Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to an active flushing and drainage system and a control method. Background Art

[0002] External Ventricular Drain (EVD) is an important neurosurgical technique used to treat increased intracranial pressure caused by conditions such as intraventricular hematoma and hydrocephalus. This surgery is usually performed by placing a drainage tube into the patient's ventricles. The drainage tube is connected to an external drainage system, and excess cerebrospinal fluid is drained out of the body through the drainage tube, thereby relieving intracranial pressure. However, drainage tube blockage is one of its common and serious complications. Drainage tube blockage may be caused by a variety of factors, including blood clots, pus clots, protein coagulation, and other tissue debris. Drainage tube blockage leads to poor drainage, which may lead to increased intracranial pressure, accumulation of blood and other fluids in the brain, and increase the patient's risk of worsening of the condition and complications.

[0003] Drainage tube blockage is closely related to surgical operation, tube design, and tube material. Although modern medical technology has improved the quality and design of drainage tubes, there is still a risk of drainage tube blockage in actual applications. This problem not only increases the complexity and pain of patient treatment, but may also prolong hospitalization, increase medical expenses, and increase the risk of complications such as infection.

[0004] Existing technologies mainly rely on medical staff to regularly monitor the patient's intracranial pressure and observe the drainage status. After confirming that the tube is blocked, medical staff manually inject liquid into the patient's ventricle to flush the blocked channel. Then, through manual observation, the unblocking condition is identified to decide whether to inject liquid again to unblock or replace the drainage tube. However, this method requires regular manual monitoring, which may miss the best time to unblock the blockage, and then require additional surgery to replace the drainage tube, resulting in delayed treatment. Summary of the invention

[0005] In order to solve the problem that the prior art does not identify and handle tube blockage in a timely manner, resulting in delayed patient treatment, the present application provides an active flushing and drainage system and a control method.

[0006] In the first aspect, the present application provides an active flushing and drainage system, which adopts the following technical solutions:

[0007] An active flushing and drainage system, comprising: a perfusion unit, a flushing unit, a drainage unit, an interactive control unit and a drainage tube;

[0008] The interactive control unit is used to monitor whether the drainage tube is blocked;

[0009] The drainage tube is used to connect the perfusion unit and the drainage unit to the patient's cerebral ventricle respectively;

[0010] The perfusion unit is used to perfuse the patient's cerebral ventricle through the drainage tube; the drainage unit is used to drain the patient's cerebral ventricle through the drainage tube;

[0011] The flushing unit is used to remove the blockage of the drainage tube when the interactive control unit detects that the drainage tube is blocked.

[0012] By adopting the above technical solution, the interactive control unit monitors whether the drainage tube is blocked, so as to detect the problem in time and avoid medical accidents caused by blockage. When blockage does not occur, conventional perfusion and drainage are performed through the perfusion unit and the drainage unit to ensure the treatment effect. When blockage is detected, the unit switches to the flushing unit, and the liquid in the liquid storage bag flushes the blocked drainage tube orifice with an instantaneous high pressure to achieve flushing in cranial drainage, thereby reducing the risk of poor drainage caused by blockage of intracranial hematoma or tissue or sediment, avoiding poor treatment effect or drainage tube replacement surgery caused by blockage, reducing additional medical costs and infection risks, improving patient prognosis, and reducing nursing costs.

[0013] In a preferred example, the present application may be further configured as follows: the interactive control unit includes an input module, a processing controller and a display module;

[0014] The input module is used to receive instructions input by the user and send the instructions to the processing controller;

[0015] The processing controller is used to receive an intracranial pressure parameter and a drainage passage flow parameter, select a corresponding preset parameter according to the instruction, and determine whether the drainage tube is blocked according to the intracranial pressure parameter, the drainage passage flow parameter and the preset parameter;

[0016] The display module is used to display the intracranial pressure parameters and drainage pathway flow parameters received by the processing controller.

