      The use of disposable precision metering drainage bags in wound drainage is mainly based on the consideration of correct monitoring, prevention of infection, convenient use and other aspects, as follows:
1. correctly monitor the condition
      Correct measurement: the amount of wound exudate after trauma is an important indicator to judge the healing of the wound and the change of the patient's condition. The disposable precision metering drainage bag can correctly measure the volume of drainage fluid and provide correct data for medical staff. Through the dynamic observation of the amount of drainage fluid, medical staff can timely find out whether there is abnormal bleeding and increased exudation in the wound, so as to take corresponding treatment measures.
      Observation character: in addition to the monitoring of quantity, the color, nature and odor of drainage fluid are also important clues to reflect the condition. The transparent material and clear scale of the drainage bag are accurately measured, which is convenient for medical staff to observe these characteristics of the drainage fluid at any time, and is helpful to judge whether there are problems such as infection and tissue necrosis in the wound. For example, the normal wound exudate may be a reddish bloody liquid at the initial stage of the wound, and will gradually become a clear yellowish liquid as the wound heals; If the exudate color is bright red and the amount continues to increase, it may indicate that there is active bleeding in the wound; If the exudate becomes turbid and smelly, it may mean that the wound has been infected.
2. prevention of cross infection
      Disposable use: disposable precision metering drainage bags are discarded after use to avoid cross infection caused by repeated use. Trauma patients' physical resistance is usually weak, and the wound is vulnerable to bacteria, viruses and other pathogens. The use of disposable drainage bags can effectively prevent the transmission of residual pathogens to patients due to poor cleaning and disinfection of drainage bags, reduce the risk of infection, and ensure the safety of patients.
      Good sealing: this kind of drainage bag usually has good sealing, which can prevent the leakage of drainage fluid and the entry of external bacteria. During the drainage process, the drainage bag is closely connected with the drainage catheter to form a relatively closed system, which reduces the chance of external microorganisms contaminating the drainage fluid and further reduces the possibility of infection.
3. convenient medical operation
      Easy to operate: the disposable precision metering drainage bag is reasonably designed and easy to operate. The medical staff only need to correctly install and connect according to the instructions when using, and then the drainage can be started. Its structure is usually simple, without complex assembly or debugging process, which saves the operation time of medical staff and improves work efficiency.
      Easy to carry and store: the drainage bag is small in volume, light in weight, and easy to carry and store. When the patient needs to be transported or moved, the drainage bag can be easily fixed on the patient without affecting the patient's handling. At the same time, its lightweight design is also convenient for storage and management in wards, operating rooms, emergency rooms and other different medical places.
