[0031] As shown in Figure 1 The embodiment of the cerebrospinal fluid drainage device comprises a subcutaneous implant assembly 1, a puncture assembly 2 and a drainage assembly 3; the subcutaneous implant assembly 1 is implanted below the patient's scalp and communicates with the drainage site of the patient; the puncture assembly 2 is inserted into the subcutaneous implant assembly 1 and communicates with the subcutaneous implant assembly 1; the drainage assembly 3 is connected with the puncture assembly 2 and guides the cerebrospinal fluid into the drainage assembly 3 for drainage. By implanting the subcutaneous implant assembly 1 below the patient's scalp and communicating with the drainage site of the patient, when the patient needs to be drained, only the puncture assembly 2 needs to be inserted into the subcutaneous implant assembly 1, so that the effusion can be guided out of the body through the drainage assembly 3, relieving the patient's increased intracranial pressure and ensuring normal intracranial pressure. Without opening the wound for intubation, the drainage operation is simple, reducing the risk of operation and infection risk.
[0032] As shown in Figure 2As shown in some embodiments of the utility model, the subcutaneous implant assembly 1 includes an implant tube 10, a liquid storage bag 11 and a bottom plate 12, the bottom plate 12 is arranged in close contact with the skull of the patient, the liquid storage bag 11 is arranged on the bottom plate 12, one end of the implant tube 10 is in communication with the liquid storage bag 11, and the other end is in communication with the drainage site of the patient. Through one-time incision surgery, the subcutaneous implant assembly 1 is implanted under the scalp of the patient, the implant tube 10 penetrates the skull incision and reaches the site to be drained in the patient, the bottom plate 12 is arranged in close contact with the skull of the patient, so that the subsequent drainage needle operation is stable, the liquid storage bag 11 is used for storing the effusion drained through the implant tube 10, and the effusion is discharged outside the body through the puncture assembly 2 and the drainage assembly 3, the intracranial pressure of the patient is relieved, the normal intracranial pressure is ensured, after the subcutaneous implant assembly 1 is implanted, the wound does not need to be opened again for intubation in the subsequent drainage process, the drainage operation is simple, and the operation risk and infection risk are reduced.
[0033] As shown in some embodiments of the utility model, Figure 3 As shown in some embodiments of the utility model, the implant tube 10 is arranged below the liquid storage bag 11 through the bottom plate 12. The effusion is directly introduced into the liquid storage bag 11 through the implant tube 10, and generally, the implant position of the subcutaneous implant assembly 1 is located above the skull incision.
[0034] As shown in some embodiments of the utility model, Figure 4 As shown in some embodiments of the utility model, the implant tube 10 is arranged below the liquid storage bag 11 through the bottom plate 12. The effusion is directly introduced into the liquid storage bag 11 through the implant tube 10, and generally, the implant position of the subcutaneous implant assembly 1 is located above the skull incision.
[0035] In some embodiments of the utility model, the bottom and / or side wall of the implant tube 10 is provided with a drainage hole. The bottom of the implant tube 10 is provided with a drainage hole, which can directly reach the drainage site and directly guide the effusion into the implant tube 10 and discharge upward; the side wall of the implant tube 10 is provided with a drainage hole, which can collect the effusion at multiple positions around or vertically to the drainage site and make the effusion converge to the implant tube 10 and discharge upward. The above two kinds of hole opening modes can be selected or exist simultaneously.
[0036] As shown in some embodiments of the utility model, Figures 2 to 4As shown, in some embodiments of this utility model, the reservoir 11 has a hollow structure, and a puncture platform 110 for inserting the puncture assembly 2 is provided at the top of the reservoir 11. The hollow structure of the reservoir 11 facilitates temporary storage of fluid and also makes it easier to observe intracranial pressure; when the pressure is high, the reservoir 11 will bulge upwards. The puncture platform 110 has a large operating surface, which facilitates medical personnel in finding the insertion position of the puncture assembly 2 during drainage operations, reducing the error rate.
[0037] In some embodiments of this invention, the reservoir 11 is made of silicone material. Silicone material has good self-adaptability, allowing the puncture component 2 to pass through the reservoir 11 for drainage. Furthermore, after the puncture component 2 is removed, the needle hole in the reservoir 11 will self-close, providing good sealing and ensuring repeatable punctures.
[0038] In some embodiments of this invention, the base plate 12 is made of polypropylene. The base plate 12 is sturdy and flat, allowing for stable implantation onto the subcutaneous bone. Simultaneously, the base plate 12 effectively prevents the puncture component 2 from penetrating too deeply during puncture.
[0039] like Figures 2 to 5 As shown, in some embodiments of this utility model, the puncture assembly 2 includes a fixing cover 20 and a puncture needle 21. The fixing cover 20 is fitted onto the puncture needle 21, and the fixing cover 20 matches the reservoir 11. In use, medical personnel determine the approximate position of the reservoir 11 by observing the upward bulge of the scalp, and then insert the puncture needle 21 into the center of the reservoir 11. During the insertion process, the fixing cover 20 moves downward simultaneously and covers the bulging scalp. The fixing cover 20 and the puncture platform 110 together clamp the scalp, making the drainage process stable and preventing needle tilting, thus avoiding fluid leakage.
[0040] like Figure 1 As shown, in some embodiments of this utility model, the drainage assembly 3 includes a drainage tube 30, a drainage bag 31, and a three-way valve 32. One end of the drainage tube 30 is connected to the puncture needle 21, and the other end is connected to the drainage bag 31. The three-way valve 32 is disposed on the drainage tube 30. The drainage tube 30 is a flexible tube, and its length and shape are not limited to the drawings of this application. The drainage bag 31 may also be provided with graduations to facilitate collection and observation by medical personnel. The three-way valve 32 can realize the opening and closing of the fluid in the drainage tube 30. For example, when the fluid in one drainage bag 31 is full, a new drainage bag 31 needs to be replaced. Then, another drainage tube 30 is connected to the other connector of the three-way valve 32. By changing the opening and closing state of the three-way valve 32, the subsequent fluid enters the replaced drainage bag 31, realizing the replacement operation.
