Description

실험동물 사육용 케이지의 급기용 이중 안전밸브{THE AIR SUPPLYING DOUBLE SAFETY VALVE FOR LAB ANIMAL ISOLATION CAGE}Double safety valve for supply of cage for laboratory animal breeding

본 발명은 실험동물 사육용 케이지의 급기용 이중안전밸브에 관한 것이다.The present invention relates to a double safety valve for supply air supply cages for laboratory animals.

마우스, 랫트 등의 실험동물을 이용하여 약효나 독성 등의 생체실험(In vivo)을 하고 있으며, 실험동물은 케이지에서 적정온도와 무균상태로 사료와 물 및 공기 등을 공급 받으면서 사육된다.Experimental animals such as mice and rats are used for in vivo experiments, such as drug efficacy and toxicity. Experimental animals are reared in the cage while being fed with feed, water, and air at appropriate temperatures and aseptic conditions.

실험동물을 효율적으로 사육하기 위한 케이지의 연구 개발이 진행되고 있다.Research and development of cages for efficiently raising experimental animals is in progress.

종래에는, 실험동물 사육용 케이지를 선반대에 밀어 넣으면, 선반대에 고정되어있는 무균 공기 급기구의 노즐이 케이지에 부착된 밸브를 밀게되어 밸브가 열려 공기가 케이지내로 공급되고, 케이지를 빼내면 밸브가 닫치도록 구성하여, 외부공기와 내부공기를 차단하여 오염을 방지하도록 하였다.Conventionally, when the cage for laboratory animal breeding is pushed into the shelf, the nozzle of the sterile air supply unit fixed to the shelf pushes the valve attached to the cage, the valve opens, the air is supplied into the cage, and the cage is removed. The valve was configured to close, blocking external and internal air to prevent contamination.

그러나, 이러한 케이지 내에서 실험 동물을 사육하게 되면, 실험동물의 배설물이 생기고 깔집을 바닥에 깔게 됨으로써 발생되는 갖가지 분진 및 작은 깔집 조각들이 깔집 교체 시나 케이지 청소 또는 세척 시에 밸브의 구멍으로 들어가고 축적되어 밸브의 작동이 불량해지고 밀착이 이루어지지 않아 케이지 내의 공기가 오염되는 문제점이 있었다.However, when breeding test animals in such cages, various dust and small pieces of rugs generated by the excretion of the test animals and by spreading the rugs on the floor enter and accumulate in the holes of the valves when the rug is replaced or the cage is cleaned or cleaned. There was a problem that the operation of the valve is poor and the adhesion is not made, the air in the cage is polluted.

본 발명은 상기와 같은 문제점을 해결하기 위하여, 두 개의 밸브로 구성되어 케이지 내부와 외부를 이중으로 차단하여 공기오염을 방지하고, 케이지 내부 쪽에 있는 깔집이나 부산물들이 밸브 내부로 들어가지 못하도록 하며, 세척 및 관리가 용이한 급기용 이중안전밸브를 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention consists of two valves to prevent the air pollution by double blocking the inside and the outside of the cage, so that the rug or by-products on the inside of the cage does not enter the inside of the valve, washing And to provide a double safety valve for the air supply easy to manage.

내부밸브(42)는, 접시형상으로 고정볼트(41)가 삽입되는 중앙부는 홀이 작아지며 돌출되어 있고, 바깥 동심원상에 공기를 통하게 하는 다수 개의 통기홀(42a)을 갖추고 있다.The inner valve 42 is provided with a plurality of vent holes 42a through which a central portion into which the fixing bolt 41 is inserted in a dish shape becomes smaller and protrudes, and allows air to flow on an outer concentric circle.

본 발명의 급기용 이중안전밸브를 조립하고 케이지의 상자(30)에 설치하는 방법은 다음과 같다.Assembling the double safety valve for the air supply of the present invention and installed in the box 30 of the cage is as follows.

밸브몸체(43)에 스프링(45)을 내장시키고, 그 위에 외부밸브(46)를 넣은 다음 고정슬리브(47)를 놓고 프레스로 압축하여 밸브몸체에 외부밸브를 장착시킨다.The spring body 45 is embedded in the valve body 43, the external valve 46 is put thereon, the fixed sleeve 47 is placed thereon, and the press is mounted in a press to mount the external valve on the valve body.

케이지의 상자(30)에 구멍을 뚫고 외부밸브가 장착된 밸브몸체를 상자에 밀어넣은 다음, 2 개의 고정핀(44a)으로 밸브몸체를 상자에 고정한다.Punch the box 30 of the cage and push the valve body equipped with an external valve into the box, and then secure the valve body to the box with two fixing pins (44a).

