Description

유로변환식 의약품주입기{Infuser of Passage exchange type}Euro-Converting Drug Injector {Infuser of Passage exchange type}

본 발명은 환자의 통증을 억제하기 위해 약액을 주입하는 기구인 의약품주입기에 관한 것으로, 더욱 상세하게는 상기 의약품주입기를 통하여 환자에게 약액을 주입할 때 지속적으로 주입하는 기능을 필요에 따라 선택적으로 개.폐할 수 있으며 간헐적으로 통증이 발생되는 싯점에는 환자스스로 간편하게 약액을 주입할 수 있도록 하여 약액이 필요이상 환자에게 공급되는 것을 방지 할 수 있도록 하는 유로변환식 의약품주입기에 관한 것이다.The present invention relates to a medicament injector which is a device for injecting a medicament to suppress the pain of the patient, and more particularly, to selectively inject the medicament into the patient through the medicament At the point where pain can occur and intermittent pain occurs, it is related to a Euro-converting medicine injector that allows the patient to easily inject the medicine solution to prevent the medicine from being supplied to the patient more than necessary.

일반적으로 의약품주입기라 함은, 환자에게 발생되는 통증을 관리.조절하기 위해 진통제등과 같은 약액을 어떠한 풍선이나 주사기 속에 저장했다가 이를 신경계통(예:척추)이나 혈관(정맥)에 소량씩 지속적으로 주입시켜 줌으로써 소량의 약액으로도 마취.진통효과를 지속시키도록 하는 기구이다.In general, a medicine injector stores a medicine, such as painkillers, in a balloon or syringe to manage and control pain in a patient, and then a small amount of the medicine is kept in a nervous system (e.g., a spine) or a blood vessel (vein). It is a device that maintains anesthesia and analgesic effect even with a small amount of chemical solution by injecting it.

이러한 기구를 통하여 필요한 약액을 환자에게 일정한 양씩 지속적으로 주입함으로써 소정의 치료효과를 얻을 수 있음은 물론, 통증을 완화 시키는데 많은 기여를 하게 된다.By continuously injecting the necessary drug solution to the patient in a constant amount through such a device, a certain therapeutic effect can be obtained as well as a great contribution to relieve pain.

근래에 들어서는 상기 의약품주입기가 그 용도에 따라 다양하게 개발되고 사용의 편리성을 증대시키기 위해 그 기능도 다양해 지고 있는 추세인데, 그 종류는대체적으로 기계식과 기구식으로 분류할 수 있다.In recent years, the drug injector has been developed in various ways according to its use, and its function is also diversified in order to increase the convenience of use, which can be classified into mechanical and mechanical types.

우선, 기계식은 전기와 같은 동력원에 의해 작동되는 것이고, 후자의 경우인 기구식은 풍선이나 스프링의 탄성을 이용하여 약액주입이 이루어 질 수 있도록 하는 것이다.First of all, the mechanical type is operated by a power source such as electricity, and the latter type mechanical type is to allow chemical injection by using the elasticity of a balloon or a spring.

한편, 상기 기계식은 전기등의 동력원이 별도로 필요한 것이어서 무겁고, 환자가 이동시는 사용할 수 없는등의 불편함이 있어 후자의 경우인 기구식의 이용이 더욱 보편화 되고 있다.On the other hand, the mechanical type is heavy because it requires a separate power source such as an electric light, and there is inconvenience such as not being able to use it when the patient moves, and the use of the mechanical type in the latter case is becoming more common.

이러한 기구식으로 된 의약품주입기는, 그 일반적인 구조및 작동원리가 첨부된 도면의 도 1 에 도시된 바와같다.Such a mechanical injector is as shown in Figure 1 of the accompanying drawings, the general structure and principle of operation.

즉, 소정의 약액이 저장되어지는 약액저장기(110)는 반구형모양의 커버(112)가 투명재질로 구성되면서 그 일측에는 약액주입구(116)가 형성되어 이 약액주입구(116)를 통하여 실리콘재질의 풍선형저장기(114)내에 약액이 주입되어지게 된다.That is, the chemical liquid reservoir 110 in which the predetermined chemical liquid is stored is formed of a semi-spherical cover 112 is made of a transparent material, while the chemical liquid inlet 116 is formed at one side thereof, and the chemical liquid inlet 116 is formed of a silicon material. The chemical liquid is injected into the balloon-shaped reservoir 114.

