Answer: 1 kinds of eggs are preheated and hatched. Put the eggs on the air-conditioned egg bank into the room at 22°C to 25°C for 6 to 8 hours to remove the water vapor on the eggs. After the egg temperature reaches room temperature, the eggs are incubated in the tray.
2 control the temperature. Temperature is the primary condition for the development of chicken embryos. The temperature control during incubation should be steady, and it should be avoided. The incubation period of the chicks was 21 days: the incubation temperature was 38.5°C for 1 to 6 days, 38°C for 7 to 14 days, 37.8°C for 15 to 18 days, and 37.4°C for 19 to 21 days.
3 control humidity. By controlling the humidity, the embryos can be heated evenly in the early stage, which is beneficial to heat dissipation and clam shell hatching in the middle and later stages. Under normal circumstances, relative humidity: 60% to 70% for 1 to 7 days, 50% to 55% for 8 to 16 days, and 65% to 70% after 17 days.
4 ventilation. Chicken embryonic development must continue to exchange gas with the outside world, especially in the late post-incubation, the embryo begins lung respiration, oxygen demand increases, carbon dioxide emissions increase, then you should increase ventilation and ventilation, keep the air fresh.

Product Description
Disposable surgical medical products refer to items used in surgical operations, which are discarded after one use. These products are used to maintain a sterile environment and prevent the spread of infection during surgery.
Some common disposable surgical medical products include:
1. Surgical masks: used to cover the mouth and nose of medical staff during operations to prevent the spread of germs.
2. Surgical gowns: Medical staff wear these to protect their clothing from contamination during surgery.
3. Surgical Gloves: Healthcare providers wear these gloves to protect their hands from contamination during surgery.
4. Surgical Drape: Used to cover the patient and create a sterile field around the surgical site.
5. Surgical needles: Used to suture incisions and wounds during surgery.
6. Scalpel blades: These are used to make incisions during surgery.
7. Surgical Forceps: Used to grasp and manipulate tissue during surgery.
8. Surgical catheters: These catheters are used to drain fluids from the body during surgery.
Overall, single-use surgical medical products are critical to maintaining a sterile environment and preventing the spread of infection during surgery.
