Custom size medical incision protectors are medical devices specially designed to protect surgical incisions from external contaminants and mechanical damage. They are designed to fit snugly over the incision area and provide a barrier against bacteria, fluids, and other harmful substances that could lead to infection.
Custom sized medical incision protectors are commonly used in a variety of surgical procedures, including orthopedic, cardiac, and plastic surgery. They are an important tool in preventing postoperative infection and ensuring optimal healing outcomes for patients.

To create custom-sized medical incision protectors, medical professionals use advanced 3D scanning and printing technology to create an exact mold of the patient's incision area. This mold is then used to create a custom incision protector that perfectly fits the patient's unique anatomy.
These devices are usually made of medical-grade silicone or other biocompatible materials that are safe for use in the human body. They are easy to apply and remove, and can be reused many times.
A simple breeding technique for earth elements
(I) Feeding Soil (Litter) Soil is the place for the growth, development, and reproduction of earth elements. It can provide part of the water and nutrients. Therefore, the selection and preparation of the soil for raising are very important for the success of the earthen animals. Feeding soil requires looseness, fertility, and moisture. Rubbish soil is generally used. Fermented cow dung or vegetable garden soil can also be used. The cultivating soil shall be sterilized by sunlight and sieved with a 6-mesh sieve to remove impurities. For each 100 kilograms of soil, 2 kg of weathered lime powder may be added to increase the calcium content to supplement the calcium consumed by the earth pupa eggs. Adding plant ash, chaff, sawdust, and fermented manure in the rearing soil can increase the looseness and fertility of the soil. The moisture of the cultivating soil is controlled by the hand and the mixture is released. The water content is 15% to 20%. It is advisable that excessive or low water content is not conducive to the growth and development of the earth element. The thickness of the rearing soil increases with the age of the worm. Generally, the thickness of the grazing soil for young nymphs is 7-10 cm, that of medium nymphs 15-20 cm, and that of large nymphs or adults is 30 cm or more. (2) The feed soil is miscellaneous, and there are many types of feed. The main concentrates are wheat bran, rice bran, various oil cake residues, bean curd residue, etc.; green feed includes all kinds of leaves, rind, peel, vegetable stems and leaves, and mulberry, Yang, willow leaves, etc.; animal feed such as pigs, cattle, sheep, chickens, ducks, fish and other waste leftovers and scorpion. (III) Management Technology Egg hatching: The removed egg sheath is incubated in an incubation cylinder (or pool). The egg sheath is first sterilized with potassium permanganate 5000 times for 1 minute after disinfection and dried. The incubating soil is also first disinfected with benzalkonium chloride 1000 times solution and dried for use. The ratio of soil to eggs at hatching is 1:1. The soil moisture content is 25% to 30%, and the temperature is 22 to 32°C. During the incubation period, the temperature and humidity require slight differences before and after, and the temperature and humidity in the previous period are slightly lower, and the later period is slightly higher. 2. Feeding density: Tuyuanxi group living, can be high-density feeding, but the breeding density can not be too high, generally should be based on the worm age, feeding density per square meter: 1 to 3 instar nymphs is 6000 to 10000; 4 to 6 years old It is 3000 to 5000; 7 to 9 instars are 1500 to 2000; 10 to 11 instars are 1000 to 1100; and species are 400 to 500. 3. Feed feed? Feed should be "green fine with, mainly to blue." Feeding time should be in the evening, pick a variety of clean fresh leaves, leaves and bran, and evenly spread into the pool or box for the earth to eat freely. The crude material was fed once a day for 4 days, and the concentrate was once for 7 days. Concentrate enough to eat enough. Also need to feed all kinds of peel, melon and other juicy feed. Due to the different ages of the worms, the feeding depth and the depth of the soil layer are different. Therefore, the method and amount of feeding are also different. 1 to 2 instar nymphs on the surface of the soil to find food, can be sprinkled in the surface soil, biased around the pit, after 2 years of age can be added to green feed, more than 5 instar nymphs unearthed food, you can sprinkle a layer of rice husk in the surface of the feed soil. , And then spread plastic cloth or wood board, place fine material on it. 4. Detasseling: Adult males cannot be used as medicine. Males are the last few instar nymphs that have not grown into wings. In breeding, males generally account for 30% of the total number of insects, and as long as 5% of males can maintain mating needs. Therefore, when most of the nymphs develop to 7-8 years of age, excess male nymphs can be picked and treated as medicine. 5. Collection of egg sheaths: The earth element has the habit of self-eating egg sheaths, especially in the case of insufficient feed, which can cause a large loss of egg sheaths. Therefore, the egg sheath should be removed timely and incubated in the incubation cylinder (or pool). The egg sheath is usually collected every 15 days. When collected, the adult can be screened out with a 2 mesh screen, and the egg sheath can be screened out with a 6 mesh screen. 6. Pest control: Earth enemy predators include animal hazards and diseases. Animal hazards include ants, cockroaches, whiteflies, spiders, mice, hippocampus, frogs, and poultry such as chickens and ducks, of which mice are the most dangerous, followed by ants and whiteflies. Keep the mouse in the breeding room. When the ant is harmful, the fried wheat bran, bean flour and a small amount of trichlorfon can be used to trap and kill. In case of serious damage to whiteflies, 30% triclosan can be sprayed or the soil replaced. The main diseases are all kinds of mildew. In the case of high temperature and high humidity, such as poor management of soil yuan prone to mildew, the disease and the body surface dull, abdominal dark green, sluggish operation, no feeding, until a large number of deaths. Control methods: Immediately remove pests and worms and replace mud; Use 1% to 2% formalin to spray pests, and use 0.1% chloramphenicol, chlortetracycline, and oxytetracycline to mix rice bran to feed.
