Handheld Liquid Nitrogen Sprayer: A Powerful Tool for Cryotherapy in Dermatology

In clinical dermatology treatment, precise and efficient equipment is crucial for ensuring therapeutic efficacy. This handheld liquid nitrogen sprayer was designed to meet this need, perfectly combining cryogenic freezing technology with a portable design, making it a practical tool for medical professionals treating various skin lesions.

Using liquid nitrogen as the refrigerant, it relies on the principle of phase change refrigeration, allowing the liquid nitrogen to rapidly evaporate as it flows through the freezing head, releasing ultra-low temperatures that precisely target the diseased tissue, causing it to necrose and slough off. The entire process is a purely physical therapy, with minimal impact on surrounding healthy tissue, making it safe and highly effective.

The device is constructed of stainless steel, resistant to low temperatures and corrosion, maintaining stable performance under extreme temperature variations. The double-walled bottle design not only effectively prevents frost and condensation on the outside but also avoids the risk of the bottle bursting due to thermal expansion and contraction, greatly improving safety.

Structurally, it consists of a cryoprobe (available in 9 sizes), connecting elbows, infusion tubing, liquid nitrogen cup, cup lid, and exhaust valve. Its modular design makes assembly, cleaning, and maintenance extremely convenient. Its compact size and lightweight design, along with the included carrying case, allow medical staff to easily carry it in clinics, wards, or for external consultations, enabling them to perform treatments anytime.

Operationally, its process is intuitive and simple, requiring no complex training. Its powerful cooling effect and rapid cooling speed significantly improve clinical efficiency, making it a reliable and helpful tool in dermatology clinics.
