[0028] Combination Figures 1 to 3 The specific working principle of the portable electric saline shaker 100 of this utility model is as follows:

[0029] During right ventricular echocardiography, the second three-way connector 5 connects its second port to the first port, and the first three-way connector 4 connects its third port to the first port. This allows the saline inlet 12 to connect to the first injection port 212 via the second three-way connector 5 and the first three-way connector 4. Saline entering from the saline inlet 12 can then flow into the first oscillation space 211 of the first syringe 2 through the first injection port 212. Then, the first three-way connector 4 connects its first port to the second port. The first linear reciprocating motor module 61 drives the first injection rod 22 of the first syringe 2 to reciprocate, and the second linear reciprocating motor module 62 drives the second injection rod 32 of the second syringe 3 to reciprocate. This causes the saline solution to repeatedly flow into the first oscillation space 211 of the first syringe 2 and the second oscillation space 311 of the second syringe 3. The mixture is vibrated to mix saline solution with air, forming a mixture that remains in the first vibration space 211 of the first syringe 2 or the second vibration space 311 of the second syringe 3. The mixture is then connected to the first or second interface of the syringe 2 via the first three-way tube 4, and to the third interface via the second three-way tube 5. This connects the first or second vibration space 211 containing the mixture to the injection outlet 13. Finally, the first injection rod 22 of the first syringe 2 is moved by the first linear reciprocating motor module 61 to eject the mixture, or the second injection rod 32 of the second syringe 3 is moved by the second linear reciprocating motor module 62 to eject the mixture. The mixture is then discharged through the injection outlet 13 and injected into the patient. Combined with ultrasound imaging technology, a detailed examination of the right ventricular angiography can be performed. After use, the top cover 14 and bottom shell 15 of the housing 1 can be disassembled to facilitate the removal and replacement of the first syringe 2, the second syringe 3, the first three-way tube 4 and the second three-way tube 5. The removed first syringe 2, second syringe 3, first three-way tube 4 and second three-way tube 5 are disposed of as medical waste to reduce contamination and cross-infection.

[0030] In summary, the portable electric saline agitator 100 of this invention integrates the first syringe 2, the second syringe 3, the first three-way valve 4, the second three-way valve 5, the first linear reciprocating motor module 61, and the second linear reciprocating motor module 62 within the housing 1. The first syringe 2, the second syringe 3, the first three-way valve 4, the second three-way valve 5, the first linear reciprocating motor module 61, and the second linear reciprocating motor module 62 are compact in size, making them easy to carry to various examination environments. Secondly, this invention enables automatic agitation, eliminating the need for manual agitation, greatly saving manpower, simplifying operation, and achieving efficient and stable agitation of saline solution, thus improving the accuracy and clarity of contrast imaging examinations. Furthermore, the portable electric saline agitator 100 of this invention has a wide range of applications, suitable not only for routine examinations in hospitals but also for emergency rescue, medical assistance in remote areas, and other scenarios.
