Problems solved by technology
[0002] At present, after the indwelling needle used in clinical practice is completed, in order to reduce the drug residue in the indwelling needle and avoid blood backflow, it is necessary to use a syringe equipped with normal saline to flush and seal the cannula, manually rinse, and push the thumb once and then stop. Putting rods requires many steps and low efficiency. The pushing force of a person’s thumb varies from person to person, and the consistency of each operation cannot be guaranteed.
[0003] In the prior art, most of the pipe flushing and sealing devices adopt a three-way pipeline, one pipeline is a liquid medicine output passage, and the other two pipelines are respectively connected to two syringes, and a flushing fluid (normal saline or sodium lactate) is housed in one syringe. Solution), the other syringe is filled with lock solution (heparin saline), but this device needs to change the three-way pipeline, which is inconvenient to operate and easy to cause infection
