Field of the Invention The present invention relates to a medical suction apparatus, and in particular, to maintain a constant pressure in an impeller chamber at all times so as to randomize a plurality of medical suctions coupled to a suction inlet coupled to an impeller chamber. It relates to a suction device to ensure that the suction power of each suction is always maintained even when used.

일반적으로 의료용 석션장치는 임펠러 챔버의 상부에 결합된 모터와, 임펠러 챔버의 하부에 각기 결합된 필터 하우징(filter housing), 세퍼레이트 드레인 튜브(separate drain tube), 공기 배출구, 및 하수 배출구로 구성되며, 석션 흡입구에 석션 흡입호스를 통해 복수개의 석션이 연결된다. 이때 석션 흡입구는 세퍼레이트 드레인 튜브의 외측에 구비된다.In general, the medical suction device is composed of a motor coupled to the upper portion of the impeller chamber, a filter housing, a separate drain tube, an air outlet, and a sewage outlet respectively coupled to the lower portion of the impeller chamber. A plurality of suctions are connected to a suction inlet through a suction suction hose. At this time, the suction inlet is provided on the outside of the separate drain tube.

이와 같은 일반적인 의료용 석션장치에 있어서, 임펠러 챔버의 내부는 모터의 회전에 의해 진공 상태가 유지된다.In such a general medical suction device, the interior of the impeller chamber is maintained in a vacuum state by the rotation of the motor.

도 7은 도 1에 도시된 의료용 석션장치의 석션 흡입구(26)에 복수개의 석션(54)이 결합되는 예를 나타낸 도면으로, 석션 흡입구(26), 조인트 커넥터(50), 석션 흡입호스(52), 석션(54), 솔레노이드 밸브(56), 및 분기호스(58)로 구성된다.FIG. 7 is a view illustrating an example in which a plurality of suctions 54 are coupled to a suction suction port 26 of the medical suction device shown in FIG. 1, and a suction suction hole 26, a joint connector 50, and a suction suction hose 52 are illustrated. ), Suction 54, solenoid valve 56, and branch hose 58.

도 8은 도 1에 도시된 의료용 석션장치의 압력 송신기(16) 및 도 7에 도시된 밸브(56)로부터 제공되는 신호에 따라 인버터(28)가 모터(12)의 구동을 제어하는 예를 나타낸 블록도이다.FIG. 8 shows an example in which the inverter 28 controls the driving of the motor 12 according to signals provided from the pressure transmitter 16 of the medical suction device shown in FIG. 1 and the valve 56 shown in FIG. It is a block diagram.

먼저 임펠러 챔버(10)는 상부에 결합된 모터(12)의 구동에 의해 내부가 진공 상태로 유지된다. 이때 모터(12)의 회전 속력이 빠를수록 임펠러 챔버(10) 내부의 진공도가 커진다.First, the impeller chamber 10 is maintained in a vacuum state by the driving of the motor 12 coupled to the upper portion. At this time, the faster the rotational speed of the motor 12, the greater the degree of vacuum inside the impeller chamber 10.

석션 흡입구(26), 필터 하우징(20), 하수 배출구(30), 및 공기 배출구(34)는 임펠러 챔버(10)에 각기 결합된다. 이때 석션 흡입구(26)는 세퍼레이트 드레인 튜브(24)를 통해 임펠러 챔버(10)에 결합된다.The suction inlet 26, the filter housing 20, the sewage outlet 30, and the air outlet 34 are respectively coupled to the impeller chamber 10. The suction inlet 26 is then coupled to the impeller chamber 10 via a separate drain tube 24.

복수개 예로, 5개의 석션(54)은 석션 흡입구(26)에 호스(58, 52) 및 조인트 커넥터(50)를 통해 연결된다. 이때 각 석션(54)은 일반적으로 각 체어(도면 중에 도시되지 않음)마다 구비된 석션 홀더(도면 중에 도시되지 않음)에 보관되고 각 석션(54)에 구비된 각 밸브(56)는 석션(54)을 석션 홀더에서 이탈 시 자동으로 온(on)될 수 있다. 상기 체어는 치과 등에서 사용되는 의료용 체어일 수 있다.In a plurality of examples, five suctions 54 are connected to the suction inlet 26 via hoses 58 and 52 and joint connector 50. At this time, each suction 54 is generally stored in a suction holder (not shown in the figure) provided for each chair (not shown in the figure), and each valve 56 provided in each suction 54 is a suction 54. ) Can be turned on automatically when it is removed from the suction holder. The chair may be a medical chair used in dentistry and the like.

