Description

Technical Field

[0001] The present invention belongs to the technical field of cerebrospinal fluid purification equipment, and in particular relates to a disposable pipeline installation system for continuous purification treatment of artificial cerebrospinal fluid. Background Art

[0002] With advancements in neurosurgical techniques, the mortality rate from primary causes has decreased, while the mortality and severe neurological deficits caused by secondary brain damage remain high. Drug treatments for chronic degenerative neurological diseases and autoimmune neurological disorders are limited in effectiveness; effective drug delivery methods to the central nervous system are still under investigation. The management of intracranial hypertension, cerebral edema, and brain damage, the rapid purification of the cerebrospinal fluid environment, and the smooth implementation of local hypothermia therapy are currently bottlenecks hindering the development of neurology and urgently need to be addressed. Acute intracranial lesions such as brain trauma, cerebrovascular accidents, intracranial infections, and acute Guillain-Barré syndrome all cause alterations in the chemical composition and circulation dynamics of the cerebrospinal fluid, resulting in a series of pathophysiological reactions that lead to early and delayed brain damage, even life-threatening conditions. The pathophysiological mechanisms of brain injury are extremely complex.

[0003] At present, it is still not clear in the clinic that there is no truly 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 body through a cerebrospinal fluid purification system and a ventricular drainage tube, thereby achieving the purification of 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:

[0004] 1. In clinical use, lumbar spine treatment is mostly used for treatment, which has poor effect on cerebrospinal fluid purification in the ventricles and low efficiency of cerebrospinal fluid purification;

[0005] 2. The cerebrospinal fluid drainage and injection ports of traditional cerebrospinal fluid purification systems are close to each other, resulting in poor purification and replacement effects;

[0006] 3. Traditional cerebrospinal fluid purification systems are prone to blockage near the drainage port, resulting in drainage failure, requiring extubation and resetting, which will interrupt treatment;

[0007] 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. Summary of the Invention

[0013] The implantable outer tube is a tubular structure, and a plurality of artificial cerebrospinal fluid injection ports are provided at the distal end of the implantable outer tube. The artificial cerebrospinal fluid injection ports are used in conjunction with the artificial cerebrospinal fluid replenishing mechanism provided on the outside of the implantable outer tube;

[0014] The placement tube positioning mechanism is provided on the implanted outer tube and is used in conjunction with the drainage tube;

[0015] The drainage tube is arranged inside the implanted outer tube, and an injection cavity is formed between the implanted outer tube and the drainage tube. A plurality of drainage holes are arranged at one end of the drainage tube, and the drainage holes are used in conjunction with the implanted tube positioning mechanism. A drainage mechanism is also arranged at the other end of the drainage tube.

[0016] As a preferred embodiment of the present invention, the insertion tube positioning mechanism includes:

[0017] A syringe is provided at one end of the water bag control line extending out of the outer implant tube and is connected to the outer implant tube;

[0018] The water bag control pipeline is arranged in the liquid injection cavity, and the other end of the water bag control pipeline is connected to the water bag;

[0019] The water bag is arranged on one end of the implanted outer tube close to the artificial cerebrospinal fluid injection port and is communicated with the water bag control pipeline.

[0020] As a preferred embodiment of the present invention, the water bag 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 are provided inside the water bag, which are used in conjunction with the drainage port.

[0021] As a preferred solution of the present invention, the drainage end of the drainage tube is a conical structure, and a circular arc end face is provided at the front end of the conical structure, and the drainage hole is provided on the inclined surface of the conical structure. The conical structure is also used in conjunction with a water bag.

[0022] As a preferred solution of the present invention, a corrugated spiral guide groove is provided in the inner wall of the front end of the drainage tube. The corrugated spiral guide groove is provided at one end close to the drainage hole and has a corrugated spiral structure.

[0023] As a preferred embodiment of the present invention, the artificial cerebrospinal fluid injection port is opened on the implant outer tube at an angle toward the rear.

[0024] As a preferred embodiment of the present invention, the artificial cerebrospinal fluid replenishment mechanism is connected to the injection cavity through an injection port provided on the implanted outer tube, and includes an artificial cerebrospinal fluid replenishment hose, one end of which is connected to the injection cavity through the injection port, and the other end is connected to the artificial cerebrospinal fluid storage bag.

[0025] As a preferred solution of the present invention, a first micro pump and an intracranial pressure monitoring device are further provided on the pipeline of the artificial cerebrospinal fluid replenishment hose.

[0026] As a preferred embodiment of the present invention, the drainage mechanism includes an infected cerebrospinal fluid output hose, one end of which is connected to the drainage tube, and the other end is connected to the waste fluid storage bag, and a second micro pump is provided on the pipeline of the infected cerebrospinal fluid output hose.

[0027] (3) Beneficial effects

[0028] 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:

[0029] 1. By providing an implantable external tube and a drainage tube that work in conjunction with each other, the infected cerebrospinal fluid can be extracted and replaced during use. At the same time, the distance between the artificial cerebrospinal fluid injection port and the drainage hole can be effectively controlled, ensuring the replacement efficiency of the infected cerebrospinal fluid.

[0030] 2. Through the setting of the insertion tube positioning mechanism, the water bag is tightly attached to the end face of the drainage tube when in the contracted state, which makes it easier for the device to reduce its cross-section and be placed into the ventricle through the catheter. The water bag can also prevent foreign objects from clogging the drainage port during the insertion process. The rubber water bag can also play a certain buffering role during the insertion process, making it more soothing and more humane when in contact with the ventricular tissue. At the same time, the water bag is opened in an umbrella shape by injecting medical sterile water through the distal syringe, fully exposing the drainage port, while preventing the drainage port from being close to the ventricular tissue and affecting the drainage efficiency. After the water bag is expanded, the artificial cerebrospinal fluid injection port and the drainage port are separated in a certain area, further preventing the injected artificial cerebrospinal fluid from being directly drained out, resulting in low replacement efficiency. When the drainage port is detected to be blocked, the blockage dredging block can be cleared in the drainage port area by controlling the expansion and contraction of the water bag, avoiding treatment interruption caused by pipeline resetting.

