As shown in fig. 1 and 2, the medical waste liquid collecting barrel with a replaceable liner 20 in one embodiment of the present invention includes a barrel body 10, a liner 20 and a barrel cover 30, wherein the barrel body 10 is made of hard material, and the top of the barrel body 10 has a barrel body opening 12; the inner container 20 is made of soft materials, the inner container 20 is provided with an opening part of the inner container 20, the inner container 20 is detachably arranged in the barrel body 10, and a gap 14 is formed between the inner container 20 and the inner wall of the barrel body 10; the barrel cover 30 is covered at the barrel opening 12 of the barrel body 10, a sealing structure is arranged on the barrel cover 30, the sealing structure is matched with the barrel opening 12 to seal the opening of the inner container 20, and an air extraction joint 32 and a waste liquid collection joint 34 which are communicated with the inner cavity of the inner container 20 are arranged on the barrel cover 30. An air guide joint 40 is arranged on the side wall of the barrel body 10, the air guide joint 40 is provided with a pore canal 41, a first end 44 of the air guide joint 40 extends into the gap 14, and more than two suction ports are arranged on the first end 44 of the air guide joint 40 and are communicated with the pore canal 41.

When the vacuum suction type medical waste liquid collector is used, the inner container 20 is placed in the barrel body 10, the opening part of the inner container is outwards folded and sleeved on the opening part 12 of the barrel body, then the barrel cover 30 is covered to complete the installation of the inner container 20, the air extraction joint 32 and the air guide joint 40 are connected with a vacuum negative pressure source, the waste liquid collection joint 34 is connected with an operation cutter (such as a biopsy needle), and waste liquid is extracted into the flexible inner container 20 through negative pressure suction. After the operation is finished, the barrel cover 30 is opened, and the inner container 20 is taken out. The medical waste liquid collecting barrel with the replaceable liner 20 of the utility model keeps the internal and external vacuum negative pressures of the liner 20 balanced through the air guide joint 40, so that the liner is not deformed by the influence of atmospheric pressure; moreover, more than two suction ports are arranged at the first end 44 of the air guide joint 40 extending into the barrel body 10, the probability that the more than two suction ports are blocked at the same time is small, and the phenomenon that the inner container 20 is tightly attached to the air guide joint 40 to block a channel due to the influence of negative pressure can be avoided.
