Inject the medicine to be fed into the dosing tube through the dosing port, that is, the medicine pushes the sealing plug to move downward until it is separated from the flow hole, and the shielding plate and the special-shaped frame move synchronously, that is, the compression spring is stretched by force. After stopping the injection of medicine, the sealing plug is pushed through the flow hole under the elastic force of the compression spring to block the flow hole, effectively preventing the leakage of the medicine and achieving a sealing effect. It can also prevent external air, dust, etc. from falling into the dosing tube to avoid respiratory infection. The area of ​​the shielding plate is larger than the area of ​​the flow hole to ensure the comprehensive coverage of the shielding plate, further enhancing the sealing effect of the dosing tube and avoiding the influence of air leakage on the dosing rate;

[0019] Rotate the catheter to drive the connecting pipe to rotate, and use the threaded connection between the connecting pipe and the transition pipe to unscrew the catheter and separate the catheter and the transition pipe so that the catheter and the injection head can be subsequently cleaned and maintained to avoid cross infection during use.
