본 발명을 설명함에 있어서 관련된 공지기능에 대하여 이 분야의 기술자에게 자명한 사항으로서 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우에는 상세한 설명을 생략한다. In the description of the present invention, when it is determined that the subject matter of the present invention may be unnecessarily obscured as matters apparent to those skilled in the art with respect to known functions related to the present invention, a detailed description will be omitted.

도 1은 본 발명의 냉찜질팩의 바람직한 실시예를 나타내는 도면이다.1 is a view showing a preferred embodiment of the cold pack of the present invention.

도 1에서 알 수 있듯이, 본 발명의 냉찜질팩(100)은 냉찜질부(110), 단열부(120), 분리폴딩부(130), 온도표시부(160)를 포함할 수 있다.As can be seen from FIG. 1, the cold pack 100 of the present invention may include a cold pack 110, a heat insulation unit 120, a separation folding unit 130, and a temperature display unit 160.

냉찜질부(110)는 가려움증 또는 통증을 완화시키기는 동시에 저온화상을 방지하기 위해 소정의 냉찜질온도를 제공하는 상변화물질(Phase Change Materials: PCM)이 충전된다. 바람직한 실시예에서 상변화물질은 고체상태에서 7℃를 초과하는 것이 바람직하다. 7℃에서는 차가운 통증이 발생하기 때문이다.The cold pack 110 is filled with a phase change material (PCM) that provides a predetermined cold pack temperature to relieve itching or pain while preventing low-temperature burns. In a preferred embodiment, the phase change material preferably exceeds 7°C in a solid state. This is because cold pain occurs at 7℃.

바람직한 실시예에서 냉찜질부(110)는 제1냉각온도를 제공하는 제1상변화물질이 충전된 제1냉찜질부(111) 및 제1냉각온도보다 낮은 제2냉각온도를 제공하는 제2상변화물질이 충전된 제2냉찜질부(113)를 포함할 수 있다. 바람직한 실시예에서 제1냉찜질부(111)는 20℃의 냉찜질 온도를 제공하고, 제2냉찜질부(113)는 14℃의 냉찜질 온도를 제공할 수 있으나, 반드시 이에 한정되는 것은 아니다. 제2냉찜질부는 가려움증의 강도가 강할 경우에 사용한다. 제2냉찜질온도는 제1냉찜질온도 보다 낮기 때문에 보다 신속하게 가려움증을 완화시킬 수 있다. 제1냉찜질부는 가려움증의 강도가 약할 때 사용한다. 제1냉찜질온도는 제2냉찜질온도보나 높기 때문에 보다 안전하게 가려움증을 완화시킬 수 있다.In a preferred embodiment, the cold pack 110 includes a first cold pack 111 filled with a first phase change material providing a first cooling temperature, and a second phase change providing a second cooling temperature lower than the first cooling temperature. It may include a second cold pack unit 113 filled with a material. In a preferred embodiment, the first cold pack 111 may provide a cold pack temperature of 20°C, and the second cold pack 113 may provide a cold pack temperature of 14°C, but is not limited thereto. The second cold pack is used when the intensity of itching is strong. Since the second cold pack temperature is lower than the first cold pack temperature, itching can be relieved more quickly. The first cold pack is used when the intensity of itching is weak. Since the first cold pack temperature is higher than the second cold pack temperature, itching can be more safely relieved.

본 발명의 냉찜질팩(100)은 아토피 등 각종 피부염으로 유발되는 가려움증으로 고통받는 환자들의 가려움증을 언제 어디서나 편리하게 완화시킬 수 있는 휴대용 냉찜질팩이다. 본 발명은 반영구적으로 사용이 가능하여 경제적이며, 얼음이나 종래 냉찜질팩을 사용할 시 너무 차가워서 발생하는 세포괴사나 동상 등을 유발하는 단점을 완벽히 제거했다. The cold pack 100 of the present invention is a portable cold pack that can conveniently relieve itching of patients suffering from itching caused by various dermatitis such as atopy anytime, anywhere. The present invention is economical because it can be used semi-permanently, and completely eliminates the disadvantages that cause cell necrosis or frostbite caused by being too cold when using ice or a conventional cold pack.

최적의 냉찜질 온도를 구현하기 위해 화상전문 대학병원의 재활의학과와 함께 임상연구를 진행하였다. 그 결과 20℃의 온도로 가려움증을 완화시키는 효과가 있음을 확인하였다. 본 발명은 임상연구를 통해 입증된 20℃온도를 토대로, 통증의 강도에 따라 온도를 달리 적용하여 2단계 치료(14℃ 및 20℃)가 가능할 수 있도록 제품을 고안하였다. A clinical study was conducted with the Department of Rehabilitation Medicine at the University Hospital specialized in burns to realize the optimal cold compress temperature. As a result, it was confirmed that the temperature of 20 ℃ has the effect of alleviating itching. The present invention devised a product to enable two-stage treatment (14° C. and 20° C.) by applying different temperatures according to the intensity of pain, based on the 20°C temperature proven through clinical studies.

