Description

Technical Field

[0004] To prepare the foam sclerosing agent, two syringes, one containing 1 mL of liquid sclerosing agent solution and the other 4 mL of air, are connected via a three-way valve. The contents of the two syringes are rapidly pushed back and forth 20 times, creating turbulence and generating foam. Varicose veins are punctured sequentially from proximal to distal. Blood is aspirated to confirm the needle tip is within the vein, and the foam sclerosing agent is slowly injected. An elastic bandage is applied to the lower limb with eccentric pressure. After the procedure, the patient is instructed to walk briskly for 20-30 minutes.

[0005] During the procedure, doctors need to repeatedly and quickly push the contents of two syringes back and forth to prepare a foam hardening agent. This frequent mechanical labor increases the intensity of the doctor's work and workload. Utility Model Content

Under the restriction of the first limiting groove 411, the push rod of the first syringe 1 retracts further into the syringe barrel, and under the restriction of the second limiting groove 412, the push rod of the second syringe 2 extends further out of the syringe barrel. This achieves automated back-and-forth movement of the two syringes, reducing the labor intensity and workload of doctors.

[0066] When it is necessary to remove syringe 1 and syringe 2, pull locking block 71 out to the outside of locking groove 541, then remove positioning ring 53, pull locking block 81 out to the outside of locking groove 561, then remove positioning ring 55, and then syringe 1 and syringe 2 can be removed.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
