Description

이중 냉각 방식의 극저온 치료기{CRYOGENIC THERAPEUTIC DEVICE HAVING DOUBLE COOLING SYSTEM}TECHNICAL FIELD [0001] The present invention relates to a dual-cooling type cryo-therapy device,

본 발명은 극저온 치료기에 관한 것으로서, 보다 상세하게는 펠티어 소자를 이용한 냉각과 볼텍스 튜브를 이용한 냉각의 이중 냉각방식을 이용하여 기체를 냉각하되 냉각기체로 공기를 사용하는 극저온 치료기에 관한 것이다.The present invention relates to a cryogenic treatment apparatus, and more particularly, to a cryogenic treatment apparatus using air as a cooling body while cooling a gas by using a dual cooling method of cooling using a Peltier element and cooling using a vortex tube.

극저온 치료기는, 극저온의 냉각 기체를 피치료자의 환부에 분사함으로써 통증의 완화, 부종 경감 등의 치료에 사용되는 장치이다. 즉, 환부를 낮은 온도로 유지하여 통증의 완화, 부종의 경감 등에 사용하는 기기로서, 급격한 온도 변화의 열 충격에 의해 활성화된 피부인 경수 요체는 대뇌로 경계신호를 보내고 대뇌는 자율신경반사 시스템을 통해 즉각 반응, 자가치유기능을 통해 치료하는 원리의 의료용 저온기이다.The cryogenic treatment apparatus is a device used for treatment such as alleviation of pain and alleviation of swelling by spraying a cooling gas at a cryogenic temperature to a lesion portion of a therapist. In other words, it is a device used for relieving pain and relieving edema by keeping the affected part at a low temperature. It is a device that is activated by the thermal shock of rapid temperature change, and sends the boundary signal to the cerebrum. It is a medical cryocooler that treats through immediate reaction and self-healing function.

도 1은 종래의 극저온 치료기의 외관을 예시적으로 도시한 것이며, 도 2는 종래 극저온 치료기의 구성을 나타낸 도면이다. 종래의 극저온 치료기는, 냉각 기체 생성부와 장치 전반을 제어하는 제어부를 포함하는 본체와 냉각 기체를 환부에 분사하는 핸드 피스로 구성된다. 핸드 피스는 케이블에 의해 본체의 냉각 기체 생성부와 연결되어 이로부터 전달되는 냉각 기체를 조작자가 손에 쥐고 환부에 분사함으로써 극저온 치료를 수행하게 된다.FIG. 1 is an illustration of an appearance of a conventional cryo-therapy apparatus, and FIG. 2 is a diagram showing a configuration of a conventional cryo-therapy apparatus. A conventional cryogenic therapy apparatus comprises a main body including a cooling gas generator and a control unit for controlling the entire apparatus, and a handpiece for spraying the cooling gas onto the lesion. The handpiece is connected to the cooling gas generator of the main body by a cable, and the cooling gas delivered from the handpiece is held by the operator in the hand and sprayed on the affected area to perform the cryogenic treatment.

이와 같은 극저온 치료기에 의해 극저온 치료를 수행할 때 피부에 냉각 기체를 분사하여 피부의 온도가 내려가게 하는 것으로, 지속적으로 냉각 기체를 공급할 수 있어야 한다. 기존의 극저온 치료기에는 치료용 냉각기체로 질소 또는 이산화탄소를 사용하였고, 이들 냉각 기체를 탱크에 저장한 후 필요시 환부로 분사하도록 하였다. 그런데, 탱크 내에 저장된 기체를 모두 소모한 경우에는 저장된 탱크 자체를 교체하여 사용하여야 하였다. 즉, 기존의 냉각 치료기가 질소, 이산화탄소 등의 냉각기체를 저장한 탱크를 사용하여 치료를 하고 냉각 기체 소모에 따라 주기적으로 탱크를 교체해야만 하였다. 그러므로 종래의 극저온 치료기에서는 냉각 기체 저장용 탱크 유지 및 교체 등에 과다한 비용과 어려움이 있었다. When cryogenic treatment is performed by such a cryotherapy apparatus, cooling gas is sprayed to the skin to lower the temperature of the skin, so that it is necessary to continuously supply the cooling gas. Nitrogen or carbon dioxide was used as a treatment cooler in the conventional cryosurgical treatment apparatus, and these cool gas was stored in a tank and sprayed to the affected part when necessary. However, if the gas stored in the tank is exhausted, the stored tank itself must be replaced. In other words, the existing cooling system was treated with a tank storing cooling gas such as nitrogen and carbon dioxide, and the tank was periodically changed in accordance with the consumption of the cooling gas. Therefore, conventional cryo-therapy apparatus have had a great deal of cost and difficulty in maintenance and replacement of the cooling gas storage tank.

