[0002] A drainage bag is a medical device. After a patient undergoes surgery, blood clots and other solids in the body or deep in the local surgery need to be drained through a pipeline. A transparent plastic bag specifically for holding the drained liquid is connected to the end of the drainage tube, which is also called a drainage bag.

[0003] However, in the process of using the existing drainage bags, solid substances such as blood clots in the drainage fluid are likely to block the drainage outlet of the drainage bag, which is not conducive to the normal drainage of the drainage bag. The existing drainage bags are divided into hanging type, arm hanging type, etc. The application scenarios of each drainage bag are single. The hanging type has a limited range of activities, and the wall-mounted type is easily squeezed when the patient is in bed, with a small scope of application. In order to solve the deficiencies of the existing technology, we propose a drainage bag with a filter structure. Summary of the Utility Model

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1-3 shown, a drainage bag with a filter net structure includes a drainage bag main body 1. A sealing strip 2 is detachably installed at the top of the drainage bag main body 1. A movable belt assembly 3 is arranged outside the sealing strip 2. When a patient needs to hang the drainage bag main body 1, the medical staff pulls the first movable belt 6 towards the front of the drainage bag main body 1. The first movable belt 6 drives the first limit blocks 7 at both ends. The first limit blocks 7 drive the fixed block 5. The fixed block 5 drives the sealing strip 2 to drive the drainage bag main body 1. Hang the first movable belt 6 on the hook at the patient's bed, so as to hang the drainage bag main body 1. When the patient needs to move, the medical staff removes the hanging drainage bag main body 1, and then pulls the first limit block 7 at one end of the first movable belt 6 towards the back of the drainage bag main body 1, and pulls the second limit block 10 at the symmetric end of the second movable belt 9 and the first movable belt 6 towards the back of the drainage bag main body 1. The other ends of the first movable belt 6 and the second movable belt 9 are limited at the fixed block 5 by the same first limit block 7 and second limit block 10. Surround the first movable belt 6 and the second movable belt 9 outside the patient's arm. The second movable belt 9 is placed outside the first movable belt 6. Then pass the adjusting belt 8 on the first movable belt 6 through the limit opening 11 on the second movable belt 9. The first movable belt 6 and the second movable belt 9 closely fit the outside of the patient's arm. Then insert the convex block 12 on the second movable belt 9 into the current limit hole of the adjusting belt 8. The convex block 12 cooperates with the adjusting belt 8 to fix the first movable belt 6 and the second movable belt 9 outside the patient's arm, so as to bind the drainage bag main body 1 outside the patient's arm. The drainage bag main body 1 is switched between a hanging type and an arm hanging type through the second movable belt 9 and the first movable belt 6, which is convenient for the patient to use, and the application range of the drainage bag main body 1 is wider.

[0023] As Figure 2 and Figure 4As shown, a drainage tube 17 is connected through the top of the sealing strip 2. One end of the drainage tube 17 is detachably installed with a connector 18. A drain pipe 19 is connected through the bottom of the drainage bag body 1. A drain valve 20 movably penetrates through one side of the drain pipe 19. A through hole is opened on one side of the drain valve 20. A filtering component 4 is arranged inside the drainage bag body 1. When the drainage bag body 1 needs to be used, the connector 18 is connected to the part of the patient that needs drainage by medical staff. The liquid such as the accumulated fluid in the patient's body is drained into the drainage bag body 1 through the cooperation of the connector 18 and the drainage tube 17. After the drainage fluid enters the drainage bag body 1, it passes through the first filter screen 13. The first filter screen 13 filters and intercepts the solid substances with a relatively large diameter in the drainage fluid, such as blood clots. The triangular first fixing strip 14 guides the sediment to preferentially accumulate on both sides of the first filter screen 13, facilitating the continuous filtration of the drainage fluid. The preliminarily filtered drainage fluid passes through the first filter screen 13 and enters the second filter screen 15. The second filter screen 15 filters and intercepts the smaller solid substances and flocculants in the drainage fluid. The wavy second fixing strip 16 guides the sediment of the secondary filtration to preferentially accumulate at the lower part of the wave shape, facilitating the drainage fluid to enter the bottom of the drainage bag body 1. After the drainage fluid passes through the secondary filtration, it enters the bottom of the inner wall of the drainage bag body 1 for storage. When the storage reaches a certain amount, the medical staff pushes the drain valve 20, and the through hole of the drain valve 20 is aligned with the inner hole of the drain pipe 19, and the drainage fluid is discharged from the drain pipe 19. Through the cooperation of the first filter screen 13 and the second filter screen 15 for two - stage filtration, the filtration effect is better, preventing the solid substances in the drainage fluid from blocking the drain pipe 19 and facilitating the drainage of the drain pipe 19.

