Of the total bank, which holds the leeches in a small vessel with a capacity of 50-100 ml is taken multiple instances in an amount slightly larger than that required for other purposes. Otsazhivayut leeches only need your hands or small nets for aquarium fish, not a pair of tweezers to the selection they are not damaged. It is necessary to ensure good quality of each of the leeches on the following grounds:
1) the presence of a pronounced reflex contraction (when you touch the body leech becomes short, thick, firm and dense);
2) the desire to crawl out of the vessel;
3) Activity: if the bank lowered his hand, leeches immediately clung to her and begin to bite.
If the body leech becomes knotty, or on the surface it appears ulcers, or it becomes soft and osliznevaet – then leech sick. In such cases, it must be quickly removed from the vessel and change the water. Patients use leeches in any case impossible. Immediately prior to staging leeches should be prepared boiled tweezers and tray, bottle with alcohol or hydrogen peroxide, a container of hot boiled water, sterile swabs, wipes, sticks with cotton wool and dressing (bandage, cotton). Before the procedure, the skin should be treated not only that site, which will be put leeches, but around him, shave the hair, skin, wipe with alcohol or hydrogen peroxide, and then rub vigorously with sterile cotton wool soaked in hot water, changing tampons 2-3. Use detergent odorants (soap, shampoo) in any case impossible. Thus, on the one hand, is achieved by removing the disinfectant, and on the other -vyzyvaetsya blood flow to the skin, which becomes warm, and leech readily clings thereto. If not leech clings to the warm and clean skin of the patient, it should be replaced by another, as it does not exclude the possibility that she was ill. After the treatment, the skin is necessary to move one of the leeches in a glass or tube, which is tightly put to the skin and wait for the leech prisosetsya and will undulate in front of her body. At this point, you need to release the leech of the vessel placed under its rear sucker thin layer of sterile gauze or a bandage. Attaching the patient back sucker lowers the activity of sucking. Then take the next leech. Healthy blood leech nasasyvayut period of from 30 minutes to 1.5 hours, after which there is no self-specifically in the substituted lotochek where blood flows well. Sometimes the movement of the body sucking leech stop or slow down ahead of time and it seems to be “asleep.” Then we have along her body several times to hold cotton wool soaked in warm water, after which it will resume actively suck. If a leech, not sucked the blood, there is no – then it is defective and apply it again should not be.
