Description

Technical Field

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

[0002] Ventricular drainage surgery is one of the common methods for treating intracranial hypertension. It is usually used for hydrocephalus, intracranial hemorrhage, brain tumors or severe craniocerebral trauma. By drilling a hole in the skull and inserting a drainage tube into the lateral ventricle, the excess cerebrospinal fluid is drained, helping to reduce intracranial pressure and avoid excessive compression of brain tissue. However, the current ventricular drainage equipment still has the following problems that need to be improved in practical applications:

[0003] Imprecise drainage flow and speed control: Existing drainage devices mainly rely on gravity for drainage, and control the flow by manually adjusting the position of the pipe or a simple mechanical device. This design makes it difficult to accurately control the drainage speed and flow, and is prone to secondary damage. For example, too fast drainage may cause a sharp drop in ventricular pressure, causing ventricular collapse or brain tissue displacement; while too slow a drainage speed may not effectively reduce intracranial pressure, prolonging the course of the disease and aggravating the patient's symptoms.

[0004] Lack of automation and intelligent adjustment functions: Most current drainage devices require medical staff to frequently manually adjust the drainage speed according to the patient's condition, which not only increases the complexity of operation, but also easily leads to human errors, resulting in loss of control of the drainage process. In addition, medical staff also need to continuously monitor the patient's intracranial pressure, and cannot achieve real-time dynamic drainage adjustment, and cannot perform automated operations according to changes in the patient's condition.

[0005] High risk of postoperative complications: During the drainage process, the drainage fluid is exposed to the outside world for a long time, and the existing devices lack effective antibacterial and anti-reflux designs, which can easily cause infection and increase the incidence of postoperative complications. In addition, if the fluid in the drainage tube flows back into the ventricle, it may cause cerebrospinal fluid reflux and secondary infection, aggravating the patient's condition.

[0006] The equipment is separated from the monitoring system, and the operation is complicated: the existing ventricular drainage device is usually separated from the intracranial pressure monitoring device, which requires medical staff to frequently use multiple independent devices to obtain the patient's physiological parameters. This model not only increases the difficulty of equipment management, but also increases information delays, and medical staff cannot respond to abnormal situations that occur during the drainage process in a timely manner.

[0007] It is difficult to meet the personalized needs of patients: Due to the different conditions and changes in intracranial pressure of different patients, existing equipment cannot provide accurate drainage solutions for individual differences. For example, the intracranial pressure control requirements of children and adults are different, and existing equipment cannot automatically adapt to such differentiated needs, which may lead to insufficient or excessive drainage.

[0008] Based on the above problems, there is an urgent need for a new ventricular drainage device that can achieve precise drainage control, intelligent automatic adjustment, and antibacterial protection. This device should be able to monitor the patient's intracranial pressure and drainage fluid flow in real time, and automatically adjust the drainage speed according to real-time data to reduce the operating burden of medical staff and improve the patient's safety and postoperative recovery effect.

Obviously, the described embodiments are only part of the embodiments of the present invention.

[0032] Embodiment 1 is a preferred technical solution for a head ventricular drainage device.

[0033] The ventricular drainage device 1 includes a drainage flow control component 2 provided on the pipeline of the ventricular drainage device 1; the ventricular drainage device 1 includes a liquid storage bag 11, a guide tube 12 connected to the liquid inlet port of the liquid storage bag 11, the other end of the guide tube 12 is connected to a drainage bottle 16, and the liquid inlet port of the drainage bottle 16 is connected to a liquid inlet tube 14; the ventricular drainage device 1 also includes a ventricular puncture catheter 17, and a drainage tube 15 connected to the liquid outlet port of the ventricular puncture catheter 17;

[0034] The drainage flow control component 2 includes a shell 22, a servo drive motor 21 fixed on the outer surface of the shell 22, the output shaft of the servo drive motor 21 penetrates the inner cavity of the shell 22, one end of the output shaft of the servo drive motor 21 located in the inner cavity of the shell 22 is connected to a rotor 28, three groups of rollers 23 are rotatably connected on the outer ring surface of the rotor 28, three peristaltic tubes 24 are arranged at equal distances in the inner cavity of the shell 22, and the inner surface of the peristaltic tube 24 contacts the outer surface of the roller 23; two liquid collecting covers 26 are connected through the outer surface of the shell 22, and three connecting nozzles 27 located in the inner cavity of the shell 22 are fixed on the inner surface of the liquid collecting cover 26;

