Freshly harvested pearls often come with seawater, bodily fluids, and dirt on their surface. If left unprocessed for too long, the gelatinous calcium carbonate and organic substances on the pearl’s surface can harden, leading to darkening, oxidation, and a decline in overall quality. Therefore, it's essential to process them as soon as possible after harvesting.
(1) General Cleaning
The first step is to soak the freshly collected pearls in fresh water immediately. Afterward, wash them using mild soap and clean water, then gently wipe them dry. To ensure all mucus and impurities are removed, you can soak the pearls in saltwater for 5 to 10 minutes, followed by a gentle rub with fine salt. The ratio of pearls to salt should be about 2:1. Rinse thoroughly with soapy water and clean water several times, then pat them dry with a soft cloth or flannel. Store them in a cool, dry place once completely dry.
(2) Medicinal Cleaning
For lower-quality pearls, a solution of 0.15% to 0.2% sodium dodecyl sulfate can be used. After soaking, rinse well with water and store them properly.
If the pearls have a dull appearance or surface imperfections, a 3% hydrogen peroxide solution can help restore their luster. After treatment, rinse thoroughly with water and allow them to air dry before storage.
It's important to note that medicinal pearls should not be exposed to strong chemical agents. They should only be cleaned with clean water and brine to maintain their natural properties.
Once all cleaning and drying steps are complete, store the pearls in a clean, breathable cloth bag, and keep them sealed in a cabinet or drawer. Avoid exposing them to heat or direct sunlight, as this can damage their delicate structure and color. Proper storage ensures the pearls retain their beauty and value over time.
Radial Artery Compression Devices
Radial artery compression devices, also known as radial artery compression devices or wristbands, are used to achieve hemostasis after a transradial cardiac catheterization procedure. The device is applied to the wrist and inflated to compress the radial artery, which is the artery that supplies blood to the hand and fingers. This compression helps to prevent bleeding and hematoma formation at the site of the catheterization.
Radial artery compression devices are preferred over traditional compression methods such as manual compression because they are more effective, comfortable for the patient, and allow for earlier ambulation and discharge. They also reduce the risk of complications such as radial artery occlusion and nerve injury.
In addition to cardiac catheterization procedures, radial artery compression devices may also be used after other procedures that involve the radial artery, such as transradial access for arterial blood gas analysis or for the placement of intra-arterial lines.
