Description

Technical Field

[0001] The utility model relates to a drainage bag used during ICU surgery, in particular to a drainage bag used during ICU surgery, and belongs to the technical field of medical equipment. Background Art

[0002] A drainage bag is a transparent plastic bag attached to the end of a tube to collect the fluid after surgery, draining away bleeding or fluid from deep within the body or a localized area. Commonly used drainage bags are disposable and are used to collect fluid after surgery. They are made of medical polymer materials and packaged in low-pressure PE bags.

[0003] The existing patented drainage bag, patent authorization number CN213554191U, has four transparent rubber columns set inside the drainage bag body through the cavity inside the drainage bag body and the transparent rubber columns in the cavity. The four transparent rubber columns are used to support the drainage bag body. After the liquid is poured into it, the four transparent rubber columns will expand the drainage bag body, making the drainage bag body diamond-shaped, avoiding the expansion of the drainage bag body, increasing the accuracy of the drainage volume statistics, and facilitating more practical use of the drainage bag.

[0004] However, existing conventional drainage bags, such as the one disclosed in patent authorization number CN213554191U, are prone to clogging of the catheter used to introduce body fluids into the drainage bag. This is especially true for drainage bags used in ICU surgeries. When the catheter of the drainage bag becomes clogged, the drainage bag needs to be replaced. This takes a considerable amount of time for medical staff during emergency treatment. If the replacement is not timely, medical accidents are likely to occur. Therefore, we propose a drainage bag for use during ICU surgery. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-4 A drainage bag for intraoperative use in an ICU comprises a drainage bag body 1, a liquid outlet 2 conductively connected to the bottom of the drainage bag body 1, and a liquid inlet conduit 3 conductively connected to the top of the drainage bag body 1. The drainage end of the liquid inlet conduit 3 is conductively connected to a connector 4, and a filter plate 5 is fixedly connected to the inner side of the connector 4;

[0026] A flushing pipe 6 is fixedly connected to one side of the filter plate 5 near the drainage end of the connector 4, and the flushing pipe 6 extends to the outside of the connector 4. A flushing head 7 is installed at one end of the flushing pipe 6 located inside the connector 4. An injection head 16 is connected to one end of the flushing pipe 6 located outside the connector 4. A liquid injection port 8 is provided at the end of the injection head 16 away from the connector 4. An annular boss 15 is fixedly connected to the inside of the injection head 16. A sealing ball 11 is provided on the side of the annular boss 15 near the liquid injection port 8, and the sealing ball 11 abuts against the liquid injection port 8. A spring 12 is installed between the sealing ball 11 and the annular boss 15.

[0027] The outer side of the injection head 16 is provided with an injection device 10, and the injection end of the injection device 10 is plugged and connected to the injection port 8;

[0028] The perfusion head 16 is away from the outer wall of the flushing tube 6 and is connected to the liquid outlet end 17;

[0029] It should be noted that during the use of the ICU intraoperative drainage bag, the tissue fluid to be drained from the human body is poured into the inner side of the drainage bag body 1 through the liquid inlet catheter 3. After the tissue fluid enters the inner side of the connecting head 4, the filter plate 5 is used to intercept the solid matter in the tissue fluid. At the same time, the perfusion device 10 with flushing fluid is inserted into the portion of the liquid injection port 8 provided at the perfusion head 16. By pressing the perfusion device 10, the sealing ball 11 is pushed open under the action of pressure, and the cleaning fluid enters the inner side of the flushing tube 6 through the perfusion head 16. Then, the tissue solid matter attached to the filter plate 5 is cleaned through the flushing head 7, and the cleaned solid tissue matter is discharged through the liquid outlet end 17 and collected by a container. After the perfusion device 10 is pulled out, the sealing ball 11 is reset by the elastic force of the spring 12. Therefore, the drainage bag body 1 can be effectively prevented from being blocked during the drainage of human tissue fluid. Medical staff do not need to replace the drainage bag body 1, which wins precious time for rescuing critically ill patients.

[0030] like Figure 3 As shown, a sealing rubber ring 9 is embedded on the inner side of the liquid injection port 8, and the sealing rubber ring 9 abuts against the outer wall of the end of the injection device 10;

[0031] It should be noted that the sealing effect of the joint between the injection end of the filling device 10 and the injection port 8 using the sealing rubber ring 9 can prevent gas leakage while preventing leakage, thereby improving the flushing effect of the filter plate 5 without leaking pressure.

[0032] like Figure 3 As shown, one end of the spring 12 is connected to the annular boss 15, and the other end of the spring 12 is connected to the sealing ball 11. The outer wall of the sealing ball 11 is symmetrically integrally formed with a guide rod 13, and the inner wall of the filling head 16 is provided with a guide groove 14 that is slidably connected to the end of the guide rod 13;

[0033] It should be noted that after the syringe 10 is pulled out, the guide rod 13 slides in cooperation with the guide groove 14, so that the elastic force of the spring 12 resets the sealing ball 11 to block the injection port 8 and prevent tissue fluid leakage.

[0034] like Figure 4 As shown, the port portion of the liquid outlet end 17 is detachably connected to a rubber plug 18, and the axial cross-section of the rubber plug 18 is T-shaped;

[0035] It should be noted that after cleaning is completed, a rubber plug 18 is installed at the liquid outlet end 17 to prevent leakage of tissue fluid.

[0036] Working principle: When in use, the tissue fluid to be drained from the human body is poured into the inner side of the drainage bag body 1 through the liquid inlet catheter 3. After the tissue fluid enters the inner side of the connecting head 4, the filter plate 5 is used to intercept the solid matter in the tissue fluid. At the same time, the syringe 10 with flushing fluid is inserted into the position of the injection port 8 set at the injection head 16. By pressing the syringe 10, the sealing ball 11 is pushed open under the action of pressure, and the cleaning fluid enters the inner side of the flushing tube 6 through the injection head 16. Then, the solid tissue matter attached to the filter plate 5 is cleaned through the flushing head 7, and the cleaned solid tissue matter is discharged through the liquid outlet end 17 and collected by the container. After the syringe 10 is pulled out, the elastic force of the spring 12 is used to reset the sealing ball 11, thereby effectively preventing the drainage bag body 1 from being blocked during the drainage of human tissue fluid, and there is no need for medical staff to replace the drainage bag body 1.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
