The present invention relates to a needleless syringe having a multi-nozzle. More specifically, disclosed is a technical field pertaining to a needleless syringe having a multi-nozzle and a manufacturing method therefor, the needleless syringe injecting a drug solution through an injection nozzle by expanding a pressure-generating liquid by means of energy generated from a pressure-generating unit, wherein precise branch channels are stably formed so as to inject drugs into a plurality of parts by using multiple injection nozzles. Further, the present invention has advantages in that: one energy-generating unit is used and thus nozzles can be densely arranged with a small distance therebetween; when several injections into an affected part are needed, the treatment time can be shortened using multiple injection nozzles; and an inner chamber is inserted into and coupled to or is insert injection-molded in an outer chamber so that more stable and precise branch channels can be formed, and thus multiple drugs can be stably injected into an affected part through multiple injection nozzles. La présente invention concerne une seringue sans aiguille à buse multiple. Est divulgué plus spécifiquement, un domaine technique relatif à une seringue sans aiguille à buse multiple et son procédé de fabrication, la seringue sans aiguille injectant une solution médicamenteuse par une buse d'injection, par expansion d'un liquide de génération de pression au moyen de l'énergie générée par une unité de génération de pression, des voie de ramification précises étant formées de manière stable de façon à injecter des médicaments dans une pluralité de parties en utilisant de multiples buses d'injection. En outre, la présente invention présente les avantages suivants : une unité de génération d'énergie est utilisée et ainsi des buses peuvent être agencées de manière dense avec une petite distance entre elles; lorsque plusieurs injections dans une partie affectée sont nécessaires, le temps de traitement peut être raccourci grâce à l'utilisation de buses d'injection multiples; et une chambre interne est insérée dans une chambre externe, accouplée à celle-ci ou moulée par injection d'insert dans celle-ci, si bien que des voies de ramification plus stables et précises peuvent être formées, et que de multiples médicaments peuvent être injectés de manière stable dans une partie affectée, par le biais de buses d'injection multiples. 본 발명은 멀티노즐이 구비된 바늘 없는 주사기에 관한 것으로서, 보다 상세하게 설명하면, 압력발생유닛에서 발생된 에너지에 의해 압력발생액체가 팽창함에 따라 분사노즐을 통해 약액이 분사되되, 복수 개의 분사노즐을 이용하여 다수의 지점에 약물을 분사할 수 있도록 정밀한 분기유로를 안정적으로 형성하는 멀티노즐이 구비된 바늘 없는 주사기 및 이의 제조방법에 관한 기술분야가 개시된다. 또한, 본 발명은 하나의 에너지 발생부를 이용하여 노즐 간의 간격을 촘촘하게 배치시킬 수 있고, 환부에 여러 번 주사가 필요한 경우 복수 개의 분사노즐을 이용하여 시술 시간을 단축할 수 있는 효과와, 외부챔버의 내측에 내부챔버를 삽입하여 결합 또는 인서트 사출함으로써, 보다 안정적이고 정밀한 분기유로를 형성할 수 있고, 이에 따라 복수 개의 분사노즐을 통해 환부에 복수의 약물이 안정적으로 주사되도록 하는 효과를 얻을 수 있다.
