[0002] External ventricular drainage is mainly used clinically for diseases such as hydrocephalus, intracranial infection, and cerebral hemorrhage. It can drain excess cerebrospinal fluid from the body, thereby alleviating hydrocephalus. It can also be used as an auxiliary treatment for symptoms such as fever and headache caused by diseases such as intracranial infection and cerebral hemorrhage. By puncturing the right frontal angle of the patient's ventricle, the purpose of draining the ventricle contents is achieved, thereby achieving the therapeutic effect.

[0003] The function of traditional drainage tubes is relatively simple. They can only drain accumulated fluid and cannot flush the pipes.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The present embodiment relates to a double-lumen extraventricular drainage tube, comprising an outer tube body 1, in which adjacent drainage tubes 2 and irrigation tubes 3 are simultaneously wrapped. The outer tube body 1 is implemented in a manner of limiting the drainage tubes 2 and irrigation tubes 3, and the drainage tubes 2 and irrigation tubes 3 respectively form independent lumens; the drainage tube 2 comprises an expansion port 4, a drainage main body 5, and a drainage tube blind end 7 integrally formed from one end to the other end, the drainage main body 5 is provided with a drainage port 6 near the drainage tube blind end 7, and an adjacent hole 8 is provided on one side of the drainage port 6; one end of the irrigation tube 3 is connected to a liquid inlet tube 11 and the other end forms an irrigation tube blind end 10, and the irrigation tube 3 is provided with an outlet hole 9 corresponding to the adjacent hole 8 near the irrigation tube blind end 10, that is, the lumen of the irrigation tube 3 is connected to the lumen of the drainage tube 2 through the corresponding connection between the outlet hole 9 and the adjacent hole 8.

[0024] Preferably, the portion of the drainage tube 2 wrapped in the outer tube body 1 is the drainage main body 5, and the drainage port 6 on the drainage main body 5 is located outside the outer tube body 1, that is, the flow of the medium at the drainage port 6 is not affected by the wrapping of the outer tube body 1. According to actual needs, the number of drainage ports 6 can be two. When the number of drainage ports 6 is two, the two drainage ports 6 are symmetrically arranged on the drainage main body 5. It can be understood that the drainage port 6 is used to connect and drain the contents of the ventricle.

[0025] The expansion port 4 gradually narrows at the point where it extends toward the drainage main body 5. Figure 1 As shown, the free end of the expansion port 4 has the largest diameter, the maximum diameter of the expansion port 4 is larger than the maximum diameter of the drainage main body 5, and the expansion port 4 is implemented in a manner of connecting to an external drainage device. The structural setting of the larger free end diameter of the expansion port 4 is conducive to the connection between the drainage tube 2 and the drainage device.

[0026] One end of the outer tube body 1 stops at the root of the drainage main body 5 near the connection between the expansion port 4 and the drainage main body 5. One end of the outer tube body 1 is also located at the bend where the flushing tube 3 is connected to the liquid inlet tube 11, so that the outer tube body 1 itself can be structurally limited.

[0027] The outlet hole 9 of the flushing tube 3 is located inside the package of the outer tube body 1, and the blind end 7 of the drainage tube of the flushing tube 3 is located outside the package of the outer tube body 1. According to the above structure, the adjacent interface 8 corresponding to the outlet hole 9 is also located inside the package of the outer tube body 1. The package of the outer tube body 1 prevents overflow that may occur when the outlet hole 9 and the adjacent interface 8 are connected to the flushing medium. The overflowing flushing medium will also be included in the outer tube body 1, and will not cause overflow infection or retrograde infection.

[0028] The free end of the liquid inlet pipe 11 is provided with a plug 12. The inner diameter of the tube body of the liquid inlet pipe 11 extending from the side of the plug 12 to the side of the flushing pipe 3 gradually narrows. When flushing is not required, the plug 12 blocks the liquid inlet pipe 11. By limiting the inner diameter of the liquid inlet pipe 11 to make it match the inner diameter of the flushing pipe 3, the flow of the flushing medium is smoother.

[0029] The maximum length of the drainage tube 2 is greater than the maximum length of the flushing tube 3 , and the maximum inner diameter of the drainage main body 5 is greater than the maximum inner diameter of the flushing tube 3 .

[0030] Preferably, the tube body of the drainage tube 2 forms a groove body that is adapted to the shape of the flushing tube 3, and the flushing tube 3 is adapted and adjacent to the drainage tube 2 in a complementary manner. It should be noted that the tube body of the drainage tube 2 is recessed inward to form a groove body that is adapted to the shape of the flushing tube 3. Therefore, when the drainage tube 2 and the flushing tube 3 are adapted and adjacent to each other, the overall tube body shape formed by the two is consistent with the shape of the drainage tube 2 in the non-recessed state. The stability of the connection between the two is strengthened by the adaptation and adjacency of the two, and then the connection is further wrapped by the outer tube body 1.

[0031] The openings at both ends of the outer tube body 1 are tightly connected to the tube surface of the drainage tube 2 and the flushing tube 3 respectively. Except for the openings at both ends, the outer tube body 1 is loosely matched with the drainage tube 2 and the flushing tube 3 respectively, and wraps the flushing medium that may overflow in turn.

[0032] It should be noted that in the practical application of this embodiment, in operations where flushing is not required, the ventricular contents drawn out from the drainage port 6 are sequentially led out by the drainage device through the drainage main body 5 and the expansion port 4. During this process, the ventricular contents will pass through the adjacent port 8. Since the flushing tube 3 and the liquid inlet tube 11 are in a single-end closed state under the action of the plug 12 at this time, there is air therein, so a large amount of ventricular contents will not flow into the flushing tube 3. A small amount of ventricular contents that flow into the flushing tube 3 will also be discharged together during the flushing process, so no pollution will be caused.

[0033] When a flushing process is required, the plug is opened and flushing is performed in sequence through the liquid inlet pipe 11 and the flushing pipe 3. The flushing medium enters the drainage pipe 2 through the outlet hole 9 and the adjacent port 8 to flush the inside of the pipe.

[0034] In this way, the double-lumen external ventricular drainage tube disclosed by the utility model has a simple structure and reasonable design. While ensuring the original function of the drainage tube and minimizing damage to the wound surface, an additional flushing tube is provided to flush all pipes, effectively preventing accumulation of dirt in the pipes and blockage, ensuring cleanliness and hygiene, and improving nursing efficiency.

[0035] The above implementation manner is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