임펠러 챔버(10)는 복수개의 석션(54)으로부터 랜덤하게 흡입되는 하수를 호스(58, 52), 조인트 커넥터(50), 셕션 흡입구(26), 및 세퍼레이트 드레인 튜브(24)를 통해 흡입하여 불순물과 물로 분리해서 불순물은 필터 하우징(20)으로 보내고 물은 하수 배출구(30)를 통해 배출하며, 공기는 공기 배출구(34)를 통해 배출시킨다.The impeller chamber 10 sucks the sewage that is randomly sucked from the plurality of suctions 54 through the hoses 58 and 52, the joint connector 50, the suction inlet 26, and the separate drain tube 24 to remove impurities. The impurities are separated into the water and the water is sent to the filter housing 20, and the water is discharged through the sewage outlet 30, and the air is discharged through the air outlet 34.

이와 같이 임펠러 챔버(10)가 하수를 불순물과 물로 분리해서 각기 배출시키는 것은 일반적으로 잘 알려진 것으로, 그 상세한 설명은 생략하기로 한다.As such, it is generally well known that the impeller chamber 10 separates sewage into impurities and water, respectively, and a detailed description thereof will be omitted.

압력 송신기(16)는 임펠러 챔버(10)의 일 측에 관통체결되어 임펠러 챔버(10) 내의 압력을 측정해서 임펠러 챔버(10) 내의 압력 신호를 인버터(28)로 송신한다.The pressure transmitter 16 penetrates through one side of the impeller chamber 10 to measure the pressure in the impeller chamber 10 and transmits a pressure signal in the impeller chamber 10 to the inverter 28.

인버터(28)는 압력 송신기(16)로부터 송신되는 압력 신호에 따라 모터(12)의 구동을 제어해서 임펠러 챔버(10) 내의 압력을 항상 일정한 수준으로 유지시킨다. 이때 인버터(28)는 복수개의 석션(54)에 각기 구비된 복수개의 밸브(56) 중 어느 하나라도 온(on)될 경우 구동하여 모터(12)를 구동시킴으로써 임펠러 챔버(10)의 내부가 진공 상태를 유지하도록 한다.The inverter 28 controls the driving of the motor 12 according to the pressure signal transmitted from the pressure transmitter 16 to keep the pressure in the impeller chamber 10 at a constant level at all times. In this case, the inverter 28 is driven when any one of the plurality of valves 56 provided in the plurality of suctions 54 is turned on to drive the motor 12 so that the interior of the impeller chamber 10 is vacuumed. Keep your status.

바이패스 스위치(60)는 사용자에 의해 수동으로 조작되어 인버터(28)로 바이패스 신호를 전송해서 인버터(28)가 모터(12)를 특정 회전력 예로, 65Hz의 고정 주파수로 구동시키도록 한다. 이때 바이패스 스위치(60)는 압력 송신기(16) 등이 고장날 경우 비상용으로 사용되는 것이 좋다.The bypass switch 60 is manually operated by the user to transmit a bypass signal to the inverter 28 so that the inverter 28 drives the motor 12 at a specific rotational force, for example, a fixed frequency of 65 Hz. In this case, the bypass switch 60 may be used for emergency when the pressure transmitter 16 is broken.

이와 같은 본 발명은 임펠러 챔버(10) 내의 압력을 항상 일정하게 유지시켜 임펠러 챔버(10)에 결합된 석션 흡입구(26)에 결합된 복수개의 의료용 석션(54)을 랜덤하게 사용할 경우에도 각 석션(54)의 흡입력이 항상 정상적으로 유지되도록 하기 때문에, 석션의 사용 수에 상관없이 모든 석션이 항상 최적화되는 장점이 있다.The present invention maintains a constant pressure in the impeller chamber 10 at all times, even when randomly using a plurality of medical suctions 54 coupled to the suction inlet 26 coupled to the impeller chamber 10. Since the suction force of 54) is always maintained normally, all suctions are always optimized regardless of the number of suctions used.

또한, 사용되는 석션의 수가 적을수록 모터(12)에 과부하가 걸리지 않게 되기 때문에, 모터(12)의 수명이 길어지고 전력소비도 작아진다.In addition, as the number of suctions used is smaller, the motor 12 is not overloaded, so the life of the motor 12 is longer and the power consumption is smaller.

이상에서 본 발명에 대한 기술사상을 첨부도면과 함께 서술하였지만 이는 본 발명의 바람직한 실시 예를 예시적으로 설명한 것이지 본 발명을 한정하는 것은 아니다. 또한, 이 기술분야의 통상의 지식을 가진 자라면 누구나 본 발명의 기술사상의 범주를 이탈하지 않는 범위 내에서 다양한 변형 및 모방이 가능함은 명백한 사실이다.Although the technical spirit of the present invention has been described above with reference to the accompanying drawings, this is intended to describe exemplary embodiments of the present invention by way of example and not to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
