Usage and precautions for drainage bags

1. Method of use:
The drainage bag must be used in conjunction with a drainage tube. Firstly, after the drainage tube is properly fixed, the bleeding tube should be clamped with hemostat to stop the flow operation. This step is like closing the valve of fluid flow, preventing unnecessary contamination caused by the outflow of drainage fluid in subsequent operations. Next, the port of the drain tube is separated, which should be done carefully to avoid damage to the port. After separation, the drain tube interface is placed upwards on a clean treatment towel, which helps to prevent external contaminants from flowing into the drain tube. The interface is then sterilised using Amyl iodine, which should be thorough and complete to ensure that the interface is in a sterile state. Afterwards, open the drainage bag and remove the cap from the drainage port, and carefully connect the drainage tube port to the drainage bag port, making sure that the connection is tight to prevent leakage. After the connection is completed, use pins to fix the drainage bag in a suitable position, which can avoid the drainage bag shaking or shifting. At the same time, it is important to mark the date, which will help healthcare workers to keep track of when the drainage bag should be replaced. Ordinary drainage bags need to be replaced every day, while anti-reflux drainage bags can be replaced every 2 - 3 days. This is because anti-reflux drainage bags are designed with certain special features, which can effectively prevent reflux of drainage fluid within a certain period of time, so the replacement cycle is relatively longer. In the whole operation process, each step is closely linked, as the links in the chain, indispensable.

2, precautions:
When using the drainage bag, the disinfection link is crucial, and the principle of aseptic operation must be strictly followed. From the disinfection of the drainage tube interface to the hand hygiene during the entire operation, any small negligence may lead to bacterial infection, which in turn affects the patient's recovery process. Once the drainage bag is accessed, the tube should be carefully checked and squeezed to ensure smooth drainage. This is just like checking whether the water pipe is clogged or not. If the drainage tube is not smooth, the drainage fluid cannot be discharged properly and will accumulate in the body, which may lead to various complications. During use, it is important to pay close attention to the colour, nature and volume of the drainage fluid, which can provide healthcare professionals with important information about changes in the patient's condition. For example, a sudden change in the colour of the drainage fluid to red and an increase in its volume may indicate bleeding; if the drainage fluid becomes turbid, it may indicate the occurrence of infection. It is also important to keep an eye on the skin around the drainage opening to see if there is redness, swelling or oozing, which can be an important basis for determining whether there is an infection or allergy. In addition, it is important to keep the drainage bag lower than the drainage site at all times, as gravity is used to ensure that the drainage fluid flows smoothly into the drainage bag. The drainage bag and tube should be properly secured to avoid twisting, bending or slipping of the tube. If the drainage bag with negative pressure is used, special attention should also be paid to ensure that the drainage bag is under negative pressure, and to keep the negative pressure in the right place, as too high a pressure may cause damage to the surrounding tissues, and too low a pressure may affect the drainage effect.

In conclusion, the correct use of drainage bags and strict adherence to the precautions is an important measure to protect the drainage effect and maintain the health of patients.
