Abstract
Description
Technical Field
[0001] This utility model relates to a cranial perfusion and drainage system. Background Technology
[0002] Intracerebral hemorrhage, a serious cerebrovascular disease threatening human life and health, is characterized by high incidence, high disability rate, and high mortality rate. Currently, soft-channel therapy for intracerebral hemorrhage is widely used in clinical practice; however, some problems remain to be solved.
[0003] In the treatment of soft-channel intracranial hemorrhage, the main approach is to insert a soft tube into the cranium, relying on intracranial pressure to drain the hematoma. This method is inherently relatively passive. On one hand, continuous drainage typically needs to be maintained for 3-5 days. During this period, patients are highly susceptible to persistent bleeding, which activates clotting factors in the blood, causing blood clots. Once the blood clots, they severely hinder drainage. Passive drainage relying solely on intracranial pressure is insufficient to remove these clots, often requiring continuous infusion of urokinase during drainage, further prolonging the drainage time. Furthermore, if intracranial pressure is too high, brain tissue may shift from high-pressure to low-pressure areas, potentially leading to brain herniation. Brain herniation is an extremely dangerous condition, compressing vital structures such as the brainstem and causing severe consequences such as respiratory and cardiac arrest. Therefore, close monitoring of intracranial pressure is crucial, allowing for timely adjustments to drainage rates and other measures to prevent a rapid increase in intracranial pressure and thus prevent brain herniation.
[0004] On the other hand, prolonged placement of catheters in the brain inevitably increases the probability of pathogens such as bacteria invading the cranium, and the chance of infection increases exponentially with the extension of drainage time.
[0005] To ensure the best treatment outcome for soft-channel intracerebral hemorrhage, the irrigation and perfusion process is crucial. Appropriate irrigation and perfusion can, to some extent, prevent premature blood clotting, help maintain drainage patency, and promote hematoma drainage. However, the injection of irrigation fluid increases the intracranial load, so accurate measurement of intracranial pressure is vital throughout the entire treatment process.
[0006] Piezoelectric sensor technology has unique advantages in measuring intracranial pressure, providing doctors with real-time and accurate intracranial pressure data to help them better assess the condition and adjust treatment plans.
[0007] Questions such as how to achieve more precise irrigation control and how to further improve the accuracy and stability of intracranial pressure measurement have provided important basis for the research and improvement of this invention. Utility Model Content

[0009] This utility model is achieved through the following technical solution:
[0010] A cranial perfusion and drainage system includes a dual-peristaltic pump perfusion and drainage controller, a perfusion channel, a drainage channel, a perfusion bag, and a drainage waste fluid collector. One end of the perfusion channel is connected to the perfusion bag, and the other end of the perfusion channel passes through the dual-peristaltic pump perfusion and drainage controller and is inserted into the cranium to perfuse the intracranial cavity with perfusion fluid from the perfusion bag. One end of the drainage channel is inserted into the cranium, and the other end of the drainage channel passes through the dual-peristaltic pump perfusion and drainage controller and is connected to the drainage waste fluid collector. Under the pumping suction force generated by the dual-peristaltic pump perfusion and drainage controller, the waste fluid in the cranium is collected into the drainage waste fluid collector through the drainage channel.

[0018] Furthermore, the infusion cavity is provided with a first throttling valve, and the drainage cavity is provided with a second throttling valve.
[0019] Furthermore, the cranial perfusion irrigation and drainage system also includes a drainage hanging plate, which is vertically arranged, and the drainage waste liquid collector is located on the drainage hanging plate and can slide and adjust up and down on the drainage hanging plate.
[0020] Furthermore, the cranial perfusion irrigation and drainage system also includes a drainage support, which is vertically arranged, and the drainage hanging plate is disposed on the drainage support and can slide and adjust up and down on the drainage support.

[0048] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.