내부밸브(42)를 상자 안 쪽에서 밸브몸체에 대고 고정볼트(41)와 고정너트(48)로 조립하여 설치한다.Assemble the inner valve 42 to the valve body from the inside of the box by installing the fixing bolt 41 and the fixing nut 48.

도 3을 참조하여 본 발명의 급기용 이중안전밸브의 작동을 설명한다.Referring to Figure 3 will be described the operation of the double safety valve for air supply of the present invention.

도3의 A는 실험동물 사육용 케이지를 선반대에 밀어 넣기 전에 이중안전밸브가 닫힌 상태(A)를 나타낸 것이고, 도3의 B 는 케이지를 선반대에 밀어 넣어 이중안전밸브가 급기슬리브와 결합하여 열린상태를 나타낸 단면도이다.3A shows a state where the double safety valve is closed (A) before pushing the cage for experiment animal breeding into the shelf, and FIG. 3B shows the double safety valve coupled with the air supply sleeve by pushing the cage into the shelf. Is a cross-sectional view showing an open state.

케이지를 선반대에 밀어 넣으면, 급기슬리브(61)가 이중안전밸브(40)를 감싸면서 에어노즐파이프(62)에 장착된 스프링B(64)에 연결된 실리콘봉(63)이 이중안전밸브의 후면에 압력을 가하게 된다.When the cage is pushed into the shelf, the air supply sleeve 61 surrounds the double safety valve 40 and the silicon rod 63 connected to the spring B 64 mounted on the air nozzle pipe 62 has the rear of the double safety valve. Pressure is applied.

압력을 받은 이중안전밸브의 스프링A가 압축되면서, 외부밸브가 밸브몸체 안으로 이동하여 외부밸브가 열리고, 외부밸브와 연결되어 있는 내부밸브(42) 또한 상자(30) 안으로 밀려들어가면서 내부밸브가 열리게 된다.As the spring A of the double safety valve under pressure is compressed, the outer valve moves into the valve body to open the outer valve, and the inner valve 42 connected to the outer valve is also pushed into the box 30 to open the inner valve. .

밸브가 열리면 공기공급관(60)에 부착되어 구성된 에어노즐파이프(62)를 통과한 무균 공기는 스프링B(64) 사이로 통과한 다음, 이중안전밸브의 외부밸브와 내부밸브를 통하여 상자(30) 안으로 유입된다.When the valve is opened, the sterile air passing through the air nozzle pipe 62 attached to the air supply pipe 60 passes between the spring B 64 and then into the box 30 through the outer valve and the inner valve of the double safety valve. Inflow.

한편, 에어노즐파이프(62) 앞쪽에 자바라형의 급기슬리브(61)가 설치되어 있어, 외부 공기는 급기슬리브 내부로 들어오지 못하게 하고, 내부 공기의 압력이 과다하게 높을 때는 공기를 밖으로 빠져나가 새도록 하여 과다한 압력을 방지하고 케이지에 급기되는 공기량을 일정하게 유지시켜 준다.On the other hand, a bellows type air supply sleeve 61 is provided in front of the air nozzle pipe 62, so that the outside air does not enter the air supply sleeve, and when the pressure of the internal air is excessively high, the air escapes to the outside. It prevents excessive pressure and keeps the air supply to the cage constant.

실험동물 사육용 케이지를 선반대에서 빼내면, 이중안전밸브가 급기슬리부(61)에서 떨어지고, 이중안전밸브는 스프링A(45)의 복원력에 의해 원래의 닫힌 상태로 돌아온다.When the cage for experiment animal breeding is removed from the shelf, the double safety valve falls from the air supply sling part 61, and the double safety valve returns to its original closed state by the restoring force of the spring A 45.

본 발명에 의해, 실험동물 사육용 케이지에 무균 공기를 고르게 공급하고, 케이지 내부와 외부를 이중으로 차단하여 오염을 방지하고, 이중안전밸브가 닫힌 상태에서는 케이지내의 깔집이나 부산물들이 밸브 내부로 들어가지 못하며, 세척 등의 관리에 용이한, 실험동물 사육용 케이지의 급기용 이중안전밸브가 제공된다.According to the present invention, evenly supplying sterile air to the cage for experiment animal breeding, preventing the contamination by double blocking the inside and the outside of the cage, and when the double safety valve is closed, the rug or by-products in the cage do not enter the inside of the valve. There is provided a double safety valve for supplying the cage for laboratory animal breeding, which is not easy to manage such as washing.
