After the cuttings are collected, they should be stored in the ditch in time. Before entering the ditch, they should be soaked in 100 times the new high-fat membrane to avoid mold deterioration during storage, moisture evaporation, infection prevention, freeze-resistance, and germination.
The storage ditch should be selected where the terrain is high, the drainage is good, the groundwater level is low and the shade is cloudy. The ditch is 1 meter deep and 1 to 1.5 meters wide. The ditch length depends on the number of cuttings, usually 10 meters. After the ditch is dug, a layer of 10 cm thick clean wet sand is laid on the bottom of the ditch, and the cuttings are bundled in a sequence of bales and bales, and the bales are separated from the bales by fine sand. After laying down one layer of cuttings, a layer of 10 cm thick wet sand is laid and the gaps in the cuttings are fully filled to prevent freeze-drying. Usually put 2 to 3 layers on the line. Another way is to put the cuttings obliquely into the ditch. The cuttings are also filled with wet sand. Finally in the rows of soil covered 20 to 30 cm, sprayed 800 times the new high-fat film can protect the water vaporization, evaporation, sun drought, insulation, antifreeze, anti-soil compaction, suffocation and isolation of pests and diseases. The roof of the trench is ridged to facilitate cold protection.
The temperature in the ditch should be maintained at about 1°C, and it must not be higher than 5°C or lower than -1°C. The sandy soil of the cuttings should maintain a humidity of 70% to 80%. When the temperature of the ditch is close to 7 to 8°C, when the cuttings have a fever phenomenon, the ditch should be turned back in time to thin the cover soil. When it is too dry, it can be sprayed with an appropriate amount of fresh water.
For medical or medical disinfection and sterilization, suitable sterilization methods include EO ethylene oxide sterilization, steam high temperature and high pressure steam moist heat sterilization, and gamma cobalt 60 irradiation sterilization. Its use method and effect: medical devices are packed into packaging bags and then sealed for sterilization and disinfection. The packaging bags are used to pass sterilization factors and do not pass through the semi-dialysis permeability of bacteria, and then the professional institution Soochow University Medical Testing Institute conducts EN868 After professional testing, it is shown that the aging of the packaging bag can reach 3 to 5 years. Objects: medical gloves, medical syringes, hemostatic gauze, surgical hole towels, medical catheters and tracheal intubations, surgical gowns, intravascular catheters, indwelling needles, electrosurgical pens , Heparin cap, three-way stopcock, roar cover, balloon, artificial joint, occluder and other medical consumables packaging and high-end medical equipment packaging.