[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment discloses a cranial perfusion irrigation and drainage system, which includes a dual peristaltic pump perfusion and drainage controller 1, a perfusion channel 2, a drainage channel 3, a perfusion bag 4, and a drainage waste fluid collector 5. One end of the perfusion channel 2 is connected to the perfusion bag 4, and the other end of the perfusion channel 2 passes through the dual peristaltic pump perfusion and drainage controller 1 and is inserted into the cranium, so as to realize the perfusion fluid in the perfusion bag 4 to perfuse the cranium through the perfusion channel 2.
[0050] The perfusion bag 4, containing perfusion fluid for irrigation and flushing, passes through the perfusion channel 2 and the dual peristaltic pump perfusion and drainage controller 1, ensuring a smooth flushing process. The perfusion fluid in the perfusion bag 4 is then injected into the intracranial cavity through the perfusion channel 2. The dual peristaltic pump perfusion and drainage controller 1 provides power to the flowing perfusion fluid within the perfusion channel 2. By operating the dual peristaltic pump perfusion and drainage controller 1 synchronously, alternately, and at different rates, high, medium, and low perfusion and flushing pressures are achieved, making the drainage process active and effectively flushing out blood clots. Simultaneously, the dual peristaltic pump perfusion and drainage controller 1 provides a greater flow rate per unit time than a single peristaltic pump, preventing blood clot formation and avoiding damage to the brain parenchyma.
[0051] One end of the drainage channel 3 is inserted into the cranium, and the other end of the drainage channel 3 passes through the dual peristaltic pump irrigation and drainage controller 1 and is connected to the drainage waste fluid collector 5. Under the pumping and suction force generated by the dual peristaltic pump irrigation and drainage controller 1, the waste fluid in the cranium is collected into the drainage waste fluid collector 5 through the drainage channel 3.
[0052] The intracranial waste fluid flows through the drainage channel 3 and passes through the dual peristaltic pump irrigation and drainage controller 1. The waste fluid flows through the drainage channel 3 into the waste fluid collector 5. The dual peristaltic pump irrigation and drainage controller 1 provides power to the flowing waste fluid within the drainage channel 3. By changing the passive drainage method, which relies on intracranial pressure, to an active drainage method using the dual peristaltic pump irrigation and drainage controller 1, the drainage efficiency is increased, and intracranial pressure can be rapidly reduced. Furthermore, the dual peristaltic pump irrigation and drainage controller 1 achieves greater thrust than a single peristaltic pump while maintaining effective drainage.
[0053] The dual-peristaltic pump irrigation and drainage controller 1 includes a body 11 and dual peristaltic pumps 12. The dual peristaltic pumps 12 are located within the body 11, and both the irrigation channel 2 and the drainage channel 3 pass through the body 11. The dual peristaltic pumps 12 can exert pressure on the irrigation channel 2 and the drainage channel 3 in the same or opposite directions. During drainage treatment, depending on different drainage needs—sometimes requiring high thrust, sometimes requiring continuous low thrust to maintain intracranial pressure—the dual peristaltic pumps 12 can act in the same or opposite directions. By exerting pressure on the irrigation channel 2 and the drainage channel 3 in the same or opposite directions, the fluid pressure within the irrigation channel 2 and the drainage channel 3 increases, thereby achieving irrigation and drainage. Simultaneously, the body 11 provides protection, and housing the dual peristaltic pumps 12 within the body 11 ensures more stable and reliable operation.
[0054] In this embodiment, the dual peristaltic pump 12 includes a drive motor, a first peristaltic pump rotor 121, and a second peristaltic pump rotor 122. Both the first peristaltic pump rotor 121 and the second peristaltic pump rotor 122 are located inside the body 11. The drive motor is connected to the first peristaltic pump rotor 121 and the second peristaltic pump rotor 122 and is used to drive the rotation of the first peristaltic pump rotor 121 and the second peristaltic pump rotor 122. Both the first peristaltic pump rotor 121 and the second peristaltic pump rotor 122 exert a squeezing effect on the infusion cavity 2. The first peristaltic pump rotor 121 exerts a squeezing effect on the drainage cavity 3. The second peristaltic pump rotor 122 does not contact the drainage cavity 3.