[0017] By adopting the above technical solution, the input module is used for users to set preset parameters. The personalized parameter settings make the system more in line with the actual needs of patients, improve the targetedness and personalization of treatment, use intracranial pressure sensors to monitor the intracranial pressure of the patient's ventricles, and use liquid flow meters to monitor the flow of the drainage path, which helps to accurately assess the drainage status and automatically detect the risk of tube blockage. The intuitive data display method of the display module enables medical staff to quickly understand the status of the patient's ventricles, thereby improving work efficiency.

[0018] In a preferred example, the present application may be further configured as follows: the preset parameters include a preset intracranial pressure upper limit and a preset flow rate lower limit;

[0019] The processing controller is used to compare the intracranial pressure parameter with the preset upper limit of intracranial pressure, and to compare the drainage passage flow with the preset lower limit of flow. If the intracranial pressure parameter is higher than the preset upper limit of intracranial pressure and the drainage passage flow is lower than the preset lower limit of flow, it is determined that the drainage tube is blocked.

[0020] By adopting the above technical solution, when the intracranial pressure parameter is higher than the preset intracranial pressure upper limit and the drainage path flow is lower than the preset flow lower limit, the processing controller will determine that the drainage tube is blocked, thereby reducing complications caused by untimely discovery of blockage and improving the efficiency of identifying drainage tube blockage.

[0021] In a preferred example, the present application can be further configured as follows: the interactive control unit is also used to control the perfusion unit to perform perfusion with a perfusion amount set by the user if the intracranial pressure parameter is judged to be lower than the upper limit of the preset intracranial pressure range when blockage of the drainage tube is not detected, and to control the drainage unit to perform drainage with a drainage amount set by the user if the intracranial pressure parameter is judged to be higher than the lower limit of the preset intracranial pressure range.

[0022] By adopting the above technical solution, when no blockage of the drainage tube is detected, the perfusion unit and the drainage unit are controlled to execute the normal perfusion and drainage mode, ensuring that the fluid in the patient's ventricles can be diluted and discharged normally, thereby ensuring the treatment effect.

[0023] In a preferred example, the present application may be further configured as follows: the flushing unit includes a liquid storage bag, and the liquid release pipeline of the liquid storage bag is connected to the drainage tube;

[0024] The liquid storage bag releases the liquid accumulated in the liquid storage bag under the control of the interactive control unit to relieve the blockage of the drainage tube.

[0025] By adopting the above technical solution, the liquid accumulated in the liquid storage bag is flushed at a higher pressure, thereby relieving the blockage of the drainage tube, ensuring that the blockage can be dealt with in time, and avoiding complications caused by prolonged blockage.

[0026] In a preferred example, the present application may be further configured as follows: the perfusion unit includes a perfusion liquid bag, a peristaltic pump, and a perfusion passage switch;

[0027] The peristaltic pump, under the control of the interactive control unit, peristaltically moves the liquid in the perfusion liquid bag connected to one end of the peristaltic pump into the liquid storage bag connected to the other end of the peristaltic pump, so that the liquid storage bag accumulates liquid;

[0028] Wherein, the filling unit and the flushing unit meet any of the following connection modes:

[0029] Mode 1: One end of the liquid storage bag is connected to the peristaltic pump, and the other end is connected to the perfusion passage switch;

[0030] Method 2: The flushing unit also includes a flushing pathway switch, the perfusion pathway switch and the first end of the liquid storage bag are both connected to the peristaltic pump, the second end of the liquid storage bag is connected to the first end of the flushing pathway switch, and the second ends of the perfusion pathway switch and the flushing pathway switch are both connected to the first channel of the drainage tube.

