Description

Technical Field

[0001] The utility model relates to the technical field of drainage bags, in particular to a backflow-proof drainage bag. Background Art

[0002] A drainage bag is a medical device that is mainly used to collect fluids discharged from the human body, such as urine, wound drainage fluid, etc. It is usually connected to a drainage tube to drain the fluid into the bag through negative pressure suction or other means.

[0003] Since the existing drainage bag has a relatively simple structure and is not convenient to be hung and fixed on the bedside, sometimes in order to facilitate the movement of the patient, the drainage bag needs to be fixed on the patient's body. The drainage bag is close to the patient's skin and has poor air permeability. Especially when used in summer, the patient's skin sweats and the comfort is poor. The liquid in the existing drainage bag may be too high due to changes in the patient's body position or the user's carelessness, exceeding the puncture point, causing the drainage fluid to flow back, affecting the treatment effect. Therefore, it is necessary to provide a drainage bag that prevents backflow to solve the above problem. Utility Model Content

[0025] The drainage bag body 1 has a drainage head 102 disposed at the center of the lower end of the drainage bag body 1;

[0026] A drainage tube 6 is provided at the upper end of the drainage bag body 1;

[0027] A drainage joint 101 is arranged at the center of the upper end of the drainage bag body 1, an anti-backflow component 5 is arranged at the upper end of the drainage joint 101, a discharge port at the lower end of the drainage tube 6 is connected to the upper end of the anti-backflow component 5, and a side frame 3 is arranged on one side of the back of the drainage bag body 1.

[0028] Among them, fixed blocks 2 are provided on both sides of the drainage joint 101 and the drainage head 102, and the side frame 3 is fixedly connected to the fixed block 2. The fixed block 2 is provided to facilitate the fixed installation of the side frame 3. When the anti-backflow drainage bag is fixed on the patient's body, the side frame 3 can be directly fixed. The side frame 3 can limit the position of the drainage bag body 1, effectively preventing the drainage bag body 1 from sticking to the patient's skin, ensuring the air permeability between the drainage bag body 1 and the patient's skin, and improving the patient's comfort.

[0029] Among them; the upper ends of the fixing blocks 2 located on both sides of the drainage joint 101 are fixed with hanging rings 4. By providing the hanging rings 4, it is convenient to hang and fix the drainage bag body 1 on the side of the patient's bed, and when the drainage bag body 1 is hung and fixed on the side of the patient's bed, ensure that the side frame 3 faces outward. At this time, the side frame 3 can effectively protect the drainage bag body 1 and prevent the drainage bag body 1 from being damaged by friction and scratches.

[0030] Among them; the backflow prevention component 5 includes a tube body 501, a base 502 and a reset spring 503. The tube body 501 is fixedly arranged between the drainage joint 101 and the drainage tube 6. The base 502 is arranged at the lower end of the tube body 501. An opening is opened in the center of the base 502. The base 502 is provided to facilitate the installation of the reset spring 503.

By providing a hanging ring 4, it is convenient to hang and fix the drainage bag main body 1 at the patient's bedside, and when the drainage bag main body 1 is hung and fixed at the patient's bedside, ensure that the side frame 3 faces outward. At this time, the side frame 3 can effectively protect the drainage bag main body 1 and prevent the drainage bag main body 1 from being damaged by friction and scratches.

[0034] Furthermore, when the drainage fluid enters the tube body 501 through the drainage tube 6, the drainage fluid pushes the sealing head 504 and the float 505 downward under the action of the gravity of the drainage fluid, and the drainage fluid can flow down through the gap between the side wall of the tube body 501 and the sealing head 504. When the position of the drainage bag body 1 is too high, causing the liquid inside the drainage bag body 1 to flow back into the tube body 501, the buoyancy of the float 505 and the thrust of the return spring 503 push the sealing head 504 upward to contact the inner wall of the tube body 501, thereby preventing the liquid from flowing back.
