[0027] Please refer to Figure 1-2, an anti-reflux automatic metering drainage bag provided in this embodiment includes a drainage bag body 1. A drainage port 11 is opened at the top of the drainage bag body 1, and a liquid leakage port 12 is opened at the bottom of the drainage bag body 1. A drainage tube 13 is connected to the drainage port 11. A plurality of self-sealing strips 14 are horizontally and spaced inside the drainage bag body 1, and the plurality of self-sealing strips 14 horizontally divide the inside of the drainage bag body 1 into several parts; a magnetic valve assembly 2, the magnetic valve assembly 2 includes a magnetic ring 21 and a magnetic cover 22. The diameter of the magnetic ring 21 is adapted to the caliber of the drainage port 11, the magnetic cover 22 is adapted to the magnetic ring 21, the magnetic ring 21 is installed on the drainage port 11, and a plurality of control belts 23 are evenly connected around the drainage port 11 inside the drainage bag body 1. The magnetic cover 22 is connected to the plurality of control belts 23, the magnetic cover 22 is spaced below the drainage port 11, and a floating plate 24 is arranged on the side of the magnetic cover 22 away from the drainage port 11.

[0028] Specifically, the drainage bag body 1 contains the drainage fluid. The drainage tube 13 connected to the drainage port 11 is connected to the tube inserted into the patient's body for drainage. The liquid leakage port 12 discharges the body fluid in the drainage bag body 1. A part of the self-sealing strip 14 is installed on each of the two inner surfaces of the drainage bag body 1. Medical staff and fingers outside the drainage bag body 1 press two parts of a pair of self-sealing strips 14 simultaneously to seal the self-sealing strip 14, completing the separation of the drainage bag body 1. Multiple pairs of self-sealing strips 14 are horizontally installed at vertical intervals on the drainage bag body 1. Medical staff can separate the drainage bag body 1 according to the usage requirements. When the drainage fluid continuously flows into the drainage bag body 1, the upper half of the separated drainage bag body 1 will slowly fill up with the drainage fluid. When the water line of the drainage fluid is about to reach the drainage port 11 at the top of the drainage bag body 1, the magnetic cover 22 restricted at the drainage port 11 and the floating plate 24 at the bottom of the magnetic cover 22 will be lifted up. The magnetic cover 22 is directly below the magnetic ring 21 arranged on the drainage port 11. The magnetic cover 22 rises continuously with the water level of the drainage fluid until the magnetic cover 22 covers the magnetic ring 21, indicating that the drainage bag body 1 is full and the drainage is completed; this device can also drain the middle segment urine. First, open the self-sealing strip 14, let the patient's urine flow into the drainage bag body 1, and then close the self-sealing strip 14 to continue collecting urine. The urine above the self-sealing strip 14 is the middle segment urine, which diverts the urine for the convenience of medical staff to observe. Similarly, for other special drainage fluids that need to be collected, they can also be collected in segments; this device can adjust the required drainage volume by medical staff, and then automatically close the drainage port 11 to complete the drainage when the drainage is completed, eliminating the need for medical staff to watch constantly, reducing the workload of medical staff, and being more convenient, simple, and practical to operate.

[0029] In some possible implementation manners, the magnetic cover 22 is in an inverted conical shape, the diameter of the bottom circle of the magnetic cover 22 is not less than the diameter of the magnetic ring 21, and the control belt 23 is connected to the bottom of the magnetic cover 22. An upward groove is provided at the top of the drainage bag body 1, the drainage port 11 is located at the top of the groove, and the magnetic ring 21 is located at the top of the groove.

[0030] Specifically, the inverted conical magnetic cover 22 has a pointed top and is easier to insert into the magnetic ring 21. When the floating plate 24 floats, even if there is a water level drop, the magnetic cover 22 can accurately insert into the magnetic ring 21. The bottom diameter of the magnetic cover 22 is larger than that of the magnetic ring 21, providing a more dense seal for the magnetic ring 21. The role of the groove is to provide a certain guiding effect for the insertion of the magnetic cover 22. The magnetic cover 22 floats upward along the groove and then smoothly enters the magnetic ring 21.

