의약품 주입장치 {APPARATUS FOR SELF-INJECTING LIQUIDMEDICINE}Pharmaceutical Injection Device {APPARATUS FOR SELF-INJECTING LIQUIDMEDICINE}

본 고안은 휴대 및 사용이 간편한 자기주입방식의 의약품 주입장치에 관한 것으로서, 본 고안의 의약품 주입장치는, 본 출원인이 선 출원 특허 제99-5514호의 변형 예에 관한 것이다.The present invention relates to a medicine injection device of a self-injection method that is portable and easy to use, the medicine injection device of the present invention relates to a modification of the prior application No. 99-5514.

본 고안과 관련이 있는 종래의 기술로서는, 예를 들면 파워 어시스트장치가 공지되어 있는데, 통상적으로, 요로조영술이나 혈관조영술 등에서 이용되는 상기의 파워 어시스트장치는, 그 구성이 복잡하고, 또한 별도의 동력장치 및 전동장치를 요구하고 있기 때문에 제작비용이 비싸며, 무엇보다도 사용방법이 대단히 복잡하여 숙련된 의사가 아니면 사용하기 어렵고 장치가 거대하여 휴대할 수 없다는 단점이 있다.As a conventional technique related to the present invention, for example, a power assist device is known. Usually, the power assist device used in urinary angiography, angiography, or the like has a complicated configuration and a separate power source. Since the device and the transmission are required, the manufacturing cost is expensive, and above all, the method of use is very complicated, so that it is difficult to use without a skilled doctor and the device is huge and cannot be carried.

이에 본 출원인은 특허출원 제99-5214호 및 실용신안등록 출원 제99-5610에서, 휴대 및 사용이 간편한 의약품 주입장치를 제안한 바 있는데 상기의 장치의 경우 도4에서 참조된 바와 같이 의약품 주입시 종방향으로 이동하는 밀대의 힘의 스프링(23)의 팽창력을 이용하여 실린지에 압력을 가하는 방식 이었으나 이 방식은 스프링의 탄성에 따라 밀대를 밀어내는 힘의 크기가 불균형을 이루기 때문에 본 고안은 독립된 실린더를 이용하여 실린지의 사용상태에 따라 가스 실린더, 또는 진공 실린더를 사용하여 의약품 주입시 종방향으로 이동하는 밀대의 압력이 실린지에 충격이 없고 일정한 힘으로 실린지에 압력이 가해 지도록 고안하였다.Accordingly, the present applicant has proposed a drug injection device that is easy to carry and use in Patent Application No. 99-5214 and Utility Model Registration Application No. 99-5610. In the case of the device, as described in FIG. The pressure was applied to the syringe using the expansion force of the spring 23 of the force of the push rod moving in the direction, but this method is because the magnitude of the force pushing the push rod in accordance with the elasticity of the spring to form an imbalance According to the use condition of the syringe, the pressure of the push rod moving in the longitudinal direction during injection of medicine by using gas cylinder or vacuum cylinder is designed to apply the pressure to the syringe with no impact and constant force.

이하, 첨부된 도면을 참조하여, 본 고안의 따른 의약품 주입장치의 구성에 관해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, it will be described in detail with respect to the configuration of the drug injection device according to the present invention.

도1은 본 고안에 따른 의약품 주입장치의 개략적인 구성을 도시한 분해사시도로서, 본 고안의 의약품 주입장치는, 도면에 도시된 바와 같이 독립된 실린더(1)와 상부캡(3)과 서로 연결해 주며 밀대를 잡아주는 중간 연결부(2)로 구성되어 있으며, 다시 상기의 중간 연결부(2)는 발사 버튼(7)이 삽입홈(21)으로 삽입하게 되며, 중간 연결부(2)의 발사버튼(7)이 삽입되는 반대쪽 내측에 홈이 파여 있고, 버튼 스프링(8)이 안착되어, 항상 바깥쪽으로 부세력이 작용하게 된다.1 is an exploded perspective view showing a schematic configuration of a drug injection device according to the present invention, the drug injection device of the present invention, as shown in the figure is connected to the independent cylinder (1) and the upper cap (3) Consists of the middle connecting portion (2) for holding the push rod, the middle connecting portion 2 is the firing button 7 is inserted into the insertion groove 21, the firing button 7 of the intermediate connecting portion (2) A groove is dug in the opposite side into which it is inserted, and the button spring 8 is seated so that the bias force always acts outward.

