Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a foam hardening agent preparation device for rapidly collecting clean air.

Background

Currently, a hardening treatment mode called as foam sclerosing agent is widely applied to clinical medical work, mainly aims at diseases such as great saphenous vein varicosity, maxillofacial vein hemangioma, liver cavernous hemangioma, esophageal and gastric varicosity, hepatic cyst, renal cyst, ovarian cyst and the like, and is an important means of minimally invasive medical treatment.

The foam hardening agent is prepared by temporarily preparing the poly-cinnamic alcohol solution and air according to a certain volume ratio in a treatment process, and compared with the pure poly-cinnamic alcohol solution which is directly used without being mixed with the air, the foam hardening agent has the advantages of good hardening effect, low consumption of the poly-cinnamic alcohol, good cost-benefit ratio and outstanding advantages in the field of treatment of hepatic cyst and renal cyst with larger volume.

However, a regulatory problem, i.e., sterile handling requirements, has heretofore been addressed and has not been addressed in the formulation of a foam sclerosant in therapeutic procedures. The lauromacrogol solution is sterilized, and is prepared into a foam hardening agent which needs to be injected into a focus of a human body through a puncture needle and other tools, belonging to the application in the human body. The air used to dispense the foam hardener must then be sterile.

However, in practice, people directly use a syringe to draw air in a treatment site, and the degree of bacteria and dust contained in the air varies depending on the environment of the treatment site. Even in hundreds of laminar flow operating rooms, the air in their environment is theoretically not absolutely sterile and dust-free, and even more so many treatment sites are located in outpatients, ultrasound examination rooms or other environments where disinfection and isolation conditions are extremely crude. The air in the environment is directly used and is prepared into the foam sclerosing agent with the lauromacrogol solution to be injected into the focus of a human body, so that the great hidden danger exists in the aspect of sterility requirements, and the medical ethical requirements are not met, because the foam sclerosing agent is prepared by informing a patient when the patient is informed of consent before treatment, the patient is difficult to accept, and if the patient is not informed of consent in the field, the informed consent principle is violated.

In view of the above, there is a need for a device that can help a physician quickly obtain clean air for use in deploying a polylauryl foam sclerosing agent during a procedure.

Disclosure of Invention

The utility model provides a foam hardener preparation facilities of clean air of quick collection, includes three way type connector, three way type connector includes that the intracavity is provided with the first interface of filter disc, is used for connecting the second interface of the syringe that contains the lauromacrogol solution and the third interface of the empty syringe of suction air, the lumen junction of three interfaces of three way type connector is provided with three-way rotary valve.