[0035] The connecting nozzle 27 at the bottom is respectively connected to the top end of the peristaltic tube 24, and the connecting nozzle 27 at the top is connected to the bottom end of the peristaltic tube 24; the top liquid collecting cover 26 is connected to the end of the drainage tube 15 away from the ventricular puncture catheter 17, and the bottom liquid collecting cover 26 is connected to the end of the liquid inlet tube 14 away from the drainage bottle 16.

[0036] The end of the drainage bottle 16 is fixedly connected with a liquid inlet port and a liquid discharge port, the liquid inlet port is connected to the end of the liquid inlet tube 14 away from the drainage flow control component 2, and the liquid discharge port is connected to the end of the diversion tube 12 away from the liquid storage bag 11. One end of the diversion tube 12 located inside the drainage bottle 16 extends deep into the inner cavity of the drainage bottle 16. A micro flow control valve 13 is installed on the pipeline of the liquid inlet tube 14.

[0037] The outer surface of the housing 22 is provided with a through hole for the output shaft of the servo drive motor 21 to pass through, and a sealed bearing is filled and fixed inside the through hole. The inner cavity side wall of the housing 22 is provided with three grooves of equal distance for the peristaltic tube 24 to be embedded; the outer surface of the liquid collecting cover 26 is connected with a joint 25, the bottom joint 25 is connected to the end of the drainage tube 15 away from the ventricular puncture catheter 17, and the bottom joint 25 is connected to the end of the inlet tube 14 away from the micro flow control valve 13.

[0038] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0039] After the ventricular puncture catheter 17 is located inside the ventricle, the cerebrospinal fluid is drained by the ventricular puncture catheter 17 and the drainage tube 15 to the top of the liquid collecting cover 26. At this time, the servo drive motor 21 drives the rotor 28 to rotate, and the roller 23 and the peristaltic tube 24 are squeezed back and forth to allow the cerebrospinal fluid inside the peristaltic tube 24 to be peristaltically transported to the bottom of the liquid collecting cover 26, and then the cerebrospinal fluid is transported to the drainage bottle 16 through the liquid inlet tube 14. After the cerebrospinal fluid passes through the micro flow control valve 13, the micro flow control valve 13 detects the flow rate and circulation speed, and controls the rotation speed of the servo drive motor 21 according to the set flow speed threshold, thereby controlling the circulation speed and flow of the cerebrospinal fluid.

[0040] Example 2: Dynamic control system based on intracranial pressure and flow

[0041] In this embodiment, the ventricular drainage device is equipped with a dynamic control system, which can intelligently adjust the flow rate and flow rate during the drainage process by linking with the intracranial pressure monitor and the flow sensor.

[0042] System composition: The system consists of a servo drive motor, an intracranial pressure monitor, a flow sensor and a central control module. The intracranial pressure monitor detects the patient's intracranial pressure level in real time, and the flow sensor measures the flow rate and flow of the drainage fluid.

[0043] Working principle: When the intracranial pressure exceeds the set safety range (such as intracranial hypertension caused by excessive cerebrospinal fluid), the control system will increase the speed of the servo drive motor, thereby increasing the flow rate of the drainage fluid and helping to reduce the intracranial pressure. When the intracranial pressure is detected to drop to normal levels or below the safety threshold, the control system will automatically slow down the motor speed and reduce the drainage speed to avoid secondary damage caused by excessive drainage.

[0044] Advantages: Through the adjustment of this intelligent system, automatic drainage can be achieved, and medical staff do not need to frequently adjust the drainage speed, which greatly reduces the complexity of the operation. At the same time, it can implement personalized drainage plans according to the patient's specific situation, greatly improving the safety and efficiency of the device.

[0045] Embodiment 3: Replaceable modular drainage tube design

[0046] This embodiment focuses on optimizing the drainage pipe part in the device and proposes a modular and replaceable drainage tube structure.

