摘要：
A suction pump valve nozzle according to an embodiment may comprise a nozzle body having an airtight inner space, and a pressure control unit which is provided at one side of the nozzle body and controls the pressure inside the nozzle body, wherein a negative pressure can be formed inside the nozzle body, and the pressure control unit can allow the inner space of the nozzle body and the outside of the nozzle body to communicate with each other to prevent an excessive negative pressure inside the nozzle body, and thus may prevent side effects of the treatment, such as discomfort due to excessive suction, long-lasting bruise, hyperpigmentation, and blisters, thus securing the safety of cupping therapy. A cupping apparatus for controlling a pressure reduction rate according to another embodiment comprises: a first cupping cup having a protrusion which is capable of being coupled to a suction pump and through which air is discharged； a second cupping cup which is arranged at the lower end of the first cupping cup and which is to be attached to a to-be-treated site； and at least one pressure reduction control unit provided at the top end of the second cupping cup, wherein the pressure reduction control unit may supply, to the inside of the second cupping cup, a negative pressure generated inside the first cupping cup when sucking air inside the first cupping cup, at time intervals.La présente invention concerne une buse de soupape de pompe d'aspiration pouvant comprendre un corps de buse comportant un espace interne étanche à l'air, et une unité de commande de pression qui est fournie sur un côté du corps de buse et qui commande la pression à l'intérieur du corps de buse, une pression négative pouvant être formée à l'intérieur du corps de buse, et l'unité de commande de pression pouvant permettre à l'espace interne du corps de buse et à l'extérieur du corps de buse de communiquer l'un avec l'autre pour prévenir une pression négative excessive à l'intérieur du corps de bu