[0055] Specifically, a drive motor provides the driving force, with both the first peristaltic pump rotor 121 and the second peristaltic pump rotor 122 driven by a rear-mounted drive motor. The infusion chamber 2, located in the upper layer, passes through the first peristaltic pump rotor 121, enters the second peristaltic pump rotor, and finally passes outside the body 11, exiting into the intracranial cavity. The drainage chamber 3, passing inside the body 11, is positioned below the first peristaltic pump rotor 121 and is only subjected to the individual squeezing force of the first peristaltic pump rotor 121. The dual peristaltic pump infusion and drainage controller 1, by employing two peristaltic pumps, can simultaneously generate infusion and flushing fluid flows, achieving high and low pressure irrigation. One set of peristaltic pumps is connected to the drainage chamber 3 to increase the drainage rate. Simultaneously, the first peristaltic pump rotor 121 and the second peristaltic pump rotor 122 can act in the same direction or in opposite directions.
[0056] The dual peristaltic pump infusion and drainage controller 1 also includes a controller electrically connected to it. The controller is used to control the dual peristaltic pump infusion and drainage controller 1, achieving high safety and stability. The dual peristaltic pump infusion and drainage controller 1 can control the output flow rate and velocity by controlling the rotor speed and adjusting the pressure of the rotor on the infusion chamber 2 and drainage chamber 3. After the first peristaltic pump rotor 121 starts, the liquid pressure between the first peristaltic pump rotor 121 and the second peristaltic pump rotor 122 increases. The opening of the second peristaltic pump rotor 122 creates a certain release effect, accelerating the flow of the infusion liquid. Conversely, the liquid flow rate can be increased without increasing the infusion pressure by interpolating the movement gap between the two rotors.
[0057] The cranial perfusion and drainage system also includes an intracranial pressure sensor 6. One end of the intracranial pressure sensor 6 extends into the cranium to detect intracranial pressure, and the other end is electrically connected to the dual peristaltic pump perfusion and drainage controller 1. The intracranial pressure sensor 6 is installed at the tip of the catheter and inserted into the cranium. The rear end of the intracranial pressure sensor 6 is connected to a signal communication port to achieve real-time measurement of intracranial pressure. The intracranial pressure sensor 6 detects intracranial pressure in real time and transmits the detected intracranial pressure signal to the controller. The controller uses the detected intracranial pressure to control the rotation speed of the dual peristaltic pump perfusion and drainage controller 1, thereby achieving perfusion and drainage pressure control settings in the perfusion channel 2 and drainage channel 3. By measuring intracranial pressure through the intracranial pressure sensor 6, perfusion pressure monitoring is achieved, increasing closed-loop control of the pump and realizing closed-loop control for intracranial pressure balance.
[0058] The dual-peristaltic pump perfusion and drainage controller 1 also includes a first monitor 13, which is located between the dual-peristaltic pump 12 and the intracranial cavity, and is electrically connected to the dual-peristaltic pump 12. The first monitor 13 can be a flow monitor or a pressure monitor. The first monitor 13 is used to detect the flow rate and / or pressure in the perfusion cavity 2 in real time. The first monitor 13 transmits the detected signal to the controller, which controls the rotation speed of the dual-peristaltic pump perfusion and drainage controller 1, thereby realizing the setting of perfusion flow rate and / or pressure control on the perfusion cavity 2. It can accurately regulate the perfusion process and monitor the specific flow rate and / or pressure during the perfusion process, greatly improving the stability and control accuracy of the cranial perfusion irrigation and drainage system.
[0059] In this embodiment, the first monitor 13 is located inside the body 11. Placing the first monitor 13 inside the body 11 results in higher stability.
[0060] The dual peristaltic pump irrigation and drainage controller 1 also includes a second monitor 14, which is located between the dual peristaltic pump 12 and the drainage waste collector 5. The second monitor 14 is located in the drainage channel 3 and is used to detect the flow rate within the drainage channel 3. The second monitor 14 is electrically connected to the dual peristaltic pump 12. The second monitor 14 can be a flow rate monitor or a pressure monitor. The second monitor 14 is used to detect the flow rate and / or pressure within the drainage channel 3 in real time. The drainage channel 3 transmits the detected signal to the controller, which is used to control the rotation speed of the dual peristaltic pump irrigation and drainage controller 1, thereby enabling the setting of drainage flow rate and / or pressure control on the drainage channel 3. This allows for precise regulation of the drainage process and monitoring of the specific flow rate and / or pressure during the drainage process, greatly improving the stability and control accuracy of the cranial irrigation and drainage system.