[0031] In some possible embodiments, there are three control bands 23, and the three control bands 23 are evenly arranged around the drainage port 11.

[0032] Specifically, the three control bands 23 can stably limit the magnetic cover 22 below the drainage port 11. When the magnetic cover 22 is suspended in the drainage bag body 1, it is more stable and will not tilt, which is more beneficial for the magnetic cover 22 to insert into the magnetic ring 21 when the water level rises.

[0033] In some possible embodiments, the capacity of the drainage bag body 1 is 1500 ml, and capacity scales are marked on the drainage bag body 1. The capacity scales are marked from top to bottom near the self-sealing strip 14 on the drainage bag body 1.

[0034] Specifically, the drainage bag body 1 with a capacity of 1500 ml has a large capacity and can meet the different needs of different patients. The capacity scales on the drainage bag body 1 help medical staff determine the volume of the drainage fluid. When the drainage bag body 1 is draining, since the volume of the drainage can be determined through the self-sealing bag, and the drainage port 11 is located at the top of the drainage bag body 1, the scales beside the self-sealing strip 14 are marked from top to bottom to determine the required drainage volume. Seal the self-sealing strip 14, and the capacity of the drainage bag body 1 above the self-sealing strip 14 is the required volume. Further, after the drainage bag body 1 receives the drainage fluid, the body of the drainage bag body 1 will bulge. It is not easy to observe the volume of the drainage fluid inside the drainage bag body 1 at the side section of the drainage bag body 1. To solve this problem, scales that can reflect the bulging volume can be marked on the drainage bag body 1 according to its bulge to support medical staff to observe more intuitively.

[0035] Furthermore, multiple labels or blank printing areas can be set on the surface of the drainage bag body 1, and medical staff can mark the responsible person, date, etc. on the labels or blank areas, which is convenient for medical staff to record the situation.

[0036] In some possible embodiments, there are five groups of self-sealing strips 14, and the five groups of self-sealing strips 14 are horizontally spaced inside the drainage bag body 1.

[0037] Specifically, the five self-sealing strips 14 start from the upper capacity scale marking of the drainage bag body 1 from top to bottom and are marked at 100 ml, 300 ml, 600 ml, 900 ml, and 1200 ml. The five self-sealing strips 14 can meet the needs of most patients, divide the drainage bag body 1, and make it more convenient for medical staff to use.

[0038] In some possible embodiments, a connector 131 is installed at one end of the drainage tube 13 away from the drainage bag body 1. A rubber sleeve 132 is sleeved at the connection between the connector 131 and the drainage tube 13, and a protective sleeve 133 is sleeved on the connector 131.

[0039] Specifically, the drainage tube 13 of the device needs to be connected to the tube inserted into the patient's body. The connector 131 is provided on the drainage tube 13, which is more tightly connected to the tube in the patient's body. When the drainage tube 13 is connected to the tube inserted into the patient's body, the rubber sleeve 132 is wrapped around the connection between the connector 131 of the drainage tube 13 and the tube inserted into the patient's body to further increase its tightness. When not in use, the protective sleeve 133 is sleeved on the connector 131 to protect the connector 131 from being contaminated by contact with the external environment.

[0040] In some possible embodiments, a snap clip 134 is installed on the drainage tube 13; a shut-off clip 121 is installed at the liquid leakage port 12.

[0041] Specifically, the snap clip 134 plays an interception role. When a special situation occurs or it is necessary to temporarily stop drainage, the snap clip 134 is used to cut off the drainage. The shut-off clip 121 at the liquid leakage port 12 also plays an interception role. When it is necessary to drain the drainage liquid in the drainage bag body 1, the shut-off clip 121 is opened to let it flow out. The shut-off clip 121 can be a snap type, which is more convenient to use.

[0042] In some possible embodiments, a hanging rope 15 is provided at the top of the drainage bag body 1.

[0043] Specifically, setting the hanging rope 15 at the top of the drainage bag body 1 allows the hanging rope 15 to be hung on an infusion stand or the head of the bed, eliminating the need to hold it by hand at all times and improving its convenience.