[0031] By adopting the above technical solution, for the connection mode in which the flushing unit is connected in series with the perfusion unit, if no blockage is detected, pressure will not accumulate in the liquid storage bag, and will not affect the perfusion pressure and perfusion volume, and will not affect the normal perfusion and drainage cycle. For the connection mode in which the flushing unit and the perfusion unit are connected in parallel, the perfusion passage and the flushing passage are isolated, and the process of accumulating pressure in the liquid storage bag will not affect the normal perfusion and drainage cycle, thereby improving the convenience and stability of control.

[0032] In a preferred example, the present application may be further configured as follows: the drainage unit includes a drainage passage switch and a drainage bag;

[0033] One end of the drainage passage switch is connected to the second channel of the drainage tube, and the other end is connected to the drainage bag, so that the fluid in the patient's cerebral ventricle is drained to the drainage bag through the drainage passage switch.

[0034] By adopting the above technical solution, the drainage unit can flexibly adjust the drainage speed and flow rate through the drainage passage switch control to ensure the smooth progress of the drainage process.

[0035] In a preferred example, the present application can be further configured as follows: the flushing unit further includes a pressure relief switch; one end of the pressure relief switch is connected to the liquid storage bag of the flushing unit, and the other end is connected to the drainage bag;

[0036] The pressure relief switch is used to open under the control of the interactive control unit when the pressure of the liquid storage bag exceeds the preset flushing pressure, so that the liquid in the liquid storage bag can be drained to the drainage bag through the pressure relief switch, until the pressure of the liquid storage bag does not exceed the preset flushing pressure, and the pressure relief switch is closed under the control of the interactive control unit.

[0037] By adopting the above technical solution and using the pressure relief switch to adjust the pressure of the liquid storage bag, it is possible to ensure that the pressure of the liquid storage bag meets the flushing requirements and avoid excessive pressure accumulated in the liquid storage bag. When the pressure in the liquid storage bag exceeds the preset flushing pressure, the pressure relief switch is opened to discharge excess liquid into the drainage bag to reduce the pressure, thereby ensuring that the pressure in the liquid storage bag meets the flushing requirements and improving the accuracy and safety of flushing.

[0038] In a preferred example, the present application may be further configured as follows: the flushing unit includes a perfusion passage switch and a drainage passage switch;

[0039] The interactive control unit is further used to control the perfusion unit and the drainage unit to perform enhanced perfusion and drainage operations alternately according to a preset rhythm when the drainage tube is blocked;

[0040] Among them, the enhanced perfusion and drainage operation is performed alternately according to a preset rhythm, including: after the perfusion pathway switch is opened and the drainage pathway switch is closed for continuous perfusion for a first preset time period, the perfusion pathway switch is closed and the drainage pathway switch is opened to drain the fluid in the patient's ventricles into the drainage bag and continue drainage for a second preset time period, and the operations are performed alternately in sequence.

[0041] By adopting the above technical solution, when the drainage tube is blocked, the blockage can be quickly and effectively relieved by the automatically controlled perfusion unit and drainage unit alternately performing perfusion and drainage operations according to a preset rhythm, thereby improving the efficiency of blockage treatment.

[0042] In a second aspect, the present application provides an active flushing and drainage control method, which adopts the following technical solution:

[0043] Monitor drainage tube for blockage;

[0044] Controlling the perfusion unit and the drainage unit connected to the drainage tube to perfuse the patient's cerebral ventricles, and controlling the drainage unit connected to the drainage tube to drain the patient's cerebral ventricles;

[0045] When it is detected that the drainage tube is blocked, the flushing unit is controlled to release the blockage of the drainage tube.

[0046] In a third aspect, the present application provides a computer program product, which adopts the following technical solution:

[0049] one or more processors;

[0050] Memory;

[0051] At least one application, wherein the at least one application is stored in a memory and configured to be executed by at least one processor, and the at least one application is configured to: execute the active irrigation and drainage control method as described in the second aspect.

If personal information is involved in the embodiments, the acquisition of all personal information needs to obtain the consent of the individual. If sensitive information is involved, the separate consent of the information subject needs to be obtained. The embodiments also need to be implemented with the authorization and consent of the object.

