병원은 업무와 관련된 상해가 증가하고 있는 유해한 환경으로 간주되고 있다. 병원 직원들은 생물학적, 화학적 및 물리적인 요인에 노출되어 직업성 질환에 이환(罹患)될 수 있다.Hospitals are considered a hazardous environment, where work-related injuries are on the rise. Hospital staff may be exposed to occupational diseases due to exposure to biological, chemical and physical factors.

이러한 질환에 감염되는 일반적이고 가장 흔한 전파경로는 환자의 오염된 혈액이 점막이나 상처에 접촉되거나, 주삿바늘 또는 환자에게 사용한 각종 날카로운 기구에 찔리는 사고에 의한 것이다. 이런 상해는 병원 종사자들에게 매우 심각하고 치명적인 질병이 전파될 수 있는 직업적인 잠재적 위험을 안고 있다.The most common path of transmission of these diseases is due to accidents in which the patient's contaminated blood contacts the mucous membranes or wounds, or the needle or other sharp instruments used in the patient. These injuries pose a potential occupational risk for the transmission of very serious and fatal diseases to hospital workers.

주삿바늘에 의한 상해는 출혈 여부에 관계없이 환자의 혈액에 오염되기 전이나 후에 일회용 주사기, 혈당 측정용 바늘 또는 수술이나 침습적 처치용 바늘을 포함한 환자에게 사용하여 오염에 노출된 주삿바늘에 의하여 피부가 찢어지거나 긁히거나 찔리는 것을 말하며, 이는 안전을 위해 마련된 주삿바늘 보호 캡을 다시 덮어 씌우는 과정에서도 빈번하게 발생한다.Injury caused by needles may be caused by the use of needles exposed to contaminants, including disposable syringes, blood glucose needles, or surgical or invasive needles, before or after contaminating the patient's blood, whether or not bleeding occurs. Torn, scratched, or stabbed, which frequently occurs in the process of reovering the needle protection caps provided for safety.

혈액 매개 감염 질환이란 인간의 혈액 내에 있는 B형 간염, C형 간염, HIV, 매독균 등의 병원균에 의해 발생하는 질환이다. 병원직원의 혈액 매개 감염 질환은 주삿바늘을 이용한 처치가 발전하고 혈액을 직접 다루는 검사 기술이 많아짐으로 인하여 직원에게 감염을 일으킬 비중이 점차 증가하고 있다. 혈액 노출로 전파되는 질병은Blood-borne infectious diseases are diseases caused by pathogens such as hepatitis B, hepatitis C, HIV and syphilis bacteria in human blood. Hospital staff's blood-borne infections are becoming increasingly infectious due to advances in the use of needles and increased testing techniques to handle blood directly. Diseases that spread from blood exposure

바이러스, 박테리아, 기생충 등 20 여종의 질병이 있다.There are over 20 diseases, including viruses, bacteria, and parasites.

병원에서 일하는 많은 직원들은 혈액 매개성 감염 질환에 노출되고 있으며, 그 중에서도 주삿바늘에 의한 상해가 빈번한 것으로 보고되고 있다.Many employees who work in hospitals are exposed to blood-borne infections, most of which have been reported to injure with needles.

안전주사기는 재사용 방지 및 주사기 바늘의 위험성을 없애기 위한 주사기로서, 종래의 안전주사기로는 주사기 바늘에 커버를 씌우는 방식, 주사기 바늘을 주사기 안으로 회수하는 방식, 바늘이 없이 주사하는 방식 등이 있다.A safety syringe is a syringe for preventing reuse and risk of a syringe needle. Conventional safety syringes include a method of covering a syringe needle, a method of recovering a syringe needle into a syringe, a method of injecting without a needle, and the like.

복수의 종래 안전주사기 중에서 대한민국 특허청 공개번호 10-2004-0031198호를 살펴보면,Looking at the Republic of Korea Patent Office Publication No. 10-2004-0031198 among a plurality of conventional safety syringe,
