Description

Technical Field

[0001] The utility model relates to the technical field of liquid sub-packaging, and particularly relates to a desktop liquid sub-packaging device. Background Art

[0002] In the process of drug production, aseptic operation is a crucial link, which is directly related to the safety and effectiveness of drugs. Aseptic sub-packaging operation mainly involves liquid drugs such as injections and medicinal liquids. These drugs must be guaranteed to be free of microbial contamination during production and use to avoid potential health risks to patients.

[0003] The establishment and maintenance of an aseptic environment is a complex process, which involves multiple factors. First of all, operations need to be carried out in a clean room or an aseptic room. These rooms control the cleanliness of the air through a high-efficiency filtration system to reduce microbial and particulate contamination. The level of a clean room is usually divided according to the number of suspended particles in the air. The higher the level, the stricter the requirements for air cleanliness.

[0004] In order to avoid bacterial contamination of drugs during sub-packaging, the sub-packaging operation of drugs is usually carried out in an aseptic room, and drugs are sub-packaged through drug sub-packaging equipment. Traditional drug sub-packaging equipment usually adopts a turntable structure. For example, in the invention patent with the publication number CN113753837A and the invention name of an automatic sub-packaging system and method for a small batch of radioactive liquid medicine, such sub-packaging equipment usually includes a turntable mechanism. During sub-packaging, medicine bottles are placed on the turntable mechanism, and injection pump modules, rubber stopper clamping modules, aluminum cap clamping modules, capping modules, etc. are distributed around the turntable mechanism. The rotation of the turntable drives the medicine bottles to pass through each module in turn to achieve the sub-packaging of drugs.

[0005] However, the existing such drug sub-packaging equipment is large in volume and can only operate in a large aseptic room. As the space of the aseptic room increases, the construction cost and operation cost of the aseptic room also increase, thereby increasing the cost of drug sub-packaging.

[0006] Therefore, there is an urgent need to provide a liquid sub-packaging device with a small volume and a compact structure, which can operate in an aseptic room with a small space and reduce the cost of drug sub-packaging. Summary of the Invention

[0009] The swing arm mechanism comprises a swing arm and a driving mechanism for driving the swing arm to swing; the bottle body is moved along the movable limiting channel by the swing arm.

[0010] Preferably, two guide plates are arranged opposite to each other on the frame, and the movable limiting channel is located between the two guide plates.

[0011] Preferably, a slide groove is provided on the swing arm; when the swing arm moves the bottle body, the bottle body is placed in the slide groove.

[0012] Preferably, the driving mechanism comprises a motor and a swing shaft, the motor and the swing shaft are transmission-connected; and the swing arm is connected to the swing shaft.
