[0002] With the improvement of neurosurgery techniques, the probability of death caused by primary causes has decreased, while death and severe neurological dysfunction caused by secondary brain damage remain high. The drug treatment effect of chronic degenerative neurological diseases and neurological autoimmune diseases is limited; effective drug delivery methods for the central nervous system are still under study; the control and management of intracranial hypertension, cerebral edema, brain damage, rapid purification of the cerebrospinal fluid environment, and the smooth implementation of local hypothermia treatment have become bottlenecks restricting the development of neurology and urgently need to be solved. Acute intracranial lesions such as brain trauma, cerebrovascular accident, intracranial infection, and acute Guillain-Barré syndrome all cause changes in the chemical composition of cerebrospinal fluid and its circulation dynamics, resulting in a series of pathophysiological reactions, leading to the occurrence of early brain damage and delayed brain damage, and even life-threatening. The pathophysiological mechanism of brain damage is extremely complex.

[0003] At present, there is still no clinically effective measure to improve the prognosis. The solute transport of cerebrospinal fluid is an important way to remove toxic molecules and metabolites from the brain and to deliver nutrients to brain cells. It plays an important role in the pathophysiological process of the central nervous system. There is mutual communication between the cerebrospinal fluid and the interstitial fluid of the brain tissue, which directly affects the living environment of the central nervous cells. Correction and management of the homeostasis of the cerebrospinal fluid environment. In the treatment of cerebrospinal fluid, cerebrospinal fluid purification is a method of purifying the cerebrospinal fluid in the patient's ventricles through specific medical equipment or technology. Specifically, cerebrospinal fluid purification is to drain the cerebrospinal fluid in the patient's ventricles to the outside of the body through a cerebrospinal fluid purification system and a ventricular drainage tube, thereby purifying the cerebrospinal fluid. When using the cerebrospinal fluid purification method to treat patients with cerebrospinal fluid, the above-mentioned cerebrospinal fluid purification method and system still have problems such as: 1. In clinical use, lumbar spine treatment is mostly used, which has poor effect on cerebrospinal fluid purification in the ventricles and low efficiency of cerebrospinal fluid purification; 2. The cerebrospinal fluid drainage and injection ports of the traditional cerebrospinal fluid purification system are close to each other, resulting in poor purification and replacement effects; 3. The drainage port of the traditional cerebrospinal fluid purification system is prone to blockage, resulting in drainage failure, requiring tube removal and resetting, which will interrupt treatment; Therefore, the present invention proposes a disposable pipeline installation system for continuous purification treatment of artificial cerebrospinal fluid to solve the problems raised by the above-mentioned prior art.

[0014] (III) Beneficial effects Compared with the prior art, the present invention provides a disposable pipeline installation system for continuous purification treatment of artificial cerebrospinal fluid, which has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-6 , the present invention provides a technical solution: A disposable pipeline installation system for continuous purification treatment of artificial cerebrospinal fluid, comprising an implanted outer tube 1, an implanted tube positioning mechanism 2 and a drainage tube 10; wherein The implant outer tube 1 is a tubular structure, and a plurality of artificial cerebrospinal fluid injection ports 12 are arranged at the distal end of the implant outer tube 1. The artificial cerebrospinal fluid injection ports 12 are used in conjunction with an artificial cerebrospinal fluid supplement mechanism arranged outside the implant outer tube 1. The insertion tube positioning mechanism 2 is arranged on the implant outer tube 1 and is used in conjunction with the drainage tube 10; The drainage tube 10 is arranged inside the implanted outer tube 1, and a liquid injection cavity 13 is formed between the implanted outer tube 1 and the drainage tube 10, and a plurality of drainage holes 102 are arranged at one end of the drainage tube 10, and the drainage holes 102 are used in conjunction with the implanted tube positioning mechanism 2, and a drainage mechanism is also arranged at the other end of the drainage tube 10; In this embodiment, when in use, the implantation position of the implanted outer tube 1 is positioned by the insertion tube positioning mechanism 2. At the same time, the insertion tube positioning mechanism 2 can also avoid clogging of the drainage hole 102 when the artificial cerebrospinal fluid replenishing mechanism is used to replenish the fluid. The drainage mechanism is used to extract the infected cerebrospinal fluid through the drainage hole 102, and the artificial cerebrospinal fluid replenishing mechanism is used to stably inject artificial cerebrospinal fluid into the patient through the artificial cerebrospinal fluid injection port 12.