도 3는 본 발명의 일실시예에 의한 극저온 치료기의 구성을 나타낸 도면이다.도 4는 본 발명의 일실시예에 의한 극저온 치료기에 사용되는 케스케이드 펠티어 소자이다.[0001] The present invention relates to a cryocooler, and more particularly, to a cryocooler used in a cryogenic treatment apparatus according to an embodiment of the present invention.

도 3 및 도 4를 참조하면, 본 발명에 따른 극저온 치료기의 구성을 보면, 기체를 1차 냉각하여 탱크에 저장하고 환부에 분사시에 2차로 냉각하면서 분사하는 것이 특징이며, 냉각 기체가 보관된 탱크 교체과정을 없애기 위해 냉각 기체로는 대기중의 공기를 사용하는 것이 특징이며, 이를 위해 기체를 1차 냉각하는 제1냉각장치(100)와 2차 냉각하는 제2냉각장치(400)를 가진다.Referring to FIGS. 3 and 4, the cryogenic treatment apparatus according to the present invention is characterized in that the gas is first cooled and stored in a tank, and injected into the affected part while being cooled secondarily. In order to eliminate the tank replacement process, air is used as a cooling gas. To this end, a first cooling device 100 for cooling the gas firstly and a second cooling device 400 for cooling the gas are provided .

본 발명은, 1차냉각을 위해 외부 공기(a1)를 제1냉각장치(100)로 유입하되 필터(50)를 거쳐서 이물질을 제거한 공기(a2)를 유입한다. 상기 제1냉각장치(100)는, 유입된 공기와 열교환 과정을 통해 공기를 냉각시키는 열교환기(110)와, 상기 열교환기에 부착되어 열교환을 통해 기체를 냉각하는 캐스캐이드 펠티어 소자(120)와, 상기 캐스캐이드 펠티어 소자에 접하여 열을 전달 받아 방출하는 방열판(130)과, 상기 방열판의 열을 외부로 방출하는 냉각팬(140)을 포함한다. 상기 캐스캐이드 펠티어 소자(120)는 다수 개의 펠티어 소자(N1,N2...NN)가 접하여 이루어진다.In the present invention, external air (a1) flows into the first cooling device (100) for primary cooling, and air (a2) from which foreign matters are removed through the filter (50) flows. The first cooling device 100 includes a heat exchanger 110 for cooling the air through heat exchange with the introduced air, a cascade Peltier element 120 attached to the heat exchanger for cooling the gas through heat exchange, A heat sink 130 for receiving and discharging heat in contact with the cascade Peltier element, and a cooling fan 140 for discharging the heat of the heat sink to the outside. The cascade Peltier element 120 is formed by contacting a plurality of Peltier elements N1, N2, ..., NN.

