The present design relates to a manual vacuum suction device, comprising: a trunk body (10) which is provided with a grip frame (12) at one end and is formed with a suction hole (14) at the other end； a plurality of cylinders (20) which are formed as partitions on the trunk body (10) and in which backflow-preventing valves (22) provided at one end are formed so as to link through to the suction hole (14) via a travel hole (24)； a plurality of pistons (30) which are housed together with springs (32) in the cylinders (20) where they travel in a linear reciprocating motion, and of which the end parts are connected to a single grip (34)； and a pressure measuring and adjusting part (40) which is installed on the travel hole (24) so as to link through to the same, and which is provided so as to measure and adjust the pressure. Consequently, the present design has advantageous effects in that a high suction force is generated over a short stroke distance and the time taken to reach a set pressure is substantially reduced since the cylinders and pistons are formed as partitions in a plurality of locations with a unitary size, and also in that pressure measurement and pressure adjustment via the pressure measuring and adjusting part is easy and in that safety failures such as damage to skin due to momentary increases in pressure are prevented by means of an excess-pressure valve.La présente invention concerne un dispositif d'aspiration-vidange à main, comprenant: un corps de tronc (10) qui présente une structure de poignée (12) à une extrémité et présente un orifice d'aspiration (14) à l'autre extrémité； une pluralité de cylindres (20) qui sont formés comme des séparations sur le corps de tronc (10) et dans lesquels des soupapes anti-refoulement (22) présentes à une extrémité sont formées de manière à déboucher sur le trou d'aspiration (14) par l'intermédiaire d'un trou de passage (24)； une pluralité de pistons (30) qui sont logés avec des ressorts (32) dans les cylindres (2
