Technical Field
[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a household wart freezing detection pen. Background Art
[0002] Warts are benign epidermal growths caused by human papillomavirus infection of the skin and mucous membranes. The manifestation of this benign growth is the appearance of nodules or papules that are raised or slightly raised on the skin or mucous membranes. There are many ways to treat warts, mainly including laser, freezing and drug therapy. In clinical practice, patients who choose freezing generally use liquid nitrogen to freeze the warts, causing the wart cells to necrotize and fall off, thereby achieving the purpose of removing the warts.
[0003] When warts are subjected to cryotherapy, it is usually inconvenient to detect the frozen warts. Now a home-use wart cryodetection pen is proposed. Utility Model Content

[0010] Further technical solution: a liquid inlet tank is fixedly installed at one end of the pen body, a liquid storage cavity is opened inside the liquid inlet tank, and a liquid outlet is opened on the surface of the liquid inlet tank.
[0011] Further technical solution: A symmetrical spring is fixedly installed inside the liquid inlet bin, and the other end of the spring is fixedly connected to the bottom end of the liquid nitrogen bin and the white acetic acid bin respectively. A symmetrical hollow ejector pin is fixedly installed inside the liquid inlet bin, and the hollow ejector pin and the sealing gasket are in the same horizontal plane.
[0012] Further technical solution: the surface of the liquid inlet bin is rotatably connected with a symmetrical rotating shaft, the surface of the rotating shaft is fixedly installed with a symmetrical connecting rod, the end of the connecting rod is fixedly installed with a circular ring block, and a plurality of through holes are opened inside the circular ring block.

[0014] Beneficial Effects
[0015] The utility model provides a household wart freezing detection pen and a fire extinguisher, which have the following beneficial effects compared with the prior art:
[0016] 1.