[0067] The present application embodiment provides an active flushing and drainage system, such as Figure 1 As shown, the system includes: an infusion unit, a flushing unit, a drainage unit, an interactive control unit and a drainage tube.

[0068] Specifically, the perfusion unit includes a perfusion liquid bag, a peristaltic pump and an intracranial pressure sensor. The intracranial pressure sensor is used to monitor the intracranial pressure of the patient, obtain intracranial pressure parameters and send them to the interactive control unit. The drainage unit includes a drainage bag and a liquid flow meter. The liquid flow meter is used to obtain the liquid flow out of the patient's ventricles, obtain the drainage path flow parameters and send them to the interactive control unit. The drainage bag is used to receive the liquid drained from the patient's ventricles. The interactive control unit includes a processing controller, which is used to receive the intracranial pressure parameters and drainage path flow parameters sent by the perfusion unit and the drainage unit, and determine whether the drainage tube is blocked based on the intracranial pressure parameters and the drainage path flow parameters.

[0069] The drainage tube can be a double-lumen drainage tube or a multi-lumen drainage tube. The drainage tube contains at least two channels. One end of the first channel is connected to the perfusion unit, and the other end is connected to the patient's ventricle. The perfusion unit can perfuse liquid into the patient's ventricle through the first channel and the drainage hole when needed. One end of the second channel is connected to the patient's ventricle, and the other end is connected to the drainage unit. The drainage unit can drain the liquid in the patient's ventricle through the drainage hole and the second channel when needed. When the interactive control unit does not detect that the drainage tube is blocked, it is in the normal perfusion and drainage mode, the flushing unit does not operate, the perfusion unit perfuses at the perfusion volume set by the user when the intracranial pressure parameters reach the perfusion conditions, and the drainage unit drains at the drainage volume set by the user when the intracranial pressure parameters reach the drainage conditions.

[0070] The flushing unit includes a liquid storage bag. The flushing unit can be connected in series or in parallel with the perfusion unit. When the interactive control unit detects that the drainage tube is blocked, the normal perfusion and drainage mode is switched to the flushing mode, the channel between the liquid storage bag and the patient's ventricle is closed, and the perfusion liquid bag is used to perfuse liquid into the liquid storage bag. After the liquid storage bag reaches the preset flushing pressure, the channel between the liquid storage bag and the patient's ventricle is opened, and the liquid in the liquid storage bag flows into the drainage tube. The larger perfusion passage pressure impacts the blockage of the drainage hole, thereby clearing the blocked drainage hole.

[0071] The embodiment of the present application monitors whether the drainage tube is blocked by an interactive control unit, so that problems can be discovered in time to avoid medical accidents caused by blockage. When blockage does not occur, conventional perfusion and drainage are performed through the perfusion unit and the drainage unit to ensure the treatment effect. When blockage is detected, the flushing unit is switched to the flushing unit, and the liquid in the liquid storage bag flushes the blocked drainage tube orifice with an instantaneous high pressure to achieve flushing in cranial drainage, reducing the risk of poor drainage caused by intracranial hematoma or tissue or sediment blockage, avoiding poor treatment effect or drainage tube replacement surgery caused by blockage, reducing additional medical costs and infection risks, improving patient prognosis, and reducing nursing costs. The present application can detect and deal with blockage in time, improving treatment efficiency.

[0072] In a possible implementation of the embodiment of the present application, the interaction control unit includes an input module, a processing controller and a display module;

[0073] An input module, used for receiving instructions input by a user and sending the instructions to a processing controller;

[0074] A processing controller, used to receive intracranial pressure parameters and drainage path flow parameters, select corresponding preset parameters according to instructions, and determine whether the drainage tube is blocked according to the intracranial pressure parameters, drainage path flow parameters and preset parameters;

[0075] The display module is used to display the intracranial pressure parameters and drainage path flow parameters received by the processing controller.

