Problems solved by technology

Although the invention has a good analgesic effect, the preparation method is complicated, the cost is high, the anti-inflammatory effect is general, and the wound is easy to cause infection
[0006] In summary, most of the sprays used for analgesic effect in the prior art have complex components and preparation processes, but they cannot provide long-lasting analgesia, and the drug components in the spray are difficult to be absorbed by the human body, and cannot treat damaged epidermal tissue. It has a good repairing effect, and has antibacterial and anti-inflammatory effects, which is more irritating to the human body

Abstract

The invention belongs to the technical field of aerosol for medical preparations, and particularly relates to frozen analgesic aerosol and a preparation method thereof. The frozen analgesic aerosol isprepared from the following components in percentage by weight: 40.0 to 70.0% of propellant, 22.2 to 56.0% of solvent, 0.5 to 1.8% of transdermal enhancer, 2.0 to 3.5% of analgesic and 1.5 to 2.5% ofskin tissue repair agent. The frozen analgesic aerosol provided by the invention has a good analgesic effect, is fast to absorb by a human body, can achieve long-duration analgesia, is convenient tocarry, and is suitable for using when accidents happen in sports, travelling, living or working, skin damage tissues can be repaired, infection can be prevented, swelling and pain can be relieved, andthe frozen analgesic aerosol can be used for treating sports injuries and acute arthritis.

Description

technical field [0001] The invention belongs to the technical field of aerosols for medical preparations, and in particular relates to a frozen analgesic aerosol and a preparation method thereof. Background technique [0002] Sports injury refers to the anatomical damage or physiological disorder of human tissues or organs caused by mechanical and physical factors during and after exercise. It is generally divided into two types: acute injury and chronic injury. Acute injuries include joint sprains, muscle strains, ligament strains, soft tissue contusions, skin abrasions, joint dislocations, etc. Chronic injuries include arthritis, bursitis, etc. [0003] Among them, acute arthritis refers to the infection caused by suppurative bacteria in the joints, and the clinical manifestations are redness, swelling, heat, pain, dysfunction and joint deformity of the joints. More than 85% of the common pathogens are Staphylococcus aureus. Most of the routes of infection are hematogeno...
