An infusion apparatus is a medical apparatus which is quite commonly used at present and is mainly used for carrying out intravenous infusion on patients. At present, most of infusion sets are disposable, and the demand is very large, so that higher productivity and production efficiency are required. The general transfusion device mainly comprises a bottle needle (with an exhaust valve), a first pipe body, a dropping funnel, a second pipe body, a filter (part of which has a one-way valve function), a regulator (for regulating flow) and a transfusion needle (for puncturing a human body). The bottle needle, the exhaust valve, the first pipe body, the dropping funnel, the second pipe body and the filter are sequentially connected and fixed, and the transfusion needle is detachably connected to the filter.

In the manufacturing process of the infusion apparatus, a coiled tube body is generally cut off firstly, so that a first tube body and a second tube body are obtained, then a regulator is installed on the second tube body, then a filter and a dropping funnel are installed at two ends of the second tube body, one end of the first tube body is installed with the dropping funnel, and the other end of the first tube body is connected with a bottle needle, so that an infusion apparatus main body is formed; then the tightness of the infusion set main body needs to be detected, the bottle needle and the filter are inflated generally, the air is kept for a period of time, and if the leakage rate is within the qualified range, the infusion set main body is regarded as qualified. If the filter has the function of a one-way valve (the filter flows from the dropping funnel to the transfusion needle), only one end of the bottle needle needs to be inflated.

Since the installation of the bottle needle, the filter, the dropping funnel and the first tube body needs to be divided into independent processes, the processes are long, which results in low efficiency. In the detection process, pressurized gas is manually filled, and then the infusion set is placed in water to observe whether bubbles emerge or not so as to judge the tightness of the infusion set main body.
