When we go to the hospital to see a doctor or check the body, it is inevitable that we need to get injections, infusions or blood tests.
The reason why many people do not like to get injections is that on the one hand, the process will be accompanied by pain, and the bleeding symptoms that accompany the needle after the needle is also an important reason.
For ordinary people's bleeding after needle, it is not a big deal, because after a while, the coagulation factors in the body begin to play a coagulation function and stop the bleeding.
However, for those with coagulation dysfunction, such as hemophilia, diabetics, etc., the continuous bleeding situation may cause serious other problems. A new recent study promises to address this vexing problem.
Medical researchers in South Korea cover the surface of medical needles with a layer of polymer compounds modified with phthalcinol.
Previous studies have confirmed that chitosan has a good coagulation function, and the key chemical structure that causes the extremely strong adhesion ability of sea shells is catechol, and researchers hope that it can help chitosan better adsorb on the surface of the needle.
The researchers then treated the needle covering chitosan at 4 degrees Celsius for a period of time so that the phthalone structure was partially oxidized, allowing them to form a mild cross-linked structure.
Through the animal experimental method of medical research, the needle covered with chitosan is used to pierce the vein of the mouse and then pull it out, and the chitosan on the surface of the needle quickly forms a gel when it encounters blood, and the hole caused by the needle puncture is sealed, thus avoiding the occurrence of bleeding.
In contrast, after the untreated needle pierced the vein of the mouse, the bleeding state lasted for a period of time before stopping.
The researchers then conducted medical experiments on mice with coagulation dysfunction, and the results were equally encouraging: mice that had been punctured by ordinary needles died of persistent bleeding, while mice that had been punctured by needles covered with chitosan had coagulation function and were unharmed.
Medical researchers believe that this new type of needle will have considerable application value in clinical use.
Puncturing the veins of mice with coagulation dysfunction with a normal needle triggers persistent bleeding,
After puncturing a vein with a needle covering chitosan, the bleeding soon stops.
The coagulation function of chitosan has long been confirmed by scientists, in addition to the application of medical needles, then the latest patented technology of disa Group, one of the top 100 companies in the pharmaceutical industry, has launched two toothpaste and mouthwash products: chitosan-rich gum toothpaste, healthy toothpaste and healthy mouth water.
Gum toothpaste contains the patented active ingredient of deep-sea crustacean biological extracted by the national patent technology: carboxymethyl deacetylacylated chitosan, and the toothpaste contains the patented active ingredient: carboxymethyl chitosan. Mouthwash contains not only carboxymethyl chitosan, but also the bacteriostatic component Dumifen, which inhibits E. coli and Staphylococcus aureus.

These two toothpaste and mouthpiece products have obvious effects on the long-term use of the following oral problems:
1. Red and swollen gums and inflammation: before brushing, soak the brush head with about 35 ° c of warm water and squeeze the toothpaste for 1-3 minutes, apply the toothpaste on the toothbrush to the corresponding position, and gently brush off with the toothbrush.
2. Ulcer: first apply the toothpaste on the toothbrush to the corresponding part, then brush other parts, and finally use the toothbrush to gently brush off the application area.
3. Frequent bleeding gums: when brushing teeth, use the vertical brushing method, apply toothpaste to the corresponding bleeding site, brush other parts, and finally use a toothbrush to gently brush off.
4. Bad breath and odor: brush your teeth in time after eating as much as possible, and appropriately extend the brushing time. In addition, it is inconvenient for workers to brush their teeth after lunch, you can contact to understand the mouthwash rich in chitosan ingredients, one at a time, which is convenient and easy to bring. Toothpaste + mouthwash comes standard.
5, cold, hot, sour, sweet discomfort: use warm water to brush teeth, first use toothpaste to apply to the uncomfortable part, and finally use a toothbrush to gently brush off the uncomfortable part.