또한, 가려움증을 완화시키기 위해 냉찜질팩을 사용할 시 14℃의 온도와 20℃의 온도를 사용하는 최적의 사용시간에 대한 프로토콜을 정의하였다. 이를 통해 가려움으로 고통을 겪는 전체 인구의 20%에 달하는 환자들이 안전하고 효과적으로 본 발명을 이용할 수 있을 것으로 기대된다.In addition, when using a cold pack to relieve itching, a protocol for optimal use time using a temperature of 14°C and 20°C was defined. Through this, it is expected that patients, up to 20% of the total population suffering from itching, can safely and effectively use the present invention.

위 임상연구는 화상 후 소양증으로 고생하는 환자 중 항히스타민제와 가파 팬틴제 투여에도 난치를 보이는 23명을 대상으로 실시되었다. 통증 강도 1에서 5등급 중 최고 등급 5에 해당하는 환자들에게 하루 세 번씩 20분간 각 환부에 냉찜질팩(100)을 접촉시키는 치료요법을 4주간 실시한 결과 치료 이전과 비교했을 때 증상과 통증이 현격히 완화된 것이 환자 23명 전원에게 나타났다. The above clinical study was conducted on 23 patients who suffered from pruritus after burns and showed refractory treatment even with antihistamine and Gapapantin. Patients with the highest grade 5 out of grades 1 to 5 were treated with a cold pack (100) in contact with each affected area for 20 minutes three times a day for 4 weeks.As a result, symptoms and pain were markedly compared to before treatment. All 23 patients showed relief.

가려움증에 대한 수치등급척도(numerical rating scale: NRS)는 치료 전 9.37±1.47에서, 치료 2주 후 3.48±2.19, 치료 4주 후 2.78±2.13로 감소하는 것으로 나타났다. 비침습적 시술이나 약물 투여 없이 20℃냉찜질으로도 화상 후 가려움과 통증이 현격히 호전된다는 것을 밝혀낸 것이다.The numerical rating scale (NRS) for itching decreased from 9.37±1.47 before treatment, 3.48±2.19 after 2 weeks of treatment, and 2.78±2.13 after 4 weeks of treatment. It was found that the itching and pain after burns were remarkably improved even with a cold compress at 20℃ without non-invasive procedures or drug administration.

However, if the inclined portion 140 is formed as in the present invention, this can be alleviated. In addition, the inclined portion is formed to have a low thickness of an area adjacent to the separating and folding portion 130, which contributes to increase the adhesion to the skin curved in a circular shape such as the face, arms, and legs.

도 4는 본 발명의 통기부의 바람직한 실시예를 나타내는 도면이다.4 is a view showing a preferred embodiment of the ventilation unit of the present invention.

도 4에서 알 수 있듯이, 피부와 접촉하는 제1냉찜질부 및 제2냉찜질부의 전면에는 피부에 밀착시 공기 또는 물이 순환될 수 있도록 엠보싱 형태의 통로가 형성된 통기부(150)가 형성될 수 있다. 바람직한 실시예에 있어서, 제1냉찜질부 및 제2냉찜질부의 전면에 형성되는 통기부(150)는 벌집형태일 수 있다.As can be seen in FIG. 4, a vent 150 may be formed on the front surface of the first cold pack and the second cold pack in contact with the skin so that air or water can circulate when in close contact with the skin. . In a preferred embodiment, the ventilation portion 150 formed on the front surface of the first cold pack and the second cold pack may have a honeycomb shape.

냉찜질부가 피부에 밀착되면 피부 사이에 틈새가 없기 때문에 통기가 불가능하고, 이로 인해 피부면의 산소량이 감소하는 문제가 발생한다. 또한 결로현상으로 생긴 물이 피부에 머물게 되어 환부에 무리를 줄 수 있다. 그러나 본 발명과 같이 통기부(150)를 형성하면 공기순환은 물론 수분의 흐름이 원활하게 되는 효과가 있다.When the cold pack is in close contact with the skin, ventilation is impossible because there is no gap between the skin, and thus, the amount of oxygen on the skin surface decreases. In addition, water caused by condensation can stay on the skin, which can strain the affected area. However, when the ventilation unit 150 is formed as in the present invention, there is an effect that the flow of moisture as well as air circulation is smooth.
