Description

Technical Field

[0001] The invention belongs to the technical field of ventricular drainage, and in particular relates to a ventricular drainage device. Background Art

[0002] With the development of neurosurgery, the scope of robotic surgery has been continuously expanded, requiring changes in medical tools. Intracerebral hematomas in different parts of the body require drainage tubes of different thicknesses and different heads to serve "robot-assisted intracerebral hematoma catheterization and drainage". Intracerebral hematoma catheterization and drainage often require drug injection after surgery, and there is a risk of intracranial infection. Drainage tubes that can continue to prevent intracranial infection and can inject drugs are needed. After the drainage tube is left in place after surgery for hypertensive cerebral hemorrhage, mannitol often needs to be dynamically adjusted. In the past, adjustments were made based on CT scans. If the drainage tube has the function of measuring intracranial pressure, it will be of great help to the treatment.

[0003] Traditional drainage tubes can only drain hematomas or cerebrospinal fluid, and have no drug injection or pressure measurement functions. Drugs need to be injected directly through the drainage tube, which can easily lead to reflux and intracranial infection. The diagnosis of the disease relies on follow-up CT scans, and treatment adjustments are not timely and increase radiation exposure. The head end specifications are single, making it difficult to adapt to the needs of robotic surgery for hematomas in complex areas. Summary of the Invention

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In the present invention, the ventricular drainage device integrates drainage, drug injection, and pressure measurement functions. The drainage function is achieved through the drainage tube main line, the drug injection line achieves the drug injection function, and the pressure measurement line and pressure measurement device achieve the pressure measurement function.

[0012] 2. In the present invention, a pressure measuring module is provided in the pressure measuring device, which provides real-time feedback of the intraventricular pressure situation through the pressure measuring pipeline. The user can dynamically adjust the treatment plan such as the dosage of mannitol according to the real-time pressure measurement data without the need for frequent CT examinations.

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.

[0018] Example

[0019] See also Figure 1-Figure 3As shown, the present invention provides a technical solution: a ventricular drainage device, comprising a drainage tube main line 1 and a pressure measuring device, a one-way valve 2 is provided at the lower end of the drainage tube main line 1, a drug injection line 3 is provided in the drainage tube main line 1, a one-way valve 2 is provided in the drug injection line 3, a silicone plug 5 is clamped at the end of the one-way valve 2 4, and a drainage hole 13 is provided at the lower end of the drainage tube main line 1. The ventricular drainage device integrates drainage, drug injection and pressure measuring functions in one. The drainage function is realized by the drainage tube main line 1, the drug injection line 3 realizes the drug injection function, and the pressure measuring line 6 and the pressure measuring device realize the pressure measuring function. This multifunctional integrated design reduces the operational risks brought about by the replacement of multiple instruments, simplifies the clinical operation process, and improves the treatment efficiency and safety. At the same time, the one-way valve 2 4 and the silicone plug 5 design in the drug injection line 3 effectively prevent the backflow of drug solution or cerebrospinal fluid, further reducing the risk of intracranial infection.

[0020] In this embodiment, specifically: a pressure measuring line 6 is provided in the drainage pipe main line 1, a one-way valve 3 7 is provided at the end of the pressure measuring line 6, and a pressure measuring connector 8 is clamped on one side of the one-way valve 3 7;

[0021] In this embodiment, specifically: a power supply 9, a central processing device 10, a pressure measuring module 11, and a wifi Bluetooth transmission module 12 are provided in the pressure measuring device. The pressure measuring module 11 is provided in the pressure measuring device, and the pressure situation in the ventricle is fed back in real time through the pressure measuring pipeline 6. The user can dynamically adjust the treatment plan such as the dosage of mannitol according to the real-time pressure measurement data, without the need for frequent CT examinations. This real-time dynamic monitoring function not only shortens the treatment cycle and reduces medical costs, but also improves the accuracy and effectiveness of the treatment. In addition, the wifi Bluetooth transmission module 12 is connected to the mobile device through wireless communication to realize remote transmission and monitoring of data, which is convenient for the user to grasp the patient's intracranial pressure at any time and adjust the treatment plan in time.

[0022] In this embodiment, specifically: the wifi bluetooth transmission module 12 is connected to the mobile device via wireless;

[0023] In this embodiment, specifically, the drainage holes 13 are provided in several groups.

[0024] Working principle or structural principle: When in use, a one-way valve 2 is provided at the lower end of the drainage tube main line 1 to ensure that the drainage fluid can only enter the drainage tube main line 1 from the ventricle through the drainage hole 13 and be discharged from the body to prevent the drainage fluid from flowing back. The drainage holes 13 are provided in several groups and distributed at the lower end of the drainage tube main line 1 to increase the drainage area, improve the drainage efficiency, and ensure that the fluid in the ventricle can be fully discharged. A liquid medicine injection line 3 is provided in the drainage tube main line 1 for injecting medicine into the ventricle. A one-way valve 4 is provided in the liquid medicine injection line 3, and its end is clamped with a silicone rubber. Plug 5, when it is necessary to inject the drug, the drug solution is injected into the drug solution injection pipeline 3 through the syringe, and the drug solution pushes the one-way valve 2 4 to open, so that the drug solution can smoothly enter the ventricle. After the injection is completed, the one-way valve 2 4 is automatically closed to prevent the drug solution from flowing back, ensuring that the drug can be accurately injected into the target area, increasing the local drug concentration and reducing the side effects of systemic medication. The design of the one-way valve 1 2 and the one-way valve 2 4 effectively prevents the backflow of drainage fluid and drug solution. The one-way valve 1 2 ensures that the drainage fluid can only go out but not in, and the one-way valve 2 4 ensures that the drug solution can only enter the ventricle in one direction, avoiding the side effects caused by backflow. The risk of intracranial infection caused by this is reduced, and the safety of drainage and drug injection is improved. A pressure measuring line 6 is provided in the main line 1 of the drainage tube, and a one-way valve 3 7 is provided at its end. A pressure measuring connector 8 is clamped on one side of the one-way valve 3 7. The pressure measuring device is provided with a power supply 9, a central processing device 10, a pressure measuring module 11 and a wifi Bluetooth transmission module 12. The pressure measuring connector 8 is connected to the pressure measuring device. When the inner core of the pressure measuring connector 8 pushes the one-way valve 3 7 open, the pressure measuring line 6 and the pressure measuring device are in a passage state. The pressure measuring module 11 monitors the intraventricular pressure in real time and transmits the data to the central processing device. The central processing device 10 wirelessly transmits the intracranial pressure data to a mobile device (such as a mobile phone or a nurse station device) through the WiFi Bluetooth transmission module 12. Medical staff can view the intracranial pressure data in real time through the mobile device and dynamically adjust the dosage of mannitol according to the data to avoid frequent CT scans, reduce the patient's radiation exposure, and improve the accuracy and efficiency of treatment. The pressure measuring device is also equipped with an alarm function. When the ventricular pressure is too high, the central processing device 10 will trigger an alarm to promptly remind medical staff to take corresponding measures to ensure the safety of the patient.