[0061] In this embodiment, the second monitor 14 is located inside the body 11. Placing the second monitor 14 inside the body 11 provides greater stability.
[0062] In this embodiment, a first throttle valve 15 is provided on the infusion channel 2, and the first throttle valve 15 is arranged at the outlet position of the infusion channel 2 in the body 11. A second throttle valve 16 is provided on the drainage channel 3, and the second throttle valve 16 is arranged at the outlet position of the drainage channel 3 in the body 11.
[0063] The cranial perfusion irrigation and drainage system also includes a drainage mounting plate 7, which is vertically positioned. A waste drainage collector 5 is mounted on the mounting plate 7 and can slide and adjust up and down. The waste drainage collector 5 can be adjusted vertically according to the patient's position. By sliding the waste drainage collector 5 up and down on the mounting plate 7, the height of the waste drainage collector 5 can be precisely adjusted to meet drainage needs under different intracranial pressure conditions, ensuring both drainage effectiveness and patient safety.
[0064] The cranial perfusion and irrigation drainage system also includes a drainage support 8, which is vertically positioned. A drainage hanging plate 7 is mounted on the drainage support 8 and can slide and adjust up and down. A dual peristaltic pump perfusion and drainage controller 1 is fixed to the drainage support 8. An infusion bag 4 provides perfusion fluid and is fixed to the drainage support 8. The drainage hanging plate 7 slides and adjusts up and down on the drainage support 8, which in turn moves the drainage waste fluid collector 5 up and down. The drainage hanging plate 7 can be adjusted up and down according to the patient's position, allowing the drainage waste fluid collector 5 to slide and adjust up and down according to intracranial pressure. This allows for precise adjustment of the height of the drainage waste fluid collector 5 to adapt to drainage needs under different intracranial pressure conditions, ensuring drainage effectiveness while protecting patient safety. This system enables the cranial perfusion and irrigation drainage system to combine infusion, drainage, and drainage height adjustment functions.
[0065] The drainage waste fluid collector 5 includes a drainage collection bottle 51 and a drainage waste fluid collection bag 52. The drainage collection bottle 51 is slidably mounted on a drainage mounting plate 7. The top and bottom of the drainage collection bottle 51 are connected to the drainage channel 3 and the drainage waste fluid collection bag 52, respectively. The drainage mounting plate 7 can be adjusted up and down according to the patient's position, and the drainage collection bottle 51 can be adjusted up and down according to intracranial pressure. The drainage waste fluid collection bag 52 is fixed to the drainage collection bottle 51 and moves accordingly. The waste fluid will flow through the drainage channel 3 into the drainage collection bottle 51 and finally into the drainage waste fluid collection bag 52.
[0066] The perfusion process begins at the perfusion bag 4. The perfusion fluid flows from the bag along the perfusion channel 2, then enters the dual peristaltic pump perfusion and drainage controller 1. Under the action of the controller 1, the fluid continues its journey, successfully reaching the intracranial cavity through the perfusion channel 2. Once inside the cranium, the intracranial hematoma is irrigated. After irrigation, the waste fluid is discharged through the drainage channel 3 under the pumping suction force generated by the controller 1. The waste fluid flows along a predetermined path and is eventually collected in the drainage waste collection bag 52, thus completing the entire perfusion, irrigation, and drainage process.
[0067] Among them, the infusion bag 4 and the drainage waste liquid collection bag 52 are both welded by high frequency welding. The infusion cavity 2 and the drainage cavity 3 are both made of silicone extrusion and injection molding and then bonded by RTV glue. The drainage bracket 8 is made by machining. The remaining pipes are composed of extrusion or injection molding.
[0068] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
