4 is measured by the pressure sensor 7, and its numerical value is compared with the set value in the control device 8 Thereafter, when it is smaller than the set value, the air pump 6 is operated.

에어펌프(6)는 공기를 가압실(4)로 송급하여 밀폐된 가압실에 압력을 높이게 되고, 가압실(4)의 내부에 설치된 수액백(2)을 눌러 수액을 배출시키는 역할을 하게 된다. 물론 에어펌프(6)는 실린더, 모터 등의 다양한 구조로 형성될 수 있고, 공기를 송급하는 역할을 하는 것이라면 어떠한 구조라도 가능하다.The air pump 6 feeds the air to the pressurizing chamber 4 to increase the pressure in the closed pressurizing chamber and presses the liquid bag 2 installed in the pressurizing chamber 4 to discharge the liquid . Of course, the air pump 6 may be formed in various structures such as a cylinder and a motor, and any structure may be used as long as it serves to feed air.

에어펌프(6)가 작동을 하면, 튜브(5)를 따라 공기기 흘러 하우징(3)과 수액백(2)의 사이 공간인 가압실(4)로 송급된다. 가압실(4)에 공기가 유입됨으로써 가압실(4)의 압력은 높아지게 된다.When the air pump 6 is operated, the air flows along the tube 5 and fed to the pressurization chamber 4, which is a space between the housing 3 and the infusion bag 2. Air is introduced into the pressurizing chamber 4, so that the pressure in the pressurizing chamber 4 becomes high.

가압실(4)의 공기는 그 내부에 있는 수액백(2)을 가압하게 되고, 그 압력으로 수액이 수액줄(1)로 송급되어 환자 등에게 주입된다. 주입될 때의 압력이 중요하므로, 압력센서(7)는 항상 그 압력을 모니터링하고, 실시간 계측된 압력은 제어장치(8)에서 설정치와 비교된다. 따라서 설정치의 압력을 위해 에어펌프(6)의 작동이 제어장치에 의해 제어됨으로써, 항상 일정한 압력이 가해져 일정한 양의 수액이 주입되게 된다.The air in the pressurizing chamber 4 pressurizes the liquid bag 2 inside the pressurizing chamber 4, and the liquid is fed to the liquid bag 1 by the pressure, and is injected into the patient or the like. Since the pressure at the time of injection is important, the pressure sensor 7 always monitors the pressure, and the real-time measured pressure is compared with the set value in the control device 8. [ Therefore, the operation of the air pump 6 is controlled by the control device for the pressure of the set value, so that a constant pressure is always applied and a certain amount of liquid is injected.

그리고 수액줄(1)에는 체크밸브(9)가 설치되어 있다. 이는 수액백(2)의 설치위치가 과도하게 높거나, 수액백(2)이 외부의 이상 압력에 의해 수축될 경우, 수액이 에어펌프(6) 쪽으로 역류되는 것을 방지하는 역할을 한다.A check valve (9) is provided in the liquid receiver (1). This prevents the liquid from flowing back toward the air pump 6 when the liquid bag 2 is installed at an excessively high position or when the liquid bag 2 is contracted by external abnormal pressure.

또한 가압실(4)에는 압력계(10)가 설치될 수 있는데, 이 경우에는 제어장치(8)와는 별도로 환자, 간호사 등이 쉽게 육안으로 측정할 수 있어 자동 장치를 보완하여 더욱더 신뢰성 있는 수액의 압력 관리가 가능하게 된다.In addition, the pressure gauge 10 can be installed in the pressurizing chamber 4. In this case, a patient, a nurse or the like can easily measure with the naked eye separately from the control device 8, so that the automatic device is supplemented, Management becomes possible.

상기와 같은 제어장치(8)에 의한 설치된 수준의 수액 공급압력이 유지됨으로써, 항상 일정한 양의 수액이 공급되어 의도한 대로의 치료와 시술이 가능하게 된다.
By maintaining the liquid supply pressure at the level set by the control device 8 as described above, a constant amount of liquid is always supplied, and treatment and operation can be performed as intended.