[0076] In this embodiment, the interactive control unit may also include an input module, and the medical staff inputs instructions containing preset parameters through the interactive interface of the input module. The specific values ​​of each preset parameter can be set by the medical staff based on clinical experience and medical knowledge, and this embodiment does not specifically limit it. The preset parameters include the intracranial pressure monitoring frequency. The processing controller receives the intracranial pressure monitoring frequency input by the user, and generates a corresponding control signal to send to the intracranial pressure sensor, so that the intracranial pressure sensor monitors according to the intracranial pressure monitoring frequency, and uploads the obtained intracranial pressure parameters to the processing controller. The liquid flow meter is connected to the drainage bag to obtain the drainage path flow parameters flowing out of the patient's ventricle and into the drainage bag, and sends the drainage path flow parameters to the processing controller.

[0077] In the embodiment of the present application, the input module is used for the user to set preset parameters. The personalized parameter setting makes the system more in line with the actual needs of the patient, improves the targetedness and personalization of the treatment, uses an intracranial pressure sensor to monitor the intracranial pressure of the patient's ventricle, and uses a liquid flow meter to monitor the flow of the drainage path, which helps to accurately assess the drainage status and automatically detect the risk of tube blockage. The intuitive data display method of the display module enables medical staff to quickly understand the patient's ventricular status and improve work efficiency.

[0078] In a possible implementation of the embodiment of the present application, the preset parameters include a preset intracranial pressure upper limit and a preset flow rate lower limit;

[0079] The processing controller is used to compare the intracranial pressure parameter with the preset intracranial pressure upper limit, and to compare the drainage path flow with the preset flow lower limit. If the intracranial pressure parameter is higher than the preset intracranial pressure upper limit and the drainage path flow is lower than the preset flow lower limit, it is determined that the drainage tube is blocked.

[0080] Among them, if the intracranial pressure parameter is not higher than the preset intracranial pressure upper limit and the drainage path flow parameter is not lower than the preset flow lower limit, it is determined that the drainage tube is not blocked. If the intracranial pressure parameter is higher than the preset intracranial pressure upper limit and the drainage path flow parameter is lower than the preset flow lower limit, it is determined that blockage has occurred. The display module displays information such as intracranial pressure parameters and drainage path flow to medical staff, and can also be used to receive and display the judgment result of whether blockage has occurred sent by the processing controller. When blockage occurs, the display module can be used to prompt the medical staff and terminate the normal perfusion and drainage mode until the medical staff confirms that there is no blockage and can manually start the normal perfusion and drainage mode.

[0081] In the embodiment of the present application, when the intracranial pressure parameter is higher than the preset intracranial pressure upper limit and the drainage path flow is lower than the preset flow lower limit, the processing controller will determine that the drainage tube is blocked, thereby reducing complications caused by untimely discovery of blockage and improving the efficiency of identifying drainage tube blockage.

[0082] In a possible implementation of the embodiment of the present application, the flushing unit includes a liquid storage bag, and a liquid release pipeline of the liquid storage bag is connected to the drainage tube;

[0083] The liquid storage bag is used to release the liquid accumulated in the liquid storage bag under the control of the interactive control unit to relieve the blockage of the drainage tube when the drainage tube is blocked.

[0084] In this embodiment, the perfusion unit includes a perfusion liquid bag and a peristaltic pump, one end of the peristaltic pump is connected to the perfusion liquid bag, and the other end is connected to the liquid storage bag, which is used to promote the flow of liquid in the perfusion liquid bag. The flushing unit also includes a liquid storage bag pressure sensor. The preset parameters also include a preset flushing pressure, which can be set by medical staff through the input module of the interactive control unit and sent to the processing controller. When the interactive control unit detects that the drainage tube is blocked, the normal perfusion and drainage mode is changed to the flushing mode, and the peristaltic pump peristalsizes the liquid in the perfusion liquid bag into the liquid storage bag. When the liquid pressure in the liquid storage bag reaches the preset flushing pressure, the liquid accumulated in the liquid storage bag is injected into the blocked drainage tube to flush the blockage at the drainage hole.

