Working principle: both the push pump body 1 and the syringe body 2 are common medical equipment tools in the prior art. The push pump body 1 combines electronic technology and mechanical technology to achieve control of drug dosage and push speed, usually including a barrel wall clamp and a piston rod clamp for the syringe body 2, as well as a control panel, a push rod, and a handle. Its working principle is well known, so it is not described in detail in this case. After the control panel adjusts the parameters, the push rod contracts to inject the medicine in the syringe body 2 into the infusion tube 31. The medicine flows along the tube wall to the filter tube 33, and the medicine is filtered through the filter mesh 5 between the filter bucket 1 34 and the filter bucket 2 43. Impurities are filtered into the collection hole, and the filtered medicine passes through the filter hole of the filter bucket 2 43 into the inner cavity of the mounting tube 41, and continues to flow along the infusion tube 2 6, and finally discharged from the infusion needle 7.

The infusion tube 31 can also be quickly pulled out from the syringe body 2. The infusion tube 2 6 and the mounting tube 41 are detachably connected by a pipe joint 44, and can be quickly separated. The various structures are modularized, which is convenient for disassembly, classification, cleaning or direct replacement after use.

The filter tube 33 and the mounting tube 41 are threadedly connected by a threaded ring 35 and a threaded groove 42, which facilitates installation and disassembly. After tightening, they can be sealed and connected by a sealing ring 36 to avoid the problem of leakage of the medicine. After loosening and separating, the filter tube 33 and the mounting tube 41 can be cleaned separately. The mounting tube 41 is used to circulate the filtered medicine, so it can be directly rinsed. The filter screen 5 is directly removed from the filter bucket 34 for replacement. The residual impurities are concentrated in each collection hole and can be quickly removed by flushing. After opening the tube cover 38, the inner cavity of the filter tube 33 can be opened, which is convenient for cleaning the inner cavity and removing other residual impurities, thereby improving the thoroughness of cleaning and extending the service life. The tube cover 38 is tightly attached to the inner wall of the cleaning hole 37 through a sealing gasket, which can avoid the problem of medicine overflow and ensure the sealing during use.

Compared with the comparative technology, this case adopts modular connection between various structures, which can be easily installed and disassembled. At the same time, the filter tube 33 and the installation tube 41 are detachably connected, and the filter net 5 can be freely loaded and unloaded, which improves the flexibility of use. After disassembly and separation, it can be thoroughly cleaned, thereby improving the reuse rate and service life.
