Medical Liquid Nitrogen

Applications of Medical Liquid Nitrogen:

Since medical liquid nitrogen has a very low temperature and a controlled purity, it is one of the most important medical and laboratory gases, which is used in some fields and is among the basic gases in many therapeutic and research centers. Some of these applications are:

Cryotherapy and Treatment of Skin Lesions

The most widespread role of liquid nitrogen in the medical field is the treatment of skin lesions. In this method, the doctor uses an applicator or cryo spray to carefully apply nitrogen on the injury and remove lesions such as skin warts, benign keratoses, and some stains and moles by rapid freezing of the tissue. This technique is less invasive, almost without surgical cuts, and has a relatively short recovery period.

Freezing and Preserving Bio Samples

In medical laboratories, IVF centers, and cell banks, medical liquid nitrogen is used for freezing and long-term preserving sensitive samples such as sperm, ovum, and embryos in infertility treatment, also cells and experimental tissues, some blood and genetic samples. The extremely low temperature of liquid nitrogen minimizes the biochemical reaction rates and enables sample preservation for long periods of time with minimal defects.

Applications in Specialized Processes and Advanced Treatment Methods

In some limited surgical methods and professional treatments, liquid nitrogen is used for size reduction or controlled deterioration of non-medical tissues. These applications belong to specialties like dermatology, ophthalmology, and some surgical branches, based on their protocols, and must always be under the supervision of a trained treatment team.

The most important advantages of using medical liquid nitrogen

• Extremely high refrigeration for cryotherapy and cryopreservation
• Ability to treat skin defects without open surgery and with a short recovery period
• Long-time stability of bio samples at very low temperatures
• Decreasing the need for non-invasive methods in some treatments
• Possibility of being used in laboratories, clinics, and hospitals that have suitable equipment

Constrains and Risks of Medical Nitrogen

Direct contact of liquid nitrogen with skin or eye can cause frostbite, blain, or severe injury of the tissue; so, using liquid nitrogen without sufficient protective equipment and proficiency is very dangerous. On the other hand, vapors of liquid nitrogen can reduce the concentration of oxygen in the atmosphere of confined places and increase the risk of suffocation when the air conditioning is not functioning properly. Therefore, liquid nitrogen must only be used in places that have sufficient ventilation and by following safety principles.
Medical-grade liquid nitrogen should be used only by trained professionals, such as doctors or laboratory technicians; any unauthorized use could result in severe and irreversible damage. In medical applications, liquid nitrogen should always be used in accordance with treatment and safety protocols and under the supervision of an expert. It should never be used for breathing or for direct application to a patient’s airways, which is extremely dangerous and prohibited.

Accessories and Technical Considerations of Medical Liquid Nitrogen

For the safe and standard usage of medical liquid nitrogen, special and suitable medical gas equipment should be used. This gas is stored in two-wall and insulated cryogenic reservoirs to maintain its very low temperature. Warmer, applicator, and cryo spray are used for precise and controlled application of liquid nitrogen on the injury in medical applications such as skin cryotherapy. In laboratories and IVF centers, bio samples are kept inside cryo tanks and specific racks in liquid nitrogen. Special legs and wheels are used for the transportation of these tanks in a center to prevent impacts and overturning.

Medical Liquid Nitrogen Tank

Liquid nitrogen is kept in cryogenic liquid tanks instead of in common pressurized cylinders; these tanks were designed to preserve the very low temperature of the liquid nitrogen. These tanks are supplied in different capacities, including:
• Small cryogenic tank for skin clinics and offices (mostly with some liters of capacity)
• Medium tanks for laboratories and medical centers
• Large cryo tanks for IVF centers and cell banks
Tank volume and type selection depends on the consumption and number of patients/samples.

Safety, Storage, and Transportation of Medical Liquid Nitrogen

Sufficient ventilation: Using and keeping liquid nitrogen should be done in suitably ventilated areas to prevent oxygen reduction. Personal protection: using insulated gloves, protective glasses, and a suitable suit to prevent frostbite.
Preventing gas confinement: Liquid nitrogen tanks should not be kept in confined and unventilated places (such as small rooms without a ventilator or windows).
Safe transportation: Using special wheels and suitable restraints is necessary in internal transportation. Prevent laying the tanks on the ground or direct impact on the tanks.
Avoid completely closing the stream outlet gate: the liquid nitrogen reservoir should have an exit gate to vent the vapors; never block the caps or valves that are designed for ventilation, since it increases the risk of pressure rise.
Keeping away from heat sources: The tank should be away from flames, direct sunlight, and heat sources.