[0019] As a preferred embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the insertion tube positioning mechanism 2 includes a syringe 21, a water bag control pipeline 22 and a water bag 23; wherein The syringe 21 is arranged at one end of the water bag control pipeline 22 extending out of the outer side of the implanted outer tube 1 and is connected to the implanted outer tube 1; The water bag control pipeline 22 is placed in the injection cavity 13, and the other end of the water bag control pipeline 22 is connected to the water bag 23; The water bag 23 is arranged on one end of the implant outer tube 1 close to the artificial cerebrospinal fluid injection port 12 and is connected to the water bag control pipeline 22; In this embodiment, medical sterile water is injected into the water bag 23 through the syringe 21 to expand the water bag 23. According to the design shape of the water bag 23, the water bag 23 is opened in an umbrella shape to fully expose the drainage port 102. At the same time, the water bag 23 expands to prevent the drainage port 102 from being close to the ventricular tissue, resulting in a small drainage area and affecting the drainage efficiency. More cleverly, after the water bag 23 is expanded, the artificial cerebrospinal fluid injection port 12 and the drainage port 102 are separated in a certain area, and then with the help of the slow flow of the cerebrospinal fluid in the ventricle itself, the injected artificial cerebrospinal fluid is further prevented from being directly drained out, resulting in low replacement efficiency. When the drainage port 102 is detected to be blocked, the blockage unblocking block 24 can be unblocked in the drainage port 102 area by controlling the expansion and contraction of the water bag 23 to avoid treatment interruption caused by pipeline blockage.

[0020] As a preferred embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the water bag 23 is a trumpet-shaped structure with a large diameter at the free end and a small diameter at the fixed end, and a plurality of blocking and dredging blocks 24 are arranged on the inner side of the water bag 23, and the blocking and dredging blocks 24 are used in conjunction with the drainage port 102; In this embodiment, when medical sterile water is injected into the water bag 23 through the syringe 21, the sterile water can expand the water bag 23, so that the water bag 23 opens in an umbrella shape, fully exposing the drainage port 102, and at the same time the water bag 23 expands to prevent the drainage port 102 from being close to the ventricular tissue, causing the drainage area to be too small, affecting the drainage efficiency; at the same time, after the water bag 23 is expanded, the artificial cerebrospinal fluid injection port 12 and the drainage port 102 are separated in a certain area, and then with the help of the slow flow of the cerebrospinal fluid in the ventricle itself, the injected artificial cerebrospinal fluid is further prevented from being directly drained out, causing the problem of low replacement efficiency; and when the drainage port 102 is detected to be blocked, the blockage unblocking block 24 can be unblocked in the drainage port 102 area by controlling the expansion and contraction of the water bag 23 to avoid the interruption of treatment caused by pipeline blockage.

[0021] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the drainage end of the drainage tube 10 is a conical structure, and a circular arc end surface is provided at the front end of the conical structure, and the drainage hole 102 is provided on the inclined surface of the conical structure, and the conical structure is also used in conjunction with the water bag 23; In this embodiment, when in use, the conical structure is designed to facilitate the implantation of the front end of the drainage tube 10 into the brain; by providing an arc-shaped end face at the front end of the drainage tube 10, damage to the ventricle can be avoided during the implantation of the front end of the drainage tube 10 into the brain; the drainage holes 102 are provided on the inclined surface of the conical structure, which can increase the fault tolerance rate of blockage. When multiple drainage holes 102 are blocked, the drainage holes 102 are unblocked by changing the state of the water bag 23 and using the blockage unblocking block 24.

