[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 and Figure 2 As shown, the present invention provides an external drainage device for an Ommaya reservoir, comprising:

[0028] Flexible fixing disk 1, which bends when subjected to force;

[0029] The drainage needle 2 includes an insertion part 3 and a fixing part 4 that are connected to each other. The fixing part 4 is placed flat inside the flexible fixing plate 1, and the insertion part 3 is vertically connected to the bottom of the flexible fixing plate 1.

[0030] A connecting hose 5 is disposed inside the flexible fixing plate 1, and the connecting hose 5 bends when subjected to force; the connecting hose 5 is connected to the fixing part 4 of the drainage needle 2;

[0031] A drainage hose 6 is connected to a connecting hose 5, and a connecting connector 7 is fixed to the end of the drainage hose 6 away from the connecting hose 5;

[0032] The sealing gasket 8 is fixed to the bottom of the flexible fixing plate 1 and is disposed on the outer surface of the insertion part 3. The sealing gasket 8 is elastic and deforms when compressed.

[0033] Adhesive material 9 is placed at the bottom of flexible fixing plate 1 and sealing gasket 8 to fix flexible fixing plate 1 and sealing gasket 8;

[0034] The liquid inside the Ommaya reservoir is drained out through the drainage needle 2, connecting tubing 5, and drainage tubing 6.

[0035] The length of the insertion part 3 is 1.2-1.8mm.

[0036] Currently, external drainage devices for Ommaya reservoirs lack a fixed structure. Clinicians typically rely on experience to bend the intravenous infusion needle into a fishhook shape and insert it percutaneously into the Ommaya reservoir for drainage. This is usually achieved through suturing, which can lead to problems such as insecure fixation, easy dislodgement, scalp damage, increased risk of infection, and pressure fixation, which can also hinder drainage. Therefore, it is essential to develop an external drainage device for Ommaya reservoirs.

[0037] This embodiment fixes the drainage needle 2 inside the flexible fixation plate 1, thus standardizing the curvature of the scalp needles. It eliminates the need for additional needle bending and replaces suture fixation with adhesive fixation. At the same time, the flexible fixation plate 1 and the sealing gasket 8 can change their shape to conform to the patient's scalp during fixation, ensuring a firm fixation and reducing fixation steps. This reduces patient pain, enhances drainage effect, reduces infection rate, fully utilizes the drainage function of the Ommaya sac, and maximizes patient recovery.

[0038] In actual use, (1) patients who require long-term drainage are selected from those who have had an Ommaya sac implanted.

[0039] (2) For the above patients, determine the location of the Ommaya capsule implantation and mark it with a marker.

[0040] (3) Before puncturing the Ommaya sac, the hair within 15cm×10cm around the sac must be shaved. Then, insert the insertion part 3 of the drainage needle 2 into the Ommaya sac. At the same time, bend the flexible fixation plate 1 and the sealing pad 8. Meanwhile, the connecting tube 5 is also bent so that the flexible fixation plate 1 and the sealing pad 8 fit the patient's head. And fix the flexible fixation plate 1 and the sealing pad 8 to the patient's head with the adhesive dressing 9.

[0041] (4) The liquid inside the Ommaya reservoir is drained out through the drainage needle 2, the connecting tubing 5 and the drainage tubing 6.

[0042] In a preferred embodiment of this method, the angle between the insertion part 3 and the fixing part 4 is 90 degrees for better drainage. The insertion part 3 and the fixing part 4 are arranged perpendicularly, which facilitates fixing the drainage needle 2 and makes the drainage smoother.

[0043] To ensure a better fit and fixation of the device to the patient's head, the length of the fixing part 4 is less than one-third the length of the insertion part 3. If the fixing part 4 is too long, it will affect the bending of the flexible fixing plate 1 and the sealing gasket 8, thus affecting the fixation of the device.

[0044] Before this device is used, the drainage needle 2 is easily contaminated. In order to protect the drainage needle 2, such as... Figure 2As shown, the adhesive material 9 has a release paper 10 at its bottom, and the outer surface of the insertion part 3 has a protective sleeve 11, which is fixedly connected to the release paper 10. The protective sleeve 11 protects the drainage needle 2. In use, the release paper 10 is torn off, and the release paper 10 and the protective sleeve 11 are removed for use.

[0045] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