[0085] The embodiment of the present application uses the liquid accumulated in the liquid storage bag to flush at a relatively high pressure, thereby relieving the blockage of the drainage tube, ensuring that the blockage can be dealt with in a timely manner, and avoiding complications caused by prolonged blockage.

[0086] In a possible implementation of the embodiment of the present application, the perfusion unit includes a perfusion liquid bag, a peristaltic pump and a perfusion passage switch;

[0087] The peristaltic pump, under the control of the interactive control unit, peristaltically moves the liquid in the perfusion liquid bag connected to one end of the peristaltic pump into the liquid storage bag connected to the other end of the peristaltic pump, so that the liquid storage bag accumulates the liquid;

[0088] The filling unit and the flushing unit meet any of the following connection modes:

[0089] Method 1: One end of the liquid storage bag is connected to the peristaltic pump, and the other end is connected to the perfusion path switch, and the perfusion path switch is closed under the control of the interactive control unit;

[0090] Method 2: The flushing unit also includes a flushing passage switch, the first end of the perfusion passage switch and the liquid storage bag are both connected to the peristaltic pump, the second end of the liquid storage bag is connected to the first end of the flushing passage switch, and the second ends of the perfusion passage switch and the flushing passage switch are both connected to the first channel of the drainage tube.

[0091] Specifically, the flushing unit includes a liquid storage bag and a liquid storage bag pressure sensor, and the perfusion unit includes a perfusion liquid bag, a peristaltic pump, a perfusion channel switch and an intracranial pressure sensor.

[0092] For the interactive control unit, its processing controller is used to obtain parameters of the input module, liquid storage bag pressure sensor, intracranial pressure sensor and liquid flow meter, control the opening and closing of the perfusion pathway switch, drainage pathway switch and flushing pathway switch, control the operation of the peristaltic pump and the display module for display.

[0093] See also Figure 2 , which shows a schematic diagram of the first connection mode provided by an embodiment of the present application. The flushing unit is connected in series in the perfusion unit. In the flushing mode, the interactive control unit controls the perfusion passage switch to close, and controls the peristaltic pump to work to perfuse the liquid in the perfusion liquid bag into the liquid storage bag. After the pressure of the liquid storage bag reaches the preset flushing pressure, the interactive control unit sends an instruction to control the perfusion passage switch to open, and the liquid in the liquid storage bag is injected into the drainage tube through the perfusion passage switch to flush the blockage of the drainage hole. During the above flushing process, whether the drainage passage switch is opened or not is not limited.

[0094] See also Figure 3 , which shows a schematic diagram of the second connection method provided in an embodiment of the present application. The flushing unit is connected in parallel with the perfusion unit, and the flushing unit also includes a flushing passage switch. In the normal perfusion and drainage mode, the flushing passage switch is closed and the flushing unit does not work. Before flushing, the interactive control unit controls the peristaltic pump to perfuse the liquid in the perfusion liquid bag into the liquid storage bag until the pressure of the liquid storage bag reaches the preset flushing pressure. The process of accumulating pressure in the liquid storage bag does not affect the working state of the perfusion unit and the drainage unit, that is, whether the perfusion passage switch and the drainage passage switch are turned on or not is not limited; during flushing, the interactive control unit sends instructions to control the perfusion passage switch to close and the flushing passage switch to open, and the liquid in the liquid storage bag is injected into the drainage tube through the flushing passage switch to flush the blockage at the drainage tube.

