Description
Medical device.
Sodium hyaluronate for intra-articular injection.
Sodium hyaluronate is a high molecular weight polysaccharide composed of sodium glucuronate and N-acetylglucosamine. Sodium hyaluronate is distributed throughout the body and is present in high concentrations in tissues such as vitreous humor, synovial fluid, umbilical cord, and dermis. Sodium hyaluronate acts as a tissue lubricant and is believed to play an important role in modulating the interaction between adjacent tissues. It can also act as a viscoelastic support, maintaining tissue separation. Different preparations of sodium hyaluronate may have different molecular weights, but they are always considered to have the same chemical structure.

How to use
Store at 2°C to 25°C. Allow to reach room temperature for approximately 20-45 minutes before use. Not for intravenous injection. The required amount is slowly injected into the selected joint space using a non-rigid, ISO/ANSI standard pivot-type hypodermic needle of the appropriate diameter. Diameters used for knee injections are 18-21 gauge. The final selection for any procedure should be determined by the physician. The volume varies depending on the size of the joint space, but should not exceed 2 ml for knees and other large joints or 1 ml for small joints. It is the physician’s responsibility to determine the appropriate volume to ensure that the joint is not overfilled. The recommended treatment regimen is 3 injections at 1-week intervals for each treatment course, with a maximum treatment course for an individual joint in a 6-month period. Remove any effusion from the joint before injecting the product. Do not overfill the joint space.

– known joint infections;
– known systemic bleeding abnormalities.
The products may contain traces of gram-positive bacterial proteins and are contraindicated in patients with a history of similar allergies.

warnings
Normal precautions for joint injections are recommended. Only healthcare professionals familiar with accepted injection techniques for administering agents into joint spaces should inject sodium hyaluronate for this application. Do not use excessive amounts of sodium hyaluronate and keep the patient under close supervision. Do not overfill the space. If pain increases during injection, stop the injection and remove the needle. If abnormalities occur after administration of the products, patients should contact their physician immediately. Do not use if the inner packaging (pouch) is opened or damaged. For intra-articular injection. Not intended for intravenous injection. Sale and use of this medical device is restricted to or under the supervision of a physician. For single use only. Do not resterilize.
