Description

주사 수액 역류방지 장치{Preventive device of back flow for injection}Injection device backflow prevention device {Preventive device of back flow for injection}

본 발명은 링겔의 수액이 공급 중 역류하는 것을 방지하기 위한 수액역류방지 장치에 관한 것으로서, 좀 더 상세하게는 수액이 통과하는 호스의 중간에 역류방지 챔버를 형성하되, 상기 역류방지 챔버의 내부에 유통공이 다수 형성된 격벽을형성한 후 상기 격벽의 중앙에 좌우로 이동하는 판막을 형성함으로써, 링겔액병이나 색에 수납된 수액이나 약액을 환자의 체내에 주사할때 부주의로 인해 혈액이 역류될 경우 판막이 유통공을 차단하여 혈액이 역류되는 것을 방지하도록 한 것에 관한 것이다.The present invention relates to a fluid backflow prevention device for preventing backflow of a ring gel fluid during supply, and more particularly, to form a backflow prevention chamber in the middle of a hose through which the fluid flows, and inside the backflow prevention chamber. After forming a bulkhead formed with a large number of distribution holes to form a valve that moves to the left and right in the center of the partition, when the blood flows inadvertently when injecting a ring gel fluid or sap or drug solution stored in the color into the patient's body It is related to blocking the circulation hole to prevent the backflow of blood.

일반적으로 링겔액병이나 색에 수납된 수액이나 약액을 환자에게 투여할 때 비교적 장시간이 소요되므로 이로 인하여 투액과정중 환자가 이동하는 일이 많게 되는데 이동 중이거나 움직일때 부주의로 인하여 혈액이 역류하는 경우가 발생될 수 있어 세심한 주의와 배려가 요구된다.In general, it takes a relatively long time to administer a ring gel solution or a sap or medicine stored in a color to the patient. Therefore, the patient often moves during the infusion process, and the blood flows back due to carelessness during movement or movement. It can be generated and requires close attention and consideration.

따라서 이와같은 문제점을 제거하기 위하여 도 1과 같은 주사 수액 역류방지 장치가 있으나, 이는 수액의 투약이 종료되었을때 체내로 공기가 공급되는 것을 방지할 수는 있으나 수액의 투약중 부주의로 인하여 혈액이 역류될 경우 혈액의 역류를 완전하게 차단할 수가 없었다.Therefore, in order to eliminate such a problem, there is an injection fluid backflow prevention device as shown in Figure 1, which can prevent the air supply to the body when the fluid administration is finished, but the blood flow back due to inadvertent administration of the fluid Could not completely block backflow of blood.

즉, 종래의 주사수액 역류방지 장치는 도 2에 도시한 바와같이 링겔액병(1)에 삽입되는 삽입침(4)이 상부에 설치되고, 하부에 일정량의 수액이 수납되는 점적 챔버(3)가 형성되며, 상기 점적챔버(3)의 하단에 호스(5)가 설치되는 점적셋트(2)에 있어서, 상기 점적 챔버(3) 내부에 부표(6)를 내장시킨 구조로 되어 있었다.That is, in the conventional injection fluid backflow prevention device, as shown in FIG. 2, an insertion needle 4 inserted into the ring gel fluid bottle 1 is installed at an upper portion thereof, and a drop chamber 3 in which a predetermined amount of fluid is stored is provided at the lower portion thereof. In the drop set 2 having the hose 5 installed at the lower end of the drop chamber 3, the buoy 6 is built in the drop chamber 3.

따라서 환자에게 공급되는 수액의 투약이 종료되면 부표(6)가 하부로 하강하여 호스(5)의 입구를 차단시켜 공기가 체내로 유입되는 것을 방지할 수 는 있으나 역류되는 압력이 작거나 점적셋트(2)가 옆으로 기울거나 반대로 뒤집혀져 있을 경우에는 부표(6)가 점적챔버(3)의 입구를 막지 못하여 혈액이 역류하는 것을 방지할수가 없었다.Therefore, when the dosing of the fluid supplied to the patient is finished, the buoy 6 is lowered to block the inlet of the hose 5 to prevent air from entering the body, but the backflow pressure is small or a drop set ( When 2) is inclined sideways or reversed, the buoy 6 could not block the entrance of the drip chamber 3, preventing blood from flowing back.