[0095] In the embodiment of the present application, for the connection mode in which the flushing unit is connected in series with the perfusion unit, if no tube blockage is detected, no pressure will be accumulated in the liquid storage bag, and no influence will be exerted on the perfusion pressure and perfusion volume, and no influence will be exerted on the normal perfusion and drainage cycle. The perfusion passage switch will be closed only when the tube blockage is detected, and pressure will be accumulated in the liquid storage bag. For the connection mode in which the flushing unit and the perfusion unit are connected in parallel, the perfusion passage and the flushing passage are isolated, and the liquid storage bag can accumulate pressure at any time. The process of accumulating pressure will not affect the normal perfusion and drainage cycle, thereby improving the convenience and stability of control.

[0096] In a possible implementation of the embodiment of the present application, the drainage unit includes a drainage passage switch and a drainage bag;

[0097] One end of the drainage passage switch is connected to the second channel of the drainage tube, and the other end is connected to the drainage bag, so that the fluid in the patient's ventricle is drained to the drainage bag through the drainage passage switch.

[0098] Specifically, the drainage passage switch is used to control the operation of the drainage unit. When the drainage passage switch is turned on, the drainage unit works, and the fluid in the patient's ventricle flows into the drainage bag through the second channel of the drainage tube. When the drainage passage switch is closed, the drainage unit does not work.

[0099] In the embodiment of the present application, the drainage unit is controlled by the drainage passage switch, and the drainage speed and flow rate can be flexibly adjusted to ensure the smooth progress of the drainage process.

[0100] In a possible implementation of the embodiment of the present application, the flushing unit further includes a pressure relief switch; one end of the pressure relief switch is connected to the liquid storage bag of the flushing unit, and the other end is connected to the drainage bag;

[0101] The pressure relief switch is used to open under the control of the interactive control unit when the pressure in the liquid storage bag exceeds the preset flushing pressure, so that the liquid in the liquid storage bag can be drained to the drainage bag through the pressure relief switch until the pressure in the liquid storage bag does not exceed the preset flushing pressure, and the pressure relief switch is closed under the control of the interactive control unit.

[0102] For the first connection mode or the second connection mode, the system can also be provided with a pressure relief switch between the liquid storage bag and the drainage bag, see Figure 4 , which shows a schematic diagram of the pressure relief switch corresponding to the first connection mode provided in an embodiment of the present application. The processing controller is also used to control the opening and closing of the pressure relief switch. In the flushing mode, the pressure relief switch is closed first, and the processing controller of the interactive control unit controls the peristaltic pump to continue to run and continuously pump liquid into the liquid storage bag. When the pressure of the liquid storage bag exceeds the preset flushing pressure, the processing controller sends an opening instruction to the pressure relief switch, and the liquid storage bag directly discharges excess liquid into the drainage bag.

[0103] The embodiment of the present application utilizes a pressure relief switch to adjust the pressure of the liquid storage bag, thereby ensuring that the pressure of the liquid storage bag meets the flushing requirements and avoiding excessive pressure accumulated in the liquid storage bag. When the pressure in the liquid storage bag exceeds the preset flushing pressure, the pressure relief switch is opened to discharge excess liquid into the drainage bag to reduce the pressure, thereby ensuring that the pressure in the liquid storage bag meets the flushing requirements and avoiding damage to human tissue caused by excessive pressure accumulated in the liquid storage bag during flushing, thereby improving the accuracy and safety of flushing.

[0104] A possible implementation method of an embodiment of the present application is that the interactive control unit is also used to control the perfusion unit to perfuse with the perfusion amount set by the user if the intracranial pressure parameter is judged to be lower than the upper limit of the preset intracranial pressure range when no blockage of the drainage tube is detected, and to control the drainage unit to drain with the drainage amount set by the user if the intracranial pressure parameter is judged to be higher than the lower limit of the preset intracranial pressure range.

[0105] In this embodiment, in the normal perfusion and drainage mode, the flushing unit does not work, does not affect the perfusion pressure and perfusion volume, does not affect the normal perfusion and drainage cycle, and the perfusion unit and the drainage unit work independently. The preset parameters set by the user through the input module also include the perfusion volume and the drainage volume. The processing controller controls the perfusion unit and the drainage unit to perform the normal perfusion and drainage mode according to the received perfusion volume and drainage volume.

