DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, an ommaya sac drainage device includes a puncture needle 1, a drainage tube 2, a drainage bag 3 and a shell 4. The puncture needle 1 is connected to the drainage bag 3 through the drainage tube 2. The puncture needle 1 is L-shaped. The L-shaped puncture needle 1 can make the horizontal section of the puncture needle 1 close to the patient's head skin after the tip of the puncture needle 1 is inserted into the fluid reservoir, which is convenient for fixing the puncture needle 1. Through the puncture needle 1, the drainage tube 2 and the drainage bag 3, continuous drainage of intracranial fluid can be achieved, which greatly reduces the workload of medical staff.

[0025] The drainage bag 3 is located in the shell 4, and a through hole 41 is provided on the side of the shell 4. The drainage tube 2 can pass through the through hole 41. The lower part of the shell 4 is provided with an avoidance groove 42, and the puncture needle 1 can be sunken in the avoidance groove 42. The lower surface of the shell 4 is arc-shaped, and a silicone patch 8 is connected to the lower surface of the shell 4. The shell 4 and the patient's head can be fixed by the silicone patch 8. When the puncture needle 1 is completed, the position of the puncture needle 1 is fixed by tape, and then the lower part of the shell 4 with the drainage bag 3 is abutted against the patient. The shell 4 is adhered to the patient's head through the silicone patch 8, and part of the puncture needle 1 is avoided through the avoidance groove 42. By placing the drainage bag 3 in the shell 4, the drainage assembly formed by the puncture needle 1, the drainage tube 2 and the drainage bag 3 can be integrated and fixed on the patient's head, effectively avoiding the puncture needle 1 from being dislocated when the patient is active, effectively ensuring the continuous drainage operation, and having good safety. By setting the silicone patch 8, not only can the discomfort of the patient wearing the shell 4 be reduced, but also the probability of pressure sores can be effectively reduced.

[0026] A limiting groove 43 is provided at the lower part of the shell 4, and the limiting groove 43 is located on the side of the avoidance groove 42. The drainage tube 2 can be embedded in the limiting groove 43 for limitation. The inner wall of the limiting groove 43 is connected with a first protrusion 44 and a second protrusion 45 that are staggered. The drainage tube 2 is limited by the first protrusion 44 and the second protrusion 45. Specifically, a plurality of first protrusions 44 are provided on one side of the limiting groove 43, and a second protrusion 45 is provided on the other side of the limiting groove 43. The second protrusion 45 is located between two adjacent first protrusions 44. Through the avoidance groove 42, the first protrusion 44 and the second protrusion 45, not only can the shell 4 be effectively prevented from compressing the drainage tube 2, but also the drainage tube 2 can be limited, thereby effectively reducing the probability of the puncture needle 1 being misplaced.

[0027] The shell body 4 is covered with an upper cover 5 on the upper part, and the upper cover 5 is fixedly connected to the shell body 4. The upper cover 5 includes a mounting port 51, and the mounting port 51 is covered with a detachable inner cover 6. Specifically, the lower part of the inner cover 6 is provided with a plurality of buckles 61, and the inner cover 6 abuts against the upper part of the upper cover 5. The buckles 61 pass through the lower part of the upper cover 5 and are buckled with the lower part of the upper cover 5. By providing the mounting port 51 and the inner cover 6, it is convenient to replace the drainage bag 3. The inner cover 6 is transparent, which is convenient for observing the condition of the drainage bag 3 in the shell body 4.

[0028] A handle 62 is provided on the upper portion of the inner cover 6 , and the handle 62 is provided to facilitate removal of the inner cover 6 .

[0029] The upper part of the upper cover 5 is connected to a detachable limiting plate 7, and the limiting plates 7 are located on both sides of the inner cover 6. Specifically, the upper cover 5 includes a plurality of limiting holes 52, and the lower part of the limiting plate 7 is provided with a convex rib 71 corresponding to the limiting hole 52, and the lower end of the convex rib 71 is provided with a boss 72, and the convex rib 71 can pass through the lower part of the limiting hole 52 and the upper part of the boss 72 can abut against the lower surface of the upper cover 5. The utility model can be used in conjunction with the existing product head net bag 9. After the puncture is completed and the shell 4 is pasted on the patient's head, in order to further improve the position fixing effect of the shell 4, a head net bag 9 can be covered at the patient's head, and the shell 4 is covered inside by the head net bag 9, and a hole can be cut at the head net bag 9 to expose the inner cover 6, and the head net bag 9 can be clamped by the limiting plate 7, so that the connection between the head net bag 9 and the shell 4 is more reliable.

[0030] The utility model also has a medical three-way connector 10 connected to the drainage tube 2. The medical three-way connector 10 is a prior art, and its specific structure is not described in detail in this description.