이와 같은 문제점을 제거하기 위하여 본 발명의 출원인이 출원한 특허출원 제2001-48705호가 있었다.In order to eliminate this problem, there is a patent application No. 2001-48705 filed by the applicant of the present invention.

그 중 도 7에 도시된 역류방지장치는 격벽에 판형 판막을 고정하여 좌우의 판막이 이동하여 혈액이 역류되는 것을 방지하도록 하고 있으나, 이는 판막의 좌우 이동이 미세하게 이루어 지도록 하기 위해서는 판막의 재질이나 두께 조절을 적절하게 하여야만 하였기 때문에 제작에 어려움이 있었고, 아주 미세한 혈액의 역류에 신속하게 작동하지 않는 문제점이 있었다.Among them, the backflow prevention device shown in FIG. 7 fixes the plate-shaped valve to the partition wall to prevent the left and right valves from moving and prevents the blood from flowing backwards. It was difficult to manufacture because it had to adjust the thickness properly, there was a problem that does not work quickly in the backflow of very fine blood.

따라서 본 발명은 상기와 같은 제반 문제점을 제거하기 위하여 창출된 것으로서 수액이나 약액을 환자에게 투여 중 부주의 등으로 혈액이 역류할 경우 이를 즉시 차단함과 동시에 혈액의 역류가 미세한 경우에도 혈액의 역류를 방지할 수 있는 주사 수액 역류 방지 장치를 제공하는데 발명의 목적이 있다.Therefore, the present invention was created in order to eliminate the above problems, and if blood flows back due to carelessness during administration of a sap or a medicine to a patient, the blood is immediately blocked, and at the same time, the flow of blood is prevented even when the flow of blood is minute. SUMMARY OF THE INVENTION An object of the invention is to provide an injection fluid backflow prevention device that can be used.

도 2에 도시된 바와 같이 링겔액병(1)의 하부에 일정량의 수액이 수납되는 점적셋트(2)가 설치되며, 상기 점적셋트(2)의 하단에 호스(5)가 연결되고, 상기 호스(5)의 중간에 수액공급 조절장치(7)가 설치되며, 상기 호스(5)의 끝단에 주사바늘(8)이 연결된 수액 공급기 셋트에 있어서, 상기 호스(5)의 중간에 역류방지 챔버(10)를 형성하되, 상기 역류방지 챔버(10)의 내부에 유통공(12)이 다수 형성된 격벽(11)을 형성한 후 상기 격벽(11)의 중앙에 좌우로 이동하는 판막(14)을 형성한다.As shown in FIG. 2, a drop set 2 for storing a predetermined amount of sap is installed at a lower portion of the ring gel liquid bottle 1, and a hose 5 is connected to a lower end of the drop set 2, and the hose ( A fluid supply adjusting device 7 is installed in the middle of 5), and in the fluid feeder set in which the needle 8 is connected to the end of the hose 5, the backflow prevention chamber 10 is located in the middle of the hose 5. ) To form a partition wall 11 having a plurality of distribution holes 12 formed inside the backflow prevention chamber 10 and then moving left and right in the center of the partition wall 11. .

이때, 상기 격벽(11)의 중앙에는 안내공(13)을 형성하고, 상기 판막(14)의 일측 중앙에는 안내봉(15)을 돌출시키며, 상기 안내봉(15)의 끝단에는 스톱퍼(16)를 형성한 후 상기 안내공(13)에 안내봉(15)이 삽입되도록 하여 안내봉(15)이 안내공(13)을 따라 좌우로 이동되도록 하고, 상기 격벽(11)과 판막(14)을 원호형으로 형성하여 혈액이 역류할 경우 판막(14)에 걸리는 역류압이 증가하도록 한다.At this time, the guide hole 13 is formed in the center of the partition 11, the guide bar 15 protrudes in the center of one side of the valve 14, the stopper 16 at the end of the guide bar 15 After forming a guide rod 15 is inserted into the guide hole 13 so that the guide rod 15 is moved left and right along the guide hole 13, and the partition 11 and the valve 14 It is formed in an arc shape to increase the backflow pressure applied to the valve 14 when the blood flows back.