[0047] Modular design: The device's drainage tube 12 and drainage tube 15 are modularly designed. Each section of the tube is connected by a standardized quick connector, which is convenient for medical staff to quickly disassemble and replace as needed after surgery. This modular design makes the device more convenient during postoperative maintenance and cleaning, especially when there is a risk of pipeline damage or infection, the relevant parts can be quickly replaced to reduce the risk of postoperative infection.

[0048] Material selection: Both the drainage tube and the drainage tube are made of high-molecular antibacterial material. This material not only has good biocompatibility, but also has antibacterial function, which effectively reduces the possibility of bacterial growth during the drainage process and ensures the hygiene and safety of the device.

[0049] Advantages: Through modular design and the introduction of antibacterial materials, the service life and safety of the device are greatly improved, the possibility of postoperative infection is reduced, and the maintenance efficiency of the device is improved.

[0050] Example 4: Design of flexible ventricular puncture catheter

[0051] This embodiment optimizes the ventricular puncture catheter and designs a flexible ventricular puncture catheter that can better adapt to the ventricular structure and improve the drainage effect.

[0052] Catheter structure: The ventricle puncture catheter 17 is made of flexible material and has multiple drainage holes inside. These drainage holes are evenly distributed along the length of the catheter, making the drainage process more uniform and stable, and avoiding the sudden drop in local ventricular pressure or brain tissue damage caused by concentrated drainage.

[0053] Flexible features: The catheter adopts a flexible design and can be flexibly bent according to the different shapes and sizes of the patients' ventricles, ensuring that the drainage tube can be comfortably placed in the ventricle without exerting excessive pressure on the surrounding brain tissue, thereby reducing postoperative discomfort.

[0054] Advantages: Flexible catheters can adapt to more diverse patient needs and evenly drain through multiple drainage holes, further reducing possible complications during the drainage process and improving patient comfort and surgical safety.

[0055] Example 5: Design of a liquid storage bag with integrated pressure regulation

[0056] This embodiment improves the liquid storage bag 11 and provides a liquid storage bag with an automatic pressure regulation function.

[0057] Pressure sensor: A pressure sensor is integrated inside the liquid storage bag to monitor the pressure changes inside the bag in real time. When there is too much fluid in the liquid storage bag and the pressure sensor detects that the pressure exceeds the set upper limit, the drainage speed will be automatically adjusted through the central control system to ensure that the pressure inside the liquid storage bag is maintained within a safe range.

[0058] Automatic adjustment function: The system can automatically adjust the speed of the servo drive motor to control the operation of the peristaltic pump. If the pressure in the reservoir bag is too high, the system will slow down the operation of the peristaltic pump and delay the drainage; conversely, if the pressure is too low, the drainage speed will be accelerated.

[0059] Advantages: This embodiment can effectively prevent problems such as drainage fluid backflow or excessive drainage caused by excessive pressure in the fluid storage bag, and further improves the accuracy and safety of ventricular drainage through the automatic pressure adjustment system.

[0060] Example 6: Ventricular drainage device with remote monitoring and alarm functions

[0061] In order to further improve the intelligence and safety of the drainage device, this embodiment proposes a ventricular drainage device with remote monitoring and alarm functions.

[0062] Remote monitoring: Through the built-in wireless communication module, the device can transmit important data such as intracranial pressure, flow, and reservoir bag pressure to the doctor or nurse's monitoring terminal in real time. Medical staff can view the patient's drainage status in real time through a computer or mobile device and adjust the treatment plan based on the data.

[0063] Alarm system: The device has built-in multiple alarm mechanisms. When abnormal situations occur during the drainage process (such as too fast drainage, abnormal increase in intracranial pressure, overpressure in the fluid storage bag, etc.), the system will immediately trigger an audible or visual alarm and send an alarm message to relevant medical staff to ensure that the problem can be solved as soon as possible.

[0064] Advantages: The remote monitoring and alarm functions not only improve the intelligence level of the drainage device, but also greatly reduce the burden on medical staff and ensure real-time safety monitoring of postoperative patients during drainage.

[0065] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
