A vacutainer blood collection tube is a sterile glass or plastic tube with a closure that is evacuated to create a vacuum inside the tube facilitating the draw of a predetermined volume of liquid. Most commonly used to collect blood samples in venipuncture, they are also used as urine collection tubes and as serum separator tubes. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing. Tubes are available with or without a safety-engineered closure, with a variety of labeling options and closure colors as well as a range of draw volumes.
A vaccine refrigerator is a refrigeration unit designed specifically for storing vaccines and other temperature-sensitive medical supplies, most of which need to be held at temperatures lower than that of a conventional fridge. The unit provides extremely stable low temperatures to prevent degradation of vaccines and other products, along with options like alarms and backup power to provide complete protection. In the report we mainly calculated the refrigerator range from 2°to 8°.
Elastic stockings are the medical equipment which is made of a material that has a very high elasticity. Elastic stockings can deliver a distributed amount of compression at the ankle and up the leg and help relieve symptoms and slow the progress of varicose veins. They are designed to gently squeeze the legs, which promotes good blood flow in the veins. Patients with venous disease may benefit from wearing elastic stockings even if they have not recently undergone scleratherapy treatment for varicose veins.
Breast implants are medical devices that are implanted under the breast tissue or under the chest muscle to increase breast size (augmentation) or to rebuild breast tissue after mastectomy or other damage to the breast (reconstruction). Breast implants are also used in revision surgeries, which correct or improve the result of an original surgery.