이상과 같이 구성된 본 발명은 수액이 정상적으로 공급될 경우에는 도 3에 도시된 바와 같이 판막(14)이 격벽(11)과 이격되어 유통공(12)을 열어 수액을 공급하다가 혈액이 역류하여 역압이 걸리게 되면, 판막(14)이 격벽(11) 쪽으로 이동되어 격벽(11)과 밀착되어 유통공(12)을 막게 되므로 혈액(수액)이 역류되는 것을 방지하게 된다.According to the present invention configured as described above, when the sap is normally supplied, the valve 14 is spaced apart from the partition 11 to open the distribution hole 12 to supply the sap, and the blood flows backward to reverse the pressure. When caught, the valve 14 is moved toward the partition 11 to be in close contact with the partition 11 to block the distribution hole 12, thereby preventing the back flow of blood (sap).

즉, 정상적으로 수액이 공급될 경우에는 도 3에 도시된 바와 같이 판막(14)이 수액의 압력으로 수액이 흐르는 방향으로 이동되어 유통공(12)을 열어 수액을인체로 공급한다.That is, when the sap is normally supplied, as shown in FIG. 3, the valve 14 is moved in the direction in which the sap flows at the pressure of the sap to open the distribution hole 12 to supply the sap to the human body.

그리고 어떤 문제점이 있어 수액(혈액)이 역류할 경우에는 도 5에 도시된 바와 같이 판막(14)의 반대쪽(원호형의 오목부)에 압력이 걸려 판막(14)을 격벽(11)쪽으로 밀어 판막(14)이 격벽(11)과 밀착되어 유통공(12)을 막게 되므로써 혈액이 링겔액병(1)쪽으로 역류하는 것을 방지하게 된다.In addition, when fluid (blood) flows back due to a certain problem, pressure is applied to the opposite side of the valve 14 (arc recess), as shown in FIG. 5, to push the valve 14 toward the partition wall 11. The 14 is in close contact with the partition 11 to block the flow hole 12, thereby preventing the blood from flowing back toward the ring gel liquid bottle 1.

이와같은 본 발명의 수액역류 방지챔버(10)는 점적셋트(2)와 주사바늘(8) 사이의 호스(5) 어느 한곳에 설치하여 실시할 수 있는 것으로 주사바늘(8)에 가깝게 설치하여 실시하는 것이 바람직하며, 격벽(11)을 챔버(10)가 아닌 호스(5)에 직접 형성하여 실시할 수도 있는 것이다.Such a liquid backflow prevention chamber 10 of the present invention can be installed in any one of the hoses 5 between the drop set 2 and the needle 8 to be installed close to the needle 8 It is preferable that the partition 11 be formed directly on the hose 5 instead of the chamber 10.

상기와 같은 본 발명은 링겔액병이나 색의 수액이나 약액이 정상적으로 공급되다가 환자의 체내로 부터 혈액이 역류되어 호스 내부로 역압이 걸릴 경우 판막이 압압되어 수액통로를 막게 되어 있어 미세한 압력에도 판막이 이동되므로 체내의 혈압이 역류되면 빠르게 통로를 폐쇄시켜 혈압이 역류되는 것을 방지할 수 있으며, 점적셋트가 옆으로 기울거나 반대로 뒤집어져 혈압이 역류할 경우에도 판막에 압력이 가해지므로 항상 혈압이 역류할 경우 이를 신속하게 차단시킬 수 있는 효과가 있는 것이다.In the present invention as described above, the ring gel fluid bottle or the colored sap or the drug solution is normally supplied, and when the blood flows back from the patient's body and the back pressure is applied to the inside of the hose, the valve is pressurized to block the fluid passage so that the valve moves even at a minute pressure. Therefore, when the body's blood pressure is reversed, the passage can be closed quickly to prevent the blood pressure from flowing back.When the blood pressure is reversed because the drop set is inclined sideways or reversed, the pressure is applied to the valve. It is effective to block this quickly.