[0106] Among them, the perfusion unit works when the intracranial pressure parameter reaches the perfusion condition, and the perfusion condition is that the intracranial pressure parameter is lower than the preset upper limit of the intracranial pressure range. The processing controller sends an instruction to control the perfusion pathway switch to open, and the liquid in the perfusion fluid bag passes through the peristaltic pump and the perfusion pathway switch in turn, and flows into the patient's ventricle to complete the perfusion. Of course, the perfusion pathway switch can also be opened at a set frequency, for example, the perfusion pathway switch is controlled to open once every 10 seconds to execute a perfusion volume of 1 ml; the drainage unit works when the intracranial pressure parameter reaches the drainage condition, and the drainage condition is that the intracranial pressure parameter is higher than the preset lower limit of the intracranial pressure range. The processing controller sends an instruction to control the drainage pathway switch to open to drain the patient's ventricular fluid. It can be understood that the higher the intracranial pressure, the greater the drainage flow.

[0107] When no blockage of the drainage tube is detected, the embodiment of the present application controls the perfusion unit and the drainage unit to execute the normal perfusion and drainage mode, maintains the intracranial pressure within a preset intracranial pressure range, and achieves the effects of flushing blood clots and preventing infection.

[0108] Different from the above embodiments, which utilize a liquid storage bag to remove the blockage of the drainage tube, this embodiment utilizes the "water hammer effect" to remove the blockage of the drainage tube by controlling the perfusion passage switch and the drainage passage switch. Specifically, in a possible implementation, the flushing unit includes a perfusion passage switch and a drainage passage switch;

[0109] The interactive control unit is also used to control the perfusion unit and the drainage unit to perform enhanced perfusion and drainage operations alternately according to a preset rhythm when the drainage tube is blocked;

[0110] Among them, alternatingly performing enhanced perfusion and drainage operations according to a preset rhythm includes: after the perfusion pathway switch is opened and the drainage pathway switch is closed for continuous perfusion for a first preset time period, the perfusion pathway switch is closed and the drainage pathway switch is opened to drain the fluid in the patient's ventricles into the drainage bag and continue drainage for a second preset time period, and the operations are performed alternately in sequence.

[0111] In this embodiment, the perfusion pathway switch is turned on and the drainage pathway switch is closed, and liquid is pumped into the perfusion pathway by a peristaltic pump to increase the pressure in the perfusion pathway. The obstruction at the drainage hole is flushed out of the hole first by the pressure difference between the perfusion pathway and the patient's ventricle, and the patient's ventricle pressure is appropriately increased. Then the drainage pathway switch is controlled to open and the perfusion switch is closed, and the obstruction near the drainage tube opening is flushed into the drainage tube through the opening by using the greater pressure difference between the patient's ventricle and the drainage tube, thereby unblocking the blocked channel. Repeat the above operation, and to a certain extent use the "water hammer effect" to expand the pressure difference inside and outside the drainage hole to unblock the blocked drainage hole, until the blocked pipeline is unblocked, that is, the intracranial pressure parameter is in the preset intracranial pressure range and the drainage volume parameter is in the preset drainage volume range, and the current unblocking mode is switched to the normal perfusion and drainage mode. Among them, the first preset time length and the second preset time length are affected by factors such as the specifications of the drainage tube and the drainage site, and can be set by medical staff based on clinical experience and medical knowledge. The optimal first preset time length and second preset time length can also be determined by experiments under different conditions. After the medical staff selects specific conditions through the interactive control unit, the appropriate first preset time length and second preset time length are automatically recommended. This embodiment does not make specific limitations.

[0112] The embodiment of the present application expands the pressure difference between the inside and outside of the drainage hole through the dredging mode, thereby more effectively relieving the blockage of the drainage tube.