[0022] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a corrugated spiral guide groove 101 is provided in the front inner wall of the drainage tube 10. The corrugated spiral guide groove 101 is provided at one end close to the drainage hole 102 and is a corrugated spiral structure; When in use, the cerebrospinal fluid is guided by the corrugated spiral guide groove in the drainage tube 10, so that the cerebrospinal fluid drained in produces a rotation effect, and the fluid is drained out while rotating. The rotation state greatly reduces the probability of blockage at the end of the drainage tube.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the artificial cerebrospinal fluid injection port 12 is tilted backward and opened on the implant outer tube 1. On the one hand, the injection speed of the artificial cerebrospinal fluid can be further buffered to reduce the direct impact on the ventricle; on the other hand, the injection direction of the artificial cerebrospinal fluid can be changed to make the injected cerebrospinal fluid farther away from the drainage hole 102, and combined with the isolation of the water bag 23 and the flow effect of the ventricle itself, the replacement efficiency is better.

[0024] As a preferred embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the artificial cerebrospinal fluid replenishment mechanism is connected with the injection cavity 13 through the injection port 11 arranged on the implant outer tube 1, and includes an artificial cerebrospinal fluid storage bag 3 and an artificial cerebrospinal fluid replenishment hose 7. One end of the artificial cerebrospinal fluid replenishment hose 7 is connected with the injection cavity 13 through the injection port 11, and the other end is connected with the artificial cerebrospinal fluid storage bag 3, and a first micro pump 6 and a cranial pressure monitoring device 8 are also arranged on the pipeline of the artificial cerebrospinal fluid replenishment hose 7; In this embodiment, when in use, the first micro-pump 6 is used to control the pressure of the artificial cerebrospinal fluid in the artificial cerebrospinal fluid replenishment hose 7 during the artificial cerebrospinal fluid replenishment process, and the artificial cerebrospinal fluid is replenished into the ventricles with stable pressure. At the same time, the replenishment pressure of the artificial cerebrospinal fluid in the ventricles is controlled according to different replenishment needs; the intravenous pressure monitoring device 8 can detect the pressure in the ventricles to form information input for negative feedback regulation of the first micro-pump 6 to control the opening of the first micro-pump 6.

[0025] As a preferred embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the drainage mechanism includes an infected cerebrospinal fluid output hose 4 and a waste liquid storage bag 5, one end of the infected cerebrospinal fluid output hose 4 is connected to the drainage tube 10, and the other end is connected to the waste liquid storage bag 5, and a second micro pump 9 is arranged on the pipeline of the infected cerebrospinal fluid output hose 4; In this embodiment, the infected cerebrospinal fluid is extracted into the waste fluid storage bag 5 through the insertion of the tube positioning mechanism 2 and the infected cerebrospinal fluid output hose 4, and the pressure and opening of the infected cerebrospinal fluid output hose 4 are controlled by the second micro pump 9 to effectively extract the infected cerebrospinal fluid.

[0026] The use process and principle of the disposable pipeline installation system for continuous purification treatment of artificial cerebrospinal fluid of the present invention include: When in use, the front end of the implanted outer tube 1 and the drainage tube 10 are implanted into the brain, and when they reach the designated position, medical sterile water is injected into the water bag 23 through the syringe 21 to expand the water bag 23. According to the design shape of the water bag 23, the water bag 23 is opened in an umbrella shape to fully expose the drainage port 102, and the implanted outer tube 1 and the drainage tube 10 are positioned. Then, according to the use requirements, the second micro pump 9 is controlled to operate to extract the infected cerebrospinal fluid into the waste liquid storage bag 5. At the same time, the intravenous pressure monitoring device 8 can detect the pressure in the cerebral ventricle, and the first micro pump 6 is controlled to operate to achieve stable pressure supplementation of artificial cerebrospinal fluid into the cerebral ventricle. Meanwhile, when the drainage port 102 is found to be blocked, the drainage hole 102 is cleared by using the blockage clearing block 24 by changing the state of the water bag 23 .
