The present invention relates to a cylinder back pressure protection device to be used in the water injection nozzle for Lipolytic, more specifically, the skin layer of fat is inserted into the supply pipe is connected to the nozzle head to be formed to spray the liquid and with the nozzle head is integrally sikidoe forming a pump body which can supply the liquid to the interior of the pump body is a ceramic piseutonwa the pump to protect the seals and the pump body interior to maintain the confidentiality of the fixing groove, and the piston and the pump body which houses a piston for compression and the space portion to discharge the liquid that flows inside the body to the outside, consists of an air outlet for removing the back pressure generated by the piston operation, the space portion inside compresses the ball by the pressure produced by the ceramic piston operation and built-in spring can be contracted by supplying or blocking the liquid flowing also, of course, can be removed to back pressure which is generated inside the pump body as well as by the pressure generated by the up, down movement of the space of the piston spraying the drug and, on the piston movement during the packing and piston ball and the water injection nozzle for Lipolytic consisting drug is introduced by the spring is blocked and the generated back pressure to exhaust equipped with a back pressure that occurs between the ceramic inside the piston It relates to a back-pressure protection device of a ceramic piston and cylinder is used.Removing the fat tissue pumps, pump adipose tissue ye wanyong본 발명은 체지방 분해용 물분사 노즐에 사용되는 실린더 역압 방지장치에 관한 것으로서, 보다 상세하게는 피부 지방층 내부에 삽입되어 액체를 분사할 수 있도록 형성되는 노즐 헤드와 상기 노즐 헤드와 일체로 연결되는 공급관의 내부에 액체를 공급할 수 있는 펌프 몸체를 형성시키되, 상기 펌프 몸체는 압축용 피스톤을 수용하는 고정홈과, 피스톤과 펌프 몸체의 기밀을 유지시키는 패킹과, 펌프 몸체 내부를 보호하는 세라믹 피스톤와, 펌프 몸체 내부에 유입되는 액체를 외부로 배출하는 공간부와, 피스톤 작동에 의해 발생되는 역압을 제거하기 위한 에어배출구로 구성되며, 상기 공간부 내부는 세라믹 피스톤 작동에 의해 발생되는 압력에 의해 볼을 압축 및 수축할 수 있는 스프링을 내장하여 유입되는 액체를 공급 또는 차단함은 물
