Examination of fallopian tube patency is one of the diagnostic tests for infertility. Hysterosalpingography (HSG) is currently the most recommended and commonly used method to examine the fallopian tubes, with advantages such as simple operation, minimal trauma, and high accuracy.

If conception does not occur within a year, or for women over 40 after six months, undergoing HSG is advisable. It is especially recommended for those with histories of ectopic pregnancy or pelvic inflammatory disease.

Safe Material: Made of high-quality medical silica gel, soft to the touch and non-toxic. It is non-irritating and reduces risk during examination.

Reduced Infection Risk: The disposable design eliminates cross-infection, while the smooth surface prevents bacterial adhesion.

1. Lubricate the tip and shaft of the catheter generously.
2. Carefully insert the catheter tip and balloon into the uterus.
3. Connect the two-way valve to a 2.5ml syringe with 1.5ml sterile water; inject to inflate the balloon, then close the valve.
4. Connect the tubal injection chamber to the liquid instrument for extraction or injection.
5. After use, open the valve, remove all sterile water from the balloon, and extract the tube.

Moderate Tube Diameter: The 5FR size ensures smooth contrast medium passage while avoiding irritation or dilation damage.

Soft and Flexible: Medical silica gel adapts to physiological curvatures, increasing surgical success rates.

Clear Imaging: Special treatment on the tube body ensures high visibility under imaging techniques for accurate diagnosis.
