This type of anti bedsor air mattress will be with Turn over and toilet functions. More comfortable for the patients and lesser labour taking for the nursing people.Dynamic mattress overlays utilize a power source to constantly alter the level of support, while static overlays reduce pressure by spreading the user`s weight over a larger area through the use of consistent inflation. All hospital bed overlays are intended to increase comfort for patients and help reduce the constant pressure on bony prominences of the body, as it is this constant pressure that leads to the development of pressure ulcers.

Do not forget the winter wheat at nine o'clock in winter
Winter wheat from the emergence to winter, fertility characteristics are long-rooted, long-leaved, long-term tillering, complete vernalization stage, that is, "three-year-long completion", the growth center is childbirth. The central task of field management is to build on the basis of conservation of seedlings, promote root growth, make weak seedlings grow stronger, and strong seedlings grow steadily to ensure that the wheat seedlings safely pass through the winter, laying a good foundation for the panicles and spikes in the coming year. First, check seedlings replant. Due to leakage of seed, lack of earthworms, underground pests and other reasons, resulting in lack of seedlings broken ridge, timely seedling reseeding, will replant the wheat seed soaked in cold water for 24 hours after drying to ensure that seedlings are seedlings uniform. Second, to eliminate seedling pests and diseases. The common seedling pests are earthworms, planthoppers, underground pests, and leaf rust. Third, overwhelming the needle. When wheat enters the three-leaf stage, the nutrients in the endosperm of the seed are exhausted. The seedlings must rely on their own photosynthesis to produce nutrients, which is a crucial period for promoting root growth. Overwhelming the needle is a powerful measure, that is, repressing it at the three-leaf stage to control the main stem, promote the delivery of tinea, control the ground and promote the role of the root system. Fourth, scratch wheat soil. In case of rain during the tillering period, the wheat slush should be scratched in time to help remove the compaction and promote root growth. For Wang Miao, deep scratch (more than 7 cm), can play a role in root control. Saline-alkali wheat should be washed after rain and prevent back-salt from harming wheat seedlings. Fifth, pouring good winter water. Winter irrigation should be timely, generally begin at an average temperature of 7-8 °C, to about 5 °C, the end of the winter irrigation should not be too large, the day can be suitable for infiltration, avoid flood irrigation. For the lack of basic seedlings or early sowing of defermented rice seedlings or wheat without adequate base fertilizer, combined with winter fertigation, 5-10 kg of urea per mu, prompting the early return of wheat to green, consolidate tiller before winter, increase tiller rate, so that Winter fertilizer used in spring. 6. Pouring urine in winter. Overwintering before returning to the spring can be poured with urine, with the plot with the pouring, generally about 500 kg of urine per acre, saline or alkali wheat fields when there is snow should not pour urine, pouring urine production effect is significant, about every application of 15 kilograms of fresh urine can increase production 1 kg. 7. The cover is protected against cold and seedlings. After wheat enters the overwintering period, prematurely, it will yellow the wheat seedlings; too late, the leaves will be frozen and the operation will be difficult. After the winter irrigation, on the basis of the recalcitrant soil, bamboo shoots were used to cover the seedlings on the bamboo shoots in the Daxing Zhongrong, and the cover soil was about 2 cm. This technical measure can stabilize the temperature, reduce the evaporation of soil moisture, ensure that the wheat is green over winter, reduce the cracking of the ground, and make up for cracks. Eight, rolling pressure. The repression cover is rolled 1-2 times before it is returned to green, and it is crushing and rubbing the waste to make the soil fine and compact. This will help eliminate compaction, cracking, heat preservation, and can be used to prevent soil leakage. This is another important means of drought resistance and cold-preserving seedlings. 9. It is forbidden to graze the barley in wheat fields. The green leaves that remain during wintering can be used for photosynthesis after returning green. It is the main source of nutrients needed for fresh growth. Winter grazing will cause a lot of damage to this part of the green area, weakening the ability to resist cold and reducing yield.