[0024] Working principle

[0025] It should be noted that the present utility model is a drainage bag with a filter net structure. When in use, first, medical staff connect the connector 18 to the part of the patient that needs drainage. The liquid such as the body fluid in the patient flows through the connector 18 and the drainage tube 17 into the drainage bag main body 1. After the drainage fluid enters the drainage bag main body 1, it passes through the first filter net 13. The first filter net 13 filters and intercepts the solid substances such as blood clots with a larger diameter in the drainage fluid. The solid substances in the first filter net 13 fall onto the first fixing strip 14 which is triangular at the bottom of the first filter net 13 when depositing. Under the guidance of the triangular shape of the first fixing strip 14, the sediment accumulates preferentially on both sides of the first filter net 13, reducing the sediment at the center of the first filter net 13, and creating a space for the drainage fluid to flow out through the convex part at the center of the first filter net 13, facilitating the continuous filtration of the drainage fluid. The preliminarily filtered drainage fluid passes through the first filter net 13 and enters the second filter net 15. The second filter net 15 filters and intercepts the smaller solid substances and flocs in the drainage fluid. The bottom of the second filter net 15 is formed by the second fixing strip 16 with a wavy shape to guide the sediment of the secondary filtration to deposit. The sediment accumulates preferentially at the lower part of the wavy shape, reducing the sediment at the top of the wavy shape, and facilitating the drainage fluid to enter the bottom of the drainage bag main body 1. After the drainage fluid passes through the secondary filtration, it enters the bottom of the inner wall of the drainage bag main body 1 for storage, realizing guiding the sediment to reserve a filtration space, facilitating the filtration of the drainage fluid, and ensuring the filtration efficiency.

[0026] When the connection between the drainage bag main body 1 and the patient is completed and it needs to be hung, pull the drainage bag main body 1, and pull the first movable belt 6 or the second movable belt 9 towards the front of the drainage bag main body 1. The first movable belt 6 drives the first limit blocks 7 at both ends. One side of the first limit block 7 is abutted and limited by the fixed block 5. The first limit block 7 drives the fixed block 5, and the fixed block 5 drives the sealing strip 2 to drive the drainage bag main body 1. Hang the first movable belt 6 on the hook at the patient's bed to complete the hanging. When the patient needs to move, remove the hanging drainage bag main body 1, pull the first limit block 7 at one end of the first movable belt 6 towards the back of the drainage bag main body 1, and pull the second limit block 10 at the symmetric end of the second movable belt 9 and the first movable belt 6 towards the back of the drainage bag main body 1. The other ends of the first movable belt 6 and the second movable belt 9 are limited by the same first limit block 7 and second limit block 10 at the fixed block 5. Surround the first movable belt 6 and the second movable belt 9 around the outside of the patient's arm. Place the second movable belt 9 outside the first movable belt 6. Pass the adjusting belt 8 on the first movable belt 6 through the limiting opening 11 on the second movable belt 9, and then closely fit the first movable belt 6 and the second movable belt 9 to the outside of the patient's arm. Insert the convex block 12 on the second movable belt 9 into the current limiting hole of the adjusting belt 8. The convex block 12 cooperates with the adjusting belt 8 to fix the first movable belt 6 and the second movable belt 9 on the outside of the patient's arm. The first movable belt 6 and the second movable belt 9 drive the fixed block 5 to drive the sealing strip 2, and the sealing strip 2 drives the drainage bag main body 1, so as to fix the drainage bag main body 1 on the outside of the patient's arm, realizing the switching between the hanging type and the arm hanging type, and having a wider scope of application.

[0027] When the drainage fluid is stored to a certain amount, the drainage valve 20 is pushed. The through hole of the drainage valve 20 is aligned with the inner hole of the drainage pipe 19, and the drainage fluid stored at the bottom inside the drainage bag body 1 is discharged from the drainage pipe 19. When the drainage amount is sufficient, the drainage valve 20 is pushed, and the drainage valve 20 blocks the inner hole of the drainage pipe 19 again, and the drainage pipe 19 stops draining, completing the drainage.