상기 자체탄성을 갖는 풍선형저장기(114)내에 주입되어진 약액은 그 자체의 수축력에 의해 주입되어진 약액을 소정의 압력으로 가압하여 약액배출구(118)를 통하여 제1, 제2도관(122)(124)으로 배출시키게 되는 것이며, 최종적으로 상기 제3도관(126)을 통과하게 되는 약액은 주사바늘(미 도시함)을 매개로 환자에게 주입되어지게 된다.The chemical liquid injected into the balloon-shaped reservoir 114 having self-elasticity presses the chemical liquid injected by its contracting force to a predetermined pressure, and then, through the chemical liquid discharge port 118, the first and second conduits 122 ( 124), and finally the chemical liquid passing through the third conduit 126 is injected into the patient through an injection needle (not shown).

또한, 종래의 의약품주입기에 있어서는 환자의 통증정도가 항상 일정한 것이 아니고 때에 따라 변화하기도 하기 때문에 통증이 극심한 경우에는 통증치료에 예상했던 양보다 더 많은 약액이 일시에 공급될 수 있도록 하기 위하여 약액공급량조절장치(PCA:Patient Controled Analgesia)가 제1,제2도관(122)(124)과 제3도관(126)사이에 적용되어져 있다.In addition, in the conventional medicine injector, the pain level of the patient is not always constant and may change from time to time, so when the pain is extreme, the amount of the medicine supply is adjusted so that more medicine can be supplied at a time than the amount expected for the pain treatment. A device (Patient Controlled Analgesia) is applied between the first and second conduits 122 and 124 and the third conduit 126.

그러나 환자의 통증이 경감되어 가는 때에는 지속적주입기능은 필요가 없고 간헐적으로 통증이 있을 경우에만 일시적으로 주입할 필요가 있음에도 불구하고 종래의 의약품주입기는 지속적주입기능을 필용시 단절시키는 기능이 없이 한 꺼번에 다량의 약액을 일시에 주입하는 기능만이 함께 부여되어 있어, 지속적 약액공급을 중단시킬 필요가 있어도 이를 할 수 없는 문제점이 있었다.However, even when the pain of the patient is reduced, the continuous injection function is not necessary, and even though it is necessary to temporarily inject only when there is an intermittent pain, the conventional medicine injector does not have the function of cutting off the continuous injection function. Only a function of injecting a large amount of chemical at a time is given together, there was a problem that can not do this even if it is necessary to stop the continuous supply of chemical.

상기의 문제점을 개선하기 위한 방안으로 도관의 소정위치에 클램프를 부착하여 상기 클램프를 통하여 도관의 유로를 선택적으로 차단시킬 수 있도록 하는 방안이 강구될 수도 있으나, 이는 도관이 꺾임방지(Anti-Kinking)를 위하여 내경은 작고 벽은 두꺼운 연질의 플라스틱재 튜브로 이루어진 점을 감안하면 상기 클램프를 통하여 도관의 유로를 차단한다는 것은 현실적으로 곤란하다는 문제점이 발생하게 된다.In order to improve the above problems, a method of attaching a clamp at a predetermined position of the conduit to selectively block the flow path of the conduit through the clamp may be devised, but this is to prevent anti-kinking of the conduit. Considering that the inner diameter is small and the wall is made of a thick soft plastic tube, it is difficult to block the conduit flow path through the clamp.

이에 본 발명은 상기의 제반 문제점을 해소시키기 위해 안출된 것으로, 본 발명은 의약품주입기를 통하여 환자에게 약액을 지속적으로 주입하는 기능은 선택적으로 개.폐할 수 있으며 간헐적으로 통증이 발생되는 정도에 따라 환자스스로 간편하게 약액공급을 선택적으로 할 수 있도록 하여 약액이 필요이상 환자에게 공급되는 것을 가능한 한 방지 할 수 있도록 하는 유로변환식 의약품주입기를 제공하는데 그 목적이 있는 것이다.Accordingly, the present invention has been made to solve the above problems, the present invention is a function of continuously injecting the drug solution to the patient through the drug injector can selectively open and close the patient depending on the degree of pain occurs intermittently The aim is to provide a euro-converting drug injector that allows the user to easily and selectively supply the medicine solution so that the medicine can be supplied to the patient more than necessary.

상기의 목적을 달성시키기 위한 본 발명에 따른 유로변환식 의약품주입기는, 공급되는 약액의 지속적주입기능 및 일시적주입기능이 병행되어진 의약품주입기의 약액공급량 조절장치에 있어서, 상기 약액공급량 조절장치내의 지속적주입라인의 소정위치에 약액의 공급을 차단시킬 수 있도록 하는 1방향밸브를 장착시키도록 한 것을 특징으로 한다.In order to achieve the above object, the euro-converting drug injector according to the present invention is a medicine supply amount adjusting device of a medicine injector in which both a continuous injection function and a temporary injection function are supplied, and a continuous injection line in the medicine supply amount control device. Characterized in that it is equipped with a one-way valve to cut off the supply of the chemical liquid at a predetermined position of.