펠티어(열전모듈, Peltier)소자는 N형 반도체소자 와 P형 반도체소자로 내부를 구성하고, 그 양측면에는 접합금속판을 형성하여 이루어진 것으로, 펠티어소자에 전원을 공급하게 되면, 양 접합금속판 중 일측면은 흡열반응이 일어나게 되고, 타측면은 흡열한 열을 방열하는 방열반응이 일어나게 되는 바, 이러한 원리를 가진 펠티어소자의 흡열면에 열교환부 를 형성하게 되면 흡열면의 주위 기온을 냉각시킬 수 있게 되고, 방열면에 열교환부를 형성하게 되면, 주위 온도을 상승시킬 수 있게 된다. 본 발명의 케스케이드 펠티어 소자(120)는 이러한 각각의 펠티어소자를 복수 개를 서로 연결한 것이며, 펠티어 소자의 흡열면을 상기 열교환기(110) 측에 접하게 하여 유입된 공기의 냉각에 이용한 것이다.The Peltier element comprises an N-type semiconductor element and a P-type semiconductor element. The Peltier elements are formed on both sides thereof with a bonding metal plate. When power is supplied to the Peltier element, The endothermic reaction occurs and the other side radiates a heat radiating reaction to dissipate the heat that is endothermic. When the heat exchanging part is formed on the heat absorbing surface of the Peltier element having such a principle, the ambient temperature of the heat absorbing surface can be cooled , And if the heat exchanging portion is formed on the heat radiating surface, the ambient temperature can be raised. The cascade Peltier element 120 of the present invention connects a plurality of such Peltier elements to each other and uses the heat absorbing surface of the Peltier element to contact the heat exchanger 110 side to cool the introduced air.

상기 제1냉각장치(100)에서 1차로 냉각된 공기(a3)는 압축기(200)에서 압축된 후 압축된 공기(a4)가 저장탱크(300)에 저장된다. 그리고, 치료가 필요한 경우에 저장탱크에 저장된 공기가 배출되면서 제2냉각장치(400)에서 2차냉각 과정을 거치게 된다. 제2냉각장치(400)는, 상기 저장탱크에서 배출되는 압축 공기(a5)를 유입한 후, 볼텍스 튜브를 이용하여 2차 냉각하게 된다. 그리고, 상기 볼텍스 튜브에서 2차 냉각되어 토출되는 기체는 핸드피스(500)를 이용하여 환자의 환부에 투사하게 된다.The compressed air a4 after being compressed by the compressor 200 is stored in the storage tank 300. The compressed air a4 is firstly cooled in the first cooling device 100, When the treatment is required, the air stored in the storage tank is discharged, and the second cooling process is performed in the second cooling unit 400. After the compressed air a5 discharged from the storage tank flows into the second cooling unit 400, the second cooling unit 400 is cooled by using a vortex tube. The gas that is secondarily cooled and discharged from the vortex tube is projected onto the affected part of the patient using the handpiece 500.

도 5는 본 발명의 일실시예에 의한 극저온 치료기의 제2차냉각장치인 볼텍스 튜브의 단면 모습이다5 is a cross-sectional view of a vortex tube which is a second cooling device of a cryogenic treatment apparatus according to an embodiment of the present invention

상기 제2차냉각장치(400)인 볼텍스 튜브는 저장탱크에서 나온 고압의 공기(a5)가 와류실로 유입되면 외곽측에서 나선 회전하는 고온기체와 내측에서 나선 회전하는 저온기체로 분리되는 원리를 이용한 것이다. 볼텍스 튜브의 유입부(420)를 통해 상기 저장탱크(300)에서 압축되어 있던 기체가 유입되고, 유입된 기체는 볼텍스 튜브 몸체(410) 내부의 외곽측에서 나선 회전하는 고온기체(a6)와 내측에서 나선 회전하는 저온기체(a7)로 분리된다. 그리고, 고온기체와 저온기체는 각각 고온배출부(430)와 저온배출부(440)를 통해 외부로 배출된다. 상기 고온배출부(430)에는 원뿔 형상의 제어플러그(435)가 구비되어 있어서 고온배출부에서 배출되는 고온기체의 양과 저온배출부에서 배출되는 기체의 양을 조절할 수 있다. The vortex tube, which is the secondary cooling device 400, uses a principle in which, when high pressure air a5 from the storage tank flows into the swirl chamber, it is separated into a hot gas rotating spirally at the outer side and a cold gas rotating spirally at the inner side will be. The gas compressed in the storage tank 300 flows through the inlet 420 of the vortex tube, and the introduced gas flows into the vortex tube body 410 through the high temperature gas a6 spirally rotating on the outer side inside the vortex tube body 410, (A7) rotating in a spiral manner. The high-temperature gas and the low-temperature gas are discharged to the outside through the high-temperature discharge unit 430 and the low-temperature discharge unit 440, respectively. A control plug 435 having a conical shape is provided in the high temperature discharge part 430 so that the amount of the high temperature gas discharged from the high temperature discharge part and the amount of the gas discharged from the low temperature discharge part can be adjusted.