[0031] 3. A corrugated spiral guide groove is set on the inner wall of the front section of the drainage inner tube to make the cerebrospinal fluid flowing in produce a rotation effect, draining it outward while rotating. The rotation state will greatly reduce the probability of blockage at the end of the drainage tube;

[0032] 4. By setting the artificial cerebrospinal fluid injection port at the front end of the implanted external tube to be tilted backward, on the one hand, the injection speed of the artificial cerebrospinal fluid can be further buffered to reduce direct impact on the ventricle; on the other hand, the injection direction of the artificial cerebrospinal fluid can be changed, so that the injected cerebrospinal fluid is further away from the drainage port. Combined with the isolation of the water bag and the flow effect of the ventricle itself, the replacement efficiency is improved; the purpose of facilitating cerebrospinal fluid purification and replacement, preventing blockage near the drainage port, and achieving a good cerebrospinal fluid purification effect is achieved.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0041] See also Figure 1-6 , the present invention provides a technical solution:

[0042] A disposable pipeline installation system for continuous purification treatment of artificial cerebrospinal fluid, comprising an implantable outer tube 1, an implanted tube positioning mechanism 2 and a drainage tube 10; wherein

[0043] The implantable outer tube 1 is a tubular structure, and a plurality of artificial cerebrospinal fluid injection ports 12 are provided at the distal end of the implantable outer tube 1. The artificial cerebrospinal fluid injection ports 12 are used in conjunction with an artificial cerebrospinal fluid supplementation mechanism provided on the outside of the implantable outer tube 1.

[0044] The insertion tube positioning mechanism 2 is provided on the implant outer tube 1 and is used in conjunction with the drainage tube 10;

[0045] The drainage tube 10 is arranged in the implantable outer tube 1, and an injection cavity 13 is formed between the implantable outer tube 1 and the drainage tube 10. A plurality of drainage holes 102 are provided at one end of the drainage tube 10. The drainage holes 102 cooperate with the implantable tube positioning mechanism 2. The other end of the drainage tube 10 is also provided with a drainage mechanism.

[0046] 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 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 inlet 12.

[0047] 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 line 22 and a water bag 23;

[0048] The syringe 21 is arranged at one end of the water bag control line 22 extending out of the outer side of the implantable outer tube 1 and is connected to the implantable outer tube 1;

[0049] The water bag control line 22 is placed in the liquid injection cavity 13, and the other end of the water bag control line 22 is connected to the water bag 23;

[0050] 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 line 22;

[0051] 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 drainage area that is too small 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 clearing block 24 can be cleared 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.

[0052] 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 provided on the inner side of the water bag 23. The blocking and dredging blocks 24 are used in conjunction with the drainage port 102.

[0053] 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, causing the water bag 23 to open 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 clearing block 24 can be cleared in the drainage port 102 area by controlling the expansion and contraction of the water bag 23, thereby avoiding the occurrence of treatment interruption caused by pipeline blockage.

[0054] 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. The drainage hole 102 is provided on the inclined surface of the conical structure. The conical structure is also used in conjunction with the water bag 23.

[0055] 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 for blockage. When multiple drainage holes 102 are blocked, the drainage holes 102 can be unblocked using the blockage unblocking block 24 by changing the state of the water bag 23.

[0056] 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 inner wall of the front end 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.

[0057] When in use, the cerebrospinal fluid is guided by the corrugated spiral guide groove in the drainage tube 10, so that the cerebrospinal fluid flowing in produces a rotation effect, and is drained out while rotating. The rotation state greatly reduces the probability of blockage at the end of the drainage tube.

[0058] 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 so that the injected cerebrospinal fluid is further away from the drainage hole 102. Combined with the isolation of the water bag 23 and the flow effect of the ventricle itself, the replacement efficiency is better.

[0059] As a preferred embodiment, Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the artificial cerebrospinal fluid replenishment mechanism is connected to the injection cavity 13 through an injection port 11 provided 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 to the injection cavity 13 through the injection port 11, and the other end is connected to the artificial cerebrospinal fluid storage bag 3. A first micro pump 6 and an intracranial pressure monitoring device 8 are also provided on the pipeline of the artificial cerebrospinal fluid replenishment hose 7;

[0060] In this embodiment, when in use, the first micropump 6 controls the pressure of the artificial cerebrospinal fluid in the artificial cerebrospinal fluid replenishment hose 7 during the artificial cerebrospinal fluid replenishment process, and performs stable pressure replenishment of artificial cerebrospinal fluid into the ventricles. 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 micropump 6 to control the opening of the first micropump 6.

[0061] 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 provided on the pipeline of the infected cerebrospinal fluid output hose 4;

[0062] 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 micropump 9 to effectively extract the infected cerebrospinal fluid.

[0063] The use process and principle of the disposable pipeline installation system for continuous purification treatment of artificial cerebrospinal fluid of the present invention include:

[0064] During use, the front end of the implantable outer tube 1 and the drainage tube 10 are implanted into the brain, and after reaching 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 implantable 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 intraventricular pressure monitoring device 8 can detect the pressure in the ventricle and control the operation of the first micro pump 6 to achieve stable pressure replenishment of artificial cerebrospinal fluid into the ventricle.

[0065] At the same time, when it is found that the drainage port 102 is blocked, the drainage hole 102 is cleared by using the blockage clearing block 24 by changing the state of the water bag 23 .

[0066] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations.
