The principle of negative pressure adsorbs the drainage fluid inside the drainage tube into the drainage ball. When the negative pressure inside the drainage bulb disappears, the collection of drainage fluid is completed. In this way, the traditional medical staff directly replaces the drainage with a syringe. The method of extracting from the bag can avoid the distortion of inspection results caused by lax disinfection, which is not conducive to guiding doctors in clinical medicine. At the same time, this method is also conducive to the timely collection of specimens, and there will be no need to collect the patient's drainage bag.

This structure has low cost and is suitable for mass production;

2. In the present invention, a bellows tube is arranged between the drainage ball and the auxiliary drainage tube. The material used for the bellows is the same as the material used for the drainage tube. If the negative pressure is too low, the drainage liquid will fill the entire drainage ball. At this time, the bellows can be manually stretched to increase the volume of the drainage ball and the bellows to avoid affecting subsequent transportation and collection. There are plugs, which can block the auxiliary drainage tube and the drainage ball after the drainage ball collects the drainage liquid, so as to prevent the drainage liquid inside the drainage ball from contacting with the outside air, resulting in distorted inspection results and affecting the doctor's judgment of the disease. At the same time, a base is fixed at the bottom end of the drainage ball. The base is made of transparent rubber, which can support the drainage ball after the drainage ball collects the drainage fluid, preventing the drainage ball from tipping during the transportation process and causing drainage fluid. The possibility of omission is convenient for the transportation of the drainage ball. A storage bag is arranged on the surface of the drainage bag, and the storage bag is helpful for the placement of the drainage ball and is convenient for medical staff to organize.