상부캡(3)은 대경봉(11)과 소경봉(12)이 결합된 해드(13)로 구성된다. 상부캡(3)에 실린지(16)가 삽입되며, 실린지(16)의 니들(22) 길이에 따라 상기 바늘의 노출길이를 적절히 조절할 수가 있도록 하였다. 상기 독립된 실린더(1)는 실린지(16)의 사용상태에 따라 도2에 도시한 바와 같이 커버(4)와 피스톤 패킹(6) 사이의 가스실(14)에 압축성 가스가 포화 되어 있는 가스 실린더(1)와, 피스톤 패킹(6)의 과 밀대 패킹(10)사이 내부를 진공 상태가 생성 되도록 만든 진공실(19)로 구성되어 있다.The upper cap 3 is composed of a head 13 is coupled to a large diameter rod 11 and a small diameter rod 12. The syringe 16 is inserted into the upper cap 3, and the exposure length of the needle can be properly adjusted according to the length of the needle 22 of the syringe 16. The independent cylinder 1 is a gas cylinder in which the compressible gas is saturated in the gas chamber 14 between the cover 4 and the piston packing 6 as shown in FIG. 1) and a vacuum chamber 19 which is configured to generate a vacuum state between the overpack packing 10 of the piston packing 6.

이하에서는, 상기와 같이 구성되는 본 고안의 의약품 주입장치를 사용하는 방법에 관하여 설명한다.Hereinafter, a method of using the medicine injection device of the present invention is configured as described above.

도3에서 참조되는 바와 같이 본 고안의 의약품 주입장치로 주사하기 위해서는 먼저, 독립된 실린더(1)와 중간연결부(2)를 결합하고, 발사버튼(7)을 버튼 스프링(8)과 함께 삽입하여 고정한 다음, 실린더(1)의 밀대(9)를 실린더(1)내부에 삽입하면 발사버튼(7)에 걸리게 되고 이때 밀폐된 가스실(20)의 압축가스는 압축되고 진공실(19)은 형성된 공간에 의해 진공이 발생된다.In order to inject the medicine injection device of the present invention, as shown in Figure 3, first, the independent cylinder (1) and the intermediate connection (2) is combined, and the firing button (7) with the button spring (8) is fixed Next, when the push rod 9 of the cylinder 1 is inserted into the cylinder 1, it is caught by the firing button 7 and the compressed gas of the closed gas chamber 20 is compressed and the vacuum chamber 19 is formed by the space formed. Vacuum is generated.

이러한 상태에서 상부캡(3)에 실린지(16)를 삽입하고, 위에 상기한 구성품과 결합하면 된다.In this state, the syringe 16 is inserted into the upper cap 3, and the above components are combined with each other.

그 후, 주입장치의 선단부를 피부에 갖다 댄 상태에서 중간 연결부(2)에 설치되어 있는 발사 버튼(6)을 누르면 밀대(9)의 고정장치가 풀려 가스실의 압축 가스는 팽창력으로 밀대(9)의 끝에 고정된 피스톤(5)을 밀게되고 반대의 진공실(19)은 피스톤(5)을 당기게 되어 결국 밀대(9)는 실린지(16)를 밀게 되므로 니들(22)은 피부내로 삽입되며, 밀대(9)는 계속 종방향으로 진행되면서 주사액은 피부로 주입된다.Thereafter, when the tip button of the injection device is placed on the skin and the firing button 6 installed on the intermediate connecting portion 2 is pressed, the fixing device of the push rod 9 is released and the compressed gas in the gas chamber is pushed by the push rod 9 by the expansion force. The piston 22 fixed to the end of the pusher and the opposite vacuum chamber 19 pulls the piston 5 so that the pusher 9 pushes the syringe 16 so that the needle 22 is inserted into the skin and the pusher (9) continues in the longitudinal direction while the injection solution is injected into the skin.

만일 주사액의 토출압을 변경하려면 필요에 따라 가스실(20) 상단의 압축밸브(18)을 개방하면 진공력으로만 밀대의 힘이 작용되고, 또는 압축가스의 팽창력만으로 작용시키려면 진공실(19)의 진공밸브(17)를 개방하면 된다.If the discharge pressure of the injection liquid is opened, if necessary, the compression valve 18 of the upper end of the gas chamber 20 is opened, and the pushing force is applied only by the vacuum force, or to operate only by the expansion force of the compressed gas, The vacuum valve 17 may be opened.