볼텍스 튜브(vortex tube)는 압축된 기체를 뜨거운 흐름과 차가운 흐름으로 분리시키는 것으로 뜨거운 부분의 온도는 200°C까지 올라가고 차가운 쪽 온도는 -50°C까지 떨어뜨릴 수 있다. 또한 가동부(moving part)가 없는 것이 특징이다. 압축된 공기가 와류실(swirl chamber)을 향해 분출되면 빠른 속도로 가속되며 회전한다. 튜브 끝에 있는 원뿔형 노즐 때문에 튜브 바깥에서 회전하던 기체만 밖으로 외부로 빠져 나가고, 빠져나가지 못한 나머지 기체는, 바깥 소용돌이(vortex) 안쪽에서, 반대 방향으로 되돌아가는 힘을 받아 소용돌이를 일으키며 되돌아가게 되는데, 본 발명은 이러한 볼텍스 튜브의 원리를 이용한 것이다.A vortex tube separates the compressed gas into hot and cold streams, where the temperature of the hot section can rise to 200 ° C and the temperature of the cold section can drop to -50 ° C. It also features no moving parts. When the compressed air is blown toward the swirl chamber, it accelerates and rotates at a high speed. Because of the conical nozzle at the end of the tube, only the gas that has been rotating outside the tube exits out of the tube, and the remaining gas, which has not escaped, returns from the inside of the outer vortex, causing the vortex to return in the opposite direction, The invention is based on the principle of this vortex tube.

본 발명은 위에서 설명한 바와 같이, 냉각 기체로 공기를 사용하는 것이 특징이며, 전자 냉각에 사용되는 펠티어 소자를 이용하여 1차 냉각을 하고 볼텍스 튜브를 이용하여 2차 냉각을 하도록 하는 것이 특징이다. 1차 냉각에서는 펠티어 소자를 제어하여 온도를 최대 -80℃까지 냉각한다. 1차 냉각된 공기는 압축기를 거쳐 저장탱크에 보관되었다 사용할 때 출력 밸브를 개방하여 볼텍스 튜브에 냉각된 공기를 공급한다. 볼텍스 튜브를 거친 공기는 재차 냉각되어 1차 냉각된 공기보다 더 낮은 온도를 가지게 되며 볼텍스 튜브의 설정에 따라 달라질 수 있다. 2차 냉각된 공기는 토출 제어용 레버가 달린 핸드피스를 통해 환부에 투사된다. 1차 냉각은 시술하지 않을 때 적절한 시점에 실시하고 시술할 때는 2차 냉각을 한다. 이렇게 시스템을 구축하면 별도로 냉각기체를 교환할 필요가 없어 유지보수 및 탱크 교체에 따른 사용상의 불편함을 해소할 수 있다.As described above, the present invention is characterized in that air is used as a cooling gas, and the Peltier element used for electronic cooling is used for primary cooling and secondary cooling is performed using a vortex tube. In the primary cooling, the Peltier element is controlled to cool the temperature up to -80 ° C. The primary cooled air is stored in a storage tank via a compressor. When in use, open the output valve to supply cooled air to the vortex tube. The air passing through the vortex tube will be cooled again and will have a lower temperature than the primary cooled air and may vary depending on the configuration of the vortex tube. The secondary cooled air is projected onto the affected part through the handpiece with the discharge control lever. The primary cooling is performed at an appropriate time when not performed, and the secondary cooling is carried out when the operation is performed. When the system is constructed as described above, there is no need to replace the cooling gas separately, and it is possible to solve the inconvenience of use due to maintenance and tank replacement.
